- Propeller - Wikipedia
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 [1]
- Propeller | Aircraft, Aviation, Design | Britannica
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
- Propellers | How Things Fly
Think of a propeller as a spinning wing Like a wing, it produces lift, but in a forward direction—a force we refer to as thrust Its rotary motion through the air creates a difference in air pressure between the front and back surfaces of its blades In order for a propeller blade to spin, it usually needs the help of an engine
- How do propellers work? - Explain that Stuff
Propellers, often shortened to "props," are sometimes called screws —and it's easy to see why To push a screw into the wall, you apply a clockwise turning force to the head with your screwdriver
- Aircraft Propellers – Introduction to Aerospace Flight Vehicles
Today, companies such as Hartzell, Sensenich, and McCauley produce highly efficient, advanced propellers made of composite materials, aerodynamically optimized airfoil sections, and sophisticated blade geometries with swept leading edges to minimize compressibility effects

The propellers are long, thin, twisted pieces of wood which are spun at high speed The propeller blade is shaped like an airfoil and there is a pressure difference created across the blade because of the motion of the spinning blade
