Explore: Sweep Angle

Backwards sweep causes the tips to reduce their angle of attack as they bend, reducing their lift and limiting the effect. Forward sweep causes the tips

variable-sweep wing allows the pilot to use the optimum sweep angle for the aircraft's speed at the moment, whether slow or fast. The more efficient sweep angles

sharp leading-edge airfoil. More information is available here. The sweep angle of the flow to a blade element for a helicopter in forward flight can

extinguish the fire. Chimneys with sharp angles posed a particular hazard. These boys were apprenticed to the sweep, and from 1778 until 1875 a series of

delta wing. The sweep angle on the leading edge is 57° with a TsAGI S-12 airfoil. The angle of incidence is 0° while the dihedral angle is −2°. On the

is swept forward while the opposite tip is swept aft. By changing its sweep angle in this way, drag can be reduced at high speed (with the wing swept)

leading-edge slots, wing fences and related devices. With a large enough angle of rearward sweep, in the transonic to low supersonic speed range the wing's leading

prototype was that the sweep angle of the wings could be changed before flight, a feature further developed in later variable-sweep aircraft such as the

elements (such as wing sweep, vertical mount point of the wing, etc.) may be more difficult to change than the dihedral angle. As a result, differing

supersonic flight. The wings have a leading-edge kink, resulting in two sweep angles. The fighter is large in size, with a thin and wide nose area, cockpit
