The invention belongs to the technical field of helicopter rotors, and discloses a variable-pitch rotor structure and a control method thereof. The variable-pitch rotor structure comprises a motor, acentral propeller hub, a propeller clamp, a variable-pitch shaft and blades; wherein the blades are installed on the propeller clamp, the propeller clamp is connected with the central propeller hub through the variable-pitch shaft, and the central propeller hub is installed on the motor; a preset included angle is formed between the variable-pitch shaft and the rotor plane, the preset included angle is smaller than 90 degrees, the propeller clamp can freely rotate around the variable-pitch shaft by the preset angle, control over the large multi-rotor aircraft is effectively simplified, and a simple and effective method is provided for large-scale electric multi-rotor aircrafts.
本发明属于直升机旋翼技术领域,公开了一种可变距旋翼结构及其控制方法,所述旋翼结构包括:马达、中央桨毂、桨夹、变距轴及桨叶;其中,桨叶安装在桨夹上,桨夹通过变距轴与中央桨毂连接,中央桨毂安装在马达上;变距轴与旋翼平面存在预设夹角,所述预设夹角小于90度,且桨夹可以绕变距轴自由旋转预设角度,有效简化了大型多旋翼飞行器的操控,为电动多旋翼大型化提供了一种简单有效的方法。
