What kind of machines are used to produce air beds and hovercrafts?

1. Air beds are mainly used for human family sleep and medical care. Airbed is including air cushion body and set in its inflatable mouth, in the said air cushion body is set outside the fixed frame, characterized by the fixed frame by the four walls of the frame body and set in the bottom of the bottom of the composition of the air cushion body placed in the fixed frame, the height of the four walls of the body and the height of the air cushion is equivalent to the height of the air cushion; in the said air cushion body is equipped with the outer jacket, in the said bottom of the body under the set of the bed frame body. The air mattress bed has a very strong sense of throwing floating, soothing and soft feeling, it is the use of the overall mobilization of the gas, through the force and reaction force, is any other material made of bed irreplaceable function. Because the air mattress bed is a whole structure, it has the aesthetics of the new era. The production equipment is simple, easy to operate and economical. It also has a bed of multi-functional features: soft and comfortable bed; cool bed (because the bottom plate is made of iron mesh); hard bed function (because the mattress will be turned over one side of the iron mesh material; inflatable and convenient, with breathability).

2. hovercraft

Air hovercraft, also known as the "vacate the boat", is a kind of use of air support to lift off the water surface of the boat. This kind of ship immediately appeared by the world's shipbuilding industry attention.

The hovercraft was invented by British engineer Cockerell, who fell in love with the shipbuilding industry at the age of 40 in 1950. So he quit his old job and used all his savings to start a small shipbuilding company with his wife. At this time, Cockrell's mind is to consider how to build faster boats. He believed that the reason for the lack of speed was the friction between the bottom of the boat and the water, which created resistance. After repeated research, he found that if the air as a boat and the water between the "air cushion" it is possible to reduce the friction, thereby increasing the speed of the boat. Cockerell materialized this idea, he installed an empty coffee can on top of an empty can of cat food, and experimented with a hair dryer as a power source. He was very pleased with the resultant lift by exhaust. Then he made a model boat about 0.5 meters long, and experimented in the river, which was again successful. Its principle is exactly the same as that of today's practical hovercraft.

At this point, Cockerell was ready to sell his invention to entrepreneurs, but all were rejected. The reason was interesting; shipbuilders considered it an airplane rather than a ship. But Halsbury, managing director of the British Research and Development Corporation, had the insight to foresee the importance of the hovercraft and helped Cockerell obtain a patent. At that time, Cockerell joined the NEDC company and began to formally build a 9.1-meter-long and 7.3-meter-wide hovercraft. This hovercraft successfully crossed the English Channel and became the world's first hovercraft to actually sail. It also fully demonstrated the superiority of the hovercraft.

There are two main forms of hovercraft: full-floating and side-wall. The world's largest existing air cushion passenger ship, to count the British-made SRN4-III type hovercraft. It adopts the full-floating type, characterized by air propeller propulsion (as the same as the aircraft propeller), the bottom of the boat is equipped with nylon rubber cloth made of "apron", high-pressure air from the bottom of the boat shot, between the bottom of the boat and the surface of the water to form a cushion of air to support the weight of the hull, in order to reduce the resistance to navigation. The average speed of 100 kilometers per hour, can carry 416 passengers, 55 cars. The fastest speed is the United States side-wall hovercraft, up to 167 kilometers per hour.
