Abstract
A pilot nozzle heat shield includes a body having a first end for receiving a pilot nozzle and a second end including a flow tip. The body includes a plurality of internal turbulators circumferentially disposed about the internal peripheral surface of the body. The flow tip includes a proximal periphery and a distal periphery. A plurality of flow ports are circumferentially spaced about the proximal periphery of the flow tip. The flow tip includes a plurality of slots. Each slot extends distally from one of the flow ports to the distal periphery of the flow tip, which defines an aperture. The plurality of slots define a plurality of tangs; each tang is defined between a pair of neighboring slots. A plurality of turbulators can be disposed about the inner peripheral surface of the heat shield body at the tangs.
