PROBLEM TO BE SOLVED: To provide a spacecraft and an orbital plane change method therefor capable of changing the orbital plane of a rotating orbit around the earth to another orbital plane different in the orbital inclination or in the right ascension of the ascending node immediately at the time of need and in a short period of time with significantly less fuel than ever before.SOLUTION: A spacecraft 10 comprises: wings or an airframe which generates lift in an atmosphere; a thruster which accelerates or decelerates rotating speed in an orbit; an attitude controller which controls an attitude of the airframe; and an orbital plane controller which controls the orbital plane change. The orbital plane controller causes the spacecraft 10 to enter the earth's atmosphere 2 within a pre-change orbital plane (A→B→C), changes the orbital plane by using the lift of the wings or airframe in the earth's atmosphere 2 (C→D→E), and then lifts the spacecraft 10 up to the post-change orbital altitude (E→F).SELECTED DRAWING: Figure 6
【課題】従来よりも大幅に少ない燃料で、必要時に即時かつ短期間に、地球の旋回軌道上から軌道傾斜角や昇交点赤経の異なる別の軌道面に変更することができる宇宙機とその軌道面変更方法を提供する。【解決手段】宇宙機10は、大気中で揚力を発生する翼又は機体と、軌道上の旋回速度を加速又は減速するスラスタと、機体を姿勢制御する姿勢制御装置と、軌道面変更を制御する軌道面制御装置と、を備える。軌道面制御装置は、変更前の軌道面内で、宇宙機10を地球大気2内に突入させ(A→B→C)、地球大気2内で、翼又は機体の揚力を利用して軌道面を変更し(C→D→E)、次いで、変更後の軌道高度まで宇宙機10を上昇させる(E→F)。【選択図】図6
