Testing a GE J79 with afterburner

A newly rebuilt engine from a supersonic fighter is put to the test at the S&S / Maddex test cell. After some run-ups from idle to full military power, the afterburner is engaged, resulting in some extreme camera abuse...

How many pound of fuel does that gas turbine burn up on after burner.

what is the rate of consumption,when at idle.

Do you guys use k-1 or JP-5.

Very surprised the camera didnt shake apart.

Do you guys have a load cell on the cradle to measure the force out put.

yes it was dirty ENGINEERING PORN I feel so dirty.

@arbitor1701 Idle, a couple gallons per min ( we didn't measure idle)

Full military power 37 gal per min. The bigger Canadian gallons !

Afterburner uses 50 gpm, so a total of 87 gpm in full AB.

@DiamondPilotDan Only a fraction of the oxygen passing through the engine is consumed even at full military power, so there is plenty left over to feed the afterburner. If the engine burned most of the oxygen passing through it, it would get so hot that the interior would melt. Because an afterburner is at the tail end of the engine, the engine can get some more power from that leftover oxygen without heating up its interior too much.
