A propeller is a rotating device with angled blades that pushes vehicles forward by moving through air or water, commonly found on ships and aircraft. It works by spinning to create force that propels the vessel or plane in the desired direction.

A propeller (often called a screw if on a ship or an airscrew if on an aircraft) is a device with a rotating hub and radiating blades that are set at a pitch to form a helical spiral which, when rotated, exerts linear thrust upon a working fluid such as water or air. Propellers are used to pump fluid through a pipe or duct, or to create thrust to propel a boat through water or an aircraft through air.
