Sikorsky Aircraft
Sikorsky Aircraft is an American aircraft manufacturer based in Stratford, Connecticut. It was established by aviation pioneer Igor Sikorsky in 1923 and was among the first companies to manufacture helicopters for civilian and military use. Previously owned by United Technologies Corporation, in November 2015 Sikorsky was sold to Lockheed Martin. History On 5 March 1923, the Sikorsky Aero Engineering Corporation was founded near Roosevelt Field, New York, by Igor Sikorsky, an immigrant to the United States who was born in Kyiv. In 1925, the company name was changed to Sikorsky Manufacturing Company. After the success of the Sikorsky S-38">S-38, the company was reorganized as the Sikorsky Aviation Corporation with capital of $5,000,000, allowing the purchase of land and the building of a modern aircraft factory in Stratford.

WikiProject Aircraft
A WikiProject, or Wikiproject, is a Wikimedia movement affinity group for contributors with shared goals. WikiProjects are prevalent within the largest wiki, Wikipedia, and exist to varying degrees within sister projects such as Wiktionary, Wikiquote, Wikidata, and Wikisource. They also exist in different languages, and translation of articles is a form of their collaboration. During the COVID-19 pandemic, CBS News noted the role of Wikipedia's WikiProject Medicine in maintaining the accuracy of articles related to the disease. Another WikiProject that has drawn attention is WikiProject Women Scientists, which was profiled by '' Smithsonian'' for its efforts to improve coverage of women scientists which the profile noted had "helped increase the number of female scientists on Wikipedia from around 1,600 to over 5,000". On Wikipedia Some Wikipedia WikiProjects are substantial enough to engage in cooperative activities with outside organizations relevant to the field at issue. Fo ...

Vietnam War
The Vietnam War (also known by #Names, other names) was a conflict in Vietnam, Laos, and Cambodia from 1 November 1955 to the fall of Saigon on 30 April 1975. It was the second of the Indochina Wars and was officially fought between North Vietnam and South Vietnam. The north was supported by the Soviet Union, China, and other communist states, while the south was United States in the Vietnam War, supported by the United States and other anti-communism, anti-communist Free World Military Forces, allies. The war is widely considered to be a Cold War-era proxy war. It lasted almost 20 years, with direct U.S. involvement ending in 1973. The conflict also spilled over into neighboring states, exacerbating the Laotian Civil War and the Cambodian Civil War, which ended with all three countries becoming communist states by 1975. After the French 1954 Geneva Conference, military withdrawal from Indochina in 1954 – following their defeat in the First Indochina War – the Viet Minh to ...

Minigun
The M134 Minigun is an American 7.62×51mm NATO six-barrel rotary machine gun with a high rate of fire (2,000 to 6,000 rounds per minute). It features a Gatling-style rotating barrel assembly with an external power source, normally an electric motor. The "Mini" in the name is in comparison to larger-caliber designs that use a rotary barrel design, such as General Electric's earlier 20 mm M61 Vulcan, and "gun" for the use of rifle ammunition as opposed to autocannon shells. "Minigun" refers to a specific model of weapon that General Electric originally produced, but the term "minigun" has popularly come to refer to any externally powered rotary gun of rifle caliber. The term is sometimes used loosely to refer to guns of similar rates of fire and configuration, regardless of power source and caliber. The Minigun is used by several branches of the U.S. military. Versions are designated ''M134'' and ''XM196'' by the United States Army, and ''GAU-2/A'' and ''GAU-17/A'' by the U.S. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
PAVE
PAVE is a United States Air Force program identifier relating to electronic systems. Prior to 1979, Pave was said to be a code word for the Air Force unit responsible for the project. ''Pave'' was used as an inconsequential prefix identifier for a wide range of different programs, though backronyms and alternative meanings have been used. For example, in the helicopters Pave Low and Pave Hawk it was said to mean ''Precision Avionics Vectoring Equipment'', but in Pave Paws it was said to mean ''Precision Acquisition Vehicle Entry''. PAVE systems * Pave Eagle – Modified Beechcraft Bonanza drone aircraft for low altitude sensor monitoring. * Pave Hawk – Sikorsky HH-60 Pave Hawk special operations and combat search and rescue helicopter. * Pave Nail - OV-10 Bronco with Pave Spot target laser designator pod. * Pave Knife – Ford Aerospace AN/AVQ-10 Pave Knife early laser targeting pod. * Pave Low – Sikorsky MH-53 Pave Low special ops and combat search and rescue helicopt ...

Apollo Command/Service Module
The Apollo command and service module (CSM) was one of two principal components of the United States Apollo spacecraft, used for the Apollo program, which landed astronauts on the Moon between 1969 and 1972. The CSM functioned as a mother ship, which carried a crew of three astronauts and the second Apollo spacecraft, the Apollo Lunar Module, to lunar orbit, and brought the astronauts back to Earth. It consisted of two parts: the conical command module, a cabin that housed the crew and carried equipment needed for atmospheric reentry and splashdown; and the cylindrical service module which provided propulsion, electrical power and storage for various consumables required during a mission. An umbilical connection transferred power and consumables between the two modules. Just before reentry of the command module on the return home, the umbilical connection was severed and the service module was cast off and allowed to burn up in the atmosphere. The CSM was developed and bu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
United States Air Force Pararescue
Pararescuemen (also known as PJs) are United States Air Force Special Operations Command (AFSOC) and Air Combat Command (ACC) operators tasked with recovery and medical treatment of personnel in humanitarian and combat environments. These special operations units are also used to support NASA missions and have been used to recover astronauts after water landings. They are attached to other special operations units from all branches to conduct other operations as appropriate. Of the roughly 200 Air Force Cross recipients, only 24 are enlisted rank, of which 12 are Pararescuemen. Part of the Air Force Special Operations community and long an enlisted preserve, the Pararescue service expanded to include Combat Rescue Officers early in the 21st century. History Pre–World War II As early as 1922, there was a recognized need for trained personnel to go to remote sites to rescue airmen. In that year, Army Medical Corps doctor Colonel Albert E. Truby predicted that "airpl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gatling
The Gatling gun is a rapid-firing multiple-barrel firearm invented in 1861 by Richard Jordan Gatling. It is an early machine gun and a forerunner of the modern electric motor-driven rotary cannon. The Gatling gun's operation centered on a cyclic multi-barrel design which facilitated cooling and synchronized the firing-reloading sequence. As the handwheel is cranked, the barrels rotate and each barrel sequentially loads a single cartridge from a top-mounted magazine, fires off the shot when it reaches a set position (usually at 4 o'clock), then ejects the spent casing out of the left side at the bottom, after which the barrel is empty and allowed to cool until rotated back to the top position and gravity-fed another new round. This configuration eliminated the need for a single reciprocating bolt design and allowed higher rates of fire to be achieved without the barrels overheating quickly. One of the best-known early rapid-fire firearms, the Gatling gun saw occasional ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
