Our future flies in clean skies

Clean Our Skies

The first aircraft took to the skies just over 100 years ago. Now, over 23,000 aircraft carry more than 4 billion passengers around the world every year. But bringing the world closer together has come at a cost.

AeroDelft is a TU Delft student team with one mission: prove that emission-free aviation is possible by developing the world’s first manned liquid hydrogen-powered aircraft.

Our Vision

Sustainable aviation is the only way. We see liquid hydrogen as the key towards a future with sustainable aviation.

Our Mission

To prove and promote liquid hydrogen as an alternative to conventional aviation fuel, to inspire the aviation industry to make the change on a scale that will result in worldwide sustainable aviation.

Although our aircraft is small, our ambition is not

We understand that not flying is not an option. We must make aviation sustainable, and increasing an aircraft’s efficiency is simply not good enough anymore. It is time for something far more radical: changing the fuel. 

We believe our efforts with hydrogen will kick-start the development of larger, commercial aircraft.

Stepping Stone Towards a Sustainable future

Prototype Phoenix is a 1:3 scale of the E-genius airplane, with a maximum take-off weight of 45 kg and a wingspan of 5.7m. Currently, we are working on our first flight on batteries, and we are expecting to integrate all the gaseous internal systems before the summer and make our first gaseous flight in the summer of 2022.

World’s first liquid hydrogen powered aircraft

Full-Scale Phoenix is a 2-seater Sling 4 aircraft, with a maximum take-off weight of 920 kg and a wingspan of 10m.  In July 2021, we received our Sling 4 kit which enabled us to start working on integrating all the systems to be able to fly our first Full-Scale flight.
