propeller blades

The purpose of propeller blades on ocean liners is to create a force that propels the vessel forward. The blades are usually made of metal (e.g. manganese bronze), and their shape and pitch angle can affect how much power the propeller generates. In modern propellers, the pitch angle of the blades can be adjusted to control the speed and direction of the ship. The propeller blades are mounted beneath the hull of the ocean liners and are driven by powerful engines. As they rotate, they pull water toward the stern of the ship, creating a force of propulsion that moves the vessel forward. However, the design of the blades must also be able to effectively disperse the water that is pushed by the blades to ensure that the ship remains stable and easy to control. The size and shape of propeller blades on ocean liners can vary depending on the size and type of vessel. See Olympic and Titanic Shafting and Propellers
