Carley C.12
The Carley C.12 was a small Dutch single seat sporting monoplane from the 1920s. There were several developments but only small numbers were produced. Design and development Like his earlier Carley S.1, Joop Carley's C.12 was a compact single seat monoplane with a shoulder wing. It differed by being much lighter and all of the several engines fitted were much less powerful than the S.1's 37 kW (50 hp) Gnôme. The wing of the C.12 was a cantilever, thick aerofoil section, low aspect ratio structure built around two wooden box spars, covered with three-ply ahead of the forward spar and fabric behind. The C.12's fuselage was constructed around three wooden longerons and 3-ply bulkheads, giving it a triangular cross section and entirely plywood covered. The cockpit, within a circular cut-out in the wing, placed the pilot high between the wing spars giving him a good forward view. There were sizeable cut-outs in the wing trailing edge to improve his rearward view down ... [...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.

Cockpit
A cockpit or flight deck is the area, usually near the front of an aircraft or spacecraft, from which a Pilot in command, pilot controls the aircraft. 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 attacks, September 11, 2001 attacks, all major airlines Airport_security_repercussions_due_to_the_September_11_attacks#Improved_security_on_aircraft, fortified their cockpits against access by aircraft hijacking, hijackers. Etymology The word cockpit seems to have been cockpit (sailing), 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.

Pander & Son
Pander & Son was a Dutch aircraft company based in The Hague, founded by Harmen Pander and his son Henk Pander. History Harmen Pander was the managing director of a furniture company which in 1924 bought the assets of the bankrupt ''Vliegtuig Industrie Holland'' (VIH) company, which included the services of designers Theodorus Egbert Slot and H. Van der Kwast. Pander set up the ''Nederlandse Fabriek van Vliegtuigen H. Pander & Zonen'' ("H. Pander and Son Dutch Aircraft Company") and began construction of an improved version of the VIH Holland H.2, renamed the Pander D. In 1929 the German sailplane builder Alexander Lippisch came to the Netherlands prompting Theo Slot to build the first Dutch glider in 1930. This aircraft, the P-1 ''Zögling'', was a copy of the Stamer and Lippisch Z-12 ''Zögling''. The company built a small number of trainer and sporting aircraft, perhaps the most well-known aircraft being the Pander S4 Postjager, designed by Theo Slot. The design was suggeste ...

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] |
Anzani 3-cylinder Fan Engines
From 1905 to 1915, Alessandro Anzani built a number of three-cylinder fan engines and radial engines, one of which powered Louis Blériot's 1909 cross-channel flight. An Anzani three-cylinder engine that powers a Blériot XI based in England is thought to be the oldest airworthy engine in the world. Design and development Alessandro Anzani began building motorcycle engines in France around 1905. Unusually, his motors were air-cooled rather than water-cooled, making them light. His first designs were two-cylinder V-engines, and he rode machines powered by them to records and race success in 1905 and 1906. In the same period he had developed a three-cylinder version, more powerful than the twins. As the image shows, the engine fit neatly into the motorcycle frame. Engines with cylinders arranged radially but only in the upper half-circle were termed ''fan'' type, or semi-radials; by about 1910 other manufacturers were building e.g. five-cylinder fan engines, most notably R.E. ...

Sergant A
The Sergant A was a French 4-cylinder, air-cooled, upright inline piston engine with a maximum output of , designed to meet the needs of the very small and light single seat sports aircraft of the early 1920s. It was used by at least ten different types. Design and development In both the UK and France in the early 1920s there was a wish to make civilian flying more affordable, both in capital outlay and in running costs. This led to a need for low power engines. In Britain there were suitable engines like the Bristol Cherub but French designers were largely forced to import engines, either from the UK or Italy. The Sergant A was intended to provide a native product. It was on display at the November 1923 Paris Salon and struck ''Flights reporter as "extremely interesting" and car-engine like in its four cylinder inline arrangement, a little heavy but reliable. It was unusual in its high maximum crankshaft speed of 3,200 rpm and the availability of a choice of reduction ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Indian Chief (motorcycle)
The Indian Chief is a motorcycle that was built by the Hendee Manufacturing Company and the subsequent Indian Company from 1922 to the end of the company's production in 1953, and again from 1999 to present.The Chief was Indian's "big twin", a larger, more powerful motorcycle than the more agile Scout used in competition and sport riding. When Indian resumed civilian production after World War II, they revived only the Chief line. Production of Indian motorcycles ended with the last Chief made in 1953, then resumed again in 1999. Origin The Chief was introduced for 1922 to replace the Powerplus, although the Powerplus was continued under the "Standard" name until 1923. Designed by Charles B. Franklin, the Chief had design features similar to Franklin's earlier Scout, including the gearbox bolted to the engine casings and primary drive by gear train. The Chief had a bore of and a stroke of , giving a displacement of 61 cubic inches, as the Powerplus/Standard had. Unlike the ...

Waalhaven
Waalhaven Airport in 1932, with the Graf Zeppelin in the background. The Waalhaven is a harbour in Rotterdam, the Netherlands. It used to be home to an airport, Vliegveld Waalhaven (Waalhaven Airport). It was the second civilian airport in the Netherlands and was opened in 1920. Part of it was also in use by the Dutch military's 3rd JaVA Fokker G.I The Fokker G.I was a Dutch twin-engined heavy fighter aircraft comparable in size and role to the German Messerschmitt Bf 110. Although in production prior to World War II, its combat introduction came at a time the Netherlands were overrun by t ... squadron in 1940. Amongst others, the N.V. Koolhoven aircraft factory was located at this airport. The factory and airport were destroyed in 1940 by the Dutch army so it could not get into the hands of the Germans. After the Second World War, the city was in a prospect of finding an airport, but the existing airfield at Waalhaven was written off the list, because the damage that was ca ...

Wing Root
The wing root is the part of the wing on a fixed-wing aircraft or winged-spaceship that is closest to the fuselage,Peppler, I.L.: ''From The Ground Up'', page 9. Aviation Publishers Co. Limited, Ottawa Ontario, Twenty Seventh Revised Edition, 1996. and is the junction of the wing with the fuselage (not with a nacelle or any other body). The term is also used for the junction of the wing with the opposite wing, ie on the fuselage centerline, as with the upper wing of a biplane. The opposite end of a wing from the wing root is the wing tip. The aerodynamic properties of the overall aircraft can be greatly impacted by the shaping and other design choices of the wing root. During both normal flight and landings, the wing root of an aircraft would be typically subjected to the highest bending forces through the aircraft. As a means of reducing interference drag between the wing and the fuselage, the use of fairings (often referred to as "wing fillets") became commonplace during the fi ...

Aircraft Fairing
An aircraft fairing is a structure whose primary function is to produce a smooth outline and reduce drag.Crane, Dale: ''Dictionary of Aeronautical Terms, Third Edition'', page 206. Aviation Supplies & Academics Inc, Newcastle Washington, 1997. These structures are covers for gaps and spaces between parts of an aircraft to reduce form drag and interference drag, and to improve appearance.Bingelis, Tony: ''The Sportplane Builder'', pages 261-265. Experimental Aircraft Association Aviation Foundation, 1979. Types On aircraft, fairings are commonly found on: ; Belly fairing : Also called a "ventral fairing", it is located on the underside of the fuselage between the main wings. It can also cover additional cargo storage or fuel tanks. ; Cockpit fairing : Also called a "cockpit pod", it protects the crew on ultralight trikes. Commonly made from fiberglass, it may also incorporate a windshield.Cliche, Andre: ''Ultralight Aircraft Shopper's Guide'' 8th Edition, page C-17. Cybair ...

Conventional Undercarriage
Conventional landing gear, or tailwheel-type landing gear, is an aircraft undercarriage consisting of two main wheels forward of the center of gravity and a small wheel or skid to support the tail.Crane, Dale: ''Dictionary of Aeronautical Terms, third edition'', page 133. Aviation Supplies & Academics, 1997. From the Ground Up, 27th edition, page 11 The term taildragger is also used, although some argue it should apply only to those aircraft with a tailskid rather than a wheel. The term "conventional" persists for historical reasons, but all modern jet aircraft and most modern propeller aircraft use tricycle gear. History In early aircraft, a tailskid made of metal or wood was used to support the tail on the ground. In most modern aircraft with conventional landing gear, a small articulated wheel assembly is attached to the rearmost part of the airframe in place of the skid. This wheel may be steered by the pilot through a connection to the rudder pedals, allowing the rudder ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rudder
A rudder is a primary control surface used to steer a ship, boat, submarine, hovercraft, aircraft, or other vehicle that moves through a fluid medium (generally aircraft, air or watercraft, water). On an aircraft the rudder is used primarily to counter adverse yaw and p-factor and is not the primary control used to turn the airplane. A rudder operates by redirecting the fluid past the hull (watercraft), hull or fuselage, thus imparting a turning or yaw (rotation), yawing motion to the craft. In basic form, a rudder is a flat plane or sheet of material attached with hinges to the craft's stern, tail, or after end. Often rudders are shaped so as to minimize Drag (physics), hydrodynamic or aerodynamic drag. On simple watercraft, a tiller—essentially, a stick or pole acting as a lever arm—may be attached to the top of the rudder to allow it to be turned by a helmsman. In larger vessels, cables, pushrods, or hydraulics may be used to link rudders to steering wheels. In typical air ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
