Abstract. A Multi-Disciplinary Analysis and Optimisation (MDAO) system for the evaluation and optimisation of the performance of a High-Speed Civil Transport aircraft has been developed at ONERA within the context of the CISAP project. This paper first describes the MDO system implemented at ONERA. This MDO system is constructed by coupling a Multi-Disciplinary Analysis (MDA) process, developed in the present research project, with different optimisation algorithms including a gradient-based optimiser and a Genetic Algorithm (GA). The MDA process embeds the different disciplines modules and schedules and monitors their execution. It is capable of evaluating the global aircraft performance for a specified mission.
