We like being first.


Project Phoenix is the first of its kind.

It is the world’s first liquid hydrogen-powered two-seater motor glider, and the first of its category to have a range greater than 2000km. This incredible innovation allows the pilot to fly from the Netherlands to almost any other part of Europe on one tank of hydrogen! Leave conventional fuels on the ground and take off releasing nothing but water vapour into the atmosphere. And if the weather is exceptionally good, turn the engine off and glide like a sailplane!

Project Phoenix is also the first aircraft to fully implement a boundary layer suction system on both wings. This radical drag reduction system promises to reduce Phoenix’s drag and fuel consumption by up to 10% in comparison to other aircraft of its type. In gliding conditions, the suction system also results in a 10 point improvement in glide ratio, allowing Phoenix to challenge sailplanes of the open class. And the best part? The system is run using excess power from the hydrogen engine or power stored in its batteries!

Hello sustainability.


Since the first flight of a powered aircraft around 120 years ago, the aviation industry has boomed. Currently, 2.4 billion passengers fly around the world annually. But this has come at a cost. The industry is now responsible for over 2% of global CO2 emissions and continues to rise.

There have been many attempts to make aviation sustainable. Notable examples include the Solar Impulse, the first solar-powered aircraft to fly around the world, and the e-Genius, a fully-electric motor glider developed at the TU Stuttgart in 2010. The e-Genius was also the starting point for our own development – Phoenix is based on the structural and aerodynamic design of the e-Genius, and will be made using the same moulds!

Hydrogen powered flying devices have been experimented with for the last 40 years, and current developments in fuel cell technologies have made them more attractive than ever for this application. Our goal with this project is to show that flying on hydrogen power can be achieved. Not from a scientific point of view, but from a business point of view. We want to make the future sustainable.

Hello Europe.


Phoenix is designed for Europe. No matter your destination, Phoenix can reach all of Europe with a single fill of hydrogen. The vineyards of northern Italy, the sandy beaches of Greece or the mountains of Norway, all of these destinations are within 2000km of the Netherlands.

With comfortable upholstery and an intuitive autopilot being planned, Phoenix has the possibility of being used for business trips as well as pleasure. Flying at night or in instrument conditions will also be a possibility for future members of the Phoenix family.

Beat the traffic and experience Europe from above. What will you discover?

Hello efficiency.


A major step towards a cleaner future in aviation will be helped by an active drag reduction system. This system consists of a pump which sucks the layer of air slowed down by friction on the wing, known as the boundary layer, and ejects it into the wake of the aircraft. This technology was theorised as early as the mid-1800s and research done by Professor Loek Boermans at the TU Delft has allowed estimations into its advantages.

We have great hopes in this technology, whose potential has not yet been fully explored. We aim at reducing our drag and fuel consumption by up to 10% in comparison to other motor gliders by using this feature.
