A Powering Method for Planing Ships with Water Jet Pump

Abstract

In powering for planing ships with water jet pupm, we have to pay attention especially to the following two points. One, hull attitude of the ships much affects its hull resistance. The other, water jet pump still has some issues to be cleared such as hull and water jet pump interaction. These make the powering for the ships difficult, and the powering method for such ships has not yet been established. This paper proposes a powering method based on model test on each of hull and water jet pump, and its effectiveness is evaluated by applying it to full scale ships.
