Propeller - Wikipedia
WebA 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.
Propeller (aeronautics) - Wikipedia
WebPropeller (aeronautics) The propellers of a C-130J Super Hercules military transport aircraft. In aeronautics, an aircraft propeller, also called an airscrew, [1] [2] converts rotary motion from an engine or other power source into a swirling slipstream which pushes the propeller forwards or backwards.
Propellor Definition & Meaning - Merriam-Webster
WebThe 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).

WebMar 18, 2024 · 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.

WebPropellers. A Propeller “Lifts” an Airplane Forward. 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.

WebApr 12, 2022 · A propeller is a machine that moves you forward through a fluid (a liquid or gas) when you turn it. Though it works the same way as a screw, it looks a bit different: usually it has two, three, or four twisted blades (sometimes more) poking out at angles from a central hub spun around by an engine or motor .
