J79 with afterburner at the S&S Turbines open-air test cell in Ft. St. John B.C.
Taken from a Kfir fighter, after it had suffered damage.
The compressor rotor was destroyed by FOD (foreign object debris) ingestion, and was completely replaced.

This is the same engine as that in the F-104, F-4, B-58, and some early F-16s.

The "smoke" you see coming from the engine at full power/afterburner is not smoke, but unburnt fuel. The afterburner in these shots is spraying fuel into the jetpipe, but the igniter in not functioning. What you see is 50 gallons per minute of jet fuel being blown out the nozzle.

Later shots show the afterburner functioning.

Comments are welcome, and questions will be answered
