Parallel hybrid-electric propulsion systems have been researched and are under development for retrofitting regional turboprop airliners to reduce fuel/energy consumption, carbon emissions, and heat losses compared to current gas turbine propulsion systems. Performance benefits and capabilities of such electrified aircraft propulsion concepts are highly sensitive to vehicle, powertrain, and energy storage system sizing, where the current regional turboprop market is composed of airliners of varying capacity. The objective of this study is to examine how performance benefits and design trade-offs scale for hybrid-electric regional turboprop transport across varying seat classes and operational ranges.
