Propellers

Propellers are rotating blades used to propel a vehicle, typically a ship or aircraft, through a fluid medium such as water or air. They generate thrust by accelerating the fluid in one direction, resulting in a corresponding force propelling the vehicle in the opposite direction. Their design is crucial, as factors like blade shape, pitch, and number affect efficiency and performance. Modern propellers are often made from lightweight and durable materials like aluminum alloys or composite materials to enhance fuel efficiency and maneuverability.
