Connecting and separating device for satellite batch launching

Abstract

The invention discloses a connecting and separating device for satellite batch launching. The connecting and separating device comprises a base, docking mechanisms and a locking mechanism. The dockingmechanisms are connected with the satellite body, the multiple docking mechanisms are arranged in an overlapped mode, elastic mechanisms are arranged between two adjacent docking mechanisms and between the bottommost docking mechanism and the base, the two adjacent docking mechanisms are connected in an abutting mode through the corresponding elastic mechanism, and the bottommost docking mechanism is connected with the base in an abutting mode through the corresponding elastic mechanism. The base is connected with the docking mechanism through the locking mechanism, and the locking mechanismis used for fixing the docking mechanism to the base. By adopting the scheme provided by the invention, large-batch satellite launching can be simultaneously realized, the launching cost is greatly reduced, and guarantee is provided for satellite large-batch launching and constellation construction; the design meets the expandability of one-rocket multi-satellite launching and the uniformity of satellite design and manufacturing, all satellites are convenient to assemble and loose in requirement before launching, the safety requirement is met in the launching process, and on-orbit unlocking issafe 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
