The invention provides a conformal structure suitable for a large-wingspan flexible wing and a design method, and relates to the technical field of aircraft mechanical structure design. The unmanned aerial vehicle is provided with a fuselage and inflatable wings; fuselage fixing pieces are installed on the surface of the fuselage, at least one pulling point is arranged on the surface of each inflatable wing in the wingspan direction of the surface of the inflatable wing, at least one pulling point is located at the wingtip of the inflatable wing, wing fixing pieces are installed at the pulling points, and the wing fixing pieces are connected with the fuselage fixing pieces through traction pieces. According to the large-wingspan flexible inflatable wing, the wing can be prevented from generating large structural deformation in the lift force direction under the gravity and pneumatic action, and the engineering application problem that an existing large-wingspan flexible inflatable wing is large in deformation under the gravity and pneumatic load can be solved; the pulling point arrangement along the spanwise direction and the chordwise direction can be flexibly determined according to flight conditions; a certain dihedral angle or dihedral angle is pre-set for the inflatable wing by adjusting the length of the pull rope, so that the transverse stability of the aircraft is improved.
本发明提供一种适用于大翼展柔性机翼的保形结构及设计方法,涉及飞行器机械结构设计技术领域;包括:具有机身和充气机翼的无人机;所述机身的表面安装有机身固定件,所述充气机翼的表面延其翼展方向至少设置一处拉点,且至少有一处所述拉点位于所述充气机翼的翼梢,所述拉点处均安装有机翼固定件,所述机翼固定件均通过牵拉件与所述机身固定件连接。本发明可以防止机翼在重力和气动作用下在升力方向出现较大结构变形,能够解决现有大翼展柔性充气机翼在重力和气动载荷下变形大的工程应用问题;沿展向和沿弦向的拉点布置可以根据飞行工况灵活确定;通过调节拉绳的长度给充气机翼预支一定的上反角或者下反角,提高飞行器的横向稳定性。
