Title Pilot Neil Armstrong and X-15 #1
Full Description Dryden pilot Neil Armstrong is seen here next to the X-15 ship #1 (56-6670) after a research flight. The X-15 was a rocket-powered aircraft 50 feet long with a wingspan of 22 feet. It was a missile-shaped vehicle with an unusual wedge-shaped vertical tail, thin stubby wings, and unique side fairings that extended along the side of the fuselage. The X-15 was flown over a period of nearly 10 years, from June 1959 to October 1968. It set the world's unofficial speed and altitude records. Information gained from the highly successful X-15 program contributed to the development of the Mercury, Gemini, and Apollo manned spaceflight programs, and also the Space Shuttle program. The X-15s made a total of 199 flights, and were manufactured by North American Aviation. X-15-1, serial number 56-6670, is now located at the National Air and Space Museum, Washington DC. North American X-15A- 2, serial number 56-6671, is at the United States Air Force Museum, Wright-Patterson AFB, Ohio. X-15-3, serial number 56-6672, crashed on November 15, 1967, resulting in the death of Major Michael J. Adams.

Project Description In a turbulent era of 1960s Cold War confrontations, moon race headlines, and war in southeast Asia, eight military and civilian test pilots flew the radical X-15 rocket plane out of the atmosphere and into the record books, earning astronaut status. Until today, three of those early astronaut test pilots never received official recognition of their lofty membership as astronauts because only the military had astronaut wings to confer on their pilots at that time. Civilian NASA pilots had no such badge. That inequity was rectified on August 23, 2005, when retired NASA pilot Bill Dana, and family members representing deceased pilots John B. McKay and Joseph A. Walker, received civilian astronaut wings acknowledging their flights above 264,000 feet altitude -- 50 miles high. The men were honored in a quiet ceremony at NASA's Dryden Flight Research Center on Edwards Air Force Base in California, site of their achievements. Bill Dana was philosophical about it: NASA pilots didn't wear wings anyway, and the concept of winning special wings was probably more crucial to a military pilot's career ladder, he explained. Dana's first of two flights into space took him 58.13 miles above the Mojave Desert on Nov. 1, 1966 on a mission to collect micrometeorite samples, while also learning about issues of sky brightness at that height. Joe Walker's third X-15 foray into space claimed the unofficial world altitude record of 354,200 feet, or 67.08 miles, on Aug. 22, 1963. Walker's unofficial record also marked the highest altitude to which the X-15 was ever flown. John McKay attained 295,600 feet altitude, or 55.98 miles, on Sept. 28, 1965 during during a flight that investigated several research experiments. The X-15 program used three piloted hypersonic rocket planes to fly as high as 67 miles and as fast as nearly seven times the speed of sound. Volumes of test data gleaned from 199 X-15 missions from 1959 through 1968 helped shape the successful Mercury, Gemini, Apollo, and Space Shuttle human spaceflight programs. Two retired X-15s are displayed at the National Air and Space Museum, Washington, D.C., and the Air Force Museum, Dayton, Ohio.

Photo Description NASA test pilot Neil Armstrong is seen here next to the X-15 ship #1 (56-6670) after a research flight. Neil A. Armstrong joined the National Advisory Committee for Aeronautics (NACA) at the Lewis Flight Propulsion Laboratory (later NASA?s Lewis Research Center, Cleveland, Ohio, and today the Glenn Research Center) in 1955. Later that year, he transferred to the NACA?s High-Speed Flight Station (today, NASA?s Dryden Flight Research Center) at Edwards Air Force Base in California as an aeronautical research scientist and then as a pilot, a position he held until becoming an astronaut in 1962. He was one of nine NASA astronauts in the second class to be chosen. As a research pilot Armstrong served as project pilot on the F-100A and F-100C aircraft, F-101, and the F-104A. He also flew the X-1B, X-5, F-105, F-106, B-47, KC-135, and Paresev. He left Dryden with a total of over 2450 flying hours. He was a member of the USAF-NASA Dyna-Soar Pilot Consultant Group before the Dyna-Soar project was cancelled, and studied X-20 Dyna-Soar approaches and abort maneuvers through use of the F-102A and F5D jet aircraft. Armstrong was actively engaged in both piloting and engineering aspects of the X-15 program from its inception. He completed the first flight in the aircraft equipped with a new flow-direction sensor (ball nose) and the initial flight in an X-15 equipped with a self-adaptive flight control system. He worked closely with designers and engineers in development of the adaptive system, and made seven flights in the rocket plane from December 1960 until July 1962. During those fights he reached a peak altitude of 207,500 feet in the X-15-3, and a speed of 3,989 mph (Mach 5.74) in the X-15-1. Armstrong was born August 5, 1930, in Wapakoneta, Ohio. He attended Purdue University, earning his Bachelor of Science degree in aeronautical engineering in 1955. During the Korean War, which interrupted his engineering studies, he flew 78 combat missions in F9F-2 jet fighters. He was awarded the Air Medal and two Gold Stars. He later earned a Master of Science degree in aerospace engineering from the University of Southern California. Armstrong has a total of 8 days and 14 hours in space, including 2 hours and 48 minutes walking on the Moon. In March 1966 he was commander of the Gemini 8 orbital space flight with David Scott as pilot?the first successful docking of two vehicles in orbit. On July 20, 1969, during the Apollo 11 lunar mission, he became the first human to set foot on the Moon. From 1969 to 1971 he was Deputy Associate Administrator for Aeronautics at NASA Headquarters, and resigned from NASA in August 1971 to become Professor of Engineering at the University of Cincinnati, a post he held until 1979. He became Chairman of the Board of Cardwell International, Ltd., in Lebanon, Ohio, in 1980 and served in that capacity until 1982. During the years 1982-1992, Armstrong was chairman of Computing Technologies for Aviation, Inc., in Charlottesville,, Virginia. From 1981 to 1999, he served on the board of directors for Eaton Corp. He served as chairman of the board of AIL Systems, Inc. of Deer Park, New York, until 1999 and in 2000 was elected chairman of the board of EDO Corp., a manaufacturer of electronic and mechanical systems for the aerospace, defense and industrial markets, based in New York City. From 1985 to 1986, Armstrong served on the National Commission on Space, a presidential committee to develop goals for a national space program into the 21st century. He was also Vice Chairman of the committee investigating the Space Shuttle Challenger disaster in 1986. During the early 1990s he hosted an aviation documentary series for television entitled First Flights.
Project Description The X-15 was a rocket-powered aircraft 50 ft long with a wingspan of 22 ft. It was a missile-shaped vehicle with an unusual wedge-shaped vertical tail, thin stubby wings, and unique fairings that extended along the side of the fuselage. The X-15 weighed about 14,000 lb empty and approximately 34,000 lb at launch. The XLR-99 rocket engine, manufactured by Thiokol Chemical Corp., was pilot controlled and was capable of developing 57,000 lb of rated thrust (actual thrust reportedly climbed to 60,000 lb). North American Aviation built three X-15 aircraft for the program. The X-15 research aircraft was developed to provide in-flight information and data on aerodynamics, structures, flight controls, and the physiological aspects of high-speed, high-altitude flight. A follow-on program used the aircraft as a testbed to carry various scientific experiments beyond the Earth's atmosphere on a repeated basis. For flight in the dense air of the usable atmosphere, the X-15 used conventional aerodynamic controls such as rudder surfaces on the vertical stabilizers to control yaw and canted horizontal surfaces on the tail to control pitch when moving in synchronization or roll when moved differentially. For flight in the thin air outside of the appreciable Earth's atmosphere, the X-15 used a reaction control system. Hydrogen peroxide thrust rockets located on the nose of the aircraft provided pitch and yaw control. Those on the wings provided roll control. Because of the large fuel consumption, the X-15 was air launched from a B-52 aircraft at 45,000 ft and a speed of about 500 mph. Depending on the mission, the rocket engine provided thrust for the first 80 to 120 sec of flight. The remainder of the normal 10 to 11 min. flight was powerless and ended with a 200-mph glide landing. Generally, one of two types of X-15 flight profiles was used: a high-altitude flight plan that called for the pilot to maintain a steep rate of climb, or a speed profile that called for the pilot to push over and maintain a level altitude. The X-15 was flown over a period of nearly 10 years--June 1959 to Oct. 1968--and set the world's unofficial speed and altitude records of 4,520 mph (Mach 6.7) and 354,200 ft (over 67 mi) in a program to investigate all aspects of piloted hypersonic flight. Information gained from the highly successful X-15 program contributed to the development of the Mercury, Gemini, and Apollo manned spaceflight programs, and also the Space Shuttle program. The X-15s made a total of 199 flights and were manufactured by North American Aviation. X-15-1, serial number 56-6670, is now located at the National Air and Space Museum, Washington DC. North American X-15A-2, serial number 56-6671, is at the United States Air Force Museum, Wright-Patterson AFB, Ohio. The X-15-3, serial number 56-6672, crashed on 15 November 1967, resulting in the death of Maj. Michael J. Adams.

Photo Description NASA pilot Neil Armstrong is seen here in the cockpit of the X-15 ship #1 (56-6670) after a research flight. A U.S. Navy pilot in the Korean War who flew 78 combat missions in F9F-2 jet fighters and who was awarded the Air Medal and two Gold Stars, Armstrong graduated from Purdue University in 1955 with a bachelor degree in aeronautical engineering. That same year, he joined the National Advisory Committee for Aeronautics' Lewis Flight Propulsion Laboratory in Cleveland, Ohio (today, the NASA Glenn Research Center). In July 1955, Armstrong transferred to the High-Speed Flight Station (HSFS, as Dryden Flight Research Center was then called) as an aeronautical research engineer. Soon thereafter, he became a research pilot. For the first few years at the HSFS, Armstrong worked on a number of projects. He was a pilot on the Navy P2B-1S used to launch the D-558-2 and also flew the F-100A, F-100C, F-101, F-104A, and X-5. His introduction to rocket flight came on August 15, 1957, with his first flight (of four, total) on the X-1B. He then became one of the first three NASA pilots to fly the X-15, the others being Joe Walker and Jack McKay. (Scott Crossfield, a former NACA pilot, flew the X-15 first but did so as a North American Aviation pilot.)
Project Description Adams., The X-15 was a rocket-powered aircraft. The original three aircraft were about 50 ft long with a wingspan of 22 ft. The modified #2 aircraft (X-15A-2 was longer.) They were a missile-shaped vehicles with unusual wedge-shaped vertical tails, thin stubby wings, and unique side fairings that extended along the side of the fuselage.

LLRV in flight and landing o …
Title LLRV in flight and landing on ramp
Description This 26-second video clip shows the LLRV flying and landing. The LLRV's, humorously referred to as "flying bedsteads," were created by a predecessor of the NASA Dryden Flight Research Center and Bell Aerosystems Company, Niagra Falls, New York, to study and analyze piloting techniques needed to fly and land the tiny Apollo Lunar Module in the Moon's airless environment. (Dryden was known simply as the NASA Flight Research Center from 1959 to 1976.) Success of the LLRV's led to the building of three Lunar Landing Training Vehicles (LLTV) used by Apollo astronauts at the Manned Spacecraft Center, Houston, Texas, predecessor of the NASA Johnson Space Center. Apollo 11 astronaut, Neil Armstrong -- first human to step onto the Moon's surface -- said the mission would not have been successful without the type of simulation that resulted from the LLRV's. When Apollo planning was underway in 1960, NASA was looking for a simulator to profile the descent to the Moon's surface. Three concepts developed: an electronic simulator, a tethered device, and the ambitious Flight Research Center (FRC) contribution, a free-flying vehicle. All three became serious projects, but eventually the FRC's LLRV became the most significant one. Hubert Drake is credited with originating the idea, while Donald Bellman and Gene Matranga were senior engineers on the project, with Bellman the project manager. After conceptual planning and meetings with engineers from Bell Aerosystems, a company with experience in vertical takeoff and landing (VTOL) aircraft, NASA issued Bell a $50,000 study contract in December 1961. Bell had independently conceived a similar, free-flying simulator, and out of this study came the headquarters' endorsement of the LLRV concept, resulting in a $3.6 million production contract awarded to Bell February 1, 1963, for delivery of the first of two vehicles for flight studies at the FRC within 14 months. Built of aluminum alloy trusses and shaped like a giant four-legged bedstead, the vehicle was to simulate a lunar landing profile. To do this, the LLRV had a General Electric CF-700-2V turbofan engine mounted vertically in a gimbal, with 4200 pounds of thrust. The engine got the vehicle up to the test altitude and was then throttled back to support five-sixths of the vehicle's weight, simulating the reduced gravity of the Moon. Two hydrogen peroxide lift rockets with thrust that could be varied from 100 to 500 pounds handled the LLRV's rate of descent and horizontal movement. Sixteen smaller hydrogen peroxide rockets, mounted in pairs, gave the pilot control in pitch, yaw, and roll. As safety backups on the LLRV, six 500-pound rockets could take over the lift function and stabilize the craft for a moment if the main jet engine failed. The pilot had a zero-zero ejection seat that would then lift him away to safety. The two LLRV's were shipped from Bell to the FRC in April 1964, with program emphasis on vehicle No. 1. It was first readied for captured flight, on a tilt-table affair. The scene then shifted to the old South Base area of Edwards. On the day of the first flight, October 30, 1964, research pilot Joe Walker flew it three times for a total of just under 60 seconds to a peak altitude of ten feet (three meters). Later flights were shared between Walker, another Center pilot named Don Mallick, the Army's Jack Kleuver, NASA Manned Spacecraft Center, Houston, Texas, pilots Joseph Algranti and H.E. "Bud" Ream. NASA had accumulated enough data from the LLRV flight program at the FRC by mid-1966 to give Bell a contract to deliver three LLTVs at a cost of $2.5 million each. In December 1966 vehicle No. 1 was shipped to Houston, followed by No. 2 in January 1967, within weeks of its first flight. Modifications already made to No. 2 had given the pilot a three-axis side control stick and a more restrictive cockpit view, both features of the real Lunar Module that would later be flown by the astronauts down to the Moon's surface. When the LLRV's arrived at Houston, where research pilots would learn how to become LLTV instructor pilots, No. 2 had been flown just seven times while No. 1, the veteran, had a total of 198 flights. In December 1967, the first of the LLTV's joined the FRC's LLRV's to eventually make up the five-vehicle training and simulator fleet. Three of the five vehicles were later destroyed in crashes at Houston - LLRV No. 1 in May 1968 and two LLTV's, in December 1968 and January 1971. The two accidents in 1968, before the first lunar landing, did not deter Apollo program managers who enthusiastically relied on the vehicles for simulation and training. Donald "Deke" Slayton, then NASA's astronaut chief, said there was no other way to simulate a Moon landing except by flying the LLTV. LLRV No. 2 was eventually returned to Dryden, where it is on display as a silent artifact of the Center's contribution to the Apollo program.

Description In this photo of the M2-F1 lifting body and the Paresev 1B on the ramp, the viewer sees two vehicles representing different approaches to building a research craft to simulate a spacecraft able to land on the ground instead of splashing down in the ocean as the Mercury capsules did. The M2-F1 was a lifting body, a shape able to re-enter from orbit and land. The Paresev (Paraglider Research Vehicle) used a Rogallo wing that could be (but never was) used to replace a conventional parachute for landing a capsule-type spacecraft, allowing it to make a controlled landing on the ground. The wingless, lifting body aircraft design was initially conceived as a means of landing an aircraft horizontally after atmospheric reentry. The absence of wings would make the extreme heat of re-entry less damaging to the vehicle. In 1962, Dryden management approved a program to build a lightweight, unpowered lifting body as a prototype to flight test the wingless concept. It would look like a "flying bathtub," and was designated the M2-F1, the "M" referring to "manned" and "F" referring to "flight" version. It featured a plywood shell placed over a tubular steel frame crafted at Dryden. Construction was completed in 1963. The first flight tests of the M2-F1 were over Rogers Dry Lake at the end of a tow rope attached to a hopped-up Pontiac convertible driven at speeds up to about 120 mph. This vehicle needed to be able to tow the M2-F1 on the Rogers Dry Lakebed adjacent to NASA's Flight Research Center (FRC) at a minimum speed of 100 miles per hour. To do that, it had to handle the 400-pound pull of the M2-F1. Walter "Whitey" Whiteside, who was a retired Air Force maintenance officer working in the FRC's Flight Operations Division, was a dirt-bike rider and hot-rodder. Together with Boyden "Bud" Bearce in the Procurement and Supply Branch of the FRC, Whitey acquired a Pontiac Catalina convertible with the largest engine available. He took the car to Bill Straup's renowned hot-rod shop near Long Beach for modification. With a special gearbox and racing slicks, the Pontiac could tow the 1,000-pound M2-F1 110 miles per hour in 30 seconds. It proved adequate for the roughly 400 car tows that got the M2-F1 airborne to prove it could fly safely and to train pilots before they were towed behind a C-47 aircraft and released. These initial car-tow tests produced enough flight data about the M2-F1 to proceed with flights behind the C-47 tow plane at greater altitudes. The C-47 took the craft to an altitude of 12,000 where free flights back to Rogers Dry Lake began. Pilot for the first series of flights of the M2-F1 was NASA research pilot Milt Thompson. Typical glide flights with the M2-F1 lasted about two minutes and reached speeds of 110 to l20 mph. A small solid landing rocket, referred to as the "instant L/D rocket," was installed in the rear base of the M2-F1. This rocket, which could be ignited by the pilot, provided about 250 pounds of thrust for about 10 seconds. The, Rogallo wing was never used on a spacecraft, it revolutionized the sport of hang gliding, and a different but related kind of wing will be used on the X-38 technology demonstrator for a crew return vehicle from the International space station., referred to as a `space frame.' The keel and leading edges of the wings were constructed of 2 1/2-inch diameter aluminum tubing. The leading edge sweep angle was held constant at 50 degrees by a rigid spreader bar. Additional wing structure fabricated of steel tubing ensured structural integrity. Seven weeks after the project was initiated the team rolled out the Paresev 1. It resembled a grown-up tricycle, with a rudimentary seat, an angled tripod mast, and, perched on top of the mast, a Rogallo-type parawing. The pilot sat out in the open, strapped in the seat, with no enclosure of any kind. He controlled the descent rate by tilting the wing fore and aft, and turned by tilting the wing from side to side with a control stick that came from overhead. NASA registered the Paresev, the first NASA research airplane to be constructed totally "in-house," with the Federal Aviation Administration on February 12, 1962. Flight testing started immediately. There was one space frame built called the Paresev that used four different wing types. Paresev 1 had a linen membrane, with the control stick coming from overhead in front of the pilots seat. Paresev 1A had a regulation control stick and a Dacron membrane. Paresev 1B had a smaller Dacron membrane with the space frame remaining the same. Paresev 1C used a half-scale version of the inflatable Gemini parawing with a small change to the space frame. All `space frames,' regardless of the parawing configuration, had a shield with "Paresev 1-A" and the NASA meatball on the front of the vehicle. PARESEV-1 After the space frame was completed a sailmaker was asked to sew the wing membrane according to the planform developed by NASA Flight Research Center personnel. He suggested using Dacron instead of the linen fabric chosen, but yielded to the engineers' specs. A nylon bolt rope was attached in the trailing edge of the 150-square-foot wing membrane. The rope was unrestrained except at the wing tips and was therefore free to equalize the load between the two lobes of the wing. This worked reasonably well, but flight tests proved the wing to be too flexible with it flapping and bulging in alarming ways. The poor membrane design led to trailing edge flutter, with longitudinal and lateral stick forces being severe. A number of different rigging modifications to improve the flying characteristics were tried, but very few were successful and none were predictable. Everything seemed to affect stick forces in the worst way. The fifth flight aloft lasted 10 seconds. On a ground tow the Paresev and pilot fell 10 feet. Considerable damage was done to the Paresev with the pilot, Bruce Peterson, being taken to the base hospital. Injuries sustained by the pilot were not serious. After this accident the Paresev was extensively rebuilt and renamed, Paresev-1A. PARESEV 1-A The sailmaker was asked again to construct a 150-square-foot membrane the way he wanted to. The resulting wing membrane had excellent contours in flight and, rocket could be used to extend the flight time near landing if needed. More than 400 ground tows and 77 aircraft tow flights were carried out with the M2-F1. The success of Dryden's M2-F1 program led to NASA's development and construction of two heavyweight lifting bodies based on studies at NASA's Ames and Langley research centers--the M2-F2 and the HL-10, both built by the Northrop Corporation, and the U.S. Air Force's X-24 program, with an X-24A and -B built by Martin. The Lifting Body program also heavily influenced the Space Shuttle program. The M2-F1 program demonstrated the feasibility of the lifting body concept for horizontal landings of atmospheric entry vehicles. It also demonstrated a procurement and management concept for prototype flight test vehicles that produced rapid results at very low cost (approximately $50,000, excluding salaries of government employees assigned to the project). The Paresev (Paraglider Rescue Vehicle) was an indirect outgrowth of kite-parachute studies by NACA Langley engineer Francis M. Rogallo. In the early 1960s the "Rogallo wing" seemed an excellent means of returning a spacecraft to Earth. The delta wing design was patented by Mr. Rogallo. In May 1961, Robert R. Gilruth, director NASA's Space Task Group, requested studies of an inflatable Rogallo-type "Parawing" for spacecraft. Several companies responded, North American Aviation produced the most acceptable concept and development was contracted to that company. In November 1961 NASA Headquarters launched a paraglider development program, with Langely doing wind-tunnel studies and the NASA Flight Research Center supporting the North American test program. The North American concept was a capsule type vehicle with a stowed "parawing" that could be deployed and controlled from within for a landing more like an airplane instead of a "splash down" in the ocean as was the practice in the Mercury and later the Gemini and Apollo programs. The logistics became enormous and the price exorbitant, besides which, NASA pilots and engineers felt some baseline experience like building a vehicle and flying a Parawing should be accomplished first. The Paresev (Paraglider Research Vehicle) was used to gain in-flight experience with four different membranes (wings) and was not used to develop the more complicated inflatable deployment system. The Paresev was designed by Charles Richard, of the Flight Research Center's Vehicle and System Dynamics Branch, with the rest of the team being: engineers Richard Klein, Gary Layton, John Orahood, and Joe Wilson, Frank Fedor and LeRoy Barto from the Maintenance and Manufacturing Branch, Project Manager Victor Horton, with Gary Layton becoming Project Manager later on in the Program. Mr. Paul Bikle, Director of the Center, gave instructions that were short and to the point: build a single-seat Paraglider and "do it quick and cheap." The Paresev was unpowered, the "fuselage" an open framework fabricated of welded 4130 steel tubing, was made from 6 ounce Dacron. The space frame was rebuilt with more sophistication than the Paresev 1 had. The shock absorbers were Ford automotive parts, the wing universal joint was a 1948 Pontiac part, and the tires and wheels were from a Cessna 175 aircraft. The overhead stick was replaced with a stick and pulley arrangement that operated more like conventional aircraft controls. This vehicle had much improved stick forces and handling qualities. The instrumentation used to obtain data was quite crude, partially as a result of the desire to keep the program simple and low in cost and also because there was no onboard power. To measure performance, technicians installed a large alpha vane on the wing apex with a scale at the trailing edge that the pilot could read directly. A curved bubble level measured the vehicle's attitude, and a Fairchild camera recorded the glide slope PARESEV 1-B The Paresev 1-B used the Paresev 1-A space frame with a smaller Dacron wing (100 square feet) and was flight tested to evaluate its handling qualities with lower lift-to-drag values. One NASA project engineer described its gliding ability as "pretty scary." PARESEV 1-C The space frame of the vehicle remained almost unchanged from the earlier vehicles. However, a new control box gave the pilot the ability to increase or decrease the nitrogen in the inflatable wing supports to compensate for the changing density of the air. Two bottles of nitrogen provided an extra supply of nitrogen. The vehicle featured a partially inflatable wing. The whole wing was not inflatable, the three chambers that acted as spars and supported the wing inflated. The center spar ran fore and aft and measured 191 inches, two other inflatable spars formed the leading edges. These three compartments were filled with nitrogen under pressure to make them rigid. The Paresev in this configuration was expected to closely approximate the aerodynamic characteristics that would be encountered with the Gemini space capsule with a parawing extended. The Paresev was very unstable in flight with this configuration. The first Paresev flights began with tows across the dry lakebed, in 1962, using a NASA vehicle, an International Harvester carry-all (6 cylinder). Eventually ground and airtows were done using a Stearman sport biplane (450 hp), a Piper Super Cub (150-180 hp), Cessna L-19 (200 hp Bird Dog) and a Boeing-Vertol HC-1A. Speed range of the Paresev was about 35-65 mph. The Paresev completed nearly 350 flights during a research program from 1962 until 1964. Pilots flying the Paresev included NASA pilots Milton Thompson, Bruce Peterson, and Neil Armstrong from Dryden, Robert Champine from Langley, and astronaut Gus Grissom, plus North American test pilot Charles Hetzel. The Paresev was legally transferred to the National Air and Space Museum of the Smithsonian Institute, Washington, D.C. Despite its looks, the Paresev was a useful research aircraft that helped develop a new way to fly. Although the

Description 44-84958) used for low-speed chase missions, as well as support and liaison flights. On the right side of the B-47 is the first D-558-1. Originally given the Navy number 37970, it was flown as part of the Douglas contractor program. When this was completed, the aircraft was turned over to the NACA on April 11, 1949. Although the aircraft was designation "NACA 140," it was never flown again. Instead, it was used to provide spare parts to keep the third D-558-1 in operation. In this photo the aircraft is partially disassembled. The final aircraft is the first X-5 (Air Force 50-1838). This was a research aircraft used to test the concept of pivoting wings which could change their sweep angle in flight. The results were mixed, the X-5 had vicious stall behavior due to the poor position of the tail and stabilizers. The mechanism used by the "variable-sweep wing" was also complex, which limited its usefulness. Despite these problems, the X-5's primary advantage was that it was equivalent to a whole family of research aircraft. It could provide transonic data at sweep angles up to 60 degrees--the same as the delta wing XF-92A. The Dryden Flight Research Center, NASA's premier installation for aeronautical flight research, celebrated its 50th anniversary in 1996. Dryden is the "Center of Excellence" for atmospheric flight operations. The Center's charter is to research, develop, verify, and transfer advanced aeronautics, space, and related technologies. It is located at Edwards, Calif., on the western edge of the Mojave Desert, 80 miles north of Los Angeles. Dryden's history dates back to the early fall of 1946, when a group of five aeronautical engineers arrived at what is now Edwards from the NACA's Langley Memorial Aeronautical Laboratory, Hampton, Va. Their goal was to prepare for the X-l supersonic research flights in a joint NACA-U.S. Army Air Forces-Bell Aircraft Corp. program. NACA--the National Advisory Committee for Aeronautics--was the predecessor of today's NASA. Since the days of the X-l, the first aircraft to fly faster than the speed of sound, the installation has grown in size and significance and is associated with many important developments in aviation -- supersonic and hypersonic flight, wingless lifting bodies, digital fly-by-wire, supercritical and forward-swept wings, and the space shuttles. Its name has changed many times over the years. From 14 November 1949 to 1 July 1954 it bore the name NACA High-Speed Flight Research Station., In the center foreground of this 1953 hanger photo is the YF-84A (NACA 134/Air Force 45-59490) used for vortex generator research. It arrived on November 28, 1949, and departed on April 21, 1954. Beside it is the third D-558-1 aircraft (NACA 142/Navy 37972). This aircraft was used for a total of 78 transonic research flights from April 1949 to June 1954. It replaced the second D-558-1, lost in the crash which killed Howard Lilly. Just visible on the left edge is the nose of the first D-558-2 (NACA 143/Navy 37973). Douglas turned the aircraft over to NACA on August 31, 1951, after the contractor had completed its initial test flights. NACA only made a single flight with the aircraft, on September 17, 1956, before the program was cancelled. In the center of the photo is the B-47A (NACA 150/Air Force 49-1900). The B-47 jet bomber, with its thin, swept-back wings, and six podded engines, represented the state of the art in aircraft design in the early 1950s. The aircraft undertook a number of research activities between May 1953 and its 78th and final research flight on November 22, 1957. The tests showed that the aircraft had a buffeting problem at speeds above Mach 0.8. Among the pilots who flew the B-47 were later X-15 pilots Joe Walker, A. Scott Crossfield, John B. McKay, and Neil A. Armstrong. On the right side of the B-47 is NACA's X-1 (Air Force 46-063). The second XS-1 aircraft built, it was fitted with a thicker wing than that on the first aircraft, which had exceeded Mach 1 on October 14, 1947. Flight research by NACA pilots indicated that this thicker wing produced 30 percent more drag at transonic speeds compared to the thinner wing on the first X-1. After a final flight on October 23, 1951, the aircraft was grounded due to the possibility of fatigue failure of the nitrogen spheres used to pressurize the fuel tanks. At the time of this photo, in 1953, the aircraft was in storage. In 1955, the aircraft was extensively modified, becoming the X-1E. In front of the X-1 is the XF-92A (Air Force 46-682). Unlike the X-1 and D-558 aircraft, the XF-92A was not designed as a research aircraft, but as the prototype of a delta-wing fighter. While the effort was unsuccessful, the XF-92A offered the chance to test a delta wing aircraft. A brief series of 25 flights were made using the aircraft in 1953. These showed the aircraft had violent pitch-up tendencies during turns. Despite the problems, the XF-92A contributed to later delta wing aircraft, like the F-102, F-106, and B-58. Behind the B-47, in the back of the hangar, are four other aircraft. From left to right, they are the second X-4 (Air Force 46-677) research aircraft. It was operated by the NACA from May 8, 1950, to March 22, 1954, when it left the High-Speed Flight Research Station for the U.S. Air Force Museum. It was designed to test the use of swept wings but no horizontal stabilizers. This proved to have poor transonic stability. Next to it is the ETF-51D Mustang (NACA 148/Air Force

Title Neil A. Armstrong
Description Neil A. Armstrong joined the National Advisory Committee for Aeronautics at the Lewis Flight Propulsion Laboratory, Cleveland, Ohio, in 1955. He transferred to the NACA High-Speed Flight Station at Edwards Air Force Base, California, in July 1955, as an aeronautical research scientist. He became a research pilot later that year. Neil was named as one of nine astronauts for NASA's Gemini and Apollo Projects, leaving the Center for the National Aeronautics and Space Administration's Manned Spacecraft Center, Houston, Texas, in September 1962. Upon graduation from High School in 1947, Armstrong received a scholarship from the U.S. Navy. He enrolled at Purdue University to begin the study of aeronautical engineering. In 1949, the Navy called him to active duty and he became a navy pilot. In 1950, he was sent to Korea where he flew 78 combat missions from the carrier USS Essex in a Grumman F9F-2 Panther. He received the Air Medal and two Gold Stars. In 1952, Armstrong returned to Purdue University and graduated with a bachelors degree in aeronautical engineering in 1955. He later earned a masters degree in aerospace engineering from the University of Southern California. At the High-Speed Flight Station (which later became the NASA Dryden Flight Research Center) Armstrong served as project pilot on the North American F-100A and -C aircraft, McDonnell F-101, and the Lockheed F-104A. He also flew the Bell X-1B (4 flights, first on August 15, 1957), Bell X-5 (one flight, the last in the program, on October 25, 1955) and the Paresev. On November 30, 1960, Armstrong made his first flight in the X-15. He made a total of seven flights in the rocket plane reaching an altitude of 207,500 feet in the X-15-3 and a Mach number of 5.74 (3,989 mph) in the X-15-1. He left the Flight Research Center with a total of 2450 flying hours in more than 50 aircraft types. He was a member of the USAF-NASA Dyna-Soar Pilot Consultant Group, and studied X-20 Dyna-Soar approaches and abort maneuvers through use of the F-102A and F5D jet aircraft. Armstrong later accumulated a total of 8 days and 14 hours in space, including 2 hours and 48 minutes walking on the Moon. In March 1966, he was commander of the Gemini 8 mission that performed the first successful docking of two vehicles in space. As spacecraft commander for the Apollo 11 lunar mission, on July 20, 1969, he became the first human to set foot on the Moon. In 1970 he was appointed Deputy Associate Administrator for Aeronautics at NASA Headquarters. He resigned in 1971. Neil wrote several technical reports and presented a number of research papers. In June 1962, the Octave Chanute Award was presented to Neil by the Institute of the Aerospace Sciences. Other awards received by Neil have included the NASA Distinguished Service Medal and the NASA Exceptional Service Medal.

Title P-51 Mustang on Lakebed
Description This photograph shows a NACA research pilot running up the engine of the F-51 Mustang on the taxiway adjacent to Rogers Dry Lake at the NACA High-Speed Flight Station in 1955. A P-51 Mustang, redesignated an F-51 Mustang, was transferred from the Langley Aeronautical Laboratory to the NACA High-Speed Flight Research Station (now the NASA Dryden Flight Research Center) at Edwards Air Force Base in California, in 1950. The P-51 Mustang was the first aircraft to employ the NACA laminar-flow airfoil design and could dive to around Mach number 0.8. As an F-51, it was used as a proficiency aircraft at the High Speed Flight Station. A North American P-51Mustang (the P meaning pursuit), redesignated as an F-51 Mustang (with the F standing for fighter), was transferred to the NACA High-Speed Flight Research Station (HSFRS), Edwards, California, from the Langley Aeronautical Laboratory, Hampton, Virginia, in 1950. This aircraft had been used in wing-flow research at Langley prior to its transfer. The NACA was the National Advisory Committee for Aeronautics, a predecessor of the National Aeronautics and Space Administration (NASA). The HSFRS was a predecessor of NASA's Dryden Flight Research Center, and Langley Aeronautical Laboratory became NASA's Langley Research Center. The P-51 was the first aircraft to employ the NACA laminar-flow airfoil design and could dive to a speed of roughly Mach 0.8. As an F-51 Fighter, instead of a P-51 pursuit aircraft, the aircraft was used as a proficiency aircraft at HSFRS. Records show that the aircraft was also used as a chase and support aircraft 395 times. Neil Armstrong was among the pilots using it to chase some of the X-planes (that is, provide safety support). The P-51 was retired in 1959 as the result of a taxiing mishap.

Description Famed astronaut Neil A. Armstrong, the first man to set foot on the moon during the historic Apollo 11 space mission in July 1969, served for seven years as a research pilot at the NACA-NASA High-Speed Flight Station, now the Dryden Flight Research Center, at Edwards, California, before he entered the space program. Armstrong joined the National Advisory Committee for Aeronautics (NACA) at the Lewis Flight Propulsion Laboratory (later NASA's Lewis Research Center, Cleveland, Ohio, and today the Glenn Research Center) in 1955. Later that year, he transferred to the High-Speed Flight Station at Edwards as an aeronautical research scientist and then as a pilot, a position he held until becoming an astronaut in 1962. He was one of nine NASA astronauts in the second class to be chosen. As a research pilot Armstrong served as project pilot on the F-100A and F-100C aircraft, F-101, and the F-104A. He also flew the X-1B, X-5, F-105, F-106, B-47, KC-135, and Paresev. He left Dryden with a total of over 2450 flying hours. He was a member of the USAF-NASA Dyna-Soar Pilot Consultant Group before the Dyna-Soar project was cancelled, and studied X-20 Dyna-Soar approaches and abort maneuvers through use of the F-102A and F5D jet aircraft. Armstrong was actively engaged in both piloting and engineering aspects of the X-15 program from its inception. He completed the first flight in the aircraft equipped with a new flow-direction sensor (ball nose) and the initial flight in an X-15 equipped with a self-adaptive flight control system. He worked closely with designers and engineers in development of the adaptive system, and made seven flights in the rocket plane from December 1960 until July 1962. During those fights he reached a peak altitude of 207,500 feet in the X-15-3, and a speed of 3,989 mph (Mach 5.74) in the X-15-1. Armstrong has a total of 8 days and 14 hours in space, including 2 hours and 48 minutes walking on the Moon. In March 1966 he was commander of the Gemini 8 orbital space flight with David Scott as pilot - the first successful docking of two vehicles in orbit. On July 20, 1969, during the Apollo 11 lunar mission, he became the first human to set foot on the Moon.

Title Pilot Neil Armstrong in the X-15 #1 cockpit
Description NASA pilot Neil Armstrong is seen here in the cockpit of the X-15 ship #1 (56-6670) after a research flight. A U.S. Navy pilot in the Korean War who flew 78 combat missions in F9F-2 jet fighters and who was awarded the Air Medal and two Gold Stars, Armstrong graduated from Purdue University in 1955 with a bachelor degree in aeronautical engineering. That same year, he joined the National Advisory Committee for Aeronautics' Lewis Flight Propulsion Laboratory in Cleveland, Ohio (today, the NASA Glenn Research Center). In July 1955, Armstrong transferred to the High-Speed Flight Station (HSFS, as Dryden Flight Research Center was then called) as an aeronautical research engineer. Soon thereafter, he became a research pilot. For the first few years at the HSFS, Armstrong worked on a number of projects. He was a pilot on the Navy P2B-1S used to launch the D-558-2 and also flew the F-100A, F-100C, F-101, F-104A, and X-5. His introduction to rocket flight came on August 15, 1957, with his first flight (of four, total) on the X-1B. He then became one of the first three NASA pilots to fly the X-15, the others being Joe Walker and Jack McKay. (Scott Crossfield, a former NACA pilot, flew the X-15 first but did so as a North American Aviation pilot.) The X-15 was a rocket-powered aircraft. The original three aircraft were about 50 ft long with a wingspan of 22 ft. The modified #2 aircraft (X-15A-2 was longer.) They were a missile-shaped vehicles with unusual wedge-shaped vertical tails, thin stubby wings, and unique side fairings that extended along the side of the fuselage. The X-15 weighed about 14,000 lb empty and approximately 34,000 lb at launch. The XLR-99 rocket engine, manufactured by Thiokol Chemical Corp., was pilot controlled and was rated at 57,000 lb of thrust, although there are indications that it actually achieved up to 60,000 lb. North American Aviation built three X-15 aircraft for the program. The X-15 research aircraft was developed to provide in-flight information and data on aerodynamics, structures, flight controls, and the physiological aspects of high-speed, high-altitude flight. A follow-on program used the aircraft as testbeds to carry various scientific experiments beyond the Earth's atmosphere on a repeated basis. For flight in the dense air of the usable atmosphere, the X-15 used conventional aerodynamic controls such as rudder surfaces on the vertical stabilizers to control yaw and movable horizontal stabilizers to control pitch when moving in synchronization or roll when moved differentially. For flight in the thin air outside of the appreciable Earth's atmosphere, the X-15 used a reaction control system. Hydrogen peroxide thrust rockets located on the nose of the aircraft provided pitch and yaw control. Those on the wings provided roll control. Because of the large fuel consumption, the X-15 was air launched from a B-52 aircraft at approximately 45,000 ft and a speed of about 500 mph. Depending on the mission, the rocket, engine provided thrust for the first 80 to 120 sec of flight. The remainder of the normal 10 to 11 min. flight was powerless and ended with a 200-mph glide landing. Generally, one of two types of X-15 flight profiles was used, a high-altitude flight plan that called for the pilot to maintain a steep rate of climb, or a speed profile that called for the pilot to push over and maintain a level altitude. The X-15 was flown over a period of nearly 10 years -- June 1959 to Oct. 1968 -- and set the world's unofficial speed and altitude records of 4,520 mph (Mach 6.7) and 354,200 ft in a program to investigate all aspects of manned hypersonic flight. Information gained from the highly successful X-15 program contributed to the development of the Mercury, Gemini, and Apollo manned spaceflight programs, and also the Space Shuttle program. The X-15s made a total of 199 flights, and were manufactured by North American Aviation. X-15-1, serial number 56-6670, is now located at the National Air and Space Museum, Washington DC. North American X-15A-2, serial number 56-6671, is at the United States Air Force Museum, Wright-Patterson AFB, Ohio. X-15-3, serial number 56-6672, crashed on 15 November 1967, resulting in the death of Maj. Michael J. Adams.

Title Pilot Neil Armstrong with X-15 #1
Description Dryden pilot Neil Armstrong is seen here next to the X-15 ship #1 (56-6670) after a research flight. Armstrong made his first X-15 flight on November 30, 1960, in the #1 X-15. He made his second flight on December 9, 1960, in the same aircraft. This was the first X-15 flight to use the ball nose, which provided accurate measurement of air speed and flow angle at supersonic and hypersonic speeds. The servo-actuated ball nose can be seen in this photo in front of Armstrong's right hand. The X-15 employed a non-standard landing gear. It had a nose gear with a wheel and tire, but the main landing consisted of skids mounted at the rear of the vehicle. In the photo, the left skid is visible, as are marks on the lakebed from both skids. Because of the skids, the rocket-powered aircraft could only land on a dry lakebed, not on a concrete runway. The X-15 was a rocket-powered aircraft. The original three aircraft were about 50 ft long with a wingspan of 22 ft. The modified #2 aircraft (X-15A-2 was longer.) They were a missile-shaped vehicles with unusual wedge-shaped vertical tails, thin stubby wings, and unique side fairings that extended along the side of the fuselage. The X-15 weighed about 14,000 lb empty and approximately 34,000 lb at launch.

For flight in the dense air of the usable atmosphere, the X-15 used conventional aerodynamic controls such as rudder surfaces on the vertical stabilizers to control yaw and movable horizontal stabilizers to control pitch when moving in synchronization or roll when moved differentially. For flight in the thin air outside of the appreciable Earth's atmosphere, the X-15 used a reaction control system. Hydrogen peroxide thrust rockets located on the nose of the aircraft provided pitch and yaw control. Those on the wings provided roll control. Because of the large fuel consumption, the X-15 was air launched from a B-52 aircraft at approximately 45,000 ft and a speed of about 500 mph. Depending on the mission, the rocket engine provided thrust for the first 80 to 120 sec of flight. The remainder of the normal 10 to 11 min. flight was powerless and ended with a 200-mph glide landing. Generally, one of two types of X-15 flight profiles was used, a high-altitude flight plan that called for the pilot to maintain a steep rate of climb, or a speed profile that called for the pilot to push over and maintain a level altitude. The X-15, was flown over a period of nearly 10 years -- June 1959 to Oct. 1968 -- and set the world's unofficial speed and altitude records of 4,520 mph (Mach 6.7) and 354,200 ft in a program to investigate all aspects of manned hypersonic flight. Information gained from the highly successful X-15 program contributed to the development of the Mercury, Gemini, and Apollo manned spaceflight programs, and also the Space Shuttle program. The X-15s made a total of 199 flights, and were manufactured by North American Aviation. X-15-1, serial number 56-6670, is now located at the National Air and Space Museum, Washington DC. North American X-15A-2, serial number 56-6671, is at the United States Air Force Museum, Wright-Patterson AFB, Ohio. X-15-3, serial number 56-6672, crashed on 15 November 1967, resulting in the death of Maj. Michael J. Adams.

Title F-8 DFBW simulating STS contro l system - Pilot-induced oscillation (PIO) on landing
Description From 1972 to 1985 the NASA Dryden Flight Research Center conducted flight research with an F-8C employing the first digital fly-by-wire flight control system without a mechanical back up. The decision to replace all mechanical control linkages to rudder, ailerons, and other flight control surfaces was made for two reasons. First, it forced the research engineers to focus on the technology and issues that were truly critical for a production fly-by-wire aircraft. Secondly, it would give industry the confidence it needed to apply the technology--confidence it would not have had if the experimental system relied on a mechanical back up. In the first few decades of flight, pilots had controlled aircraft through direct force--moving control sticks and rudder pedals linked to cables and pushrods that pivoted control surfaces on the wings and tails. As engine power and speeds increased, more force was needed and hydraulically boosted controls emerged. Soon, all high-performance and large aircraft had hydraulic-mechanical flight-control systems. These conventional flight control systems restricted designers in the configuration and design of aircraft because of the need for flight stability. As the electronic era grew in the 1960s, so did the idea of aircraft with electronic flight-control systems. Wires replacing mechanical devices would give designers greater flexibility in configuration and in the size and placement of components such as tail surfaces and wings. A fly-by-wire system also would be smaller, more reliable, and in military aircraft, much less vulnerable to battle damage. A fly-by-wire aircraft would also be much more responsive to pilot control inputs. The result would be more efficient, safer aircraft with improved performance and design. The Aircraft By the late 1960s, engineers at Dryden began discussing how to modify an aircraft and create a fly-by-wire testbed. Support for the concept at NASA Headquarters came from Neil Armstrong, former research pilot at Dryden. He served in the Office of Advanced Research and Technology following his historic Apollo 11 lunar landing and knew electronic control systems from his days training in and operating the lunar module. Armstrong supported the proposed Dryden project and backed the transfer of an F-8C Crusader from the U.S. Navy to NASA to become the Digital Fly-By-Wire (DFBW) research aircraft. It was given the tail number "NASA 802." Wires from the control stick in the cockpit to the control surfaces on the wings and tail surfaces replaced the entire mechanical flight-control system in the F-8. The heart of the system was an off-the-shelf backup Apollo digital flight-control computer and inertial sensing unit, which transmitted pilot inputs to the actuators on the control surfaces. On May 25, 1972, the highly modified F-8 became the first aircraft to fly completely dependent upon an electronic flight-control system without any mechanical backup. The pilot was Gary Krier. The first phase of, the DFBW program validated the fly-by-wire concept and quickly showed that a refined system, especially in large aircraft, would greatly enhance flying qualities by sensing motion changes and applying pilot inputs instantaneously. The Phase 1 system had a backup analog fly-by-wire system in the event of a failure in the Apollo computer unit, but it was never necessary to use the system in flight. In a joint program carried out with the Langley Research Center in the second phase of research, the original Apollo system was replaced with a triply redundant digital system. It would provide backup computer capabilities if a failure occurred. The DFBW program lasted 13 years. The final research flight, the 210th of the program, was made April 2, 1985, with Dryden Research Pilot Ed Schneider at the controls. Research Benefits The F-8 DFBW validated the principal concepts of the all-electric flight control systems now used in a variety of airplanes ranging from the F/A-18 to the Boeing 777 and the space shuttles. A DFBW flight control system also is used on the space shuttles. NASA 802 was the testbed for the sidestick-controller used in the F-16 fighter, the second U.S. high performance aircraft with a DFBW system. In addition to pioneering the space shuttle's fly-by-wire flight-control system, NASA 802 was the testbed that explored Pilot Induced Oscillations (PIO) and validated methods to suppress them. PIOs occur when a pilot over-controls an aircraft and a sustained oscillation results. On the last of five free flights of the prototype Space Shuttle Enterprise during approach and landing tests in l977, a PIO developed as the vehicle settled onto the runway. The problem was duplicated with the F-8 DFBW and a series of PIO suppression filters was developed and tested on the aircraft for the shuttle program office. DFBW research carried out with NASA 802 at Dryden is now considered one of the most significant and successful aeronautical programs in NASA history. In this clip we see NASA research pilot John Manke at the controls of Dryden's F-8 Digital Fly-By-Wire aircraft as it enters a severe pilot induced oscillation or PIO just after completion of a touch-and-go landing while testing for a signal-delay-related problem that occurred during an approach to landing on the shuttle prototype Enterprise.

Title F5D-1 on ramp with Neil Armstrong preparing to fly a Dyna-Soar simulation
Description The Douglas F5D-1 Skylancer being pre-flighted by the pilot while the crew chief prepares to pull the wheel chocks on the "hot gun" ramp at Edwards Air Force Base, California. The aircraft was one of two prototype F5D-1s obtained by NASA Flight Research Center in 1961. The F5D-1 Skylancer (Bu. No. 142350) had a red and white paint pattern with a NASA identification number of 213 which later became NASA 708. The Douglas F5D-1 Skylancer was built by the Navy as an all-weather fighter interceptor that never made the jump to production. Four test aircraft were developed with the same basic airframe as the Douglas F4D Skyray. With increasing modifications the four aircraft were re-designated F5D-1s before their first flights. Future Astronaut Neil Armstrong was one of the NASA research pilots assigned to support duties for the Dyna-Soar program. In addition to working at the Boeing facility in Washington state, Armstrong also tested the Dyna-Soar launch abort profile using this F5D-1, which had a similar wing shape to the Dyna-Soar. The aircraft arrived at the Flight Research Center on June 15, 1961. After the Dyna-Soar program was cancelled in December 1963, this F5D-1 continued to be used, serving as a flying simulator for the M2-F2 and as a chase plane for lifting-body flights (providing the lifting-body pilot with an extra set of eyes to assist in emergencies and avert potential crashes) This F5D-1 left the Flight Research Center (later designated the Dryden Flight Research Center) on May 19, 1970, and was donated to the Neil A. Armstrong Museum in Wapakoneta, Ohio.
