摘要：The purpose of this study is to propose the propulsive performance estimation method for high-speed planing craft with outboard engine. In order to understand the characteristics of propulsion, a fully captive model test with propulsion is carried out. Based on the results, an estimation method taking the self-propulsion factors, which are the changes of hydrodynamic forces acting on hull with lower-hull of outboard engine caused by propeller action, the effective wake fraction and the relative rotative efficiency, is proposed. Using the proposed method, running attitude, thrust (or THP), crank shaft torque (or BHP), maximum forward speed and fuel consumption of a real craft are estimated. As the results, it is found that the effective wake fraction and the relative rotative efficiency of the self-propulsion factors are significant to estimate maximum forward speed of the craft.
