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。
To study the correlation between compressor rotor leakage vortex and blade gas bomb stability. The correlation between the leakage vortex and the stability of the blade is discussed by combining the tip-vortex method (TVM) and the concentrating wing tip vortex method (CTVM) with the predicted disk flutter method. The calculated results show that the leakage vortex has a great influence on the stability of the blade. The large eddy leakage vortex can suppress the flutter of the blade. The calculation results are consistent with the experiment.
