A connection and separation device for batch launch of satellite groups

Abstract

The invention discloses a connection and separation device for batch launch of a satellite group, which comprises a base, a docking mechanism and a locking mechanism; the docking mechanism is connected to the satellite body, and a plurality of docking mechanisms are overlapped, and the bottommost one is between two adjacent docking mechanisms There is an elastic mechanism between the docking mechanism and the base, the two adjacent docking mechanisms are abutted by the elastic mechanism, and the bottommost one is abutted by the elastic mechanism and the base; the base is connected with the docking mechanism by a locking mechanism, and the locking mechanism is used To fix the docking mechanism on the base. Adopting the scheme provided by the present invention can realize the launch of a large number of satellites at the same time, greatly reduce the launch cost, and provide guarantee for the mass launch of satellites and constellation construction; the design meets the scalability of launching multiple satellites with one arrow and the unity of satellite design and manufacture , the assembly of each satellite before launch is convenient, the requirements are loose, the safety requirements are met during the launch process, and the unlocking in orbit is safe and convenient.

Description

technical field [0001] The invention belongs to the field of aerospace technology, and in particular relates to a connection and separation device for batch launching of satellite groups. Background technique [0002] The connection and unlocking structure between the satellite and the rocket is an important part of the satellite. On the one hand, it provides fixed support for the satellite launch, and on the other hand, it provides the unlocking power when the satellite and the rocket are separated. At present, satellite launches are mainly based on single-satellite launches. In multi-satellite launches, each satellite and the distributor have independent interfaces. The connection and separation methods are simple, widely used, and the technology is mature. With the rapid development of satellites and constellations, the demand for the number of satellites is increasing day by day, especially the rapid development of the global mobile Internet, which makes the demand for t...

AI Technical Summary

Problems solved by technology

[0003] (1) In the rocket envelope, additional distributors need to be designed for multi-satellite launches, and the utilization rate of satellite launch space is low;

[0004] (2) Each satellite needs to design a separate connection and separation structure and pyrotechnics, the structure is complex, which is not conducive to mass production;

[0005] (3) The separation process is complicated, which is not conducive to the constellation deployment and control of satellites in orbit
