圆舭艇系列试验研究

SYSTEMATIC TESTS WITH ROUND BILGE DISPLACEMENT CRAFT

本文提供了长宽比L/B=3.6～6.0的圆舭艇模型在Froude数Fr=0.25～0.85范围内的阻力试验结果。文中还介绍了圆舭艇线型的确定方法。由于引用了“相当艇型”的概念。显著减少了系列试验的工作量。为便于设计部门使用,给出了综合图谱,可用于圆舭艇线型的方案设计和功率预估。

This paper presents resistance test results for round bilge displace- ment craft model series of length-beam ratio L/B =3.6~6.0 in the ra- nge of Froude number Fr=0.25~0.85. The constructive method of rou- nd bilge displacement craft hull lines is also illustrated. The number of testing model may be reduced obviously, since the concept of 'Equiva- lent Ship Form' is introduced. The synthetic charts have been made for the lines drawing and the power prediction in preliminary design stage.
