A combustion chamber louver assembly includes an aft louver having a forward panelthat extends axially from a louver leading edgeto a corner, and a forward louver joined to the forward panel of the aft louver. A lipdefined by a portion of the forward louver that extends axially past the corner to a louver trailing edgeincludes circumferentially distributed trailing edge slotsextending forwardly from the trailing edge a nominal distance equal to about 88% to 95% of the length L of the lip.

Crack resistant combustor

A fuel nozzle for a gas turbine engine includes an engine mount end and a discharge end that discharges an air/fuel mixture into a combustion chamber. The fuel nozzle includes a centerbody and a heat shield. The heat shield is fixed to the centerbody at a mid-mount position that is centrally located between first and second ends of the heat shield to allow the heat shield to remain thermally isolated from radially adjacent components to reduce the adverse effects of thermal stresses.
