- With a little bit of down time around the hangar while at NASA's Wallops Flight Facility, I saw the opportunity to talk a little bit about the Allison T-56 engine which is the power plant used in the P-3, C-130 and the Super Guppy Transport.
There are a few minor differences between them each (and actually the Super Guppy was fitted with the 501-D22C and water-methanol, but we've since acquired 8, T-56-14s that are being retrofitted to accept the water-methanol system to replace the 501s), and essentially, they are the same engines.
I'm not getting into the weeds too much about the details of these engines, but more so than the average person gets to see with these, so c'mon along & let's see some of the components that make up this efficient, reliable & POWERFUL, 4600 SHP beast of a turboprop power plant!

t56 motors are such a beautiful piece of machinery.
Worked on the P-3C program at NAS Alameda. There is nothing like the sound of those Allison turboprops. Music to my ears.
I am building the 1:10 scale Atlantis model of the Allison T-56. I was an AMS in VP-48 way back in the late seventies, early eighties.
Thanks for the cool walk around. My model won’t be quite as busy as the real thing. I plan on making it look like an instructional or “lobby” model.
Great video. You are spot on...the fuel control on the T-56 is a masterpiece of hydro-mechanical engineering. Now if I could just understand fuel control hysteresis my P-3 knowledge would be complete. Cheers
Pt2 hysteresis or speed rack?
Can confirm the fuel control is magical, lots of fun to work on.
Very cool! Been supporting T-56 Series 3.0, 3.5 and 4 MRO down in San Antone
Oh really? What do you do. Who do you work for? Is it a place that I could come do a video tour? I’m in Dallas. Shoot me an email: unusualattitudesinflight@gmail.com. I’d love to chat with you about it!
Thanks for watching!
Beautiful engine !!
My first AFSC in the Air Force was a 454X0B or 2A6X1B. From 1992-2000 at DMAFB Tucson. 355th CRS... until I cross trained to a 1 alpha 7 door gunner on the HH60 Pavehawks 55th DMAFB.
Appreciate you creating this video! P3 pilot here brushing up on my propulsion system knowledge!
T56 engine fuel system consist of two magical components.the Fuel control unit and the Temperature datum valve or TD valve.
Magical on who you ask, I have been building and calibrating fuel controls and td valves for about two years now, they are truly amazingly advanced pieces of equipment
@@dustinvail8208 the fuel pumps can also be a little interesting on test
You H model guys know your systems lol I don’t know many pilots that can walk through an entire dismantled engine. Really impressive
I knew it already before you said. I know everything about the T56 and nobody knows more than me. Lol
Sweet vid Matt!
Good explanation and introduction, well done!
Thanks man, I appreciate it! Thanks for watching!
Doing my first hot section T56 disassemble today.
That's cool man- good luck with it! If you want to shoot some decent quality photos while you're IW on it, I'll post them up in a future video to give you a virtual high-five! Email them to me @ unusualattitudesinflight@gmail.com
Very nice! You should make one explaining the prop system including the safety features, valve and pump housings. 👍
I can’t get over how small these engines are.
VP6 Barbers Point Hi. Not sure about C-130 but P3 Orion uses Electric De-Ice on props and I believe on leading edge of wings as well. That's why we had 3ea. 60KVA 400Hz alternators in operation at all times, plus same on APU if needed. That and all the ASW avionics in operation. One of the things I worked on was to check the brushes and slip rings on the prop hub for wear. Oh, and we needed al little extra oomph for the 6 million candle power ARC light for night ops, so we dedicated one whole alternator just to that operation when we used it. Sure miss the good ole days! P.S. always got a kick out of FE's getting testy with newbie pilots, letting them know who was in charge of the critical controls!
That's awesome- wish I would've gotten to experience Barbers Point! Thanks for watching! (OH- and L/E wing de(anti) ice is bleed air off the 14th stage.)
I miss working the T56. I got to go to some cool places while working on it. From there I went to the F108, one of the most reliable engines ever, to now working on the F135. None like the other, and yet all commen in a way
That’s awesome, man; thanks for sharing your story, & thanks for your service! Well....and thanks for watching!! Tell all your friends about the channel!!
Excellent
Air Force T56 mechanic check it in here. In the 80s we used to joke that the P3 turn the engine upside down so they wouldn't shock in water from the waves...... great engines overall to work on if the flight Crews used to some common sense in the crew chiefs weren't newbies. These engines leak a little bit of oil and as long as it doesn't get out of control you're good to go....
Yep- I agree; they are great engines! As far as leaks go, man, if it ain’t leakin’, it’s empty!
@@UnusualAttitudes 100% agree with you
Nice Video Brother!
Thanks dude!
I work on it for CHP application, using gas fuel. Great engine
Please make detailed videos about each component of t56 engine of c 130 . like compressor , propeller, ADH, etc.
So the US Navy uses these on our DDG and CG for Electrical Generation.
We call them Allison 501-K17 and -34. The difference is the K34 is faster.
How 'bout the reset on the low pressure last chance oil filter? The most common pre-flight operation on a T-56. This from an Aviation Machinists Mate from 1983.
Yep, I skipped right over that one, and it’s pretty important, since it’s the last chance to save your a@&! Thanks for watching & pointing that out!
Why there’s no engine stand it’s just seating in the pallet
I assume you’re using the 3.5 series as a NASA/NOAA P3 FE. I’m curious if you’ve heard about the issues we had in the Canadian forces putting the 3.5 on our P3s and if so what your thoughts are? Our install team (myself included) spoke a lot with members of the NASA/NOAA teams and aircrews
I am not aware of those issues; care to explain here? If not, shoot me an email at unusualattitudesinflight@gmail.com. Thanks for watching!
Royal new zealand air force has retired their p3s now got p8s on the way to being rolled put from being fitted up with the gear
So they are doing a tear down in an open hanger and not in a shop!
Hey dude i'm a mechanic allison t56 on c-130 engine same as you, do you want help me to find a troubleshooting and mybe i'll be happy while you answer all my questions about t56, so do you want talk to me or not?
You can share here..maybe someone else can helps
Load Clear
🪂
so is the P3's engine outsidedown or the Hercs??
