Power plant pre-design exploration for a turbo-electric propulsive fuselage concept

With intent to advance the exploration of a promising concept for synergistic wake filling propulsion system integration, the power plant characteristics associated with a Propulsive Fuselage Concept are investigated in this paper. In the targeted configuration a turbo electric power train is envisioned comprising an electrically driven, boundary layer ingesting fuselage propulsor in conjunction with two underwing podded Geared Turbofan engines providing electrical power offtake. Addressing the extraction of significant levels of power offtakes, upon the discussion of the modelling approach and simulation setup, a variety of parametric studies are presented with emphasis placed on discussing the operational space available for variations of power offtake as well as the effects on the design characteristics. In addition, exploratory studies on the design and performance characteristics of the fuselage propulsor are presented.
