The invention discloses an aerodynamic layout of a large-lifting-surface ultra-low orbit aircraft. The aerodynamic layout comprises an aircraft body, a group of pneumatic sails and a group of solar cell wings. The aircraft body provides an equipment installation space, the cross section of the aircraft body is of an equilateral triangle structure, the side length is W, the length is L, the large-lifting-surface pneumatic sail is located under the aircraft body and provides main mechanical loads and the solar cell piece distribution area, and the solar cell wings are attached to the upper surface of the pneumatic sail. According to the designed large-lifting-surface aerodynamic layout, the lift-drag ratio of the aircraft can be effectively increased under the condition that the design requirement for the fixed included angle of the antenna is met, the orbit plane where the aircraft runs is changed in a pneumatic assisting mode, and therefore the aircraft can achieve large-range orbit inclination maneuvering on an ultra-low orbit with the minimum fuel consumption.
本发明公开了一种大升力面超低轨飞行器气动布局,包括飞行器本体、一组气动帆和一组太阳电池翼。所述飞行器外形的本体提供设备安装空间,其横截面为等边三角形结构,边长为W,长度为L,大升力面气动帆位于飞行器本体的正下方,提供主要的力学载荷和太阳电池片布片面积,太阳电池翼贴于气动帆上表面。本发明所设计的大升力面气动布局在满足天线固定夹角的设计要求下可有效增加飞行器的升阻比,通过气动辅助方式改变飞行器运行的轨道平面,从而以最小的燃料消耗让飞行器在超低轨道实现大范围的轨道倾角机动。
