用プロペラ高次起振力軽減装置。 In order to reduce the high-order excitation force of the propeller at the stern, a pipe is provided that protrudes from the ship's hull to near the tip of the propeller blade of the propeller and has an air outlet at the tip, and is attached to the part of the ship's hull above the propeller. A high-order marine propeller, characterized in that it is provided with a pressure sensor for detecting external water pressure, and a control system capable of controlling the air blowing amount or air blowing time from the pipe based on the detection signal from the sensor. Excitation force reduction device.
