The invention discloses a tilting hybrid power fly-by-wire vertical take-off and landing fixed-wing unmanned aerial vehicle. The unmanned aerial vehicle comprises a body, a tail, a rotor wing assembly, a tilting assembly and a power assembly, the power assembly is installed in the body and comprises an oil tank, an engine, a generator and a battery, an output shaft of the engine drives the generator to work, and the battery is connected with the generator and a tilting motor through cables. By adopting the technical scheme of combining a hybrid power system and a tilting mechanism, the characteristic of high energy density of a fuel engine can be fully utilized by the unmanned aerial vehicle, so that the flight time and the hovering time are greatly prolonged, and the performance is optimized and improved; meanwhile, double backups are provided for an energy system, so the unmanned aerial vehicle can normally fly even if the engine breaks down; in the fixed-point hovering process, onlythe battery is used for supplying power when a common vertical fixed-wing aircraft hovers, the energy of the generator is increased, and the power output of the battery is reduced, so the hovering time can be prolonged by more than one time compared with hovering time of a common conventional fixed-wing unmanned aerial vehicle.
本发明公开了一种倾转混动电传垂直起降固定翼无人机,包括:机身、机尾、旋翼组件、倾转组件和动力组件,动力组件安装于机体内,包括油箱、发动机、发电机和电池,发动机的输出轴驱动发电机工作,电池通过线缆分别与发电机和倾转电机相连接。采用了混动系统与倾转机构相结合的技术方案,能够使无人机充分利用燃油发动机能量密度高的特点,使得飞行时间和悬停时间都大大延长,性能得到优化提升;同时也对能源系统有双备份,即便发动机出现故障也能正常飞行;在定点悬停过程中,一般垂起固定翼飞机悬停的时候只用电池供电,而本发明中增加了发电机的能量,减少了电池电能的输出,因而能增加悬停时间,比一般常规固定翼无人机悬停时间增加一倍以上。
