Abstract

The invention provides a reusable high-temperature deceleration plate mechanism, which is used for assisting deceleration of high-speed aircraft after landing. Including thin skin structure, skeleton structure, actuator, and scale-type retractable heat shield. The thin skin structure is made of high-temperature-resistant titanium alloy material. The skeleton structure is designed with gradient load-bearing combined ribs. A self-lubricating metal-based composite casing is provided, and a scale-type retractable heat-resistant baffle is installed at the mouth frame of the machine body where the actuator is installed. The invention comprehensively considers the requirements of temperature resistance, strength, rigidity and weight reduction, and takes into account the requirements of repeated use, and can meet the application requirements of high-speed aircraft.

Description

technical field [0001] The invention belongs to the technical field of speed brakes, and in particular relates to a high-temperature speed brake mechanism for repeated use. Background technique [0002] Reusable high-speed aircraft usually use airbrakes to assist the aircraft to decelerate when returning. Unlike conventional subsonic aircraft, high-speed aircraft have to go through a high-temperature process. When the airbrake is working, the body may still be at a relatively high temperature. The moving parts under the coupling state of force and thermal load are also subject to the constraints of the lightweight index of the body, so the design is difficult. Therefore, there is an urgent need for a reusable high-temperature-resistant speedbrake structure. Contents of the invention [0003] The object of the present invention is to provide a reusable high-temperature speed brake mechanism to solve the problem of deceleration of high-speed aircraft during landing after exp...
