A flap is a high-lift device used to reduce the stalling speed of an aircraft wing at a given weight. Flaps are usually mounted on the wing trailing edges of a fixed-wing aircraft. Flaps are used to reduce the take-off distance and the landing distance. Flaps also cause an increase in drag so they are retracted when not needed.
The high-lift Fowler flap is located on the trailing edge of an airplane wing which increases wing area, lift, and drag. [4] The flap often forms part of the upper surface of the wing similar to a plain flap or a split flap, but upon extension it slides rearward before lowering. Fowler flaps always feature one or more slots.
In aircraft design and aerospace engineering, a high-lift device is a component or mechanism on an aircraft's wing that increases the amount of lift produced by the wing. The device may be a fixed component, or a movable mechanism which is deployed when required. Common movable high-lift devices include wing flaps and slats.
The wings of a fixed-wing aircraft are not necessarily rigid; kites, hang gliders, variable-sweep wing aircraft and airplanes that use wing morphing are all examples of fixed-wing aircraft. Flange – Flap – is a high-lift device used to reduce the stalling speed of an aircraft wing at a given weight.
Krueger flaps, or Krüger flaps, are lift enhancement devices that may be fitted to the leading edge of an aircraft wing. Unlike slats or droop flaps, the main wing upper surface and its leading edge is not changed. Instead, a portion of the lower wing is rotated out in front of the main wing leading edge.
The Federal Aviation Administration on Sunday said it will launch an investigation after the engine cowling of a Southwest Airlines plane fell off during takeoff in Denver and struck the wing flap.

Ball-Bartoe Jetwing used for blown-wing research. Note the "augmentor", intended to direct the discharged airflow over the wingWilliams [8] states some flap blowing tests were done at the Royal Aircraft Establishment before the Second World War, and that extensive tests were done during the war in Germany including flight tests with Arado Ar 232, Dornier Do 24 and Messerschmitt Bf 109 aircraft.
