Axial fans are divided into three groups: propeller, tubeaxial and vaneaxial. Hence, every propeller fan is an axial fan but the opposite is incorrect.
The rotor is like the engine to the propeller. A propeller is the fan like blades on the top that spin to make the helicopter fly.

Excrement - it is "when the excrement hits the rotating propeller blades."
The propeller on a turboprop airplane engine spins to move the aircraft through the air. It acts in a way similar to that of the blade in a fan.
Engine cooling fan clutch locked up.
A propeller is the object on the aircraft that rotates to produce thrust almost like a fan makes wind... it aims the wind behind it and pushes the aircraft forward
it looks like a small table top fan blade
A Carrier brand dehumidifier propeller fan costs $114.88. The fan blade set kit itself costs only $14.99 (from Emerson).
Used as fasteners, a fan or ships propeller is a form of screw, etc.
Extract means "pull out", and a fan in this case is probably a propeller-like thingy used to move air. So an extractor fan is something that's used to draw air away from a certain area.
A propeller works by converting the rotation of the engine into horizontal thrust similar to a fan. The blades push the air backwards creating acceleration, and create a difference in pressure between the forward and rear surface adding to the movement. The above is, of course true for a boat propeller. For an airplane propeller Bernoulli's pincipal is involved. Bernoulli's principle states that the greater the speed of a fluid, the less the lateral pressure. So the propeller uses the same deal as the wing.
