This paper presents an aircraft configuration trade space exploration for NASA’s SUbsonicSingle Aft eNgine (SUSAN) Electrofan, which is a 180 passenger regional class transport aircraftthat utilizes electrified aircraft propulsion and advanced propulsion airframe integrationtechnologies to enable reduced fuel consumption and emissions. At its core is a hydrocarbonfuel-consuming aft fuselage propulsor that produces 35% of the total thrust while generatingpower to drive wing-mounted electric propulsors, which produce the remaining 65% thrust.This power is extracted from the aft fuselage propulsor via a set of generators and is managedwith the help of a rechargeable battery, classifying the propulsion system as hybrid electric.Investigated in this work are different aft fuselage propulsor concepts, several wing propulsorconfigurations, and different types of stability and control strategies that can be accommodatedby this hybrid electric system architecture, with an emphasis on aircraft performance. Resultsobtained using a low-order multidisciplinary design and analysis framework demonstrate thateven with a subset of the advanced technologies that are being considered for the SUSANElectrofan, significant improvements to fuel efficiency can be achieved.
