Abstract
For the high-speed ship with hydrofoil, it is important to grasp the mutual interference between its hydrofoil and hull. In this study, effects of the state of hydrofoils and velocity on the hull were fluid-dynamically investigated through the numerical calculation by means of Rankine source method using a Wigley model with two hydrofoils. Before considering the model with hydrofoils, the attitude change of a hull without hydrofoils during traveling in high-speed was examined. For the high-speed ship, various measuring systems have been conceived due to the large change in its attitude. The Wigley model has been used for the numerical calculation when considering the attitude change in the medium- and low-speed regions. In this study, resistance tests without constraining the sinkage and trim were conducted using a Wigley model in the high-speed region around Fn=1.0, which have not been usually conducted. The attitude changes were compared with the numerical calculation results by the Rankine source method. The wave making resistance and attitude change of the Wigley model with hydrofoils were also calculated. 12 refs., 10 figs.
