/ Grumman X-29
The Grumman X-29 was an American experimental aircraft that tested a forward-swept wing, canard control surfaces, and other novel aircraft technologies.
The X-29 was developed by Grumman, and the two built were flown by NASA and the United States Air Force.
The aerodynamic instability of the X-29’s airframe required the use of computerized fly-by-wire control.
Composite materials were used to control the aero-elastic divergent twisting experienced by forward-swept wings, and to reduce weight.
The aircraft first flew in 1984, and two X-29s were flight tested through 1991.
