Resistance test of high-speed ship by means of attitude control method. Part 2; Shisei seigyo hoshiki ni yoru kosokutei no teiko shiken. 2

Abstract

The previous paper has proposed a resistance test method by controlling the attitude of a high-speed model ship using a personal computer without making a data base. For this method, the fluid force acting on the hull of model ship is measured, to change its attitude based on the measurement, and then, the fluid force is measured again, to change the attitude again. The traveling attitude is created by repeating this, to measure the force acting on the hull. Since the attitude is changed by calculating using the fluid force measured, various factors can be considered in the calculation process. For example, a test with an arbitrary displacement in an arbitrary position of center of gravity can be conducted in spite of actual displacement and position of center of gravity of the model ship. A test for a high-speed ship was conducted through this method, to obtain nearly satisfactory results compared with a usual resistance test. Occasionally, a lot of repetitions were required to satisfy the balancing condition of the force. In this study, the improvement of testing efficiency has been planned by modifying the analyzing program. 5 refs., 7 figs., 1 tab.
