Hot Air Ballon

A hot air balloon is a lighter-than-air aircraft that consists of a bag, called an envelope, that contains hot air. Suspended below is a gondola or wicker basket (in some long-distance or high-altitude balloons, a capsule), which carries passengers and a heat source, in most cases an open flame caused by burning liquid propane. . The warm air inside the envelope makes it buoyant since it has a lower density than the cooler air outside the envelope. As with all aircraft, hot air balloons cannot fly beyond the atmosphere. Unlike gas balloons, the envelope does not have to be sealed at the bottom, since the air near the bottom of the envelope is at the same pressure as the surrounding air.

In modern sports balloons, the envelope is usually made of nylon fabric and the balloon inlet (closest to the burner flame) is made of a flame-resistant material such as Nomex. Modern balloons have been manufactured in all types of shapes, such as rockets and shapes of various commercial products, although the traditional shape is used for most non-commercial and many commercial applications.
