Digitalization is of growing importance for industries and research institutions as it simplifies
and accelerates product development. By that it also offers the ability to reduce risks and …

This paper presents a modular, flexible, extendable and fast-computational framework that
implements a multidisciplinary, varying fidelity, multi-system approach for the conceptual …

The parallel hybrid (or boosted) turbofan engine alleviates the system complexity of radical
electrified powertrain architectures, while also demonstrates substantial benefits in reducing …

Classic gas turbine design relies on the definition of a design point, and the subsequent
assessment of the design on a range of off-design conditions. On the design point, both …

Electrically-driven ducted fans (e-fans), either underwing-mounted or located at the aft-
fuselage, can potentially improve the system overall efficiency in hybrid-electric propulsion …

Turbofan engines with ultra-high bypass ratio require more aggressive nacelle designs to
limit the drag and weight associated to the increased fan diameter. Reducing the inlet length …

A parallel hybrid configuration is a feasible means to reduce fuel consumption of gas
turbines propelling aircraft. It introduces an electric drive on one of the spools of the gas …

Gas turbine fuel burn for an aircraft engine can be obtained analytically using
thermodynamic cycle analysis. For large-diameter ultra-high bypass ratio turbofans, the …

In the context of an engine design calculation, isentropic or polytropic efficiencies of
turbomachinery components are assumed at the outset of the cycle analysis and their values …
