Ariane 5 proceeds as planned


The action plan to bring Arianespace's Ariane 5 heavy-lift launcher back to flight status is proceeding as planned.

In Germany, the third series of Aestus test firings was conducted on August 28 to evaluate the engine's ignition process. This test series went well, and "soft" ignition conditions were reproduced.

Work on modeling the conditions inside Aestus during engine ignition also is moving ahead, with the merging of hydraulic and combustion models now underway.

A first validation of the dynamic model created with data from the initial test firings showed results that were very representative of actual conditions seen during the third test firing series.
