Abstract

Une double paroi (2) pour chambre de combustion de turbine à gaz d’aéronef comportant une paroi interne (21) configurée pour être en contact avec la réaction de combustion et une paroi externe (22), écartée de la paroi interne (21), comportant une pluralité d’orifices (3) de manière à permettre la circulation de flux d’air de refroidissement (F), extérieurs à la paroi externe (22), qui viennent refroidir la paroi interne (21), la paroi interne (21) étant exempte de perforation de manière à interdire toute circulation d’un flux d’air de refroidissement (F) vers le centre de la chambre de combustion, la paroi interne (21) comportant une pluralité d’organes en saillie (4) vers la paroi externe (22), chaque organe en saillie (4) s’étendant dans un orifice (3) de manière à définir une section de passage calibrée entre l’organe en saillie (4) et l’orifice (3) pour le passage d’un flux d’air de refroidissement (F).
