VERNON, France (Snecma PR) – The fifth development model (M5) of the Vinci® rocket engine designed by Snecma (Safran), has successfully completed its ground firing tests.

Vinci® is a new-generation cryogenic rocket engine – fueled by liquid hydrogen and oxygen – intended for the upper stages of the upcoming Ariane 5 ME and Ariane 6 launch vehicles. It can be restarted in flight, and develops three times more thrust than the HM7B engine now powering the upper stage of the current Ariane 5 ECA launcher.

Courcouronnes, France, September 30, 2013 (Snecma PR) — Snecma has kicked off a new series of tests of the Snecma (Safran) Vinci® cryogenic rocket engine intended for the upper stages of the new Ariane launchers, the upgraded Ariane 5ME (Midlife Evolution) and the brand-new Ariane 6. The first two tests of the No. 5 development engine, on September 10 and 26, were a complete success.

The Vinci® M5 variant features a hydrogen turbopump that incorporates the latest configuration changes. Lasting ten months, this series of tests will include a total of 16 firing tests and will enable validating the latest modifications in order to freeze the design by the end of 2014.
