Radical bi-directional flying wing design gets NASA fundingSubmitted by Bob-45 on Thu, 10/04/2012 - 14:01

A team that has created a supersonic jet design resembling a flying shuriken has been awarded a US$100, 000 grant from NASA’s Innovative Advanced Concepts (NIAC) program to continue development of the aircraft. Aside from looking suitably futuristic, the concept plane’s four-pointed star design serves a practical purpose. By rotating in mid air, the plane can transition between broad-wing subsonic and shorter wingspan supersonic configurations.

Aircraft design is usually a compromise between subsonic and supersonic performance. At low speeds, broad wings provide more lift and help minimize takeoff distance, while swept back wings with a smaller profile enhance performance at high speeds. Variable-sweep wing (or swing wing) aircraft, such as the F-14 Tomcat and B-1 Lancer, get around this with wings that are spread broadly at takeoff and low speeds and can be swept back while in flight for improved performance at high speeds.
