Cessna T210N
The Cessna 210 Centurion is a six-seat, high-performance, retractable-gear, single-engined, high-wing general-aviation aircraft. First flown in January 1957, it was produced by Cessna until 1986. Design and development The early Cessna 210 (210 and 210A) had four seats with a Continental IO-470 engine of . It was essentially a Cessna 182B to which was added a retractable landing gear, swept tail, and a new wing. In 1961, the fuselage and wing were completely redesigned: The fuselage was made wider and deeper, and a third side window was added. The wing planform remained the same; constant chord from centerline to out, then straight taper to chord at from centerline, but the semi-Fowler flaps (slotted, rear-moving) were extended outboard, from wing station 100 to Wing station 122, which allowed a lower landing speed. FAA certification regulations state that a single-engined aircraft must have a flaps-down, power-off stall speed no greater than . To compensate for t ...

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. Fo ...

Chord (aeronautics)
In aeronautics, the chord is an imaginary straight line joining the leading edge and trailing edge of an aerofoil. The chord length is the distance between the trailing edge and the point where the chord intersects the leading edge. L. J. Clancy (1975), ''Aerodynamics'', Section 5.2, Pitman Publishing Limited, London. The point on the leading edge used to define the chord may be the surface point of minimum radius. p.18 For a turbine aerofoil the chord may be defined by the line between points where the front and rear of a 2-dimensional blade section would touch a flat surface when laid convex-side up. The wing, horizontal stabilizer, vertical stabilizer and propeller/rotor blades of an aircraft are all based on aerofoil sections, and the term ''chord'' or ''chord length'' is also used to describe their width. The chord of a wing, stabilizer and propeller is determined by measuring the distance between leading and trailing edges in the direction of the airflow. (If a ...

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 turb ...

Rolls-Royce Model 250
The Allison Model 250, now known as the Rolls-Royce M250, (US military designations T63 and T703) is a highly successful turboshaft engine family, originally developed by the Allison Engine Company in the early 1960s. The Model 250 has been produced by Rolls-Royce since it acquired Allison in 1995. Development In 1958, the Detroit Diesel Allison division of General Motors was chosen by the US Army to develop a new light turbine engine to power a "Light Observation Aircraft" (LOA), to replace the Cessna O-1A Bird Dog. At this stage the US Army was unsure whether to have a fixed- or rotary-wing aircraft, so Allison was instructed to consider both applications. Design studies undertaken considered a wide range of possible mechanical configurations for the turboprop/turboshaft. These studies culminated in the testing of the first prototype engine, designated YT63-A-3, in April 1959. In 1960, the US Army settled for a rotary wing platform. The YT63-A-3 first flew in a variant of t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Crownair Aviation
Swedair AB was a Swedish regional airline that existed from 1935 to 1994. It was founded as Svensk Flygtjänst AB by Tor Eliasson, who was CEO until his death in 1971. The companies last manageing director was Lars svanstrom History Crownair Swedish Ltd AB formed in 1968, state in 1969 and with Linjeflyg as half owner since 1971 bought 1975 Svensk Flygtjänst AB formed in 1935 by Tor Eliasson and then changed its name to Swedair. In 1976 the name Swedair AB was adopted. When the business was the largest in the mid-1980s, it operated 50 aircraft of various types. The taxi flight took place with two-engine Cessna, type 402, 404, 425 Corsair, 441 Conquest and in the subsidiary Basair with Learjet 35. The target flight used MU-2 and Learjet and in Vidsel three Lansen. A Douglas DC-3 was used for the CAA's control of ILS facilities.

Cessna 177 Cardinal
The Cessna 177 Cardinal is a light single-engine, high-wing general aviation aircraft produced by Cessna. It was intended to replace the Cessna 172 Skyhawk. First announced in 1967, it was produced from 1968 to 1978.Christy, Joe: ''The Complete Guide to the Single-Engine Cessnas - 3rd Edition'', pages 54-61. TAB Books, 1979. Plane and Pilot: ''1978 Aircraft Directory'', page 25. Werner & Werner Corp Publishing, 1978. Development The Cessna 177 was designed in the mid-1960s when the engineers at Cessna were asked to create a "futuristic 1970s successor to the Cessna 172". The resulting aircraft featured newer technology such as a cantilever wing lacking the lift struts of previous models, and a new laminar flow airfoil. The 177 is the only production high-wing single-engined Cessna since the Cessna 190 & 195 series to have both fixed landing gear and a cantilever wing without strut bracing. In 1971, Cessna experimented with a "Quiet Cardinal" similar to the Beechcraft QU- ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Eddy Current
Eddy currents (also called Foucault's currents) are loops of electrical current induced within conductors by a changing magnetic field in the conductor according to Faraday's law of induction or by the relative motion of a conductor in a magnetic field. Eddy currents flow in closed loops within conductors, in planes perpendicular to the magnetic field. They can be induced within nearby stationary conductors by a time-varying magnetic field created by an AC electromagnet or transformer, for example, or by relative motion between a magnet and a nearby conductor. The magnitude of the current in a given loop is proportional to the strength of the magnetic field, the area of the loop, and the rate of change of flux, and inversely proportional to the resistivity of the material. When graphed, these circular currents within a piece of metal look vaguely like eddies or whirlpools in a liquid. By Lenz's law, an eddy current creates a magnetic field that opposes the change in the magnet ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Airworthiness Directive
An Airworthiness Directive (commonly abbreviated as AD) is a notification to owners and operators of certified aircraft that a known safety deficiency with a particular model of aircraft, engine, avionics or other system exists and must be corrected. If a certified aircraft has outstanding airworthiness directives that have not been complied with, the aircraft is not considered airworthy. Thus, it is mandatory for an aircraft operator to comply with an AD. Purpose ADs usually result from service difficulty reporting by operators or from the results of aircraft accident investigations. They are issued either by the national civil aviation authority of the country of aircraft manufacture or of aircraft registration. When ADs are issued by the country of registration they are almost always coordinated with the civil aviation authority of the country of manufacture to ensure that conflicting ADs are not issued. In detail, the purpose of an AD is to notify aircraft owners: * that the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
