Test run completed for a 250-ton Typhoon rocket engine's preburner, as German company's component endured 16 high-temperature burns
The Exploration Company has announced a major advancement in the development of the Typhoon engine, a full-flow staged combustion rocket. The engine underwent 16 hot-fire tests at the German Aerospace Center (DLR) Lampoldshausen site, marking a significant improvement over earlier tests.
These tests, conducted across four configurations of the Typhoon engine's oxygen-rich preburner, resulted in stable combustion runs lasting up to 85 seconds. This is a notable improvement over earlier tests, which were limited to 16 seconds due to hardware failures and low-frequency instabilities.
The successful tests followed a six-week campaign on the P8 test bench at DLR Lampoldshausen, demonstrating progress in overcoming combustion instability issues. The DLR Institute of Space Propulsion expressed appreciation for the productive cooperation on the Typhoon engine development.
The Typhoon engine, designed to produce 250 tonnes of thrust, is comparable to SpaceX’s Raptor engine. Successful stable operation of the oxygen-rich preburner is critical because it drives the engine's turbopumps, ensuring high-pressure propellant flow to the combustion chamber.
However, despite this technical progress, the future application of the Typhoon engine remains uncertain. It is too powerful for The Exploration Company’s current in-space logistics missions, and no confirmed usage has been announced.
The Exploration Company has partnered with an industrial prime to submit a proposal for the European Space Agency’s European Launcher Challenge, likely including the Typhoon engine. However, no public updates confirm whether this bid progressed or what the engine’s eventual role might be.
The Typhoon engine is a reusable engine, co-financed by the French space agency CNES. It uses a full-flow staged combustion cycle, similar to the SpaceX Raptor family, which powers the Starship system. The Starship is powered by six engines, three Raptor engines, and three Raptor Vacuum engines, designed to fly in vacuum.
The tests took place at the P8 research and development test bench at the DLR site in Lampoldshausen. The Typhoon engine component has been in development since 2024. The preburner of the Typhoon engine powers a rocket engine's turbopumps, which feed fuel and oxidizer into the combustion chamber at high pressure.
While the test campaign marks key technical milestones, the strategic and operational path forward for this engine has yet to be defined. The Typhoon engine's future applications and role in The Exploration Company's projects remain to be seen.
- The successful tests on the Typhoon engine in robotics and aerospace have shown promise, making it comparable to the SpaceX Raptor engine in terms of thrust.
- The Typhoon engine, which is currently co-financed by the French space agency CNES, has undergone development since 2024, including the preburner that powers the engine's turbopumps for energy-efficient propulsion.
- While the advancements in the Typhoon engine's combustion cycle are significant, its uncertain future in the industry depends on a successful bid for the European Space Agency's launch challenge, as well as finding the appropriate application within The Exploration Company's projects.
- The potential integration of the Typhoon engine in space-and-astronomy projects could bring about a new era of innovation in propulsion technology, contributing to a more sustainable and efficient space industry.
