FUEL AIR MIXER FOR A RADIAL DOME IN A GAS TURBINE ENGINE COMBUSTOR

摘要

A fuel air mixer (46) for a gas turbine engine combustor having a longitudinal axis therethrough, wherein the fuel air mixer is configured for use in a dome oriented substantially radial to the longitudinal axis. The fuel air mixer includes a fuel injection assembly (92) having a first end, a second end, a fuel passage extending therethrough, and a flange portion having a plurality of spaced openings formed therein which extends from the first end. The fuel air mixer also includes a mixer assembly (94) having a first end (122), a second end (124), a cavity (126) formed in a central portion thereof, and a flange portion (136) having a plurality of spaced openings (137) formed therein which extends from the first end. The mixer assembly is configured to receive the fuel injection assembly in the cavity so that the fuel injection assembly and the mixer assembly are able to be connected to an outer casing of the combustor by means of the respective flange portions.
