Research on Co-simulation Strategy and Model Exchange Technology for Aero-engine Multi-Disciplinary Simulation*

Aero-engine is a typical multidisciplinary complex system. The design index of aero-engine gradually approaches its theoretical limit. The single component simulation is difficult to meet the design requirements. It is inevitable to carry out 3D multi-physical field coupling, multi-system co-simulation and mixed-dimensional simulation for complex core engine. Although the academic community carry out research work in the above fields, it still focuses on a certain point of technology orientation. The complex engineering problem is still unresolved. Therefore, it is necessary to propose the multidisciplinary simulation scenarios in detail from the research and design mode. In this paper, the transformation technology of multidisciplinary simulation model and the co-simulation control strategy of different solver software are studied. And the co-simulation platform architecture is designed.
