本文提供了一种内河浅水型高速艇艇型.针对该型线又进行了不同水深的阻力模型拖曳试验,并根据试验结果讨论了高速艇的浅水效应.结果表明,该艇的水动力性能优于常规的高速艇艇型.配合本文提出的带有侧进水口及底进水口的双进水口喷水推进系统的概念设计,该高速艇可在深水中高速航行、在浅水中安全航行,有效最小水深可和该艇的静态吃水相当.

Hull form of a high-speed shallow-water craft used in fresh water is presented in this paper. Model tests for this hull lines are conducted at different water depth in towing tank, and the effect of shallow water on craft performance is investigated.Test resahs show that powering performance of this craft is superior to other representative planning boat, no matter in deep or shallow water. Concept of double-inlet water-jet system is designed with one inlet in side and the other in bottom.This craft,combined with the double-inlet water-jet system, can run in deep water with high speed and safely run in shallow water. The critical water depth can almost be the same as the draft of this craft.
