Has anyone tried a diagonal compressor?

I guess diagonal the gas leaves the back of the wheel and radial the gas leaves the OD of the wheel

James,
if you really like the obscure, try to find the one wheel turbine. It's a turbine with one wheel! The rotor looked just like a turbine wheel but with thick hollow blades. The compressor was the hollow blades! There was a cavity at the root of the wheel where all the intake air went in and was flung outwards into a diffuser through the hollow blades. The air looped around through a combustor and back through the turbine wheel. The hollow blades were cooled by the intake air as a benefit. The problem is the compressor design was horrible.

try to make a drawing of that!

Ooooo.....a challenge.

I accept.

May take some time finding enough information on it though.

Ha....I found it:

It was a design from Los Alamos.

I see a problem already. Because the whole unit is spinning, I do not see a way to seal the combustion chamber to the power turbine section well enough to prevent cross over (bleed over into the intake section).

Also...they had a radial power/drive turbine design which would have poor efficiency.

I'm going to do some more research, but I doubt any results will happen. I could draw it, but it would suffer from in ability to seal the unit properly. Would make for a small turbine if the sealing problem could be overcome.
