ship propeller
When we talk about ships these days, we no longer talk about ship screws, but use the word "ship propeller". This is the technical term that people use to describe the part that drives the ships.
Imagine you are on a large ship gliding over the waves. What actually makes this ship move? The secret lies in the ship's propeller.

When the ship's engine is running, the ship's propeller starts to rotate. It takes the water in front of it and pushes it backwards - similar to diving into the water with a paddle. This movement helps the ship to move forward.
The principle is called "reaction force". When the propeller pushes the water backwards, the ship is pushed in the opposite direction. This is how it moves forward.
There are many different types of boat propellers, designed in different ways to give the best performance. You might think about what shape would work best if you were designing your own boat. How fast would it go?
By understanding how a ship's propeller works, we understand the connection between technology and movement. It is an exciting journey that invites us to learn more about the world around us.

Here are some different types of ship propellers used in shipping:
Fixed propeller: This propeller has a fixed blade angle and cannot be changed. It ensures consistent performance and is often used on cargo ships.
Adjustable propeller: These propellers can be adjusted while sailing, allowing you to adapt the power to different conditions. They are often used on yachts and other boats that need to be flexible.
Multi-blade propeller: These have multiple blades that move water simultaneously. They are very efficient and provide a lot of thrust, which is why they are often used on large ships and ferries.
Fast propeller: These propellers are designed to reach high speeds and are often found on fast ships and racing boats.
tug propeller: These special propellers are used on tugboats. They are robustly built and offer a lot of thrust, even at lower speeds.
displacement propeller: These propellers are designed to displace a lot of water, which is important for heavy ships to ensure stability and efficiency.
Gliding propeller: These propellers reduce resistance in the water and ensure a smoother ride. They are often used on modern yachts and fast passenger ships.
Each of these propellers has its own advantages and is designed for specific applications. It's exciting to discover all these different designs and understand how they affect shipping. We've probably overlooked or forgotten some. Regardless, we've already delved pretty deep into the world of ship propellers.

Phew, that was quite a lot. Please let us know if we have described something incorrectly, if you have any questions, or if you are perhaps very familiar with it.
