Neat stuff

I'm not standing near the cast iron jet engine.

33,000 rpm ......so, they made a gas powered Dremel.  Ok.

OK, so I have a dumb question. If you take a full size engine, say a J33, which is already small, and reduce it to CAD files, couldn't you then tell the computer to produce a miniature version of the larger engine that was identical in every way?

That's cool.

I don't think fluid dynamics scale properly for that. It would be cool as hell if it did, though.

Really cool! But I saw no mention of thrust?



Maybe this will bring the prices down across the board!

Neither will bearing loads. Many clearance gaps and such may actually be the same as in no scaling at all.

Any fits will not scale.  Fits are determined by the type of fit and size of the part.
