Abstract
A combustor liner () for a gas turbine engine combustor () comprises an inner wall (), an outer wall (), a flow channel () formed there between, and an end-capping ring (). The end-capping ring () is sealingly attached to the downstream end of the inner wall (). In operation air passes within the end-capping ring (), into the flow channel (), and through holes () disposed in the inner wall (). In some embodiments, an end-capping ring variation, a flow-diverting ring () comprises a plurality of holes () that, during gas turbine engine operation, may additionally dispense a flow of cooling air. One or more surfaces may be coated with a thermal barrier coating () to provide additional protection from thermal damage.
