A hovercraft (pl.: hovercraft [1]), also known as an air-cushion vehicle or ACV, [2] is an amphibious craft capable of travelling over land, water, mud, ice, and various other surfaces. Hovercraft use blowers to produce a large volume of air below the hull, or air cushion, that is slightly above atmospheric pressure. The pressure difference ...
Alternatively a hovercraft can be built from scratch. Many plans can be found online so all you need do is buy your materials. Generally, racing hovercraft are provided with a high-RPM motor fan at the backside of the hovercraft for the required thrust. The racing hovercraft's height is limited to provide it stability even at high speeds.
It is this principle of levitation upon which a hovercraft is based, and Christopher Cockerell set about applying his momentum curtain theory to hovercraft to increase their abilities in overcoming friction in travel. [1] [2] Levitating a vehicle above the ground/water to reduce its drag was not a new concept.
SR.N1. The Saunders-Roe SR.N1 (Saunders-Roe Nautical 1) was the first practical hovercraft.The concept has its origins in the work of British engineer and inventor Christopher Cockerell, who succeeded in convincing figures within the services and industry, including those within British manufacturer Saunders-Roe.

The M200G Neuera is a prototype of a flying saucer-style hovercraft, designed by aeronautics engineer Paul Moller. The vehicle is envisioned as a precursor to the Moller M400 Skycar. The M200G Volantor uses a system of eight computer-controlled fans to hover up to 10 feet (3 m) above the ground. [1]
During 2001, it was announced that the Indian Coast Guard had formed an agreement with Griffon Hoverwork to supply an initial batch of six 8000TD hovercraft, two of which were to be manufactured at GHL's boatyard in Southampton, England, while the remaining four craft were assembled from complete knocked-down kits (CKDs) supplied to the Indian company Garden Reach Shipbuilders & Engineers ...
The Saunders-Roe SR.N5 (or Warden class) was a medium-sized hovercraft which first flew in 1964. It has the distinction of being the first production-built hovercraft in the world. [2] A total of 14 SR.N5s were constructed.
In August 2010, the US Navy issued a Request For Proposals for a contract to design and build 72 SSCs. [9] The contract would be worth up to US$4 billion. [ 10 ] A contract for detailed design work and construction of the first test and training craft, was expected to be awarded in 2011.
