高速双体船阻力性能与 K/L 及航速范围的选择

Resistance Property of High Speed Twin hull Ship and Determination of K/L and Ship Speed Limits

通过模型试验得出高速双体船两片体中心线间的间距与船长的比值（Ｋ／Ｌ）对阻力性能的影响与常规低速双体船不同的结论；并推测产生这种现象的原因；讨论了高速双体船尺度要素及航速选择的注意问题．

On the basis of model test,this paper gives the influence of K/L (ratio of the distance between two half hull centre lines over ship’s length) on the resistance property of high speed twin hull ship,and finds the influence is different from those of low speed twin hull ship.It deduces some possible reasons caused the differences.A brief disscussion on determination of principal dimensions and speed of high speed twin hull ship is also made.
