A propeller (colloquially 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. [1] .

The meaning of PROPELLER is one that propels; especially : a device that consists of a central hub with radiating blades placed and twisted so that each forms part of a helical surface and that is used to propel a vehicle (such as a ship or airplane).
A device consisting of a set of two or more twisted, airfoil-shaped blades mounted around a shaft and spun to provide propulsion of a vehicle through water or air, or to cause fluid flow, as in a pump.
A propeller is a rounded blade that rotates in a circle, helping to move a vehicle by pushing against water or air. A speed boat's propeller moves it forward by spinning against the water. Propellers use the laws of physics to propel, or drive forward, an aircraft or a boat.
A propeller is a device with blades which is attached to a boat or aircraft. The engine makes the propeller spin round and causes the boat or aircraft to move.
propeller, device with a central hub and radiating blades placed so that each forms part of a helical (spiral) surface. By its rotation in water or air, a propeller produces thrust owing to aerodynamic or fluid forces acting upon the blades and gives forward motion to a ship or aircraft.
1. a device having a revolving hub with radiating blades, for propelling an airplane, ship, etc. 2. a person or thing that propels. 3. the bladed rotor of a pump that drives the fluid axially. 4. a wind-driven, usu. three-bladed device that provides mechanical energy, as for driving an electric alternator in wind plants. [1770–80]
a device with two or more long, flat blades that turn quickly and cause a ship or an aircraft to move forward. The propeller suddenly stopped turning. Extra Examples. Topics Transport by water c2, Transport by air c2. Want to learn more?
