一种航空发动机总体结构布局评价方法

An Evaluation Method for The Structure Layout of Aero Engines

总体结构布局设计是航空发动机方案设计阶段的重要环节,总体布局的好坏对航空发动机产品的研制全过程影响重大。其涉及知识面非常广且存在多学科耦合,很多影响因素难以量化,如何对总体布局进行评价并对多个待选方案按需择优选取的问题具有模糊性和复杂性。本文对基于层次分析法的航空发动机总体布局设计的评价进行探索,为更科学更有针对性的进行布局评价和方案选取提供新思路。

The structural layout design is an important part of the scheme design stage of the aero-engine,and the quality of the layout has a great impact on the whole process of the development of aero-engine products.It involves a wide range of knowledge and multidisciplinary coupling,many influencing factors are difficult to quantify,and how to evaluate the overall layout and select multiple options according to the needs is ambiguous and complex.This paper explores the evaluation of the layout design of aero-engines based on nalytic hierarchy process,which provides new ideas for more scientific and targeted layout evaluation and scheme selection.
