Amphibious Aircraft
An amphibious aircraft, or amphibian, is an aircraft that can Takeoff, take off and Landing, land on both solid ground and water. These aircraft are typically Fixed-wing aircraft, fixed-wing, though Amphibious helicopter, amphibious helicopters do exist as well. Fixed-wing amphibious aircraft are seaplanes (flying boats and floatplanes) which are equipped with Landing gear, retractable wheels, at the expense of extra weight and complexity, plus diminished range and fuel economy compared with planes designed specifically for land-only or water-only operation. Design Floatplanes often have floats that are interchangeable with wheeled landing gear (thereby producing a conventional land-based aircraft). However, in cases where this is not practical, amphibious floatplanes, such as the amphibious version of the de Havilland Canada DHC-3 Otter, DHC Otter, incorporate retractable wheels within their floats. Some amphibians are fitted with reinforced keels which act as skis, allowing ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dornier Seastar
The Dornier Seastar is a turboprop-powered amphibious aircraft built largely of composite materials. Developed by of Germany, it first flew in 1984. The design is owned by Claudius Jr's son, Conrado, who founded Dornier Seawings AG (now Dornier Seawings) to continue work on the project after two previous firms, Claudius Dornier Aircraft and Dornier Composite Aircraft, both went into bankruptcy. Development of the aircraft was put on hold without any production Seastars being completed in 1991. Multiple attempts to put the Seastar into production, often as a joint venture with other aerospace companies, were made throughout the 1990s and early 2000s. However securing the necessary financing to proceed to the manufacturing phase proved challenging. After several false starts, in October 2009, Dornier Seawings announced that it was formally launching manufacturing of the type, although no aircraft were actually built. In November 2018 the company received US$170 million in funding ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Supermarine Walrus
The Supermarine Walrus is a British single-engine Amphibious aircraft, amphibious biplane designed by Supermarine's R. J. Mitchell. Primarily used as a maritime patrol aircraft, it was the first British Squadron (aviation), squadron-service aircraft to incorporate an Landing gear, undercarriage that was fully retractable, crew accommodation that was enclosed, and a fuselage completely made of metal. Supermarine originally named the type the Supermarine Seagull V, before changing it to the ''Walrus''. The type first flew in 1933, its design process had begun four years earlier as a private venture. It shared its general arrangement with that of the earlier Supermarine Seagull (1921), Supermarine Seagull. Having been designed to serve as a Surveillance aircraft, fleet spotter launched by aircraft catapult, catapult from cruisers or battleships, the aircraft was employed as a maritime patrol aircraft. Early aircraft had a metal hull for greater longevity in Tropics, tropical condi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Supermarine Seagull (1948)
The Supermarine Seagull was a British amphibious, military flying boat and the last to be built by the Supermarine company. Design started during the Second World War but it did not fly until three years after the war had ended and the project was cancelled without it being adopted for service. Development In October 1940, the British Air Ministry issued Specification S.12/40 to Supermarine and Fairey for a catapult-launched, amphibian, reconnaissance and spotter aircraft to replace the Supermarine Walrus and Supermarine Sea Otter.London 2003, p. 230. An order for three prototypes of Supermarine's aircraft was issued in March 1943. There was an interruption in design due to the necessity of moving the Supermarine design office, after the bombing of the facility at Woolston. Further delays were caused by the extensive wind tunnel testing that was needed and the change from a Rolls-Royce Merlin to the more powerful Rolls-Royce Griffon. Also, the design specification was chan ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Supermarine Seagull (1921)
The Supermarine Seagull was a flying boat produced by the British aircraft manufacturer Supermarine. It was developed by Supermarine's chief designer R.J. Mitchell from the experimental Supermarine Seal II. Development of the Seagull started during 1920. In June 1921 it was evaluated for military applications but was rejected, and so Supermarine developed the aircraft as a private venture. During February 1922, an initial order for two aircraft was placed by the Air Ministry; subsequent production of the Seagull is believed to have assisted Supermarine to survive during a period when the aircraft industry struggled to attract customers. The Seagull was used by the British Fleet Air Arm for gunnery spotting and reconnaissance duties. It was operated by the Royal Australian Air Force for similar purposes. During the early 1930s, when the type was being replaced by the more successful Supermarine Walrus, a number of Seagulls were re-used for civilian purposes. Background The ...

Vickers Viking
The Vickers Viking was a British single-engine amphibious aircraft designed for military use shortly after World War I. Later versions of the aircraft were known as the Vickers Vulture and Vickers Vanellus. Design and development Research on Vickers' first amphibious aircraft type began in December 1918 with tests of alternative fuselage/hull designs occurring in an experimental tank at St Albans in Hertfordshire, England. A prototype, registered G-EAOV, was a five-seat cabin biplane with a pusher propeller driven by a Rolls-Royce Falcon water-cooled V 12 engine. Sir John Alcock died taking this aircraft to the Paris exhibition on 18 December 1919, whilst trying to land at Côte d'Evrard, near Rouen, Normandy in foggy weather.Andrews and Morgan 1988, pp. 112–113. The next example, G-EASC, known as the Viking II, had a greater wing span and a 360 hp Rolls-Royce Eagle VIII motor. The Viking III machine, piloted by Captain Stan Cockerell, won first prize in the a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Bush Plane
A bush plane is a general aviation aircraft used to provide both scheduled and unscheduled passenger and flight services to remote, undeveloped areas, such as the Canadian north or bush, Alaskan tundra, the African bush, or savanna, Amazon rainforest and the Australian Outback. They are used where ground transportation infrastructure is inadequate or does not exist. Common traits A bush plane is defined by how it is used, and many different aircraft with different configurations have been so used over the years. However, experience has shown certain traits to be desirable (though not mandatory), especially on aircraft specifically designed as bush planes. * Undercarriage designed to be fitted with floats, skis or wheel/skis to permit operation from water or snow—primarily for Canadian, Alaskan and Russian use. * High wings ease loading and unloading, particularly from docks; improve downward visibility during flight; and increase clearance to reduce the potential for damage ...

Shin Meiwa US-2
The ShinMaywa US-2 is a large Japanese short takeoff and landing amphibious aircraft that employs boundary layer control technology for enhanced STOL and stall suppression performance. Manufactured by seaplane specialist ShinMaywa (formerly ''Shin Meiwa''), it was developed from the earlier Shin Meiwa US-1A seaplane, which was introduced during the 1970s. The ShinMaywa US-2 was developed on behalf of the Japan Maritime Self-Defense Force (JMSDF) as a 'like-for-like' replacement for its aging US-1A fleet. In Japanese service, it is operated in the air-sea rescue (ASR) role. The US-2 can also be used in other capacities, such as an aerial fire fighter, carrying 15 tonnes of water for this mission. Various overseas operators have held discussions on potential acquisitions of the type, including the Indian Navy and Indian Coast Guard. Other countries such as the United States, Indonesia, Thailand, and Greece have also shown interest in the US-2 for various purposes. Design and ...

Grumman HU-16 Albatross
The Grumman HU-16 Albatross is a large, twin-radial engined amphibious flying boat that was used by the United States Air Force (USAF), the U.S. Navy (USN), the U.S. Coast Guard (USCG), and the Royal Canadian Air Force primarily as a search and rescue (SAR) aircraft. Originally designated as the SA-16 for the USAF and the JR2F-1 and UF-1 for the USN and USCG, it was redesignated as the HU-16 in 1962. Design and development An improvement of the design of the Grumman Mallard, the Albatross was developed to land in open-ocean situations to accomplish rescues. Its deep-V hull cross-section and keel length enable it to land in the open sea. The Albatross was designed for optimal seas, and could land in more severe conditions, but required JATO (jet-assisted takeoff, or simply booster rockets) for takeoff in seas or greater. The Albatross initially carried an APS-31A radar in a pod on the left wing. However, the position meant the fuselage blocked the ability of the radar to searc ...

Helicopter
A helicopter is a type of rotorcraft in which Lift (force), lift and thrust are supplied by horizontally spinning Helicopter rotor, rotors. This allows the helicopter to VTOL, take off and land vertically, to hover (helicopter), 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 short take-off and landing (STOL) or short take-off and vertical landing (STOVL) aircraft cannot perform without a runway. The Focke-Wulf Fw 61 was the first successful, practical, and fully controllable helicopter in 1936, while in 1942, the Sikorsky R-4 became the first helicopter to reach full-scale mass production, production. Starting in 1939 and through 1943, Igor Sikorsky worked on the development of the Vought-Sikorsky VS-300, VS-300, which over four iterations, became the basis for modern helicopters with a single main rotor and a single tail rotor.

Vickers Viking Amphi
Vickers was a British engineering company that existed from 1828 until 1999. It was formed in Sheffield as a steel foundry by Edward Vickers and his father-in-law, and soon became famous for casting church bells. The company went public in 1867, acquired more businesses, and began branching out into military hardware and shipbuilding. In 1911, the company expanded into aircraft manufacture and opened a flying school. They expanded even further into electrical and railway manufacturing, and in 1928 acquired an interest in the Supermarine. Beginning in the 1960s, various parts of the company were nationalised, and in 1999 the rest of the company was acquired by Rolls-Royce plc, which sold the defence arm to Alvis plc. The Vickers name lived on in Alvis Vickers, until the latter was acquired by BAE Systems in 2004 to form BAE Systems Land Systems.
