Astronavigation stand-alone locking and releasing mechanism

Abstract

An astronavigation stand-alone locking and releasing mechanism comprises a mounting frame and a plurality of compression bars. The mounting frame is arranged at the bottom in a spacecraft cabin. An astronavigation stand-alone is disposed in the mounting frame. Two ends of each compression bar are connected with the mounting frame through explosive bolts respectively. The astronavigation stand-alone is locked in the mounting frame. The astronavigation stand-alone locking and releasing mechanism can tightly lock the astronavigation stand-alone when the spacecraft is launched, and easily unlock the astronavigation stand-alone during in-orbit maintenance of the astronavigation stand-alone.

Description

technical field [0001] The invention relates to a locking and releasing mechanism for an aerospace stand-alone aircraft, in particular to a locking and releasing mechanism for an aerospace stand-alone aircraft that can securely lock a single aerospace aircraft when a spacecraft is launched, and can release the lock when the spacecraft is maintained on orbit. Background technique [0002] With the development of on-orbit maintenance technology, the space maintenance and replacement of aerospace stand-alone products has gradually entered the field of vision of major aerospace companies. Spacecraft on-orbit maintenance technology has been rising since the 1960s. According to the type of service body, it can be divided into two parts: manned on-orbit service and autonomous on-orbit service. Its research can basically be divided into the stage of manned on-orbit maintenance and the stage of autonomous on-orbit service. . On-orbit service uses astronauts to maintain the spacecraf...

Problems solved by technology

[0003] During the launch process of the spacecraft, the single spaceship needs to bear harsh mechanical loads and must be firmly locked. After the spacecraft is launched into orbit, it is in a weightless environment. The force provided by the manipulator is very small, and the existing space manipulator is not flexible and delicate enough. It cannot complete very complicated actions. In order to facilitate the autonomous on-orbit maintenance of the aerospace stand-alone, the locking mechanism of the aerospace stand-alone must be able to firmly lock the aerospace stand-alone during the launch process and be easily unlocked during the on-orbit maintenance.
