The invention discloses a multifunctional deorbit sail with a large folding and unfolding ratio and a spacecraft, and the multifunctional deorbit sail with the large folding and unfolding ratio comprises a deorbit sail film, a rotation driving device and a folding and unfolding driving device; the surface of the deorbit sail film is of a square structure, a square fixing area is arranged in the center of the deorbit sail film, the four edges of the fixing area extend outwards to form L-shaped folding areas respectively, and swastika-shaped folds are formed on the periphery of the fixing area through the four L-shaped folding areas. The rotary driving device is used for driving the deorbit sail film to rotate; the folding and unfolding driving device is used for driving the four vertexes of the deorbit sail film to synchronously move in the direction close to or away from the fixed area. According to the multifunctional deorbit sail with the large folding-unfolding ratio, the folding-unfolding ratio can be effectively increased, the structure is simple and efficient, and on-orbit multiple-time controllable folding and unfolding of the deorbit sail film can be achieved.
本发明公开一种大折展比的多功能离轨帆及航天器,其中,所述大折展比的多功能离轨帆包括离轨帆薄膜、旋转驱动装置和折展驱动装置;离轨帆薄膜的表面设为正方形结构,离轨帆薄膜的中心位置设有正方形的固定区,固定区的四条边分别向外延伸形成“L”型折叠区,并通过四个“L”型折叠区在固定区的外周构成“卍”型折痕;旋转驱动装置用于驱动离轨帆薄膜旋转;折展驱动装置用于带动离轨帆薄膜的四个顶点同步沿靠近或远离固定区的方向移动。本发明提供的大折展比的多功能离轨帆能够有效提高折展比,结构简单高效,可实现离轨帆薄膜的在轨多次可控折展。
