The NASA Oblique Wing Research Aircraft, the predecessor to the AD-1. The first known oblique wing design was the Blohm & Voss P.202, proposed by Richard Vogt in 1942. [1] The oblique wing concept was later promoted by Robert T. Jones, an aeronautical engineer at NASA's Ames Research Center, Moffett Field, California.
Oblique wing on a NASA AD-1. An oblique wing (also called a slewed wing) is a variable geometry wing concept. On an aircraft so equipped, the wing is designed to rotate on center pivot, so that one tip is swept forward while the opposite tip is swept aft.

After being used to qualify the 737 design, NASA heavily modified the aircraft for continuing research. Boeing 747-100SR. Fixed Wing Shuttle Carrier Aircraft ...
This initial oblique-wing program, which ran from 1976 through 1982, was a joint effort between NASA’s Ames Research Center and Dryden Flight Research Center, CA, thus giving rise to the aircraft’s name: Ames-Dryden AD-1 Oblique Wing Research Aircraft.

A fixed-wing aircraft may have more than one wing plane, stacked one above another: Biplane: two wing planes of similar size, stacked one above the other.The biplane is inherently lighter and stronger than a monoplane and was the most common configuration until the 1930s.
The wing ribs were also made of epoxy and carbon fiber. Shaped Styrofoam was used for the wing's leading edge and a durable clear plastic film covered the entire wing. [1] The Helios Prototype shared the same 8-foot (2.4 m) wing chord (distance from leading to trailing edge) as its Pathfinder and Centurion predecessors.
The chine lift increases with the square of the Mach number, helping counterbalance the rearward shift in the lift of the main wing in supersonic conditions. If a tailless (Delta) wing is trimmed for safe subsonic flight, at high speeds it gains excess trim drag in pitch and becomes excessively stable resulting in poor manoeuvrability. The ...
