Air Racer
Air racing is a type of motorsport that involves airplanes or other types of aircraft that compete over a fixed course, with the winner either returning the shortest time, the one to complete it with the most points, or to come closest to a previously estimated time. History The first 'heavier-than-air' air race was held on 23 May 1909 - the Prix de Lagatinerie, at the Port-Aviation airport south of Paris, France. Four pilots entered the race, two started, but nobody completed the full race distance; though this was not unexpected, as the rules specified that whoever travelled furthest would be the winner if no-one completed the race. Léon Delagrange, who covered slightly more than half of the ten laps was declared the winner. Some other minor events were held before the ''Grande Semaine d'Aviation de la Champagne'' in 22–29 August 1909 at Reims, France. This was the first major international flying event, drawing the most important aircraft makers and pilots of the era, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

North is one of the four compass points or cardinal directions. It is the opposite of south and is perpendicular to east and west. ''North'' is a noun, adjective, or adverb indicating Direction (geometry), direction or geography. Etymology The word ''north'' is etymology, related to the Old High German ''nord'', both descending from the Proto-Indo-European language, Proto-Indo-European unit *''ner-'', meaning "left; below" as north is to left when facing the rising sun. Similarly, the other cardinal directions are also related to the sun's position. The Latin word ''borealis'' comes from the Ancient Greek, Greek ''Anemoi#Boreas, boreas'' "north wind, north", which, according to Ovid, was personified as the wind-god Anemoi#Boreas, Boreas, the father of Calais and Zetes. ''Septentrionalis'' is from ''septentriones'', "the seven plow oxen", a name of ''Ursa Major''. The Greek ἀρκτικός (''arktikós'') is named for the same constellation, and is the source of the English ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
William Randolph Hearst
William Randolph Hearst Sr. (; April 29, 1863 – August 14, 1951) was an American businessman, newspaper publisher, and politician known for developing the nation's largest newspaper chain and media company, Hearst Communications. His flamboyant methods of yellow journalism influenced the nation's popular media by emphasizing sensationalism and human interest stories. Hearst entered the publishing business in 1887 with Mitchell Trubitt after being given control of ''The San Francisco Examiner'' by his wealthy father, Senator George Hearst. After moving to New York City, Hearst acquired the '' New York Journal'' and fought a bitter circulation war with Joseph Pulitzer's '' New York World''. Hearst sold papers by printing giant headlines over lurid stories featuring crime, corruption, sex, and innuendos. Hearst acquired more newspapers and created a chain that numbered nearly 30 papers in major American cities at its peak. He later expanded to magazines, creating the largest ne ...

Fighter Aircraft
Fighter aircraft are fixed-wing military aircraft designed primarily for air-to-air combat. In military conflict, the role of fighter aircraft is to establish air superiority of the battlespace. Domination of the airspace above a battlefield permits bombers and attack aircraft to engage in tactical and strategic bombing of enemy targets. The key performance features of a fighter include not only its firepower but also its high speed and maneuverability relative to the target aircraft. The success or failure of a combatant's efforts to gain air superiority hinges on several factors including the skill of its pilots, the tactical soundness of its doctrine for deploying its fighters, and the numbers and performance of those fighters. Many modern fighter aircraft also have secondary capabilities such as ground attack and some types, such as fighter-bombers, are designed from the outset for dual roles. Other fighter designs are highly specialized while still filling the ma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aero Engine
An aircraft engine, often referred to as an aero engine, is the power component of an aircraft propulsion system. Most aircraft engines are either piston engines or gas turbines, although a few have been rocket powered and in recent years many small UAVs have used electric motors. Manufacturing industry In commercial aviation the major Western manufacturers of turbofan engines are Pratt & Whitney (a subsidiary of Raytheon Technologies), General Electric, Rolls-Royce, and CFM International (a joint venture of Safran Aircraft Engines and General Electric). Russian manufacturers include the United Engine Corporation, Aviadvigatel and Klimov. Aeroengine Corporation of China was formed in 2016 with the merger of several smaller companies. The largest manufacturer of turboprop engines for general aviation is Pratt & Whitney. General Electric announced in 2015 entrance into the market.

Aerodynamics
Aerodynamics, from grc, ἀήρ ''aero'' (air) + grc, δυναμική (dynamics), is the study of the motion of 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. 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 simu ...

Aircraft Design Process
The aircraft design process is a loosely defined method used to balance many competing and demanding requirements to produce an aircraft that is strong, lightweight, economical and can carry an adequate payload while being sufficiently reliable to safely fly for the design life of the aircraft. Similar to, but more exacting than, the usual engineering design process, the technique is highly iterative, involving high level configuration tradeoffs, a mixture of analysis and testing and the detailed examination of the adequacy of every part of the structure. For some types of aircraft, the design process is regulated by civil airworthiness authorities. This article deals with powered aircraft such as airplanes and helicopter designs. Design constraints Purpose The design process starts with the aircraft's intended purpose. Commercial airliners are designed for carrying a passenger or cargo payload, long range and greater fuel efficiency where as fighter jets are designed to perform ...

Schneider Trophy
The Coupe d'Aviation Maritime Jacques Schneider, also known as the Schneider Trophy, Schneider Prize or (incorrectly) the Schneider Cup is a trophy that was awarded annually (and later, biennially) to the winner of a race for seaplanes and flying boats. The Schneider Trophy is now held at the Science Museum, South Kensington, London. Announced in 1912 by Jacques Schneider, a French financier, balloonist and aircraft enthusiast, the competition offered a prize of approximately £1,000. The race was held twelve times between 1913 and 1931. It was intended to encourage technical advances in civil aviation but became a contest for pure speed with laps over a (usually) triangular course, initially and later extended to . The contests were staged as time trials, with aircraft setting off individually at set intervals, usually 15 minutes apart. The contests were very popular and some attracted crowds of over 200,000 spectators. The race was significant in advancing aeroplane design, pa ...

Aerial Derby
The Aerial Derby was an air race in the United Kingdom sponsored by the '' Daily Mail'' in which the competitors flew a circuit around London. It was first held in 1912, with subsequent races in 1913 and 1914. Suspended during the First World War, the event was revived in 1919 with a "Victory Aerial Derby". Further races were held in 1920, 1921,1922 and 1923. Although a race was scheduled for 1924 there were insufficient entries, and the event was cancelled and not held again. 1912 The first race, held on Saturday 8 June consisted of a single circuit of an course, starting and finishing at Hendon Aerodrome with control points at Kempton Park, Esher, Purley and Purfleet. At these contestants had to fly low enough for the judges to see the race number of their aircraft. The first prize was £250 and a gold cup. The first competition was the subject of enormous public interest, with around 45,000 people paying to view the start and finish at Hendon and enormous crowds gather ...

Aviation
Aviation includes the activities surrounding mechanical flight and the aircraft industry. ''Aircraft'' includes fixed-wing and rotary-wing types, morphable wings, wing-less lifting bodies, as well as lighter-than-air craft such as hot air balloons and airships. Aviation began in the 18th century with the development of the hot air balloon, an apparatus capable of atmospheric displacement through buoyancy. Some of the most significant advancements in aviation technology came with the controlled gliding flying of Otto Lilienthal in 1896; then a large step in significance came with the construction of the first powered airplane by the Wright brothers in the early 1900s. Since that time, aviation has been technologically revolutionized by the introduction of the jet which permitted a major form of transport throughout the world. Etymology The word ''aviation'' was coined by the French writer and former naval officer Gabriel La Landelle in 1863. He derived the term from the v ...
