AI Technical Summary

Technical Problem

Spacecraft with existing solar sail push function cannot adjust the light area that the solar sail can receive in time according to the operating trajectory, resulting in low working efficiency and unsatisfactory operation speed. At the same time, long-term sun exposure on the surface of the solar sail leads to electromagnetic radiation, affecting radio wave signal transmission.

Method used

A spacecraft with a solar sail push function including a deployment mechanism and a adjustment device is designed. Through the cooperation of a driving motor, a rotating rod, a moving rod and a adjustment rod, the expansion, recycling and angle adjustment of the solar sail body is realized; at the same time, a self-cleaning component is used to automatically clean the surface of the solar sail using a cleaning brush.

Benefits of technology

By adjusting the angle of the solar sail, the amount of light inflow is increased, the light pressure is increased, the spacecraft's flight speed and working efficiency are improved; the self-cleaning components effectively remove ions generated by solar radiation, improve conversion efficiency, and extend the service life of the equipment.
