Does a ship have transmission to run the propeller?
Some ships do. It is called a reduction gear and takes power from the engine and transmits it to the shaft and propeller. Other ships use direct drive, electric motors, steam or other schemes to power the propeller.

What is a twin screw propeller?
A twin screw propeller refers to a propulsion system used in ships and some boats that employs two propellers, each driven by its own engine or shaft. This configuration enhances maneuverability, stability, and efficiency, especially at slower speeds and during turns. Twin screw systems provide redundancy; if one engine fails, the vessel can still operate with the remaining propeller. They are commonly found in larger vessels, such as cargo ships and luxury yachts.
How much does a propeller weigh?
3 tons
Are thrust loads at a right angle to a shaft?
On a ships propeller shaft, the thrust will be in line with the axis of the shaft.
Why ships propeller in stern?
Ships typically have their propellers located at the stern to optimize maneuverability and efficiency. Positioning the propeller at the rear allows for better control of the vessel's direction and reduces turbulence that can affect propulsion. Additionally, this placement minimizes the risk of damage from underwater obstacles and allows for a smoother flow of water into the propeller. Overall, it enhances the ship's performance and stability while navigating.
What are types of aircraft propeller?
There are two very general types of aircraft propellers: Fixed pitch and variable pitch propellers. Fixed pitch propellers are simply airfoils attached to the engine which spin and due to Bernoulli's principle, cause a lower pressure at the front of the propeller than they do at the back, thereby "pulling" the aircraft forward. They are controlled simply by a throttle lever which directly affects the RPM at which the propeller spins. Variable pitch propellers expand on this concept by allowing the pilot to vary the pitch at which the propeller is angled. By varying this, multiple angles of attack can be imposed on the propeller, meaning the pilot can select a certain angle to achieve greater climb performance, and then change the angle of the blade to achieve greater fuel efficiency. This type of propeller is controlled by two systems - the throttle, which controls the manifold pressure of the engine, and the "prop" control, which changes the angle of the propeller blade.
