Verfahren und Vorrichtung zur Erhöhung der Wärmeübertragung in einer Brennkammer

摘要

A combustor (16) for a gas turbine engine (10) includes a deflector assembly (40) that enhances heat transfer from the combustor and minimizes low cycle fatigue stresses induced within the combustor. The deflector assembly includes a plurality of deflectors (42) secured to a spectacle plate (44). Each deflector has tapered edges (102, 104) and includes a plurality of cylindrical projections (140) extending outward from the deflector to facilitate heat transfer. The projections include rounded edges (178) and are arranged in a high density pattern (142). The deflector is coated with a thermal barrier coating and a bondcoat to minimize exposure to hot combustion gases or flame radiation.
