Small reusable landing buffer mechanism for star catalogue multi-point detection and operation method thereof

Abstract

The invention discloses a small reusable landing buffer mechanism for star catalogue multi-point detection and an operation method thereof, and relates to the technical field of spacecraft structures and mechanisms; all terrain self-adaption systems are arranged on a body frame and vertically slide relative to the body frame, all horizontal energy absorption devices are arranged on one terrain self-adaption system, and each vertical buffering system is arranged on a horizontal energy absorption device and is of a bionic cat leg structure. The terrain self-adaption systems vertically slide along the body frame to adapt to an uneven star catalogue; the horizontal energy absorption devices adopt the friction braking energy absorption principle, the vertical buffering systems can rotate around a main rotating shaft, and impact energy in the horizontal direction during landing is absorbed to a certain extent; the vertical buffering systems adopt a bionic cat leg structure, absorbs impact energy in the vertical direction through joint deformation, and also can participate in absorption of a certain amount of impact energy in the horizontal direction.

Description

technical field [0001] The invention relates to the technical field of spacecraft structures and mechanisms, in particular to a small reusable landing buffer mechanism and an operation method for multi-point detection of star catalogs. Background technique [0002] The landing buffer mechanism of the lunar exploration lander is used to buffer the impact of the spacecraft when it lands. When the lander is performing lunar or planetary landing detection, it first realizes the deceleration through the work of reverse thrust engines and other equipment, but when it completely touches the moon or planet It is difficult to reduce the speed before the surface to zero, which makes the lander need to be subjected to huge impact loads, and is prone to rollover in complex terrain. To ensure the lander finally lands safely, the remaining energy must be absorbed through the landing buffer system. [0003] Up to now, according to the different buffering principles, there are four types of...

Problems solved by technology

[0006] To sum up, the landing buffer systems of most of the current extraterrestrial landers will be in a fixed attitude after deployment, and will choose a relatively flat terrain before landing. The detection range is very limited and cannot be reused.

However, in our country's future lunar exploration missions, it may land on complex terrain such as the edge of the impact crater, mountain slopes, and gravel areas where more deep material is exposed. After the detection of one point is completed, it will take off again to the next detection point , which puts forward higher requirements on the buffer mode, terrain adaptation and reusability of the lander
