ABSTRACT:
A method for distributing fuel within a gas turbine engine is provided. An augmentor is provided which includes a plurality of vanes. Each vane includes a pair of side walls, an aft wall, and a plurality of fuel apertures and pressurized gas apertures extending through the side walls. At least one of the pressurized gas apertures is positioned adjacent and forward of all fuel apertures at a particular position. At least one fuel distributor is provided in each vane. Fuel admitted into the fuel distributors flows into the core gas path in a direction substantially perpendicular to the core gas path. Gas admitted into the vanes at a pressure higher than that of the core gas flow, flows a distance into the core gas path in a direction substantially perpendicular to the core gas path. Fuel is selectively admitted into the fuel distributors when the augmentor is enabled. Pressurized gas entering the core gas path forward of the fuel creates a low velocity wake that enables the fuel to distribute circumferentially.
