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.

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.
Propellers | How Things Fly
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 .

WEBMay 13, 2021 · A C-130 transport plane is a turboprop aircraft. Its main thrust comes from the propellers, but the propellers are turned by turbine engines. The human-powered aircraft of the mid 80's were also propeller-powered, but the "engine" was provided by a human using a bicycle gearing device. Currently NASA is flying a solar-powered, electric engine ...
