| Project Description |
The remotely-piloted Altair unmanned aerial vehicle (UAV) was developed by General Atomics Aeronautical Systems, Inc., (GA-ASI) for NASA under NASA's Environmental Research Aircraft and Sensor Technology (ERAST) project. NASA is using the Altair as a long-endurance, high-altitude platform for development of UAV technologies and environmental science missions. As a technology demonstrator, Altair will help validate a variety of command and control technologies for UAVs, including over-the-horizon control, collision-avoidance and other technologies required to enable UAVs to operate safely and routinely with other aircraft in the national airspace. It is also being used to demonstrate the capabilities of UAVs to conduct missions related to Earth Science, disaster management, homeland security and law enforcement. The Altair took to the air on its first checkout flight on June 9, 2003 at El Mirage, California. The Altair is a modified version of GA-ASI's MQ-9 Predator B unmanned aerial vehicle (UAV) that was developed for the U.S. Air Force. Differences from the military aircraft include a longer wingspan to enable the Altair to sustain higher altitudes, a triplex redundant flight control system and modified avionics and electronics to support its civil missions. It is flown by a pilot from a ground control station, with flight commands and data relayed to and from the aircraft via either a satellite communications link or by direct radio link. The Altair also has full Global Positioning System (GPS) capability to assist in navigation. The Altair is designed to carry a 700-lb. payload of instruments and imaging equipment in its forward fuselage payload bay for as long as 32 hours at up to 52,000 feet altitude. It can also carry up to 3,000 pounds of payload externally at lower altitudes and for shorter durations. Eleven-foot extensions on each wing give the Altair an overall wingspan of 86 feet with an aspect ratio of 23. Built almost entirely of composite materials, Altair is powered by a 700-hp. rear-mounted Honeywell TPE-331-10 turboprop engine, driving a three-blade propeller. It has a maximum gross takeoff weight of 7,400 lbs, including 3,000 lbs of fuel. Following successful completion of basic airworthiness flight tests in 2003, Altair is currently being leased by NASA for a five-year period and is scheduled to eventually be acquired by NASA to serve as an aerial platform to support the aerospace agency's suborbital science program. |

Proteus aircraft low-level flyby at Las Cruces Airport. |
| Project Description |
The Proteus is a unique aircraft, designed as a high-altitude, long-duration telecommunications relay platform with potential for use on atmospheric sampling and Earth-monitoring science missions. Designed by Burt Rutan, president of Scaled Composites, LLC, of Mojave, Calif., Proteus is an "optionally piloted" aircraft ordinarily flown by two pilots in a pressurized cabin. However, it also has the capability to perform its missions semi-autonomously or flown remotely from the ground. The aircraft is designed to cruise at altitudes from 59,000 to more than 65,000 feet for up to 18 hours. It was designed to carry an 18-foot diameter telecommunications antenna system for relay of broadband data over major cities. The design allows Proteus to be reconfigured for a variety of other missions such as atmospheric research, reconnaissance, commercial imaging, and launch of small space satellites. It is designed for extreme reliability and low operating costs, and to operate out of general aviation airports with minimal support. Proteus has an all-composite airframe with graphite-epoxy sandwich construction. Its wingspan of 77 feet 7 inches is expandable to 92 feet with removable wingtips installed. Proteus is 56.3 feet long, 17.6 feet high and weighs 5,900 pounds empty. Proteus is powered by two Williams FJ44-2 turbofan engines, each rated at 2,300 pounds of thrust. Flight testing of the Proteus began in the summer of 1998 at Mojave Airport and continued through the end of 1999. Under NASA's Environmental Research Aircraft and Sensor Technology (ERAST) project, NASA's Dryden Flight Research Center assisted Scaled Composites in developing a sophisticated station-keeping autopilot system and a satellite communications (SATCOM)-based uplink-downlink data system for Proteus' performance and payload data. Flight testing included the installation and checkout of the autopilot system, including the refinement of the altitude hold and altitude change software. The SATCOM equipment, including avionics and antenna systems, was installed and checked out in several flight tests. The systems performed flawlessly during Proteus' deployment to the Paris Airshow in 1999. NASA has used Proteus as a testbed for a variety of technologies related to maturing unmanned air vehicles (UAVs) for use in civil applications. A small Airborne Real-Time Imaging System (ARTIS) camera, developed by HyperSpectral Sciences, Inc., under NASA's ERAST project, was demonstrated during the summer of 1999 when it took visual and near-infrared photos from Proteus while it was flying high over the Experimental Aircraft Association's "AirVenture 99" Airshow at Oshkosh, Wisc. The images were displayed on a computer monitor at the show only moments after they were taken. In March 2002, NASA Dryden, in cooperation with New Mexico State University's Technical Analysis and Applications Center (TAAC), the FAA and several other entities, conducted flight demonstrations of an active detect, see, and avoid (DSA) system for potential application to unmanned aerial vehicles (UAVs) out of Las Cruces, New Mexico. Proteus was flown as a surrogate UAV controlled remotely from the ground, although safety pilots were aboard to handle takeoff and landing and any potential emergencies. Three other aircraft, ranging from general aviation aircraft to a NASA F/A-18, served as "cooperative" target aircraft with an operating transponder. In each of 18 different scenarios, a Goodrich Skywatch HP Traffic Advisory System (TAS) on the Proteus detected approaching air traffic on potential collision courses, including several scenarios with two aircraft approaching from different directions. The remote pilot then directed Proteus to turn, climb or descend as needed to avoid the potential threat. In April 2003, a second series of flight demonstrations focusing on "non-cooperative" aircraft (those without operating transponders), was conducted in restricted airspace near Mojave, Calif., again using the Proteus as a surrogate UAV. Proteus was equipped with a small Amphitech OASys 35 Ghz primary radar system to detect potential intruder aircraft on simulated collision courses. The radar data was telemetered directly to the ground station as well as via an Inmarsat satellite system installed on Proteus. A mix of seven intruder aircraft, ranging from a sailplane to a high-speed jet, flew 20 scenarios over a four-day period, one or two aircraft at a time. In each case, the radar picked up the intruding aircraft at ranges from 2.5 to 6.5 miles, depending on the intruder's radar signature. Proteus' remote pilot on the ground was able to direct Proteus to take evasive action if needed. Based on the preliminary results of both series of tests, project engineers believe that some upgrades would have to be made to both the Skywatch and the OASys detection systems to maximize their effectiveness as collision-avoidance detection sensors for UAVs. Additional flight tests of other types of detection systems, such as electro-optical infrared devices, may occur in the future under a follow-on program in an effort to establish an equivalent level of safety for UAVs to that now required of manned aircraft. The ERAST Project is sponsored by the Office of Aerospace Technology at NASA Headquarters, and is managed by the Dryden Flight Research Center, Edwards, Calif. |
