WARR Space Robotics, the student aerospace organization at the Technical University of Munich, has completed a key pump test campaign for its bi-liquid electric pump-fed rocket development program known as Project Nixus, alongside a separate structural validation milestone involving composite pressure vessel flight testing.

The pump test campaign focused on validating the performance and reliability of the rocket s electric pump-fed propulsion system under operational conditions. The tests were conducted in collaboration with Hargrave Technologies, which supported the project by providing electronic speed controllers (ESCs) used to drive and control the pump system.

In a parallel development milestone, WARR also reported the successful flight of its student-built Type 5 composite pressure vessel, which launched aboard an EX-4C rocket at the European Rocketry Challenge (EuRoC) 2025. The flight demonstrated structural integrity and real-world performance of the composite pressure vessel under launch conditions.

The team also highlighted its use of TaniqWind Pro within its filament winding workflow over the course of approximately one year, supporting the development and manufacturing of composite pressure vessel structures for its rocketry systems.

The pump test phase forms part of WARR s broader efforts to develop advanced student-led rocket propulsion systems, including bi-liquid and solid rocket architectures, satellite technologies, and space robotics platforms.

According to WARR, the successful completion of the propulsion testing campaign demonstrates improved system robustness and supports continued integration toward flight-ready bi-liquid rocket systems.

The project reflects growing technical capability among university-level aerospace teams in developing complex propulsion and composite pressure vessel technologies typically associated with advanced launch vehicle systems.

WARR Space Robotics is one of Europe s largest student aerospace organizations and operates multiple sub-teams focused on rocketry, satellites, robotics, and microgravity research, with ongoing projects spanning experimental launch systems and space technology development.
