Propellers produce thrust through t

Propellers produce thrust through the production of lift by their rotating
blades. Propeller hydrodynamics is therefore part of the broader field of
lifting-surface theory, which includes such varied applications as aircraft,
hydrofoil boats, ship rudders, and sailboat keels. Air and water propellers
have much in common from a theoretical point of view, particularly if one’s
attention is restricted to air propellers operating at low Mach numbers
(where compressibility effects are negligible) and to water propellers
operating without cavitation. The cross sections of most lifting surfaces are
also similar in appearance, being designed to produce a force at right angles
to their motion through the fluid (lift) with a minimum force parallel to their
direction of motion (drag).
