Boeing–Sikorsky RAH-66 Comanche
The Boeing–Sikorsky RAH-66 Comanche is an American stealth armed reconnaissance and attack helicopter designed for the United States Army. Following decades of development, the RAH-66 program was canceled in 2004 before mass production began, by which point nearly US$7 billion had been spent on the program. During the early 1980s, the U.S. Army started to formulate requirements for the replacement of its helicopters then in service, which resulted in the launch of the Light Helicopter Experimental (LHX) program. Nearly a decade later, following the refinement of requirements, evaluation of submissions, and the rebranding of the program as the ''Light Helicopter'' (LH) program, during April 1991, the Army announced the selection of the Boeing– Sikorsky team's design as the contest winner, shortly after which a contract for construction of prototypes was awarded. The Comanche was to incorporate several advanced elements, such as stealth technologies, and a number of previous ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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. For e ...

OH-6 Cayuse
The Hughes OH-6 Cayuse is a single-engine light helicopter that was designed and produced by the American aerospace company Hughes Helicopters. Its formal name is derived from the Cayuse people while its "Loach" nickname comes from the acronym for the Light Observation Helicopter (LOH) programme that it was procured under. The OH-6 was developed in response to the United States Army issuing Technical Specification 153 in 1960 to replace its Bell H-13 Sioux fleet. The ''Model 369'' was submitted by Hughes, and competed against the two finalists, Fairchild-Hiller and Bell, for a production contract. On 27 February 1963, the first prototype conducted its maiden flight. The Model 369 had a distinctive teardrop-shaped fuselage that had strong crashworthiness properties and provided excellent external visibility. Its four-bladed full-articulated main rotor made it particularly agile, and it was suitable for personnel transport, escort and attack missions, and observation. During May ...

Manufacturer's Weight Empty
In aviation, manufacturer's empty weight (MEW) (also known as manufacturer's weight empty (MWE)) is the weight of the aircraft "as built" and includes the weight of the structure, power plant, furnishings, installations, systems, and other equipment that are considered an integral part of an aircraft before additional operator items are added for operation. ''Basic aircraft empty weight'' is essentially the same and excludes any baggage, passengers, or usable fuel. Some manufacturers define this empty weight as including optional equipment, i.e. GPS units, cargo baskets, or spotlights. Specification MEW This is the MEW quoted in the manufacturer's standard specification documents and is the aircraft standard basic dry weight upon which all other standard specifications and aircraft performance are based by the manufacturer. The Specification MEW includes the weight of:Torenbeek, Egbert. ''Synthesis of Subsonic Airplane Design''. Delft University Press. . * Airframe structure â ...

United States Military Aircraft Serials
In the United States, all military aircraft display a serial number to identify individual aircraft. These numbers are located on the aircraft tail, so they are sometimes referred to unofficially as "tail numbers". On the Northrop Grumman B-2 Spirit bomber, lacking a tail, the number appears on the nose gear door. Individual agencies have each evolved their own system of serial number identification. Aircraft serials are part of the Aircraft Visual Identification System, which also includes the aircraft's tail code and Modex. History United States Army Signal Corps In 1908, the United States government purchased its first heavier than air aircraft. The aircraft, a Wright Model A, was used by the aviation section of the United States Army Signal Corps and was issued with serial number 1. Subsequent aircraft were numbered in sequence. United States Army Air Service In 1918, the aviation section of the Army Air Service became the United States Army Air Service (USAAS), but the s ...

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. The maiden flight of a new aircraft type is always a historic occasion for the type and can be quite emotional for those involved. 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 typ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
