摘要:

航空发动机非定常流固热声耦合问题涉及发动机性能、适航性和安全性等多个方面,是高性能航空发动机自主研制中不可回避的重要难题。转子叶片非同步振动是航空发动机压气机中出现的一类新的气动弹性问题,涉及多学科交叉。随着压气机气动负荷不断提高和叶片阻尼的下降,新研制的高性能压气机暴露出非同步振动问题,导致叶片振动应力超限,其引发的叶片断裂故障也屡见不鲜,但对其产生机制和控制方法尚未完全摸清。梳理和总结了国内外轴流压气机叶片非同步振动现象和特征,对转子叶片非同步振动的产生机制、影响因素、抑制方法的研究进展进行了回顾,旨在扩展压气机内不稳定流动诱发叶片非同步振动方面的基础理论认知,为先进航空发动机自主设计研制和故障分析诊断提供技术储备,并对该领域未来的发展进行了展望。

Abstract:

The unsteady fluid-solid-thermal-acoustic coupling problem of aeroengines involves multiple aspects such as engine performance, airworthiness, and safety, which are unavoidable in the independent development of high performance aeroengines. Non-synchronous vibration of compressor rotor blades is a new type of aeroelasticity problem, involving multidisciplinary intersection. With the increase of aerodynamic load and decrease of damping, new high performance compressors have encountered the non-synchronous vibration problem, leading to excessive vibration stress of the rotor blade, and the blade fracture failure caused by it is also common. However, its mechanism and control method have not been fully understood. The phenomena and characteristics of non-synchronous vibration of axial compressor blades are reviewed and summarized. Then, the research progress of the generation mechanism, influence factors and suppression methods of non-synchronous vibration is reviewed, aiming to expand the theoretical understanding of the non-synchronous vibration induced by unstable flow, as well as to improve the independent design and troubleshooting abilities of advanced aeroengines. Finally, the future development of this field is prospected.

Key words: axial compressor, non-synchronous vibration of rotor blade, flow instabilities, aeroelasticity, vibration suppression
