Claim:
1. A combustor heat shield assembly comprising a circumferential array of heat shield panels individually mounted to an inner surface of a combustor shell, each heat shield panel having opposed front and back faces, the back face facing the inner surface of the combustor shell and being spaced therefrom to define an air gap, the front and back faces having a perimeter including opposed lateral edges radially extending between opposed circumferentially extending edges, wherein the lateral edges of adjacent heat shield panels have complementary non-linear profiles, and wherein the opposed lateral edges of each heat shield panel are asymmetric about a central radial plane (A) of the heat shield panel, wherein the central radial plane extends radially from and along a longitudinal axis of an engine, wherein each lateral edge extends along a curved line, the curved line extending continuously from one circumferentially extending edge to the other circumferentially extending edge.
