The global space market is more dynamic and diverse than ever. At the same time, today's European launch strategy is characterized by significantly shorter development times and cost-cutting technologies. The DLR Institute of Space Propulsion is ideally positioned for these developments: As a European research and test center for liquid propulsion systems, it has ideal framework conditions and high-quality test facilities. These cover the entire portfolio for engine tests of all sizes and specifications. In addition, there is even better networking and cooperation between aerospace companies, start-ups and research. Another advantage: the close integration of basic research with test operations enables us to exploit the full potential of rapid technology development.
Technical generation change for more efficiency in the test benches
With the FLAME (Future LAMpoldshausen Exploitation) project, DLR is developing the foundations for the comprehensive modernization and digitalization of the engine test stands as part of an ESA programme initiated by the German Space Agency at DLR. In this way, it is further expanding the strategic importance of the Lampoldshausen site for European space transportation. The focus is primarily on the increased standardization of interfaces, the use of Artificial Intelligence (AI) for test bench applications and digitally adapted structures and processes. The conditions for this are unique at DLR Lampoldshausen, as an extensive and high-quality database from decades of test bench operation forms the basis.
Cooperation with start-ups
In addition to the European launcher Ariane, microlaunchers are increasingly supplementing the range of launch options for loads of different weights. Microlaunchers are often developed by young companies and have a much shorter development time. With extensive expertise and a flexible test infrastructure, DLR is ready to support these processes and drive forward technological developments.
Particular emphasis is placed on the promotion of young scientists. To make this possible, the M11.5 test field was established in 2013. Students can test their self-developed rocket engines under expert supervision as part of the DLR-STERN program. The program also promotes the spin-off of start-ups.
Expansion of the test infrastructure for hydrogen technologies
A prerequisite for the successful further development and application of hydrogen technologies is a modern test infrastructure. This is being established in the Zero Emission – Hydrogen Site Lampoldshausen and HYDROGENIUM projects and strengthens DLR in Lampoldshausen in its role as a technology and development partner. Hydrogen-based systems and components such as compressors, tanks or micro gas turbines can be tested and further developed at several test locations. Thanks to its modular design, the test infrastructure can be flexibly adapted – depending on the order and research project.
The European Test Center
The global space market is more dynamic and diverse than ever. At the same time, today's European launch strategy is characterized by significantly shorter development times and cost-cutting technologies. The DLR Institute of Space Propulsion is ideally positioned for these developments: As a European research and test center for liquid propulsion systems, it has ideal framework conditions and high-quality test facilities. These cover the entire portfolio for engine tests of all sizes and specifications. In addition, there is even better networking and cooperation between aerospace companies, start-ups and research. Another advantage: the close integration of basic research with test operations enables us to exploit the full potential of rapid technology development.
The tests with the complete Ariane 6 upper stage will take place on the ESA P5.2 test stand specially developed for this purpose – an infrastructure that is unique in Europe.
Test of a LOX/methane technology demonstrator on the P3 test bench
LOX/methane engines promise great potential in the development of cost-effective and reusable high-thrust rocket engines. After researching this fuel combination at DLR Lampoldshausen since 2016, DLR is now working on making its large-scale test benches fit for complete LOX/methane engines.
