Ming-style steamship lesson plan
A steamboat with wheels on both sides is called a steamboat with visible wheels. Because the wheels are partially exposed above the water, it is called a steamboat with visible wheels. A steamboat with visible wheels is a ship that uses visible wheels to push forward. The original steamboat with visible wheels is pushed forward by stepping on wooden wheels.
After the modern era, steam engines were used on ships to become the ship's power, and the propulsion tool that cooperates with the steam engine is the paddle wheel. It is equipped with blades around the periphery of the rotor, becoming a rotatable paddle wheel, mounted on the sides or the stern of the ship.
The stern wheel is divided into side stern wheel and stern wheel according to the arrangement position.
Steam engines drive the propeller, which rotates the propeller blades to splash water, propelling the ship forward. Since the steam-powered ships are equipped with propellers, the ships that are propelled by steam engines driving propellers are called steamships.
The propeller is a step forward from the oars, paddles, and rudders, its main feature being that it can operate continuously, converting human or mechanical power into the propulsion force of the ship, enabling the ship to move forward.
However, it is bulky and inefficient, especially in rough seas, where the propeller blades may partially or completely emerge from the water, making it difficult for the ship to navigate stabilily. Moreover, the propeller blades are prone to damage during use. When the propeller rotates, half of the blades are in the air, not only increasing the ship's width and resistance during navigation, but also making it easy to collide with adjacent ships when docked. This not only endangers the safety of its own operation but also poses a risk of damaging other ships. Additionally, if entanglements such as aquatic plants get caught in the propeller blades or shaft, the propeller may lose its ability to rotate.
It was the drawback of the paddle wheel propeller that by the 1860s, the paddle steamers were replaced by advanced steamships equipped with propellers.
