    摘要: A pitch angle indicator system indicates a pitch angle of blades of a propeller of a marine propulsion unit. A mechanical link couples at least one of the blades to a first end of a first rod. An indicator is coupled to a second end of the first rod. The mechanical link is configured to convert a change in the pitch angle into a rotation of the first rod about its longitudinal axis. The indicator is configured to provide an indication of the amount of rotation of the first rod about the longitudinal axis.

    摘要: The invention relates to a method for the operation of a marine propeller (1) comprising the following steps: - detection, by means of a sensor (11), of noise on a solid body (1, 4, 8) caused by gas cavitation and/or pseudocavitation, - transmission of a measurement signal of the sensor (11) by means of a contactless transmission method from the sensor (11) to a signal processing unit, and - generation of control commands by the signal processing unit depending on the received measurement signal to change the propeller speed by means a drive motor and/or to change the angle of attack of the blade of the marine propeller (1) by means of an actuator.
