초록

The running attitude of a planing hull is determined by the pressure distribution on the hull bottom, and it significantly affects hydrodynamic performance of the ship, i.e., resistance, maneuverability, and seakeeping ability. Therefore, it is essential to investigate pressure distribution on the hull bottom in order to improve hull design. In the present study, a novel pressure measurement system using tactile sensors was introduced for a planing hull. The test model was a 23 m-class planing hull with a hard chine. The pressure measurement showed that the pressure at the transom was lower than the atmospheric pressure, owing to flow separation at the transom.
