航空发动机内部冰晶结冰研究综述

Review of Ice Crystal Icing in Aero-Engines

为深入理解航空发动机内部冰晶结冰现象,把握冰晶结冰过程的特征规律,建立科学有效的冰晶结冰防护手段,对近年来冰晶结冰文献资料进行了调研和总结。回顾了冰晶结冰现象的发现与证实的过程,重点阐述冰晶结冰与过冷水结冰的区别、冰晶结冰模拟试验及计算方法,并对冰晶结冰问题有待进一步研究的方向做了展望。

In order to deeply understand the ice crystal icing(ICI)phenomenon in aero-engines,grasp the characteristics of ICI process,and establish scientific and effective ICI protection means,literature and data on ICI in recent years were investigated and summarized.The discovery and confirmed processes of ICI were reviewed.The differences between ICI and supercooled water icing,simulation tests and computational methods of ICI were emphasized.At last,several directions for the further research on the ICI problem were proposed.
