A propeller is an airfoil. That's why it produces lift. A flat board
presented at a slight angle to a stream of air also produces lift and
is also an airfoil, even though it is not curved.

The curved cross-section of most airfoils increases the critical angle
of attack for stalls and reduces drag, but it does not improve lift
and is not necessary to produce it.
