Solar sail
专利汇可以提供Solar sail专利检索，专利查询，专利分析的服务。并且PURPOSE: To made it possible that attitude control is performed without requiring propellant powder, etc., in a solar sail that performs attitude control of a space equipment by providing a spring made of shape memory alloy that acts on a blade in the vicinity of a rotary shaft supporting the blade that catches solar wind.
CONSTITUTION: In an artificial satellite wherein solar sails 1-4 are integrated, a supporting bracket 6 that supports the rotary shaft 11 of sollar sails is integrally provided to a mounting bracket 5 to mount solar sails to the structural body of a flight vehicle, and a blade 13 is supported by the rotary shaft 11 through a support 12. A holder 15 that props a heater shaft 14 freely slidable is provided to the supporting bracket freely rotatable, shape memory alloy springs (SMA spring) 9, 10 are mounted on the outside of the heater shaft 14, and heat up heaters 7, 8 are provided to heat these SMA springs, and the sails are changed to the housed state by turning the heat up heaters 8 on to heat the SMA spring 10, and shrink it. On the other hand, the sails are changed to the expanded state when the heaters 7 are turned ON.
