Abstract
A turbofan engine augmenter includes an exhaust casing and a combustion liner therein which define therebetween a cooling duct for receiving bypass air. A diffusion liner adjoins the combustion liner and defines with the casing an outer inlet for receiving the bypass air, and a radially inner inlet for receiving core gases. A ring flameholder includes an aft facing radial wall adjoining the diffusion liner, and an integral axial wall adjoining the combustion liner. A plurality of circumferentially spaced apart radial flameholders extend inwardly from the casing and through the diffusion liner forward of the ring flameholder, and each includes a first fuel spraybar for injecting fuel into the core gases. A mixer defined by a plurality of injector chutes extends radially inwardly through the diffusion liner, with the chutes being spaced between respective pairs of the radial flameholders. Each injector chute includes an inlet for receiving the bypass air, and an outlet at an opposite end for injecting the bypass air into the core gases.
