US Patent Application No: 12085279

Gas turbine combustor with enhanced cooling features

---

Abstract

---

A combustor for a gas turbine engine includes a combustor liner with a wall defining a combustion chamber. The wall has an inner surface facing the combustion chamber and an outer surface across the wall from the inner surface. Fins are disposed on the outer surface. The wall defines air admission holes that extend through the wall from the outer surface to the inner surface. The wall also defines film cooling holes that extend through the wall from the outer surface to the inner surface. The fins are disposed in areas of the outer surface between the film cooling holes and the air admission holes to cool areas that would otherwise result in hot spots.
