Abstract

L'invention concerne une chambre de combustion de moteur à turbine à gaz équipée d'une prise annulaire d'air réfrigérant montée entre la culasse 14 et la paroi latérale cylindrique 16 de la chambre. Cette prise d'air annulaire 18 est constituée par deux cercles ou anneaux 20 et 22, réunis angulairement en 28, percés de rangées de passages d'air 24 et 26, respectivement, les premiers étant inclinés de façon à diriger l'air sur la face interne de la culasse 14 tandis que les seconds le sont de façon à le diriger sur celle de la paroi latérale 16, l'ensemble étant recouvert extérieurement par un auvent annulaire 19 captant l'air provenant du compresseur et le forçant à passer par les passages en question pour pénétrer dans la chambre de combustion. Le dispositif permet une répartition avantageuse de l'air réfrigérant entre les parties avant et arrière de la chambre de combustion.
