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 very first Wright Flyer I was a biplane.
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.
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.
The wings are longer than the ones on previous versions of that airplane—a design change that helps increase the craft’s overall fuel efficiency. NASA’s weird wing design could lead to ...
The Grumman X-29 is an American experimental aircraft that tested a forward-swept wing, canard control surfaces, and other novel aircraft technologies. Funded by NASA, the United States Air Force and DARPA, the X-29 was developed by Grumman, and the two built were flown by NASA and the United States Air Force. [1]

ESAero is the prime contractor responsible for system integration and instrumentation, while Joby is responsible for design and manufacture of the electric motors, propellers, and carbon fiber wing section. [11] In 2015, NASA researchers were ground testing a 31 ft (9.4 m) span, carbon composite wing section with 18 electric motors powered by ...
The Helios Prototype is an ultra-lightweight flying wing aircraft with a wingspan of 247 feet (75 m), longer than the wingspans of the U.S. Air Force C-5 military transport (222 feet (68 m) or the Boeing 747 (195 or 224 feet (59 or 68 m), depending on the model), the two largest operational aircraft built in the United States.
