Origin of water motorboat
Water motorboat is a kind of sports racing on the water, which is launched by gasoline and diesel. It comes from the late 19th century. What is the origin of water motorboat?
At the end of the 19th century, a yacht club in the United States was established and later unified into the American power boat club. Because the technology was not developed at that time, they formed an alliance. Later, after the engine was invented. This movement gradually developed. In China, motorboat started in July 1956, and the competition was held in Wuhan. Later, in 1981, China officially joined the Power Boat Association of the United States.
The basic principle of the motorboat is to generate water flow through a spray driving device, so that at the bottom of the motorboat, under the push of the impeller, the guide pipe sprays to the back of the motorboat, which is this thrust, and the motorboat keeps moving forward. The principle is different from that of a rocket.
As we all know Newton's third law of motion, force and reaction are mutual. Therefore, in order to make the boat move forward, it is necessary to generate opposite thrust to form water flow. Make it run in water. The impeller is similar to a rotor. The engine transmission shaft drives the rotation of the impeller, and the blades of the impeller flow out rapidly, driving the water flow and steering guide pipe through the cylindrical channel.
When operating a motorboat on water, it is very important to have a cable, which controls the rotation of the steering guide pipe at the rear of the motorboat. Through this control method, the size of water flow can be changed to change the running speed. If the water flows to the right, it needs to shift to the left, and the same is true.
