Follow-up device of horizontal tail of airplane

Abstract

The invention belongs to the technical field of airplane structure design, and particularly relates to a follow-up device of a horizontal tail of an airplane. The device is characterized by comprising a sealing plate, a roller trigger device, a torque arm support, a stop block, a torque arm, a hinge, a hinge support, a torque rod, a torque rod mounting support, a hinge support and a hinge, wherein the roller trigger device is mounted on the sealing plate, the two hinges are mounted on the sealing plate coaxially, the hinges are connected with the hinge supports, and the hinge supports are connected with an external machine body. The torque rod mounting support is connected with the hinge support by a bolt; the torque rod is connected with the torque rod mounting support and the torque arm; the torque rod penetrates through a through hole of the hinge support and can rotate freely in the hole; a double-lug of the torque arm is connected with a single lug of the torque arm support; the torque arm support is connected with the sealing plate; and the sealing plate is limited on the external machine body. The device has the advantages that the device is light in weight and convenient to mount, and occupies a small space; the whole follow-up device is basically in a plane of the sealing plate and is simpler in structure; and the mounting is not influenced by external members.

Description

Technical field [0001] The invention belongs to the technical field of aircraft structure design, and specifically relates to an aircraft flat tail following device. Background technique [0002] At the movable parts of the aircraft, follow-up devices need to be arranged to realize the different functions of the aircraft. The horizontal stabilizer of a large aircraft generally needs to be adjusted and trimmed during flight, and an opening for the horizontal tail movement needs to be provided at the installation of the horizontal tail. The opening is too large, which brings problems to the aerodynamic sealing of the aircraft. By arranging a follower device, it not only satisfies the movement opening requirement of the flat tail, but also satisfies the sealing requirement. However, the current follow-up devices generally realize follow-up through rocker arms, pull rods, hydraulic devices, etc., which have complex structures, many movements, and take up a large space. When the spac...
