Aircraft buffer device

Abstract

The embodiment of the present invention discloses a spacecraft buffer device, the buffer device includes several buffer structures arranged in an array along three dimensions of space; the buffer structure includes: a square three-dimensional structure composed of side frames body; and an inner support truss extending from the center of the structure at each corner of the structure; the inner end of each inner support truss is aggregated and fixed at the center of the structure. The cushioning device provided by the present invention utilizes the process of absorbing energy due to deformation of the cushioning structure from the intact state to the damaged state, and arranges it in an array along the three dimensions of the space on the landing surface of the spacecraft to absorb the energy generated when the spacecraft lands. The impact force slows down the impact received by the spacecraft when it lands, which can ensure that the spacecraft can achieve cushioning and energy absorption under different landing angles.

Description

technical field [0001] The invention relates to the field of aerospace technology. More specifically, it relates to a spacecraft cushioning device. Background technique [0002] When a spacecraft re-entries and returns to land on the surface of the earth or a planet, it is necessary to slow down the impact of landing and protect the safety of the payload equipment in the spacecraft, which is of great significance for deep space exploration and the return of in-orbit materials. [0003] Usually, spacecraft use inflatable airbags, landing legs, recoil rockets and other landing buffer systems or means, such as the US Mars probe, China's lunar probe and a new generation of manned spacecraft. The above-mentioned landing buffer system adopts an independent buffer device, including inflation / deflation device, pyrotechnic actuation system, one-way movement rod system, airbag folding storage and deployment, etc. The system has many components and the coupling of the buffering proces...

AI Technical Summary

Problems solved by technology

The above-mentioned landing buffer system adopts an independent buffer device, including inflation / deflation device, pyrotechnic actuation system, one-way movement rod system, airbag folding storage and deployment, etc. The system has many components and the coupling of the buffering process is high. , the ground verification process is complicated

In addition, the existing landing buffer system has a relatively single function, that is, it only plays a role during the landing process of the spacecraft.
