Propeller

A propeller is a type of rotating airfoil that produces thrust by converting rotational motion into thrust. It consists of two or more blades that are twisted to create a helical shape, which generates lift as it rotates through the air. Propellers are commonly used on aircraft to provide propulsion, and they come in a variety of shapes and sizes depending on the type of aircraft and its intended use. They can be powered by piston engines, turboprop engines, or electric motors, and are typically made of lightweight materials such as aluminum or composite materials.
