Future advanced engines face challenges such as complex matching mechanisms, and a high degree of coupling between thermodynamic cycle parameters, component performance, and flow path geometry. Additionally, the conceptual design phase offer suffers from a lack of input parameters. To address these issues, a general-purpose coupled simulation architecture and process were established. Based on empirical correlations and component coupling diagrams, a coupled design method for thermodynamic cycle parameters and flow path geometric parameters was developed. This method enabled the prediction of component efficiency levels under different thermodynamic cycle parameters and yielded the inlet and outlet dimensions of key impeller components. Using the proposed method, simulation validations were carried out on three engine models: a mixed-flow turbofan engine, an adaptive variable-cycle engine, and a “dual variable” cycle engine. The results showed that the estimated flow path geometric parameters of rotating components obtained by this method had errors within 10% compared with actual design values or values reported in the literature, achieving a level of prediction accuracy for engine flow path dimensions comparable with that of NASA. This approach effectively shortens the iteration cycle in the scheme design phase, reduces the risk of major design changes in subsequent stages, and provides valuable reference for detailed engine design.
