    The future European launcher, Ariane 6, is scheduled to lift off for the first time in 2020. To ensure that all its payloads can be safely transported into orbit, the engines for the new launcher must first undergo extensive testing. A new facility at the German Aerospace Center (DLR) site in Lampoldshausen has been built to test the upper stage of the new launch vehicle. On this test stand, entire upper stages can be tested. The facility is unique in Europe.

  • Flexible, adaptable and cost-efficient – with the new P5.2 upper-stage test stand, the DLR site in Lampoldshausen is expanding its portfolio for all liquid-fuelled, chemical space propulsion systems in Europe.
  • The Ariane 6 test stand provides unique opportunities for the refuelling and qualification testing of the cryogenic upper stage.
  • Around 140 experts from space agencies, industry and science attended the inauguration of the upper-stage test stand during the 7th Industrial Days at the DLR site in Lampoldshausen on 26 February 2019.
  • Focus: space, space transport, Ariane 6

The future European launcher, Ariane 6, is scheduled to lift off for the first time in 2020. To ensure that all its payloads can be safely transported into orbit, the engines for the new launcher must first undergo extensive testing. An important step in the upper-stage testing of the new launcher was taken on 26 February 2019. At the DLR site in Lampoldshausen, the new P5.2 test rig was officially inaugurated by Pascale Ehrenfreund, Chair of the German Aerospace Center (Deutsches Zentrum für Luft- und Raumfahrt; DLR) Executive Board, Daniel Neuenschwander, Director of Space Transportation at the European Space Agency (ESA), and Pierre Godart, CEO of ArianeGroup GmbH, in the presence of numerous space policymakers and representatives from industry and academia. In future, the P5.2 test stand will be used to test cryogenic upper stages under sea-level conditions. What is special about this test rig is that not only engines and their components can be tested – as is the case with the site’s other test stands – but also the entire cryogenic upper stage of Ariane 6, the ‘Upper Liquid Propulsion Module’ (ULPM).

“The new test stand is one of the largest projects in the history of the DLR site in Lampoldshausen and unique in Europe. It is our answer to the new demands of global space transport – quickly adaptable, flexible to use and cost-efficient. This test stand therefore reflects the strategic and economic significance of European space transport and is makes a significant contribution to maintaining reliable, competitive and independent access to space,” says Ehrenfreund.

“The DLR Institute of Space Propulsion is an important member of the space cluster in Baden-Württemberg, which comprises over 80 companies, universities and research establishments. This cluster includes major names such as ArianeGroup at the Lampoldshausen site, Airbus DS and Tesat, as well as many SMEs, and currently employs more than 4000 people,” says Ministerial Director Michael Kleiner, Department Head at the State Ministry of Economics, Labour and Housing (Ministerium für Wirtschaft, Arbeit und Wohnungsbau) for Baden-Württemberg, who was represented at the ceremony by Claus Mayer.

DLR unlocks the potential of flexible test stands

This highly complex and extremely capable facility was designed and built as part of the development of the Ariane 6 launcher, directly commissioned by ESA. The test stand is financed by German ESA contributions to the Ariane 6 development programme. The DLR Space Administration is responsible for managing and coordinating these funds on behalf of the German government. “In times of disruptive change in the global space industry, where the competitive environment is becoming ever more complex due to new players, and the pace of innovation in advanced technologies is rapidly increasing, a modern and effective development and test site for liquid-fuelled, chemical space propulsion systems is crucial for the future viability of German and European spaceflight,” says Walther Pelzer, Member of the DLR Executive Board and Head of the Space Administration, adding: “The flexible use of test stands will therefore become the pivotal point for more efficient development and qualification processes in space systems.“

Complete stage tests for shorter development times

The foundation stone for the P5.2 test stand was laid in autumn 2014, together with the project partners. Commissioning by the DLR Institute of Space Propulsion is scheduled for late 2019. A total of around 50 million euro have been invested. “This uniquely designed equipment allows DLR engineers to conduct both refuelling and defuelling, as well as complete stage tests, in which the upper-stage engine is operated,” explains Hansjörg Dittus, DLR Executive Board member for Space Research and Technology. At no other European space site is there such a close linking of research, development, design and planning, as well as engine testing on large test stands for space propulsion systems, as at the DLR site in Lampoldshausen: “This shortens development times and significantly increases the maturity of liquid-fuelled, chemical space propulsion systems. In order to ensure the continuity for the site after Ariane 6, the test stands will be upgraded to methane combustion,” adds Dittus. The scheduled major investment of 30 million euro supports the European plans to develop the new Prometheus methane-fuelled engine.

The testing of all European liquid-fuelled chemical space propulsion systems is one of the central future activities at DLR Lampoldshausen. The engines for the new European Ariane 6 launcher will complete many thousands of test seconds on the test stands in Baden-Württemberg prior to their lift-off into space. “The future of the European launcher family and the future of the DLR site are closely linked. We are building on 60 years of experience and our aim is clear – for our test stands to enable us, as a European research and testing centre, to implement all the necessary test campaigns for Ariane’s liquid-fuelled chemical propulsion systems, from development, through qualification, to acceptance tests,” says Stefan Schlechtriem, Director of the DLR Institute of Space Propulsion.

From small test stands for trialling components and technology demonstrators, to large-scale facilities, such as those required for main and upper-stage launcher engines, everything is centrally available in one place at the DLR site in Lampoldshausen.

7th Industrial Days

The official inauguration of the new test rig also marked the beginning of the annual ‘Industrial Days’. With the slogan ‘Testing and test infrastructure to secure Europe’s flexible and affordable access to space’, almost 140 experts exchanged views on the progress of space transport on 26 and 27 February 2019. “The discussions showed that it is not only new engine component manufacturing techniques, but also test structures as a whole that are crucial to success in spaceflight. For reliable, independent and affordable access to space, we cannot rely on the structures of the past. In Lampoldshausen, we already have all the necessary facilities for developing and operating both Ariane 6 and all future space propulsion systems,” concludes Stefan Schlechtriem, who was invited to the Industrial Days in Lampoldshausen for the seventh consecutive time.


  • P5.2 – Europe’s new upper-stage test stand for Ariane 6 and beyond

    DLR’s Lampoldshausen site operates unique test stands and facilities for testing space propulsion systems; these are vitally important for the European space industry. This equipment covers the entire portfolio of test requirements. As a European research and testing centre, DLR therefore concentrates important expertise with the aim of developing and testing new technologies for liquid-fuelled, chemical space propulsion systems in a single location.
    The completion of the P5.2 test rig for the new upper stage of the future European launcher, Ariane 6, gives Germany another important technological advantage. It will allow DLR to qualify not only engines and individual components, but also entire cryogenic upper stages in future – a pioneering test facility in Europe that highlights DLR’s leading position in this area.

  • The DLR Institute of Space Propulsion

    The DLR Institute of Space Propulsion at the DLR site in Lampoldshausen operates large test stands for space propulsion systems. These facilities cover the entire portfolio of test requirements, from component testing, through engine tests, to trialling entire rocket stages. It conducts research and development, as well as qualification and characterisation tests. DLR engineers are currently testing the main stage engine, Vulcain 2.1, and the upper-stage engine, Vinci, for Ariane 6 on the P5 and P4.1 test rigs on behalf of ArianeGroup. These tests are a major milestone in the development of the future European launcher, Ariane 6, which will continue to secure Europe’s independent access to space.
