Lockheed Jetstar
The Lockheed JetStar (company designations L-329 and L-1329; designated C-140 in US military service) is a business jet produced from the early 1960s to the 1970s. The JetStar was the first dedicated business jet to enter service, as well as the only such airplane built by Lockheed. It was also one of the largest aircraft in the class for many years, seating ten plus two crew. It is distinguishable from other small jets by its four engines, mounted on the rear of the fuselage, and the "slipper"-style fuel tanks fixed to the wings. Development The JetStar originated as a private project within Lockheed, with an eye to winning a United States Air Force (USAF) requirement that was later dropped due to budget cuts. Lockheed decided to continue the project on its own for the business market. The first two prototypes were equipped with two Bristol Siddeley Orpheus engines, the first of these flying on 4 September 1957. The second of these was also equipped with the wing-mounted " ...

Swept Wing
A swept wing is a wing that angles either backward or occasionally forward from its root rather than in a straight sideways direction. Swept wings have been flown since the pioneer days of aviation. Wing sweep at high speeds was first investigated in Germany as early as 1935 by Albert Betz and Adolph Busemann, finding application just before the end of the Second World War. It has the effect of delaying the shock waves and accompanying aerodynamic drag rise caused by fluid compressibility near the speed of sound, improving performance. Swept wings are therefore almost always used on jet aircraft designed to fly at these speeds. The term "swept wing" is normally used to mean "swept back", but variants include forward sweep, variable sweep wings and oblique wings in which one side sweeps forward and the other back. The delta wing is also aerodynamically a form of swept wing. Reasons for sweep There are three main reasons for sweeping a wing: 1. to arrange the center of ...

Very Important Person
A very important person or personage (VIP or V.I.P.) is a person who is accorded special privileges due to their high social status, influence or importance. The term was not common until sometime after World War 2 by RAF pilots. Examples include celebrities, heads of state or heads of government, other politicians, major employers, high rollers, high-level corporate officers, bankers, economists, physicians, clergy, military personnel, Crime bosses, wealthy individuals, or any other socially notable person who receives special treatment for any reason. The special treatment usually involves separation from common people, and a higher level of comfort or service. In some cases, such as with tickets, VIP may be used as a title in a similar way to ''premium'' or ''exclusive.'' Usually, VIP tickets can be purchased by anyone, but still meaning separation from other customers, own security checks etc. Sometimes, the term ''very very important person'' (''VVIP'' or ''V.V.I ...

Richard Nixon
Richard Milhous Nixon (January 9, 1913April 22, 1994) was the 37th president of the United States, serving from 1969 to 1974. A member of the Republican Party, he previously served as a representative and senator from California and was the 36th vice president from 1953 to 1961 under President Dwight D. Eisenhower. His five years in the White House saw reduction of U.S. involvement in the Vietnam War, détente with the Soviet Union and China, the first manned Moon landings, and the establishment of the Environmental Protection Agency and Occupational Safety and Health Administration. Nixon's second term ended early, when he became the only president to resign from office, as a result of the Watergate scandal. Nixon was born into a poor family of Quakers in a small town in Southern California. He graduated from Duke Law School in 1937, practiced law in California, then moved with his wife Pat to Washington in 1942 to work for the federal government. After activ ...

Elvis Presley
Elvis Aaron Presley (January 8, 1935 – August 16, 1977), or simply Elvis, was an American singer and actor. Dubbed the " King of Rock and Roll", he is regarded as one of the most significant cultural figures of the 20th century. His energized interpretations of songs and sexually provocative performance style, combined with a singularly potent mix of influences across color lines during a transformative era in race relations, led him to both great success and initial controversy. Presley was born in Tupelo, Mississippi, and relocated to Memphis, Tennessee, with his family when he was 13 years old. His music career began there in 1954, recording at Sun Records with producer Sam Phillips, who wanted to bring the sound of African-American music to a wider audience. Presley, on rhythm acoustic guitar, and accompanied by lead guitarist Scotty Moore and bassist Bill Black, was a pioneer of rockabilly, an uptempo, backbeat-driven fusion of country music and rhythm and ...

In 2003, as part of its commemoration of the 100th anniversary of t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Stabilizer (aeronautics)
An aircraft stabilizer is an aerodynamic surface, typically including one or more movable control surfaces, that provides longitudinal (pitch) and/or directional (yaw) stability and control. A stabilizer can feature a fixed or adjustable structure on which any movable control surfaces are hinged, or it can itself be a fully movable surface such as a stabilator. Depending on the context, "stabilizer" may sometimes describe only the front part of the overall surface. In the conventional aircraft configuration, separate vertical (fin) and horizontal (tailplane) stabilizers form an empennage positioned at the tail of the aircraft. Other arrangements of the empennage, such as the V-tail configuration, feature stabilizers which contribute to a combination of longitudinal and directional stabilization and control. Longitudinal stability and control may be obtained with other wing configurations, including canard, tandem wing and tailless aircraft. Some types of aircraft are stabili ...

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 rol ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Horizontal Stabilizer
A tailplane, also known as a horizontal stabiliser, is a small lifting surface located on the tail (empennage) behind the main lifting surfaces of a fixed-wing aircraft as well as other non-fixed-wing aircraft such as helicopters and gyroplanes. Not all fixed-wing aircraft have tailplanes. Canards, tailless and flying wing aircraft have no separate tailplane, while in V-tail aircraft the vertical stabiliser, rudder, and the tail-plane and elevator are combined to form two diagonal surfaces in a V layout. The function of the tailplane is to provide stability and control. In particular, the tailplane helps adjust for changes in position of the centre of pressure or centre of gravity caused by changes in speed and attitude, fuel consumption, or dropping cargo or payload. Tailplane types The tailplane comprises the tail-mounted fixed horizontal stabiliser and movable elevator. Besides its planform, it is characterised by: *Number of tailplanes - from 0 ( tailless or canard) ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
