A modular fuel nozzle tip for a gas turbine engine includes a body defining one or more fuel conveying passages extending therethrough, an annular cap having a radially inner shoulder surface interfacing with the peripheral end surface of the body to define a plurality of air channels extending through the head portion of the modular fuel nozzle tip. At least two fasteners fasten the annular cap to the body.

Fuel nozzle and method of repair

A method of repairing a modular gas turbine fuel nozzle tip, having a fuel-conveying body and an annular cap fastened to the body by at least two fasteners, includes removing the fasteners, replacing the annular cap with a replacement annular cap, and interconnecting the replacement annular cap and the body using new fasteners.

A combustor heat shield comprises a heat shield member defining at least one opening for receiving a fuel nozzle. A louver is received in the opening. The louver has a flow diverting portion extending radially outwardly from the opening for directing air along the hot side of the heat shield member.

A fan blade retention device includes a collar (13) inserted into a circumferential groove (14) cut into the hub (6) of a turbofan engine. The outward facing groove (14) is positioned aft of the fan blade fixing channel (15). When the fan blade root (11) is completely received within the blade fixing channel (15), the blade root (11) contacts the collar (13) and is prevented from traveling further aft. If the collar 13 is segmented, an annular rear cover plate (19) holds the segmented collar (13) radially within the groove (14).

A method and fixture (10) for assembling compliant seals (30) includes an aligning member (12) having a grooved surface (14) for receiving a plurality of loose bristle elements (16). The bristle elements (16) are received within the grooves (26) and aligned thereby. First and second backing rings (20, 22) sandwich the aligned bristles (16) and are clamped by first and second clamping members (18, 24). The clamped rings (20, 22) and bristle elements (16) are then removed from the aligning member (12) and permanently secured together, forming the finished seal (30).
