Default RE: Compressor stall?? Help!

Hi, I agree with others here, it was a good explanation of how a jet engine works! But I have read that radial compressors like in miniature jet engines for rc use- (i don't like saying "turbines" as most people do, because it is inaccurate, we have all kinds of turbines; water turbines, wind turbines, gas turbines etc the turbine (wheel) is only half the engine. a micro gas turbine or jet engine is better to say! [8D] ) -can not stall!(?) to me it seems logical, because an axial compressor is just like a wing of an aircraft, it can of course stall if the incidence is too great, or the speed of the flow is too great, and you get flow separation over the entire upper surface of the blade/wing which is a stall. But I don't know if an axial compressor really can stall, because all it does (as explained by you) is to rotate the air so it is sent radially outwards and compressed by sentrifugal forces. It would have been great if a jet engine company could explained this!
