Dewoitine
Constructions Aéronautiques Émile Dewoitine was a French aircraft manufacturer established in Toulouse by Émile Dewoitine in October 1920. The company's initial products were a range of metal parasol-wing fighters, which were largely ignored by the French Air Force but purchased in large quantities abroad and licence-built in Italy, Switzerland, and Czechoslovakia. The company was liquidated in January 1927, with the only remaining active programme (the D.27) being transferred to EKW in Switzerland. The company was then re-established in Paris in March of the following year as Société Aéronautique Française (Avions Dewoitine) or SAF. After briefly continuing D.27 production, the reconstituted firm produced a range of fighters, the D.500 family, that became a mainstay of the French Air Force during the 1930s. It also developed important civilian airliners, such as the D.333 and its derivative the D.338, designed for pioneering routes to French Indochina (now Vietnam), a ...

Collier Trophy
The Robert J. Collier Trophy is awarded annually "for the greatest achievement in aeronautics or astronautics in America, with respect to improving the performance, efficiency, and safety of air or space vehicles, the value of which has been thoroughly demonstrated by actual use during the preceding year." The Collier Trophy is administered by the National Aeronautic Association (NAA) the oldest national aviation organization in the United States. Founded in 1905, the NAA oversees America's oldest and most prestigious aviation and aerospace recognitions. The Collier Trophy is the most coveted of all. Robert J. Collier, publisher of '' Collier's Weekly'' magazine, was an air sports pioneer and president of the Aero Club of America. In 1910, he commissioned Baltimore sculptor Ernest Wise Keyser to make the ''Aero Club of America Trophy''. It was first awarded in 1911 to Glenn H. Curtiss for his successful development of the hydro-aeroplane. Collier presented his namesake ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fuel Efficiency
Fuel efficiency (or fuel economy) is a form of thermal efficiency, meaning the ratio of effort to result of a process that converts chemical energy, chemical potential energy contained in a carrier (fuel) into kinetic energy or Mechanical work, work. Overall fuel efficiency may vary per device, which in turn may vary per application, and this spectrum of variance is often illustrated as a continuous energy profile. Non-transportation applications, such as Industrial sector, industry, benefit from increased fuel efficiency, especially fossil fuel power plants or industries dealing with combustion, such as ammonia production during the Haber process. In the context of transport, fuel economy is the energy efficiency in transportation, energy efficiency of a particular vehicle, given as a ratio of distance traveled per unit of Motor fuel, fuel consumed. It is dependent on several factors including engine efficiency, transmission (mechanics), transmission design, and tire design. In ...

Aerodynamic Drag
In fluid dynamics, drag, sometimes referred to as fluid resistance, is a force acting opposite to the direction of motion of any object moving with respect to a surrounding fluid. This can exist between two fluid layers, two solid surfaces, or between a fluid and a solid surface. Drag forces tend to decrease fluid velocity relative to the solid object in the fluid's path. Unlike other resistive forces, drag force depends on velocity. Drag force is proportional to the relative velocity for low-speed flow and is proportional to the velocity squared for high-speed flow. This distinction between low and high-speed flow is measured by the Reynolds number. Drag is instantaneously related to vorticity dynamics through the Josephson-Anderson relation. Examples Examples of drag include: * Net force, Net Aerodynamic force, aerodynamic or Fluid dynamics, hydrodynamic force: Drag acting opposite to the direction of movement of a solid object such as cars, aircraft, and boat hulls. * Viscou ...

Airplane
An airplane (American English), or aeroplane (Commonwealth English), informally plane, is a fixed-wing aircraft that is propelled forward by thrust from a jet engine, Propeller (aircraft), propeller, or rocket engine. Airplanes come in a variety of sizes, shapes, and wing configurations. The broad spectrum of uses for airplanes includes recreation, air transportation, transportation of goods and people, military aviation, military, and Experimental aircraft, research. Worldwide, commercial aviation transports more than four billion passengers annually on airliners and transports more than 200 billion tonne-kilometersMeasured in RTKs—an RTK is one tonne of revenue freight carried one kilometer. of cargo annually, which is less than 1% of the world's cargo movement. Most airplanes are flown by a pilot on board the aircraft, but some are designed to be unmanned aerial vehicle, remotely or computer-controlled such as drones. The Wright brothers invented and flew the Wright Flyer ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Radial Engine
The radial engine is a reciprocating engine, reciprocating type internal combustion engine, internal combustion engine configuration in which the cylinder (engine), cylinders "radiate" outward from a central crankcase like the spokes of a wheel. It resembles a stylized Star polygon, star when viewed from the front, and is called a "star engine" in some other languages. The radial configuration was commonly used for aircraft engines before gas turbine engines became predominant. Engine operation Since the axes of the cylinders are coplanar, the connecting rods cannot all be directly attached to the crankshaft unless mechanically complex forked connecting rods are used, none of which have been successful. Instead, the pistons are connected to the crankshaft with a master-and-articulating-rod assembly. One piston, the uppermost one in the animation, has a master rod with a direct attachment to the crankshaft. The remaining pistons pin their connecting rods' attachments to rings ar ...

Streamliner
A streamliner is a vehicle incorporating streamlining in a shape providing reduced air resistance. The term is applied to high-speed railway trainsets of the 1930s to 1950s, and to their successor " bullet trains". Less commonly, the term is applied to fully faired upright and recumbent bicycles. As part of the Streamline Moderne trend, the term was applied to passenger cars, trucks, and other types of light-, medium-, or heavy-duty vehicles, but now vehicle streamlining is so prevalent that it is not an outstanding characteristic. In land speed racing, it is a term applied to the long, slender, custom built, high-speed vehicles with enclosed wheels. Trains Before World War II Europe * Germany, 1930: The first high-speed streamliner in Germany was the '' Schienenzeppelin'', an experimental propeller-driven single car, built in 1930. On 21 June 1931, the car set a speed record of on a run between Berlin and Hamburg. In 1932 the propeller was removed and a h ...

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. Cybai ...

Aerodynamic
Aerodynamics () is the study of the motion of atmosphere of Earth, air, particularly when affected by a solid object, such as an airplane wing. It involves topics covered in the field of fluid dynamics and its subfield of gas dynamics, and is an important domain of study in aeronautics. The term ''aerodynamics'' is often used synonymously with gas dynamics, the difference being that "gas dynamics" applies to the study of the motion of all gases, and is not limited to air. The formal study of aerodynamics began in the modern sense in the eighteenth century, although observations of fundamental concepts such as aerodynamic drag were recorded much earlier. Most of the early efforts in aerodynamics were directed toward achieving Aircraft#Heavier-than-air – aerodynes, heavier-than-air flight, which was first demonstrated by Otto Lilienthal in 1891. Since then, the use of aerodynamics through mathematical analysis, empirical approximations, wind tunnel experimentation, and computer si ...
