Technology readiness assessment and performance forecast on a 19 seats E-STOL EIS 2032

Abstract

The European Flightpath 2050 connectivity goal, to enable European people to reach any desired destination, door to door, in 4 hours, increases the interest in Small Air Transportation (SAT), to enhance global connectivity. The connectivity goal should come alongside with environmental target: FlightPath 2050 aims to reduce by 75% C02 emissions and by 90% NOx emissions. Within the EU Clean Sky 2 framework, a future affordable and green commuter belonging to EASA CS 23 has been designed, collecting all the novel technologies developed in the CleanSky 2 frame [1]. This work presents a further step on the 19-seater development: a technology readiness and assessment to electrify the short take-off and landing (STOL) aircraft is presented, considering the expected entry into service (EIS) in 2032, rationalizing the design choices considered as most suitable to obtain a hybrid electric E-STOL and the consequent gains in terms of emission reduction on a typical mission range.
