The invention discloses a double-layer autorotation rotor wing lifting device and relates to the technical field of aviation, in particular to a rotor wing lifting device. The device comprises an upper-layer rotor wing, a lower-layer rotor wing and a guide rod. The plurality of fins are uniformly arranged around a rotary disc; the front edges of all the upper-layer fins face the same direction; the lower-layer rotary disc is mounted on a sliding block through a rotating bearing, the sliding block is mounted on a guide rod, and the sliding block can flexibly slide up and down along the guide rod; the front edges of all the lower-layer fins face the same direction; the installation angle of the fin is between -1 degree and 4 degrees; the upper-layer rotor wing and the lower-layer rotor wingare driven by power to do reciprocating rectilinear motion, so that the wing blades rotate to generate a lift force. The device is simple and reasonable in structure, the rotating directions of the upper and lower fins are opposite, and the aircraft can vertically take off and land and can hover in the air when installed on the aircraft. The invention discloses a part of flight principle of largebirds, the wings mainly generate thrust when flapping upwards, so that the birds mainly generate lift force when flying forwards and flapping downwards, and meanwhile, a part of thrust can also be generated.
一种双层自转旋翼升力装置,涉及航空技术领域,尤其涉及一种旋翼升力装置,包括上层旋翼、下层旋翼和导杆;多个翼片均匀地安装在转盘的周围;所有上层翼片的前缘朝向同一个方向;下层转盘通过转动轴承安装在滑块上,滑块安装在导杆上,滑块能沿导杆灵活上下滑动;所有下层翼片的前缘朝向同一个方向;翼片安装角在-1°至4°之间;上层旋翼与下层旋翼在动力的驱动下作往复直线运动,导致翼片旋转而产生升力。本发明结构简单合理,上下翼片的旋转方向相反,安装在飞行器上,飞行器能垂直起降,还能在空中悬停。本发明揭示了大型鸟类的一部分飞行原理,翅膀上扑时主要产生推力,使鸟前飞,翅膀下扑时主要产生升力,同时也会产生一部分的推力。
