American Champion Scout
The 8GCBC Scout is a two-seat, high-wing, single-engined fixed conventional gear general aviation airplane that entered production in the United States in 1974. Designed for personal and commercial use, it is commonly found in utility roles such as bush flying—thanks to its short takeoff and landing (STOL) ability—as well as agriculture, pipeline patrol, and glider and banner towing. Development The Scout was designed and initially produced by Bellanca Aircraft Corporation, and is a derivative of the 7-series Citabrias and 8KCAB Decathlon; Bellanca had been building these designs since receiving them in the acquisition of Champion Aircraft Corporation in 1970. The Scout is one of two wholly Bellanca-developed contributions to these aircraft series, and is also one of only two airplanes Bellanca produced in the 7 and 8 series not certified for aerobatics. (The other model, in both categories, is the 7ACA.) The Scout carries the model designation 8GCBC, which makes i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
WikiProject Aircraft
A WikiProject, or Wikiproject, is an affinity group for contributors with shared goals within the Wikimedia movement. WikiProjects are prevalent within the largest wiki, Wikipedia, and exist to varying degrees within Wikimedia project, sibling projects such as Wiktionary, Wikiquote, Wikidata, and Wikisource.

Champion Aircraft (Texas)
Champion Aircraft Corporation was an aircraft manufacturer founded by Robert "Bob" Brown that purchased the design for the Aeronca Champion, a light aircraft previously built by the Aeronca Aircraft Corporation, in 1954. Through the 1950s and the 1960s Champion introduced variations on the 7-series design. Champion also developed and began production of the significantly upgraded follow-on to the 7-series, the 8KCAB Decathlon, as well as the twin-engined Lancer. Champion was acquired in 1970 by Bellanca Aircraft Corporation, which continued to produce the Champion aircraft line at the former Champion plant. Aircraft Champion was originally Flyers Service Inc., an aircraft maintenance company headed by Robert "Bob" Brown and located at Holman Field in Saint Paul, Minnesota. In 1954, the company purchased the type certificate for the Aeronca Champion design from Aeronca, and changed its name and realigned its focus to manufacturing the Champion line of aircraft.

Flap (aircraft)
A flap is a high-lift device used to reduce the stall (flight), stalling speed of an aircraft wing at a given weight. Flaps are usually mounted on the wing trailing edges of a fixed-wing aircraft. Flaps are used to reduce the take-off distance and the landing distance. Flaps also cause an increase in Drag (physics), drag so they are retracted when not needed. The flaps installed on most aircraft are partial-span flaps; spanwise from near the wing root to the inboard end of the ailerons. When partial-span flaps are extended they alter the spanwise lift distribution on the wing by causing the inboard half of the wing to supply an increased proportion of the lift, and the outboard half to supply a reduced proportion of the lift. Reducing the proportion of the lift supplied by the outboard half of the wing is accompanied by a reduction in the angle of attack on the outboard half. This is beneficial because it increases the margin above the Stall (fluid dynamics), stall of the outbo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wingspan
The wingspan (or just span) of a bird or an airplane is the distance from one wingtip to the opposite wingtip. For example, the Boeing 777–200 has a wingspan of , and a wandering albatross (''Diomedea exulans'') caught in 1965 had a wingspan of , the official record for a living bird. The term wingspan, more technically 'extent' , is also used for other winged animals such as pterosaurs, bats, insects, etc., and other aircraft such as ornithopters. In humans, the term wingspan also refers to the arm span, which is the distance between the length from the end of an individual's arm (measured at the fingertips) to the individual's fingertips on the other arm when raised parallel to the ground at shoulder height. Wingspan of aircraft The wingspan of an aircraft is always measured in a straight line, from wingtip to wingtip, regardless of wing shape or sweep. Implications for aircraft design and animal evolution The lift from wings is proportional to their area, so the h ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Spar (aviation)
In a fixed-wing aircraft, the spar is often the main structural member of the wing, running wingspan, spanwise at right angles (or thereabouts depending on Swept wing, wing sweep) to the fuselage. The spar carries flight Structural load, loads and the weight of the wings while on the ground. Other structural and forming members such as Rib (aircraft), ribs may be attached to the spar or spars, with stressed skin construction also sharing the loads where it is used. There may be more than one spar in a wing or none at all. Where a single spar carries most of the force, it is known as the main spar. Spars are also used in other aircraft airfoil, aerofoil surfaces such as the tailplane and Vertical stabilizer, fin and serve a similar function, although the loads transmitted may be different from those of a wing spar. Spar loads The wing spar provides the majority of the weight support and dynamic load integrity of cantilever monoplanes, often coupled with the strength of the wing D- ...

Rib (aircraft)
In an aircraft, ribs are forming elements of the airframe structure of a wing, especially in traditional construction. By analogy with the anatomical definition of "rib", the ribs attach to the main Spar (aviation), spar, and by being repeated at frequent intervals, form a skeletal shape for the wing. Usually ribs incorporate the airfoil shape of the wing, and the skin adopts this shape when stretched over the ribs. Type of ribs There are several types of ribs. Form-ribs, plate-type ribs, truss ribs, closed-ribs, forged ribs and milled ribs, where form-ribs are used for light to medium loading and milled ribs offer the greatest strength. * Form-ribs are made from a sheet of metal bent into shape, such as a U-profile. This profile is placed on the skin, just like a stringer (aircraft), stringer, but then in the other direction. * Plate-type ribs consist of sheet-metal, which has upturned edges and (often has) weight-saving holes cut into it. * Truss ribs are built up out of profi ...

Aluminum Alloy
An aluminium alloy ( UK/IUPAC) or aluminum alloy ( NA; see spelling differences) is an alloy in which aluminium (Al) is the predominant metal. The typical alloying elements are copper, magnesium, manganese, silicon, tin, nickel and zinc. There are two principal classifications, namely casting alloys and wrought alloys, both of which are further subdivided into the categories heat-treatable and non-heat-treatable. About 85% of aluminium is used for wrought products, for example rolled plate, foils and extrusions. Cast aluminium alloys yield cost-effective products due to their low melting points, although they generally have lower tensile strengths than wrought alloys. The most important cast aluminium alloy system is Al–Si, where the high levels of silicon (4–13%) contribute to give good casting characteristics. Aluminium alloys are widely used in engineering structures and components where light weight or corrosion resistance is required.I. J. Polmear, ''Light Alloys'', A ...

Wing
A wing is a type of fin that produces both Lift (force), lift and drag while moving through air. Wings are defined by two shape characteristics, an airfoil section and a planform (aeronautics), planform. Wing efficiency is expressed as lift-to-drag ratio, which compares the benefit of lift with the air resistance of a given wing shape, as it flies. Aerodynamics is the study of wing performance in air. Equivalent Foil (fluid mechanics), foils that move through water are found on Hydrofoil, hydrofoil power vessels and Sailing hydrofoil, foiling sailboats that lift out of the water at speed and on submarines that use diving planes to point the boat upwards or downwards, while running submerged. Hydrodynamics is the study of foil performance in water. Etymology and usage The word "wing" from the Old Norse ''vængr'' for many centuries referred mainly to the foremost limb (anatomy), limbs of birds (in addition to the architectural aisle). But in recent centuries the word's meaning ha ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aeronca C-2
The Aeronca C-2 is an American light monoplane designed by Jean A. Roche and built by Aeronca Aircraft. Development Roche Monoplane Jean A. Roche was a U.S. Army engineer at McCook Field airfield in Dayton, Ohio. Roche developed an aircraft with automatic stability and was granted U. S. Patent No. 1,085,461. Roche published his engineering ideas for the aircraft in Aerial Age Weekly and Slipstream Monthly magazines. The prototype was started in Ohio in 1923 with the assistance of fellow engineer Quinten Dohse. The aircraft used a triangular cross-section welded steel tube fuselage, with wood wings, was fabric-covered, and used wire bracing throughout. A Henderson engine was installed, but did not perform well. Next a custom 29 hp two-cylinder Morehouse engine was developed for the aircraft. On September 1, 1925, the aircraft was successfully test flown. Many pilots including Jimmy Doolittle tried out the aircraft. Wright Aeronautical hired Morehouse and rights to his ...

Longeron
In engineering, a longeron or stringer is a load-bearing component of a framework. The term is commonly used in connection with aircraft fuselages and automobile chassis. Longerons are used in conjunction with stringers to form structural frameworks. Aircraft In an aircraft fuselage, stringers are attached to formers (also called frames) and run in the longitudinal direction of the aircraft. They are primarily responsible for transferring the aerodynamic loads acting on the skin onto the frames and formers. In the wings or horizontal stabilizer, longerons run spanwise (from wing root to wing tip) and attach between the ribs. The primary function here also is to transfer the bending loads acting on the wings onto the ribs and spar. The terms "longeron" and "stringer" are sometimes used interchangeably. Historically, though, there is a subtle difference between the two terms. If the longitudinal members in a fuselage are few in number (usually 4 to 8) and run all along the ...

Former
A former is an object, such as a template, gauge or cutting die, which is used to form something such as a boat's hull. Typically, a former gives shape to a structure that may have complex curvature. A former may become an integral part of the finished structure, as in an aircraft fuselage, or it may be removable, being used in the construction process and then discarded or re-used. Aircraft formers Formers are used in the construction of aircraft fuselage, of which a typical fuselage has a series from the nose cone to the empennage, typically perpendicular to the longitudinal axis of the aircraft. The primary purpose of formers is to establish the shape of the fuselage and reduce the column length of stringers to prevent instability. Formers are typically attached to longerons, which support the skin of the aircraft. The "former-and-longeron" technique (also called stations and stringers) was adopted from boat construction, and was typical of light aircraft built until t ...

Empennage
The empennage ( or ), also known as the tail or tail assembly, is a structure at the rear of an aircraft that provides stability during flight, in a way similar to the feathers on an arrow.Crane, Dale: ''Dictionary of Aeronautical Terms, third edition'', p. 194. Aviation Supplies & Academics, 1997. Aviation Publishers Co. Limited, ''From the Ground Up'', p. 10 (27th revised edition) The term derives from the French language verb which means " to feather an arrow". Most aircraft feature an empennage incorporating vertical and horizontal stabilising surfaces which stabilise the flight dynamics of yaw and pitch, as well as housing control surfaces. In spite of effective control surfaces, many early aircraft that lacked a stabilising empennage were virtually unflyable. Even so-called "tailless aircraft" usually have a tail fin (usually a vertical stabiliser). Heavier-than-air aircraft without any kind of empennage (such as the Northrop B-2) are rare, and generally use specially ...
