Forward-swept wings designs, some whose design had begun during the prewar period, were developed during World War II, independently in Germany, the Soviet Union, Japan, and the United States. An early example to fly, in 1940, was the Soviet Belyayev DB-LK, a twin-boom design with forward-swept outer wing sections and backwards-swept tips. It ...
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]
The Sukhoi Su-47 being followed by two Su-27s.The Su-47 uses a forward wing sweep, while the Su-27s sport a more conventional backward-swept design.. A swept wing is a wing angled either backward or occasionally forward from its root rather than perpendicular to the fuselage.
The Junkers Ju 287 was a multi-engine tactical jet bomber built in Nazi Germany in 1944. It featured a novel forward-swept wing, and the first two prototypes (which were aerodynamic testbeds for the production Ju 287) were among the very few jet propelled aircraft ever built with fixed landing gear.
A variable-sweep wing, colloquially known as a "swing wing", is an airplane wing, or set of wings, that may be modified during flight, swept back and then returned to its previous straight position. Because it allows the aircraft's shape to be changed, it is a feature of a variable-geometry aircraft.
The HFB 320 Hansa Jet is a twin-engine, ten-seat business jet that was designed and produced by German aircraft manufacturer Hamburger Flugzeugbau between 1964 and 1973. The most recognisable and unconventional feature of the aircraft is its forward-swept wing.
Forward swept: the wing angles forward from the root. Benefits are similar to backwards sweep, also it avoids the stall problems and has reduced tip losses allowing a smaller wing, but requires even greater stiffness to avoid aeroelastic flutter as on the Sukhoi Su-47 .
The SR-10 is a mid-wing monoplane of all-composite construction, with a wing swept forward at an angle of 10 degrees. The crew of two sit in a tandem cockpit. The crew of two sit in a tandem cockpit. It is powered by a single turbofan, with an Ivchenko AI-25 V AI25TSR (modification of AI25TL) fitted in the prototype, but more modern Russian ...
