Spatial flexible unfolding structure anti-mechanical enhancement accessory

Abstract

The embodiment of the invention discloses a space flexible unfolding structure anti-mechanical enhancement accessory. The accessory comprises a buffer layer, a surface coating layer and an outer adhesion layer, the surface coating layer is coated on the outer surface of the buffer layer; and the outer adhesion layer is adhered to the surface of the contact end of the surface coating layer and the inner wall of the release device or the multi-layer heat insulation assembly. According to the invention, the interference of a traditional buffer filler mode on the internal thermal boundary of the release device is effectively avoided, the thermal design difficulty is reduced, and more weight resources are saved compared with the mode of filling the periphery with buffers; the buffer layer material is prevented from being in contact with the flexible unfolding structure, so that side effects which influence release and unfolding of the flexible unfolding structure, such as generation of redundant substances, precipitation of pollutants and surface adhesion, are effectively avoided; a wedge-shaped mechanism and a surface coating layer lubrication guide rail type design are adopted, so that the kinetic friction force in the release process is effectively reduced, and interference in the release process is avoided; and the method can be realized by adopting common mature materials for spaceflight, so that the economic costs of research, development, purchase and the like are effectively saved.

Description

technical field [0001] The present application relates to the technical field of flexible structure development, and more specifically, the present application relates to a space flexible deployment structure anti-mechanical reinforcement attachment. Background technique [0002] Flexible materials and their unfolded structures are widely used in space. The originator of communication satellites - American Echo 1 and Echo 2 satellites are flexible thin-film balloon satellites. The practice 2B and Atmosphere 1 launched by my country are also used for scientific experiments. In recent years, with the development of aerospace technology, the application of flexible deployment structures has been expanded to include space return and landing, space solar wing deployment, space vehicle de-orbiting, space debris detection and other technical levels. [0003] Limited by the size and space of the carrying platform, the space flexible deployment structure generally needs to be folded a...
