Ariane 6 upper stage cryogenic connection system undergoes tests. Pyrotechnic actuators detonate to burst hinges open allowing the umbilicals to safely separate from Ariane 6. The supporting cryo-arms that hold the upper umbilicals then move out horizontally away from the launch vehicle to clear the way for liftoff
Mini-masts protect Ariane 6 lower-stage umbilicals. At liftoff, umbilicals that separate from the lower liquid propulsion stage are pulled back into two mini masts on the launch pad. Steel doors slam shut to shield this cryogenic connector system from the rocket exhaust as ascent begins. This all happens in split seconds in a highly precise, synchronized sequence
Ariane 6 complete upper stage. Integrated in October last year at ArianeGroup in Bremen, Germany, this ‘hot-firing model’ of the complete Ariane 6 upper stage is fully operational having undergone extensive functional tests. Its new reignitable Vinci engine is connected to two liquid hydrogen and oxygen tanks and is equipped with all lines, valves and electronic and hydraulic instrumentation and control systems
Vulcain 2.1 static firing test. 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
Vinci engine qualified in tests. Vinci is the re-ignitable engine of the upper stage that increases the operational flexibility of Ariane 6 and ensures that the engine safely deorbits at the end of the mission. This engine was successfully tested more than 140 times and reignited multiple times in succession in near vacuum to complete its qualification

With the help of ESA, RUAG Space developed an out-of-autoclave process where the carbon-fibre shells of the rocket fairing are cured in an industrial oven instead of an autoclave. It reduces cost and saves time. - The first fairing manufactured in this way was flown on Ariane 5, flight VA238 on 28 June 2017. Vega began using the new type of fairing on 1 August 2017. Ariane 6 and Vega-C fairings will also be produced in the same way.
