Abstract
A flap mounted on a tapered main wing of an aircraft, is supported by at least two link units. The link units are formed into analogous shapes with an analogous size ratio equal to the ratio between corresponding chord lengths of the main wing. As a result, the amounts of protrusion of the flap are varied in the span direction in accordance with the analogous size ratio, and the flap performs a three-dimensional motion such that it is moved in the span direction while being retracted and lowered. Thus, the flap can be moved to protrude to an optimal position and through an optimal angle according to the chord lengths of the main wing. When the flap is a slotted flap, an appropriate slot width can be ensured at each of the portions in the span direction, whereby the aerodynamic characteristic of the flap mounted on the tapered main wing can be uniform in the span direction.
