The invention relates to the technical field of unmanned aerial vehicles, in particular to a double-layer-wing unmanned aerial vehicle. The aircraft comprises a carrier and a plurality of flight mechanisms; the flight mechanisms surround the carrier and are symmetrically arranged with the carrier as the center, each flight mechanism comprises an extension arm, a driving device and a translation wing, and the two ends of each extension arm are connected with the carrier and the driving device respectively; central shafts are arranged on the upper side and the lower side of the driving device respectively, translational wings connected with the central shafts in a matched mode are arranged on the central shafts, and the driving device is connected with the translational wings on the two central shafts through asynchronous mechanisms respectively, so that the two translational wings are driven to do opening and closing movement on the central shafts oppositely. The unmanned aerial vehicleis reasonable in structure, and through vertical reciprocating motion of the two translation wings, air generates pressure difference between the front side curved surface and the rear smooth surfaceof the turbulent flow wing surface when the translation wings ascend, so that the translation wings are promoted to rotate in one direction; when the translational wing descends, a vertical upward acting force is generated between the flapping wing surface and air, so that the unmanned aerial vehicle obtains lifting force to achieve the flying purpose.
本发明涉及无人机技术领域,具体指一种双层翼无人机;包括载体和若干飞行机构,所述若干飞行机构围绕载体并以其为中心对称设置,飞行机构包括展臂、驱动装置和平动翼,展臂的两端分别连接载体和驱动装置;所述驱动装置的上下两侧均设有中心轴,中心轴上设有与其配合连接的平动翼,所述驱动装置通过异步机构分别连接两个中心轴上的平动翼,从而驱动两个平动翼在中心轴上相对地进行张合运动;本发明结构合理,通过两个平动翼的上下往复运动,平动翼在上升时空气对扰流翼面前侧曲面和后部平滑面之间产生压力差从而促使平动翼单向旋转;平动翼在下降时扇动翼面与空气之间产生竖直向上的作用力,使无人机获得升力实现飞行目的。
