Information About Hot Air Balloon
Hot Air Balloons operate best and safely when atmospheric air conditions are dry and stable with light winds. Early in the morning and early evening tend to provide the best conditions most of the year as during the middle of the day the heat of the sun generates thermals which make the balloon very difficult to control. You can often see examples of thermals when you see large puffy clouds building up in height in the sky. Balloons are also happier flying in lighter winds and so are the passengers. Winds are also generally lighter in the mornings and evenings. Both of these reasons explain why you rarely see a balloon flying in the middle of the day. However in cold winter climates when the weather is fine and stable it is very often possible to fly for most of the day due to the lack of thermic activity.
The Hot Air Balloon is remarkably simple in its conception and handling. The first hot air balloon was flown in 1783 in Paris using the materials available of the day. It consisted of a large bag to enclose the heat generated from a fire on the ground with a gondola attached to carry the people. 스포츠토토 The modern Hot Air Balloon consists of three main parts: Envelope (The large bag), fuel system (burner with load frame and fuel cylinders) and finally a basket of woven construction to carry the pilot and passengers. Envelopes are now made of high resistance polyamide fabric able to withstand high temperatures reinforced by polyester load tapes. These tapes carry the forces due to loading and transmit the forces to the load frame via stainless steel wires. Hot Air Ballooning. On September 19, 1783 Pilatre De Rozier, a scientist, launched the first hot air balloon called 'Aerostat Reveillon'. The passengers were a sheep, a duck and a rooster and the balloon stayed in the air for a grand total of 15 minutes before crashing back to the ground.
