Skunk Works
Skunk Works is an official pseudonym for Lockheed Martin's Advanced Development Programs (ADP), formerly called Lockheed Advanced Development Projects. It is responsible for a number of aircraft designs, beginning with the Lockheed P-38 Lightning, P-38 Lightning in 1939 and the Lockheed P-80 Shooting Star, P-80 Shooting Star in 1943. Skunk Works engineers subsequently developed the Lockheed U-2, U-2, Lockheed SR-71 Blackbird, SR-71 Blackbird, Lockheed F-117 Nighthawk, F-117 Nighthawk, Lockheed Martin F-22 Raptor, F-22 Raptor, and Lockheed Martin F-35 Lightning II, F-35 Lightning II, the latter being used in the air force, air forces of several countries. The Skunk Works name was taken from the "Skonk Oil" factory in the comic strip ''Li'l Abner''. The designation Skunkworks project, "skunk works" or "skunkworks" is widely used in business, engineering, and technical fields to describe a group within an organization given a high degree of autonomy and unhampered by bureaucracy, ...

Lockheed Corporation
The Lockheed Corporation was an American aerospace manufacturer. Lockheed was founded in 1926 and later merged with Martin Marietta to form Lockheed Martin in 1995. Its founder, Allan Lockheed, had earlier founded the similarly named but otherwise-unrelated Loughead Aircraft Manufacturing Company, which was operational from 1912 to 1920. History Origins Allan Loughead and his brother Malcolm Loughead had operated an earlier aircraft company, Loughead Aircraft Manufacturing Company, which was operational from 1912 to 1920. The company built and operated aircraft for paying passengers on sightseeing tours in California and had developed a prototype for the civil market, but folded in 1920 due to the flood of surplus aircraft deflating the market after World War I. Allan went into the real estate market while Malcolm had meanwhile formed a successful company marketing brake systems for automobiles. On December 13, 1926, Allan Lockheed, Jack Northrop, John Northrop, Kenneth K ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cherokee Phoenix
The ''Cherokee Phoenix'' ( chr, ᏣᎳᎩ ᏧᎴᎯᏌᏅᎯ, translit=Tsalagi Tsulehisanvhi) is the first newspaper published by Native Americans in the United States and the first published in a Native American language. The first issue was published in English and Cherokee on February 21, 1828, in New Echota, capital of the Cherokee Nation (present-day Georgia). The paper continued until 1834. The ''Cherokee Phoenix'' was revived in the 20th century, and today it publishes both print and Internet versions. 19th century In the mid-1820s the Cherokee tribe was being pressured by the government, and by Georgia in particular, to remove to new lands west of the Mississippi River, or to end their tribal government and surrender control of their traditional territory to the United States (US) government. The General Council of the Cherokee Nation established a newspaper, in collaboration with Samuel Worcester, a missionary, who cast the type for the Cherokee syllabary. The Council ...

Native Americans In The United States
Native Americans, also known as American Indians, First Americans, Indigenous Americans, and other terms, are the Indigenous peoples of the mainland United States ( Indigenous peoples of Hawaii, Alaska and territories of the United States are generally known by other terms). There are 574 federally recognized tribes living within the US, about half of which are associated with Indian reservations. As defined by the United States Census, "Native Americans" are Indigenous tribes that are originally from the contiguous United States, along with Alaska Natives. Indigenous peoples of the United States who are not listed as American Indian or Alaska Native include Native Hawaiians, Samoan Americans, and the Chamorro people. The US Census groups these peoples as " Native Hawaiian and other Pacific Islanders". European colonization of the Americas, which began in 1492, resulted in a precipitous decline in Native American population because of new diseases, wars, ethni ...

P-80 Shooting Star
The Lockheed P-80 Shooting Star was the first jet fighter used operationally by the United States Army Air Forces The United States Army Air Forces (USAAF or AAF) was the major land-based aerial warfare service component of the United States Army and ''de facto'' aerial warfare service branch of the United States during and immediately after World War II ... (USAAF) during World War II. Designed and built by Lockheed Corporation, Lockheed in 1943 and delivered just 143 days from the start of design, production models were flying, and two pre-production models did see very limited service in Italy just before the end of World War II. Designed with straight wings, the type saw extensive combat in Korea with the United States Air Force (USAF) as the F-80. America's first successful turbojet-powered combat aircraft, it was soon outclassed with the appearance of the swept-wing transonic MiG-15 and was quickly replaced in the air superiority role by the transonic F-86 Sabre. ...

Drop Tank
In aviation, a drop tank (external tank, wing tank or belly tank) is used to describe auxiliary fuel tanks externally carried by aircraft. A drop tank is expendable and often capable of being jettisoned. External tanks are commonplace on modern military aircraft and occasionally found in civilian ones, although the latter are less likely to be discarded except in an emergency. Overview The primary disadvantage with drop tanks is that they impose a drag penalty on the aircraft. External fuel tanks will also increase the moment of inertia, thereby reducing roll rates for air maneuvers. Some of the drop tank's fuel is used to overcome the added drag and weight of the tank. Drag in this sense varies with the square of the aircraft's speed. The use of drop tanks also reduces the number of external hardpoints available for weapons, reduces the weapon-carrying capacity and increases the aircraft's radar signature. Usually the fuel in the drop tanks is consumed first, and only when a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Joggle Bending
Bending is a manufacturing process that produces a V-shape, U-shape, or channel shape along a straight axis in ductile materials, most commonly sheet metal.Manufacturing Processes Reference Guide, Industrial Press Inc., 1994. Commonly used equipment include box and pan brakes, brake presses, and other specialized machine presses. Typical products that are made like this are boxes such as electrical enclosures and rectangular ductwork. Process In press brake forming, a work piece is positioned over the die block and the die block presses the sheet to form a shape. Usually bending has to overcome both tensile stresses and compressive stresses. When bending is done, the residual stresses cause the material to ' towards its original position, so the sheet must be over-bent to achieve the proper bend angle. The amount of spring back is dependent on the material, and the type of forming. When sheet metal is bent, it stretches in length. The ''bend deduction'' is the amount the ...

P-38 Lightning
The Lockheed P-38 Lightning is an American single-seat, twin piston-engined fighter aircraft that was used during World War II. Developed for the United States Army Air Corps by the Lockheed Corporation, the P-38 incorporated a distinctive twin-boom design with a central nacelle containing the cockpit and armament. Along with its use as a general fighter, the P-38 was used in various aerial combat roles, including as a highly effective fighter-bomber, a night fighter, and a long-range escort fighter when equipped with drop tanks. The P-38 was also used as a bomber-pathfinder, guiding streams of medium and heavy bombers, or even other P-38s equipped with bombs, to their targets."P-38 Lightning" National Museum of the United States Air Force.

Lockheed Hudson
The Lockheed Hudson is a light bomber and coastal reconnaissance aircraft built by the American Lockheed Aircraft Corporation. It was initially put into service by the Royal Air Force shortly before the outbreak of the Second World War and primarily operated by it thereafter. The Hudson was a military conversion of the Model 14 Super Electra airliner, and was the first significant aircraft construction contract for Lockheed — the initial RAF order for 200 Hudsons far surpassed any previous order the company had received. The Hudson served throughout the war, mainly with Coastal Command but also in transport and training roles, as well as delivering agents into occupied France. It was also used extensively with the Royal Canadian Air Force's anti-submarine squadrons and by the Royal Australian Air Force. Design and development In late 1937 Lockheed sent a cutaway drawing of the Model 14 to various publications, showing the new aircraft as a civilian aircraft and converte ...

Fighter Aircraft
Fighter aircraft are fixed-wing military aircraft designed primarily for air-to-air combat. In military conflict, the role of fighter aircraft is to establish air superiority of the battlespace. Domination of the airspace above a battlefield permits bombers and attack aircraft to engage in tactical and strategic bombing of enemy targets. The key performance features of a fighter include not only its firepower but also its high speed and maneuverability relative to the target aircraft. The success or failure of a combatant's efforts to gain air superiority hinges on several factors including the skill of its pilots, the tactical soundness of its doctrine for deploying its fighters, and the numbers and performance of those fighters. Many modern fighter aircraft also have secondary capabilities such as ground attack and some types, such as fighter-bombers, are designed from the outset for dual roles. Other fighter designs are highly specialized while still filling the ma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
