In order to reduce the environmental impact of aviation, one of the solutions is to develop more efficient aircraft. These gains can be achieved in different fields such as propulsion, aerodynamics or electrification of systems. This paper focuses on the sizing and optimization of BEITA, a short-medium range aircraft architecture available in the short term by 2025-2030. The aircraft is based on incremental technologies for propulsion, aerostructure and bleedless systems. Light-weight models are proposed for the different improvements, particularly for more electric systems. FAST-OAD, an open source framework for rapid overall aircraft design based on multidisciplinary design analysis and optimization, is used to size the new architecture and a specific life cycle assessment module is used to estimate the environmental impacts. BEITA allows a reduction in fuel consumption of 15% compared to the CeRAS reference aircraft. Optimizations of this architecture are achieved minimizing different cost functions. This study ends with a sizing on a shorter range based on specific payload-range diagrams. |
