Aircraft Hull
The fuselage (; from the French ''fuselé'' "spindle-shaped") is an aircraft's main body section. It holds crew, passengers, or cargo. In single-engine aircraft, it will usually contain an engine as well, although in some amphibious aircraft the single engine is mounted on a pylon attached to the fuselage, which in turn is used as a floating hull. The fuselage also serves to position the control and stabilization surfaces in specific relationships to lifting surfaces, which is required for aircraft stability and maneuverability. Types of structures Truss structure This type of structure is still in use in many lightweight aircraft using welded steel tube trusses. A box truss fuselage structure can also be built out of wood—often covered with plywood. Simple box structures may be rounded by the addition of supported lightweight stringers, allowing the fabric covering to form a more aerodynamic shape, or one more pleasing to the eye.

Vickers
Vickers was a British engineering company that existed from 1828 until 1999. It was formed in Sheffield as a steel foundry by Edward Vickers and his father-in-law, and soon became famous for casting church bells. The company went public in 1867, acquired more businesses, and began branching out into military hardware and shipbuilding. In 1911, the company expanded into aircraft manufacturer, aircraft manufacture and opened a flying school. They expanded even further into electrical and railway manufacturing, and in 1928 acquired an interest in the Supermarine. Beginning in the 1960s, various parts of the company were nationalised, and in 1999 the rest of the company was acquired by Rolls-Royce Holdings, Rolls-Royce plc, who sold the defence arm to Alvis plc. The Vickers name lived on in Alvis Vickers, until the latter was acquired by BAE Systems in 2004 to form BAE Systems Platforms & Services, BAE Systems Land Systems.

Boeing 787
The Boeing 787 Dreamliner is an American wide-body jet airliner developed and manufactured by Boeing Commercial Airplanes. After dropping its unconventional Sonic Cruiser project, Boeing announced the conventional 7E7 on January 29, 2003, which focused largely on efficiency. The program was launched on April 26, 2004, with an order for 50 aircraft from All Nippon Airways (ANA), targeting a 2008 introduction. On July 8, 2007, a prototype 787 was rolled out without major operating systems, and then the aircraft experienced multiple delays until its maiden flight on December 15, 2009. Type certification was received in August 2011 and the first 787-8 was delivered in September 2011 before entering commercial service on October 26, 2011, with ANA. At launch, Boeing targeted the 787 with 20% less fuel burn than replaced aircraft like the Boeing 767, carrying 200 to 300 passengers on point-to-point routes up to , a shift from hub-and-spoke travel. The twinjet is powered by ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sailplane
A glider or sailplane is a type of glider aircraft used in the leisure activity and sport of gliding (also called soaring). This unpowered aircraft can use naturally occurring currents of rising air in the atmosphere to gain altitude. Sailplanes are aerodynamically streamlined and so can fly a significant distance forward for a small decrease in altitude. In North America the term 'sailplane' is also used to describe this type of aircraft. In other parts of the English-speaking world, the word 'glider' is more common. Types Gliders benefit from producing the least drag for any given amount of lift, and this is best achieved with long, thin wings, a slender fuselage and smooth surfaces with an absence of protuberances. Aircraft with these features are able to soar – climb efficiently in rising air produced by thermals or hills. In still air, sailplanes can glide long distances at high speed with a minimum loss of height in between. Sailplanes have rigid wings and either ...

Monocoque
Monocoque ( ), also called structural skin, is a structural system in which loads are supported by an object's external skin, in a manner similar to an egg shell. The word ''monocoque'' is a French term for "single shell". First used for boats, a true monocoque carries both tensile and compressive forces within the skin and can be recognised by the absence of a load-carrying internal frame. Few metal aircraft other than those with milled skins can strictly be regarded as pure monocoques, as they use a metal shell or sheeting reinforced with frames riveted to the skin, but most wooden aircraft are described as monocoques, even though they also incorporate frames. By contrast, a semi-monocoque is a hybrid combining a tensile stressed skin and a compressive structure made up of longerons and ribs or frames. Other semi-monocoques, not to be confused with true monocoques, include vehicle unibodies, which tend to be composites, and inflatable shells or balloon tanks, both of which ...

De Havilland Mosquito
The de Havilland DH.98 Mosquito is a British twin-engined, shoulder-winged, multirole combat aircraft, introduced during the Second World War. Unusual in that its frame was constructed mostly of wood, it was nicknamed the "Wooden Wonder", or "Mossie". Lord Beaverbrook, Minister of Aircraft Production, nicknamed it "Freeman's Folly", alluding to Air Chief Marshal Sir Wilfrid Freeman, who defended Geoffrey de Havilland and his design concept against orders to scrap the project. In 1941, it was one of the fastest operational aircraft in the world.Bowman 2005, p. 21. Originally conceived as an unarmed fast bomber, the Mosquito's use evolved during the war into many roles, including low- to medium-altitude daytime tactical bomber, high-altitude night bomber, pathfinder, day or night fighter, fighter-bomber, intruder, maritime strike, and photo-reconnaissance aircraft. It was also used by the British Overseas Airways Corporation as a fast transport to carry small, high-value c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rutan VariEze
The Rutan VariEze is a composite, canard aircraft designed by Burt Rutan. It is a high-performance homebuilt aircraft, hundreds of which have been constructed. The design later evolved into the Long-EZ and other, larger cabin canard aircraft. The VariEze is notable for popularizing the canard configuration and moldless glass cloth composite construction for homebuilt aircraft. Overview Work on the VariEze design, which grew out of Rutan's experience designing and building the VariViggen, began in 1974. The first prototype, designated Model 31 and registered N7EZ, first flew on May 21, 1975 after four months of construction. This aircraft used a Volkswagen engine conversion. Three months later it was shown at Oshkosh where Dick Rutan piloted it to an under 500 kg class distance record of . Rutan believed that by engaging in a program of breaking class records he could further fine-tune the design. The aircraft was so popular at Oshkosh that Rutan redesigned the airc ...

Glass-reinforced Plastic
Fiberglass (American English) or fibreglass (Commonwealth English) is a common type of fiber-reinforced plastic using glass fiber. The fibers may be randomly arranged, flattened into a sheet called a chopped strand mat, or woven into glass cloth. The plastic matrix may be a thermoset polymer matrix—most often based on thermosetting polymers such as epoxy, polyester resin, or vinyl ester resin—or a thermoplastic. Cheaper and more flexible than carbon fiber, it is stronger than many metals by weight, non-magnetic, non-conductive, transparent to electromagnetic radiation, can be molded into complex shapes, and is chemically inert under many circumstances. Applications include aircraft, boats, automobiles, bath tubs and enclosures, swimming pools, hot tubs, septic tanks, water tanks, roofing, pipes, cladding, orthopedic casts, surfboards, and external door skins. Other common names for fiberglass are glass-reinforced plastic (GRP), glass-fiber reinforced plastic (GFRP) or GFK ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Molding (process)
Molding (American English) or moulding (British and Commonwealth English; see spelling differences) is the process of manufacturing by shaping liquid or pliable raw material using a rigid frame called a mold or matrix. This itself may have been made using a pattern or model of the final object. A mold or mould is a hollowed-out block that is filled with a liquid or pliable material such as plastic, glass, metal, or ceramic raw material. The liquid hardens or sets inside the mold, adopting its shape. A mold is a counterpart to a cast. The very common bi-valve molding process uses two molds, one for each half of the object. Articulated molds have multiple pieces that come together to form the complete mold, and then disassemble to release the finished casting; they are expensive, but necessary when the casting shape has complex overhangs. Piece-molding uses a number of different molds, each creating a section of a complicated object. This is generally only used for larger a ...

Plywood
Plywood is a material manufactured from thin layers or "plies" of wood veneer that are glued together with adjacent layers having their wood grain rotated up to 90 degrees to one another. It is an engineered wood from the family of manufactured boards which include medium-density fibreboard (MDF), oriented strand board (OSB) and particle board (chipboard). All plywoods bind resin and wood fibre sheets (cellulose cells are long, strong and thin) to form a composite material. This alternation of the grain is called ''cross-graining'' and has several important benefits: it reduces the tendency of wood to split when nailed at the edges; it reduces expansion and shrinkage, providing improved dimensional stability; and it makes the strength of the panel consistent across all directions. There is usually an odd number of plies, so that the sheet is balanced—this reduces warping. Because plywood is bonded with grains running against one another and with an odd number of composite part ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lockheed Vega
The Lockheed Vega is an American five- to seven-seat high-wing monoplane airliner built by the Lockheed Corporation starting in 1927. It became famous for its use by a number of record-breaking pilots who were attracted to the rugged and very long-range design. Amelia Earhart became the first woman to fly solo across the Atlantic Ocean in one, and Wiley Post used his to prove the existence of the jet stream after having flown around the world twice. Design and development Designed by John Knudsen Northrop and Gerald Vultee, both of whom would later form their own companies, the aircraft was originally intended to serve with Lockheed's own airline routes. They set out to build a four-passenger (plus pilot) aircraft that was not only rugged but also one of the fastest aircraft of its era. Using a wooden monocoque fuselage, plywood-covered cantilever wings and the best engine available, the Vega delivered on the promise of speed. The fuselage was built from sheets of plywood, ski ...

Vans
Vans is an American manufacturer of skateboarding shoes and related apparel, established in Anaheim, California, and owned by VF Corporation. The company also sponsors surf, snowboarding, BMX, and motocross teams. From 1996 to 2019, the company was the primary sponsor of the annual Warped Tour music festival. History Paul Van Doren; his brother, James; and Gordon C. Lee opened the first Vans store as "The Van Doren Rubber Company" on March 16, 1966, at 704 East Broadway in Anaheim, California. The business manufactured shoes and sold them directly to the public. Upon opening, twelve customers purchased Vans deck shoes (now called "Authentic"), similar to those manufactured by Keds but with a thicker sole. The store had display models of three styles of shoes, priced between US$2.49 and US$4.99, but did not have any inventory ready to sell and Paul Van Doren did not have change to give customers; customers took their shoes home and came back the next day to pay.
