Cessna 170
The Cessna 170 is an American light, single-engined, general aviation aircraft produced by the Cessna Aircraft Company between 1948 and 1956. It is the predecessor of the Cessna 172, the most produced aircraft in history, which replaced the 170 in production in 1956. Development 170 In late 1948, Cessna began sales of the 170, with a metal fuselage and tail and fabric-covered constant-chord wings. These earliest 170s were four-seat versions of the popular 140 with a more powerful Continental C145-2 and larger fuel tanks. Like the 140, they were constructed of metal with fabric-covered wings supported by a "V" strut. 170A In 1949 Cessna began marketing the 170A, an all-metal 170 with zero- dihedral wing tapered outboard of the slightly-enlarged plain flaps, and a single strut replacing the "V" strut of the 170. This and subsequent versions of the 170 shared the fin/rudder shape of the larger Cessna 190 and 195 models. 305 In 1950, the United States Air Force, Army ...

Air Force Of El Salvador
The Salvadoran Air Force ( es, Fuerza Aérea Salvadoreña, abbreviated FAS) is the air force component of the Armed Forces of El Salvador, and is an independent branch from the army and navy. Early history The Salvadoran Army Air Force ('' es, Fuerza Aérea de El Salvador'', abbreviated FAS) was formed on 20 March 1923 during a period of heavy interest in aviation in El Salvador. In 1947, after signing the treaty of Rio (which was a mutual defense treaty among the states of America including the U.S.), El Salvador gained a new US air mission and the United States increased transfers of aircraft to the nation. Recent operations The Salvadoran Air Force first saw action in the 1969 Football War against Honduras equipped with F4U Corsairs and P-51 Mustangs. From the late 1970s, isolated guerilla actions rapidly developed into a civil war. US aid to El Salvador in 1980 consisted of six UH-1Hs and four in 1981; they were used as gunships. Other deliveries brought that number of UH ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Lockheed F-104 Starfighter
The Lockheed F-104 Starfighter is an American single-engine, supersonic air superiority fighter which was extensively deployed as a fighter-bomber during the Cold War. Created as a day fighter by Lockheed as one of the "Century Series" of fighter aircraft for the United States Air Force (USAF), it was developed into an all-weather multirole aircraft in the early 1960s and produced by several other nations, seeing widespread service outside the United States. After a series of interviews with Korean War fighter pilots in 1951, Kelly Johnson, then lead designer at Lockheed, opted to reverse the trend of ever-larger and more complex fighters and produce a simple, lightweight aircraft with maximum altitude and climb performance. On 4 March 1954, the Lockheed XF-104 took to the skies for the first time, and on 26 February 1958 the production fighter was activated by the USAF. Only a few months later it was pressed into action during the Second Taiwan Strait Crisis, when it was d ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Boundary Layer Control
Boundary layer control refers to methods of controlling the behaviour of fluid flow boundary layers. It may be desirable to reduce flow separation on fast vehicles to reduce the size of the wake (streamlining), which may reduce drag. Boundary layer separation is generally undesirable in aircraft high lift coefficient systems and jet engine intakes. Laminar flow produces less skin friction than turbulent but a turbulent boundary layer transfers heat better. Turbulent boundary layers are more resistant to separation. The energy in a boundary layer may need to be increased to keep it attached to its surface. Fresh air can be introduced through slots or mixed in from above. The low momentum layer at the surface can be sucked away through a perforated surface or bled away when it is in a high pressure duct. It can be scooped off completely by a diverter or internal bleed ducting. Its energy can be increased above that of the free stream by introducing high velocity air. Nature Fran ...

Tricycle Landing Gear
Tricycle gear is a type of aircraft undercarriage, or ''landing gear'', arranged in a tricycle fashion. The tricycle arrangement has a single nose wheel in the front, and two or more main wheels slightly aft of the center of gravity. Tricycle gear aircraft are the easiest for takeoff, landing and taxiing, and consequently the configuration is the most widely used on aircraft.Crane, Dale: ''Dictionary of Aeronautical Terms, third edition'', page 524. Aviation Supplies & Academics, 1997. Aviation Publishers Co. Limited, ''From the Ground Up'', page 11 (27th revised edition) History Several early aircraft had primitive tricycle gear, notably very early Antoinette planes and the Curtiss Pushers of the pre-World War I Pioneer Era of aviation. Waldo Waterman's 1929 tailless '' Whatsit'' was one of the first to have a steerable nose wheel. In 1956, Cessna introduced sprung-steel tricycle landing gear on the Cessna 172. Their marketing department described this as "Land-O-Matic" ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Conventional Landing Gear
Conventional landing gear, or tailwheel-type landing gear, is an aircraft undercarriage consisting of two main wheels forward of the center of gravity and a small wheel or skid to support the tail.Crane, Dale: ''Dictionary of Aeronautical Terms, third edition'', page 133. Aviation Supplies & Academics, 1997. From the Ground Up, 27th edition, page 11 The term taildragger is also used, although some argue it should apply only to those aircraft with a tailskid rather than a wheel. The term "conventional" persists for historical reasons, but all modern jet aircraft and most modern propeller aircraft use tricycle gear. History In early aircraft, a tailskid made of metal or wood was used to support the tail on the ground. In most modern aircraft with conventional landing gear, a small articulated wheel assembly is attached to the rearmost part of the airframe in place of the skid. This wheel may be steered by the pilot through a connection to the rudder pedals, allowing the rudd ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Goodyear Tire And Rubber Company
The Goodyear Tire & Rubber Company is an American multinational tire manufacturing company founded in 1898 by Frank Seiberling and based in Akron, Ohio. Goodyear manufactures tires for automobiles, commercial trucks, light trucks, motorcycles, SUVs, race cars, airplanes, farm equipment and heavy earth-moving machinery. It also makes bicycle tires, having returned from a break in production between 1976 and 2015. As of 2017, Goodyear is one of the top five tire manufacturers along with Bridgestone (Japan), Michelin (France), Continental AG, Continental (Germany) and MRF (company), MRF (India). The company was named after American Charles Goodyear (1800–1860), inventor of Vulcanization, vulcanized rubber. The first Goodyear tires became popular because they were easily detachable and required little maintenance. Though Goodyear had been manufacturing airships and balloons since the early 1900s, the first Goodyear Blimp, Goodyear advertising blimp flew in 1925. Today, it is one o ...

Reconnaissance
In military operations, reconnaissance or scouting is the exploration of an area by military forces to obtain information about enemy forces, terrain, and other activities. Examples of reconnaissance include patrolling by troops (skirmishers, long-range reconnaissance patrol, U.S. Army Rangers, cavalry scouts, or military intelligence specialists), ships or submarines, crewed or uncrewed reconnaissance aircraft, satellites, or by setting up observation posts. Espionage is usually considered to be different from reconnaissance, as it is performed by non-uniformed personnel operating behind enemy lines. Often called recce (British, Canadian and Australian English) or recon (American English), the word for this activity has at its root the associated verb ''reconnoitre'' or ''reconnoiter''. Etymology The word from the Middle French ''reconoissance''. Overview Reconnaissance conducted by ground forces includes special reconnaissance, armored reconnaissance, amp ...

Forward Air Control
Forward air control is the provision of guidance to close air support (CAS) aircraft intended to ensure that their attack hits the intended target and does not injure friendly troops. This task is carried out by a forward air controller (FAC). A primary forward air control function is ensuring the safety of friendly troops during close air support. Enemy targets in the front line ("Forward Edge of the Battle Area" in US terminology) are often close to friendly forces and therefore friendly forces are at risk of friendly fire through proximity during air attack. The danger is twofold: the bombing pilot cannot identify the target clearly, and is not aware of the locations of friendly forces. Camouflage, a constantly changing situation and the fog of war all increase the risk. Present day doctrine holds that Forward Air Controllers (FACs) are not needed for air interdiction, although there has been such use of FACs in the past. An additional concern of forward air controllers is ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
