HORIZON-JU-CLEAN-AVIATION-2026-04-HPA-04 - Demonstration of a hydrogen distribution system for a direct hydrogen combustion propulsion aircraft

Expected Outcome:Development and demonstration of the hydrogen distribution and conditioning system, from the tank interface until the combustor, for a direct hydrogen combustion propulsion aircraft. This topic targets the demonstration of the critical distribution and hydrogen conditioning components, including the high-pressure hydrogen pump, at TRL5, and the on-ground demonstration of the fuel distribution system at TRL4. The project will perform a scaled-on ground demonstration of the engine thrust control function. See the topic description document published with this call for full details.
