| Photo Description |
NASA F-15B #836 landing with Quiet Spike attached. The project seeks to verify the structural integrity of the multi-segmented, articulating spike attachment designed to reduce and control a sonic boom. |
| Project Description |
Gulfstream Aerospace and NASA's Dryden Flight Research Center are testing the structural integrity of a telescopic 'Quiet Spike' sonic boom mitigator on a NASA F-15B testbed aircraft. The Quiet Spike was developed as a means of controlling and reducing the sonic boom caused by an aircraft ?breaking? the sound barrier. Made of advanced composite materials, the Quiet Spike weighs some 470 pounds and extends from 14 feet in subsonic flight to 24 feet in supersonic flight. Since March 2004, when Gulfstream was awarded a patent for the Quiet Spike, the device has been through extensive ground testing, including wind-tunnel testing, to arrive at the point where it could be installed on an F-15B aircraft and flown. The F-15B is capable of flying at speeds in excess of Mach 2.0, or two times the speed of sound. Once the Quiet Spike has proven to be structurally sound, it can be incorporated with confidence onto advanced low-boom configuration aircraft to further control and mitigate adverse acoustic impacts of supersonic flight. The hope is for the Quiet Spike to become an important means of changing the traditional N-wave sonic boom into smooth and more rounded pressure waves, shaped roughly like a sine wave or a sideways "S." This change in the wave shape results in a softer sound that is quieter than the Concorde sonic boom by a factor of 10,000. |

| Project Description |
NASA's Intelligent Flight Control System (IFCS) project, utilizing NASA Dryden's highly modified F-15B, tail number 837, focuses on development of "self-learning" neural network software for aircraft flight control computers. Such a revolutionary flight control system could enable future aircraft that sustain major system failures or combat damage to be flown to a safe, controlled landing. The current series began on Dec. 6, 2002. The F-15B formerly flew in the Advanced Control Technology for Integrated Vehicles (ACTIVE) project at Dryden from 1995 through 1999. |

| Project Description |
ACTIVE employs thrust-vectoring of engine exhaust and an advanced control system to develop technology to improve cruise and maneuvering capabilities of future aircraft at both subsonic and supersonic speeds. The ACTIVE F-15B (Serial #71-0290) incorporates engine exhaust nozzles developed by Pratt and Whitney which can vector up to 20 degrees in both pitch and yaw, along with close-coupled canards ahead of the wings, to improve performance and maneuvering ability. |
