Title (EN) NON-AXIALLY SYMMETRIC TRANSITION DUCTS FOR COMBUSTORS
(FR) CONDUITS DE TRANSITION SANS SYMÉTRIE AXIALE POUR CHAMBRES DE COMBUSTION
Abstract:
(EN) A combustor transition duct (110) comprising a main duct portion (113) having a primary opening and a secondary opening, wherein a first axis extends from a center of the primary opening to the secondary opening; an extension flange (115) connected to the main duct portion (113), wherein the main duct portion (113) and the extension flange (115) form a trailing edge (120); and wherein the main duct portion is non-symmetrical along an entire length of the first axis. The non-axially symmetric main duct portion (113) provides improved aerodynamics, heat load, structural strength and engine compactness.
(FR) L'invention concerne un conduit de transition de chambre de combustion (110) comprenant une partie de conduit principale (113) comportant une ouverture principale et une ouverture secondaire, où un premier axe part d'un centre de l'ouverture principale jusqu'à l'ouverture secondaire; une bride d'extension (115) reliée à la partie de conduit principale (113), où la partie de conduit principale (113) et la bride d'extension (115) forment un bord de fuite (120); et où la partie de conduit principale n'est pas symétrique le long d'une longueur complète du premier axe. La partie de conduit principale sans symétrie axiale (113) offre des améliorations d'aérodynamique, de charge calorifique, de résistance de structure et d'encombrement de moteur.
