Supersonic Flying Wing Nabs $100,000 from NASA | Bidirectional Flying Wing Aircraft | Innovationnewsdaily.com: Zha's bidirectional flying wing kicks the general concept up a notch by essentially laying two flying wings on top of one another at a 90 degree angle, so that the aircraft faces one way for subsonic flight and rotates another way for supersonic flight.

The midair transformation allows the aircraft to fly in its most fuel-efficient modes at both subsonic and supersonic speeds, Zha explained. Jet engines located on top of the aircraft in concept illustrations appear to rotate independently of the aircraft so that they can always point forward in flight.
