摘要
本文根据螺旋桨的升力线理论,分析了螺旋桨叶梢产生梢涡的机理,通过在叶梢处的截面上安装一个与螺旋桨同轴旋转面相切的弧面封板所进行的螺旋桨敞水试验,来验证叶梢安装叶片可使叶梢不产生旋涡,减少叶梢处能量损失,得出了初步的结论。
According to lifting-line theory, this essay analyses the mechanism about how the propeller blade tip can produce whirlpool. Through the open water test by installing one cambered closing plate which is tangent to a rotating surface with the propeller coaxially, the essay proves that whirlpool will not be produced by installing blade on the tip and meanwhile reducing the expense of energy on the tip, and the essay has drawn the preliminary conclu- slon.
