Review: Engine-level Performance Simulation of Aeroengine and Gas Turbines

Engine-level performance simulation is an integral aspect of aeroengine and gas turbine simulation, and plays a crucial role throughout the entire life cycle of design, manufacturing, and operation. This paper presents a comprehensive analysis of the development process of aeroengine and gas turbine performance simulation in each historical stage, building upon the accomplishments made over the past 70 years. The research status of physical mechanism performance simulation, primarily represented by the component-level model, was examined from various perspectives including basic methods, model refinement, solution algorithms, and correction methods. Further? more, the application of artificial intelligence algorithms, such as the artificial neural network, support vector machines, and deep learning, in engine-level performance simulation, was discussed. The paper also provided an overview of the fundamental methods and key achieve? ments of on-board models, mechanism-data hybrid models, and multi-dimensional models. Finally, based on current research findings and technological development trends, it is believed that the engine-level performance simulation of aircraft engines and gas turbines should de? velop towards a more refined physical mechanism model, deeper artificial intelligence technology, and more standardized application model construction.
