Very nice :D
Professional finish with "correct" blading , unlike another persons on this forum.
I'm quite aware of the requirements of axial compressor design as at one stage several years ago I was considering making a single stage axial compressor driven by the freepower turbine I eventualy used to power my bike ....

to make a lowpressure "afterburner" using air from the single axial comp stage .
I did all the design stage work but the theoretical thrust outputs and fuel burn rates , gallons/minute :( from the air mass flow rate of ~8-10 lbs/sec , finally sent me on the freepower turbine driving a gearbox and drive chain route instead.
Yeh , small overall diameter is the beauty of axial compressors , basically they're only the "normal" inducer diameter of a centrifical type , its just the low pressure ratio per stage and the need to build several stages that lets them down .
I dare say you were only running a pressure ratio of ~1.5:1 with modest efflux velocities , but with a fairly decent mass flow rate compensating and providing the thrust , how was your fuel burn rate ?
