Turbojet Tuesday
On our first cold day of the season, we can warm up in ( near! ) the jet blast of an afterburning turbojet engine.
GE J79 J1-E
Idle rpm 5000
Max rpm 7685
Max dry thrust 11,500 lbs consuming about 40 gallons per minute of Jet A.
Max reheat thrust 18,300 lbs using about 90 gallons per minute of fuel.
Spelled out, so you know it's not a typo, and yes... per minute, not per hour.
A gallon and a half per second.
There are two fuel pumps. The one for the afterburner takes one hundred seventy five horsepower to function.
