The invention discloses a rotor wing pressure measuring system based on an air slip ring. The rotor wing pressure measuring system comprises a rotor wing pressure measuring system stator and a rotor wing pressure measuring system rotor, the rotor wing pressure measuring system stator is composed of a supporting rod, an air slip ring stator and a servo motor stator, and the supporting rod is fixedly connected with the air slip ring stator and the servo motor stator; the rotor wing pressure measuring system rotor is composed of a servo motor rotor and an air slip ring rotor, and the servo motorrotor is fixedly connected with the air slip ring rotor through a connecting piece; the air slip ring rotor is connected with the supporting rod through a bearing; a rotor wing with a pressure measuring hole machined in the surface is fixedly connected with the servo motor rotor, a pressure measuring hose is led out from the root of the rotor wing and connected with an air slip ring rotor air pipeconnector, the air slip ring rotor air pipe connector is communicated with an air slip ring stator air pipe connector through an air path, and the air slip ring stator air pipe connector is connectedwith a pressure measuring system through a hose. According to the system, a pressure signal is transmitted to the static air slip ring stator in the rotating process of the rotor wing, so that the data of the surface pressure of the rotor wing in motion are recorded.
