| 摘 要： | 本文用螺桨-吊舱相关分析法对桨扇进行设计和分析。用曲线升力线代表桨叶,并且考虑吊舱存在的影响;方法采用尾迹位于流面上的假定。对叶尖段进行跨音修正,对根部应用叶栅最佳损失攻角加以考虑。设计和分析的结果与文献〔2〕的计算和试验结果作部分比较,证明了本法的合理性和有效性,可以应用于桨扇的初步设计和性能分析中。

| Abstract: | A propeller-nacelle interaction analysis has been developed in this paper as a kind of lifting line analysis. It represents the blades by curved lifting lines, taking into Consideration the blade sweep and the effect of the nacelle on the propfan flowfield. The wake model assumes that the vortex filaments occur along stream surfaces. Some corrections have been made to transonic portion of the blade and large solidity cascade portion at hub. Comparison of the results of the design and analysis with those given in references show the method is feasible and effective, Aspects of its improvement are also discussed. |
