Updates Ariane 6 Updates

Engine still gimbaling after shutdown.

Full 470 second burn achieved.

EDIT: Looked initially as if the engine shutdown after exactly seven minutes, but its possibily just the throttling at the end of the burn that caused the nozzle temperature to drop (red glowing instead of white glowing)

Test ended with full core stage propellant consumption.

"Only" did about 7:10 of the advertised 8 minutes.

470 seconds was the actual burn time planned, 7:50. That fits to the point the nozzle suddenly cooled down and lost its red glow.

Went back in the stream and the shutdown is visible at 7 minutes.... maybe there is a glitch in the Matrix?

When the camera went back to the engine view just after 7 minutes, it looked like free H2 burning, just like the SSME had after shutdown.

Again, the regenerative cooled nozzle kept on glowing until 7:50, while it cooled down slightly from 7:00 on to 7:10 (change in glow color). I think it was not a full shutdown, but a thrust reduction.

According to CNES Guiana Space Center range operations director Thierry Vallee, the test lasted for 426 seconds. Despite ending 44 seconds early, CNES, ESA and ArianeGroup have all stated that the test appeared to have been completed successfully.

ESA has successfully completed a key Ariane 6 development milestone with the successful completion of a long-duration hot fire test.

So, I was wrong and you were right. The test really did not reach the full duration.
