Abstract: According to the summary, analysis and reviews of the historical development and evolution of aircraft noise control technology, the goal, method, process, theoretical model and development trend of integrated aerodynamic as well as acoustic design of civil aero-engine are studied. Firstly, based on the analysis of aero-engine aerodynamic design process, the integrated aerodynamic and acoustic design method and process of aero-engine is presented. Then, the paper introduces aeroengine acoustic design in the three processes of “overall thermodynamic cycle design of engine”, “through-flow design of engine components” and “three-dimensional detailed design of engine components”, analyzes the development of aeroacoustic design theory and technology, and discusses the theory, model and method of aeroacoustic design of aeroengine in detail. Finally, the paper analyzes the main problems of aeroengine acoustic design theory and the future research focus as well as development direction. The aeroacoustic design method of the engine in different design stages is analyzed with a specific engine design example.
