Preliminary sizing methodologies for regional aircraft with liquid hydrogen fuel and SOFC-GT-Battery hybrid-electric powertrains

Solid Oxide Fuel Cell (SOFC) systems for aviation applications have been considered for their use as APUs or powertrains, as standalone systems or in combination with gas turbines, and both fueled by reformed Jet-A or by hydrogen. Most existing studies focus on powertrain performance modelling. In this work, traditional tube-and-wing regional...

An Assessment of a Regional Turboprop Featuring Wingtip-Mounted Propellers: Design Integration Coupling Propeller-Wing Aerodynamics and Structural Wing Weight

The current focus in the aviation industry for more sustainable designs, could mean the revive of propeller propulsion, due to their relative high propulsion efficiency compared to jets. In addition, the application of wingtip-mounted propellers installed in tractor configuration can be used as tip-vortex attenuating devices, reducing the wing...
