The two diagrams illustrate the main parts of a hot air balloon and indicate how it ascends and descends in flight. gGyyL
The figures illustrate how a hot air balloon ascends and descend thanks to a mechanical simple mechanism and hot gases provided by the burners. A balloon is composed by a spherical envelope, burners, a valve with a cord, gas tanks and a basket to transport safely the passengers off the ground. To ascend, the passenger opens the gas and switch on the burners, the hot air will fill the envelope while the inside valve is closed. Whereas, to descend the valve cord needs to be pulled in order to open the valve. It is important to note that burners must be off when the balloon is descending, on the contrary when it is ascending the burners are on. As It could be seen the entire procedure is executed by the operator inside the basket who must monitor the tanks, switch on the burners and pull the cord. To summarise, hot air balloon is a reliable transport when is in flight and could be easily operated using the mechanisms that has been explained.
