AeroDelft is a student team with one mission: prove that emission-free aviation is possible by developing the world’s first liquid hydrogen-powered aircraft. We are executing our mission with Project Phoenix, by designing and manufacturing two aircraft; a 1:3 scale prototype and a full scale Sling 4 aircraft both powered by hydrogen. Our aim is to build the first manned aircraft to fly on liquid hydrogen to remove CO2 emissions altogether by using this very potent fuel source. In 2022, our prototype aircraft took to the skies on batteries and our full scale aircraft successfully taxied on a runway. The prototype aircraft is set to take off on hydrogen in 2023 and our full scale aircraft in 2025! Although our main goal is to build the first manned aircraft to fly on liquid hydrogen, we firmly believe that the aviation industry needs to follow our example to remove CO2 emissions from the aviation industry altogether.
