The invention relates to a coaxial wing sail type rotor wing structure and a control method thereof. The coaxial wing sail type rotor wing structure comprises an upper rotor wing, a lower rotor wing, a middle rotor wing and a wing sail, the upper rotor wing comprises four upper rotor wing blades, the lower rotor wing comprises four lower rotor wing blades, and the middle rotor wing comprises four middle rotor wing blades; all the upper rotor blades are connected to one end of the propeller hub inner shaft, and all the lower rotor blades are connected to the other end of the propeller hub inner shaft; the propeller hub inner shaft is sleeved with a propeller hub outer shaft, and all the middle rotor blades are connected with the propeller hub outer shaft; a wing sail is connected between the corresponding upper rotor blade and lower rotor blade; each rotor blade is provided with a trailing edge winglet and a trailing edge winglet actuator; wing sail actuators are arranged on the upper rotor blade and the lower rotor blade; a rotor azimuth angle sensor is arranged on the propeller hub outer shaft; and the wing sail actuator, the trailing edge winglet actuator and the rotor azimuth angle sensor are connected with the control module. The rotors are simple in structure, easy to control, high in control precision and good in stability, and the helicopter does not need to incline for attitude change.

    本发明涉及一种共轴带翼帆式旋翼结构及其控制方法,包括上旋翼、下旋翼,中间旋翼和翼帆;上旋翼包括四个上旋翼桨叶,下旋翼包括四个下旋翼桨叶,中间旋翼包括四个中间旋翼桨叶;所有的上旋翼桨叶连接于桨毂内轴的一端,所有的下旋翼桨叶连接于桨毂内轴的另一端;桨毂内轴上套设桨毂外轴,所有的中间旋翼桨叶与桨毂外轴连接;相对应的上旋翼桨叶和下旋翼桨叶之间连接翼帆;各旋翼桨叶上均设有后缘小翼和后缘小翼作动器;上旋翼桨叶和下旋翼桨叶上设有翼帆作动器;桨毂外轴上设有旋翼方位角传感器;翼帆作动器、后缘小翼作动器和旋翼方位角传感器连接控制模块。旋翼结构简单,易于控制,无需使直升机倾斜进行姿态改变,控制精度高且稳定性好。
