An improved swirler assembly prevents flow separation in the diffuser secn. An annular swirling layer of air surrounds a linear jet with mixing occurring between these air flows prior to the diffuser section. A center tube through the swirler section provides the linear jet which mixes with the swirler flow in a mixing area prior to the diffuser section.

Swirler assembly for a vorbix augmentor

A mixed flow turbofan engine in which a portion of the core engine exhaust gases are passed into a pilot zone chamber where fuel is added thereto for vaporization therewith and wherein the fan air is passed over a series of vortex generators so that the vortex flow fan air and the vaporized fuel mixture will mix and combust rapidly in an augmentation combustion chamber.

Turbofan engine with augmented combustion chamber using vorbix principle

A low emission combustion chamber in which vitiated products of combustion from a pilot burner are caused to swirl about the combustion chamber axis before fuel droplets are introduced into the vitiated, swirling combustion products for flash vaporization therein to produce a vaporized, swirling, vitiated fuel-air mixture so as to effect ignition lag until swirling combustion air can be mixed with the swirling mixture to molecularly premix the fuel and air and increase its oxygen content to reduce the ignition lag to effect autoignition at an equivalence ratio less than 1 so as to effect high-rate, lean burning in the primary combustion chamber.
