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.
Flaps raise the maximum lift coefficient of the aircraft and therefore reduce its stalling speed. [5] They are used during low speed, high angle of attack flight including take-off and descent for landing. Some aircraft are equipped with "flaperons", which are more commonly called "inboard ailerons" [citation needed]. These devices function ...
An aircraft is streamlined from nose to tail to reduce drag making it advantageous to keep the sideslip angle near zero, though an aircraft may be deliberately "sideslipped" to increase drag and descent rate during landing, to keep aircraft heading same as runway heading during cross-wind landings and during flight with asymmetric power.
The speed will vary among aircraft types and varies according to factors such as aircraft weight, runway length, wing flap setting, engine thrust used and runway surface contamination; thus, it must be determined by the pilot before takeoff.
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.
The term chord is also applied to the width of wing flaps, ailerons and rudder on an aircraft. The term is also applied to compressor and turbine aerofoils in gas turbine engines such as turbojet, turboprop, or turbofan engines for aircraft propulsion. Many wings are not rectangular, so they have different chords at different positions.

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.
