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.
A review in September 2019 marked the culmination of two Vulcain static firing test campaigns over 15 months on two demonstration models in test facilities at the DLR German Aerospace Center test facility in Lampoldshausen.
The final qualification static firing test of Vulcain 2.1 in July lasted almost 11 minutes (655 seconds). This completed a total of 13,798 seconds of operation, or nearly four hours with a controlled engine, using Ariane 6 flight actuators to gimbal the engine.
The engine will be refurbished for dynamic and vibration tests. Combined tests using a fully representative main stage at Europe’s Spaceport in French Guiana, will finally qualify the Ariane 6 core stage for flight.
