Commendation: RWTH Aachen with EcoAir
RWTH Aachen University presented EcoAir, an aircraft capable of carrying 76 passengers over a distance of 900 kilometres. The concept is based on a hybrid-electric propulsion system that uses liquid hydrogen fuel cells and batteries. To achieve a high level of aerodynamic efficiency, EcoAir features folding wingtips that create a large wingspan without compromising its compatibility with airport infrastructures. The wing is also equipped with a ‘hybrid laminar flow control system’, in which the turbulent boundary layer is sucked through the wing skin to reduce frictional resistance.
