Abstract
A combustor heat shield has a heat shield body having a first surface configured to face a combustor shell and an opposed second surface configured to face towards the combustion gases in the combustion chamber. A dilution or igniter hole is defined in the heat shield body. An array of circumferentially spaced-apart cooling holes is provided around the at least one dilution or igniter hole. The cooling holes are oriented to locally deliver a swirl of cooling air around an axis of the dilution or igniter hole. The cooling holes are angled relative to the heat shield body and extend from an inlet on the first surface to an outlet on the second surface. The outlet is positioned closer to a perimeter of the dilution or igniter hole than the inlet.
