Scenes from the combined hot-fire test held for Ariane 6 on 23 November 2023. Teams on the ground went through a complete launch countdown followed by a seven-minute full firing of the core stage’s engine, as it would fire on a launch into space.
This video shows the Ariane 6 mobile building opening its doors, the building rolling away to leave the Ariane 6 test model on the launch pad and the seven minutes of firing.
On the launch pad in Kourou, French Guiana, the Ariane 6 test model fired of its Vulcain 2.1 main stage engine for seven minutes. This engine, on a real flight, would work with the boosters to propel the 62-m-tall rocket off Earth and into space. For the test the rocket stayed firmly on the ground, but its engine burnt through 150 000 kg of supercooled liquid oxygen and hydrogen fuel for the duration of a real flight. Not only was the core stage being tested, but all aspects of the launch pad and operations, too, from the delicate procedure of fuelling both the main engine and the orbital stage stacked above it to testing the thermal effects of a launch on mechanical and electrical components.
