Vulcain 2 engine now in full production

06.04.2005


A small ceremony took place yesterday at the site of Snecma Moteurs in Vernon, France, to mark the beginning of industrial production of the Vulcain 2 engine, designed for the new Ariane 5 ECA and Ariane 5 ES ATV launchers.

Present at the ceremony was Patrick Devedjian, the French Minister for Industry and Jean-Paul Béchat, Chairman of the Executive Board of Sagem-Snecma. ESA was represented by Antonio Fabrizi, Director of Launchers and Robert Lainé, Head of the Ariane Department. “As the 12 February Ariane 5 ECA qualification flight was a complete success; we can now go into full production of the Vulcain 2 engine,” said Jean-Paul Béchat.

The Vulcain 2 is used for the main stage of the Ariane 5 ECA that can place payloads of up to 10 tonnes into geostationary orbit, and by the Ariane 5 ES ATV, designed to deliver ESA’s Automated Transfer Vehicle (ATV) to the International Space Station (ISS). Ariane 5 ES ATV’s maiden flight is planned for 2006. It will place the ATV into a 300 km circular low Earth orbit, inclined to 51.6 degrees, from where the ATV will use its own propulsion system to reach and dock with the ISS.



Vulcain 2 is a modification of the Vulcain cryogenic engine used by the Ariane 5 Generic launcher and has an increased thrust of 20%. The engine operates under slightly higher pressure than that used for the Ariane 5 G and with a mixture ratio of 20% more liquid oxygen. Its new oxygen turbopump operates at 13 000 rpm to deliver a pressure of 161 bar.

This redesigned engine also has a new nozzle and nozzle extension to allow exhaust from the turbopumps to be re-injected into the main system, thus improving engine performance at high altitudes. All these modifications mean that the Vulcain 2 engine can provide an additional lift capability of 1.3 tonnes into geostationary orbit.

During yesterday’s ceremony, those present met with the Vulcain 2 designers and technicians, and visited the test centre to see a Vulcain 2 engine, the first produced under a contract for 30 engines.

Antonio Fabrizi said after the ceremony: “This first contract for Vulcain 2 engines has been placed under the European Guaranteed Access to Space Ariane 5 Programme. It ensures that Ariane 5 launchers will be available for European missions.”

Im Focus: Giant Magnetic Fields in the Universe

Astronomers from Bonn and Tautenburg in Thuringia (Germany) used the 100-m radio telescope at Effelsberg to observe several galaxy clusters. At the edges of these large accumulations of dark matter, stellar systems (galaxies), hot gas, and charged particles, they found magnetic fields that are exceptionally ordered over distances of many million light years. This makes them the most extended magnetic fields in the universe known so far.

The results will be published on March 22 in the journal „Astronomy & Astrophysics“.

Galaxy clusters are the largest gravitationally bound structures in the universe. With a typical extent of about 10 million light years, i.e. 100 times the...

Im Focus: Tracing down linear ubiquitination

Researchers at the Goethe University Frankfurt, together with partners from the University of Tübingen in Germany and Queen Mary University as well as Francis Crick Institute from London (UK) have developed a novel technology to decipher the secret ubiquitin code.

Ubiquitin is a small protein that can be linked to other cellular proteins, thereby controlling and modulating their functions. The attachment occurs in many...

Im Focus: Polymer-coated silicon nanosheets as alternative to graphene: A perfect team for nanoelectronics

Silicon nanosheets are thin, two-dimensional layers with exceptional optoelectronic properties very similar to those of graphene. Albeit, the nanosheets are less stable. Now researchers at the Technical University of Munich (TUM) have, for the first time ever, produced a composite material combining silicon nanosheets and a polymer that is both UV-resistant and easy to process. This brings the scientists a significant step closer to industrial applications like flexible displays and photosensors.

Im Focus: Researchers Imitate Molecular Crowding in Cells

Enzymes behave differently in a test tube compared with the molecular scrum of a living cell. Chemists from the University of Basel have now been able to simulate these confined natural conditions in artificial vesicles for the first time. As reported in the academic journal Small, the results are offering better insight into the development of nanoreactors and artificial organelles.
