Carmier T.10
The Charmier-Dupuy 10 was a French parasol-winged single seat light aircraft designed for low-cost flying. The sole example was first flown in 1924. Over a long career, it was fitted with three different engines and remained on the French register until after World War II. Design In the early 1920s there was considerable interest in both France and the UK in small single seat aircraft, designed to be cheap to buy and run and thus increase the civil light aircraft market. In France these were often referred to as avionettes; the Carmier avionette, which later was later named the Carmier-Depuy 10 or Carmier T.10 was one example at the high powered end of the range. Charles Carmier was helped in its design by Dupuy and in its construction by an experienced pilot, Chalambel. The Carmier was a parasol monoplane, with a two-part rectangular plan wing braced to the lower fuselage by pairs of parallel struts out to the spruce wing spars at about 40% span. They were thick in section ... [...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. Another WikiProject that has drawn attention is WikiProject Women Scientists, which was profiled by '' Smithsonian'' for its efforts to improve coverage of women scientists which the profile noted had "helped increase the number of female scientists on Wikipedia from around 1,600 to over 5,000".

Aircraft Fabric Covering
Aircraft fabric covering is a term used for both the material used and the process of covering aircraft open structures. It is also used for reinforcing closed plywood structures. The de Havilland Mosquito is an example of this technique, as are the pioneering all-wood monocoque fuselages of certain World War I German aircraft like the LFG Roland C.II in its wrapped ''Wickelrumpf'' plywood strip and fabric covering. Early aircraft used organic materials such as cotton and cellulose nitrate dope; modern fabric-covered designs usually use synthetic materials such as Dacron and butyrate dope for adhesive. Modern methods are often used in the restoration of older types that were originally covered using traditional methods. Purpose/requirements The purposes of the fabric covering of an aircraft are: * To provide a light airproof skin for lifting and control surfaces. * To provide structural strength to otherwise weak structures. * To cover other non-lifting parts of an airc ...

Flat-four Engine
A flat-four engine, also known as a horizontally opposed-four engine, is a four-cylinder piston engine with two banks of cylinders lying on opposite sides of a common crankshaft. The most common type of flat-four engine is the boxer-four engine, each pair of opposed pistons moves inwards and outwards at the same time. A boxer-four engine has perfect primary and secondary balance, however, the two cylinder heads means the design is more expensive to produce than an inline-four engine. Boxer-four engines have been used in cars since 1897, especially by Volkswagen and Subaru. They have also occasionally been used in motorcycles and frequently in aircraft. Cessna and Piper use flat four engines from Lycoming and Continental in the most common civil aircraft in the world - the Cessna 172, and Piper Cherokee, while many ultralight and LSA planes use versions of the Rotax 912. Design Most flat-four engines are designed so that each pair of opposing pistons moves inwards and o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ava 4A
The Ava 4A was a low power flat-four (boxer engine) developed for very light aircraft in France in the 1930s. It was used by several prototypes and at least one production series. Design and development Marcel Violet was a French racing driver who designed his own two-cylinder, two-stroke engines. He also designed a two stroke horizontally opposed flat-four, which was built under licence at ''L'agence general moteurs "Ava"'' by Jean Aubry of the ''Société J. Thibault, G Aubry et Cie'', alloy metal specialists, as the Ava 4A. It only produced and was intended to power small, low cost, single seat aircraft, replacing the aging Anzanis and completing with the French Mengin Type B and the older United Kingdom, British Bristol Cherub engines. The Ava 4A was on display at the November 1936 Paris Salon. It powered several prototypes and also the forty-six examples of the series production variant of the Farman Moustique, the F.451.

Pierre Levasseur (aircraft Builder)
Pierre Georges Albert Levasseur (July 16, 1890 in Paris – August 2, 1941 in Paris) was a French aircraft and component maker. He set up his company ''Société Pierre Levasseur Aéronautique'', always referred to simply as Levasseur in Paris in 1910, beginning by making propellers. In 1913 he began building aircraft designed by others. He then began to design his own, the majority of which were single-engine biplanes for French Naval Aviation. He also ran a flying school, where the chief pilot of his school was François Denhaut (1877–1952), notable for designing the first flying boat. Georges Abrial (1898 – 1970), an early French aerodynamicist, also worked with Levasseur to produce the Levasseur-Abrial A-1. Sociéte Pierre Levasseur Aéronautique Models created included: * Levasseur-Abrial A-1, 1922 glider * Levasseur PL.2, naval biplane torpedo bomber * Levasseur PL.4, carrier-based reconnaissance aircraft * Levasseur PL.5, carrier-based fighter * Levasseur PL.6, 1926 tw ...

Paris-Orly Airport
Paris Orly Airport (french: Aéroport de Paris-Orly), commonly referred to as Orly , is one of two international airports serving the French capital, Paris, the other one being Charles de Gaulle Airport (CDG). It is located partially in Orly and partially in Villeneuve-le-Roi, south of Paris, France. It serves as a secondary hub for domestic and overseas territories flights of Air France and as the homebase for Transavia France. Flights operate to destinations in Europe, the Middle East, Africa, the Caribbean and North America. Before the opening of Charles de Gaulle Airport in 1974, Orly was the main airport of Paris. Even with the shift of most international traffic to Charles de Gaulle Airport, Orly remains the busiest French airport for domestic traffic and the second busiest French airport overall in passenger traffic, with 33,120,685 passengers in 2018. The airport is operated by Groupe ADP under the brand Paris Aéroport. Since February 2018, the CEO of the airport has ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Shock Absorbers
A shock absorber or damper is a mechanical or hydraulic device designed to absorb and damp shock impulses. It does this by converting the kinetic energy of the shock into another form of energy (typically heat) which is then dissipated. Most shock absorbers are a form of dashpot (a damper which resists motion via viscous friction). Description Pneumatic and hydraulic shock absorbers are used in conjunction with cushions and springs. An automobile shock absorber contains spring-loaded check valves and orifices to control the flow of oil through an internal piston (see below). One design consideration, when designing or choosing a shock absorber, is where that energy will go. In most shock absorbers, energy is converted to heat inside the viscous fluid. In hydraulic cylinders, the hydraulic fluid heats up, while in air cylinders, the hot air is usually exhausted to the atmosphere. In other types of shock absorbers, such as electromagnetic types, the dissipated energy can be s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Landing Gear
Landing gear is the undercarriage of an aircraft or spacecraft that is used for takeoff or landing. For aircraft it is generally needed for both. It was also formerly called ''alighting gear'' by some manufacturers, such as the Glenn L. Martin Company. For aircraft, Stinton makes the terminology distinction ''undercarriage (British) = landing gear (US)''. For aircraft, the landing gear supports the craft when it is not flying, allowing it to take off, land, and taxi without damage. Wheeled landing gear is the most common, with skis or floats needed to operate from snow/ice/water and skids for vertical operation on land. Faster aircraft have retractable undercarriages, which fold away during flight to reduce drag. Some unusual landing gear have been evaluated experimentally. These include: no landing gear (to save weight), made possible by operating from a catapult cradle and flexible landing deck: air cushion (to enable operation over a wide range of ground obstacles and wat ...

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] |
Fin (aeronautics)
An aircraft stabilizer is an aerodynamic surface, typically including one or more movable control surfaces, that provides longitudinal (pitch) and/or directional (yaw) stability and control. A stabilizer can feature a fixed or adjustable structure on which any movable control surfaces are hinged, or it can itself be a fully movable surface such as a stabilator. Depending on the context, "stabilizer" may sometimes describe only the front part of the overall surface. In the conventional aircraft configuration, separate vertical (fin) and horizontal (tailplane) stabilizers form an empennage positioned at the tail of the aircraft. Other arrangements of the empennage, such as the V-tail configuration, feature stabilizers which contribute to a combination of longitudinal and directional stabilization and control. Longitudinal stability and control may be obtained with other wing configurations, including canard, tandem wing and tailless aircraft. Some types of aircraft are stabiliz ...

Stabilator
A stabilator is a fully movable aircraft horizontal stabilizer. It serves the usual functions of longitudinal stability, control and stick force requirements otherwise performed by the separate parts of a conventional horizontal stabilizer and elevator. Apart from reduced drag, particularly at high Mach numbers, it is a useful device for changing the aircraft balance within wide limits, and for reducing stick forces. Stabilator is a portmanteau of ''stabilizer'' and ''elevator''. It is also known as an all-moving tailplane, all-movable tail(plane), all-moving stabilizer, all-flying tail(plane), all-flying horizontal tail, full-flying stabilizer, and slab tailplane. General aviation Because it involves a moving balanced surface, a stabilator can allow the pilot to generate a given pitching moment with a lower control force. Due to the high forces involved in tail balancing loads, stabilators are designed to pivot about their aerodynamic center (near the tail's mean quarter-chord ...

Trailing Edge
The trailing edge of an aerodynamic surface such as a wing is its rear edge, where the airflow separated by the leading edge meets.Crane, Dale: ''Dictionary of Aeronautical Terms, third edition'', page 521. Aviation Supplies & Academics, 1997. Essential flight control surfaces are attached here to control the direction of the departing air flow, and exert a controlling force on the aircraft. Such control surfaces include ailerons on the wings for roll control, elevators on the tailplane controlling pitch, and the rudder on the fin controlling yaw. Elevators and ailerons may be combined as elevons on tailless aircraft. The shape of the trailing edge is of prime importance in the aerodynamic function of any aerodynamic surface. George Batchelor has written about: :“ ... the remarkable controlling influence exerted by the sharp trailing edge of an aerofoil on the circulation.”Batchelor, G. K. (1967), ''An Introduction to Fluid Dynamics'', p.438, Cambridge University Press. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
