A Theoretical Study on High Speed Ship Hull Forms : Application for Practical Hull Forms

概要

論文の詳細を見る
When we design high speed displacement type ships, it is the most important to reduce her resistance. The faster a ship cruises, the larger wave making resistance becomes. This is the reason why designers want to search hull forms which give small wave making resistance. Moreover spray resistance is also large at high speed. And it is known from recent studies there is water head resistance in a ship which has a vertical stem and a transom stern. Hull forms which give minimum resistance components are studied, but obtained forms are strange and unrealistic. This report represents improvement of such strange forms and application for practical hull forms. The obtained hull form has small spray at the bow. And this form is enough to be realized.
