The invention discloses an oil-electric hybrid unmanned aerial vehicle power system, and relates to the technical field of unmanned aerial vehicles and aircrafts. Through the cooperation design of coaxial direct drive and direct connection of the propeller, the engine and the direct-current permanent magnet motor, the power-to-weight ratio is simple, reliable and durable in structure and extremely high in power-to-weight ratio, the fuel oil engine and the permanent magnet direct-current motor are matched to form an oil-electricity hybrid power system, the permanent magnet direct-current motor can start the engine and convert redundant power into electric energy to charge a storage battery, and the power-to-weight ratio of the power-to-weight ratio is greatly improved. The direct-current permanent magnet motors can change the torque mixed into the engines under the regulation and control of the direct-current bidirectional electronic speed controller, so that the rotating speed of the propellers can be precisely regulated and controlled, three purposes are achieved, the engines with different displacements can be matched with the direct-current permanent magnet motors with corresponding powers and different power ratios, and the multi-rotor aircraft can be applied to unmanned aerial vehicles and multi-rotor aircrafts with different models. And through cooperation of the engines with different powers and the direct-current permanent magnet motor, different ratios of precise control and speed regulation ranges can be combined.
本发明公开了一种油电混动无人机动力系统,涉及无人机,飞行器技术领域。本发明通过螺旋桨、发动机、直流永磁电机,使用同轴直驱直连的配合设计,其结构简单、可靠、耐用、功重比极高,其中燃油发动机和永磁直流电机,配合形成油电混动系统,永磁直流电机既能启动发动机又能将多余的动力转换成电能给电瓶充电,直流永磁电机受到直流双向电调的调控可改变混入发动机的扭矩,故可精准调控螺旋桨的转速,进而构成了一机三用,不同排量的发动机可配合相应功率的直流永磁电机,不同功率的配比,可用于不同型号的无人机及多旋翼飞行器,且通过不同功率的发动机和直流永磁电机配合,可组合不同的精准控制与调速范围的配比。
