The Turbo-electric Distributed Propulsion (TeDP) is a novel concept of hybrid aircraft propulsion for commercial aircraft. E-Thrust employs electrically powered fans dedicated to thrust generation which are distributed in clusters along the wingspan, together with one gas power unit providing the electrical power for the fans and for the re-charging of the energy storage system using superconductors. Furthermore, aft-positioned propulsive compartment enables the advantages of Boundary Layer Ingestion (BLI) phenomenon. The paper deals with the preliminary sizing of Li-air battery pack for the TeDP considered. A comparison between Jet A-1, liquid natural gas (LNG) and liquid hydrogen (LH2) fuels is performed with an interest on the energy storage system. Also, the impact of different fuels on some of the aircraft’s subsystems is discussed. Finally, the results are discussed, and the future activities are suggested.

Abstract
The Turbo-electric Distributed Propulsion (TeDP) is a novel concept of hybrid aircraft propulsion for commercial aircraft. E-Thrust employs electrically powered fans dedicated to thrust generation which are distributed in clusters along the wingspan, together with one gas power unit providing the electrical power for the fans and for the re-charging of the energy storage system using superconductors. Furthermore, aft-positioned propulsive compartment enables the advantages of Boundary Layer Ingestion (BLI) phenomenon. The paper deals with the preliminary sizing of Li-air battery pack for the TeDP considered. A comparison between Jet A-1, liquid natural gas (LNG) and liquid hydrogen (LH2) fuels is performed with an interest on the energy storage system. Also, the impact of different fuels on some of the aircraft’s subsystems is discussed. Finally, the results are discussed, and the future activities are suggested.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
