摘要：Disclosed is a fuel nozzle guide for use in gas turbine engines. The nozzle guide comprising an annular bushing sized for receiving a fuel nozzle, wherein the bushing has a first end and a second end, the first end being connected to a nozzle guide retainer. A flange extends radially from the second end of the bushing, wherein the flange has a proximal portion spaced proximal to the bushing, and a distal portion spaced distal from the bushing. The distal portion of the flange extends substantially parallel to a combustion chamber bulkhead heat shield. A plurality of radially extending ribs are disposed about the distal portion of the flange, each of the ribs having leading ends and trailing ends, wherein the trailing ends are arcuate in shape, thereby facilitating a reduction in film cooling air vortices as film cooling air passes between the ribs, and thereby assisting in the cooling of the bulkhead heat shield.
