Device for adjusting camber angle of V-shaped empennage

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.
