A reusable shape memory alloy spacecraft landing buffer

Abstract

A reusable shape memory alloy spacecraft landing buffer, which adopts a porous block shape memory alloy structure bonded by multi-layer wave buffer structure, uses the phase transition process of shape memory alloy material in the deformation process to dissipate energy, Realize the effect of buffering and absorbing energy, and at the same time use the memory effect of the shape memory alloy material on the original shape, and make it return to the original shape by heating, so as to realize the reusable use of the buffer.

Description

Technical field [0001] The present invention relates to a reusable shape memory alloy spacecraft landing buffer belonging to the field of spacecraft landing buffer technology. Background technique [0002] During the spacecraft, the buffer is required to reduce the impact on the internal person and load, while the conventional buffer device typically uses the shaped deformation produced by the buckling of the buckling of aluminum cellular compression, but aluminum honeycomb compression bucks. It is difficult to achieve automatic reset without reuse. Equalizing the benefits and costs, in one flight task needs to carry out multiple people and materials, for this purpose, the spacecraft can be able to make multiple soft landings, and it is difficult to replace or maintain the traditional buffer device in a deep-air environment such as moon. Meet the requirements of flight missions. Inventive content [0003] The technical problem to be solved by the present invention is to overcome...

AI Technical Summary

Problems solved by technology

[0002] During the landing process of a spacecraft, it is necessary to use a buffer device to reduce the impact on the internal personnel and loads, and the traditional buffer device usually uses the plastic deformation caused by the buckling of the aluminum honeycomb compression to buffer energy consumption, but the aluminum honeycomb compression occurs buckling Difficult to achieve automatic reset after that, and cannot be reused

Taking into account both benefits and costs, it is necessary to launch multiple personnel and materials in one flight mission. For this reason, the spacecraft needs to be able to perform multiple soft landings. However, it is difficult to replace or maintain traditional buffer devices in deep space environments such as the moon. Meet the requirements of the flight mission
