Abstract:

Aeronautical fatigue and structural integrity are critical throughout the entire life cycle of an aircraft, ensuring flight safety. Digital engineering, as an integrated digital method, offers more efficient, reliable, and economical solutions for aircraft structural design, verification, operation and maintenance. It represents a significant future direction for aircraft structural safety design and sustainability. Central to digital engineering is the emphasis on models, with digital twin playing a pivotal role in integrating various models and measured data to achieve accurate assessments and maintenance of fatigue and structural integrity. This paper, informed by recent research findings presented at the 31st Symposium of International Committee on Aeronautical Fatigue (ICAF), reviews the progress in key technologies related to digital engineering and digital twins, alongside their applications in aircraft structural design, verification, operation and maintenance. The paper also offers perspectives on future developments in these technologies to encourage further advancement and application of digital engineering and digital twin concepts.

Key words: digital engineering, digital twin, aircraft structure, fatigue and structural integrity, structural simulation
