PROBLEM TO BE SOLVED: To provide a solar sail capable of efficiently performing orbit control while not changing the attitude of a spacecraft body.SOLUTION: A solar sail includes: small sails 11 divided in triangular sail blocks R having one apexes at a spacecraft body, each sail block being formed in a rectangular plate shape with a one side face forming a reflection surface; connection bodies 12 engaging with four corners of the small sails, juxtaposing and holding the plural small sails at predetermined intervals; an actuator 14 connected with one ends of the connection bodies and changing the angles of the reflection surfaces of the small sails by adjusting the lengths of the connection bodies; and weights 13 provided at the other ends of the connection bodies and spreading the solar sail formed of the plural sail blocks by centrifugal force generated when the spacecraft body spins.SELECTED DRAWING: Figure 1
【課題】宇宙機本体の姿勢を変えない状態で軌道制御を効率的にできるソーラセイルを提供する。【解決手段】ソーラセイルが、宇宙機本体を1つの頂点とする3角形のセイルブロックRに分割され、かつ、各セイルブロックが、矩形板状に形成されて、一方の面が反射面をなす小セイル11と、小セイルの4コーナと係合して、複数の小セイルを所定間隔で並設・保持する連結体12と、連結体の一端が連結されて、当該連結体の長さを調節することで、小セイルの反射面の角度を変えるアクチュエータ14と、連結体の他端に設けられて、宇宙機本体がスピンした際に生じる遠心力で、複数のセイルブロックからなるソーラセイルを展開させる錘13と、を含む。【選択図】図1
