AP1-88
The British Hovercraft Corporation AP1-88 is a medium-size hovercraft. In a civil configuration, the hovercraft can seat a maximum of 101 passengers, while as a troop carrier, it can transport up to 90 troops. When operated as a military logistics vehicle, the AP1-88 can carry a pair of Land Rovers, a Bv202 tracked vehicle and trailer unit or up to roughly 10 tons (10,000 kg) of cargo. The AP1-88 had several advantages over earlier hovercraft in terms of its increased fuel economy and reduced noise output, which is principally due to the decision to power the craft using several diesel engines instead of using gas turbine engines, the latter having been used on earlier craft. From 1983 to 2018, AP1-88-100s were operated in Britain by Hovertravel on a route from Southsea in Hampshire to Ryde on the Isle of Wight. Outside of the United Kingdom, vehicles of the type have also been operated in a various of locations around the world, including Norway, Australia, China, and Taiw ...

Hovertravel
Hovertravel is a ferry company operating from Southsea, Portsmouth to Ryde, Isle of Wight, UK. It is the only passenger hovercraft company currently operating in Britain since Hoverspeed stopped using its craft in favour of catamarans and subsequently ceased all ferry operations in 2005. Hovertravel is now the world's oldest hovercraft operator, and this service is believed to be unique in western Europe. Hovertravel has claimed that it is the world's only commercial passenger hovercraft service. The operator's principal service operates between Southsea Common on the English mainland and Ryde Transport Interchange on the Isle of Wight: the crossing time of less than 10 minutes makes it the fastest route across The Solent from land to land. This service commenced operations in 1965, Hovertravel currently operates two 12000TD hovercraft on a single route between Ryde and Southsea. Additionally, Hovertravel has frequently operated other routes throughout the United Kingdom, typ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
British Hovercraft Corporation
British Hovercraft Corporation (BHC) was a British hovercraft manufacturer that designed and produced multiple types of vehicles for both commercial and civil purposes. Created with the intention of producing viable commercial hovercraft in March 1966, BHC was the result of an corporate merger between the Saunders-Roe division of Westland Aircraft and Vickers Supermarine's hovercraft interests. None of the Vickers hovercraft designs reached quantity production, manufacturing efforts being centered upon Saunders-Roe's existing portfolio. Perhaps the most high-profile vehicle produced by BHC was the large SR.N4 ''Mountbatten'' class hovercraft; it was the largest civil-orientated hovercraft to ever be put into service; several were completed and used in revenue services across the English Channel for multiple decades. Later on, the BHC developed their own newer hovercraft designs, such as the military-oriented BH.7 ''Wellington'' class and the medium-size diesel-powered British Ho ...

Hovercraft
A hovercraft, also known as an air-cushion vehicle or ACV, is an amphibious Craft (vehicle), craft capable of travelling over land, water, mud, ice, and 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 between the higher pressure air below the hull and lower pressure ambient air above it produces lift, which causes the hull to float above the running surface. For stability reasons, the air is typically blown through slots or holes around the outside of a disk- or oval-shaped platform, giving most hovercraft a characteristic rounded-rectangle shape. The first practical design for hovercraft was derived from a British invention in the 1950s. They are now used throughout the world as specialised transports in disaster relief, coastguard, military and survey applications, as well as for sport or passenger service. Very large versions have been used to t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Saunders-Roe
Saunders-Roe Limited, also known as Saro, was a British aero- and marine-engineering company based at Columbine Works, East Cowes, Isle of Wight. History The name was adopted in 1929 after Alliott Verdon Roe (see Avro) and John Lord took a controlling interest in the aircraft and boat-builders S. E. Saunders. Prior to this (excepting for the Sopwith/Saunders Bat Boat) the products were Saunders, the A4 Medina for example dating from 1926. Sam Saunders the founder developed the Consuta material used in marine and aviation craft. The Saunders-Roe interest in aviation didn’t prevent the firm from continuing with the boatbuilding activities associated with S. E. Saunders Ltd Saunders Roe concentrated on producing flying-boats, but none were produced in very large quantities – the longest run being 31 Londons. They also produced hulls for the Blackburn Bluebird. During the Second World War Saro manufactured Supermarine Walrus and Supermarine Sea Otters. Their works at ...

British Technology Group
BTG Limited is an international specialist healthcare company that is developing and commercialising products targeting critical care, cancer and other disorders. The current name was adopted when the British Technology Group changed its name on 27 May 1998. BTG was a constituent of the FTSE 250 Index until it was acquired by Boston Scientific in August 2019. History In 1948, the National Research Development Corporation was formed with the purpose of commercialising innovations that arose from public funded research. This was complemented in November 1975 by the establishment of the National Enterprise Board to implement the then-Government's policy of moving public sector industry into commercial private enterprise. These two organisations were merged by the Government in 1981 to form a new, non-statutory body called the British Technology Group. It acted principally to license and commercialise the use of publicly funded developments. The Group was put onto a statutory footing ...

Sound Barrier
The sound barrier or sonic barrier is the large increase in aerodynamic drag and other undesirable effects experienced by an aircraft or other object when it approaches the speed of sound. When aircraft first approached the speed of sound, these effects were seen as constituting a barrier, making faster speeds very difficult or impossible. The term ''sound barrier'' is still sometimes used today to refer to aircraft approaching Supersonic speed, supersonic flight in this high drag regime. Flying faster than sound produces a sonic boom. In dry air at 20 °C (68 °F), the speed of sound is 343 metres per second (about 767 mph, 1234 km/h or 1,125 ft/s). The term came into use during World War II when pilots of high-speed fighter aircraft experienced the effects of compressibility, a number of adverse aerodynamic effects that deterred further acceleration, seemingly impeding flight at speeds close to the speed of sound. These difficulties represented a bar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Helicopter
A helicopter is a type of rotorcraft in which lift and thrust are supplied by horizontally spinning rotors. This allows the helicopter to take off and land vertically, to hover, and to fly forward, backward and laterally. These attributes allow helicopters to be used in congested or isolated areas where fixed-wing aircraft and many forms of STOL (Short TakeOff and Landing) or STOVL (Short TakeOff and Vertical Landing) aircraft cannot perform without a runway. In 1942, the Sikorsky R-4 became the first helicopter to reach full-scale production.Munson 1968.Hirschberg, Michael J. and David K. Dailey"Sikorsky". ''US and Russian Helicopter Development in the 20th Century'', American Helicopter Society, International. 7 July 2000. Although most earlier designs used more than one main rotor, the configuration of a single main rotor accompanied by a vertical anti-torque tail rotor (i.e. unicopter, not to be confused with the single-blade monocopter) has become the most comm ...

Turboshaft
A turboshaft engine is a form of gas turbine that is optimized to produce shaftpower rather than jet thrust. In concept, turboshaft engines are very similar to turbojets, with additional turbine expansion to extract heat energy from the exhaust and convert it into output shaft power. They are even more similar to turboprops, with only minor differences, and a single engine is often sold in both forms. Turboshaft engines are commonly used in applications that require a sustained high power output, high reliability, small size, and light weight. These include helicopters, auxiliary power units, boats and ships, tanks, hovercraft, and stationary equipment. Overview A turboshaft engine may be made up of two major parts assemblies: the 'gas generator' and the 'power section'. The gas generator consists of the compressor, combustion chambers with ignitors and fuel nozzles, and one or more stages of turbine. The power section consists of additional stages of turbines, a gear reduction ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Taiwan
Taiwan, officially the Republic of China (ROC), is a country in East Asia, at the junction of the East and South China Seas in the northwestern Pacific Ocean, with the People's Republic of China (PRC) to the northwest, Japan to the northeast, and the Philippines to the south. The territories controlled by the ROC consist of 168 islands, with a combined area of . The main island of Taiwan, also known as ''Formosa'', has an area of , with mountain ranges dominating the eastern two-thirds and plains in the western third, where its highly urbanised population is concentrated. The capital, Taipei, forms along with New Taipei City and Keelung the largest metropolitan area of Taiwan. Other major cities include Taoyuan, Taichung, Tainan, and Kaohsiung. With around 23.9 million inhabitants, Taiwan is among the most densely populated countries in the world. Taiwan has been settled for at least 25,000 years. Ancestors of Taiwanese indigenous peoples settled the isla ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
1973 Oil Crisis
The 1973 oil crisis or first oil crisis began in October 1973 when the members of the Organization of Arab Petroleum Exporting Countries (OAPEC), led by Saudi Arabia, proclaimed an oil embargo. The embargo was targeted at nations that had supported Israel during the Yom Kippur War. The initial nations targeted were Canada, Japan, the Netherlands, the United Kingdom and the United States, though the embargo also later extended to Portugal, Rhodesia and South Africa. By the end of the embargo in March 1974, the price of oil had risen nearly 300%, from US to nearly globally; US prices were significantly higher. The embargo caused an oil crisis, or "shock", with many short- and long-term effects on global politics and the global economy. It was later called the "first oil shock", followed by the 1979 oil crisis, termed the "second oil shock".
