Which do you want to describe? Screw-type (for water) and "blade"-type
(for air) propellers are very different. Aircraft propellers and
helicopter rotors are essentially spinning wings.

I'd be comfortable with those words, but I would interpret them as
referring to the change in orientation of the *wing* rather than that
of the rotors. So they might not be great for effective communication
unless you added extra clarification.
