AI Technical Summary
In existing aero-engine performance simulation methods, the coupling relationships between components and between components and the whole engine are weak, resulting in insufficient performance prediction accuracy and making it difficult to meet the high-precision simulation requirements of modern aero-engines.
An integrated simulation platform using a whole-machine 0D model and a dual-rotor turbine 3D integrated model is used to perform mixed-dimensional simulation through aerodynamic coupling, which enhances the aerodynamic coupling between components and between components and the whole machine. By adjusting the performance parameters between the whole-machine 0D model and the dual-rotor turbine 3D integrated model, a refined description of component characteristics can be achieved.
It improves the accuracy of predicting component and overall engine performance, reduces the number of design and testing iterations, lowers R&D costs and risks, and enhances the development capability of aero-engines.
