HYDRA-X demonstrates the potential of modular hydrogen propulsion systems for the aviation of tomorrow.
At the tenth DLR Design Challenge, the student team from RWTH Aachen University achieved third place with their aircraft concept HYDRA-X. A total of 16 teams developed concepts for a novel small aircraft that could be used in the future as a flying testbed for aviation technologies.
HYDRA-X is designed as a modular research platform. The aircraft is intended to allow for the comparison of different hydrogen propulsion systems under real flight conditions: a fuel cell and a shaft power turbine. Both propulsion variants utilize the same airframe and a system of ten electrically driven propellers and can be interchanged quickly. Additional modular elements, such as those at the wingtips and nose, provide space for future sensors and research equipment.
With this challenge, the German Aerospace Center (DLR) promotes the development of practical concepts and the next generation of scientists and engineers. Flying test vehicles can help to test new technologies earlier in combination, to collect data under real-world conditions, and to identify risks before later application in commercial aviation.
The team from TU Berlin took first place with their HYDRA concept, while TU Braunschweig came in second with KANGAROO. The three winning teams will present their designs at the German Aerospace Congress 2026 in Aachen.
