Once again, the recent trend of super high-speed ships is to use a Power-Augmented Ram Wing In Surface Effect Ship(=PAR-WISES). APAR-WISES is a wing in free-surface effect, whose lift is enhanced by using the air flow of a thruster, which is placed upstream of the wing, so as to create a high pressure region under the wing. The PAR effects enable the vehicle to take off and land at lower speed and the structual weight and engine power can be reduced compared with conventional WISES.<BR>In order to understand the mechanism of PAR effects, measurements of pressure distribution on the lower surface of the wing and the ground, flow visualization for a low aspect ratio wing with end plates were performed in the wind tunnel at the Ship Research Institute. Aerodynamic characteristics and interactions among the wing, ground and thruster are discussed.
