A major breakthrough in the advancement of reusable rockets has been achieved by ArianeGroup, as they successfully conducted a test of the Prometheus engine at their facility in Vernon, France on June 22, 2023. This cutting-edge engine, boasting a thrust capacity of 100 tonnes, incorporates groundbreaking materials and manufacturing techniques such as 3D printing, resulting in a remarkable reduction in costs compared to its predecessor, the Vulcain 2 engine used in Ariane 5. The Prometheus engine operates on a highly efficient combination of liquid oxygen and liquid methane fuel, simplifying handling procedures and greatly enhancing reusability.
In a significant stride towards the development of reusable European rockets, ArianeGroup has demonstrated the Prometheus engine’s potential. This engine, belonging to the 100-tonne thrust class, harnesses the power of liquid oxygen and liquid methane fuel, while leveraging the advantages of 3D printing to achieve cost-effectiveness, cleanliness, and reusability. The engine is now mounted on a prototype reusable rocket stage named Themis, and further comprehensive tests will be conducted to evaluate its flight and landing capabilities. The Prometheus engine is expected to play a central role in the future generation of European launchers.
Continuing their efforts to create reusable engines for European rockets, ArianeGroup has achieved a significant milestone with the full ignition of the early Prometheus prototype. Captured on June 22, 2023, at ArianeGroup’s test facility in Vernon, France, these images showcase a 12-second burn that signifies a crucial step forward in space exploration.
The Prometheus engine, belonging to the 100-tonne thrust class, employs a range of advanced materials and manufacturing techniques that significantly reduce costs compared to its predecessor, the Vulcain 2 engine found in Ariane 5. The liquid oxygen and liquid methane fuel used in the Prometheus engine provide cleaner combustion and simplify handling procedures, thereby enabling reusability and reducing ground operation expenses before and after each flight.
Notable features of the Prometheus engine include its variable thrust capacity and multiple ignition capabilities. Leveraging the power of additive layer manufacturing, also known as 3D printing, the engine benefits from reduced part count, accelerated production, and minimized waste.
During the tests conducted in Vernon and Lampoldshausen, the Prometheus engine was mounted on a prototype of a reusable rocket stage named Themis, which is concurrently being developed alongside the engine. This engine-stage combination will undergo a series of “hop-tests,” involving short-distance ascents above ground level, to thoroughly evaluate its flight and landing capabilities.
Prometheus and Themis together represent the foundational components of a future family of European launchers, as envisioned by ArianeGroup. These remarkable technological advancements in reusable rocketry pave the way for an exciting future in space travel.
