Turbulated combustor aft-end liner assembly and related cooling method
In a combustor for a turbine a cover sleeve (140) is disposed between the aft end portion of the combustor liner (118) and a resilient seal structure (38) to define an air flow passage therebetween. The cover sleeve (140) has at a forward end thereof a plurality of air inlet feed holes (146) for dir...

| description | In a combustor for a turbine a cover sleeve (140) is disposed between the aft end portion of the combustor liner (118) and a resilient seal structure (38) to define an air flow passage therebetween. The cover sleeve (140) has at a forward end thereof a plurality of air inlet feed holes (146) for directing cooling air into the air flow passage. A radially outer surface of the combustor liner aft end portion defining the air flow passage includes a plurality of turbulators (52) projecting towards but spaced from the cover sleeve (140) and a plurality of supports (144) extending to and engaging the cover sleeve to space the cover sleeve from the turbulators to define the air flow passage. |
