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 (watercraft), hull like a flying boat or it can be fitted with utility Floats (nautical), 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, have the advantage of VTOL, and can deliver injured passengers directly to hospitals or other emergency facilities (requiring no runway or airport). A practical amphibious helicopter first appeared in 1941 and the water-landing feature soon proved its worth. Non-amphibious helicopt ...

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, and it is 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, but are considered accidents. Most times, ditching results in aircraft structural failure. 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 transportat ...

Rescue Swimmer
Rescue swimmer is a qualification 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 United States Coast Guard Aviation Survival Technician (AST)/Helicopter Rescue Swimmer team is trained to respond in extreme rescue situations, such as medical evacuations, downed aviators, sinking vessels, and hurricanes. 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 highest attrition rates of any military school with about 80% of candidates failing to complete the program. F ...

Helicopter Rescue Basket
A helicopter Litter (rescue basket), 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 b ... [...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 Westland Lysander, 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 V ...

Mitsubishi
The is a group of autonomous Japanese multinational companies in a variety of industries. Founded by Yatarō Iwasaki in 1870, the Mitsubishi Group traces its origins to the Mitsubishi zaibatsu, a unified company that existed from 1870 to 1946. The company, along with other major zaibatsu, was disbanded during the occupation of Japan following World War II by the order of the Allies. Despite the dissolution, the former constituent companies continue to share the Mitsubishi brand and trademark. While the group of companies engages in limited business cooperation, most notably through monthly "Friday Conference" executive meetings, they remain formally independent and are not under common control. The three main entities ('' gosanke'') are Mitsubishi UFJ Financial Group (the largest bank in Japan), Mitsubishi Corporation (a general trading company), and Mitsubishi Heavy Industries (a diversified manufacturing company). A 2020 estimate concluded that all the Mitsubishi compani ... [...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 aeroplane 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, Leonardo S.p.A. 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 e ...

Anti-submarine Warfare
Anti-submarine warfare (ASW, or in the older form A/S) is a branch of underwater warfare that uses surface warships, aircraft, submarines, or other platforms, to find, track, and deter, damage, or destroy enemy submarines. Such operations are typically carried out to protect friendly shipping and coastal facilities from submarine attacks and to overcome blockades. Successful ASW operations typically involve a combination of sensor and weapon technologies, along with effective deployment strategies and sufficiently trained personnel. Typically, sophisticated sonar equipment is used for first detecting, then classifying, locating, and tracking a target submarine. Sensors are therefore a key element of ASW. Common weapons for attacking submarines include torpedoes and naval mines, which can both be launched from an array of air, surface, and underwater platforms. ASW capabilities are often considered of significant strategic importance, particularly following provocative instanc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sikorsky S-55
The Sikorsky H-19 Chickasaw (company model number S-55) is a multi-purpose piston-engined helicopter that was used by the United States Army and United States Air Force. It was also license-built by Westland Aircraft as the Westland Whirlwind in the United Kingdom. United States Navy and United States Coast Guard models were designated HO4S, while those of the U.S. Marine Corps were designated HRS. In 1962, the U.S. Navy, U.S. Coast Guard and U.S. Marine Corps versions were all redesignated as H-19s like their U.S. Army and U.S. Air Force counterparts. The H-19 pioneered the use of a nose-mounted radial engine powering a single fully articulated main rotor located above the cabin, which helped maintain a proper center of gravity under varying loading conditions without requiring ballast to maintain longitudinal stability as with prior Sikorsky designs. This layout gave the H-19 series a characteristic bulbous-nosed appearance and made it one of the first truly successful si ...
