NON-AXIALLY SYMMETRIC TRANSITION DUCTS FOR COMBUSTORS

摘要

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.
