Further modifications, especially the addition of pointed nose and stern areas, produced the Mk IV. The standard plural of hovercraft is hovercraft (in the same manner that aircraft is both singular and plural). Arm it to the teeth with machine guns, lasers, and rockets. Over time, this design evolved into individual extensions over the bottom of the slots in the skirt, known as "fingers". In this role, small hovercraft can offer a more entertaining alternative to the usual small boat and can be a rival for the jet-ski. [34], In the US, during the 1960s, Bell licensed and sold the Saunders-Roe SR.N5 as the Bell SK-5. This level of interest has naturally led to a hovercraft rental sector and numerous manufacturers of small, ready built designs of personal hovercraft to serve the need.[48]. Latimer-Needham, who sold his idea to Westland (by then the parent of Saunders-Roe's helicopter and hovercraft interests), and who worked with Cockerell to develop the idea further. These designs competed with maglev systems in the high-speed arena, where their primary advantage was the very "low tech" tracks they needed. See Neoteric Hovercraft in action @FDIC 2018! [10][11], During World War II, an American engineer, Charles Fletcher, invented a walled air cushion vehicle, the Glidemobile. After the Cambridge project was abandoned due to financial constraints, parts of the project were picked up by the engineering firm Alfred McAlpine, and abandoned in the mid-1980s. In England, hovercraft of the Burnham-on-Sea Area Rescue Boat (BARB) are used to rescue people from thick mud in Bridgwater Bay. With the fall of the Soviet Union most Soviet military hovercraft fell into disuse and disrepair. Because the project was classified by the U.S. government, Fletcher could not file a patent.[12]. A further upgrade with the Armstrong Siddeley Viper produced the Mk III. This is an unusual underground air cushion funicular rapid transit system, situated in the Austrian ski resort of Serfaus. The initial concept of the air cushion barge has always been to provide a low-tech amphibious solution for accessing construction sites using typical equipment found in this area, such as diesel engines, ventilating fans, winches and marine equipment. The Hovercraft Cruising Club[42] supports the use of hovercraft for cruising in coastal and inland waterways, lakes and lochs. In normal operation this extra airflow was directed rearward for forward thrust, and blew over two large vertical rudders that provided directional control. [46][47], Apart from the craft designed as "racing hovercraft", which are often only suitable for racing, there is another form of small personal hovercraft for leisure use, often referred to as cruising hovercraft, capable of carrying up to four people.

The hovercraft is able to operate during the freeze-up period; however, this could potentially break the ice and create hazards for villagers using their snowmobiles along the river during the early winter. He demonstrated the model flying over many Whitehall carpets in front of various government experts and ministers, and the design was subsequently put on the secret list. The design featured an engine mounted to blow from the front of the craft into a space below it, combining both lift and propulsion. And right now you can watch one in action on the world’s 4th most dangerous swiftwater in China. By the early 1970s, the basic concept had been well developed, and the hovercraft had found a number of niche roles where its combination of features were advantageous. The low pull force enabled a Boeing 107 helicopter to pull a hoverbarge across snow, ice and water in 1982.[50][51]. The actual vehicle, RTV31, is preserved at Railworld in Peterborough[52] and can be seen from trains, just south west of Peterborough railway station. Only when in motion could the craft trap air under the front, increasing lift. Lacking a skirt, the pads had to remain very close to the running surface. At the other end of the speed spectrum, the Dorfbahn Serfaus has been in continuous operation since 1985. From the 1960s, several commercial lines were operated in Japan, without much success. Hovercraft used to ply between the Gateway of India in Mumbai and CBD Belapur and Vashi in Navi Mumbai between 1994 and 1999, but the services were subsequently stopped due to the lack of sufficient water transport infrastructure. The People's Army Navy of China operates the Jingsah II class LCAC. [30] This unit carried out trials on the SR.N1 from Mk1 through Mk5 as well as testing the SR.N2, SR.N3, SR.N5 and SR.N6 craft. The Soviet Union was the world's largest developer of military hovercraft. Small craft, such as the SR.N6, usually have one engine with the drive split through a gearbox. The Landing Craft Air Cushion (LCAC) is a class of air-cushion vehicle (hovercraft) used as landing craft by the United States Navy’s Assault Craft Units and the Japan Maritime Self-Defense Force (JMSDF). The Hellenic Navy operates four Russian-designed Zubr class LCAC. It is used to rescue people from thick mud in the Weston-super-Mare area and during times of inland flooding. The first application of the hovercraft for military use was by the British Armed Forces, using hovercraft built by Saunders-Roe. UMTA built an extensive test site in Pueblo, Colorado, with different types of tracks for the different technologies used by the prototype contractors.
