Abstract
Digital twin is a generic term used across disciplines to mean a digital copy of a physical entity. Facilitated by the new generation of information technology, the digital twin has drawn more and more attention from both academia and industry. Especially, as predicted in many studies, this technique has great potential to bring innovative and revolutionary changes for aerospace. This chapter gives a general introduction of digital twin. Furthermore, its application for the maintenance, repair, and overhaul of aircraft is outlined. In this chapter, first of all, the concept of digital twin is introduced, including its generation, development, and general components. Then, the maintenance process for aircraft as well as the existing issues is described. After that, the digital twin with the application of aircraft maintenance is elaborated from the perspectives of concept, system architecture, and system implementation. Subsequently, three cases are presented to illustrate how this digital twin works in the health status evaluation, future health status prediction, and maintenance activity management. At last, the summary of this chapter is made, along with a review about the challenges faced for implementing digital twin technology in aerospace.
