Acceptance of a key Vulcain 2.1 engine component


Aircrafts and Launchers of tomorrow – Green Aircrafts + 4.0


Innovative design for the Green Aircraft

Customer needs

Acceptance tests, via implementation of hydraulic tests, of the Vulcain 2.1 engine gas generator injection heads, for use on the Ariane 6 launcher and produced using additive manufacturing. The numerous very small-calibre internal cavities of this geometrically complex part must not be clogged or polluted by fine particles found in the water.

Customer benefits

Fluid mechanics expertise, proficiency in digital and experimental techniques, together with multi-disciplinary knowledge, enabled Cetim to set up the hydraulic bench to meet the test requirements and characteristics of the gas generator injection head for the Vulcain 2.1 engine.

Cetim answer

By designing and integrating a filtration system on the hydraulic test bench, Cetim ensured the integrity of the injection head and avoided polluting the numerous small-calibre cavities with particles found in the water used for the tests.

Delivered results

Tests conducted according to applicable protocol on a bench integrating a water filtration system meeting injection head characteristics and its operating parameters. Acceptance of injection head behaviour through flow rate and pressure loss measurements.
