The invention belongs to the technical field of unmanned aerial vehicles, and particularly relates to a multi-rotor unmanned aerial vehicle with long cruising capacity. The multi-rotor unmanned aerialvehicle comprises a main rotor power device, an electric four-rotor assembly, a flight controller and a rack. The main rotor wing power device comprises an engine, a driving chain wheel, a first driven chain wheel, a second driven chain wheel, a tensioning chain wheel, a main chain, a left chain, a right chain, a left main rotor wing and a right main rotor wing. The electric four-rotor assembly comprises a battery, a left front propeller with a motor, a right front propeller with a motor, a right rear propeller with a motor and a left rear propeller with a motor. The electric four-rotor assembly is used for generating a part of lift force and cooperating with the flight controller to control the flight attitude. The left main rotor wing and the right main rotor wing are the same in rotating speed structure and are arranged in a bilateral symmetry mode, and most lift force of the multi-rotor-wing aircraft is generated by the left main rotor wing and the right main rotor wing. The unmanned aerial vehicle has the advantages of high cruising ability, high efficiency, light weight and the like.

    一种长巡航能力多旋翼无人机,属于无人机技术领域,尤其涉及一种多旋翼无人机,包括主旋翼动力装置、电动四旋翼组件、飞行控制器和机架。主旋翼动力装置包括发动机、主动链轮、第一从动链轮、第二从动链轮、张紧链轮、主链条、左链条、右链条、左主旋翼、右主旋翼。电动四旋翼组件包括电池、左前带电机的螺旋桨、右前带电机的螺旋桨、右后带电机的螺旋桨、左后带电机的螺旋桨。电动四旋翼组件用来产生一部分升力和配合飞行控制器进行飞行姿态的控制。左主旋翼和右主旋翼转速结构相同,左右对称布置,本多旋翼飞行器的大部分升力由左主旋翼和右主旋翼产生。本发明具有续航能力强,效率高,重量轻等优点。
