Abstract
Official abstract text for this publication.
Disclosed is a method of decreasing pressure fluctuation induced on a surface of a hull due to propeller cavitation by using real-time vibration information and adjusting rotation angles of two propellers of a twin-propeller ship.
First claim
Opening claim text (preview).
What is claimed is: 1. A method of decreasing pressure fluctuation by using real-time vibration information and adjusting rotation angles of two propellers of a twin-propeller ship, the method comprising: measuring, by a vibration sensor system at step S0, a vibration signal for each relative rotation angle of the two propellers, each relative rotation angle indicating a difference in rotation angles of the two propellers, and outputting information on the measured vibration signa…
