摘要
本文通过试验 ,研究了不同喷气方式对断阶滑行艇模型阻力的影响 ,取得了总阻力减少 2 5 %的效果 ,并得出了以下结论 :( 1)孔喷的减阻效果明显优于缝喷 ;单侧喷气的减阻效果略差于双侧喷气。 ( 2 )沿折角线垂向下弯式的防溅条的阻力性能优于沿折角线水平式的防溅条 ,前者的单位排水量阻力比后者的略小 3 %～4%
The effects of different air injection techniques on resistance of stepped planing boats are investigated experimentally in this paper. The total resistance is reduced by 25%. Pore injection is more effective than slot injection on resistance reduction. The more reduction of resistance is achieved by double side air injection than by single side air injection to a least extent. The R t/W of spray strip 2 is less than that of spray strip 1 by 3%～4%.
