Title (EN) ACOUSTIC DAMPER
(FR) AMORTISSEUR ACOUSTIQUE
Abstract:
(EN) An apparatus for attenuating acoustic oscillations of a gas flow contained in part by a combustor wall of a gas turbine engine combustor. wherein the combustor includes at least one air/fuel mixer, includes at least one resonating tube with a closed end and an open end and a single cavity between the ends. The tube is located on the combustor wall downstream of the air/fuel mixer.
(FR) L'invention porte sur un appareil pour atténuer des oscillations acoustiques d'un écoulement de gaz contenu en partie par une paroi d'une chambre de combustion d'un moteur à turbine à gaz. La chambre de combustion comprend au moins un mélangeur air/carburant, et au moins un tube résonnant dont une extrémité est fermée et une extrémité est ouverte, et une seule cavité entre les extrémités. Le tube est disposé sur la paroi de la chambre de combustion en aval du mélangeur air/carburant.
