Research aircraft

Modern sailplanes like our Antares are characterized by an outstanding performance. Their sophisticated aerodynamics allow for low power propulsion systems. Consequently they are well suitable as scientific test devices for many explorations and applications, which may also help for the improvement of airliners.

Together with the German Aerospace Center (DLR) Lange Aviation GmbH has designed the fuel-cell experimental Antares H2, which has been able to celebrate its successful maiden flight in April 2009. For the first time in history a manned aircraft had accomplished a complete cycle from take-off till landing exclusively powered by a fuel-cell power plant.

Motivated by these achievements we have founded Lange Research Aircraft GmbH. The next step in evolution will be the Antares H3. The project was launched in August 2010 and it reveals a giant step forward. At the same time it proves the practical benefit of our propulsion system. As seen before on our Antares H2, the new research aircraft is mostly based on components of our Antares-series.

While the antecessor could only carry one fuel-cell unit and one fuel-cell tank in two aerodynamically shaped containers under its wings, the Antares H3 is equipped with two forward-looking fuel-cell systems which enlarges the aircraft’s range from 500 to about 5,400 km. The flight time can now be up to 40 hours. The aircraft’s structure with an enlarged wingspan of 23 meters was configured to a maximum take-off weight of 1,650 kg. As a result it may carry a payload of 200 kg.

We have thus set new benchmarks. The Antares H3 is the perfect basic platform for a number of manned and unmanned civil missions in visual and sensory earth observation and for remote sensing.

Synergies are obvious: at Lange Aviation development for research and research for evolution work hand in hand. To their two-way advantage.
