Device for adjusting camber angle of V-shaped empennage

Abstract

A device for adjusting the camber angle of a V-shaped empennage is characterized in that a central connecting piece is positioned at the center of the adjusting device, and an empennage connecting rod on the central connecting piece is fixedly connected with the rotating shaft of the empennage; two guiding rails are respectively positioned at two sides of the central connecting piece and parallel to each other; four motors are symmetrically fixed on motor installation plates on the central connecting piece; four gears are divided into two groups, and the gears of each group are engaged with the inner surface of one guiding rail; the four gears are respectively fixed on the output shafts of the motors; the center lines of the motors at a same side parallel to each other and are positioned in a same horizontal plane to make the gears connected with the motors be engaged with the inner surfaces of the guiding rails; and each of the motors is connected with a plane power supply bus through power supply lines, and each of the motors is connected with a plane data bus through signal lines. The adjusting device can realize the adjustment of the angle between the symmetrical plane of the empennages and the symmetrical plane of an airplane body, so the pneumatic efficiency of the airplane is effectively increased. The adoption of four motors in the invention improves the reliability of the device.

Description

technical field [0001] The invention relates to the technical field of aviation variant aircraft design, in particular to an aircraft V-shaped tail tilt angle adjusting device. Background technique [0002] The camber angle of the V-shaped tail refers to the axis system of the aircraft body (the apex of the nose is the origin, the axis of symmetry of the aircraft is the x-axis, the z-axis along the plane direction is the z-axis, and the z-axis perpendicular to the x-axis is the y-axis). When the installation angle is zero, the angle between the plane of symmetry and the xy plane of one of the two empennages that make up the V-shaped empennage. The projection of the V-shaped tail on the xz plane acts as the horizontal tail of the aircraft, and the projection on the xy plane acts as the vertical tail of the aircraft. It is a component that integrates aircraft pitch control and aircraft lateral heading control. In the case of a certain empennage area, the camber angle of the e...

Problems solved by technology

Its shortcoming is that the effective horizontal and vertical tail areas are almost unchanged under any task status, resulting in idle V-shaped tail projected area

[0004] In addition, the few devices that can change the inclination angle of the airfoil mostly rely on hinges to complete a small-angle adjustment action, which has the problems of inaccurate adjustment and small adjustment range.
