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. |
