The invention discloses a multi-layer heat insulation assembly heat screen of a camera for a satellite and an installation method of the multi-layer heat insulation assembly heat screen. The multi-layer heat insulation assembly heat screen is composed of two layers of aramid fiber wire frames and a multi-layer heat insulation assembly, a net-shaped structure formed by the aramid fiber wire frames on the two sides plays a role in supporting the multi-layer heat insulation assembly clamped in the middle, and the multi-layer heat insulation assembly heat screen is fixed to a structural plate of a load cabin bottom plate through aramid fiber wires and a nylon base. During installation, the 10-unit multi-layer heat insulation assembly is firstly manufactured; a lower layer aramid fiber line binding point position is selected on the structural plate, a lower layer aramid fiber line frame is arranged, and after the transverse tensioning force of the aramid fiber lines meets the requirement, adhesive dispensing is carried out at the binding position for anti-loose fixing; laying a plurality of layers of heat insulation assemblies, and sewing the lower layer aramid fiber threads and the plurality of layers of heat insulation assemblies together; an upper-layer aramid wire binding point position is selected on the structural plate, an upper-layer aramid wire frame is arranged, and after the transverse tensioning force of the aramid wires meets the requirement, adhesive dispensing is conducted on the binding position for looseness prevention and fixation; and finally, sewing the upper-layer aramid fiber threads and the multi-layer heat insulation assembly together.
本发明公开了一种卫星用相机多层隔热组件隔热屏及其安装方法。多层隔热组件隔热屏由两层芳纶线框架和多层隔热组件组成,两侧芳纶线框架组成的网状结构对夹在中间的多层隔热组件起支撑作用,利用芳纶线及尼龙底座将多层隔热组件隔热屏固定在载荷舱底板的结构板上。安装时,先制作10单元多层隔热组件;在结构板上选择下层芳纶线绑扎点位置,布置下层芳纶线框架,并在芳纶线横向拉紧力符合要求后,在绑扎处点胶防松固定;敷设多层隔热组件,将下层芳纶线与多层隔热组件缝制在一起;在结构板上选择上层芳纶线绑扎点位置,布置上层芳纶线框架,并在芳纶线横向拉紧力符合要求后,在绑扎处点胶防松固定;最后将上层芳纶线与多层隔热组件缝制在一起。
