The invention provides a point type connection and separation moonlet platform structure carrying a large amount of propellants, which relates to the technical field of spacecraft structures, and comprises a frame, a bottom plate, a lower cabin partition plate, a storage box support rod, a middle plate, an upper cabin partition plate, a top plate and side plates, and the side plates surround the bottom plate, the middle plate and the top plate which are arranged in parallel to form a closed box body; the bottom of the bottom plate is connected to the frame, the storage boxes are diagonally arranged in round holes in the bottom plate and the middle-layer plate, and the storage box supporting rods are evenly distributed on the peripheries of the round holes; the box body is divided into an upper cabin and a lower cabin by the middle-layer plate, the upper cabin partition plate is connected into the upper cabin, and the lower cabin partition plate is connected into the lower cabin. The invention provides a structure of point type connection and storage tank sinking, the requirement that a small satellite platform carries a large amount of propellants is met, the mass center of the whole satellite is effectively reduced, and the satellite dynamics environment is improved; and meanwhile, the bottom main force bearing frame is matched with the detachable adapter block to adapt to mechanical interfaces of different carrier rockets, and point type connection and separation are achieved.

    本发明提供了一种涉及航天器结构技术领域的携带大量推进剂、点式连接分离的小卫星平台结构,包括框架、底板、下舱隔板、贮箱撑杆、中层板、上舱隔板、顶板以及侧板,所以侧板将平行排列的底板、中层板以及顶板围绕成一个封闭箱体,底板底部连接于框架上,贮箱对角布置于底板和中层板上的圆孔中,贮箱撑杆均匀分布于圆孔周边;中层板将箱体隔离成上舱和下舱,上舱隔板连接于上舱中,下舱隔板连接于下舱中。本发明提出了“点式连接+贮箱下沉”的构型,满足小卫星平台携带大量推进剂的需求,有效降低整星质心,改善卫星动力学环境;同时底部主承力框架配合可拆卸转接块,可适应不同运载火箭机械接口,实现点式连接分离。
