Ariane-6’s core stage completes full 7 minute engine test
Engineers yesterday successfully completed a two-hour dress rehearsal countdown and fueling of an Ariane-6 first stage followed by a full seven minute engine burn, simulating what that stage would do during a launch.
The test took place on Ariane-6’s launchpad in French Guiana.
The November 23 test sequence was run the same way as the previous ones, with a launch sequence and final countdown representative of a launch, including removal of the mobile gantry and filling the launcher’s upper and core stage tanks with liquid hydrogen (-253° Celsius) and liquid oxygen (-183° Celsius). The test ended with the ignition of the core stage Vulcain 2.1 engine, followed by more than 7 minutes of stabilized operation covering the entire core stage flight phase. All functional aspects of Ariane 6’s core stage during the flight phase were tested.
According to the European Space Agency, only one more engine test of the Ariane-6’s upper stage remains before the spring launch can be attempted, and that engine test is planned for next month in Germany.
With the retirement of the Ariane-5 rocket in July, Europe has had no large rocket to launch payloads. Originally Ariane-6’s first launches were supposed to be in parallel with Ariane-5’s last launches, but its development is four years behind schedule.
