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.

An assembly of a bulkhead 48 and fuel nozzle guide 62 for a fuel nozzle 46 disposed in a combustion chamber 24 is disclosed. Various construction details which provide for positively cooling components of the assembly are developed. In one detailed embodiment, the nozzle fuel guide is spaced from the bulkhead to form an annular gap G.sub.1 which is divided by a heat shield 72 into annular orifices 108, 112 for supplying to cooling air passages 126, 128 bounded by the heat shield 72.

A fish hook for carrying live bait fish is disclosed. The hook includes a curved, primary shaft that is attached at an upper end to a fishing line. A barbed, pointed section is connected to a lower end of the primary shaft. A secondary shaft is flexibly interconnected to and extends from the primary shaft and is insertible through the mouth and gill of a live bait fish. A clasp selectively interconnects the primary shaft and a distal portion of the secondary shaft to restrict removal of secondary shaft from the live bait fish.

A fuel nozzle assembly 32 for a gas turbine engine 10 is disclosed. Various construction details relating to a heat shield 92 are developed. In one embodiment, the heat shield is attached to only a radial surface 96 on the assembly and is free to grow axially from the radial surface of attachment.

Fuel nozzle assembly and method for making the assembly

A fuel nozzle assembly 32 which extends into a flow path 18 for working medium gases is disclosed. Various construction details which decrease the amount of heat transfer to the fuel are developed. The assembly includes an external heat shield 50 and an internal heat shield 98 which provide longitudinally overlapping insulating gaps 52, 102 between the fuel and the hot working medium gases. In particular, the insulating gap 52 extends to the inlet 94 of the fuel nozzle support.
