Abstract

The invention relates to an expandable cubesat for a space material experiment. The expandable cubesat comprises a support frame, a support rod, a differential rotation driving mechanism, an optical imaging mechanism and a plurality of sample tray layers; a sample tray supporting table is connected to the support frame, the sample tray supporting table comprises a plurality of annular steps which are arranged in a stepped mode, the heights of the annular steps are reduced layer by layer from inside to outside, a sample tray layer is arranged on each annular step, each sample tray layer comprises a plurality of sample trays, and one end of each sample tray is hinged to the corresponding annular step; one end of the support rod is connected with the differential rotation driving mechanism, the optical imaging mechanism is installed on the supporting rod, and the sample trays of the sample tray layers are unfolded towards the periphery of the support rod through a locking and releasing mechanism; and the differential rotation driving mechanism is connected with the annular steps of the sample tray supporting table and drives the annular steps to drive the sample trays on the annular steps to rotate around the support rod. The cubesat platform is small in size, simple in structure, low in cost and short in development period.

Description

technical field [0001] The invention relates to the related technical fields of space material experiments and micro-satellites, in particular to a deployable cube star used for space material experiments. Background technique [0002] During the operation of the spacecraft, it may be affected by the space environment, such as extreme temperature, atomic oxygen, high-energy particles and micrometeorites, etc. These space environments may cause the failure of the materials, structures and functional components of the aircraft, which may cause the aircraft to malfunction. Therefore, it is of great significance to understand the performance, stability and long-term behavioral changes of materials in space. Laboratories on Earth can only simulate a limited number of space environments at a time, and the laboratory conditions for ground material exposure experiments are limited. To gain insight into how materials behave in the space environment, various space material experiment...
