I bought these from a metal scrapper and paid about $30.00 total figuring they're worth more than that in cool factor. Problem is they aren't nearly as cool if I can't figure out what engine (and hopefully aircraft) they come from. All I know is the compressor blade is titanium and the turbine blade has a high nickel content. So here I am hoping someone has an idea.

Also what might cause the wear patterns at the tip of the turbine blade? I appears like it may be cracked and then repaired. I cant imagine they would repair damage that extensive.

I cant find any pitting on the edges of either blade, leading me to believe neither blade was ever used, is my thinking correct?

    $\begingroup$ It might not have even come from an aircraft engine either. $\endgroup$ Nov 8, 2017 at 17:10

    $\begingroup$ It may help if you include some measurements. $\endgroup$

Turbine Blade The turbine blade (part number 1475M35P01) is from the High Pressure Turbine (HPT) a CFM56-3 according to this ATSB report on performance testing of the engine. The report contains several images of blades which look similar to your photos.

Compressor blade A search on locatory.com for the part number (B778503) lists the description as C-3 suggesting it could be a Stage 3 compressor blade. This would fit with the high aspect ratio of your blade.


The part number on the turbine blade shows it comes from a CFM56-3 series (Boeing 737 classic). No hits on the compressor blade, but it looks similar to one from the same engine.
