Novel nano satellite structure with self-carrying launching function

Abstract

The invention relates to a satellite structure in the field of spaceflight, in particular to a nano satellite structure with a self-carrying launching function. The invention solves the problems that an independent carrying launching system needs to be designed for launch of an existing nano satellite and the utilization rate of the existing nano satellite cannot be improved. The invention adopts the technical scheme of constructing a novel structure which comprises a satellite structural frame, a satellite external mask, a micro-separation part, a satellite platform equipment part and a satellite payload. The satellite platform equipment part and the satellite payload are arranged on the satellite structural frame and the satellite external mask; a nano satellite is connected and fixed to a primary component carried with the nano satellite by the micro-separation part; an L-shaped positioning block and a pin pulling type bolt are respectively arranged on the upper and lower surfaces of a separation surface mask of the primary component carried with the nano satellite for carrying out connection and fixing on the nano satellite; and after the primary component carried with the nano satellite enters a preset orbit, a fixed pin is removed by a pin puller inside the pin pulling type bolt and the nano satellite is released. The nano satellite structure has universality and the carrying launch of the nano satellite can be completed only by installing the micro-separation part on the primary component carried with the nano satellite.

Description

technical field [0001] The invention relates to a satellite structure in the aerospace application field, in particular to a nano-satellite structure with a self-carrying launch function. Background technique [0002] One of the carrying methods of nanosatellites is to carry large satellites to launch, and release them in orbit after entering the predetermined orbit. At present, the nano-satellite structure at home and abroad mainly adopts the following four forms: integral type, box-plate type, shell type, and IKEA type. The advantages of the integral structure are high strength, light weight, and good thermal and electrical conductivity; the disadvantages are difficult processing, high cost, poor design flexibility, and reprocessing when the structural design needs to be modified. The advantage of the box-plate structure is that it is easy to install and disassemble, easy to maintain internal components, and the cross bars can enhance the structural rigidity; the disadvan...
