Turbine engine parts... what 'n the heck are these?
These parts came from a stationary turbine engine we have had in our school shop for some years. I nursed notions of trying to fire it off... but now am glad we never did.
We had some of the boys tear it down for the fun of it, and will be scrapping the remains. Inside we found gears missing enough metal to build a rockcrusher transmission. Most of it we can decipher.... but not these.
These 'discs' are geared to spin, and are placed directly in the exhaust stream of the turbine. All the exhaust passes through these discs before exiting the engine. They are roughly 25" in diameter, and 3" in thickness. They are composed of a metallic honeycomb that is goldish in color. The metal is magnetic. Despite their size, I can easily pick each up by myself, or hold one up by one hand if I wished to.
What are they, and what is their purpose?
What is the honeycomb metal?
A 'scrap metal expert' pronounced them to be carbon steel with some kind of rinkers coating.
"Ah know xactly what dey are.... Give you numer one steel price for them".
Seriously... what are they made of, and what are they for? A couple of the kids are just dieing to know.... and me too.
