With the rapid advancement of digital technology, digital twin (DT) has become a cornerstone of digital engineering in equipment development. This paper analyzes the conceptual framework and current state of DT in aviation, focusing on aircraft system integration. We propose a technical roadmap with key methodologies like multi-disciplinary mechanism coupling, high-fidelity model integration, and virtual-real interaction, supported by mechanism-data fusion modeling. A novel multi-element framework for aircraft systems is introduced to address multi-level, multi-disciplinary development needs. Through typical scenarios, we demonstrate DT's benefits in improving design efficiency, testing safety, and operational economy. Future directions for digital-intelligent convergence are also outlined.

摘要

With the rapid advancement of digital technology, digital twin (DT) has become a cornerstone of digital engineering in equipment development. This paper analyzes the conceptual framework and current state of DT in aviation, focusing on aircraft system integration. We propose a technical roadmap with key methodologies like multi-disciplinary mechanism coupling, high-fidelity model integration, and virtual-real interaction, supported by mechanism-data fusion modeling. A novel multi-element framework for aircraft systems is introduced to address multi-level, multi-disciplinary development needs. Through typical scenarios, we demonstrate DT's benefits in improving design efficiency, testing safety, and operational economy. Future directions for digital-intelligent convergence are also outlined.
