温度梯度对航空发动机转子热弯曲的影响分析

The Influence of Temperature Gradient on the Rotor Thermal Bending of one Type of Aeroengine

通过计算流体力学方法,分析了某型号发动机模化转子在不同的升温阶段、不同的环境温度以及不同的冷吹条件下转子的温度分布,并研究了不同温度梯度下转子变形的规律,为该型号发动机研制提供理论支撑。

By the method of computational fluid mechanics,the paper analyses the changes of temperature distribution under conditions of different heating time,temperature of environment and cold blowing rate for one type aero engine modeling rotor.And it studies the regulation of deformation with temperature gradient,which provides theoretical support for development of the engine.
