<p>PURPOSE:To effectively reduce the rock of a hull by the reaction force of jet flow by arranging thrustors in which the direction of jet flow is parallel and reverse at the front and rear parts of the hull and controlling the speed of the jet flow of the thrustors according to the output signal of a wave sensor. CONSTITUTION:Thrustors 2a-2d are installed, at the position where the direction of jet flow is parallel and reverse and said jet flow does not interfere each other, at the front and rear parts of a hull. In each thrustor, the speed of jet flow can be adjusted freely by a controller 4 according to the signal of a wave sensor 3. The rocking of the hull can be effectively reduced by the reaction force in the case when each jet flow is curved at right angles by waves.</p> |
