摘要： A combustor includes outer and inner liners joined together by a dome to define a combustion chamber. A row of air swirlers is mounted in the dome and includes corresponding main fuel injectors for producing corresponding fuel and air mixtures. Pilot fuel injectors fewer in number than the main injectors are mounted in the dome between corresponding ones of the swirlers. Staged fuel injection from the pilot and main injectors is used for starting the combustor during operation.

摘要： A combustor baffle includes an annular splashplate having a center mounting tube therein for receiving a carbureted stream. A semi-ferrule is offset both laterally and transversely from the tube, and is open laterally outwardly therefrom. The semi-ferrule cooperates with an adjoining semi-ferrule for defining a port in which a pilot injector or igniter may be mounted.

摘要： A gas turbine engine combustor carburetor includes forward and aft air swirlers. The aft swirler has a septum defining a primary venturi and a plurality of circumferentially spaced aft swirl vanes. The forward swirler has a plurality of circumferentially spaced forward swirl vanes extending forwardly from a flat annular radial flange of the forward swirler, an annular wall extending forwardly from a forward face of the septum and radially bounding an annular recess on the forward face, and the radial flange slidably retained within the annular recess and against the septum by a flat retainer attached to the annular wall of the septum. The flat retainer may be produced by stamping. An anti-rotation tab on the radial flange of the forward swirler extends radially through a corresponding notch in the annular wall.
