Japan, Sept. 16 -- YAMAHA MOTOR CO LTD has got intellectual property rights for 'SHIP PROPULSION SYSTEM AND SHIP.' Other related details are as follows:
Application Number: JP,2023-113303
Category (FI): B63H21/21,B63B39/00
Stage: PROBLEM TO BE SOLVED: To provide a ship propulsion system that can improve stability of a hull and improve riding comfort during waves, and a ship.SOLUTION: A ship propulsion system 102 comprises: a propeller 1 provided on a hull 101; a vertical motion sensor 2b which measures at least one of a vertical speed and a vertical acceleration of the hull 101; and a control part 4 that performs wave control including posture control for reducing vertical postural change of the hull 101 by temporarily reducing a ship speed at each timing of overcoming each wave on the basis of the measurement result of the vertical motion sensor 2b during waves. The control part 4 performs wave direction determination for determining whether the wave state relative to the hull 101 is heading wave or following wave on the basis of at least the measurement result of the vertical motion sensor 2b in wave control. The control part performs the posture control when determining by wave direction determination that the wave state is heading wave, and does not perform the posture control when determining by wave direction determination that the wave state is following wave.SELECTED DRAWING: Figure 6 (Grant)
