Heat shield panels

摘要

The present invention relates to heat shield panels (20') or liners to be used in combustors for gas turbine engines. The heat shield panels (20') each comprise a hot side and a cold side and at least one isolated cooling chamber (70') on the cold side. Each cooling chamber has a plurality of cooling film holes (32) for allowing a coolant, such as air, to flow from the cold side to the hot side. A rear boundary wall of chamber (70') is formed by arrays (106,112) of pins.
