The Big Engine - the GE LM2500

The LM2500 is one of the largest engines we work on.
We ran this 30 thousand Hp beast to max power today. It ran smooth as glass, and performed beautifully.

This is the same engine featured in my video from a few months back called Turbine Engine Heat Damage.
Yes, we replaced many parts, and did a lot of repairs.

Much of the high power footage is not included, because my new camera can't handle the noise.
A remedy is in the works.

This literally, is 1 of the BEST YouTube channels ever. It is so interesting to me, to watch, listen, and, learn all of these things about jet engines. Since I was a child, I've been amazed by anything aero related. A BIG Thanks to AgentJayZ, for making and sharing all of this information! A+

Very cool to see the variable stator vanes in action, the linkage to keep these all in sync is amazing. Thanks for the close up !

I was a GSM when I was in the Navy. Great engines. Loved hearing them run when out at sea. Good times. :)

My first job out of school was for a company that packaged the LM2500s and 5000s with generators. Nothing was cooler than getting to work and listening to the gas turbines being started and load tested. Giant columns of steam rising up from the metal plates being dropped into huge tanks of water. Even got to work on the LM6000 engines, as they were introduced in 1991. Learned a lot since then and this video brings back some good memories. Thanks for sharing.

I do appreciate the massive effort to rebuild and run these beautiful engines! The sounds are biblical, but I imagine the smell of burning fuel is equally as indulgent! I worked in the airline industry for 25 years and it never gets old. Thank you! 🙏🏻

Can't these tests wait until spring? You're engines keep blowing your cold Canadian weather down here into Washington. It's been 10-15 degrees colder than normal all winter!

Looking this engine over reminds me of a recip engine mechanic, who referred to us jet mech's as blow torch mechanics. He told me that after looking at the plumbing on an old J-57 engine that all you had to do to become an jet engine mechanic was to take a plumber and knock his brains out. After many years of being a engine man, I tend to believe him now. LOL .

It's 2023 and I get to watch a guy start up one of the coolest things I've ever seen

[TheFantome]

This has to be one of the most beautiful engin I've seen on your channel, it looks brand new !

[leeedwards]

Nice! I worked on these in the australian navy, as they were fitted to our guided missile frigates. 2 26, 000hp lm2500s through a 20:1 double reduction gearbox into a single propeller shaft. I remember many starter oil changes!

Thanks for this video. I worked at GE during the 80's and was responsible for the engineering design of the fuel control for this engine. It's been a long time since I heard one running. I appreciate the chance to hear and see one again.

Work or Art! Seriously LOVED that shot of the variable compressor stators being adjusted by that arm. I think you called them variable stators in another video I've watched, I'm not 100% sure. It demonstrated that the front ring of stators is adjusting more than the rear ring of stators! When I saw that arm moving on the front, I was waiting to see the rear, if it had a synchronized arm doing the same, then I saw that it's just a pivot point at the rear side of the armature 'thingy'. Then it clicked for me that the adjustment is not the same for each row of stators, but evenly reduced going from front to back. AMAZING and GENIUS me thinks! Thanks so much AgentJayZ, I've always wanted a better look at turbine engines! I used to go to the local drag strip when the Jet Cars were here, before they closed Rocky Mountain Raceway. They let us stand right next to where the after burners lit up, and 'first timers' would always run away when they lit them up.

Very cool to watch those compressor stator vanes move.

[dogzebra]

Brings me back to my time in the Navy working on these as well as the Allison K17!

Same engine as what propelled a couple of the destroyers I served on in the US Navy. I loved when we'd conduct at sea refuelings because when we'd break away from the supply ship, the Capt would pull the props back, call for a flank 1 bell then go full pitch. I never thought I'd see/hear a ship which sounded like a DC-10 at full snort...but they did! Very dependable and in an emergency, they could pull a broken engine up through the stack(they were hinged), drop a new one down and be ready to go in about 24hrs. Blistering pace in comparison to the older boiler plants which would require dry dock...

I worked and did my apprenticeship with Rolls-Royce LTD (Aero Engine Division) in Scotland in the late 60's and early 70's. The facility where I did most of my training was in the client overhaul and repair factory for damaged engines. I also did time in development department. We had a large engine test facility that could run up to 5 aero engines at the same time... and the test facility accommodated afterburner testing too. They had large intake ducts and very large exhaust silencers installed and even then you could hear the engine exhaust noise 5 miles away as a low rumble. I remember that one engine failed on its rebuild test run due to the installation mechanic forgetting to take some tools away and they got sucked in through the compressor and the tools destroyed the engine. When we stripped the engine down for repair at RR's cost and found remnants of the mechanic's pliers with his name etched on the handle. Needless to say he did not work there after than incident.
Those were the happy days.
Power to your elbow for producing these very interesting and informative Videos on jet engines. Takes me back.

Thank you for braving the cold for another powerful video. These engines are exquisite examples of engineering and art.

This is the best Youtube Channel!! Really shows us things which are usually off limit if not working in the industry. Thanks for sharing, really valuable!

[tyjoseph]

I love the LM2500 series, the G4 especially. While they may seem “big” they are TINY compared to what a Diesel engine would require in size to put out an even remotely similar amount of horsepower. Any diesel putting out 20, 000 to 40, 000 HP is probably the size of a two-storey house, yet these LM’s can be fit inside the size of an oversized garage. Incredible when you think about it!

[marcguidry]

I was trained on that engine while in the US Navy. I was stationed onboard the USS Fletcher DD 992, out of San Diego, for 5 years. Best time of my life, at the time.
