무인고속전차를 이용한 활주선형의 모형시험 기법 연구

초록

A planing hull speed is faster than a displacement type hull. Therefore, model test of a planing hull is difficult to use the main carriage. So, the high-speed carriage was installed in the Inha university towing tank. Model test for a planing hull using the high-speed carriage is measured force component and attitude of a model when a model was towed. In the captive model test method, the forces acting on a model fixed to the high-speed carriage are measured. This model test method is repeated until a hull attitude converges to zero lift and trim moment. So, this model test method is very difficult. In this research, trim free model test method is studied to reduce number of times of the model test.
