Can airplane engines be used for other purposes, besides powering airplanes?

I did read in this forum, about someone who was planning to use Convair 880 engines to generate electricity on an oil drilling platform, but the plan was abandoned.

Are there other, more successful examples?

Allison 501-D13 (T-56) engines are used in oil pipeline pumping installations, or at least they were when the first Alaskan pipeline was built.

I will do more research to verify, but I believe the BAe-146 engines share a core with the powerplant in the M1-A1 Abrams tank.

4 cylinder piston engines are/were used on those air boats used in swampy areas. The engine would drive a caged propeller, and steering is via move able rudders in the airstream.

Some railroads in western North America bought some surplus jet engines (forget model number-the type that was used on the P-2V Neptune and C-119) and mounted them to snowplows. They apparently did a great job ob blowing the tracks clear of snow. I imagine it would have been as impressive as hell...one of those first generation turbojets screaming away, creating a huge rooster tail of snow!

Paris Charles de Gaulle used to have an array of jet engines beside the runway to dissipate fog. They were fired up on request, and the airlines got a hefty bill. That was used as late as 1974 I think.

After Gulf War 1, when the Kuwaiti oilfields were ablaze, there was an oil field fire control company using MiG engines to blow the fires out.

While I'm thinking about tanks, the WW ll American tanks had radial engines, Franklins and Jacobs and Lycomings that were also used in aircraft.

Some ships have gas turbine engines, but I will need to research the commonality with aircraft.

In the 60's Ford Motor Company produced a PT-6 powered transport truck prototype. I'll find a picture...

I believe that some of the RN Destroyers are powered by a combination of RR Tyne and RR Olympus engines. IIRC the Tynes are used for normal ops and the Olympuses for hi-speed dashes.

Yeah, I was just reading some Google results, and was surprised to see the Spey mentioned as well.

I think I was wrong about the PT-6, BTW. The Ford history pages don't mention it by name. Chrysler also had some experimental cars-its worth googling "Chrysler turbine car" and "Ford Turbine Truck" to see some groovy Jetsons automotive styling.

Several GE engines are used for power generation, as well as for propulsion in ships. For example, the USN Arleigh Burke class destroyers (DDG-51) use four GE LM2500 gas turbines, which, IIRC, are derived from the CF6 engine. I believe that the LM1500 is derived from the GE J-79, and is widely used in power generation.

IIRC, turbocharged models of Subaru's EJ20, EJ22 and EJ25 engines are sometimes used on small propeller planes. The compact design of the boxer engine makes it ideal for fitting into the small spaces. Keep in mind these engines are usually found in cars like the Impreza, Legacy and Forester.

I remember a small "gyppo" sawmill in the Pacific northwest that was run by a single Allison V-1710.

I also saw an 18-wheel lumber truck powered by an Allison. IIRC it was about a 1950 or so, Stirling. He ran it with no side panels on the hood and you could see the big V-12 in there.

I know a USAF radar station that uses a British-made gas turbine engine to generate electricity. The small base uses electricity purchased from the local utility company. It constantly samples the incoming power and if a power loss is sensed, the engine is signalled to start. One hundred and ten 1-volt batteries, each bigger than the battery in your car, (beaucoup plate area!) connected in series, crank an electric starter on the turbine. When it comes up to speed and its output is stable the base unplugs from the power company and it takes over. It has surplus capacity sufficient to backfeed the power line to the nearby town.

Gas turbine engines in stationary use, like generators and pumping stations probably run a very long time between overhauls.

http://upload.wikimedia.org/wikipedia/commons/e/e5/Union_Pacific_18.jpg

Because many of these locomotives were built by ALCO, and the electric components were supplied by GE, my guess is that it had a GE engine in it, but I am not sure on that. Supposedly, these were the most powerful locomotives ever built, developing 10,000 horsepower.

Many years ago when I first started out in aviation, I was working at a repair station and one of our mechanics who had worked on J-47’s in the Air Force used to go to Yonkers Raceway every November to change the oil and fuel filters and start up for the winter season the J-47’s that the racetrack had mounted on trucks to clear snow from the track.

Also every once in a while during the winter he would also have to go and work on the engines when one of them would not start or run properly. This lasted for about 2 years when Yonkers decided to do their own maintenance.
