Abstract

A landing supporting mechanism of an asteroid lander comprises an unfolding locking mechanism, a cantilever structure and a landing buffer. The unfolding locking mechanism is connected with the lander. The cantilever structure and the unfolding locking mechanism are connected through a rotating shaft and rotate around the rotating shaft. The landing buffer is fixedly connected with the cantileverstructure. The unfolding locking mechanism provides rotation power for rotation of the cantilever structure through driving force springs; after the unfolding locking mechanism moves to the assigned position, locking is conducted; and when the lander starts to touch the bottom, the landing buffer conducts buffering and speed reduction till the lander finally stably lands. The landing supporting mechanism can be used for meeting a series of specific function requirements of asteroid spacecrafts in the future, and the function realization, weight reduction and miniaturization design of spacecraft products is achieved.

Description

technical field

[0001] The invention belongs to the field of asteroid detection in deep space exploration, and relates to a retractable support and buffer device for asteroid landing detection. Background technique

[0002] At present, the only spacecraft that have achieved asteroid landing and attachment are the European Space Agency's "Rosetta" and Japan's "Hayabusa".

[0003] "Rosetta" deploys three outriggers. When the foot pads just touch the surface of the asteroid, the universal joint connecting the base body of the lander and the landing frame is loosened, so that a small angular momentum is transmitted to the body of the lander. When the three foot pads all touch the star catalog, the gimbal is locked, so that the pose of the lander base body can basically remain unchanged, and it can adapt to the terrain well. There is an electromagnetic damping buffer between the landing frame and the base body of the lander, which can absorb most of the energy during the collisi...
