There is a 700 page book, with 450 pictures called 'On a Cushion of Air', (available on Amazon or The Book Depository3ysen and Kindle), which tells the story of Christopher Cockerell's discovery that heavy weights could be supported on a cushion of low pressure air, and the development of the hovercraft by those who were there, from the very early days through to the heyday of the giant 165-ton SRN.4, which crossed the English Channel starting in 1968 carrying 30 cars and 254 passengers at speeds in excess of 75 knots on a calm day. It was subsequently widened to carry 36 cars and 280 passengers with an A.U.W. of 200 tones and was later lengthened to an A.U.W of 325 tons and capable of carrying 55 cars and 424 passengers. The amazing point was that from 165 tons to 325 tons only 400 extra hp was required, although a bit of speed was sacrificed, proving conclusively that Christopher Cockerell's theory was sound.
Sadly, for economic reasons, the service came to an end on 1st October 2000. In total 6 SR.4s were built and the two remaining ones are in the Hovercraft Museum at Lee-on-Solent. See onacushionofair.com

A hovercraft (air-cushion vehicle, ACV) is a craft capable of traveling over relatively smooth surfaces supported by a cushion of slow moving, high-pressure air, ejected against the surface below, and contained within a "skirt." Hovercraft are used throughout the world as specialized transports. Because they are supported by a cushion of air, hovercraft are unique among 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.

In the world of crafts Air cushion vehicles (ACV) are fast catching up. Air cushion vehicle is a craft that travels on a layer of compressed air just above any kind of surface- land, water, ice etc. Their main area of applications are in military vehicles, helicopters and where transportation using wheeled or tracked vehicles are impossible. Air cushion vehicle (ACV) is a craft that travels on a layer of compressed air just above any kind of surface - land, water, ice, sand, mud etc. The compressed air serves as an invisible cushion that eliminates almost all friction between the vehicle and the surface. Air cushion vehicles are also known as Hovercraft. They can carry both passenger and freight. Some air cushion vehicles can travel as fast as 480 km per hour.In this seminar operations of ACV s are reviewed.
plz sent me de details of Hovercraft..so dat i can present it in my college as my final year seminars..plz do help me..
hi i want to know more about this please sent it to me as soon as possible
please send me full seminar report of this topic- air cushion vehicles
