This timelapse video shows the hot firing model of the Ariane 6 upper stage being installed on the P5.2 test stand at the DLR German Aerospace Center in Lampoldshausen, Germany on 16 February 2021.

After arrival from the ArianeGroup facilities in Bremen, this 5.4 m-diameter upper stage was hoisted out of its container, tilted vertical and installed on the test stand.

Tests will simulate all aspects of flight including stage preparation such as fuelling with liquid oxygen and liquid hydrogen, and draining its tanks.

Data will be gathered on non-propulsive ballistic phases, tank pressurisation to increase performance, Vinci engine reignitions, exhaust nozzle manoeuvres, ending with passivation where all remaining internal energy is removed. Tests will typically last about 18 hours each.
