Abstract:

The high-quality development of China’s social economy and industrial system in the new era presents higher requirements for the development of aero-engines. It is urgent to improve the agile Research and Development (R&D) capability of products, strengthen the foundation of independent R&D, and improve customer satisfaction by means of systematization of digital engineering. The present situation and development trend of digital engineering in foreign countries were analyzed. Based on the foundation of digital engineering construction in aero-engine industry of China, the general technical framework of digital engineering for aero-engines was proposed. The application scenarios of digital engineering in the aero-engine life cycle were preliminarily defined. The key technologies of aero-engine digital engineering construction were exploratively identified and analyzed. Finally, construction and implementation suggestions were proposed, such as gradually implementing pilot projects, constructing a digital ecosystem and culture, making overall planning for calculation and supporting, and strengthening simulation reliability.

Key words: aero-engine, digital engineering, digital system model, digital thread, digital twin
