The invention discloses a bionic folding unmanned aerial vehicle using flexible airfoils and a using method thereof, which belong to the technical field of miniature unmanned aerial vehicles. The specific structure of the unmanned aerial vehicle comprises a micro power system, a wing leading edge, a main fuselage, a servo mechanism, a foldable control surface control mechanism, a V-shaped empennage and a flexible wing surface. The micro power system is fixed at the front end of the main fuselage; the left side and the right side of the front end of the main fuselage are each provided with a foldable wing leading edge, and the left side and the right side of the rear end of the main fuselage are each provided with a foldable control surface control mechanism controlled by a servo mechanism. And the foldable V-shaped empennage is arranged at the tail end of the main fuselage. After the unmanned aerial vehicle pops up, the wing leading edge, the unmanned aerial vehicle foldable control surface control mechanism and the V-shaped empennage are automatically opened under the elastic effect, so that the flexible wing surface is unfolded. The flexible airfoil design is adopted, so that the folding unmanned aerial vehicle can obtain a larger wing area and higher aerodynamic efficiency, the lift coefficient is improved, the minimum level flight speed of the unmanned aerial vehicle is reduced, and the folding unmanned aerial vehicle has better maneuverability.
本发明公开了一种使用柔性翼面的仿生折叠无人机及其使用方法,属于微型无人机技术领域。无人机具体结构包括微型动力系统、机翼前缘、主机身、伺服机构、可折叠舵面控制机构、V型尾翼、柔性翼面;主机身前端固定微型动力系统;主机身前端左右两侧各设置有一个可折叠机翼前缘,后端左右两侧各设置有一个由伺服机构控制的可折叠舵面控制机构;可折叠V型尾翼设置于主机身尾端。无人机弹出后机翼前缘、无人机可折叠舵面控制机构、V型尾翼在弹性作用下自动打开,使得柔性翼面展开。本发明采用柔性翼面设计使得折叠无人机可以获得更大的机翼面积,并且获得更高的气动效率,提高升力系数,降低无人机的最小平飞速度,使其具有更好的机动性。
