In this study, the effects of hydrodynamic interceptors on a high-speed vessel were investigated to identify the operating principle based on experiments. Model tests were performed using a high-speed towing carriage. The resistance, trim and rise of Center of Gravity (CG) of the high-speed vessel were measured for various ship speeds and interceptor heights. As the interceptor height increased, the trim and rise of CG were reduced. In order to quantitatively analyze these phenomena, the pressure at the stern bottom was measured using tactile sensors. The reliability of the measured results from the tactile sensors was verified through repeat tests. The pressure on the stern bottom increased in proportion to the interceptor height, as the interceptor partially blocked the flow there. Then, the trim was reduced. However, as the ship speed increases, the pressure at the location close to the interceptor decreases when the interceptor height is small, leading to increased trim. Therefore, the interceptor height for running attitude control should be carefully determined considering multiple factors in the operating condition of the high-speed planing hull.

在这项研究中，研究了流体动力拦截器对高速船的影响，以根据实验确定工作原理。使用高速牵引车进行模型测试。针对各种船速和拦截高度，测量了高速船的重心（CG）的阻力，纵倾和纵倾。随着拦截器高度的增加，CG的修剪和上升减小。为了定量分析这些现象，使用触觉传感器测量了船尾底部的压力。通过重复测试验证了来自触觉传感器的测量结果的可靠性。船尾底部的压力与拦截器高度成正比，因为拦截器部分地阻塞了那里的水流。然后，减少了修剪。但是，随着船速的增加，当拦截器高度较小时，接近拦截器的位置处的压力会降低，从而导致修剪增加。因此，在高速滑行船体的操作条件下，应综合考虑多种因素，仔细确定用于控制行驶姿态的拦截器高度。
