Companies are turning to alternative energy sources because of the problems caused by petroleum-based fuels. Stuttgart-based aviation company H2FLY, He broke the world record with the hydrogen-fueled passenger plane he developed.
The automobile and aviation industry has accelerated its efforts for alternative energy sources. Companies such as BMW, Renault and Volvo continue their R&D activities for hydrogen fueled vehicles. In the aviation sector, companies, especially electric helicopters, started to use alternative energy sources in many areas.
Tests for Starlink on the plane have started! Here is the first airline
Preliminary tests have begun for the use of Starlink, SpaceX’s satellite internet service, on aircraft. Here are the first details for Starlink on the plane!
Hydrogen-fueled passenger plane traveled 124 km
The company, which made a flight from Stuttgart to Friedrichshafen on April 12, 124 km traveled the way. The aircraft, which can reach an altitude of 7,000 ft (2,134 meters), has a capacity of four people.
The HY4, which took off for the first time in 2016, has a unique double hull design. Based on the Pipistrel Taurus G4 aircraft, the model was designed as a hybrid.
Electric flight uses a low-temperature hydrogen fuel cell system developed by the DLR Institute for Engineering Thermodynamics (DLR). The aircraft has two carbon composite tanks, one in each fuselage.
Lithium-ion batteries together with the composite tanks feeding the fuel cells come into play when the demand for the 80 kW electric motor is at its highest. The aircraft has a cruising speed of 145 km/h and a range of 1,500 km under minimum load and optimum flight conditions.
