The invention discloses a cross-medium aircraft power device based on blade tip jet rotors and a working method thereof.The power device comprises a gas compressor, an annular motor, rotor blades and a power motor, gas flow channels are formed in the rotor blades and connected with a gas outlet of the gas compressor, and the power motor drives the gas compressor to conduct compressed gas jet or water pumping; lift force or thrust force is provided; and the annular motor is arranged at the joint of the gas compressor and the rotor blade and controls the rotor blade to rotate around the fixed shaft so as to realize the functions of total pitch change and periodic pitch change of the rotor. The power device disclosed by the invention can provide power for the aircraft in water and air media in different driving modes, and the problems that an existing cross-medium aircraft is provided with two sets of independent power devices, unnecessary weight increment is caused, and the same set of power device is difficult to achieve better efficiency at the same time when working in the two media in the same driving mode are solved. In addition, the rotatable blades can be used as an aircraft control surface underwater, so that the underwater maneuverability of the aircraft is enhanced.
本发明公开了一种基于桨尖喷气旋翼的跨介质飞行器动力装置及其工作方法,该动力装置包括压气机、环形电机、旋翼叶片和动力电机,旋翼叶片内设气体流道并与压气机气体出口相接,动力电机驱动压气机进行压气喷出或泵水,以提供升力或推力;环形电机设于压气机与旋翼叶片的连接处,控制旋翼叶片绕固定轴旋转以实现旋翼总距改变与周期变距功能。本发明公开的动力装置能够在水空两介质中以不同驱动方式为飞行器提供动力,解决了现有跨介质飞行器配备两套独立动力装置带来不必要增重,以及同一套动力装置以相同的驱动方式在两介质中工作难以同时达到较优效率的问题。此外可旋转的叶片还可在水下作为飞行器操纵面,增强飞行器水下机动性。
