概要

A Wing-In-Surface-Effect-Ship (WISES) runs at high speed in close proximity to the sea surface to utilize the high lift to drag ratio due to the surface effect. When they are affected by the disturbance, they'll possibly touch the sea surface. So it will be important for the safety of WISES to study about the motion of WISES under disturbances. The authors have constructed a computer simulation model of 6 free degree motions to evaluate the motion of WISES in any conditions of disturbance. The model expresses the nonlinear aerodynamics characteristics due to height, and Aerodynamics derivatives are functions of height. In the present report wind (gust) and wave are assumed as the disturbaces. In order to investigate the motions of WISES due to the disturbances, simulations with the newly proposed model are carried out in some conditions of disturbances. By the simulation results, it is clearly found that the lateral motion is also essential for WISES safety.
