Bell OH-58 Kiowa
The Bell OH-58 Kiowa is a family of single-engine single- rotor military helicopters used for observation, utility, and direct fire support. It was produced by the American manufacturer Bell Helicopter and is closely related to the Model 206A JetRanger civilian helicopter. The OH-58 was originally developed during the early 1960s as the ''D-250'' for the Light Observation Helicopter (LOH). While the rival Hughes OH-6 Cayuse was picked over Bell's submission in May 1965, the company refined its design to create the Model 206A, a variant of which it successfully submitted to the reopened LOH competition two years later. The initial model, designated by the service as the ''OH-58A'', was introduced in May 1969. Successive models followed, often with uprated engines, enhanced protection systems, and other improvements, culminating in the ''OH-58F''. Additional improvements, such as the ''OH-58X'', were proposed but not pursued. During the 1970s, the US Army became interested i ...

United States Invasion Of Panama
The United States invaded Panama in mid-December 1989 during the presidency of George H. W. Bush. The purpose of the invasion was to depose the '' de facto'' ruler of Panama, General Manuel Noriega, who was wanted by U.S. authorities for racketeering and drug trafficking. The operation, codenamed Operation Just Cause, concluded in late January 1990 with the surrender of Noriega. The Panama Defense Forces (PDF) were dissolved, and President-elect Guillermo Endara was sworn into office. Noriega, who had longstanding ties to United States intelligence agencies, consolidated power to become Panama's ''de facto'' dictator in the early 1980s. In the mid-1980s, relations between Noriega and the U.S. began to deteriorate due to fallout of the murder of Hugo Spadafora and the removal from office of President Nicolas Ardito Barletta. His criminal activities and association with other spy agencies came to light, and in 1988 he was indicted by federal grand juries on several drug-rel ...

Fairchild Hiller FH-1100
The Fairchild Hiller FH-1100 is a single-engine turbine, single two-bladed rotor, light helicopter that was designed and produced by the American aircraft manufacturer Fairchild Aircraft, Fairchild Hiller in the 1960s. Originally designated as the ''Model 1100'', it was produced as the company's design submission for the United States Army's Light Observation Helicopter (LOH) program. It was one of the three winning designs in May 1961, after which the military designation ''Hiller YOH-5'' was assigned; the prototype performed its maiden flight on 21 January 1963. However, following extensive evaluations of the type, the Model 1100 did not receive a production contract after Hiller was underbid by the rival Hughes Helicopters, Hughes Tool Co. Aircraft Division's OH-6 Cayuse in 1965. Shortly following the purchase of Hiller Aircraft by Fairchild Aircraft, Fairchild Engine and Airplane Corporation during 1964, the company decided to focus its efforts on the Model 1100, which was ...

Bell 47J Ranger
The Bell 47J Ranger is an American single-engine single-rotor light helicopter manufactured by Bell Helicopter. It was an executive variant of the highly successful Bell 47 and was the first helicopter to carry a United States president. Design and development The 47J was a four-seat variant of the earlier three-seat Bell 47H. The 47H was a deluxe variant of the 47G with a fully clad fuselage and an enclosed cabin. The 47H proved to be too small, so Bell developed the 47J. The 47J was a single pilot aircraft with the pilot seat and controls centered in the front of the cabin, and positioned close to the 180° view unobstructed Lexan "bubble" windscreen. A single bench seat at the rear of the cabin spanned its entire width and allowed for a passenger capacity limited by weight to typically 3 or 4 adults. Operational history In March 1957 two Bell 47Js were bought by the United States Air Force as presidential transport and designated H-13J. On 13 July 1957 a H-13J was the first ...

Maiden Flight
The maiden flight, also known as first flight, of an aircraft is the first occasion on which it leaves the ground under its own power. The same term is also used for the first launch of rockets. In the early days of aviation it could be dangerous, because the exact handling characteristics of the aircraft were generally unknown. The maiden flight of a new type is almost invariably flown by a highly experienced test pilot. Maiden flights are usually accompanied by a chase plane, to verify items like altitude, airspeed, and general airworthiness. A maiden flight is only one stage in the development of an aircraft type. Unless the type is a pure research aircraft (such as the X-15), the aircraft must be tested extensively to ensure that it delivers the desired performance with an acceptable margin of safety. In the case of civilian aircraft, a new type must be certified by a governing agency (such as the Federal Aviation Administration in the United States) before it can enter ...

Bell YOH-4
The Bell YOH-4 (originally YHO-4) was a single-engine, single-rotor light helicopter, developed for the United States Army's Light Observation Helicopter program. While the YOH-4A was unsuccessful in the original LOH competition, Bell redesigned it as the sleek Bell 206, Bell 206A JetRanger for the commercial market, and enjoyed instant and lasting success. In 1967, the Army reopened the LOH competition, and the 206A-based OH-58 Kiowa was selected. Development On 14 October 1960, the United States Navy solicited responses from 25 aircraft manufacturers to a request for proposals (RFP) on behalf of the Army for the Light Observation Helicopter (LOH). Bell entered the competition along with 12 other manufacturers, including Hiller Aircraft and Hughes Helicopters, Hughes Tool Co., Aircraft Division. In January 1961, Bell submitted Design 250 (D-250), which would eventually be designated as the ''YHO-4''.Beechy, Robert"U.S Army Aircraft Acquisition Programs". ''Uncommon Aircraft 2006 ...

Hughes Helicopters
Hughes Helicopters was a major manufacturer of military and civilian helicopters from the 1950s to the 1980s. The company began in 1947, as a unit of Hughes Aircraft, then was part of the Hughes Tool Company after 1955. It became the Hughes Helicopter Division, Summa Corporation in 1972, and was reformed as Hughes Helicopters, Inc. in 1981. However, throughout its history, the company was informally known as "Hughes Helicopters". It was sold to McDonnell Douglas in 1984 and made a subsidiary under the name ''McDonnell Douglas Helicopter Systems'', which was later renamed MD Helicopters when McDonnell Douglas merged with Boeing. History In 1947, Howard Hughes redirected the Hughes Aircraft Company's efforts from airplanes to helicopters. The effort began in earnest in 1948, when helicopter manufacturer Kellett Autogiro Corporation sold their latest design to Hughes for production. The XH-17 "Sky Crane" first flew in October 1952, but was commercially unsuccessful. In 1955 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Licensed Production
Licensed production is the production under license of technology developed elsewhere. The licensee provides the licensor of a specific product with legal production rights, technical information, process technology, and any other proprietary components that cannot be sourced by the licensor. This is an especially prominent commercial practice in developing nations, which often approach licensed production as a starting point for indigenous industrial development. While licensed production in developing nations provides stimulus to the production and technical capabilities of local industry, in many cases it remains at least partly dependent on foreign support. History The four most common applications of licensed production have historically been automotive engines and parts, weaponry, aircraft, and pharmaceuticals. During World War I, it was more common for licensing agreements to take place between companies in the same country; for example, Opel was granted a license to ...
