“…Then, Seok et al [16] conducted research on the effect of the interceptor on the pressure distribution. By the experiment of the high-speed displacement ship conducted in the towing tank, Pacuraru et al [17] found that the resistance can be reduced by up to 14% by the interceptor in the condition of high Froude numbers. In addition, in order to analyze the effect caused by the interceptor, new technologies have been applied to discover the details of the flow field.…”

An interceptor is an appendage widely used for high-speed planing boats to reduce resistance and modify hull attitude by the lift force-induced, but the relationship between the induced lift force and the factors affecting it are still not clear, especially for the vessels other than the planing hull. In this paper, a model test of a series of models is performed to investigate the lift force induced by an interceptor and the influence of the affecting factors systematically. The lift forces induced by the interceptor are tested in the conditions of different velocities, interceptor heights, angles, and drafts in the towing tank. The effects of each factor and the coupled effects are analyzed. It is found by the experimental results that the lift coefficient of the induce lift force in the present investigation is approximately proportional to the square of the non-dimensional velocity and interceptor height, but the effect of the interceptor height is of a limited extent. The influence of angle and draft on the lift force induced by the interceptor cannot be ignored in the present study. The induced lift force is decreased when the angle of the plate is reduced and is enhanced when the draft is increased.
