Powered by a fuel cell, the electric airplane HY4, developed by German researchers, has a range of over 750 km. This four-seater, strange-looking, made its first flight. The goal is to design a regional airliner of 19 places “zero emission”.Behind this project: Airbus, Siemens and 20 universities
A strange craft took off September 29, 2016 from Stuttgart Airport. This device twolooks like two airplanes, like brothers , are interconnected by a common wing with an engine and a propeller. The HY4 makes little noise: the engine, 80 kW, is electric. Take-off phase in which consumption is significant, it is a that provides electricity. But in flight, a , drawing the in a tank maintained at low temperature, produces by reaction with from the and releases water vapor. Results announced but validate: 145 km / h cruising 200 km / h in peak and a range of 750-1000 km.
Certainly, theis not a novelty. Many manufacturers, large and small, are trying it for years and no introduction shipping has completed a world tour with the solar.The use of a for supplying electricity to an is not new either. In 2007, we presented the , a model become “HyFish” once with an electric motor and a fuel cell. The transformation had already taken place in Stuttgart, in the workshops of the , Deutsches Zentrum für Luft- und Raumfahrt , an aeronautical research institute.
The electric aircraft hydrogen, issue a large research program
German engineers have persisted. University of Ulm researchers got their hands in the dough and the DLR is engaged in an extensive research program on electric aviation, with industrial partners such as Airbus and . The HY4 is based on an electric aircraft trade, the of the Czech company Pipistrel. This Taurus is actually a “glider” that is to say a with a massive 14.97 m and a low power motor (30 kW cruise, in this case). Team , who leads the project, brought together two Taurus, to bring the engine, the fuel cell and battery, achieving a total of 1,500 . The method is ingenious and avoided building a plane from scratch, as did the team of .and as scientific support using 20 universities and research centers of
The result is a four-seater, which is exceptional for an electric plane. The ultimate goal however is not to provide a recreational glider. Airbus and Siemens are working the topic of electric aviation for many years. Airbus has for example made the prototype , saying that the electric motor suit small aircraft taxis for short distances, regionally, until “19 seats” . Then remains to find ways to produce large amounts of hydrogen, possibly other than with plants . These aircraft would then be truly “zero “., presented at the last Paris Air Show, is studying the fuel cell for its and always says work on the project of a low-capacity transport aircraft. DLR says the same thing in his
