History Of Hang Gliding
Hang gliding is an air sport employing a foot-launchable aircraft. Typically, a modern hang glider is constructed of an aluminium alloy or composite-framed fabric wing. The pilot is ensconced in a harness suspended from the airframe, and exercises control by shifting body weight in opposition to a control frame. Overview Early hang glider designs did not enable reliable safe flight, their builders lacking a comprehensive understanding of the underlying principles of flight. The first recorded ''controlled'' flights were by German engineer Otto Lilienthal, whose research, published in 1889, strongly influenced later designers. That same year, similar designs were also successfully employed in Calabria, Italy by aeronautics inventor and artist, Vincenzo Raschella. The types of aircraft employed by Lilienthal and Raschella are now referred to as hang gliders. Further hang glider research was undertaken during the 1920s in Europe, Australia and the US, where designers tested sever ...

Hang Glider
Hang gliding is an air sport or recreational activity in which a pilot flies a light, non-motorised, fixed-wing heavier-than-air aircraft called a hang glider. Most modern hang gliders are made of an aluminium alloy or composite frame covered with synthetic sailcloth to form a wing. Typically the pilot is in a harness suspended from the airframe, and controls the aircraft by shifting body weight in opposition to a control frame. Early hang gliders had a low lift-to-drag ratio, so pilots were restricted to gliding down small hills. By the 1980s this ratio significantly improved, and since then pilots have been able to soar for hours, gain thousands of meters of altitude in thermal updrafts, perform aerobatics, and glide cross-country for hundreds of kilometers. The Federation Aeronautique Internationale and national airspace governing organisations control some regulatory aspects of hang gliding. Obtaining the safety benefits of being instructed is highly recommended and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sputnik
Sputnik 1 (, , ''Satellite 1''), sometimes referred to as simply Sputnik, was the first artificial Earth satellite. It was launched into an elliptical low Earth orbit by the Soviet Union on 4 October 1957 as part of the Soviet space program. It sent a radio signal back to Earth for three weeks before its three silver-zinc batteries became depleted. Aerodynamic drag caused it to fall back into the atmosphere on 4 January 1958. It was a polished metal sphere in diameter with four external radio antennas to broadcast radio pulses. Its radio signal was easily detectable by amateur radio operators, and the 65° orbital inclination made its flight path cover virtually the entire inhabited Earth. The satellite's success was unanticipated by the United States. This precipitated the American Sputnik crisis and triggered the Space Race. The launch was the beginning of a new era of political, military, technological, and scientific developments. The word ''sputnik'' is Russian for ...

Langley Research Center
The Langley Research Center (LaRC or NASA Langley), located in Hampton, Virginia, near the Chesapeake Bay front of Langley Air Force Base, is the oldest of NASA's field centers. LaRC has focused primarily on aeronautical research but has also tested space hardware such as the Apollo Lunar Module. In addition, many of the earliest high-profile space missions were planned and designed on-site. Langley was also considered a potential site for NASA's Manned Spacecraft Center prior to the eventual selection of Houston, Texas. Established in 1917 by the National Advisory Committee for Aeronautics (NACA), the research center devotes two-thirds of its programs to aeronautics and the rest to space. LaRC researchers use more than 40 wind tunnels to study and improve aircraft and spacecraft safety, performance, and efficiency. Between 1958 and 1963, when NASA (the successor agency to NACA) started Project Mercury, LaRC served as the main office of the Space Task Group. In September 201 ...

Francis Rogallo
Francis Melvin Rogallo (January 27, 1912 – September 1, 2009) was an American aeronautical engineer inventor born in Sanger, California, U.S. Together with his wife, he is credited with the invention of the Rogallo wing, or "flexible wing", a precursor to the modern hang glider and paraglider. His patents were ranged over mechanical utility patents and ornamental design patents for wing controls, airfoils, target kite, flexible wing, and advanced configurations for flexible wing vehicles. Career Francis Rogallo earned an aeronautical engineering degree at Stanford University in 1935. Since 1936, Rogallo worked for the National Advisory Committee for Aeronautics (NACA) as an aeronautics project engineer at the wind tunnels. During 1948, he and his wife, Gertrude Rogallo, invented and patented a self-inflating flexible kite. They called this kite the "flexible wing". Rogallo had originally invented the wing with the idea to create an aircraft which would be simple enou ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Henri Mignet (19 October 1893 – 31 August 1965) was a French radio engineer who became well known as an aircraft designer and builder.Ellis & Jones (1990)Plane and Pilot: ''1978 Aircraft Directory'', page 142. Werner & Werner Corp, Santa Monica CA, 1977. His most famous design is the ''Flying Flea'' family of aircraft. Early interest in aviation Mignet was born in Charente-Maritime. In 1911, when he was 18 years old, he started corresponding with Gustav Lilienthal (the brother of Otto Lilienthal) about aviation. In 1912, he built his first aircraft, the HM.1-1 model. It was a monoplane inspired by the creations of Otto Lilienthal. Service in the First World War Between 1914 and 1918, Mignet served in the French army. He was a radio operator during World War I. In 1918, he was hospitalized with malaria. Post World War I designs In 1920, Mignet finished his first powered aircraft prototype, the HM.2.

Alexander Lippisch
Alexander Martin Lippisch (2 November 1894 – 11 February 1976) was a German aeronautical engineer, a pioneer of aerodynamics who made important contributions to the understanding of tailless aircraft, delta wings and the ground effect in aircraft, ground effect, and also worked in the U.S. Within the Opel-RAK program, he was the designer of the world's first rocket-powered glider. He developed and conceptualized delta wing designs which functioned practically in supersonic delta wing fighter aircraft as well as in hang gliders. People he worked with continued the development of the delta wing and supersonic flight concepts over the 20th century.

Rhön-Rossitten Gesellschaft
The Rhön-Rossitten Gesellschaft (RRG) or Rhön-Rossitten Society was a German gliding organization, the first one in the world that was officially recognised. The Rhön-Rossitten Gesellschaft was mainly responsible for establishing gliding as a sport, not only in Germany but eventually throughout the world. Because the Treaty of Versailles forbade any form of powered flight in Germany, many young pilots and aircraft designers turned to gliding as a sport. Under Oskar UrsinusReitsch, H., 1955, The Sky My Kingdom, London: Biddles Limited, Guildford and King's Lynn, and Theodore von Kármán, hobbyists and serious university study groups began building gliders. The first contest was held in 1920 on the mountain of the Wasserkuppe in the Rhön region of Hesse. While many of the entering designs were no more than kites and many of the 'flights' were no more than stumbles ending in a crash, Kármán and his team from the RWTH Aachen with their glider ''Schwarzer Teufel'' (Black Devil) ...

Wasserkuppe
The Wasserkuppe (;) is the highest mountain in the Rhön Mountains, Rhön range and the tallest elevation in the Germany, German state of Hesse, standing at above sea level. It forms a prominent plateau within the Fulda district and is known as the "cradle of gliding". Great advances in sailplane development took place here during the Aviation between the World Wars, interwar period, driven by annual contests. To this day, an airfield near the summit continues to be used by gliding clubs and light aircraft pilots. Etymology The German language, German name is derived from ''Wasenkuppe, Asenberg'' or ''Weideberg'' and means ''Pasture mountain''. Geography The Wasserkuppe lies in the administrative district Fulda (district), Fulda north of Gersfeld. Other villages nearby are Poppenhausen, Hesse, Poppenhausen ( west - south west) and Wüstensachsen ( east, part of Ehrenberg, Hesse). It is part of the Rhön Biosphere Reserve.
