The call for proposals under the European Defence Fund is focused on developing an advanced digital twin (DT) framework specifically tailored for complex aerial systems. This initiative is designed to integrate multidisciplinary simulation capabilities that encompass aerodynamics, structural analysis, flight control systems, embedded software, and other key engineering domains. The overarching objective is to create a System of Systems (SoS) DT, a validated virtual replica of physical assets and processes, that provides a holistic, real-time view of the entire system behavior and performance. By fusing together multiple DTs from individual systems, subsystems, and components, the framework will enable simulation, performance optimization, and informed decision-making throughout the lifecycle of military aerial systems.

The project emphasizes a modular approach, where individual DT modules are developed progressively and then integrated into a larger digital rig. This structure facilitates a gradual scale-up from subsystem-level modelling to full aerial system simulations, thereby de-risking the development process. The call also aims to address the interoperability challenges that arise due to the diversity of data formats, simulation tools, and modelling techniques. To overcome these challenges, proposals are expected to improve standardizations, develop middleware solutions, and implement data catalogues that ensure seamless data exchange and consistency across multiple platforms and nations.

A key aspect of the call is the exploration of both technical and non-technical benefits of DT technology. On the technical side, the project will focus on high-fidelity simulations, the integration of sensor data, cybersecurity measures, and the establishment of a federated architecture for real-time data transfer and analysis. This involves the development of a communications backbone system capable of managing high-frequency data flows, cloud-based storage solutions, and AI-driven analytics for predictive maintenance and operational supervision. On the non-technical front, the proposals should consider the DT’s potential for managing cost overruns, progress reporting, and enhancing coordination among multinational capabilities through a common model database.

In addition to technical studies, the call mandates the design of a comprehensive reference architecture that supports modularity, scalability, and standardization. This architecture must demonstrate the capability to work across the entire systems development lifecycle – from initial concept design and simulation through to certification and operational deployment. Proposals will include a demonstrator that validates the performance and integration of the digital twin system using real operational data from military assets. The expected outcomes include enhanced fleet reliability, improved maintenance planning, accelerated product development, and increased operational safety.

Overall, this funding call seeks to revolutionize military aerial system design by leveraging digital twin technologies to provide unprecedented insight into system performance, streamline the certification process, and ultimately contribute to operational superiority and lifecycle efficiency.
