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.
