The invention discloses a bionic airfoil of a flapping-wing air vehicle and a folding flapping structure of the bionic airfoil, and relates to the field of wings and driving structures of flapping-wing air vehicles. Flapping and wing unfolding of the flapping-wing aircraft are achieved through a driving element, the bionic flapping-wing aircraft comprises a fuselage, a pair of folding wings and a V-shaped empennage, and the pair of folding wings and the V-shaped empennage are symmetrically distributed on the two sides of the fuselage of the flapping-wing aircraft respectively; each folding wing comprises a wing rod connected with the fuselage and a wing membrane connected to the wing rod; the wing rods comprise the first wing rod, the second wing rod, the first outer wing rod and the second outer wing rod, folding is achieved through a simple and light structure, the increased mass is small, and generated inertia force is small; the bionic flapping wing aircraft further comprises a motor fixedly installed on the aircraft body, a sixth gear keeping linkage with the motor, a second connecting rod connected between the sixth gear and the first wing rod, and a first connecting rod connected between the sixth gear and the connecting piece. The three-section wing of the structural design is extremely similar to the folding of the wings when the domestic pigeon flies, and the bionic property is high.
本发明公开了一种扑翼飞行器的仿生翼面及其折叠扑动结构,涉及扑翼飞行器的机翼及驱动结构领域。采用一个驱动元件实现扑翼飞行器扑动和机翼展开,所述仿生扑翼飞行器包括机身、一对折叠机翼、V型尾翼,一对折叠机翼和V型尾翼分别对称的分布在扑翼飞行器的机身两侧;所述折叠机翼包括与机身相连的翼杆和以及连接在翼杆上的翼膜;所述翼杆包括机翼杆一、机翼杆二、外翼杆一和外翼杆二,采用简单轻量的结构实现了折叠,所增加的质量小,产生的惯性力小;所述仿生扑翼飞行器还包括固定安装在所述机身上的电机,与电机保持联动的齿轮六,连接在齿轮六和机翼杆一之间的连接杆二,以及连接在齿轮六和连接件之间的连接杆一。本结构设计的三段翼与家鸽飞行时翅膀的折叠极为相似,仿生性较强。
