Gliders (sail planes) AE and AC
Transcript of Gliders (sail planes) AE and AC
Arinze Ebekonye Gliders
(Sail Planes) How does it Fly? Fun Facts History (Continued) The shape of a glider wing is an airfoil. This gives the wing lift. But a glider will fall to earth unless the pilot finds thermals to keep the glider up.
Thermals are warm currents of rising air. They are created when the sun shines on land, such as bare rock, that reflects heat. As the heated air rises, the glider can ride on the updrafts and stay up for hours.
Flying a sailplane is probably the closest thing any human will come to feeling like a bird. The glider originated in China in 500 B.C. A person of Confucius, named Lu Pan, built the first glider, but it was more of a toy and was not meant for manned flight. Leonardo Da Vinci became interested with flying machines. As part engineer, he created his own glider that resembled helicopters today. Percy Pilcher made wing designs for gliders. History Innovations Gliders were innovated into planes such as planes that do not require engines. (Such as seaplanes). Gliders have been innovated into landing gear for NASA’s space shuttles. Some innovated into hand gliding, recreational play. Gliders were used in the Spanish American War for use of better aim when missiles were launched. Otto Lilienthal built the glider and later made a two-wing glider. Octave Chanute, a civil engineer, created designs to try to take out movement in the glider's body. The Wright brothers used gliders in their work to achieve controlled and manned, powered and wing flight. And The glider idea came from the sugar glider! Gliders rely on air and lift for their performance
Space Shuttles use gliding wings to land on Earth
Glider wings a high aspect ratio: they are long compared to their width.
Gliders weren't made for manned use st first they were considered toys
Gliders Originated in China
