摘要

探讨压气机转子漏流涡与叶片气弹稳定性的相关性。将翼尖涡法(TVM)和集中翼尖涡法(CTVM)分别与预估叶片颤振的变形激盘法相结合

探讨了漏流涡与叶片气弹稳定性的相关性。计算结果表明

漏流涡对叶片气弹稳定性影响较大

大涡量的漏流涡能抑制叶片颤振发生。计算结果与实验一致。

Abstract

By using the Tip Vortex Method (TVM) and the Center Tip Vortex Method (CTVM) with the deforming disk method of flutter prediction respectively

the relationship between the tip leakage vortex and the blade aeroelastical stability has been studied.The results show that the tip leakage flow vortex has a great effect on the blade aeroelastical stability and large tip leakage vorticity may restrain blade flutter.The calculational results are consistent with the experimental data.
