Ive been lurking around here for a while, planning a first gas Turbine.
Ive had an old turbo lying around for a while, and the other night, after a couple of glasses of red I was looking at it:
And a thought occured, I wonder if I con conver this to Axial flow and use it as the basis for an engine.
The turbine and shaft are one piece, and still have the original centers in them.
If I cut and trim it on the lathe like this:
What are the chances of it working as an axial turbine?
cheers

, .......................There are some radial turbs that are "mixed flow" in that they're got a part axial component and are being used in high pressure ratio turbos , but converting a radial turb into an axial one is still fraught with dangers , I've looked at some turbs with the same thoughts as you but whenever I do the maths on such a conversion it doesn't work out , the exducer section is generally a good bit smaller in diameter than the inducer , and as we "normally" need to run an axial turb of ~90-100% of the comp diameter to get sufficient power to drive the comp, a "cutdown" radial turb would need a smaller comp than it would normally have mated to that turb , then theres flow areas at the cutdown's inlet , you'd need to grind away some of the turbs "back wall", this may structually weaken it to the point where it could explode and do some very serious damage to you.
