The British aircraft architect Saunders-Roe developed the aboriginal applied man-carrying hovercraft, the SR.N1, which agitated out several analysis programmes in 1959 to 1961 (the aboriginal accessible affirmation in 1959), including a cross-channel analysis run in July 1959 piloted by Peter ("Sheepy") Lamb, an ex-naval analysis pilot and the Chief Analysis Pilot at Saunders Roe. Christopher Cockerell was on board, and the flight took abode on the 50th ceremony of Louis Blériot's aboriginal aeriform crossing.11

The SR.N1 was powered by one (piston) engine, apprenticed by expelled air. Demonstrated at the Farnborough Airshow in 1960,11 it was apparent that this simple ability could backpack a amount of up to 12 Marines with their accessories as able-bodied as the pilot and co-pilot with alone a slight abridgement in hover acme proportional to the amount carried. The SR.N1 did not accept any skirt, application instead the borderline air assumption that Sir Christopher had patented. It was afterwards begin that the craft's hover acme was bigger by the accession of a brim of adjustable bolt or elastic about the aerial apparent to accommodate the air. The brim was an absolute apparatus fabricated by a Royal Navy officer, C.H. Latimer-Needham, who awash his abstraction to Westland (parent aggregation of Saunders-Roe), and who formed with Sir Christopher to advance the abstraction further.

The aboriginal passenger-carrying hovercraft to access account was the Vickers VA-3, which in the summer of 1962 agitated cartage consistently forth the arctic Wales Coast from Moreton, Merseyside, to Rhyl. It was powered by two turboprop aero-engines and apprenticed by propellers.citation needed

In Britain, the RNLI accomplish a baby agile of hovercraft lifeboats

The Hovertravel account amid the Isle of Wight and acreage England is currently the alone accessible hovercraft account in the United Kingdom

During the 1960s Saunders-Roe developed several beyond designs which could backpack passengers, including the SR.N2, which operated beyond the Solent in 1962 and afterwards the SR.N6, which operated beyond the Solent from Southsea to Ryde on the Isle of Wight for abounding years. In 1963 the SR.N2 was acclimated on an alpha account amid Weston-super-Mare and Penarth beneath the advocacy of P & A Campbell, the paddle steamer operators.

Operations by Hovertravel commenced on July 24, 1965 application the SR.N6 which agitated just 38 passengers.11 Two 98 bench AP1-88 hovercraft were alien on this avenue in 1983, and in 2007 these were abutting by the aboriginal 130 seater BHT130 craft. The AP1-88 and the BHT130 were notable as they were abundantly congenital by Hoverwork application shipbuilding techniques/materials (i.e. anchored aluminium anatomy and agent engines) rather than the aircraft techniques acclimated to body the beforehand ability congenital by Saunders-Roe/British Hovercraft Corporation. Over 20 actor cartage had acclimated the account as of 2004 – the account is still operating (2010) and is by far the longest, continuously operated hovercraft service.

In 1966, two cross-channel commuter hovercraft casework were inaugurated application SR.N6 hovercraft. Hoverlloyd ran casework from Ramsgate Harbour, England, to Calais, France, and Townsend Ferriescitation needed aswell started a account to Calais from Dover, which was anon abolished by that of Seaspeed.

As able-bodied as Saunders-Roe and Vickers (which accumulated in 1966 to anatomy the British Hovercraft Corporation (BHC)), added bartering ability were developed during the 1960s in the UK by Cushioncraft (part of the Britten-Norman Group) and Hovermarine based at Woolston (the closing getting 'Sidewall Hovercraft', breadth the abandon of the bark projected down into the baptize to allurement the beanbag of air with 'normal' hovercraft skirts at the bow and stern). One of these models, the HM-2, was acclimated by Red Funnel amid Southampton (near the Woolston Floating Bridge) and Cowes.12

The world's aboriginal car-carrying hovercraft was fabricated in 1968, the BHC Mountbatten chic (SR.N4) models, anniversary powered by four Rolls-Royce Proteus gas agent engines. These were both acclimated by battling operators Hoverlloyd and Seaspeed to accomplish approved car and commuter accustomed casework beyond the English Channel. Hoverlloyd operated from Ramsgate, breadth a appropriate hoverport had been congenital at Pegwell Bay, to Calais. Seaspeed operated from Dover, England, to Calais and Boulogne in France. The aboriginal SR.N4 had a accommodation of 254 cartage and 30 cars, and a top acceleration of 83 kn (154 km/h). The Approach bridge took about 30 account and was run rather like an airline with flight numbers. The afterwards SR.N4 Mk.III had a accommodation of 418 cartage and 60 cars to the Isle of Wight . These were afterwards abutting by the French-built SEDAM N500 Naviplane with a accommodation of 385 cartage and 45 cars; alone one entered account and was acclimated intermittently for a few years on the cross-channel account until alternate to SNCF in 1983. The account accomplished in 2000 afterwards 32 years, due to antagonism with acceptable ferries, catamaran, the dematerialization of duty-free arcade aural the EU and the advancing age of the SR.N4 hovercraft and the aperture of the Approach Tunnel.

The bartering success of hovercraft suffered from accelerated rises in ammunition prices during the backward 1960s and 1970s afterward battle in the Middle East. Addition over-water cars such as wave-piercing catamarans (marketed as the SeaCat in the UK until 2005) use beneath ammunition and can accomplish a lot of of the hovercraft's abyssal tasks. Although developed abroad in the apple for both civilian and aggressive purposes, except for the Solent Ryde to Southsea crossing, hovercraft abolished from the bank of Britain until a ambit of Griffon Hovercraft were bought by the Royal National Lifeboat Institution.

editCivilian non-commercial

In Finland, baby hovercraft are broadly acclimated in amphibian accomplishment and during the rasputitsa ("mud season") as archipelago communication vehicles. In England, hovercraft of the Burnham-on-Sea Breadth Accomplishment Boat (BARB) are acclimated to accomplishment humans from blubbery mud in Bridgwater Bay. Avon Blaze and Accomplishment Account became the aboriginal Local Authority blaze account in the UK to accomplish a hovercraft. It is acclimated to accomplishment humans from blubbery mud in the Weston-super-Mare breadth and during times of civil flooding. A Griffon accomplishment Hovercraft has been in use for a amount of years with the Airport Blaze Account at Dundee Airport in Scotland. It is acclimated in the accident of an aircraft ditching in the Tay estuary. Numerous blaze departments about the U.S./Canadian Great Lakes accomplish hovercraft for baptize and ice rescues, generally of ice fisherman alone if ice breach off from shore.

In October 2008 The Red Cross commenced a flood-rescue account hovercraft based in Inverness, Scotland.13 Gloucestershire Blaze and Accomplishment Account accustomed two flood-rescue hovercraft donated by Severn Trent Baptize afterward the 2007 UK floods.14

Since 2006 hovercraft accept been acclimated in aid in Madagascar by HoverAid, an all-embracing NGO who use the hovercraft to ability the a lot of limited places on the island.15 The Scandinavian airline SAS acclimated to allotment an AP1-88 hovercraft for approved cartage amid Copenhagen Airport, Denmark, and the SAS Hovercraft Terminal in Malmö, Sweden.

In 1998, the US Postal Account began application the British congenital Hoverwork AP1-88 to booty mail, freight, and cartage from Bethel, Alaska, to and from eight baby villages forth the Kuskokwim River. Bethel is far removed from the Alaska alley system, appropriately authoritative the hovercraft an adorable addition to the air based supply methods acclimated above-mentioned to addition of the hovercraft service. Hovercraft account is abeyant for several weeks anniversary year while the river is alpha to benumb to abbreviate accident to the river ice surface. The hovercraft is able to accomplish during the freeze-up period; however, this could potentially breach the ice and actualize hazards for villagers application their snowmobiles forth the river during the aboriginal winter.

In 2006 Kvichak Abyssal Industries of Seattle USA built, beneath license, a cargo/passenger adaptation of the Hoverwork BHT130. Appointed 'Suna-X', it is acclimated as a top acceleration bear for up to 47 cartage and 47,500 pounds of bales confined the limited Alaskan villages of King Cove and Cold Bay.

An alpha account was operated in Scotland beyond the Firth of Forth (between Kirkcaldy and Portobello, Edinburgh), from 16 to 28 July 2007. Marketed as Forthfast, the account acclimated a ability accountant from Hovertravel and accomplished an 85% commuter amount factor. As of 2009 the achievability of establishing a abiding account is still beneath consideration.16dead link

Since the approach routes alone hovercraft, and awaiting any reintroduction on the Scottish route, the United Kingdom's alone accessible hovercraft account is that operated by Hovertravel amid Southsea (Portsmouth) and Ryde on the Isle of Wight.

From the 1960s, several bartering curve were operated in Japan, afterwards abundant success. In Japan the endure bartering band had affiliated Ōita Airport and axial Ōita but was shut down in October 2009.

A U.S. Navy Landing Ability Air Cushion, an archetype of a aggressive hovercraft

Hovercraft are still bogus in the UK abreast to breadth they were aboriginal conceived and activated and the Isle Of Wight. They can aswell be accountant for a avant-garde array of uses including inspections of bank bed adopted wind farms and VIP or commuter use. A archetypal barge would be a Tiger IV or a Griffon. They are light, fast, alley carriageable and absolute adjustable with the altered affection of minimising accident to environments.

First applications of the hovercraft in aggressive use was with the SR.N1 through SR.N6 ability congenital by Saunders-Roe in the Isle of Wight in the UK and acclimated by the UK collective forces. To analysis the use of the hovercraft in aggressive applications the UK set up the Interservice Hovercraft Trials Assemblage (IHTU) abject at Lee-on-the-Solent (now the website of the Hovercraft Museum). This assemblage agitated out trials on the SR.N1 from Mk1 through Mk5 as able-bodied as testing the SR.N2, SR.N3, SR.N5 and SR.N6 craft. Currently the Royal Marines use the Griffon 2000 TDX Chic ACV as an operational craft. The 2000 was deployed by the UK in Iraq.

In the US, during the 1960s, Bell licenced and awash the Saunders-Roe SR.N5 as the Bell SK-5. They were deployed on balloon to the Vietnam War by the United States Navy as PACV convoying ability in the Mekong Basin breadth their advancement and acceleration was unique. This was acclimated in both the UK SR.N5 arced accouter agreement and afterwards with adapted collapsed deck, gun turret and armament launcher appointed the 9255 PACV. The United States Army aswell experimented with the use of SR.N5 hovercraft in Vietnam. Three hovercraft with the collapsed accouter agreement were deployed to Dong Tam in the Mekong basin arena and afterwards to Ben Luc. They saw activity primarily in the Plain of Reeds. One was destroyed in aboriginal 1970 and addition in August of that aforementioned year afterwards which the assemblage was disbanded. The alone absolute U.S. Army SR.N5 hovercraft is currently on affectation in the Army Carriage Museum in Virginia. Experience led to the proposed Bell SK-10 which was the base for the LCAC-class air-cushioned landing ability now deployed by the U.S. and Japanese Navy.

The Soviet Union was the world's better developer of aggressive hovercraft. Their designs ambit from the baby Czilim chic ACV, commensurable to the SR.N6, to the aberrant Zubr chic LCAC, the world's better hovercraft. The Soviet Union was aswell one of the aboriginal nations to use a hovercraft, the Bora, as a guided missile corvette, admitting this ability bedevilled rigid, non-inflatable sides. With the abatement of the Soviet Union a lot of Soviet aggressive hovercraft fell into decay and disrepair. Alone afresh has the avant-garde Russian Navy amorphous architecture new classes of aggressive hovercraft.

The Finnish Navy advised an alpha missile advance hovercraft class, Tuuli chic hovercraft, in the backward 1990s. The ancestor of the class, Tuuli, was commissioned in 2000. It accepted an acutely acknowledged architecture for a bank fast advance craft, but due to budgetary affidavit and doctrinal change in the Navy, the hovercraft was anon withdrawn.

The Hellenic Navy operates four Russian-designed Zubr chic LCAC. This is the world’s better aggressive air-cushioned landing craft.

The People's Army Navy of China operates the Jingsah II chic LCAC. This troop and accessories accustomed hovercraft is almost the Chinese agnate of the U.S. Navy LCAC.

editRecreational/sport

Coastal Cruising

Small commercially manufactured, kit or plan-built hovercraft are added getting acclimated for recreational purposes such as civil antagonism and canoeing on civil lakes and rivers, littoral areas, estuaries and inshore littoral waters.17

The Hovercraft Canoeing Club 18 is committed to encouraging, acknowledging and developing the safe & accommodating operation of recreational canoeing hovercraft. It organises training, breezy hover-events, and offers world-class hovercraft architecture tools, admonition on safe operation, affiliate discounts and ability insurance. It has an alive and advisory club affiliate forum.

The Hovercraft Club of Great Britain, founded in 1966, consistently organizes civil and littoral hovercraft chase contest at assorted venues beyond the United Kingdom.19

Single seater antagonism hovercraft

In August 2010 the Hovercraft Club of Great Britain hosted the Apple Hovercraft Championships at Towcester Racecourse 20 The Apple Hovercraft Championships are run beneath the advocacy of the Apple Hovercraft Federation.21 Agnate contest are aswell captivated in Europe and the US.2223

editHoverbarge

A absolute account of air beanbag cars in affective abundant endless over difficult terrain, such as swamps, was disregarded by the activity of the British Government allotment to advance accelerated hovercraft. It was not until the aboriginal 1970s that the technology was acclimated for affective a modular abyssal barge with a dragline on lath for use over bendable reclaimed land.

Mackace (Mackley Air Beanbag Equipment), now accepted as Hovertrans, produced a amount of acknowledged Hoverbarges, such as the 250 ton burden “Sea Pearl” which operated in Abu Dhabi and the accompanying 160 ton burden "Yukon Princesses" which alien trucks beyond the Yukon river to aid the activity build. Hoverbarges are still in operation today. In 2006, Hovertrans (formed by the aboriginal managers of Mackace) launched a 330 ton burden conduct barge in the swamps of Suriname.

The Hoverbarge technology is somewhat altered from accelerated hovercraft, which has commonly been complete application aircraft technology. The antecedent abstraction of the air beanbag barge has consistently been to accommodate a low-tech amphibian band-aid for accessing architecture sites application archetypal accessories begin in this area, such as agent engines, ventilating fans, winches and abyssal equipment. The amount to move a 200 ton burden ACV barge at 5 kn (9.3 km/h) would alone be 5 tons. The brim and air administration architecture on the accelerated ability afresh is added circuitous as they accept to cope with the air beanbag getting done out by a beachcomber and beachcomber impact. The apathetic acceleration and ample address alcove of the hover barge in fact helps abate the aftereffect of beachcomber activity giving a absolute bland ride.

editHovertrains

Several attempts accept been fabricated to accept air beanbag technology for use in anchored clue systems, in adjustment to advance the lower frictional armament for carrying top speeds. The a lot of avant-garde archetype of this was the Aérotrain, an alpha top acceleration hovertrain congenital and operated in France amid 1965 and 1977. The activity was alone in 1977 due to abridgement of funding, the afterlife of its advance architect and the acceptance of TGV by the French government as its accelerated arena carriage solution.

A analysis clue for a tracked hovercraft arrangement was congenital at Earith abreast Cambridge, England. It ran southwest from Sutton Gault, sandwiched amid the Old Bedford River and the abate Counter Drain to the west. Careful assay of the website will still acknowledge traces of the accurate piers acclimated to abutment the structure. The absolute vehicle, RTV31, is preserved at Railworld in Peterborough24 and can be apparent from trains, just south west of Peterborough railway station. The car accomplished 104 mph (167 km/h) on 7 February 197325 but the activity was annulled a anniversary later. The activity was managed by Tracked Hovercraft Ltd., with Denys Bliss as Director in the aboriginal 1970s, alone to be axed by the Aerospace Minister, Michael Heseltine. Records of this activity are accessible from the accord and affidavit of Sir Harry Legge-Bourke, MP at Leeds University Library.26 Heseltine was accused by Airey Neave and others of ambiguous the House of Commons if he declared that the government was still because giving banking abutment to the Hovertrain, if the accommodation to cull the bung had already been taken by the Cabinet.

Despite able aboriginal results, the Cambridge activity was alone in 1973 due to banking constraints, but locations of the activity were best up by the engineering close Alfred McAlpine, alone to be assuredly alone in the mid 1980s. The Tracked Hovercraft activity and Professor Laithwaite's Maglev alternation arrangement were contemporaneous, and there was acute antagonism amid the two -to-be British systems for allotment and credibility.

At the added end of the acceleration spectrum, the Dorfbahn Serfaus has been in connected operation back 1985. This is an abnormal underground air beanbag funicular accelerated alteration system, anchored in the Austrian ski resort of Serfaus. Alone 1,280 m (4,200 ft) long, the band alcove a best acceleration of 25 mph (40 km/h). A agnate arrangement aswell exists in Narita All-embracing Airport abreast Tokyo, Japan.

In the backward 1960s and aboriginal 1970s the U.S. Administration of Transport's Urban Mass Alteration Administration adjourned several hovertrain projects which were accepted as Tracked Air Beanbag Cars or TACVs. They were aswell accepted as Aerotrains back one of the builders had a licence from Bertin's Aerotrain company. Three abstracted projects were funded. Research and development was agitated out by Rohr, Inc., Garrett AiResearch and Grumman. The UMTA congenital an all-encompassing analysis website in Pueblo, Colorado, with altered types of advance for the altered technologies acclimated by the ancestor contractors. They managed to body prototypes and do a few analysis runs afore the allotment was cut.

editNon-transportation

The Hoover Constellation was a all-around canister-type exhaustion cleaner notable for its abridgement of wheels. Floating on a beanbag of air, it was a calm hovercraft. They were not abnormally acceptable as exhaustion cleaners as the air artifice from beneath the beanbag blew uncollected dust in all directions, nor as hovercraft as their abridgement of a brim meant that they alone hovered finer over a bland surface. Despite this, aboriginal Constellations are approved collectibles today.

The Flymo is an air-cushion backyard mower which uses a fan on the cutter brand to accommodate lift. This allows it to be confused in any direction, and provides double-duty as a mulcher.
