SINGLE SKIN COMBUSTOR HEAT TRANSFER AUGMENTERS

摘要

A combustor for a gas turbine engine comprises a single skin liner defining a combustion chamber. The single skin liner has an inner surface facing the combustion chamber and an outer surface exposed to a coolant flow discharged in a plenum extending from the outer surface of the single skin liner to the engine casing. Cooling holes extend through the single skin liner. Open flow guiding channels are provided on the outer surface of the single skin liner, the open flow guiding channels being uncovered and aligned with the flow of air over the outer surface of the single skin liner.

1. A single skin combustor for a gas turbine engine, the single skin combustor comprising: a single skin liner defining a combustion chamber, the single skin liner having an inner surface exposed to the combustion chamber and an outer surface exposed to an open-channel flow of air in a plenum circumscribed by a gas generator case of the gas turbine engine, the outer surface of the single skin liner being an outermost surface of the combustor, cooling holes extending through the single skin liner, and open flow guiding channels provided on the outer surface of the single skin liner, the open flow guiding channels being uncovered and aligned with the flow of air over the outer surface of the single skin liner.
