Impressive by all means, look how clean it all is after all those years of service

 

How the heck does a person find a job to work with this equipment?

 

Heres a few of the major players...

It's not as much fun as it looks in the pictures.

The big impact gun is fun as long as you have a crane to hold it. I haven't seen this big IR denied yet.

This big integral stuff's days are numbered though, a couple little jets like these took place of 6 pretty large engines with capacity to spare.

 

Funny thing is that the Jets burn about twice the fuel! LOL..

 

They do suck up the fuel but in places like here they take the waste heat and drive a small turbine/generator, puts the efficency ahead of the engines at the end of the day.

I'm sooo glad these things don't have to be put back together.

 

Spectra still hasn't upgraded to the higher firing hardware yet for the LM2500. The TMF casing still hasn't been upgraded. The #5 bearing sump is different than the APL stuff. #5 sump TMF have choking issues? Can show lots of pictures of #5 strut leakage. What does the CDP valve look like?

 

Dog, that jet will push 4 to 6 times the amount of gas. Sorry you recip guys are all the same.

 

Why are you asking about the CDP valve? Is there a known issue? I'd imagine given the light load they have the conditions at the end of the HPC would be fine.

There does seem to be an issue with the "elk horns" busting off from time to time. Have you heard about a fix for that from GE?

They can't upgrade the HP they only bought so much HP from Pignone. If they start putting to much HP to the centrif. it will void the warranty agreement. I think they are only running on two fuel rings as it is.

 

The jet replacing that 7000 hp engine is prob 25,000 hp. Hp/MMSCFD isn't that different.. Geeze, turbine guys...

 

There are three fuel rings for the DLE engines, A B C fuel rings. I forgot last night that they are running at a lower firing temp. As for the elk horns failures, the new ones are worse than the older ones. The #5 strut oil sump will pull out over time. The cast TMF was suppose to fix that issue, but doesn't. Can't remember off the top of my head if they limit at a T5 temp of 1525 deg's F. APL runs at 1540 deg's F. Big power increase. Base power for a LM2500DLE 1540 engine is 24370HP at sea level. Its an old Navy engine. The US Navy has tons of them. Was designed back in the 60's. The areo equal is the CFM56

As for the MMSCF vs HP, centrifical compressors are more efficent at higher volumes than a recip compressor. A recip handles the low volume, high pressure ratio better, and is more efficent at that point.

 

I will take that Mike.. No valve loss to deal with even though VE's creast 90% on the Recip.. I bow down to the Centrif...LOL..

 

The centrifugal compressor are slowly getting to the 90% eff mark, most of those are axial inlet compressors. Probably the best that I've tested is around 87% range at around 1.6MMSCFD.

Spectra run compressor PCL802 housing casings, more higher volumes castings (more velocity). APL runs PCL603 housing castings, their stuff is higher pressure, lower volume (less velocity, less friction losses).

 

What would you rather stand beside, a Clark detonating or a roundy round surge?

 

I know how to handle the detonation, that doesn't scare me. So that's not fair.
