tubs rotating stall

[@michaelstead3567]

Excellent visualization of axial fan rotating stall propagation. The moving triangles are the velocity vectors of the blades (same length) and the incoming air (Which they vary) giving a resultant vector which moves around. The angle of attack is dependant on the blade vector(constant) and varying the air velocity (flow rate) through the fan.
