Power units? (Read 4,157 times)

I have a snapshot of the power unit along a F106, but have no way of sending it. Sorry :scratch_head

Thanks very much! Now I need to find a sneaky way of finding out if these were the ones he worked with...

Well he was in the Air Force in 1963 when my sister was born, and I believe he was also there during the Cuban Missile Crisis, so 1961-1964, approximately.

I thought the F-106 used the M-32A ground power unit,because of all the different voltages it used.

The A/M32A-13(engine driven) and AF/ECU-10M (electric motor driven) generators were used for power prior to the PUP (power upgrade program). The six was started with 3250 PSI air pressure at 15 CFM from an MC-11 air compressor. After the PUP power was supplied by MD-3 (engine driven) and an electric driven generator which I cannot remember the model designation of. Pat's pictures above show, from top to bottom, the MD-3, the MC-11 Joy compressor, and the MC-1A Joy compressor. MC-1A wasn't used to start aircraft but to service. The earlier versions of the MC-11 were made by both Ingersoll Rand and Worthington.

C-26


MD-3

Man, talk about cobwebs.
All this talk about power carts has me wondering about the ones we used to start the pre-Century Series birds. The small one had a 4 cylinder aircraft engine and was a one-man mover. The bigger one was over 6 feet tall, about 8 feet long, and had a Chrysler V8 for power. We also had Jeeps with an extra 24 volt generator on top of the engine, it had a big blister on the hood. All of them were used on the line at The SCAB.

Thinking of equipment.
What about Tugs?
I remember the little tugs with a Dodge flat-head 6 engine in them that would go any place and could pull pretty big birds. We also had one that was a monster. Had a big engine and two steering wheels, one in the front and one in the back. All four wheels steered and you could almost turn that big dude in it's own length. It was pretty long, so not a big deal. It was as tall as a semi-tractor. Then there was the Coleman tug, with the crew seats in the back, out in the open, of course.

Can anybody come up with names and/or pictures?

Here's what he answered:

"ecu-10, m32a-13"

Thanks a lot for all your help! I'll try and post pics of the model if it's worth seeing.

The air conditioner I couldn't remember the maker of was Keco (a huge heavy brute of a thing). They all had propulsion systems to begin with but, could not be supported when shown to be unreliable and were disabled. A contributing factor was people running them into things. There were a lot of units with propulsion systems. The only ones that lasted were the MD-3 family and the -60 turbine compressors/generators. The MD-3 had a tendency to lunge at you and the -60 had a puzzling time delay. Oh, earlier power units. One with a four cylinder engine was the A-1. Sounded like a machine gun when running. The one with the four cylinder engine was a C-21, I think. The one with the Chrysler Fire Dome V8 was the A-7. All of those were 28 VDC output only. I remember the MB-4 Coleman. It was our go-to when we couldn't get AGE out of or through deep snow. Our Ford tractors, even with antifreeze in the tires were good but, not that good. And the Case tractors were a piece of cr*p. There was a later "Coleman" that had 4 wheel steering. Think it was designated an MB-4 also. The big monster was a Uke and did have 4 wheel steering. Don't remember the designation. We used it to tow the E-3As. The "little" tugs I remember were made by Clark, among others. They would pull OK if the ramp was dry but, had no traction in the snow. Plus the front end was a half inch steel plate that allowed only about 6 inches of ground clearance. Thanks. Cobwebs almost gone now. I am sure they'll be back though.
