Assessment of (hybrid)-electric drive-train architectures for future aircraft applications

Abstract Future regional aircraft and propulsion systems will have to address both a growing market stricter environmental constraints. Besides the increase of component efficiencies, technological transformation from conventional (hybrid)-electric represents paradigm shift with great potential for aviation industry. In this context, economic, market-relevant as well boundary conditions electrical mechanical components are developed in paper reference based on current research results different institutions. The performance analysis turboprop is compared evaluated serial-hybrid fully-electric configuration (both battery-electric), status today ~2035, an example, whereby presented process can also be applied other hybrid configurations too. An energy-optimised operating concept derived regard minimum resulting system weight. help define necessary future subsystem investigations identify key items, especially field battery.
