Sustainable flying of the next generation – The Sling High Wing with hydrogen propulsion!
From the same team who bought you the e-Sling, we are excited to introduce this year’s Cellsius Aero focus students! Together with their sponsors, freelancers and mentors from previous years, these youth are more motivated than ever to celebrate their first flight next summer as part of Project H2!
Their goal is to enable sustainable aviation. That’s why they are the first student team to build an aircraft powered by hydrogen. They are using our latest kit aircraft, the Sling High Wing. Thanks to the high energy density of hydrogen, they hope to achieve market-ready performance:
2 hours of cruising flight – Their H2 Sling will fly for a total of two hours.
200 km – Thanks to a range of 200 km, the whole of Switzerland can be reached from Zurich.
0g CO² – A hydrogen aircraft that does not emit CO².
Implementation:
Many in-house developments of components enable them to achieve the highest compatibility and the lowest possible weight – two crucial factors in maximising the efficiency and range of the aircraft. At the same time, they are committed to the highest safety standards. Every component, from the inverter to the modular battery, has been intensively tested to meet the demanding requirements of aviation.
The System:
Their innovative drive train is made up of numerous technical sub-modules that must work together seamlessly and precisely to get their aircraft into the air. These individual components that are installed in their system include:
The Plane:
Their new drive is installed in our Sling High Wing aircraft kit. To ensure that it fits perfectly, modifications are made to the airframe. The drive train is specifically tailored to the airframe.
The Fuel Cell System:
The heart of their drive train is a hydrogen fuel cell with 92 kW of power. It supplies the energy needed for a flight from hydrogen. In order to operate the fuel cell under all environmental conditions, various components are needed to regulate pressure, temperature and humidity.
The Tank System:
The gaseous hydrogen is carried on board the aircraft in several pressure tanks at 700 bar. This allows them to achieve a flight time of two hours.
The Buffer Battery:
To absorb power peaks during take-off or a go-around, they will install a modular battery system with a total capacity of 5.8 kW. The batteries are liquid-cooled and can be recharged by the fuel cell during flight.
The Motor:
An efficient and powerful electric motor is essential for their aircraft to take off. The radial flux electric motor developed in partnership with E+A is a special development that is optimally tailored to their requirements.
Power Electronics:
To operate the AC motor with batteries and a fuel cell, a power converter is required. They developed this themselves so that it fits perfectly with their motor and their requirements.
