核心机派生涡扇发动机部件及整机匹配

以核心机与低压系统的部件及整机气动热力匹配关系为理论依据,在全面考虑低压压缩系统与核心机压气机的匹配约束关系、核心机涡轮工作状态相应变化以及派生发动机内外涵整机匹配的多因素下,建立了核心机派生涡扇发动机部件及整机气动热力循环匹配算法模型.应用该模型,进行了核心机派生涡扇发动机循环参数及性能趋势分析,计算结果表明高低压和整机匹配约束直接影响核心机派生涡扇发动机循环参数和整机性能,为核心机派生系列化涡扇发动机工程实践应用中所涉及的部件/整机参数匹配及性能预估提供分析和设计参考. 

Components and engine matching of core-derived turbofan

The gas turbine core-engine derivative model for turbofan serialization,which focused on thermo-cycle approach,was established based on components and engine matching between core-engine and low-pressure system.The model took into account high-low system interaction,core turbine operation and inner-outer duct compatibility comprehensively,and then it was utilized to analyze derived turbofans' cycle and performance.The results show that the coupled low-high systems' constraints influence turbofan's performance and cycle parameters,providing engineering reference and design criteria for core-derived turbofan's matching and simulation.
