Deperdussin Monocoque
The Deperdussin Monocoque was an early racing aircraft built in 1912 by the Aéroplanes Deperdussin, a French aircraft manufacturer started in 1911 and reorganized as the Société Pour L'Aviation et ses Dérivés ( SPAD) in 1913. It is so named because of the method of construction of its fuselage. The aircraft is noted for winning the Gordon Bennett Trophy in 1912 and 1913, and for raising the world speed record for aircraft to . Background The first use of monocoque construction in aviation is attributed to Eugene Ruchonnet, a Swiss marine engineer who had built an aircraft nicknamed the ''Cigare'' in 1911, which had a fuselage constructed by building up several layers of thin wood, each lamination being applied at right angle to the one underneath. The usual method of construction of an aircraft's fuselage at this time was to use a wire braced box-girder covered in fabric. Ruchonnet's technique, in which the outer surface of the structure is load-bearing, would become the ... [...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.

Pfalz Flugzeugwerke
Pfalz Flugzeugwerke was a World War I German aircraft manufacturer, located at the Speyer airfield in the Palatinate (German: Pfalz). They are best known for their series of fighters, notably the Pfalz D.III and Pfalz D.XII. The company went bankrupt after the Armistice, when the French occupation forces confiscated all of the equipment, but the factory was re-used by various other companies until re-forming in 1997. Today they are a parts manufacturer referred to as PFW. Early history Pfalz was the brainchild of Alfred Eversbusch, son of a foundry owner in Neustadt an der Weinstraße. It appears that he had built his own aircraft between 1912 and 1913, although the exact origin of the design is unclear. On June 3, 1913, the Pfalz company was registered, consisting of Alfred, his brother Ernst, and his brother-in-law Willy Sabersky-Müssigbrodt, as well as several investors: Richard and Eugen Kahn, and August Kahn (unrelated). They initially proposed to build designs from A ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
The 39 Steps (1978 Film)
''The Thirty Nine Steps'' is a British 1978 thriller film directed by Don Sharp, with screenplay by British playwright Michael Robson, based on the novel '' The Thirty-Nine Steps'' by John Buchan. It was the third film version of the 1915 novel. This version of Buchan's tale starred Robert Powell as Richard Hannay, Karen Dotrice as Alex, John Mills as Colonel Scudder, and a host of other well-known British actors in smaller parts. It is generally regarded as the closest to the novel, being set before the Great War. The early events and overall feel of the film bear much resemblance to Buchan's original story, albeit with a few changes such as the re-casting of Scudder as a more immediately sympathetic character and the introduction of a love interest. It also introduces a different meaning for the "thirty-nine steps", although unlike its filmed predecessors it returns to Buchan's original notion of being an actual staircase. It is known for the Big Ben sequence near the end, in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Eugène Gilbert
Sous Lieutenant Eugène Gilbert (19 July 1889 – 17 May 1918) was a World War I flying ace credited with five aerial victories. He had also been a famous pioneer wikt:pre-war, pre-war racing pilot, flying in many countries throughout Europe. Biography Gilbert was born on 19 July 1889 in Riom, France. His mother, Henriette Françoise Gilbert was the daughter of a public works contractor; his father is unknown. He became interested in flight in his teens and attempted to build his own version of a flying machine around 1909. The effort appears to have been unsuccessful. That same year he entered the Bleriot flight school in Étampes, gaining his pilot's license on 24 September 1910 In 1911 Gilbert was called up for military service and with only eight flying lessons made a corporal-aviator. He was forced to leave the army after six months of service following a serious accident during a maneuver, and launched himself at once in sporting competitions where he quickly distinguishe ...

Propeller (aircraft)
An aircraft propeller, also called an airscrew,Beaumont, R.A.; ''Aeronautical Engineering'', Odhams, 1942, Chapter 13, "Airscrews". converts rotary motion from an engine or other power source into a swirling slipstream which pushes the propeller forwards or backwards. It comprises a rotating power-driven hub, to which are attached several radial airfoil-section blades such that the whole assembly rotates about a longitudinal axis. The blade pitch may be fixed, manually variable to a few set positions, or of the automatically variable "constant-speed" type. The propeller attaches to the power source's driveshaft either directly or through reduction gearing. Propellers can be made from wood, metal or composite materials. Propellers are most suitable for use at subsonic airspeeds generally below about , although supersonic speeds were achieved in the McDonnell XF-88B experimental propeller-equipped aircraft. Supersonic tip-speeds are used in some aircraft like the Tupolev Tu-95, w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Spinner (aircraft)
A spinner is an aircraft component, a streamlined fairing fitted over a propeller hub or at the centre of a turbofan engine. Spinners both make the aircraft overall more streamlined, thereby reducing aerodynamic drag, and also smooth the airflow so that it enters the air intakes more efficiently. Spinners also fulfill an aesthetic role on some aircraft designs.Crane, Dale: ''Dictionary of Aeronautical Terms, third edition'', page 480. Aviation Supplies & Academics, 1997. Bingelis, Tony: ''Bingelis on Engines'', pages 196-210. Experimental Aircraft Association Aviation Foundation, 1995. Bingelis, Tony: ''Firewall Forward'', pages 269-273. Experimental Aircraft Association Aviation Foundation, 1992. Piston engine spinners Piston-powered aircraft often have spinners of one of two basic designs. The ''large spinner'' fits over the propeller, while the smaller ''skull cap'' style is directly attached to the propeller and just covers the propeller mounting bolts. The spinner may be co ...

Tulipwood
Most commonly, tulipwood is the greenish yellowish wood yielded from the tulip tree, found on the Eastern side of North America and a similar species in some parts of China. In the United States, it is commonly known as tulip poplar or yellow poplar, even though the tree is not related to the poplars. It is notable for its height, which can exceed 190 feet. The wood is very light, around 490 kg per cubic meter, but very strong and is used in many applications, including furniture, joinery and moldings. It can also be stained very easily and is often used as a low-cost alternative to walnut and cherry in furniture and doors. Other types Brazilian Brazilian tulipwood is a different species. A classic high-quality wood, it is very dense with a lovely figure. It is used for inlays in furniture and for small turned items. Available only in small sizes, it is rarely used in the solid for luxury furniture. Like other woods with a pronounced figure it is rather strongly subject ...

Pine
A pine is any conifer tree or shrub in the genus ''Pinus'' () of the family Pinaceae. ''Pinus'' is the sole genus in the subfamily Pinoideae. The World Flora Online created by the Royal Botanic Gardens, Kew and Missouri Botanical Garden accepts 187 species names of pines as current, together with more synonyms. The American Conifer Society (ACS) and the Royal Horticultural Society accept 121 species. Pines are commonly found in the Northern Hemisphere. ''Pine'' may also refer to the lumber derived from pine trees; it is one of the more extensively used types of lumber. The pine family is the largest conifer family and there are currently 818 named cultivars (or trinomials) recognized by the ACS. Description Pine trees are evergreen, coniferous resinous trees (or, rarely, shrubs) growing tall, with the majority of species reaching tall. The smallest are Siberian dwarf pine and Potosi pinyon, and the tallest is an tall ponderosa pine located in southern Oregon's Rogue Riv ...

Rib (aircraft)
In an aircraft, ribs are forming elements of the structure of a wing, especially in traditional construction. By analogy with the anatomical definition of " rib", the ribs attach to the main 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, 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 profiles that are joined together. These joints requ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fraxinus
''Fraxinus'' (), common name, commonly called ash, is a genus of flowering plants in the olive and lilac family, Oleaceae. It contains 45–65 species of usually medium to large trees, mostly deciduous, though a number of Subtropics, subtropical species are evergreen. The genus is widespread across much of Europe, Asia, and North America. The leaf, leaves are opposite leaves, opposite (rarely in Whorl (botany), whorls of three), and mostly pinnate, pinnately compound, though simple in a few species. The seeds, popularly known as "keys" or "helicopter seeds", are a type of fruit known as a samara (fruit), samara. Some ''Fraxinus'' species are Dioecy, dioecious, having male and female flowers on separate plants but sex in ash is expressed as a continuum between male and female individuals, dominated by unisexual trees. With age, ash may change their sexual function from predominantly male and hermaphrodite towards femaleness ; if grown as an ornamental and both sexes are present, ...
