Milestones in aviation history

  1. 1. MILESTONES IN AVIATION HISTORY (EARLY FLIERS)) Joha rahman http://pramugari.info/
  2. 2. THE EARLY EXPERIENCES  Dated back as early as 400 BC, an unknown Greek scholar had build a wooden pigeon that was able to fly in circle. How exactly he did it is unrecorded.  The early Chinese built kites that were big enough to enable people to ride on them. They were early gliders, but had to have strings attached.  Source: http://www.ueet.nasa.gov/StudentSite/historyofflight.html
  3. 3. EARLY ATTEMPTS TO FLY  In 1500 Leonardo da Vinci came up with early design of flying machine, known as ornithopters.  The early attempts emulate the flight of the birds, with flipping wings, all attempts failed as our hands are not strong enough to flap the big surfaces.
  4. 4. BALLOONS FLIGHT  Montgolfier brothers demonstrated in 1783 using balloons about 100 feet in diameter, filled with hot air was able to travel more than 6000 feet.  However the flight lack the directional control, leaving it to the mercy of the blowing wind.
  5. 5. BALLOONS FLIGHTS  The problem of directional control was overcome by making the balloon elongated and providing the powered thrust.  The most famous of the balloon generation was the Zeppelin in 1930s. Zeppelin was making trips across the Atlantic with the cruise speed about 68mph.  The era ended with the tragedy of Hindenburg, when the balloon caught fire on landing.
  6. 6. EARLY GLIDERS  In 1804, Cayley, a British built the first successful glider. This is the sparked up the idea that flying can be achieved by using a fixed wing design and a power unit to push the glider.  The first man to fly was a boy of unknown name.
  7. 7. BIRTH OF GLIDER  Around 1890, a German Lilienthal, developed the first controllable glider.  He was fascinated by the idea of flight based on the flying birds. He wrote a book on aerodynamics in 1889 and his text was used by the Wright Brothers as the basis for their designs.  After more than 2500 flights, he was killed when he lost control of his glider.
  8. 8. WORKS IN USA  Samuel Langley who started to build the foundation of the present airplanes  He knew that a power unit was required, and based on the technology available at that time, he built an airplane powered by steam.  In 1891, his model just managed to lift of the ground. He was frustrated and gave up
  9. 9. THE RESOURCE Blog site: http://pramugari.info/ The author had work with an international airline for more than 35 years, the last 10 years in Training and development. eMail : mktg@joharahman.com Appreciation: Source: http://www.ueet.nasa.gov/StudentSite/historyofflight.html
