Claims

[Scope of utility model registration request]

Artificial satellite, spacecraft, Orbital Se
In a solar sail that is attached to a position that can generate a moment on the structure of an object flying in space such as a rvice vehicle, there is a rotating shaft that allows the solar sail to freely open and close the blades that receive the solar wind, and a rotating shaft around the rotating shaft. A shape memory alloy spring 1 that acts in a direction to expand the blade, a shape memory alloy spring 2 that acts in a direction to house the blade around the rotation axis, and a radiation heater for heating and deforming the shape memory alloy spring 1. 1, and a radiation heater 2 for heating and deforming the shape memory alloy spring 2.
