Update to this one: The engine was tested yesterday.

http://www.dlr.de/dlr/en/desktopdefa.../gallery/29560

The article also describes some of the other changes between Vulcain 2 and Vulcain 2.1, especially the 3D printed gas generator and the simplified nozzle structure. This test did still use internal pyrotechnical igniters as in the Vulcain 2, later tests will switch to use propane gas supplied from the test stand as ignition fuel.

Thought we had an Ariane 6 thread? Can't find it.

This has been an intense year for Ariane 6 development, with progress boosted across Europe: plants are manufacturing new parts using novel methods, all engines have been tested, and the construction of launch facilities is well underway.

We do have an Ariane 6 engine news thread, and another short thread on Ariane 6.

I don't mind merging them, if everyone is fine with it.

Here's the full search result: https://www.orbiter-forum.com/search...=2109213&pp=25

Today, the DLR German Aerospace Center in Lampoldshausen inaugurated a new test facility that simulates launch for the complete Ariane 6 upper stage.
The Lampoldshausen centre makes a key contribution to Europe’s progress in space propulsion and already tests the Ariane 6’s Vulcain 2.1, and Vinci rocket engines. Other rocket engines tested here include the upper-stage expander cycle demonstrator ETID, and recently a 3D-printed thrust chamber designed for storable-propellants, both developed within ESA’s Future Launchers Preparatory Programme.

To be more specific: They updated P8 to P8.3. P8 was originally used for testing LH2/LOX engines for Ariane, and now got upgraded to support more powerful engines.

From the permission for the new test stand of last summer, its possible to deduce what kind of engines will be tested there:

The maximum permitted "Feuerungswärmeleistung" according to German emission law is 510 MW, sadly its a German legal term and hard to translate into English. Its the accumulated lower heating value of the hydrogen fuel burned per second. Which allows a bit of cheating since LH2/LOX results in water vapor and the vaporization energy of the water vapor produced can be added to the limit to calculate how much hydrogen can be burned every second... but how this is exactly calculated exceeds my knowledge:

I suspect, you can subtract about 2.2 MJ/kg from the 199 MJ/kg LHV of hydrogen to get the hydrogen mass flow allowed: 4 kg/s, total mass flow is thus 5.7 times higher, about 25 kg/s. That means about 110 kN of thrust in that case. (I likely got this wrong, since the Vinci engine has 180 kN... again, German laws are complex there)

Will be tested twice between 6:00 and 22:00 on 2.5 days in a week, for maximal 80 second of burn for large engines and maximal 3 hours of flare stack operation during each test...

The spark igniters were to simply prevent hydrogen build-up on the pad during start up. They did not ignite the engines. Each SSME had two redundant augmented spark igniters (essentially spark plugs) each for the main chamber and preburners.

At Europe’s Spaceport the Ariane 6 mobile gantry, a 90 metre-high metallic structure built to house Ariane 6 underwent a 97 m roll-out test last week to mimic prelaunch.
When fully equipped, this mobile gantry will weigh 8200 tonnes – more than a thousand tonnes heavier than France's Eiffel Tower. Its platforms provide access to the launch vehicle for integration on the launch pad. It protects Ariane 6 until its doors are opened and it is retracted about five hours before the launch.

Description
Things are shaping up at Europe's Spaceport in French Guiana in preparation for Ariane 6. Take a tour of the launch complex and its various facilities. Recent tests have used mock-ups of the P120C boosters to trial how they will be transported. See them on the launch pad, and get a sense of scale for Ariane 6.

Ariane 6, Europe's next-generation launch vehicle, has passed another key development milestone. Its Vulcain 2.1 liquid-fuelled engine has now completed its qualification testing, which means combined tests can now begin.
