About Hot air balloon
Source: Wikipedia, free encyclopedia
“The hot air balloon is a type of balloon, usually almost spherical, which, in order to float, uses the fact that the warm air (inside) has a lower density than that of the cooler air (from the outside). It’s the oldest flight technology developed by people. The first free flight of a hot air balloon took place on 21 November 1783 in Paris, France, and was made by Jean-François Pilâtre de Rozier and François Laurent d’Arlandes in a hot air balloon built on December 14,1782 by the Montgolfier brothers. Currently hot air balloons can have the most diverse shapes, ranging from rockets to sausages and bears. Passengers or cargo are transported to a platform that also contains a heat source, most often a burner facing the interior of the tire, releasing flames of up to 6 m in length in order to heat the indoor air. The fuel used for this purpose is propane or a mixture of propane and butane. The normal working pressure is between 5-10 bar. The heated air is directed towards the inside of the balloon tire and causes it to rise because its density is less than that of the outside air.“
