The invention discloses a flapping wing device, which belongs to the technical field of aviation and comprises a body and a flapping wing movably connected to the body. Each flapping wing is composed of a front beam (1), a rear beam (2), middle beams (3), a main rudder (4), wing ribs (5) and skins, the middle beams (3) are arranged on the upper and lower surfaces of the wing ribs (5) through the main rudders (4) to form double middle beams, and the double middle beams are movably connected with the upper and lower skins respectively and drive the upper and lower skins in turn to form wing surfaces which can be turned into convex wing surfaces in turn and synchronously generate incident flow during forward and backward sweep swing of the flapping wings so as to form a wing surface pressure difference; the flapping wings are driven to stably flap, so that the efficiency is improved. The trapezoidal flapping wing formed by adopting a semi-rigid structure is compact and firm, the multi-degree-of-freedom flapping efficiency formed by active front-back sweep swing and wing surface pressure is relatively high, and the application of a large-scale flapping-wing aircraft is promoted.

    本发明公开一种扑翼装置,属于航空技术领域,包括机体和活动连接在所述机体的扑翼。所述扑翼由前梁(1)、后梁(2)、中梁(3)、主舵(4)、翼肋(5)和蒙皮构成,所述中梁(3)通过所述主舵(4)设在所述翼肋(5)上下面构成双中梁,分别活动连接且轮流驱动上下的所述蒙皮,构成可轮流变为外凸翼面,同步在所述扑翼前后掠摆动中产生迎流而形成翼面压强差,驱动所述扑翼稳定扑动提高效率。本发明采用半刚性结构构成的梯形扑翼紧凑牢靠,且主动前后掠摆动与翼面压强形成多自由度扑动效率较高,促进大型扑翼飞行器的应用。
