Short Skyvan
The Short SC.7 Skyvan (nicknamed the "Flying Shoebox") is a British 19-seat twin-turboprop aircraft manufactured by Short Brothers of Belfast, Northern Ireland. It is used mainly for short-haul freight and skydiving. The Short 330 and Short 360 are stretched models of the original SC.7, designed as regional airliners. Design and development In 1958, Short was approached by F.G. Miles Ltd (successor company to Miles Aircraft) which was seeking backing to produce a development of the H.D.M.106 Caravan design with a high aspect ratio wing similar to that of the Hurel-Dubois HD.31. Short acquired the design and data gathered from trials of the Miles Aerovan based H.D.M.105 prototype. After evaluating the Miles proposal, Short rejected the Caravan. They developed their own design for a utility all-metal aircraft which was called the Short SC.7 Skyvan. The Skyvan is a twin-engined all-metal, high-wing monoplane, with a braced, high aspect ratio wing, and an unpressurised, squar ...

RAF Fairford
Royal Air Force Fairford or more simply RAF Fairford is a Royal Air Force (RAF) station in Gloucestershire, England which is currently a standby airfield and therefore not in everyday use. Its most prominent use in recent years has been as an airfield for United States Air Force B-52s during the 2003 Iraq War, Operation Allied Force in 1999, and the first Gulf War in 1991. It is the US Air Force's only European airfield for heavy bombers. RAF Fairford was the only TransOceanic Abort Landing site for NASA's Space Shuttle in the UK. As well as having a sufficiently long runway for a shuttle landing (the runway is long), it also had NASA-trained fire and medical crews stationed on the airfield. The runway is rated with an unrestricted load-bearing capacity, meaning that it can support any aircraft with any type of load. RAF Fairford is also the home of the Royal International Air Tattoo (RIAT), an annual air display. RIAT is one of the largest airshows in the world, with the 2 ...

Vertical Stabilizer
A vertical stabilizer or tail fin is the static part of the vertical tail of an aircraft. The term is commonly applied to the assembly of both this fixed surface and one or more movable rudders hinged to it. Their role is to provide control, stability and trim in yaw (also known as directional or weathercock stability). It is part of the aircraft empennage, specifically of its stabilizers. The vertical tail is typically mounted on top of the rear fuselage, with the horizontal stabilizers mounted on the side of the fuselage (a configuration termed "conventional tail"). Other configurations, such as T-tail or twin tail, are sometimes used instead. Vertical stabilizers have occasionally been used in motor sports, with for example in Le Mans Prototype racing. Function Principle The vertical tail of an aircraft typically consists of a fixed vertical stabilizer or fin on which a movable rudder is mounted. A trim tab may similarly be mounted on the rudder. Together, their role ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Argentine Naval Prefecture
The Argentine Naval Prefecture ( es, Prefectura Naval Argentina or PNA) is a service of Argentina's Security Ministry charged with protecting the country's rivers and maritime territory. It therefore fulfills the functions of other countries' coast guards, and furthermore acts as a gendarmerie force policing navigable rivers. According to the Argentine Constitution, the Armed Forces of the Argentine Republic cannot intervene in internal civil conflicts, so the Prefecture is defined as a civilian "security force of a military nature". It maintains a functional relationship with the Ministry of Defense, as part of both the National Defense System and the Interior Security System. It therefore maintains capabilities arising from the demands required by joint military planning with the armed forces. The PNA is a large organization for a coastguard. With a strength of 45,750 sworn members, the PNA is a larger organization than most national navies, and is in fact slightly larger tha ...

Río De La Plata
The Río de la Plata (, "river of silver"), also called the River Plate or La Plata River in English, is the estuary formed by the confluence of the Uruguay River and the Paraná River at Punta Gorda. It empties into the Atlantic Ocean and forms a funnel-shaped indentation on the southeastern coastline of South America. Depending on the geographer, the Río de la Plata may be considered a river, an estuary, a gulf, or a marginal sea. If considered a river, it is the widest in the world, with a maximum width of . The river is about long and widens from about at its source to about at its mouth. It forms part of the border between Argentina and Uruguay. The name Río de la Plata is also used to refer to the populations along the estuary, especially the main port cities of Buenos Aires and Montevideo, where Ríoplatense Spanish is spoken and tango culture developed. The coasts of the river are the most densely-populated areas of Uruguay and Argentina. Geography The Río d ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Forced Disappearance
An enforced disappearance (or forced disappearance) is the secret abduction or imprisonment of a person by a state or political organization, or by a third party with the authorization, support, or acquiescence of a state or political organization, followed by a refusal to acknowledge the person's fate and whereabouts, with the intent of placing the victim outside the protection of the law. According to the Rome Statute of the International Criminal Court, which came into force on 1 July 2002, when committed as part of a widespread or systematic attack directed at any civilian population, a "forced disappearance" qualifies as a crime against humanity, not subject to a statute of limitations, in international criminal law. On 20 December 2006, the United Nations General Assembly adopted the International Convention for the Protection of All Persons from Enforced Disappearance. Often, forced disappearance implies murder: a victim is abducted, may be illegally detained and of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dirty War
The Dirty War ( es, Guerra sucia) is the name used by the military junta or civic-military dictatorship of Argentina ( es, dictadura cívico-militar de Argentina, links=no) for the period of state terrorism in Argentina from 1974 to 1983 as a part of Operation Condor, during which military and security forces and right-wing death squads in the form of the Argentine Anticommunist Alliance (AAA, or Triple A) hunted down any political dissidents and anyone believed to be associated with socialism, left-wing Peronism, or the Montoneros movement.''Political Violence and Trauma in Argentina, '' Antonius C.

Death Flight
Death flights ( es, vuelos de la muerte, links=no) are a form of extrajudicial killing practiced by military forces in possession of aircraft: victims are dropped to their death from airplanes or helicopters into oceans, large rivers or even mountains. Death flights have been carried out in a number of internal conflicts, including by France during the 1947 Malagasy Uprising and the 1957 Battle of Algiers, and by the junta dictatorship during the Argentine Dirty War between 1976 and 1983. During the Bougainville conflict PNGDF helicopters were used to dispose of corpses that had died under torture, and in some cases, still living victims. Countries Argentina During the 1976–1983 Argentine Dirty War, many thousands of people disappeared, clandestinely kidnapped by groups acting for the dictatorship. Human rights groups in Argentina often cite a figure of 30,000 disappeared; Amnesty International estimates 20,000. Many were killed in death flights, a practice initiated by ...

Shorts SC
Shorts are a garment worn over the pelvic area, circling the waist and splitting to cover the upper part of the legs, sometimes extending down to the knees but not covering the entire length of the leg. They are called "shorts" because they are a shortened version of trousers, which cover the entire leg, but not the foot. Shorts are typically worn in warm weather or in an environment where comfort and airflow are more important than the protection of the legs. There are a variety of shorts, ranging from knee-length short trousers that can in some situations be worn as formal clothes to beachwear and athletic shorts. Some types of shorts are typically worn by women, such as culottes, which are a divided skirt resembling a pair of loose-cut shorts. Terminological differences The British English term, ''short trousers'', is used, only for shorts that are a short version of ordinary trousers (i.e., ''pants'' or ''slacks'' in American English). For example: tailored shorts, often ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Garrett TPE331
The Honeywell TPE331 (military designation: T76) is a turboprop engine. It was originally designed in the 1950s by Garrett AiResearch, and produced since 1999 by Honeywell Aerospace. The engine's power output ranges from . Design and development Garrett AiResearch designed the TPE331 from scratch in 1959 for the military. “Designed as a 575-horsepower engine it was not a scaled-down version of a larger engine, as competitors were offering.” The TPE331 originated in 1961 as a gas turbine (the "331") to power helicopters. It first went into production in 1963. More than 700 had been shipped by the end of 1973. It was designed to be both a turboshaft (TSE331) and a turboprop (TPE331), but the turboshaft version never went into production. The first engine was produced in 1963, installed on the Aero Commander in 1964 and put into production on the Aero Commander Turbo Commander in June 1965. Performance The 715 shp TPE331-6 used in the Beech King Air B100 have a 400-hr. fuel ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Turbomeca Astazou
The Turbomeca Astazou is a highly successful series of turboprop and turboshaft engines, first run in 1957. The original version weighed and developed at 40,000 rpm. It was admitted for aviation service on May 29, 1961, after a 150-hour test run. The main developing engineer was G. Sporer. It was named after two summits of the Pyrenees. A simplified version was built by Agusta as the Turbomeca-Agusta TA.230. Design and development The Astazou IIA version was derived from the original Astazou powerplant for use in helicopters. By 1993, 2,200 had been built. As of 2007, it was still in production. However, many aircraft initially equipped with it, especially the heavier ones, have since been upgraded with more powerful engines. The early single-shaft Astazou has a two-stage compressor, with the first stage an axial and the second stage a radial design. It has an annular combustion chamber, after which the combustion gases enter a three-stage axial turbine. Engines have a reduc ...

Turbomeca
Safran Helicopter Engines, previously known as Turbomeca, is a French manufacturer of low- and medium-power gas turbine turboshaft engines for helicopters. The company also produces gas turbine engines for aircraft and missiles, as well as turbines for land, industrial and marine applications. Since its founding as ''Turbomeca'' during 1938, Safran Helicopter Engines has produced over 72,000 turbines.
