What's the function of hovercraft?

The hovercraft is also called the" hovercraft",?It is a use of air support force rising from the surface vessel. The ship appeared immediately by the whole world shipbuilding circles.

The hovercraft is a British engineer who invented cocl. In 1950, 40 year-old CoCl I loved the shipbuilding industry. He resigned from the original work, with all his savings, with his wife founded a small shipbuilding company. At this moment, I view in my mind to consider is how to create a faster boat. He thinks the boat speed lift is not high due to the bottom and the surface friction between the resistance. After repeated study, he found that if the air is used as the ship and the water between the" cushion" it is possible to reduce friction, thus improve the ship speed. I take this view idea of concrete, in his empty tins of cat food with an empty coffee pot, with the hair dryer blowing power experiment. The results, by exhaust generated floating effect made him very satisfied. Then he made about 0.5 meters, model boats, in the experiment, and success. Its principle and the practical principle of hovercraft is exactly the same.

At this moment, I prepared to view his invention was sold to entrepreneurs, but were rejected. Reason is very interesting, marine manufacturers think it is plane rather than ship. However, the research and development company general manager Hals Perry is Dujuhuiyan, foresaw the importance of hovercraft, help CoCl I granted the patent right. At that time, I joined the NEDC CoCl company, started manufacturing a 9.1 meters long, 7.3 meters wide hovercraft. The hovercraft smoothly across the English channel, becoming the world's first practical sailing ship. Fully display the superiority of hovercraft.

Hovercraft are mainly two forms: full floating and side wall. The largest passenger hovercraft, to the number of the British-built SRN4 - III type of hovercraft. It is used in floating, characterized in that air propeller ( as aircraft propellers ), the bottom of the boat is provided with nylon rubber cloth." Apron", since the bottom of high pressure air injection, in the bottom and surface is formed between the air cushion support hull weight, in order to reduce the running resistance. The average speed of 100 kilometers per hour, can carry 416 passengers, 55 cars. The fastest is the United States of America 's sidewall hovercraft, up to 167 kilometers per hour
