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 Aerodynamics, 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 (aircraft), glider * Levasseur PL.1, 1922, three seat tourer * Levasseur PL.2, naval biplane torpedo bomber * Levasseur PL.4, carrier-based reconnaissance ai ...

Orteig Prize
The Orteig Prize was a reward of $25,000 offered in 1919 by New York City hotel owner Raymond Orteig to the first Allies of World War I, Allied aviator, or aviators, to fly non-stop from New York City to Paris or vice versa.Bak. Pages 28 and 29. Several famous aviators made unsuccessful attempts at the New York–Paris flight before a relatively unknown American, Charles Lindbergh, won the prize in 1927 with his aircraft the ''Spirit of St. Louis''. A number of people died while competing to win the prize. Six people perished in three separate crashes, and another three were injured in a fourth crash. The Orteig Prize spurred considerable investment in aviation—sometimes far exceeding the value of the prize itself—and also advanced public interest in, and the development of, aviation technology. Background The Orteig Prize was a $25,000 reward () offered on May 22, 1919, by New York hotel owner Raymond Orteig to the first Allied aviator(s) to fly non-stop from New York City to ...

Seaplane
A seaplane is a powered fixed-wing aircraft capable of takeoff, taking off and water landing, landing (alighting) on water.Gunston, "The Cambridge Aerospace Dictionary", 2009. Seaplanes are usually divided into two categories based on their technological characteristics: floatplanes and flying boats; the latter are generally far larger and can carry far more. Seaplanes that can also take off and land on airfields are in a subclass called amphibious aircraft, or amphibians. Seaplanes were sometimes called ''hydroplanes'', but currently this term applies instead to Hydroplane (boat), motor-powered watercraft that use the technique of Planing (boat), hydrodynamic lift to skim the surface of water when running at speed. The use of seaplanes gradually tapered off after World War II, partially because of the investments in airports during the war but mainly because landplanes were less constrained by weather conditions that could result in sea states being too high to operate seaplanes ...

New York City
New York, often called New York City (NYC), is the most populous city in the United States, located at the southern tip of New York State on one of the world's largest natural harbors. The city comprises five boroughs, each coextensive with a respective county. The city is the geographical and demographic center of both the Northeast megalopolis and the New York metropolitan area, the largest metropolitan area in the United States by both population and urban area. New York is a global center of finance and commerce, culture, technology, entertainment and media, academics, and scientific output, the arts and fashion, and, as home to the headquarters of the United Nations, international diplomacy. With an estimated population in 2024 of 8,478,072 distributed over , the city is the most densely populated major city in the United States. New York City has more than double the population of Los Angeles, the nation's second-most populous city. [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Transatlantic Flight
A transatlantic flight is the flight of an aircraft across the Atlantic Ocean from Europe, Africa, South Asia, or the Middle East to North America, South America, or ''vice versa''. Such flights have been made by fixed-wing aircraft, airships, balloon (aircraft), balloons and other aircraft. Early aircraft engines had neither the reliability nor the power to lift the required fuel to make a transatlantic flight. There were difficulties navigating over the featureless expanse of water for thousands of miles, and the weather, especially in the North Atlantic Ocean, North Atlantic, is unpredictable. Since the middle of the 20th century, however, transatlantic flight has become routine, for commerce, commercial, military, diplomacy, diplomatic, and other purposes. History The idea of transatlantic flight came about with the advent of the hot air balloon. The balloons of the period were inflated with coal gas, a moderate lifting medium compared to hydrogen or helium, but with enough l ...

The White Bird
''L'Oiseau Blanc'' (; English: ''The White Bird'') was a French Levasseur PL.8 biplane that disappeared in 1927 during an attempt to make the first non-stop transatlantic flight between Paris and New York City to compete for the Orteig Prize. French World War I aviation heroes Charles Nungesser (third highest French Flying ace, ace with 43 air combat victories during World War I) and François Coli took off from Paris on 8 May 1927 and were last seen over Ireland. Less than two weeks later, Charles Lindbergh flew New York–Paris in the ''Spirit of St. Louis'' and claimed the prize. The disappearance of ''L'Oiseau Blanc'' is considered one of the great mysteries in the history of aviation. Many rumors circulated about the fate of the aircraft and crew, with mainstream opinion at the time being that it was probably lost in a squall over the Atlantic. Investigations starting in the 1980s suggest that it probably reached Newfoundland and may have crashed in Maine. The disappeara ...

Fighter Aircraft
Fighter aircraft (early on also ''pursuit aircraft'') are military aircraft designed primarily for air-to-air combat. In military conflict, the role of fighter aircraft is to establish air supremacy, air superiority of the battlespace. Domination of the airspace above a battlefield permits bombers and attack aircraft to engage in tactical bombing, tactical and strategic bombing of enemy targets, and helps prevent the enemy from doing the same. 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 aircraft, ground attack and some types, such as fighter-b ...

Biplane
A biplane is a fixed-wing aircraft with two main wings stacked one above the other. The first powered, controlled aeroplane to fly, the Wright Flyer, used a biplane wing arrangement, as did many aircraft in the early years of aviation. While a biplane wing structure has a structural advantage over a monoplane, it produces more drag than a monoplane wing. Improved structural techniques, better materials and higher speeds made the biplane configuration obsolete for most purposes by the late 1930s. Biplanes offer several advantages over conventional cantilever monoplane designs: they permit lighter wing structures, low wing loading and smaller span for a given wing area. However, interference between the airflow over each wing increases drag substantially, and biplanes generally need extensive bracing, which causes additional drag. Biplanes are distinguished from tandem wing arrangements, where the wings are placed forward and aft, instead of above and below. The term is als ...
