    A hover craft is a vehicle that you stand on. It floats in the air. Hovercrafts are used throughout the world as specialized transports. They can also be used after a natural disaster for emergency purposes. Because they are supported by a cushion of air, hovercraft are unique among all other forms of ground transportation in their ability to travel equally well over land, ice, and water. Small hovercraft are used for sport or passenger service, while giant hovercraft have civilian and military applications, and are used to transport cars, tanks, and large equipment in hostile environments and terrain.

    Background The Hovercraft was invented in 1952 by the British inventor Sir Christopher Cockerel, who was knighted for his services to engineering in 1969. By simple experiments involving a vacuum cleaner motor and two cylindrical cans he proved the workable principle of a vehicle suspended on a cushion of air blown out under pressure, making the vehicle easily mobile over any surface. This would enable it to operate over soft mud, water, and marshes and swamps as well as on firm ground. Many people worked on the idea of the hovercraft on over the years. | Advantages of Hovercraft A well-designed hovercraft is superior to a boat because it has less drag and requires less horsepower to operate. A hovercraft is 100% more fuel-efficient than a boat with similar capacity or size. * Rising fuel prices and shortages are making the hovercraft a desirable form of transportation. * Hovercraft ride much smoother than boats because they travel over the surface of the water, not through it. * Hovercrafts eliminate the need to climb in and out at crowded docks or piers * Able to park almost anywhere and operate from unprepared areas * Travel over any surface. Negligible noise levels: About the same as a truck or high-speed boat * Hovercraft can operate over land, shallow water, reefs, ice and mudflats, beaches, river-deltas and dry riverbeds, covering territory previously designated unreachable. * Access to 75% of littoral instead of only 5% with conventional vessels * High Speed: Cruise at fill payload at speeds of 25 –36 knots * Low initial costs: Similar price to conventional boats of same speed and payload Services Provide by Hovercraft

    A partial listing of present uses includes: 1. Rescue work on swift water, ice, snow, mud flats, and deserts, in wetlands, shallow water, swamps, bogs, marshes and floodwaters. 2. Military services: Assault vehicles and transporting troops. 3. Heavy load movement across difficult surfaces. 4. Agricultural spraying; cranberry, rice and pecan farming. 5. Transportation or “island-hopping”. 6. Exploring the vast number of shallow and narrow waterways that cannot be reached by boat. 7. Oil spill clean up.

    Factors to be considered during the purchase of Hovercraft There are number of point to consider when purchasing a small hovercraft. However decision based on cost comparison alone is not recommended, as seriously safety factors need to taken into consideration. 1. Race craft focus on speed so it must be lightweight. 2. Self build built on low cost so occasionally compromise safety. 3. Leisure craft focus on safety and reliability, for salt water use. 4. Check warranty, Engine is new, standard, supplied with full documentation. . Hovercraft flotation, Hovercraft flotation is very important factor if you plan to ride hovercraft on open waters or rapids, or if you plan to use hovercraft as fishing boat, or hunting airboat in swamp 6. Hump speed time, Hump speed is time, that is necessary to beat the hump barrier. 7. Do not forget to check the components of your hovercraft boat especially the brakes. Working Mechanism of Hovercraft Parts 1)  Lifting fan: Usually a centrifugal fan is preferred.

    When rotated air is sucked into the center hole, it is coupled via a gearbox and connected to the engine 2) Thrust propellers: An aircraft type propeller with variable type pitch blades. Diameter ranges from nine feet to nineteen feet. In bigger crafts the propellers are rotated while in smaller ones, rudders are used. 3)  Skirt: Flexible strip which is fitted below the bottom edges of the plenum chamber. Skirt design is the most sensitive design parameter as it protects the craft and helps to lift it even higher.
