航空发动机压气机转子重量预估方法研究

An Investigation on Prediction Methods of Aeroengine Compressor Rotor Weight

在航空发动机结构方案设计阶段,要从众多设计方案中选出一个既合理、又经济,既满足性能要求、又具有较轻重量的设计方案,需要对不同设计方案进行重量预估。本文针对压气机转子,提出了一种预估其重量的方法,并进行了实例计算,取得了较满意的结果。

In the initial design phase of aeroengine, it is important to select an economic and reasonable design from many schemes to meet the performance requirements and reduce engine weight. It needs to predict the engine weight of different designs. In this paper, a method to predict compressor rotor weight has been described with a calculation example. The results are quite acceptable.
