The invention discloses a fixed-pitch variable-rotating-speed double-rotor tandem type unmanned helicopter which is composed of a helicopter body assembly, power assemblies and posture adjusting assemblies, the power assemblies and the posture adjusting assemblies are arranged on the helicopter body front and back, and the posture adjusting assemblies and the power assemblies are arranged in a one-to-one correspondence mode. The propeller pitch of the propeller is not changed, the lift force is changed by adjusting the rotating speed of the motor, the posture is changed by tilting the swash plate, the structure is simplified, the weight is reduced, the waste resistance is reduced, the cost is reduced, the reliability is improved and the maintenance is simple.
本发明公开了一种定桨距变转速双旋翼纵列式无人直升机,由机体组件和前后安置于机体上的动力组件和调姿组件构成,调姿组件与动力组件一一对应设置。本发明中螺旋桨的桨距不变,靠调节电机转速改变升力,靠倾转斜盘角度改变姿态,结构简化、重量减轻、废阻减小、成本降低、可靠性提高、维护变简单。
