Fokker V.8
Fokker V.8 was a prototype five-winged aircraft built by the Fokker Aircraft Company () during the First World War for the Imperial German Army's () Imperial German Air Service (). The aircraft was dangerously unstable and performed very poorly. It was scrapped after two flights. Development After the initial success of the Fokker Dr.I triplane, Anthony Fokker proposed a quintuplane in late 1917, reasoning that if three wings were good, five would be even better. Reinhold Platz, chief engineer for Fokker, objected, but Fokker ordered the aircraft to be built regardless. The fuselage of the V.6 was lengthened and the three wings from a Dr.I were placed at the extreme front of the aircraft with the Mercedes D.III engine positioned between the upper and middle wings. A upper pair of Dr.I wings were added midway along the fuselage with their leading edges virtually even with the aft end of the cockpit coaming. Balanced control surfaces were fitted to the upper wings, those at the fr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fokker
Fokker (; ) was a Dutch aircraft manufacturer that operated from 1912 to 1996. The company was founded by the Dutch aviator Anthony Fokker and became famous during World War I for its fighter aircraft. During its most successful period in the 1920s and 1930s, Fokker dominated the civil aviation market. The company's fortunes declined over the course of the late 20th century; it declared bankruptcy in 1996, and its operations were sold to competitors. History Fokker in Germany At age 20, while studying in Germany, Anthony Fokker built his initial aircraft, the Fokker Spin, ''Spin'' (Spider)—the first Dutch-built plane to fly in his home country. Taking advantage of better opportunities in Germany, he moved to Berlin, where in 1912, he founded his first company, Fokker Aeroplanbau, later moving to the Görries suburb just southwest of Schwerin (at ), where the current company was founded, as Fokker Aviatik GmbH, on 12 February 1912.

Leading Edge
The leading edge is the part of the wing that first contacts the air;Crane, Dale: ''Dictionary of Aeronautical Terms, third edition'', page 305. Aviation Supplies & Academics, 1997. alternatively it is the foremost edge of an airfoil section. The first is an aerodynamic definition, the second a structural one. As an example of the distinction, during a tailslide, from an aerodynamic point of view, the trailing edge becomes the leading edge and vice versa but from a structural point of view the leading edge remains unchanged. Overview The structural leading edge may be equipped with one or more of the following: * Leading edge boots * Leading edge cuffs * Leading edge extensions * Leading edge slats * Leading edge slots * Krueger flaps * Stall strips * Vortex generators. Associated terms are leading edge radius and leading edge stagnation point. Seen in plan the leading edge may be straight or curved. A straight leading edge may be swept or unswept, the latter meanin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tandem-wing Aircraft
image:qac.quickie.q2.g-bspa.flying.arp.jpg, QAC Quickie Q2 A tandem wing is a wing configuration in which a flying craft or animal has two or more sets of wings set one behind another. All the wings contribute to lift (force), lift. The tandem wing is distinct from the biplane in which the wings are stacked one above another, or from the canard (aeronautics), canard or "tail-first" configuration where the forward surface is much smaller and does not contribute significantly to the overall lift. In aviation, tandem wings have long been experimented with, but few designs have ever been put into production. Tandem wings in nature occur only in insects and flying fish, although in the past there have been tandem-wing flying reptiles. Design principles A tandem wing wing configuration, configuration has two main wing planes, with one located forward and the other to the rear. The difference is greater than the wing chord, so there is a clear gap between them and the aircraft centre ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

1910s German Experimental Aircraft
Year 191 ( CXCI) was a common year starting on Friday of the Julian calendar. At the time, it was known as the Year of the Consulship of Apronianus and Bradua (or, less frequently, year 944 ''Ab urbe condita''). The denomination 191 for this year has been used since the early medieval period, when the Anno Domini calendar era became the prevalent method in Europe for naming years. Events By place Parthia * King Vologases IV of Parthia dies after a 44-year reign, and is succeeded by his son Vologases V. China * A coalition of Chinese warlords from the east of Hangu Pass launches a punitive campaign against the warlord Dong Zhuo, who seized control of the central government in 189, and held the figurehead Emperor Xian hostage.

Center Of Lift
In fluid mechanics, the center of pressure is the point on a body where a single force acting at that point can represent the total effect of the pressure field acting on the body. The total force vector acting at the center of pressure is the surface integral of the pressure vector field across the surface of the body. The resultant force and center of pressure location produce an equivalent force and moment on the body as the original pressure field. Pressure fields occur in both static and dynamic fluid mechanics. Specification of the center of pressure, the reference point from which the center of pressure is referenced, and the associated force vector allows the moment generated about any point to be computed by a translation from the reference point to the desired new point. It is common for the center of pressure to be located on the body, but in fluid flows it is possible for the pressure field to exert a moment on the body of such magnitude that the center of pressur ...

Elevator (aircraft)
Elevators are flight control surfaces, usually at the rear of an aircraft, which control the aircraft's pitch, and therefore the angle of attack and the lift of the wing. The elevators are usually hinged to the tailplane or horizontal stabilizer. They may be the only pitch control surface present, and are sometimes located at the front of the aircraft (early airplanes and canards) or integrated into a rear "all-moving tailplane", also called a slab elevator or stabilator. Elevator control effectiveness The elevator is a usable up and down system that controls the plane, horizontal stabilizer usually creates a ''downward'' force which balances the nose down moment created by the wing lift force, which typically applies at a point (the wing center of lift) situated aft of the airplane's center of gravity. The effects of drag and changing the engine thrust may also result in pitch moments that need to be compensated with the horizontal stabilizer. Both the horizontal ...

Ailerons
An aileron (French for "little wing" or "fin") is a hinged flight control surface usually forming part of the trailing edge of each wing of a fixed-wing aircraft. Ailerons are used in pairs to control the aircraft in roll (or movement around the aircraft's longitudinal axis), which normally results in a change in flight path due to the tilting of the lift vector. Movement around this axis is called rolling or banking. Considerable controversy exists over credit for the invention of the aileron. The Wright brothers and Glenn Curtiss fought a years-long legal battle over the Wright patent of 1906, which described a method of wing-warping to achieve lateral control. The brothers prevailed in several court decisions which found that Curtiss's use of ailerons violated the Wright patent. Ultimately, the First World War compelled the U.S. Government to legislate a legal resolution. A much earlier aileron concept was patented in 1868 by British scientist Matthew Piers Watt Boulton ...

Cockpit
A cockpit or flight deck is the area, on the front part of an aircraft, spacecraft, or submersible, from which a pilot controls the vehicle. The cockpit of an aircraft contains flight instruments on an instrument panel, and the controls that enable the pilot to fly the aircraft. In most airliners, a door separates the cockpit from the aircraft cabin. After the September 11, 2001 attacks, all major airlines fortified their cockpits against access by hijackers. Etymology The word cockpit seems to have been used as a nautical term in the 17th century, without reference to cock fighting. It referred to an area in the rear of a ship where the cockswain's station was located, the cockswain being the pilot of a smaller "boat" that could be dispatched from the ship to board another ship or to bring people ashore. The word "cockswain" in turn derives from the old English terms for "boat-servant" (''coque'' is the French word for "shell"; and ''swain'' was old English for boy ...
