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 ...

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 also ...

Orteig Prize
The Orteig Prize was a reward offered to the first Allied aviator(s) 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 the relatively unknown American Charles Lindbergh won the prize in 1927 in his aircraft ''Spirit of St. Louis''. However, a number of people died who were competing to win the prize. Six men died in three separate crashes, and another three were injured in a fourth crash. The Prize occasioned considerable investment in aviation, sometimes many times the value of the prize itself, and advancing public interest and the level 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 Paris or vice versa. The offer was in the spirit of several similar aviation prize offers, and was made in a letter ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Aircraft Propeller Manufacturers
An aircraft is a vehicle that is able to fly by gaining support from the air. It counters the force of gravity by using either static lift or by using the dynamic lift of an airfoil, or in a few cases the downward thrust from jet engines. Common examples of aircraft include airplanes, helicopters, airships (including blimps), gliders, paramotors, and hot air balloons. The human activity that surrounds aircraft is called ''aviation''. The science of aviation, including designing and building aircraft, is called ''aeronautics.'' Crewed aircraft are flown by an onboard pilot, but unmanned aerial vehicles may be remotely controlled or self-controlled by onboard computers. Aircraft may be classified by different criteria, such as lift type, aircraft propulsion, usage and others. History Flying model craft and stories of manned flight go back many centuries; however, the first manned ascent — and safe descent — in modern times took place by larger hot-air ball ...

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 seaplan ...

Paris
Paris () is the capital and most populous city of France, with an estimated population of 2,165,423 residents in 2019 in an area of more than 105 km² (41 sq mi), making it the 30th most densely populated city in the world in 2020. Since the 17th century, Paris has been one of the world's major centres of finance, diplomacy, commerce, fashion, gastronomy, and science. For its leading role in the arts and sciences, as well as its very early system of street lighting, in the 19th century it became known as "the City of Light". Like London, prior to the Second World War, it was also sometimes called the capital of the world. The City of Paris is the centre of the Île-de-France region, or Paris Region, with an estimated population of 12,262,544 in 2019, or about 19% of the population of France, making the region France's primate city. The Paris Region had a GDP of €739 billion ($743 billion) in 2019, which is the highest in Europe. According to the Economist Intelli ...

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, Central America, or South America, or ''vice versa''. Such flights have been made by fixed-wing aircraft, airships, balloons and other aircraft. Early aircraft engines did not have 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, is unpredictable. Since the middle of the 20th century, however, transatlantic flight has become routine, for commercial, military, 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 lift to use the winds that would later be ...

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 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 successfully made the New York–Paris journey and claimed the prize in the ''Spirit of St. Louis''. 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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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] |
French Naval Aviation
French Naval Aviation (often abbreviated in French to: ''Aéronavale'' (contraction of Aéronautique navale), or ''Aviation navale'', or more simply ''l'Aéro'') is the naval air arm of the French Navy. The long-form official designation is ''Force maritime de l'aéronautique navale''. Born as a fusion of aircraft carrier squadrons and the naval patrol air force, the ''Aéronavale'' was created in 1912. The force is under the command of a flag officer officially titled Admiral of Naval Aviation (ALAVIA) with his headquarters at Toulon naval base. It has a strength of around 6,800 military and civilian personnel. It operates from four airbases in Metropolitan France and several detachments in foreign countries or French overseas territories. Carrier-borne pilots of the French Navy do their initial training at Salon-de-Provence Air Base after which they undergo their carrier qualification with the US Navy.
