The computer screen of an air traffic controller shows that the traffic in the airspace is as busy as the motor traffic on the streets of any cosmopolitan city. Jet engines boom around the world in hours and rockets routinely zoom in space. But it all started off with an unfashionable giant floating bag known as hot-air balloon. It is the oldest successful human flight technology. It is also called lighter-than-air flight because it contains heated air and is flown at low altitudes for short flights using winds. Hot-air balloon is one of the most delightful devices invented by human being and is fascinating to watch. It is a simple equipment that is relatively affordable when compared to other aircraft.

Components

A basket, a burner and an envelope make up a hot-air balloon. People have been using these same three components for hot-air balloon ever since its invention in the 18th century. Although the sophistication level is higher now, it is still composed of just those three things. The only difference is that advanced technology has enabled it to fly higher, faster and safer.

Exploring the workings of hot-air balloon starts with examining the fascinating evolution of its basket. It is the lowest part of the balloon and is suspended beneath the burner. It carries the propane gas tank, the pilot, the passengers and other vital instruments.

The pilot uses temperature to ascend and descend as well as to control the vessel’s motion once aloft. And burner is the tool that he or she uses to control temperature. It is the unit that produces and propels hot air into the envelope. That is why burner is the engine of the balloon.

3) Envelope

Two most important components of balloon envelope are its fabric and vents. Envelope volume goes by the cube of its diameter and the area by its square. Envelopes range in size from 77,000 to 600,000 c. ft. It can expect to last 350 flying hours. The mechanism by which envelope operates is rather complex
