Design
Propellers are often shaped like a fan or airplane propeller, and have three to six blades that are pitched at an angle. .
How they work
Propellers work by creating a pressure difference between the front and back of the blades, which pushes the ship forward. This is similar to how a screw is pushed into a wall by a helical thread.
Materials
Ship propellers are often made from alloys like brass because saltwater can corrode other materials.
Installation
Propellers are installed at the bottom or back of the ship, depending on the ship's design. They are secured to the tail shaft using a locking nut. .
Performance
The design and selection of a ship's propeller is important to ensure the ship operates safely and optimally.
