| 摘 要： | 本文通过艇底流态显示、艇体运动姿态及阻力测量，研究了滑行艇艇底喷气对流场、阻力等的影响规律。断阶稍前处喷气引起总阻力和浸湿面积的大幅减少，喷气所减少的阻力成分为摩擦阻力，喷气对剩余阻力的影响甚微。

| Abstract: | The effects air injection on the flow field and the resistance of stepped planing craft are investigated,through flow visualization technique and by measuring the motion and resistance of the model craft.The total resistance and wetted surface area of the model are reduced largely by injecting air just ahead of the step,air injection has a substantial effect on frictional resistance,but has no obvious effect on residual resistance. |

| Keywords: | stepped planing craft resistance air cavity wetted surface area |
