The invention discloses a single-rotor helicopter with fans balancing fuselage rotation, belongs to the field of aviation industry, and provides a single-rotor helicopter which is large in load due to a single rotor, and an engine of the helicopter drives a main rotor upwards through bevel gear transmission to generate lift force to lift the weight of the whole helicopter; meanwhile, the fan is driven downwards to rotate reversely to balance autorotation of the machine body; as the main rotor shaft and the fan shaft are on the same vertical center line of the aircraft, the control is convenient and easy. The unmanned aerial vehicle can be applied in a multifunctional mode, and the working principle of the unmanned aerial vehicle can be simply and conveniently explained. An existing multi-rotor unmanned aerial vehicle is good in fuselage self-balance, easy to control and small in total load. A traditional single-rotor unmanned aerial vehicle with a tail rotor is large in load, but is difficult to control. The unmanned aerial vehicle integrates the advantages of two existing unmanned aerial vehicles and avoids the defects of the two unmanned aerial vehicles, so that the performance and the control of the whole unmanned aerial vehicle are greatly improved; the engine selects the motor when the load is small, and selects the oil-driven engine when the load is large, so that the helicopter is suitable for industrial and military helicopters, and the application prospect is wide.
本“风扇平衡机身自转的单旋翼直升机”属于航空工业领域,因是单旋翼所以荷载较大,其发动机通过锥齿轮传动向上带动主旋翼产生升力抬举整机重量;同时向下带动风扇反转平衡机身自转;因主旋翼轴和风扇轴同在本机垂直中心线上,所以操控方便容易。本机可多功能应用,为简便说明其工作原理,本说明以无人机应用重点描述。现有“多旋翼无人机”机身自平衡好,操控容易,但总荷载较小;而传统“单旋翼带尾桨无人机”虽然荷载较大,但操控困难。本发明无人机集现有两种无人机之优点,又避免了两者缺点,因此性能和整机操控都获得较大提升;至于发动机,荷载较小时选电动机,荷载较大时选油动发动机,总之适用做工业用和军用二种直升机,应用前景广阔。
