But this propeller with 6 blades (second picture) seems the AoA or pitch is not as that 'rule'. Webpropeller can be "feathered" (turned to a very high pitch), with the blades almost parallel to the airstream. This eliminates asymmetric drag forces caused by wind milling when an engine is shut down. A propeller that can be pitched to this position is called a full-feathering propeller.

http://avstop.com/ac/flighttrainghandbook/propellerfeathering.html In aeronautics, blade pitch refers to the angle of the blades of an aircraft propeller or helicopter rotor. Blade pitch is measured relative to the aircraft body. It is usually described as "fine" or "low" for a more vertical blade angle, and "coarse" or "high" for a more horizontal blade angle. Blade pitch is normally described as a ratio of forward distance per rotation as…
