The invention provides a propeller operation monitoring device, a propeller and an airplane. The propeller operation monitoring device comprises a propeller cap, a mounting disc and an annular antenna, the propeller cap is used for being installed on a propeller hub, the propeller cap and the propeller hub are matched to form a containing cavity, and the cross section of the inner wall face of the propeller cap is circular. The mounting disc is used for being mounted on a propeller hub and located in the containing cavity, the mounting disc is in a disc shape, and the mounting disc and the propeller hub are arranged on the same rotating shaft; the mounting disc is provided with a sensor group, a main control circuit and an antenna radio frequency module, and the sensor group and the antenna radio frequency module are electrically connected with the main control circuit; the annular antenna is arranged around the inner wall face of the propeller cap, located at the position, away from the mounting disc, of the propeller cap and electrically connected with the antenna radio frequency module. The propeller is applied to the propeller operation monitoring device. The propeller is applied to the aircraft. According to the propeller operation monitoring device, the antenna circuit is not prone to being damaged in the high-speed rotation state of the propeller, and signal interference can be reduced.

    本发明提供一种螺旋桨运行监控装置、螺旋桨和飞机,该螺旋桨运行监控装置包括桨帽、安装盘和环形天线;桨帽用于安装在螺旋桨桨毂上,桨帽与螺旋桨桨毂配合形成容纳腔,桨帽的内壁面的横截面呈圆形设置;安装盘用于安装在螺旋桨桨毂上且位于容纳腔内,安装盘呈圆盘状,安装盘与螺旋桨桨毂同转轴设置;安装盘设置有传感器组、主控电路和天线射频模块,传感器组和天线射频模块均与主控电路电连接;环形天线沿桨帽的内壁面环绕设置,且位于桨帽远离安装盘的位置,环形天线与天线射频模块电连接。该螺旋桨应用该螺旋桨运行监控装置。该飞机应用该螺旋桨。应用本发明的螺旋桨运行监控装置在螺旋桨高速旋转状态不易损坏天线线路且可减少信号干扰。
