A full-scale demonstrator of the thrust chamber for an upper-stage rocket engine incorporating the newest propulsion technologies has successfully passed first hot firing tests at the DLR German Aerospace Center P3.2 test facility in Lampoldshausen. The Expander-cycle Technology Integrated Demonstrator, ETID, will help to prove innovative technologies, materials and manufacturing techniques. It is tested in the frame of ESA's Future Launchers Preparatory Programme, aiming to increase the future competitiveness of European launchers by creating ready-made technical solutions, which can be transferred for quick development projects with minimal cost, effort and risk. Different technologies and methods of manufacture have been tested, such as additive manufacturing, laser ignition and cost-efficient materials. In addition, components will be tested to lay the foundations for a future 'smart' engine. Upper-stage engines operate in specific conditions such as vacuum and weightlessness that are difficult to reproduce on the ground, and involve significant development risks that have to be mitigated. By the end of the year, ETID will have been hot fired up to 20 times, each test run lasting 120 seconds, in conditions similar to those in space, with a near-vacuum provided by the test stand. Next to ArianeGroup in Germany, the prime contractor of this programme, other European partners like GKN Aerospace in Sweden, APP in the Netherlands, Safran Aero Boosters in Belgium and Carinthian Tech Research in Austria have, all provided hardware components for these demonstrator tests.
ESA Council commits to Ariane 6 and transition from Ariane 5 Paris (ESA) Jun 18, 2018 The ESA Council met in Paris this past weeek to discuss the path towards the future exploitation of Ariane 6. In view of the progress made in the Ariane 6 programme, Participating States have decided on the completion of the development up to full operational capability and agreed to fund industrial incentives associated with the development of Ariane 6 and P120C solid rocket motor. Participating States also committed to start with the first step of the Ariane 6 and P120C Transition Programm ... read more
