Abstract
A gas turbine engine combustor is provided with a semi-spherical upstream wall constituted by two correspondingly shaped skins which are spaced apart by pedestals attached to one of the skins to define a space between them. Cooling air is progressively metered into to space through apertures in the first upstream skin to provide effective cooling of the second downstream skin. The cooling air is exhausted from the space through an outlet defined by the first skin and the periphery of the second skin to provide film coating of the upstream end of the combustor side wall.
