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.

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...

2014年2月9日 · Research results showed that the configuration of forward-swept wings, coupled with movable canards, gave pilots excellent control response at up to 45 degrees angle of attack, higher than comparable fighter aircraft. During its flight history, X …

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.

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 ...

This document examines the goals and accomplishments of the forward sweep-winged X-29.

2020年10月30日 · Packed with cutting-edge features, the Grumman X-29 was one of the most innovative fighters of its time—today, its legacy is confined largely to the museum.
