摘要
通过对高速艇艇底不同位置加设纵向防逸条,来控制气泡沿船体横向的逸出,增大艇底气泡的体积浓度,提高气泡船的减阻效果。考虑船体横剖面形状对气泡逸出的影响,特别是纵剖线形状的影响,又对优化后的新船型进行了气泡减阻计算。通过对计算结果的比较分析,寻求控制气泡逃逸的最佳技术措施。
In order to improve the drag reduction effect of air cavity craft,this paper uses longitudinal controlling air bubbles to escape bars which are fixed on the different sites of high-speed craft＇s bottom to avoid air bubbles escaping from both sides of the ship and increase the volume concentration of air bubbles.Considering the influence of the cross-sections and the shape of sheer-profile on air bubbles escaping,the numerical calculation about air bubbles is used by the optimized ship form.This paper compares the different results and tries to find the best technical measures of controlling the air bubbles to escape and then improving the drag reduction rate.
