HOW The SHIP MOVES through Water
HOW The SHIP MOVES through Water - A propeller is a rotating fan-like structure which is used to propel the ship by using the power generated and transmitted by the main engine of the ship. That's the most straightforward answer for one of the most common questions asked about ships - How Ship Run in Water? or How does ship move in water?
The transmitted power is converted from rotational motion to generate a thrust which imparts momentum to the water, resulting in a force that acts on the ship and pushes it forward.
Marine propellers are made from corrosion-resistant materials as they are made operational directly in seawater which is a corrosion accelerator. The materials used for making marine propeller are an alloy of aluminium and stainless steel. Other popular materials used are alloys of nickel, aluminium and bronze which are 10~15 % lighter than other materials and have higher strength.
Let's see how the thrust generated by the propeller helps the ship to move forward or backwards - HOW The SHIP MOVES through Water
