Abstract

The invention discloses an inverted reusable landing buffer supporting frame of a triangle spacecraft. The supporting frame comprises foot cushions, main buffer legs, vice buffer legs and unfolding and folding frames. The main buffer legs are respectively connected with an spacecraft body and the vice buffer legs through cardan joints, the main buffer legs and the vice buffer legs are hinged to the foot cushions, the vice buffer legs are connected with the unfolding and folding frames through the cardan joints, and the unfolding and folding frames are in pin joint with the spacecraft body. Bythe combination of the foot cushions, the main buffer legs, the vice buffer legs and the unfolding and folding frames, the inverted reusable landing buffer supporting frame achieves the reuse of a landing spacecraft, satisfies the design requirement of reliable soft landing of the multi-use spacecraft, compensates the defect of poor reusability of a landing device of the traditional spacecraft, and solves the problem of poor universality of the traditional spacecraft.

Description

technical field

[0001] The invention relates to a reusable landing buffer support for an inverted triangle spacecraft, which is especially suitable for the landing buffer process of spacecraft and belongs to the technical field of spacecraft landing structures. Background technique

[0002] In recent years, many concepts of reusable aircraft have been proposed at home and abroad. Due to the characteristics of reusable aircraft that can be reused many times, which can greatly reduce the cost of spacecraft, it has attracted more and more attention from relevant research and development units. For landing spacecraft, such as multi-purpose spacecraft, the landing method is relatively simple and does not have the characteristics of reusability.

[0003] When a multi-purpose spacecraft lands on the surface of various stars, it needs to withstand a large impact force. Especially when the spacecraft is a spacecraft carrying people or precision instruments, it is necessary to adopt a...

Embodiment Construction

[0029] In order to make the solution of the present invention clearer, the present invention will be further described below in conjunction with the accompanying drawings and specific embodiments:

[0030] Such as Figure 1~4 As shown, a reusable landing buffer bracket for an inverted triangle spacecraft, four sets of landing buffer brackets are equipped on a spacecraft body 5, and each set of landing buffer brackets specifically includes a foot pad 1, a main buffer leg 2, and a secondary buffer leg 3 and the retractable frame 4; the main buffer leg 2 is connected to the spacecraft body 5 and the auxiliary buffer leg 3 respectively through universal joints, the main buffer leg 2 and the auxiliary buffer leg 3 are both hinged with the foot pad 1, and the auxiliary buffer leg 3 is connected through the universal joint The joint is connected with the unfolding frame 4, and the unfolding frame 4 is pinned with the spaceship body 5.

[0031] Preferably, the main buffer leg 2 adopt...
