Northrop Grumman Corp. will design a supersonic experimental aircraft that employs a wing that varies position for most efficient flight performance under a $10.3 million contract from the Pentagon's Defense Advanced Research Projects Agency. The oblique flying wing program aims to design and conduct the first-ever flight tests of a tailless, supersonic, variable sweep oblique flying wing... In an oblique wing aircraft, one wing of the aircraft is swept forward and the other backward in an asymetrical configuration, which varies with flight speed. The wing, also known as a "scissors wing," pivots over a center point, shifting angle as the...
