Fuel cell propulsion systems are not only being developed for unmanned aircraft, hydrogen is also increasingly becoming a topic in passenger transport. The US space agency NASA, for example, together with the engineering school of the University of Illinois, is constructing electric aircraft using liquid hydrogen and fuel cells.
Launch of Emission-Free Passenger Aircraft Hy4
A unique aircraft with a distinctive design and innovative engine technology – that is how one could sum up the features of the Hy4, which the German Aerospace Center (DLR) had already showcased at the World of Energy Solutions on Oct. 12, 2015. The new concept study was presented by project head Professor Josef Kallo, who had already been responsible for developing its predecessor.
