Preliminary Study on OBS Electrification Efficiency for Advanced Supersonic Business and Medium Jet with Unified Engines

The present paper would investigate the effect of on-board systems masses and power required on propulsion system and aircraft mission performance of two reference supersonic aircraft. The on-board systems are even more investigated since their importance in engine and aircraft performance optimization and their effect can be only quantified through a multidisciplinary design. Moreover, with the introduction of more and all electric concepts for on-board systems, more flexibility in their design is now possible considering different architectures. In particular, the analysis involves a supersonic business jet and a supersonic medium jet with different performance, passengers number and propulsion system. The analysis shows different behaviours on the propulsion system parameters with power offtakes and systems mass variations for the two aircraft. The results are interesting for future systems architecture selection and to understand the effect of their integration to the propulsion system.
