One problem with the forward-swept design is that when a swept wing yaws sideways (moves about its vertical axis), one wing retreats while the other advances. On a forward-swept design, this reduces the sweep of the rearward wing, increasing its drag and pushing it further back, increasing the amount of yaw and leading to directional instability.
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]
A disadvantage of such a forward-swept wing design is that it twists when under load, resulting in greater stress on the wing than occurs with a similar straight or aft-swept wing. [9] This requires the wing be designed to twist as it bends—opposite to the geometric twisting. [10] This is done by the use of composite wing skins laid-up to twist.
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 ...
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.
Forward-swept wings can also experience dangerous flexing effects compared to aft-swept wings that can negate the tip stall advantage if the wing is not sufficiently stiff. In aft-swept designs, when the airplane maneuvers at high load factor the wing loading and geometry twists the wing in such a way as to create washout (tip twists leading ...
The Mistral is a biplane of mixed wooden and composite construction, with forward swept wings, with the all-moving lower wings used as large ailerons, and a conventional, all-moving tailplane. It has a fixed tricycle landing gear and a nose-mounted Rotax piston engine. The Mistral has an enclosed cockpit with two side-by-side seats forward of ...
