If I were still in Germany id take you on a tour of a real JET ENGINE shop , I was the Flight Chief of the first all new Jet Engine overhaul facility it the entire USAF in 1992. Spangdahlem AB near Treir , about four miles from Bitburg. We completed overhauls and repairs to F 16 ,engines, two...

YES, thermocouple , in jet engines they tend to be of two different types Single pole and dipole or siamese on a T56 _15 turboshaft jet engine for example their used to measure TIT. Not anatomy but Turbine Inlet Temperture and they are dipole (two circuits) (Siamese) one is used for the...

I use the term "EGT" Exhaust Gas temperature and "Pyrometer" Indicated Pyrometer Temperture universally , they are roughly the same The GTCP uses a pyrometer , not an EGT probe but its a basic alumel chromel , dissimilar metal temperature indicating circuit . In jet engines different engines...

DONT MISUNDERSTAND . and do anything silly, but if you want to test the systems and light it off IF YOU ARE SURE you have positive oil pressure and have a bad switch , just wire around it with a shunt , provide the signal, it will likely fire up and if so your on two step 2 , EMERGENCY SHUT...

Positive indicated oil pressure IS needed to complete light off, having said that , on your filter , there are two types the old style was a screen and spacer type that was cleanable, a series of mesh screens one on top of the other in sequence, you stripped them down chucked them in the ultra...

Yes thank you. It had been a long day. And yes 7808 causes cancer. Used to swim in the stuff we all regularly sucked the stuff up the Joap ( joint Oil Anylisis Program ) sample tubes for oil wear trend analysis as well and spit it out. Mil-l -29515 sticks in my mind as the non synthetic turbine...

Two more useful points ensure you have s fire extinguisher hand. If you have a post shut down combustion can fire. Do not discharge extinguisher intake or exhaust. Kill the fuel and motor the turbine over until the fire is extinguished. Worst result is you may fry starter. If you hit it with a...

The micro switch is a service able unit. Usually a little mIL-L-7808 turbine engine oil will free it up. Don’t get it on your skin is is a known cancer causing agent , lol glad I could help. Usually the first thing to look at is the micro switches I’ll still see if he can find the data

Guyfang is correct. They may help you and just might have an old TO around. Historically they replied to official calls. We were billed at the wing level at an hourly rate , by the end of Viet - Nam garret had no more GTCP tech reps at any AFB s for that unit I never saw it used in any...

The start relays at K16 and k17. Near the fuel control test ports also know as the salt and pepper relays your looking for power thru the relays. They control the start of the start cycle. Once rotating the Three speed switch kicks in around 25 percent rpm opens fuel solinoid , supplies...

We referedto the as APUs as well Auxillery power Units , and tiny turbines , The turbing is easily removed, Theses were manufactured when every thing aircraft related was built and maintained the same as your assigned aircraft , In the early days when ever we defueled a jet,could have been...

I retired in 1994, was a small gas turbine shop Chief in the mid eighties doing repair on these, Seems to me the T.O. number was 2G-GTCP-85-70a , it breaks down as Aircraft , Ground support, Gas Turbine Compressor Powerplant, 85- 70 a model. Air Research made or remanufactured most of these.

May you have been NAVY , In the Air Force we used HUNDREDS OF THEM , most had the 71a gas turbine . We called them Plooshes for short, because when you stretched the hose out and loaded air down the line to flush it PRIOR to attaching it to an aircraft it would make a Plooshe sound. The engines...
