A heat-proof layer forming tool for the outsole of a returnable spaceship

Abstract

A heat-proof layer molding tool for the outsole of a returnable spaceship, including a lower mold (6), a middle mold (4), an upper mold (1), an observation window (2), a vacuum pipeline (3), and a glue injection pipeline (7) , pallet (10), lifting ring (9), compression plate (8), compression frame (12); along the height direction, the tooling is divided into three layers, upper mold (1), middle mold (4), lower mold (6); the middle mold (4), the lower mold (6) are used to hold the spaceship outsole heat-proof layer (11); the mounting surface between the middle mold (4) and the lower mold (6) is in the inner tray (10) ) in the middle of the height direction; the upper mold (1) is used as an upper cover, and after assembly, forms a closed cavity together with the middle mold (4) and the lower mold (6). The invention overcomes the difficult problem that the heat-proof large bottom layer of the returnable airship cannot directly implement the processes of vacuum impregnation, drying and curing.

Description

technical field [0001] The invention relates to a molding tool, which belongs to the field of molding of fiber-reinforced low-density thermal protection materials. Background technique [0002] Due to the need to experience high heat flow erosion during the reentry flight, the outer surface of the returnable spacecraft must have a reliable, erosion-resistant thermal protection system to protect the equipment and personnel inside the spacecraft. With the continuous development of deep space exploration projects, the return of the spacecraft at the second space flight speed to the reentry heat flow environment puts forward the structural strength, structural stability, large-scale integral molding, lightweight structure, and molding quality control of the surface ablation layer of the thermal protection system. Due to higher requirements, the thermal protection materials of traditional returnable spacecraft cannot meet their needs. [0003] Large-size curved long-fiber needle...
