Abstract
A cooling liner having a liner hot sheet formed as a relatively thick iso-grid structure having iso-grid ribs, which extend from a surface between the ribs. A multitude of metering sheets are mounted directly to the liner hot sheet surface. Each metering sheet is mounted to the iso-grid to define a multitude of discrete chambers. A seal is located in a pattern along a subset of the iso-grid ribs to further segregate the surface covered by each metering sheet into a further number of discrete subchambers. Each metering sheet includes a multitude of metering sheet apertures and the surface between the iso-grid ribs of the liner hot sheet include a multitude of hot sheet apertures. By varying the ratio between the number of metering sheet apertures and the number of hot sheet apertures, the pressure in each chamber is defined to efficiently maintain the minimum desired pressure ratio across the hot sheet without undue wastage of cooling airflow.
