变循环发动机总体结构和模式转换机构研究

根据1种涡扇发动机的总体结构设计方案,围绕变循环特征的适应性进行了改进设计,给出了变循环发动机的总体结构初步方案,设计了模式转换原理及其结构实现方案;以其可调面积涵道引射器的设计为例,进行了模式转换机构运动仿真及其关键件的有限元分析,从机构运动和强度分析方面确定了该方案的可行性.

Investigation of General Structure and Mode Transition Mechanism of Variable Cycle Engine

The improved design was performed around the adaptability of variable cycle feature based on the general structur design concept of a turbofan and the preliminary concept of the variable cycle engine general structure was given and the mode transition principle and structural enabling concept were designed.Taking design of the variable area bypass ejector as example,the motion simulation and the finite element analysis of key components were performed and the feasibility of concept was determined from mecha...
