AeroDelft is an interdisciplinary student team of more than 50 university students, with a mission to prove and promote liquid hydrogen as an alternative to conventional fuels in aviation. To realize this mission, we are designing and manufacturing two liquid hydrogen-powered aircraft. The Phoenix Prototype is an unmanned drone that will be the biggest aircraft ever to fly electrically on liquid hydrogen. The Phoenix Full Scale takes it a step further by realizing the first-ever manned liquid hydrogen-powered aircraft!
