Maiden Flight
The maiden flight, also known as first flight, of an aircraft is the first occasion on which it leaves the ground under its own power. The same term is also used for the first launch of rockets. The maiden flight of a new aircraft type is always a historic occasion for the type and can be quite emotional for those involved. In the early days of aviation it could be dangerous, because the exact handling characteristics of the aircraft were generally unknown. The maiden flight of a new type is almost invariably flown by a highly experienced test pilot. Maiden flights are usually accompanied by a chase plane, to verify items like altitude, airspeed, and general airworthiness. A maiden flight is only one stage in the development of an aircraft type. Unless the type is a pure research aircraft (such as the X-15), the aircraft must be tested extensively to ensure that it delivers the desired performance with an acceptable margin of safety. In the case of civilian aircraft, a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aircraft
An aircraft is a vehicle that is able to flight, fly by gaining support from the Atmosphere of Earth, air. It counters the force of gravity by using either Buoyancy, static lift or by using the Lift (force), dynamic lift of an airfoil, or in a few cases the Powered lift, downward thrust from jet engines. Common examples of aircraft include airplanes, helicopters, airships (including blimps), Glider (aircraft), gliders, Powered paragliding, 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.'' Aircrew, Crewed aircraft are flown by an onboard Aircraft pilot, 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, Powered aircraft#Methods of propulsion, aircraft propulsion, usage and others. History Flying model craft an ...

Leutershausen
Leutershausen is a municipality in the district of Ansbach, in Bavaria, Germany. It is situated on the river Altmühl, 12 km west of Ansbach. History Leutershausen was probably founded by Frankish settlers around 800. For the first time it is referred to in a privilege of Emperor Otto III as "Liuthereshusunin" in 1000. On the 19th of April, 1945, the village was almost completely destroyed by Allied fighter-bombers (Veeh, 'Kriegsfurie', pp. 452, 457-461; Woller, 'Gesellschaft und Politik in der amerikanischen Besatzungszone: Die Region Ansbach und Fürth', pp. 55-56) Sport Leutershausen has a sportsclub, called TV 1862 Leutershausen. As said in the name it was founded in 1862 and has since organised sport events at the local stadium and provides training in seven different disciplines, the biggest being football and athletics. Furthermore, there are table tennis, tennis, gymnastics, triathlon and ball game departments. In June 2012 there was a big celebration weekend due t ...

Glenn Curtiss
Glenn Hammond Curtiss (May 21, 1878 – July 23, 1930) was an American aviation and motorcycling pioneer, and a founder of the U.S. aircraft industry. He began his career as a bicycle racer and builder before moving on to motorcycles. As early as 1904, he began to manufacture engines for airships. In 1908, Curtiss joined the Aerial Experiment Association, a pioneering research group, founded by Alexander Graham Bell at Beinn Bhreagh, Nova Scotia, to build flying machines. Curtiss won a race at the world's first international air meet in France and made the first long-distance flight in the U.S. His contributions in designing and building aircraft led to the formation of the Curtiss Aeroplane and Motor Company, which later merged into the Curtiss-Wright Corporation. His company built aircraft for the U.S. Army and Navy, and, during the years leading up to World War I, his experiments with seaplanes led to advances in naval aviation. Curtiss civil and military aircraft were some ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
14-bis
The ''14-bis'' (french: Quatorze-bis), (), also known as ("bird of prey" in French), was a pioneer era, canard-style biplane designed and built by Brazilian aviation pioneer Alberto Santos-Dumont. In 1906, near Paris, the ''14-bis'' made a manned powered flight that was the first to be publicly witnessed by a crowd. Background In June 1905, French aviator Gabriel Voisin had flown a glider towed by a fast boat on the river Seine, making a flight of over . The glider's wing and tail were made up of Hargrave cells, a box kite-like structure that provided a degree of inherent stability. This established the Hargrave cell as a configuration useful not only for kites but also for heavier-than-air aircraft. Santos-Dumont was living in Paris at the time, and was one of the most active "aeronauts" in Europe, having developed a series of non-rigid airships that displayed unparalleled agility, speed, endurance, and ease of control. Santos-Dumont met Voisin at the end of 1905, and commi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Alberto Santos-Dumont
Alberto Santos-Dumont ( Palmira, 20 July 1873 — Guarujá, 23 July 1932) was a Brazilian aeronaut, sportsman, inventor, and one of the few people to have contributed significantly to the early development of both lighter-than-air and heavier-than-air aircraft. The heir of a wealthy family of coffee producers, he dedicated himself to aeronautical study and experimentation in Paris, where he spent most of his adult life. He designed, built, and flew the first powered airships and won the Deutsch Prize in 1901, when he flew around the Eiffel Tower in his airship No. 6, becoming one of the most famous people in the world in the early 20th century. Santos-Dumont then progressed to powered heavier-than-air machines and on 23 October 1906 flew about 60 metres at a height of two to three metres with the fixed-wing 14-bis (also dubbed the ''Oiseau de Proie''—"bird of prey") at the Bagatelle Gamefield in Paris, taking off unassisted by an external launch system.

Monoplane
A monoplane is a fixed-wing aircraft configuration with a single mainplane, in contrast to a biplane or other types of multiplanes, which have multiple planes. A monoplane has inherently the highest efficiency and lowest drag of any wing configuration and is the simplest to build. However, during the early years of flight, these advantages were offset by its greater weight and lower manoeuvrability, making it relatively rare until the 1930s. Since then, the monoplane has been the most common form for a fixed-wing aircraft. Characteristics Support and weight The inherent efficiency of the monoplane is best achieved in the cantilever wing, which carries all structural forces internally. However, to fly at practical speeds the wing must be made thin, which requires a heavy structure to make it strong and stiff enough. External bracing can be used to improve structural efficiency, reducing weight and cost. For a wing of a given size, the weight reduction allows it to fly slower ...

Romanians
The Romanians ( ro, români, ; dated exonym '' Vlachs'') are a Romance-speaking ethnic group. Sharing a common Romanian culture and ancestry, and speaking the Romanian language, they live primarily in Romania and Moldova. The 2011 Romanian census found that just under 89% of Romania's citizens identified themselves as ethnic Romanians. In one interpretation of the 1989 census results in Moldova, the majority of Moldovans were counted as ethnic Romanians.''Ethnic Groups Worldwide: A Ready Reference Handbook By'' David Levinson, Published 1998 – Greenwood Publishing Group.At the time of the 1989 census, Moldova's total population was 4,335,400. The largest nationality in the republic, ethnic Romanians, numbered 2,795,000 persons, accounting for 64.5 percent of the population.

Traian Vuia
Traian Vuia or Trajan Vuia (; August 17, 1872 – September 3, 1950) was a Romanian inventor and aviation pioneer who designed, built and tested the first tractor monoplane. He was the first to demonstrate that a flying machine could rise into the air by running on wheels on an ordinary road. He is credited with a powered hop of made on March 18, 1906, and he later claimed a powered hop of . Though unsuccessful in sustained flight, Vuia's invention influenced Louis Blériot in designing monoplanes. Later, Vuia also designed helicopters. A French citizen from 1918, Vuia led the Romanians (especially Transylvanians) of France in the Resistance during World War II. He returned to Romania just before his death in 1950. Education and early career Vuia was born from Romanian parents – Simion Popescu, a priest, and his second wife, Ana Vuia – living in Surducul-Mic and/or Bujor, where he attended the local primary school, and Făget, a village in the Banat region, Austro-Hungari ...

Kitty Hawk, North Carolina
Kitty Hawk is a town in Dare County, North Carolina, United States, and is a part of what is known as North Carolina's Outer Banks. The population was 3,708 at the 2020 Census. It was established in the early 18th century as Chickahawk. History The name Kitty Hawk is derived from the native Algonquin Amerindian language word Chickahawk, meaning "a place to hunt geese". Kitty Hawk became world-famous after the Wright brothers made the first controlled powered airplane flights at Kill Devil Hills, four miles (6 km) south of the town, on December 17, 1903. After the four flights in their ''Wright Flyer'', the brothers walked back to Kitty Hawk. Here, they sent a telegram from the Weather Bureau office to their father informing him of their success. Kitty Hawk is usually credited as the site of the powered flights because it was the nearest named settlement at the time of the flight; the modern town of Kill Devil Hills did not exist until 50 years after the flights.

Wright Flyer
The ''Wright Flyer'' (also known as the ''Kitty Hawk'', ''Flyer'' I or the 1903 ''Flyer'') made the first sustained flight by a manned heavier-than-air powered and controlled aircraft—an airplane—on December 17, 1903. Invented and flown by Wright brothers, Orville and Wilbur Wright, it marked the beginning of the Aviation in the pioneer era, pioneer era of aviation. The Wright brothers flew the ''Wright Flyer'' four times that day on land now part of the town of Kill Devil Hills, North Carolina, Kill Devil Hills, about south of Kitty Hawk, North Carolina. The aircraft was preserved and is now exhibited in the National Air and Space Museum in Washington, D.C. Design and construction The ''Flyer'' was based on the Wrights' experience testing gliders at Kitty Hawk between 1900 and 1902. Their last glider, the 1902 Wright Glider, 1902 Glider, led directly to the design of the ''Wright Flyer''. The Wrights built the aircraft in 1903 using Sitka spruce, spruce for straight ...
