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]

2015年11月5日 · The X-29 program did demonstrate several new technologies as well as new uses of proven technologies including aeroelastic tailoring to control structural divergence and use of a relatively large, close-coupled canard for longitudinal control.

2019年7月13日 · The X-29, an experimental plane flown by NASA in the 1980s, sports one of the most unusual designs in the history of aviation.

2014年2月14日 · This look-down view of the X-29 research aircraft in flight over California’s Mojave Desert during the 1980s and 1990s shows its striking and unique forward swept wing and canard design.

The December 14, 1984, test flight of the X-29—the most aerodynamically unstable aircraft ever built—demonstrated forward-swept wing technology for supersonic fighter aircraft for the first time.

2016年2月10日 · On Dec. 13, 1985, the X-29 became the first forward-swept-wing airplane in the world to exceed Mach 1 in level flight, and flight results showed that a highly unstable aircraft with forward-swept wings could be flown safely with excellent maneuverability and high G-loads.

2023年11月19日 · Without flying a single combat mission, the X-29 has become a part of military aviation history for its bold development of new technologies, some of which informed the design of many of the jets...

The X-29A is 35% statically unstable longitudinally and is controllable only through the use of an advanced, digital fly-by-wire flight control system (FCS). The predicted aerodynamic advantages of the X-29A configuration are what make the risk of deve-loping and flying a new airplane worthwhile. It is, therefore, imperative that the wing ...

2000年2月3日 · The X-29, featuring one of the most unusual aircraft designs in aviation history, was flown by the NASA Dryden Flight Research Center, Edwards, California, as a technology demonstrator to investigate a host of advanced concepts and technologies.

2025年3月3日 · Key Points and Summary: The experimental X-29 aircraft, developed by NASA, DARPA, and Grumman in the 1980s, featured innovative forward-swept wings designed to achieve improved maneuverability and a higher angle of attack.
