Integration Aspects for Large Generators into Turbofan Engines for a Turbo-electric Propulsive Fuselage Concept
Paper i proceeding, 2019

The present paper discusses some aspects of integrating large generators into turbofan engines for a turbo-electric propulsive fuselage concept (PFC) pursued within the European Commission funded collaborative research project CENTRELINE (“ConcEpt validatioN sTudy foR fusElage wakefiLIng propulsioN intEgration”). In this proof-of-concept project a rear-mounted electric fuselage fan ingests part of the fuselage boundary layer. The fuselage fan is powered by power offtakes from two under-wing podded geared turbofan engines. The enabler to generate the electrical power needed to drive the wake filling aft fuselage fan is a sound integration of a large generator (5MW class) into the under-wing podded turbofan engines. Different integration concepts were compared in a down selection process leading to the most promising concept. For the selected concept the most concept-critical topics are discussed.
