Abstract
A component for a gas turbine engine includes at least one cooled surface configured to contact a cooling flow, the at least one cooled surface has a base surface and a plurality of cooling nubs disposed about the base surface. The plurality of cooling nubs are distributed about the base surface in a mixed pattern.
Claims10
A component for a gas turbine engine comprising:
- at least one cooled surface configured to contact a cooling flow, the at least one cooled surface being recessed relative to one or more adjacent surfaces;
- the at least one cooled surface having a base surface and a plurality of cooling nubs disposed about the base surface, each cooling nub in the plurality of cooling nubs being an extension of the at least one cooled surface and protruding outward from the at least one cooled surface;
- the plurality of cooling nubs are distributed about said base surface in a mixed pattern, wherein the mixed pattern includes a first set of cooling nubs and a second set of cooling nubs, each cooling nub in the second set of cooling nubs being larger than each cooling nub in the first set of cooling nubs, and wherein the cooling nubs in the first set of cooling nubs are positioned closer to an edge of the at least one cooled surface than the cooling nubs in the second set of cooling nubs;
- and
- wherein said mixed pattern is defined at least in part by each cooling nub including a plurality of distances defined between the cooling nub and each other cooling nub adjacent to the cooling nub, and the plurality of distances is non-uniform.

A gas turbine engine comprising:
- a compressor section;
- a combustor section fluidly connected to the compressor section;
- a turbine section fluidly connected to the combustor section;
- at least one convectively cooled component within said gas turbine engine, the at least one convectively cooled component including at least one cooled surface configured to contact a cooling flow, the at least one cooled surface including a plurality of cooling nubs arranged in a mixed pattern and being recessed relative to one or more adjacent surfaces, each cooling nub in the plurality of cooling nubs being an extension of the at least one cooled surface and protruding outward from the at least one cooled surface and the mixed pattern includes a first set of cooling nubs and a second set of cooling nubs, each cooling nub in the second set of cooling nubs being larger than each cooling nub in the first set of cooling nubs, and wherein the cooling nubs in the first set of cooling nubs are positioned closer to an edge of the at least one cooled surface than the cooling nubs in the second set of cooling nubs;
- and
- wherein said mixed pattern is defined at least in part by each cooling nub including a plurality of distances defined between the cooling nub and each other cooling nub adjacent to the cooling nub, and the plurality of distances is non-uniform.
