The invention relates to a multi-layer heat insulation assembly system for improving the heat insulation effect of a spacecraft. The multi-layer heat insulation assembly system comprises a first multi-layer heat insulation assembly and a second multi-layer heat insulation assembly. The first multi-layer heat insulation assembly and the second multi-layer heat insulation assembly wrap the outer surface of a heat-insulated spacecraft structure in sequence, and the first multi-layer heat insulation assembly is attached to the surface of the heat-insulated spacecraft structure. A certain gap is kept between the first multi-layer heat insulation assembly and the second multi-layer heat insulation assembly. The problems that in an existing spacecraft thermal control design, due to contact heat conduction between reflecting screens, heat insulation of the multi-layer heat insulation assemblies is insufficient, and in order to enhance the heat insulation effect of the multi-layer heat insulation assemblies, large structural parts such as a structural sleeve are additionally arranged, and the thermal control design size and weight exceed limits are solved.
本发明涉及一种用于航天器增加隔热效果的多层隔热组件系统,包括第一多层隔热组件、第二多层隔热组件;第一多层隔热组件、第二多层隔热组件先后包覆在被隔热航天器结构的外表面,第一多层隔热组件与被隔热航天器结构表面贴合;第一多层隔热组件、第二多层隔热组件之间保持一定间隙。本发明解决了现有航天器热控设计中因反射屏之间接触导热造成多层隔热组件隔热不充分,以及为加强多层隔热组件隔热效果而增加结构套筒等大型结构件导致热控设计尺寸和重量超限的问题。
