Abstract: The present invention provides an aircraft including: a main wing; and a flight control surface that is deployed from the main wing in a first direction and in a second direction different from the first direction. In the aircraft, an end surface of the flight control surface facing the main wing when the flight control surface is not deployed is inclined with respect to the first direction or the second direction on at least one side of a longitudinal direction of the flight control surface, and a portion of the main wing facing the end surface is also inclined with respect to the first direction or the second direction in accordance with the end surface.

Abstract: The flap deploying device for a flap disposed at a leading edge or a trailing edge of a main wing of the aircraft, the deploying device including: a drive source; a moving mechanism with a moving body advancing and retracting by power of the drive source; a carriage mechanism that carries advancing and retracting motion of the moving body to the flap so as to deploy the flap between a retracted position and a deployed position; and a rail that guides the carriage mechanism. Since the moving mechanism is arranged lateral to the rail in the wingspan direction of the main wing, the dimension of the wing in a thickness direction can be reduced at least by a dimension corresponding to the moving mechanism. Therefore, the wing can be made thinner, or the projecting height of a flap track fairing can be reduced.

Abstract: To provide an actuator device for a flight control surface which can reduce a stress applied to the flight control surface when one of two actuators is operated. The present invention relates to a hydraulically-operated actuator device 30 which drives a flight control surface of an aircraft 1, including a first actuator 31A that is provided with a first piston rod 39A, and drives an aileron body 11; a second actuator 31B that is provided with a second piston rod 39B, and drives the aileron body 11 when the function of the first actuator 31A is lost or reduced; and a single second connection fitting 41 to which the first piston rod 39A and the second piston rod 39B are both connected, wherein the first actuator 31A and the second actuator 31B are connected to the aileron body 11 via the second connection fitting 41.

Abstract: The present invention includes: a slat 3; and a position adjustment mechanism that adjusts an attachment position of the slat 3 to a main wing 1 by causing the slat 3 to swing, the position adjustment mechanism including: a pivot shaft S1 as a center of the swing motion of the slat 3; and a driving shaft S2 that is rotatably supported on a rail 12, and induces the swing motion of the slat 3. The driving shaft S2 includes: a main shaft 30 that causes the slat 3 to swing by acting thereon; an inner-side eccentric bushing 31 that is fixed to the main shaft 30, and eccentric with respect to the main shaft 30; and an outer-side eccentric bushing 32 that is eccentric with respect to the inner-side eccentric bushing 31, rotatably arranged therearound, and supported rotatably with respect to the rail 12.
