BladeCleaning What's this?

Stall. If the angle of attack is low, passing air flow over the blade is attached to the blade's surface. Given the shape of the blade, air speed on the upper side is higher than in the lower one (pressure is lower in the upper side), creating an ascending lift force (rotational in the case of a turbine).
