  • The X-29 was not the first FSW, the first was made in 1944 by Junkers, called the Junkers Ju-287.
  • 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 aeroelastic divergent twisting experienced by forward-swept wings, and to reduce weight. The X-29 first flew in 1984; two X-29s were flight tested over the next decade.
  • The Grumman X-29 is an experimental fighter, with forward swepted wings, based on the F-5. Some parts of it, for example the fuselage, are taken from the F-5 Tiger (actually from the single engine F-20, a derivative of the F-5). To save money, parts of the F-16 Fighting Falcon and F/A-18 Hornet were also used. For emergency situations it is equipped with a drogue parachute. On the inlets, canards, like on the Eurofighter Typhoon, are monted and behind of them are the forward swepted wings. The Russian equal to the X-29 is the Sukhoi Su-47 Berkut.

abstract
  • The Grumman X-29 is an experimental fighter, with forward swepted wings, based on the F-5. Some parts of it, for example the fuselage, are taken from the F-5 Tiger (actually from the single engine F-20, a derivative of the F-5). To save money, parts of the F-16 Fighting Falcon and F/A-18 Hornet were also used. For emergency situations it is equipped with a drogue parachute. On the inlets, canards, like on the Eurofighter Typhoon, are monted and behind of them are the forward swepted wings. The advantages of forward swepted wings are the better agility, higher angles of attack, beacause of more buoyancy and a lower stall speed than on most of the other aircraft. The Russian equal to the X-29 is the Sukhoi Su-47 Berkut.
  • The X-29 was not the first FSW, the first was made in 1944 by Junkers, called the Junkers Ju-287.
