WebJul 11, 2000 · When elongated objects (such as fan blades) pass through the airstream, they deflect the air. If we change the orientation of the object relative to the flow direction, we can increase or decrease the amount that the air is deflected. If we progressively increase the attack angle of the fan blade, it will increase the amount of deflection.
