The invention discloses a multi-purpose tooling for a heat-proof and load-bearing integrated structure of a reversible spaceship, which includes: a threaded hole sleeve, a threaded hole plug block and a threaded hole sleeve positioning pin; wherein, the heat-resistant and load-bearing integrated structure has Threaded hole, the threaded hole sleeve is set in the threaded hole; the threaded hole sleeve plug block can be embedded in the threaded hole sleeve, and is used for positioning the embedded parts in the integrated structure of heat protection and load bearing; the threaded hole sleeve is positioned The pin can be embedded in the threaded hole sleeve, which is used to position the gasket at the corresponding position of the embedded part in the heat-proof and load-bearing integrated structure of the reversible spacecraft and to tighten and pressurize the gasket when it is glued and solidified. The invention effectively protects the heat-resistant material of the outer heat-resistant layer, and at the same time realizes the positioning of the embedded parts of the inner-layer load-bearing structure, the positioning of the gaskets at the corresponding positions, and fastening and pressing when the gaskets are glued and solidified, and can be disassembled repeatedly. It is suitable for a variety of embedded parts, and the design of embedded parts with different positioning requirements can be adjusted in a targeted manner to make the products more diverse.
Description
technical field [0001] The invention belongs to the technical field of thermal protection systems for reversible spacecraft at the second cosmic speed, and in particular relates to a multipurpose tooling for the integrated structure of heat protection and load bearing of reversible 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 la...
