The INTERGEO, which takes place in Frankfurt from 16 to 18 October, offers the opportunity to become acquainted with aviation innovation such as the Antares E2 of Zweibrücker Lange Research Aircraft GmbH as part of the Interaerial Solutions Expo (IASEXPO).
The idea born in 2011 of conquering the airspace with hydrogen-powered aircraft is going into production for the first time with the Antares E2. Visitors will have the opportunity to see the unique technology live and learn about the components and the new opportunities that the Antares E2 opens up in direct conversation with the manufacturer. The iformation stand of Lange Research Aircraft GmbH will be open to the public throughout the show in Hall 12.0, Booth 12.0B.130, while the Antares E2 will be displayed on the upper floor of the Show Area.
As part of the Antares E2 project, Lange Research Aircraft GmbH is developing an electrically propelled aircraft that can be used for a variety of manned and unmanned observation, detection or surveillance tasks. The Antares E2 is characterized by its climate-friendly and CO2-neutral drive, an extraordinary long flight time of 40 hours, a high payload of about 200 kg and a multiple redundancy of all important systems that makes the aircraft much safer.
Another unique feature of the Antares E2 is its high reliability, which – combined with its standard equipment with optical, thermosensitive and multi / hyperspectral, imaging sensors – enables use in the maritime sector.
The majority of the international observation and surveillance missions have so far been flown by conventionally powered aircraft. With the Antares E2, the implementation of such missions is significantly more economical than previously possible due to significantly lower fuel consumption and lower set-up costs. This new economic efficiency paves the way for the implementation of new missions, which could not be flown for cost reasons, and also opens the market for other customer segments.
Energy is supplied to the Antares E2 based on fuel cells with an integrated methanol reformer. This system of fuel cell and reformer is superior to all conventional systems in terms of total system weight in terms of long-term energy draw since much more energy can be extracted from reformer fuel than internal combustion engines.
For supply at load peaks, e.g. at take-off and in climb, the aircraft is additionally equipped with a lithium-ion battery. The battery consists of approximately 24 modules, each with three individual cells, which are housed in the wing lobes of the inner wings. Each cell is redundantly monitored for voltage and temperature. In addition, the modules have battery heaters to keep the batteries in the optimum temperature range.
