The embodiment of the invention provides an aircraft rotor power device. According to the device, blades are innovatively mounted on a flapping variable-pitch coupling rotating shaft of a middle connecting piece; a second end part through hole and a second end part groove for mounting the blade are formed in the flapping variable-pitch coupling rotating shaft; a propeller clamp lower seat is fixedly mounted on a middle rotating shaft of a rotary driving device; middle connecting pieces can be installed on the left side and the right side of the propeller clamp lower seat. The middle connectingpieces and the blades are fixedly mounted and connected through a propeller clamp upper cover. According to the device, a flapping variable-pitch coupling rotating shaft is designed; therefore, whenthe aircraft flies forwards, the lifting forces of the lifting force devices on the left and right sides in an advancing direction tend to be balanced, so that the vibration caused by unbalanced lifting forces is reduced substantially; since the flapping variable-pitch coupling rotating shaft and the blades are connected through the hinges, the blades always work at a high aerodynamic efficiency point in the 360-degree rotating direction under the variable-pitch effect, so that the aerodynamic efficiency of the device is greatly improved, energy consumption can be reduced, and the flight timecan be prolonged.
本发明实施例提供了一种飞行器旋翼动力装置,该装置创新性的将桨叶安装在中间连接件的挥舞变距耦合转轴上,并在挥舞变距耦合转轴上设置有安装桨叶的第二端部通孔和第二端部凹槽,桨夹下座固定安装在旋转驱动装置的中间转轴上,桨夹下座的左右两侧均可安装中间连接件,中间连接件与桨叶通过桨夹上盖固定安装连接,该装置通过设计了一个挥舞变距耦合转轴,使得飞行器在前飞的时候,升力装置在前进方向的左右两侧的升力趋于平衡,大大的减小了由于升力不平衡引起的振动,由于挥舞变距耦合转轴和桨叶之间通过铰链连接,在变距的作用下,桨叶在旋转360度方位始终工作在较高气动效率点上,大大提升了该装置的气动效率,可节约能耗及延长飞行时间。
