ABSTRACT:
In a turbofan jet engine, having a circumferentially rotatable mixer segment capable of orienting the afterburner ignitors and flameholders into the path of either the exhaust gases or bypass air, a fuel-air transfer apparatus for capturing, transporting and the releasing of an enriched fuel-air concentration from the fuel spray bars, on the stationary structure of the jet engine, to the afterburner ignitors and flameholders rigidly attached at the rear of the rotatable segment of the mixer. The enriched fuel-air mixture is transported between a location of reliable fuel availability, through a region of highly turbulent gas flow and is thereafter released while still in an enriched concentration immediately upstream of the ignitors and flameholders, facilitating ignition and sustained operation of the afterburner. The transfer of the fuel-air mixture with the exhaust gases in a confining apparatus precludes the necessity for transferring fuel, by flexible attachment or other means, between the stationary jet engine structure and the rotatable segment of the mixer, upon which the ignitors and flameholders are mounted, while insuring an appropriate fuel-air mixture for ignition and operation of the afterburner.
