【摘要】 交通部上海船舶运输科学研究所船模试验池完成了一组长江双桨客货船定序系列。对内河船也可参考使用。系列的船型参数范围如下:C_B=0.53～0.64;L/B=4.6～7.0;B/T=3.6～6.0。系列提供了一组船型和阻力图谱,以及当设计船舶的水线面系数不同于系列值时对型值和阻力的修正方法。摩擦阻力按1957年 ITTC 相关线计算。文中还给出了当使用 Prandtl-Sohlichting 摩擦公式时的摩擦修正。限于篇幅,本文只给出五张阻力图谱。与 Taylor 系列以及一些优良船舶比较,本系列的阻力性能是良好的。更多还原

【Abstract】 In recent years a methodical series of the Yangtze River liner with twinscrews has been completed in the ship model basin of Shanghai Ship andShipping Research Institute of the Ministry of Communications.It may bealso used for the inland waterway vessels.The form parameters of the seriesare as follows:C_B=0.52～0.64;L/B=4.6～7.0;B/T=3.6～6.0.This paper provides a set of charts of the hull effects and the resistance,and a correction method for the offsets and resistance,when the waterline areacoefficient of the designed ship is different from that of the series.The fric-tional resistance is calculated according to 1957 ITTC correlation line.A frictio-nal correction is given when the Prandtl-Schlichting frictional formula isused.Compared with the Taylor series and some fine shipform,it proves thatthe resistance characteristic of this series is reasonably good.更多还原
