MULTI ANGLE JOINT PLAIN FLAP FOR AERIAL VEHICLE

摘要

The articulated rotatable flat flap for a small aircraft according to the present invention is mounted on one side of the aircraft wing in a diffractive state so that the diffraction angle is adjusted by a separate driving device to increase or lift the lift of the wing during takeoff and landing of the aircraft. In a flat flap of an aircraft intended to increase the lift ratio of the lift coefficient,;The flat plate flap is formed of a multi-joint flat flap connected by at least two hinge portions, the multi-joint flat flap, the multi-stage diffraction is simultaneously performed by a power transmission device driven by an actuator for linear reciprocating motion as a power source Characterized in that made.;According to the present invention, since the articulated flat flap is driven simultaneously by a power transmission device consisting of one actuator, a sprocket, and a drive chain, the structure is simple and the built-in design in which the driving device is not exposed to the outside is possible. There is an effect that can lower the unit price.;In addition, the present invention, by varying the gear ratio between the chain and the sprocket to implement a variety of diffraction angles, it is possible to greatly increase the diffraction angles throughout the main wing to improve the lift coefficient, high-performance aircraft on small aircraft wings The effect is to have a multi-level flap function similar to that in.
