What are the components of the afterburner and what do they do?
Answer: Four components: Spray bars, Flame holders, Screech liner, and Variable Exhaust Nozzle. Spray bars inject fuel into the afterburner; flame holders create turbulent eddies to mix fuel and air. The Screech liner is a shock absorber that prevents vibrations and turbulence, and the variable exhaust nozzle increases air's exit velocity.
