Abstract:The philosophy for ensuring airframe safety has experienced the evolution from static strength, safety life, damage tolerance and durability, individual aircraft tracking, with a trend towards the airframe digital twin in the future. The airframe twin is a multidisciplinary, multi-physical, multi-scale, multi-fidelity, and multi-uncertainty virtual simulation system, which is driven by the digital thread. It uses multi-source data such as online sensor monitoring, offline ground inspection and aircraft operation history to reflect and predict the behavior and performance of the corresponding airframe physical entity within the entire life. It is expected to reform the existing paradigm of airframe usage and maintenance. Focusing on fatigue life management, five key modeling and simulation technologies are proposed in this study, which are (a) acquisition of load and damage data, (b) multi-scale mechanical modeling of airframes, (c) high-performance simulation of damage development, (d) efficient digital twin construction based on Reduced Order Modeling(ROM), (e)Remaining Useful Life(RUL) assessment considering multi-source uncertainty and heterogeneous data. This article discusses the state-of-the art of the proposed five key technologies as well as future research directions, providing references for the systematic study and engineering applications of the airframe digital twin.
