why would the 1st stage be in the middle of the rotor, its not like that on my F404-GE-400/402

[AgentJayZ]

@mmarchmonte88 The first stage is at the front of the compressor rotor. Some industrial engines have had additional stages added to the front of the compressor, and they are called "stage 0" and in front of that, "stage 00".

The LM1500 has not had that modification, so the stage 1 disc is the first stage of compression.

@mmarchmonte88 I think the way you were looking at it. It looked like the first stage was in the middle because the whole assembly was sitting on top of a stand that looked like more compressor discs but it was not part of the assembly.

@kinsley2108 I never realized that might be what it looks like. You get so used to the parts, you don't realize how strange they may look to those who don't handle them every day.

when you remove the blades do you store them and then they are reused? or do you throw them out?

[AgentJayZ]

@usamabarakat We keep the servicable blades, and repair any that need a little touch-up. If they are damaged beyond servicability, we recycle them, as they are made of high quality alloy steel, or in other engines: titanium alloy.

So if Wikipedia is not accurate enough for you, maybe you should contribute? You seem like exactly the right kind of knowledgeable guy to make a correction to the widely-used public information resource.

@ICESTRONG@ "I just finished 2 years of aviation mechanic schoo training as an Aviation Maintenance Technicain & I love your demonstrations." "I have watched some videos & has helped me understand a great deal, thank you." "The school I went to is called (AIM) Aviation Institute of Maintenance in Duluth, Ga."

[kinsley2108]

@AgentJayZ Yeah, well I figured that looks very expensive so you wouldn't want it sitting directly on the floor, lol.

you can correct wikipedia yourself youknow

Fascinating channel. Informative and entertaining. Thanks for revealing the mysteries of turbine engines.

What a beautiful, harmonious piece of human ingenuity...which can easily be turned into worthless crap by a stray duck or goose!
