The F-35 can add a second burn behind its engine’s turbines. Follow the air through the fan, compressor and main combustor, then see how fresh afterburner fuel adds energy before the exhaust leaves the nozzle.
The turbine extracts energy to drive the fan and compressor. When the afterburner is engaged, extra fuel burns downstream; it is a second combustion location, not the same fuel being burned twice.
