• Variable-incidence wing — A variable incidence wing has an adjustable angle of incidence in order to reduce landing and take off distances. It was patented on March 20, 1912 (patent #444010) in Paris by Bulgarian inventor Georgi Bojinov.The necessary components add extra… …   Wikipedia

• variable-incidence wing — A wing with a variable rigging angle of incidence that is controlled by the pilot. Such a wing permits increases in angles of attack without a corresponding nose high attitude, thus improving visibility on takeoff and landing. Two positions of… …   Aviation dictionary

• variable-incidence tailplane — The tailplane or the horizontal stabilizer, used either by itself or in addition to a trimming tab, in which the incidence can be varied to balance out of trim forces. This arrangement is more effective than trim tabs at high Mach numbers. Its… …   Aviation dictionary

• Variable camber wing — is a design of aircraft wing by V.J. Burnelli that changes the camber of the airfoil (1933), and varies the area and camber of the wing (1937).This is depicted in the figure below. A mechanism moves and rotates the leading and trailing edge to… …   Wikipedia

• Variable-sweep wing — A Variable sweep wing is an aeroplane wing that may be swept back and then returned to its original position during flight. It allows the aircraft s planform to be modified in flight, and is therefore an example of variable geometry.Typically, a… …   Wikipedia
