Propeller

A Propeller is a rotating device powered by the engine of an aircraft that creates thrust to propel the airplane through the air. It is a type of airfoil that generates lift and drag by spinning in a circular motion, producing a force that is oriented approximately perpendicular to the plane of rotation. This force pushes the airplane forward and helps it to overcome the resistance of the air. The propeller includes various control components, such as pitch control and blade angles, which are designed by the manufacturer to optimize its performance under different flight conditions. The propeller can be mounted either in front of or behind the engine, and it can consist of two, three, or four blades depending on the design of the aircraft. The size and shape of the propeller blades are also determined by factors such as the engine horsepower, the aircraft weight, and the desired operating speed. In addition to propelling airplanes, propellers are also used to drive boats, helicopters, and other types of vehicles through air or water.
