Vorbix augmenter configuration with diffuser and vorbix swirler

摘要

An augmenter construction for fan engines in which the fan air and the engine gas are distributed through transition ducts terminating in vortex generators and the fuel rich pilot gas discharges around these vortex generators to mix with the vortices for improved combustion. The transition tubes have diffuser sections extending from the vortex generators and these sections have rectangular or multisided terminal ends.
