Citation I
The Cessna 500 Citation I is a small business jet produced by Cessna, the basis of the Citation family. The Fanjet 500 prototype was announced in October 1968, first flew on September 15, 1969, and was certified as the 500 Citation on September 9, 1971. It was upgraded in 1976 as the ''Citation I'', and the 501 Citation I/SP single-pilot variant was introduced in 1977. Production ended in 1985 with 689 of all variants produced. The straight wing jet is powered by JT15D turbofans. The aircraft was developed into the Citation II. Development In the early 1960s, the three major American general aviation aircraft manufacturers—Beechcraft, Cessna and Piper–faced a competitive challenge in the form of two newly-developed light business jets, the Learjet 23 and the Aero Commander 1121 Jet Commander, which were much less expensive to buy and operate than previous business jets such as the North American Sabreliner and Hawker Siddeley HS.125. Previous efforts by Beechcraft and Cess ... [...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".

North American Sabreliner
The North American Sabreliner, later sold as the Rockwell Sabreliner, is an American mid-sized business jet developed by North American Aviation. It was offered to the United States Air Force (USAF) in response to its Utility Trainer Experimental (UTX) program. It was named "Sabreliner" due to the similarity of the wing and tail to North American's F-86 Sabre jet fighter. Military variants, designated T-39 Sabreliner, were used by the USAF, United States Navy (USN), and United States Marine Corps (USMC) after the USAF placed an initial order in 1959.North American T-39A Sabreliner ". |
Citation V
The Cessna Citation V is a business jet built by Cessna. A stretched version of the Citation S/II, a Model 560 prototype flew in August 1987, it was certified on December 9, 1988, and delivered from April 1989; were delivered until 2011. The upgraded Citation Ultra was announced in September 1993, the Citation Encore upgraded with PW535 turbofans was announced in 1998, before the improved Encore+. Its US military designation is UC-35 as an executive transport and OT-47B as a drug interdiction reconnaissance aircraft. Design and development The Citation V (Model 560) is a development of the Citation S/II, retaining the supercritical airfoil and swept wing roots of that aircraft, but with a fuselage stretch and recontoured interior for increased passenger space. The passenger cabin is long, wide and high with a dropped aisle, has seven windows on each side and accommodates a four-seat club plus three chairs and a closed, belted lavatory. Maximum seating capacity is eleven ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aircraft Pilot
An aircraft pilot or aviator is a person who controls the flight of an aircraft by operating its directional flight controls. Some other aircrew members, such as navigators or flight engineers, are also considered aviators, because they are involved in operating the aircraft's navigation and engine systems. Other aircrew members, such as drone operators, flight attendants, mechanics and ground crew, are not classified as aviators. In recognition of the pilots' qualifications and responsibilities, most militaries and many airlines worldwide award aviator badges to their pilots. History The first recorded use of the term ''aviator'' (''aviateur'' in French) was in 1887, as a variation of ''aviation'', from the Latin ''avis'' (meaning ''bird''), coined in 1863 by in ''Aviation Ou Navigation Aérienne'' ("Aviation or Air Navigation"). The term ''aviatrix'' (''aviatrice'' in French), now archaic, was formerly used for a female aviator. These terms were used more in the ea ...

Thrust Reverser
Thrust reversal, also called reverse thrust, is the temporary diversion of an aircraft engine's thrust for it to act against the forward travel of the aircraft, providing deceleration. Thrust reverser systems are featured on many jet aircraft to help slow down just after touch-down, reducing wear on the brakes and enabling shorter landing distances. Such devices affect the aircraft significantly and are considered important for safe operations by airlines. There have been accidents involving thrust reversal systems, including fatal ones. Reverse thrust is also available on many propeller-driven aircraft through reversing the controllable-pitch propellers to a negative angle. The equivalent concept for a ship is called astern propulsion. Principle and uses A landing roll consists of touchdown, bringing the aircraft to taxi speed, and eventually to a complete stop. However, most commercial jet engines continue to produce thrust in the forward direction, even when idle, acti ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Beechcraft King Air
The Beechcraft King Air is a line of American utility aircraft produced by Beechcraft. The King Air line comprises a number of twin-turboprop models that have been divided into two families. The Model 90 and 100 series developed in the 1960s are known as King Airs, while the later T-tail Model 200 and 300 series were originally marketed as Super King Airs, with the name "Super" being dropped by Beechcraft in 1996 (although it is still often used to differentiate the 200 and 300 series King Airs from their smaller stablemates). The King Air was the first aircraft in its class and was produced continuously from 1964 to 2021. It outsold all of its turboprop competitors combined. It has recently faced competition from jet aircraft such as the Embraer Phenom 100, Honda HA-420 HondaJet and Cessna Citation Mustang; as well as from newer turboprop aircraft including the Piaggio P180 Avanti, and single-engine Piper Malibu Meridian, Pilatus PC-12, and Socata TBM.

Turboprop
A turboprop is a turbine engine that drives an aircraft propeller. A turboprop consists of an intake, reduction gearbox, compressor, combustor, turbine, and a propelling nozzle. Air enters the intake and is compressed by the compressor. Fuel is then added to the compressed air in the combustor, where the fuel-air mixture then combusts. The hot combustion gases expand through the turbine stages, generating power at the point of exhaust. Some of the power generated by the turbine is used to drive the compressor and electric generator. The gases are then exhausted from the turbine. In contrast to a turbojet or turbofan, the engine's exhaust gases do not provide enough energy to create significant thrust, since almost all of the engine's power is used to drive the propeller. Technological aspects Exhaust thrust in a turboprop is sacrificed in favor of shaft power, which is obtained by extracting additional power (beyond that necessary to drive the compressor) from turbine ex ...

Turbine Engine
A gas turbine, also called a combustion turbine, is a type of continuous flow internal combustion engine. The main parts common to all gas turbine engines form the power-producing part (known as the gas generator or core) and are, in the direction of flow: * a rotating gas compressor * a combustor * a compressor-driving turbine. Additional components have to be added to the gas generator to suit its application. Common to all is an air inlet but with different configurations to suit the requirements of marine use, land use or flight at speeds varying from stationary to supersonic. A propelling nozzle is added to produce thrust for flight. An extra turbine is added to drive a propeller (turboprop) or ducted fan (turbofan) to reduce fuel consumption (by increasing propulsive efficiency) at subsonic flight speeds. An extra turbine is also required to drive a helicopter rotor or land-vehicle transmission (turboshaft), marine propeller or electrical generator (power turbine). Greater ...

Piston Engine
A reciprocating engine, also often known as a piston engine, is typically a heat engine that uses one or more reciprocating pistons to convert high temperature and high pressure into a rotating motion. This article describes the common features of all types. The main types are: the internal combustion engine, used extensively in motor vehicles; the steam engine, the mainstay of the Industrial Revolution; and the Stirling engine for niche applications. Internal combustion engines are further classified in two ways: either a spark-ignition (SI) engine, where the spark plug initiates the combustion; or a compression-ignition (CI) engine, where the air within the cylinder is compressed, thus heating it, so that the heated air ignites fuel that is injected then or earlier.''Thermodynamics: An Engineering Approach'' by Yunus A. Cengal and Michael A. Boles Common features in all types There may be one or more pistons. Each piston is inside a cylinder, into which a gas is intro ...

Morane-Saulnier MS
Aéroplanes Morane-Saulnier was a French aircraft manufacturing company formed in October 1911 by Raymond Saulnier (aircraft manufacturer), Raymond Saulnier (1881–1964) and the Robert and Léon Morane, Morane brothers, Léon (1885–1918) and Robert (1886–1968). The company was taken over and diversified in the 1960s. History Model development Morane-Saulnier's first product was the Morane-Borel monoplane, a development of a monoplane design produced by the Morane company (sometimes called Type A) in partnership with Gabriel Borel). Using a wing-warping mechanism for control, this was the type in which Jules Védrines won the Paris-Madrid race on May 26, 1911. Morane-Saulnier's first commercially successful design was the Morane-Saulnier G, a wire-braced shoulder-wing monoplane with wing warping. This led to the development of a series of aircraft and was very successful in racing and setting records. The Type G was a 2-seater, and was reduced slightly in size to produ ...

Aircraft Owners And Pilots Association
The Aircraft Owners and Pilots Association (AOPA) is a Frederick, Maryland-based American non-profit political organization that advocates for general aviation. AOPA's membership consists mainly of general aviation pilots in the United States. AOPA exists to serve the interests of its members as aircraft owners and pilots and to promote the economy, safety, utility, and popularity of flight in general aviation aircraft. With 384,915 members in 2012, AOPA is the largest aviation association in the world, although it had decreased in membership from 414,224 in 2010, a loss of 7% in two years. AOPA is affiliated with other similar organizations in other countries through membership in the International Council of Aircraft Owner and Pilot Associations (IAOPA). In 2015, AOPA was inducted into the International Air & Space Hall of Fame at the San Diego Air & Space Museum. History The organization started at Wings Field in Blue Bell, Pennsylvania.
