Abstract

The invention discloses a satellite flexible repeatable folding and unfolding defense device for resisting physical impact, and particularly relates to the technical field of ultra-high-speed impact spacecraft protection. The satellite flexible repeatable folding and unfolding defense device capable of resisting physical impact comprises a motor, a repeatable folding and unfolding mechanism and abutt joint locking mechanism, the repeatable folding and unfolding mechanism comprises a root joint hinge, a middle joint hinge and a top joint hinge, the root joint hinge is used for driving the middle joint hinge to rotate, and the middle joint hinge is used for driving the top joint hinge to rotate; the top joint hinge is used for driving the butt joint locking mechanism to rotate, the flexibleprotection layer is provided with multiple stages of buffers, the butt joint locking mechanism comprises a telescopic sleeve, a suction piece and an electromagnetic lock body, the telescopic sleeve is arranged on the top joint hinge, and butt joint plates are arranged on the suction piece and the electromagnetic lock body. By the adoption of the technical scheme, the problems that an existing space debris protection structure is poor in protection effect and limited in protection performance are solved, and the service life of a satellite can be prolonged.

Description

technical field [0001] The invention relates to the technical field of ultra-high-speed impact spacecraft protection, in particular to a satellite flexible and repeatable folding defense device against physical impact. Background technique [0002] The space environment is deteriorating day by day, and the number of space debris is increasing at an accelerated rate. The major aerospace countries are vigorously developing kinetic energy anti-satellite weapons, which seriously threatens the safety of spacecraft in orbit. The existing space debris protection technology adopts passive defense structures, and is basically used for large Spacecraft can only defend against millimeter-scale space debris attacks, the protection effect is not good, and the protection performance is limited. It is necessary to design an active space debris protection load to replace the traditional fixed external passive protection structure, improve the survivability of the satellite, and prolong the ...
