The invention discloses a propeller device of a vertical take-off and landing aircraft, belongs to the technical field of production of electric vertical take-off and landing aviation instruments, and aims to solve the technical problem of how to increase the lift force of a single propeller device of the electric vertical take-off and landing aircraft. According to the technical scheme, the power of a motor is increased, the rotating speed of a propeller is increased, the number of propeller blades is increased, the lengths of the propeller blades are increased, idler wheels are installed at the tail ends of the propeller blades, and the propeller blades rotate along a fixed annular track. The motor is arranged above the cross-shaped annular track, the transmission shaft downwards penetrates through the track, the turntable is arranged at the lower end of the transmission shaft, the roller is arranged below the track and corresponds to the track, and the blades and the roller roll and rotate below the track. The device can be divided into an anticlockwise rotating propeller device and a clockwise rotating propeller device. The device is suitable for helicopters and unmanned aerial vehicles of electric vertical take-off and landing aircrafts.
一种垂直起降航空器的螺旋桨装置,属于电动垂直起降航空器械生产技术领域,所要解决的技术问题:如何增加电动垂直起降航空器单台螺旋桨装置的升力。技术方案要点是:增加电机的功率、增加螺旋桨的旋转速度、增加螺旋桨桨叶的数量、增加桨叶的长度,给螺旋桨桨叶末端安装滚轮,让桨叶沿着固定的环形轨道旋转。滚轮安装在桨叶末端,桨叶叶柄安装在转盘上,电机安装在十字环形轨道上方,传动轴向下穿过轨道,传动轴下端安装转盘,滚轮在轨道下面与轨道相对应,桨叶和滚轮在轨道下方滚动、旋转。该装置可分为逆时针和顺时针方向旋转螺旋桨装置。该装置适用于电动垂直起降航空器的直升机和无人机。
