Abstract
In a gas turbine liner, air metering passages are placed in dimples in a first liner sheet to provide an air chamber. A second liner sheet contains an air outlet for each dimple. The second sheet masks the metering passage and a portion of the dimple. A coating is applied to the second sheet and extends into the dimple but does not cover the metering passage.
