The Allison T-56 | The Engine that Powers NASA's P-3, C-130 & Super Guppy Transport

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!
