Thermal protection structure for variable cross-section non-rotary body and thermal protection forming process

Abstract

The invention belongs to the field of composite material forming, and particularly relates to a thermal protection structure for a variable cross-section non-rotary body and a thermal protection forming process. The thermal protection structure for the variable cross-section non-rotary body comprises a variable cross-section non-rotary metal cabin body. The thermal protection structure is characterized in that an attachment structure is machined on the surface of the metal cabin body, a rubber face is formed on the attachment structure in a coating mode, and a heat shield is laid and solidified on the rubber face. According to the thermal protection structure suitable for the metal cabin of the variable cross-section non-rotary body and the thermal protection forming process, the connection reliability between the heat shield and the metal cabin is guaranteed.

Description

technical field [0001] The invention belongs to the field of composite material forming, and in particular relates to a thermal protection structure of a non-revolving body with variable cross-section and a forming process. Background technique [0002] With the rapid development of the aerospace industry, the development of aircraft thermal protection systems has become a hot topic. At present, resin-based ablative heat-resistant materials have been widely used in high-tech fields such as various aircrafts due to their many advantages. [0003] The shell of a common aircraft is a metal gyratory. Generally, heat protection materials are laid directly on the surface of the metal shell. When the parts of the gyratory are used, the laid heat protection layer will form a complete gyratory. The overall structural strength of the layer is good, it can withstand a certain impact, and can ensure the reliability of the connection between it and the shell, but there are also some spe...

[0003] The shell of a common aircraft is a metal gyratory. Generally, heat protection materials are laid directly on the surface of the metal shell. When the parts of the gyratory are used, the laid heat protection layer will form a complete gyratory. The overall structural strength of the layer is good, can withstand a certain impact, and can ensure the reliability of the connection between it and the shell, but there are also some special cases. With some design requirements, the shell of some aircraft is a kind of The non-revolving body with variable cross-section, and the shell is made of metal materials. When the heat protection layer is processed on the surface of this kind of non-rotating shell
