The Hovercraft has made a huge impact on the society, you may not see it, but it really has. Some basic information about the Hovercraft and it's use.The bottom of the Hovercraft is supported by an air base, which pushes the vehicle off the ground. Now that the object is off the ground, the air reduces surface friction (drag). The smallest little bump or ridge, can possibly damage the air cushion. The Hovercraft has a few basic sections that we can identify. 1-The hull which is attached below the skirt. 2- The carriage or cabin, the section that which holds the passengers. 3- A propulsion system, basically the engine. 4- The lift system, the air cushion.The Hovercraft wasn't known for having a great amount of weight, the more weight, the less the Hovercraft can carry. The Hovercraft isn't heavy, but carries a lot of power. The Hovercraft's engine, will work better if it has a better ground clearance, but if the air lift is too high, then the Hovercraft's control can be lost.The Hovercraft strength is tricky, you need a light enough raft to be lifted by the air cushion, but strong enough to carry the engine, the passengers or payload. Wood is often used, but most commonly used is aluminum welded together ("Hovercraft construction "). ======

 The Hovercraft is used for people's amusement, but it's also used for recreational, search and rescue, mass transportation, research and military use. The military uses the Hovercraft to get through the terrains quickly, to keep on task and not waste time.The Military uses Hovercraft for landing troops, equipment,food, instead of transportation over land or water,("Hovercraft construction "). ======

Sir John Thornycraft, designed a new way for ships, so that the drag of water would be reduced. In 1877 he patented his idea and theory, that if the ships bottom, could be replaced by air, it could reduce the drag ("The History of Hovercraft "). The Germans, created a Do-X flying boat, which proved that Thornycraft's theory was more realistic("The History of Hovercraft "). Even though, the boat's fuel consumption was through the roof, the Do-X Flying boat was a modern marvel back then. The boat could seat up to 150 people, the engine tended to overheat, but the boat could make it across the world with a few stops("The History of Hovercraft "). When the boat was landed in New York, the Germans were given a water-cooling engine, so the overheating problem would be diminished. The Germans used this boat to drop bombs during wars, to drop bombs, which was a great advantage("The History of Hovercraft "). ======

The first Hovercraft was built by Emanuel Swedenborg from Sweden ("The History of Hovercrafts"). The Hovercraft looked like an upside-down boat, the driver has to force air under the vessel, making the Hovercraft lift up("The History of Hovercrafts"). There was a Hovercraft company created after World War 1. Christopher Cockrell, was known as the Father of the Modern Hovercraft. He created the basic design of the Hovercraft, which is still used today("The History of Hovercrafts"). The vehicle had an empty box under it, with rubber skirting to seal it to the ground. Air is forced into the box, lifting the vehicle off the ground. Christopher also created the name "Hovercraft" for his vehicle, and let everyone know it was his("The History of Hovercrafts"). Saunders Roe, created the first man-carrying hovercraft, in 1959. Known as the SR-N1("The History of Hovercrafts"). A Royal Navy officer who worked with Cockrell, discovered that a 'skirt' would help the craft's lift ("The History of Hovercrafts"). Which it did. The first hovercraft to carry more than just a few passengers, was the SR-N6, which carried 38 passengers. Two, modern day hovercrafts, still use the route that the SR-N6 was tested on, and these modern day crafts, carry 98 passengers. Doctor William Bertelsen needed a new way to transport his patients, so he decided to create new forms of the Hovercraft. He created many types of the Hovercraft, but he wasn't well known for the quality of the crafts ("The History of Hovercrafts"). ======

The Hovercraft is an amazing invention. It has helped everyone from, regular citizens, to the military. The Hovercraft has made a big impact on society by improving the time taken to transport people, and supplies, for less gas, and less drag. The Hovercraft can move on any surface, as long as the ground isn't too rigid. This little boat, is a great success and have helped everyone in some way.
