PARIS (ESA PR) — ESA’s Prometheus is the precursor of ultra-low-cost rocket propulsion that is flexible enough to fit a fleet of new launch vehicles for any mission and will be potentially reusable.
At the Space19+ Council meeting in Seville, Spain last November, ESA received full funding to bring the current Prometheus engine design to a technical maturity suitable for industry. Developed by ArianeGroup, Prometheus is now seen as key in the effort to prepare competitive future European access to space.
This first test lasted 30 seconds and was carried out on 26 May 2020 at the DLR German Aerospace Center’s Lampoldshausen testing facility. Additional tests are planned next week. The data from this test campaign will be collected and analysed.
This fully 3D-printed thrust chamber is built in just three parts and could power the upper stages of future rockets.
Additive layer manufacturing also known as 3D-printing, allows more complex designs for higher performance, vastly reduces the number of parts in this case from hundreds to three, and speeds up production time. This reduces costs and significantly improves the competitiveness of liquid propulsion engines for European launch vehicles.
This fullscale chamber has a 3D-printed copper liner with integrated cooling channels and a high-strength jacket built on via cold-gas spraying. Its manifold and single-piece injector head are also 3D-printed.
The production and test of these parts has been performed within ESA’s Future Launchers Preparatory Programme.
Three years after the last ESA Council Meeting at Ministerial Level, held in Lucerne, Switzerland, government representatives from the 22 Member States met in Seville, Spain, on 27 and 28 November 2019 and committed a total of almost 14.4 billion euro [$15.87 billion] for space programmes over the next few years.
Germany is contributing 3.3 billion euro [$3.6 billion] to ESA programmes focusing on Earth observation, telecommunications, technological advancement and commercialisation / NewSpace.
At 22.9 percent, Germany is now ESA’s largest contributor, followed by France (18.5 percent, 2.66 billion euro), Italy (15.9 percent, 2.28 billion euro) and the United Kingdom (11.5 percent, 1.65 billion euro).
The ESA Council Meeting at Ministerial Level is the highest political decision-making body, and it defines the content and financial framework for ESA’s space programmes every two to three years.
