Turbojet engine conversion

This is the J79 engine featured in " Inside an afterburner ". Walter has converted it into an LM1500 , an industrial engine rated at over 15,000 Hp. The last time this engine ran it was in an F104 Starfighter. It will now lead a long and pampered life as a stationary ground power unit.
It racked up 2500 hours as a flight engine. It will likely run for over 100,000 hours as an LM1500.

My friend and I are having an argument trying to figure out the output capacity of this machine in terms of work.

He's convinced that the 15,000 HP rating is one of mechanical energy and that friction along with other factors will decrease the yield of this generator. I, however, believe that in being converted from J79 fighter engine to a LM1500 generator, the HP rating is directly related to electrical output.

So which is it?

@Hijynx427 That's the Hp you get out of it when you use a power turbine to extract energy from the exhaust stream. As for the power output of the engine itself... well, it's more than that.

@AgentJayZ So this engine will deliver *roughly* 15 MW of electrical power?

[AgentJayZ]

@AGrandt At 746W per Hp, and considering the efficiency of the power turbine it's hooked up to, and the generator that that's hooked up to... you'll get about 9MW of power flowing down the lines at full throttle.

Fascinating to see the inlet guide vanes altering with the throttle towrds the end of the video. Amazing to hear how long it will run! Will it do short bursts of power to top up the supply or what? Thanks again for such interesting information and video.

[AgentJayZ]

@102trafalgar Well, the systems of pipelines and reservoirs that these engines are used in are so large that a "short burst of power" could be described as running an extra engine for a week or so.

It's usually only economical to run these engines at their rated output: aka full power.

Ha Yeah I see you operating the huffer!

[SEXXYBEASTnotryan]

it almost sounds like there are two engines running simultaneously

very nice unit, great conversion!
