While the ST Aero MAV-1 is a low observable Unmanned Air Vehicle prototype developed between ST Aerospace and Defence Science and Technology Agency, what is designed to avoid detection using a variety of technologies that reduce reflection/emission of radar, infrared, visible light, radio-frequency (RF) spectrum, and audio?
ST Aero MAV-1 The MAV-1 (Maneuvering Air Vehicle) is a low observable Unmanned Air Vehicle prototype developed between ST Aerospace and Defence Science and Technology Agency for its swarming unmanned air vehicle research programme. The prototype was unveiled in Asian Aerospace 2004 and the first test flight was reported in 2005.
Quiet Supersonic Technology The Quiet Supersonic Technology, also known as QueSST is a project in development by NASA and Lockheed Martin that is aimed to be a quieter replacement for the Concorde. After design review, the next stage is to test models in a wind tunnel. The ground noise is expected to be around 60 dB(A), about 1000 times quieter than current supersonic aircraft. This is achieved by using a long, narrow airframe and canards to keep the shock waves from coalescing.
