Requirements engineering for radical innovation – Application to helicopter engine fuel system
Résumé
Requirements engineering (RE) is a major step of the System Engineering Process. Thus, when considering radical innovation, this step appears to be crucial to generate original designs. The paper is built around a case study of the helicopter engine fuel system at Safran Helicopter Engines, a major helicopter engines manufacturer. Its fuel system architecture has been incrementally evolving for more than thirty years. In order to anticipate the future expectations of stakeholders, it seems necessary to deeply rethink the fuel system through radical innovation. In this communication, a literature-based methodology for RE applied to radical innovation is proposed. This methodology has been deployed in an industrial case of a critical embedded power system and provided valuable feedback for adapting and improving the proposed methodology.
