Modeling, Simulation and Performance Comparison of Variable Cycle Engine Based on Object-Oriented

In order to overcome the shortcomings of the traditional process-oriented aero-engine simulation software, an object-oriented simulation software platform was developed to model the specific components of the variable cycle engine, and the configuration of the variable cycle engine could be built freely by users. Three common variable cycle engines are set up in this paper. Considering their different structures, given the same pressure ratio and bypass ratio and other parameters, the potential of the three variable cycle engines cannot be brought into play. In this paper, intelligent optimization algorithm is adopted to adjust parameter optimization space for cycle parameters and non-design point components given the same design point. The performance of the proposed engine is optimized under the conditions of ground take-off point and high altitude cruising point. The optimization results show that the comprehensive performance of ACE is better than that of FLADE VCE and CDFS VCE.
