Abstract

The invention discloses a heat-proof and load-bearing integrated structure of a reversible spacecraft, comprising: a heat-proof layer, an adhesive layer and a load-bearing structure; wherein, the heat-proof layer is connected to the load-bearing structure through the adhesive layer The load-bearing structure is provided with connection holes, and the heat-proof layer is provided with threaded holes corresponding to the connection holes, and screws pass through the connection holes and threaded holes in turn to connect the heat-proof layer and the load-bearing structure; The load-bearing structure is connected to the internal cabin structure and used to connect internal instruments and equipment. The invention has both heat-proof performance and load-bearing performance, and has the function of detachable and reusable.

Description

technical field [0001] The invention belongs to the technical field of thermal protection systems for returnable spacecraft at the second cosmic speed, and in particular relates to an integrated structure of heat protection and load bearing for returnable spacecraft. Background technique [0002] The reentry spacecraft re-enters the flight process at the second spaceflight speed, most of the kinetic energy is converted into heat energy of the air, and these heat energy forms a very high aerodynamic heating environment on the surface of the spacecraft in the form of boundary layer convection and shock wave radiation. The outer surface of the spacecraft There must be a reliable, erosion-resistant thermal protection system to protect the life safety of astronauts and the equipment inside the spacecraft. The structural stability and integrity of the heat-resistant material on the surface have higher requirements. At the same time, the heat-resistant layer is connected with the i...
