Vinci (rocket engine)


Vinci (rocket engine)

Vinci is a European Space Agency cryogenic rocket engine currently under development. It is designed to power the new upper stage of Ariane 5, ESC-B, and will be the first European re-ignitable cryogenic upper stage engine, raising the launcher's GTO performances to 12 t.

Overview

Vinci is an expander cycle rocket engine fed with liquid hydrogen and liquid oxygen. Its biggest improvement from its predecessor, the HM-7B (which powers the ESC-A), is the capability of restarting up to five times. It is also the first European expander cycle engine, removing the need for a gas generator to drive the fuel and oxydizer pumps. It 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.

Development

Although the ESC-B development has been put on hold in 2005, the Vinci project has not been cancelled: at a lower pace, the engine is still being developed. In 22 December 2006, Snecma announced a new ESA contract for Vinci rocket engine long-duration and re-ignition testing.
