Coordination of multidisciplinary teams is often a challenge when facing the design and development of complex systems subjected to strict product policies such as the standards applicable in the aeronautics industry.

Model-based systems engineering, and more generally, model-driven approaches to design and develop such systems offer alternatives to facilitate the work of the main stakeholders involved in the process. In particular, the paradigms of centralized source of information, enhanced traceability or automated analysis speed-up significantly the design and verification tasks and reduce the sources of errors; which results in an overall gain of quality in the engineering processes.

In this talk we will showcase the implementation of a model-driven approach to the design and development of an electromechanical actuator conceived to control the aerodynamic surfaces of a conventional aircraft. Our industrial partner is involved in a transformation process towards the digitalization of their engineering activities and is interested in particular in using MBSE as a way to foster collaboration between teams and ensure consistency across different engineering tasks.

Our work started with an analysis of different MBSE tools, evaluating the suitability of such tools to meet a set of criteria considered relevant to support efficiently the process, not only at systems engineering level, but also coupling with other engineering disciplines that will interact with the model. For different reasons that will be detailed in the webinar Capella was selected as the reference platform for this activity.

Using Capella, the stakeholder needs for the electromechanical actuator have been analyzed and developed across the system, logical and physical architectures. In the talk, the main features of the system will be described, emphasizing the specificities of the model that allow the coordination and sharing of information between teams (mainly electronics, simulation and RAMS).
