Abstract

The invention relates to a foldable and unfoldable space platform which comprises a rotary table and a plurality of supporting frames, the supporting frames are each of a foldable and unfoldable structure and annularly arranged on the peripheral side of the rotary table, and every two adjacent supporting frames are hinged to each other; one ends of the multiple supporting frames are connected to the peripheral side of the rotary table through memory alloy, and the supporting frames are made to rotate to preset positions relative to the rotary table through power-on and power-off of the memoryalloy. The exposed area of the space platform is obviously increased after the space platform is unfolded, the occupied area of the whole panel is relatively small in the recycling process, and the launching and recycling cost can be reduced; deformation driving force generated by on-off of the memory alloy is adopted to enable the supporting frame blades to rotate, and then all the supporting frame blades are driven to rotate relative to the rotary table, so that the structural weight can be reduced, the space is saved, and the system reliability is improved.

Description

technical field

[0001] The invention relates to the technical field related to space loads, in particular to a foldable and unfoldable space platform applied to space exposure and planetary scientific sampling return experimental loads. Background technique

[0002] Space exposure experiments can simulate extraterrestrial environments such as the moon and asteroids, provide basis and guidance for scientific experiment tasks in aerospace engineering such as lunar exploration projects, Mars exploration, and asteroid exploration, and can provide abundant scientific research samples. Addition to science experiment quests. Space exposure experiments can simulate the chemical and physical reactions of atmosphere, minerals, biological and other resources in the extraterrestrial environment, help to better understand the extraterrestrial planetary environment, and provide reference information for subsequent deep space exploration, sampling and return missions. The space exposure e...
