The inflatable flapping wing mechanism comprises a head, a fuselage and a tail, wing assemblies are arranged on the two sides of the fuselage, each wing assembly is composed of an inner-section wing, a plurality of middle-section wings and an outer-section wing, the inner-section wings are connected with a driving mechanism in the fuselage through connecting pieces, and the outer-section wings are connected with a driving mechanism in the fuselage through connecting pieces. The inner-section wing, the middle-section wing and the outer-section wing are connected through the elastic piece sets, and ideal flexible folding and unfolding deformation of the wing assembly in the flapping process is achieved through the specific assembling mode of the elastic piece sets and the different elastic rigidities of the elastic pieces. Each section of wing is composed of an inflatable airbag module, an airbag cavity is formed in the fuselage, and the purposes of reducing the weight of the flapping wing and improving the effective load capacity are achieved by inflating light gas such as helium. The inflatable wings and the fuselage can realize light weight of a large-scale structure, have higher aerodynamic efficiency, provide certain lift force, and can effectively improve the flight time and the effective load of the flapping wing mechanism.

    本发明公开了一种具有多段柔性机翼的充气式扑翼机构,包括头部、机身、尾部,机身两侧设有机翼组件,机翼组件均由内段机翼、多个中段机翼、外段机翼组成,内段机翼通过连接件与机身内部的驱动机构连接,内段机翼、中段机翼、外段机翼之间均通过弹性片组连接,通过弹性片组的特定装配方式及各弹性片的不同弹性刚度使机翼组件在扑动过程中实现理想的柔性折展变形。各段机翼均由充气气囊模块构成,机身内部有气囊腔体,通过充入轻质气体如氦气以实现减轻扑翼重量、提升有效荷载能力的目的。本发明充气式的机翼和机身可以实现大尺度结构的轻量化,具备较高的空气动力学效率,并提供一定的升力,能有效提高扑翼机构的飞行时间和有效负载。
