Abstract
AbstractEnhanced complexity of modern systems often brings challenges in achieving performance, cost and time targets during development. Aero gas turbine engines are highly complex systems involving several modules and subsystems. Full Authority Digital Electronic Controller (FADEC) of aero engine is a very complex subsystem by itself, encompassing hardware and software to control the engine during all phases of operation. The current paper outlines an approach for system‐level design of FADEC using model‐based systems engineering (MBSE). FADEC is described comprehensively and consistently using SysML language. This includes defining the requirements of FADEC, importing them into SysML model and analysing these requirements, proposing multiple operations including the flow of control and data to fulfil these requirements, proposing a high‐level system architecture, modelling the interaction between subsystems, and verifying system performance through simulation. This model is expected to help individual design teams in development of the FADEC meeting the project goals.
