  • The three engines for Europe’s new Ariane 6 launcher have now completed their qualification tests, following the successful qualification testing of the P120C solid propulsion engine on October 7 at Europe’s Spaceport in French Guiana
  • The qualification test campaigns for the Vinci and Vulcain 2.1 liquid propulsion engines were held in 2018 and 2019, respectively
  • The Vulcain 2.1 and Vinci engines, which will be powering the first Ariane 6, are ready to be mounted on the core stage in Les Mureaux and on the upper stage in Bremen

PARIS (ArianeGroup PR) — The future European launcher’s three types of engines use two different propulsion technologies:

  • liquid hydrogen-oxygen propulsion for the Vulcain 2.1 core stage engine and the re-ignitable Vinci engine on the upper stage;
  • solid propulsion for the P120C engine fitted to the boosters which help propel Ariane 6 beyond the gravitational pull of earth’s atmosphere.

LAMPOLDSHAUSEN, Germany (ESA PR) — Ariane 6, Europe’s next-generation launch vehicle, has passed another key development milestone. Its Vulcain 2.1 liquid-fuelled engine has now completed its qualification testing, which means combined tests can now begin.

The main stage Vulcain 2.1 engine will deliver 135 t of thrust to propel Ariane 6 in the first eight minutes of flight up to an altitude of 200 km.
