Propeller

A propeller is a rotating device that converts power from an engine or motor into thrust, which propels a ship through the water. It consists of a hub and several blades that are shaped to generate lift and propulsion as they rotate. The pitch of the blades can be adjusted to optimize the performance of the propeller for different speeds and conditions. Propellers can be made from various materials, including bronze, stainless steel, and aluminum, and can have different numbers of blades depending on the size and type of vessel. The efficiency of a propeller is affected by factors such as the diameter, pitch, and blade area ratio, as well as the speed and direction of the water flow around the blades.
