摘要：
The matching of the double bypass engine compression system was investigated to reveal the operating mechanism of the multi-connected compression system of the variable cycle engine. Three-dimensional numerical simulation showed that there was a strong coupling between the compression components, the bypass ducts, and the bypass regulation mechanisms. A well-organized bypass flow was a key for the variable cycle engine to exhibit its aerodynamic advantage. The adjustment of the bypass regulation mechanism not only changed the flow state of the bypass but also influenced the matching state of the compression components, hence the mode transition required for the cooperation of all components. © 2022 BUAA Press.
