The diagram shows the equipment and operation of a hot air balloon. Overall, a common air balloon comprises two main parts: a big envelope and some simple equipment users can access to change their height based on the thermal regulation of air. With regard to the construction of an air balloon, its upper part resembles an inverted onion, with the parachute valve at the top to allow users to control the rate at which hot air escapes. The envelope also consists of many 'gores', under whose coatings are a large number of panels. The lower part of the air balloon includes a skirt attached to a basket by ropes. There is a burner attached to the strap of the basket and two propane tanks inside of it. Turning next to how the balloon works, propane is released from the two containers, and is mixed with air, and the mixture is ignited by means of a burner, creating a flame. As the temperature inside the envelope increases, the air inside gets lighter, pulling the balloon upward. In order to fly lower, users can reduce how much propane and air are burned so that the envelope is filled with more cool air, which is heavier and consequently pulls the balloon downward.
