A Robust Digital Twin Framework for Coaxial Helicopters: Development, Validation, and Practical Implications

The advancement of Digital Twin (DT) technology, which serves as a digital representation of a physical object, system, or process, enables the simulation of real-world scenarios and enhances decision-making processes. In the aerospace industry, where product development and aircraft operation have substantial costs, using a validated aircraft model offers a cost-effective and safe approach for analyzing diverse attributes. This paper presents the development of a DT for coaxial rotorcraft. The model is demonstrated and validated through a case study of the CoAX600 helicopter and its flight data. The study highlights the importance of validation in ensuring the DT's accuracy and reliability before its practical application in flight scenarios.
