Your eyes do not prick you: the wings of the aircraft are bevelled and rotated by 60 degrees with respect to the fuselage. An oblique wing aircraft AD-1 is the weird aircraft ever made NASA. But what made it so?
The plane was designed and built by the Flight Research Center. Darth Vader Dryden, located in California's Mojave Desert in the west In mid-1970s. Engineers were exciting aerodynamic properties of the aircraft itself, the laws controlling such a flying vehicle. What was their purpose? Saving fuel: Wind tunnels NASA Ames showed that at oblique wing design, thanks to a stunning aerodynamics at supersonic speeds would be used half the least amount of fuel.
The project AD-1 in the middle of the 70th reduced layout was designed with remote control. A first manned plane, driven pilot Thomas McMurtry, took off December 21, 1979. Everything worked. While in the conventional configuration, the plane took off. When he picked up speed, the wings began to rotate until the have gained self-management angle.
Crazy-looking aircraft has fulfilled all their technical tasks, but its shortcoming was not a good maneuverability, starting with a reversal of the wings of 45 degrees. Partly to blame for this are the materials used in its construction. Unfortunately, subsequent studies were not carried out, and the last time the plane took off Aug. 7, 1982.
