The invention discloses a long-endurance tilt-rotor unmanned aerial vehicle based on oil-electric hybrid power. The long-endurance tilt-rotor unmanned aerial vehicle adopts an aerodynamic layout in which a tandem oil-electric hybrid power device, a three-rotor system and a wing body are fused. When the unmanned aerial vehicle takes off vertically, the battery is used for independently providing power for the unmanned aerial vehicle, after the two groups of power devices tilt to a level flight state, the engine starts to work and provides power together with the battery, enough endurance time is ensured, and the power device at the tail of the fuselage can assist in adjusting the attitude of the unmanned aerial vehicle at the stage and ensure the stability of the flight process. The unmanned aerial vehicle can achieve the basic vertical take-off and landing function and the high cruising speed, and further has the advantages of being long in endurance time, large in loading space, more stable and safer in the level flight stage and the like.
本发明公开了一种基于油电混合动力的长航时倾转旋翼无人机,采用串联式油电混合动力装置、三旋翼系统和翼身融合的气动布局。垂直起飞时,使用电池单独为无人机提供动力,当前两组动力装置倾转至平飞状态后,发动机开始工作,与电池共同提供动力,保证足够的续航时长,此阶段机身尾部的动力装置可以辅助调节无人机的姿态,确保飞行过程的稳定性。本发明无人机可以实现除了基本的垂直起降功能和巡航速度快以外,还具备续航时间长,装载空间大,平飞阶段更稳定安全等优势。
