Successful first test of the Ariane 6 Vulcain 2.1 engine
The first hot firing of Ariane 6’s Vulcain 2.1 main engine was performed in January 2018 at the DLR German Aerospace Center test facility in Lampoldshausen, Germany.
The engine, developed by ArianeGroup, has a simplified and more robust nozzle, a gas generator made through additive manufacturing, and an oxygen heater for oxygen tank pressurisation. These features lower the cost of the engine and simplify manufacturing.

What is that's two exhaust pipe on each side of the reactor ?
Can we have a clip of the test firing with actual engine sounds, without music?
Record the sound of this motor please.
