The invention discloses a two-dimensional secondary unfolding solar wing which has a folding state, a primary unfolding state, a secondary unfolding state and a two-dimensional secondary unfolding state and comprises a root hinge, a connecting frame, an inner plate, a middle inner plate, a middle outer plate, an outer plate, an upper side plate, a lower side plate, a primary pressing and releasingdevice, a secondary pressing and releasing device and a side plate releasing device. The root hinge, the connecting frame, the inner plate, the middle inner plate, the middle outer plate and the outer plate are hinged in sequence; the root hinge is used for mounting the connecting frame on the side wall of a satellite body; an upper side plate and a lower side plate are hinged to the other two sides of the middle outer plate, and the upper side plate and the lower side plate are oppositely arranged when being unfolded; the primary pressing and releasing device and the secondary pressing and releasing device both have a pressing state and a releasing state. The solar wing can be unfolded step by step before and after orbital transfer of a satellite, the unfolding inertia of the solar wingduring orbital transfer of the satellite is reduced, and the strength requirement of the solar wing is reduced, so that the product quality is greatly reduced.

    本发明公开了一种二维二次展开太阳翼,该太阳翼具有收拢状态、一次展开状态、二次展开状态以及二维二次展开状态,并包括根部铰链、连接架、内板、中内板、中外板、外板、上侧板、下侧板、一次压紧释放装置、二次压紧释放装置以及侧板释放装置;根部铰链、连接架、内板、中内板、中外板以及外板依次铰接,根部铰链用于将连接架安装于卫星的星体侧壁;在中外板的另外两侧铰接有上侧板和下侧板,并且在展开时上侧板和下侧板相对设置;一次压紧释放装置和二次压紧释放装置均具有压紧状态和释放状态。上述太阳翼能够在卫星变轨前后分步进行展开,减小了卫星变轨时太阳翼的展开惯量,降低了太阳翼的强度需求,从而大幅降低产品质量。
