The invention provides a pure electric longitudinal double-rotor unmanned aerial vehicle system, and the system comprises a longitudinal double-rotor unmanned aerial vehicle platform, a flight controlunit, a power supply, a power supply management unit and a ground station unit. The longitudinal double-rotor unmanned aerial vehicle platform comprises a rack, a rotor system and a power system. Theflight control unit acquires attitude information of the unmanned aerial vehicle through a sensor and realizes attitude control through a PID controller; the power supply and power supply managementunit is connected with the power system and the flight control unit. The ground station unit and the flight control unit carry out data and instruction transmission. A pure electric power system is adopted, so the mechanical difficulty and the maintenance difficulty of the power system are greatly reduced, and environmental friendliness is achieved; the two rotor systems with opposite rotating directions are respectively arranged on the two rotor tower bases, the generated reaction torque can be mutually balanced, a tail rotor does not need to be independently designed, and the efficiency is higher; the loading capacity is more excellent; the take-off and landing requirement conditions are low, the crosswind disturbance resistance during hovering is excellent, and the large control allowance is achieved.
本发明提供了一种纯电动纵列双旋翼无人机系统,包括纵列双旋翼无人机平台、飞控单元、电源及电源管理单元以及地面站单元;纵列双旋翼无人机平台包括机架、旋翼系统以及动力系统;飞控单元通过传感器获取无人机的姿态信息,并通过PID控制器实现姿态的控制;电源及电源管理单元分别与动力系统以及飞控单元相连接,地面站单元与飞控单元进行数据及指令传输。本发明采用纯电动动力系统,大大简化动力系统机械难度和维修难度,并且更加环保;两个旋转方向相反的旋翼系统分别安装在两个旋翼塔座上,产生的反作用扭矩可以互相平衡掉,无需单独设计尾桨,效率更高;载重能力更为优秀;起降要求条件低,悬停时的抗侧风扰动能力优秀,具有较大的操纵余量。
