Propeller blades are designed with a twist with higher angle at the hub than at the tip. This is to equalize the lift distribution along the blade to the extent possible.

If the blade did not have twist all along from hub to the tip, there would be dissymmetrical rotation speed and consequently lift. Hence, the necessity for blade twist.
