Embodiment Construction

[0019] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.

[0020] The present invention proposes a compression and release device suitable for flexible spacecraft, which is used for the compression and release of the separation structure plate 1 and the flexible spacecraft storage box 3; for the separation of the structure plate 1 and the flexible spacecraft storage box 3 Compression and release; the compression and release device includes a compression mechanism 20 and the spring ejector mechanism 10 installed on both sides of the compression mechanism 20; the compression mechanism 20 includes lock nuts 2, electric explosion bolts 8 and bolt collection Box 9. The lock nut 2 is fixed on the separation structure plate 1; in the present invention, two lock nuts are superimposed on each other to realize mutual pre-tightening and anti-loosening; the electric explosion bolt 8 in the compression mechanism 20 passes...

Abstract

The invention discloses a pressing and releasing device suitable for a flexible spacecraft. By means of fastening connection of an electric explosion bolt and matching between a spring and a T-shapedejector rod in a spring ejector rod mechanism, the functions of containing, pressing and synchronous unlocking and releasing of the flexible spacecraft are achieved, and the separation posture of theflexible spacecraft is stable; meanwhile, different satellite-rocket relative separation speeds can be obtained by changing spring parameters, and the device has the advantages of being simple in structure, small in power supply requirement and high in reliability.

Description

technical field [0001] The invention belongs to the field of structural design of flexible spacecraft, in particular to a pressing and releasing device suitable for flexible spacecraft. Background technique [0002] Flexible spacecraft is a new type of spacecraft with the theme of flexible thin-film structures. It has broad application prospects in space missions such as space debris deorbiting, space attack and defense, and space exploration. The storage, compression and smooth release of the flexible spacecraft are the prerequisites to ensure the normal operation of the flexible spacecraft. There is no pressing and releasing device suitable for flexible spacecraft at present. Contents of the invention [0003] In view of this, the object of the present invention is to provide a pressing and releasing device suitable for flexible spacecraft. It can realize the storage and compression of flexible spacecraft and the synchronous unlocking and releasing functions in orbit. ...
