Abstract
A heat shield for a combustor of a gas turbine engine has a heat shield adapted to be mounted to a combustor wall with a back face of the heat shield in spaced-apart facing relationship with an inner surface of the combustor wall to define an air space. Concentric rails extend from the back face of the heat shield across the air space surrounding a nozzle opening in the heat shield. Effusion holes are provided between the concentric rails and extend between the back and front faces. Fins may be placed between the effusion holes.
