Hang Gliding
Hang gliding is an air sport or recreational activity in which a pilot flies a light, non-motorised foot-launched 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 feet 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 ind ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gliding
Gliding is a recreational activity and competitive air sport in which pilots fly unpowered aircraft known as gliders or sailplanes using naturally occurring currents of rising air in the atmosphere to remain airborne. The word ''soaring'' is also used for the sport. Gliding as a sport began in the 1920s. Initially the objective was to increase the duration of flights but soon pilots attempted cross-country flights away from the place of launch. Improvements in aerodynamics and in the understanding of weather phenomena have allowed greater distances at higher average speeds. Long distances are now flown using any of the main sources of rising air: ridge lift, thermals and lee waves. When conditions are favourable, experienced pilots can now fly hundreds of kilometres before returning to their home airfields; occasionally flights of more than are achieved. Some competitive pilots fly in races around pre-defined courses. These gliding competitions test pilots' abilities t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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] |
Glider Aircraft
A glider is a fixed-wing aircraft that is supported in flight by the dynamic reaction of the air against its lifting surfaces, and whose free flight does not depend on an engine. Most gliders do not have an engine, although motor-gliders have small engines for extending their flight when necessary by sustaining the altitude (normally a sailplane relies on rising air to maintain altitude) with some being powerful enough to take off by self-launch. There are a wide variety of types differing in the construction of their wings, aerodynamic efficiency, location of the pilot, controls and intended purpose. Most exploit meteorological phenomena to maintain or gain height. Gliders are principally used for the air sports of gliding, hang gliding and paragliding. However some spacecraft have been designed to descend as gliders and in the past military gliders have been used in warfare. Some simple and familiar types of glider are toys such as paper planes and balsa wood gliders ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Gertrude Rogallo
Gertrude S. Rogallo (January 13, 1914 – January 28, 2008) was one of the co-inventors of the flexible wing. These wings are now known as Rogallo wings. She and her husband, Francis Rogallo, invented the wing and obtained two United States patents on different versions of it in the early 1950s. Rogallo wings are commonly used today in kites, hang gliders and powered hang glider A foot-launched powered hang glider (FLPHG), also called powered harness, nanolight, or hangmotor, is a powered hang glider harness with a motor and propeller in pusher configuration.

Paresev 1-B In Tow Flight - GPN-2000-000212
The NASA Paresev ("Paraglider Research Vehicle") was an experimental NASA glider aircraft based upon the kite-parachute studies by NASA engineer Francis Rogallo. Between 1961 and 1965 the ability of the Rogallo wing (also called "Parawing") to descend a payload such as the Gemini space capsule safely from high altitude to ground was studied.Aviation News article The Paresev was a test vehicle used to learn how to control this parachute-wing for a safe landing at a normal .

Octave Chanute
Octave Chanute (February 18, 1832 – November 23, 1910) was a French-American civil engineer and aviation pioneer. He provided many budding enthusiasts, including the Wright brothers, with help and advice, and helped to publicize their flying experiments. At his death he was hailed as the father of aviation and the initial concepts of the heavier-than-air flying machine. Biography Born in Paris, Chanute was the son of Elise and Joseph Chanut, professor at the Collège de France. He emigrated with his father to the United States of America in 1838, when the former was named Vice-President at Jefferson College in Louisiana. Octave attended private schools in New York. Civil engineer (railroads) Octave Chanute began his training as a budding civil engineer in 1848. He was widely considered brilliant and innovative in the engineering profession. During his career he designed and constructed the United States two biggest stockyards, Chicago Stock Yards (1865) and Kansas City ...
