SIMULATION OF RUNNING ATTITUDE AND RESISTANCE OF A HIGH-SPEED CRAFT USING DATABASE OF THREE-COMPONENT HYDRODYNAMIC FORCES

In this paper, the authors propose a method to assess the performance of a high-speed semi-planing craft using a database of the measured three-component hydrodynamic forces (drag, lift and moment) acting on the model in a towing test. A computer program to simulate its running attitude and resistance using the database is developed. The simulated results are in good agreement with the experimental results. Using this method the effects of the length/beam ratio, hull shape, loading condition and appendage of the craft on the attitude and resistance, and the scale effect between a ship and its scale model are investigated. On this basis of the study is is concluded that the simulation procedure will offer more useful information than a conventional resistance test, In the design stage of a high-speed craft.
