In Stuttgart, made its first 15-minute test flight four-passenger single-engine aircraft HY-4 with an electric motor running on hydrogen fuel cells. Another of its features – located on both sides of the engine two fuselage with passenger cabins.
The length of the aircraft is 21.36 meters. The unusual arrangement of HY-4, according to its developers, provides him with “optimal distribution of drive components and a higher overall load capacity.”
In each fuselage are 9-kilogram containers for hydrogen, which supply 4 low-temperature exchange membranes of fuel modules. All of them form a single system that converts hydrogen and oxygen into water and electrical energy.
The developers emphasize the point that hydrogen for fuel cells was produced with the help of renewable energy sources , which makes the HY-4 aircraft completely free of harmful emissions by transport.
The power of the electric motor (80 kW) is guaranteed to ensure flight, and lithium-polymer batteries will complement its efforts for take-off and climb. HY-4 is designed for a maximum range of 1500 km, which, however, can be adjusted depending on speed, altitude and load. The maximum and cruising speed is 200 and 145 km / h, respectively.
The car was created jointly by specialists of a small aircraft company Pipistrel, the company Hydrogenics (fuel system), as well as the University of Ulm and the German Aerospace Center of the Institute of Engineering Aerodynamics.
