Cavity swirl fuel injector for an augmentor section of a gas turbine engine

An augmentor section for a gas turbine engine comprising:

• a tubular case;
• a center body within the tubular case;
• an augmentor vane extending radially through an exhaust gas path of the gas turbine engine from the tubular case to the center body;
• a spraybar mounted within said augmentor vane;
• and
• a fuel injector mounted to said spraybar to communicate through said augmentor vane, wherein said fuel injector is configured to generate counter-rotating vortices;
• wherein the fuel injector comprises a first wall and a bottom wall transverse and perpendicular to the first wall, the first wall and the bottom wall at least partially form a fuel injector cavity, a first airflow passage and a second airflow passage extend through said first wall, and a fuel injection aperture extends through said bottom wall.
