Problems solved by technology

[0002] At present, various countries are developing new take-off and landing methods, and deceleration is one of the important topics. When the aircraft lands, in order to accelerate the deceleration effect, baffles will be added on the wings. When landing, open the baffles to increase wind resistance. Improve the deceleration effect, but the current baffle opening structure is complicated and the production cost is high

Abstract

The invention provides a wing aerodynamic speed reducing mechanism, which includes a wing, an airbrake and a controller. The airbrake is disposed inside the wing, an opening is disposed at a position corresponding to that of the airbrake upper surface on the wing upper surface, the opening is provided with a movable plate, and the lower part of the movable plate is in fixed connection with the airbrake upper surface. First fixation blocks and second fixation blocks are respectively arranged at corresponding positions on two sides at the lower part of the airbrake, and are hinged to first pull rods and second pull rods respectively, the other ends of the first pull rods and second pull rods are hinged to first sliding blocks and second sliding blocks respectively, the first sliding blocks and the second sliding blocks are in threaded connection with first screw rods and second screw rods respectively, and the first screw rods and the second screw rods are connected to the output shafts of first screw rod motors and the output shafts of second screw rod motors. The wing aerodynamic speed reducing mechanism provided by the invention has the characteristics of simple structure and stable operation, and can quickly open the airbrake to meet operating requirements.

Description

technical field [0001] The invention belongs to the technical field of aircraft, and in particular relates to a wing aerodynamic deceleration mechanism. Background technique [0002] At present, various countries are developing new take-off and landing methods, and deceleration is one of the important topics. When the aircraft lands, in order to accelerate the deceleration effect, baffles will be added on the wings. When landing, open the baffles to increase wind resistance. Improve the deceleration effect, but the current baffle opening structure is complicated, and the production cost is high. Contents of the invention [0003] The object of the present invention is to solve the above-mentioned problems in the prior art, and provide a wing aerodynamic deceleration mechanism with simple structure, stable operation, and the ability to quickly open the deceleration brake. [0004] The technical solution adopted by the present invention to solve its technical problems is: ...
