The first successful test firing of this campaign took place on. In late April 2010 the German Aerospace Center DLR announced the start of a six-month test campaign for the Vinci engine at its Lampoldshausen facility. On 22 December 2006, Snecma announced a new ESA contract for Vinci rocket engine long-duration and re-ignition testing. The engine features a carbon ceramic extendable nozzle in order to have a large, 2.15 m diameter nozzle extension with minimum length: the retracted nozzle part is deployed only after the upper stage separates from the rest of the rocket after extension, the engine's overall length increases from 2.3 m to 4.2 m.Īlthough the ESC-B development was put on hold in 2003, the Vinci project was not cancelled: at a lower pace, the engine is still being developed. It is also the first European expander cycle engine, removing the need for a gas generator to drive the fuel and oxidizer pumps. ![]() Its biggest improvement from its predecessor, the HM7B (which powers the ESC-A), is the capability of restarting up to five times. Vinci is an expander cycle rocket engine fed with liquid hydrogen and liquid oxygen. It is designed to power the new upper stage of Ariane 6. Vinci is a European Space Agency cryogenic liquid rocket engine currently under development.
