以已有核心机为基础进行发动机系列发展的初步研究
A Preliminary Analysis of Developing Series of Engines Based on an Existing Core Engine
-
摘要: 在已有的核心机基础上可发展出一系列发动机。部件匹配的约束条件将限制设计循环参数的选择。为了进行定量分析,建立了一个性能仿真模型。以发展大涵道比涡扇发动机为例,说明了约束条件对设计循环参数的限制。初步分析给出了循环参数和总体性能间的关系。Abstract: A series of engines can be derived based on an existing core engine.Components matching constraints will restrict design cycle parameter selection.A performance simulation model was established for quantitative analysis.As an example,the development of a high bypass ratio turbofan engine was used to demonstrate how the constraints restrict design cycle parameters.Preliminary analysis shows the relationship between cycle parameters and engine performance.
