Stall individual blade

There are three distinet stall phenomena. Rotating stall and individual blade stall are aerodynamie phenomena. Stall flutter is an aeroelastie phenomenon. 

This type of stall occurs when all the blades around the compressor annulus stall simultaneously without the occurrence of a stall propagation mechanism. The circumstances under which individual blade stall is established are unknown at present. It appears that the stalling of a blade row generally manifests itself in some type of propagating stall and that individual blade stall is an exception.
