| 摘 要： | 基于Eppler翼型设计方法提出一种新的抗空泡翼型剖面设计方法。新的设计方法利用预先给定的最大厚度和设计升力系数进行翼型剖面设计,并将厚度及拱度的分布与攻角的设置相结合,将所需的厚度与拱度分布转换为合理的攻角分布作为输入,以便用Eppler方法进行翼型剖面设计,并通过对攻角分布进行修改来调整空泡斗的位置。计算表明,所提出的方法对控制翼型剖面的厚度和拱度分布有效,利用该法设计的翼型剖面具有较好的空泡性能。

| Abstract: | A design method of new anti-cavitation airfoil profile based on Eppler design method was developed in this paper.This new design method was used for airfoil profile design with the specified thickness and lift coefficient.The relationships among camber distribution,thickness distribution and angle of attack were studied.An effective way which could control the position of cavitation bucket was also presented.The computation results demonstrate that the design method proposed is effective to control the thic... |
