Amphibious Helicopter
An amphibious helicopter is a helicopter that is intended to land on and take off from both land and water. Amphibious helicopters are used for a variety of specialized purposes including air-sea rescue, marine salvage and oceanography, in addition to other tasks that can be accomplished with any non-amphibious helicopter. An amphibious helicopter can be designed with a waterproof or water-resistant hull like a flying boat or it can be fitted with utility floats in the same manner as a floatplane. Development Helicopters have taken a primary role in air-sea rescue since their introduction in the 1940s. Helicopters can fly in rougher weather than fixed-wing aircraft, and they can deliver injured passengers directly to hospitals or other emergency facilities. A practical amphibious helicopter first appeared in 1941 and the water-landing feature soon proved its worth. Non-amphibious helicopters were required to hover above the scene of a water accident and utilize a hoist but amphi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
HH3 2 300
The Sikorsky S-61R is a twin-engine helicopter used in transport or search and rescue roles. A developed version of the S-61/SH-3 Sea King, the S-61R was also built under license by Agusta as the AS-61R. The S-61R served in the United States Air Force as the CH-3C/E Sea King and the HH-3E Jolly Green Giant, and with the United States Coast Guard as the HH-3F "Pelican".United States Department of Defense. ''DOD 4120.15-L Model Designation of Military Aircraft, Rockets, and Guided Missiles''. Washington, DC: Department of Defense, 1974. p. A-40; 1998. p. A-43; 2004. p. 43. Development The Sikorsky S-61R was developed as a derivative of their S-61/SH-3 Sea King model. It features a substantially revised fuselage with a rear loading ramp, a conventional, though watertight, hull instead of the S-61's boat-hull, and retractable tricycle landing gear. The fuselage layout was used by Sikorsky for the larger CH-53 variants, and by the much later (though similarly sized) S-92. In ...

CH-124 Sea King
The Sikorsky CH-124 Sea King is a twin-engined anti-submarine warfare (ASW) helicopter designed for shipboard use by Canadian naval forces, based on the US Navy's Sikorsky SH-3 Sea King, SH-3. It served with the Royal Canadian Navy (RCN) and Canadian Armed Forces from 1963 to 2018. Design and development The advent of nuclear-powered submarines in the late 1950s let to the RCN assessing this new threat. While noisier than older submarines and thus detectable at longer ranges, nuclear submarines could also reach while submerged, faster than the RCN's new destroyer escort's top speed of . There were doubts that destroyers could effectively pursue and destroy such fast vessels, even when operating in pairs. During a 25 February 1959 Naval Board meeting, it was decided to counter the threat by operating helicopters from destroyers.Soward 1995, pp.169–171. The RCN examined the feasibility of operating ASW helicopters from small escorts, adding a temporary helicopter landing pla ...

Outrigger
An outrigger is a projecting structure on a boat, with specific meaning depending on types of vessel. Outriggers may also refer to legs on a wheeled vehicle that are folded out when it needs stabilization, for example on a crane that lifts heavy loads. Powered vessels and sailboats An outrigger describes any contraposing float rigging beyond the side (gunwale) of a boat to improve the vessel's stability. If a single outrigger is used it is usually but not always windward. The technology was originally developed by the Austronesian people. There are two main types of boats with outriggers: double outriggers (prevalent in maritime Southeast Asia) and single outriggers (prevalent in Madagascar, Melanesia, Micronesia and Polynesia). Multihull ships are also derived from outrigger boats. In an outrigger canoe and in sailboats such as the proa, an outrigger is a thin, long, solid, hull used to stabilise an inherently unstable main hull. The outrigger is positioned rigidly and ...

Piasecki H-25
The Piasecki HUP Retriever/H-25 Army Mule is a compact single radial engine, twin overlapping tandem rotor utility helicopter developed by the Piasecki Helicopter Corporation of Morton, Pennsylvania. Designed to a United States Navy specification, the helicopter was produced from 1949 to 1954, and was also used by the United States Army and foreign navies. The HUP/H-25 was the first helicopter to be produced with an autopilot and also the first to perform a loop. Design and development The design was a product of a competition by the U.S. Navy in 1945 for a compact utility/rescue helicopter to operate from ships including aircraft carriers, battleships, and cruisers. Either 2 or 3 prototypes—designated PV-14 by the factory and XHJP-1 by the Navy—were built and subjected to a side-by-side flight evaluation against the 3 prototypes of the Sikorsky XHJS-1; however, the XHJS was fundamentally a scaled-up version of the Sikorsky H-5, and the increased weight and size magnified the ...

Water Landing
In aviation, a water landing is, in the broadest sense, an aircraft landing on a body of water. Seaplanes, such as floatplanes and flying boats, land on water as a normal operation. Ditching is a controlled emergency landing on the water surface in an aircraft not designed for the purpose, a very rare occurrence. Controlled flight into the surface and uncontrolled flight ending in a body of water (including a runway excursion into water) are generally not considered water landings or ditching. Aircraft water landings By design Seaplanes, flying boats, and amphibious aircraft are designed to take off and alight on water. Alighting can be supported by a hull-shaped fuselage and/or pontoons. The availability of a long effective runway was historically important on lifting size restrictions on aircraft, and their freedom from constructed strips remains useful for transportation to lakes and other remote areas. The ability to loiter on water is also important for marine ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Rescue Swimmer
Rescue swimmer is a designation given to rescue specialists, most commonly in the service of the military. Rescue swimmers usually are charged with the rescue, assessment, and rendering of medical aid to persons in distress in the sea, on the land, or in the air. This highly specialized position is extremely challenging. United States U.S. Coast Guard Arguably the most widely recognized team of rescue-swimmer operators, the elite United States Coast Guard Aviation Survival Technician (AST)/Helicopter Rescue Swimmer team is called upon to respond in the most extreme rescue situations. High seas, medical evacuations, downed aviators, sinking vessels, and hurricanes are some of the deadly scenarios that Coast Guard rescue swimmers are trained to handle. The Coast Guard's team of ASTs is composed of about 350 active-duty members, and just over 1000 members have passed the training to become Helicopter Rescue Swimmers since the mid-1980s. The training school has one of the highe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Helicopter Rescue Basket
A helicopter rescue basket is a basket suspended below a helicopter in order to rescue people from a fire or other disaster site. Uses There are two main types of helicopter baskets. The smaller, more common type is used by rescuers to lift a person up from ground or water into the helicopter. An early type that could scoop an unconscious person from the sea was the Sproule Net, invented by Lt Cdr John Sproule, RN, in 1956 which was used by British helicopter rescue units until the late 1970s. The second type is a new invention. This is a basket able to fit five people or more. It allows a large group of people to be rescued from a fire or other emergency site, without needing to load them into the helicopter itself. It enables the helicopter to load a large group without landing. The helicopter hovers over the site and rests the basket on the ground or other surface. Evacuees board, then are transported to a safe area. This type of basket was tested by the Air National Guard ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Westland Aircraft
Westland Aircraft was a British aircraft manufacturer located in Yeovil, Somerset. Formed as a separate company by separation from Petters Limited just before the start of the Second World War, Westland had been building aircraft since 1915. During the war the company produced a number of generally unsuccessful designs, but their Lysander would serve as an important liaison aircraft with the Royal Air Force. After the war the company focused on helicopters, and was merged with several other British firms to create Westland Helicopters in 1961. History Foundation In 1915 the Westland Aircraft Works was founded as a division of Petters in response to government orders for the construction under licence of initially 12 Short Type 184 seaplanes, followed by 20 Short Admiralty Type 166. Orders for other aircraft followed during First World War, including the Sopwith 1½ Strutter, the de Havilland designed Airco DH.4, Airco DH.9 and Airco DH.9A and the Vickers Vimy. The name ...

Mitsubishi
The is a group of autonomous Japanese multinational companies in a variety of industries. Founded by Yatarō Iwasaki in 1870, the Mitsubishi Group historically descended from the Mitsubishi zaibatsu, a unified company which existed from 1870 to 1946. The company was disbanded during the occupation of Japan following World War II. The former constituents of the company continue to share the Mitsubishi brand and trademark. Although the group of companies participate in limited business cooperation, most famously through monthly "Friday Conference" executive meetings, they are formally independent and are not under common control. The four main companies in the group are MUFG Bank (the largest bank in Japan), Mitsubishi Corporation (a general trading company), Mitsubishi Electric and Mitsubishi Heavy Industries (both diversified manufacturing companies). History The Mitsubishi company was established as a shipping firm by Iwasaki Yatarō (1834–1885) in 1870 under the name ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Agusta
Agusta was an Italian helicopter manufacturer. It was based in Samarate, Northern Italy. The company was founded by Count Giovanni Agusta in 1923, who flew his first airplane in 1907. The MV Agusta motorcycle manufacturer began as an offshoot of the Agusta aviation company at the end of the Second World War, as a means to save the jobs of employees of the Agusta firm. In July 2000, Agusta merged with Westland Helicopters to form AgustaWestland S.p.A., a Multinational corporation, multinational helicopter design and manufacturing company, and a wholly owned subsidiary of Finmeccanica. History From 1952, the company became involved in helicopter manufacturing, first building Bell Aircraft Corporation, Bell helicopters under licence, but later Sikorsky Aircraft, Sikorsky, Boeing and McDonnell Douglas products as well. The company also had ambitions to design and build its own helicopters. The Agusta A.101 and the Agusta A.106 can be considered the best of its earlier attempts. O ...
