WHAT IF WE CAN
MAKE AVIATION
SUSTAINABLE?

By combining a team of young and clever minds with leading-edge companies, we want to show the world that this reality lies within reach with our two liquid-hydrogen-powered aircraft.

The full-scale
phoenix

Full-Scale Phoenix will be a manned liquid hydrogen powered plane, set to fly on liquid hydrogen in 2026.

It’s a 2-seater Sling 4 aircraft powered by hydrogen fuel cells. No combustion required.

This makes it able to be 100% emission-free, something which planet earth loves.

The Prototype is a fundamental part of Project Phoenix that allows us to get familiarized with liquid hydrogen.

Testing the Prototype will allow us to create the best and most efficient version of the Full-Scale Phoenix.

connecting,
not polluting

1 / 6

Imagine a world where being connected with each other by flight does not pollute the environment we connect in. It sounds like an ideal. However, the Phoenix is the first step to show it is attainable. It will create a level of freedom that is unbound by pollution.

BECOMING
INDEPENDENT

Independence from fossil fuels is becoming increasingly important as current times show access to fossil fuelsfuel can become limited.

Hydrogen can be of aid here. In aviation particularly, we believe liquid hydrogen is the key to make flight sustainable.

REMOVING
FLIGHT SHAME

3 / 6

Flight shame doesn’t exist in the Phoenix.

With a full tank of just 10kg of liquid hydrogen it can enjoy nearly three hours of flight that makes it travel a distance of nearly 400km.

These endurance and range values are unmatched by batteries and conventional fuels.

Possibilities

Although our aircraft is small, our ambition is not. For example, we are working internationally to develop certification guidelines for hydrogen propulsion. We firmly believe that our work will demonstrate the scalability of liquid hydrogen.

safety
first

5 / 6

Safety is AeroDelft's number one priority. Our aircraft resembles that. And to help the industry we are working internationally to develop certification guidelines for safe hydrogen propulsion.

pushing
the envelope

6 / 6

Wide-scale change will only happen when everyone works together.

To make this challenge easier AeroDelft is clearing a path towards a common goal of sustainability.

We hope to inspire people, engineers, and the industry as a whole to move forward and push further than the standard we’re setting in aviation right now by building our Full-Scale Phoenix aircraft.
