The invention discloses an oil-electric hybrid multi-rotor unmanned aerial vehicle which comprises a vehicle body and further comprises a plurality of pairs of vehicle arms which are connected to the vehicle body in a central symmetry mode with the vehicle body as the midpoint. A fuel engine is mounted in the middle of any arm, and a motor is mounted at the tail end, away from the fuselage, of any arm; and the fuel engine and the motor are respectively connected with rotor wings. All the rotors and the vehicle body of the oil-electric hybrid multi-rotor unmanned aerial vehicle have the central symmetry relation and also have the axial symmetry relation, the attitude change of the vehicle body can be realized and the normal flight of the unmanned aerial vehicle can be ensured by adjusting the working state of one or more rotors, and the attitude adjustment flexibility is improved; and meanwhile, the long-time posture adjustment of the motor can be avoided, and the endurance time of the motor is prevented from being influenced. Besides, if the fuel engine of a certain rotor has a fault, the stress balance of the vehicle body and the normal endurance or safe landing of the unmanned aerial vehicle are ensured by adjusting the motor of the same rotor or adjusting the other rotor located on the same straight line as the rotor, and the flight quality is improved.
本发明公开了一种油电混动多旋翼无人机,包括机身,还包括多对以机身为中点中心对称连接于机身的机臂;任一机臂的中部安装有燃油发动机,任一机臂远离机身的末端安装有电动机;燃油发动机和电动机分别连接有旋翼。上述油电混动多旋翼无人机的全部旋翼与机身既具有中心对称关系,也具有轴对称关系,调整其中一个或几个旋翼的工作状态可以实现机身姿态变化且保证无人机正常飞行,提高姿态调节的灵活性,同时也能避免电动机长时间进行姿态调节,避免影响电动机的续航时间。此外,若某一旋翼的燃油发动机故障时,通过调节同一旋翼的电动机或者调节与前述旋翼位于同一直线的另一旋翼,保证机身受力平衡、无人机的正常续航或者安全降落,提高飞行质量。
