| 摘要： | Mathematical models developed for air-cushion-supported vehicles generally approximate the air pressure as being uniformly distributed within the cushion of the vehicle and assume that the pressure has no effect on the encountered wave field. The validity of these approximations is examined experimentally by measuring the spatial and temporal distribution of the air pressure In and wave elevation under the cushion of a high length-to-beam ratio surface effect ship model which is free to heave and pitch in irregular head waves. It is observed that the pressure is distributed nonuniformly in the cushion and the wave height distribution under the cushion appears to be modified from the encountered wave field primarily by the wave making effect of the bow and stern motion. |
