摘要
基于涡扇发动机的结构平台,围绕变循环概念,分析了变循环发动机的原理与结构。为了满足发动机部件的工作极限和适应宽广的飞行包线,采用分段控制方式,制定了变循环发动机的调节计划。对亚声速巡航和超声速巡航两个典型工况的循环模式转换的过程进行了数字仿真,设计并验证了既能满足发动机在转换过程中不发生喘振和堵塞,又能使转换过程稳定快速完成的调节计划。
Based on the configuration of turbofan engine and combining the concept of variable cycle engines,the collectivity configuration of variable cycle engine is analyzed.The adjustment plan of engine is designed to some subsections,for the sake of satisfying the operating limit of engine components and adapting wide flight envelope.On the operating mode of subsonic speed and supersonic speed,digital simulation is carried out pointing at the conversion of cycle modes,and the adjustment plan is checked since the engine doesn＇t surge and block,also the conversion of cycle modes is completed quickly.
