Hot air balloon Hot air balloon Presentation Transcript

  • By Ms. Foran Mr. Taylor ’s Technology Class ACE April 24, 1981
  • Hot air balloons are the oldest SUCCESSFUL human-carrying flight technology. They have 2 parts: the bag or envelope and the gondola or wicker basket. They also need a source of heat. The heated air inside the envelope makes the balloon buoyant, which makes it rise. It can fly to extremely high altitudes.
  • Parts of a hot air balloon
    • As early as 200 A.D., the Chinese used small hot air balloons to pass visual signals between military units.
    • Two French brothers, Jacques-Etienne, aged 38, and Joseph-Michel Montgolfier, aged 43, developed the first hot air balloon. They were papermakers who were born in Annonay, France.
  • In June, 1783, the Montgolfier brothers launched their hot air balloon. It was a paper lined linen balloon, filled with hot smoke from a straw fire. It rose 6,000 feet. This balloon did not carry any passengers. In Sept, 1783, King Louis XVI witnessed the first balloon with passengers – a duck, a rooster and a sheep.
    • The Montgolfier brothers noticed that wood chips float over a fire and they realized that heated air collected inside a lightweight paper or fabric bag would cause the bag to rise. This led to their experimentation of capturing heated air in a balloon
    • Balloons were used during wartime for military observation during the Civil War. They were also used to carry mail out of Paris, over German lines during the Franco-Prussian War.
    • Today, balloons are mainly used for recreation
