The hot air balloon is considered a type of ship that allows people to move through the airspace, although in most cases such movement is simply recreational and temporary. The hot air balloon works from the movement of different gases that may or may not be hot. The impulse of these gases causes the chamber formed by a large cloth to move through the air, in addition to rising in height and detaching from the ground. Normally, hot air balloons do not fulfill a regular transport function as other air craft (planes, helicopters) do, but rather it is related more than anything to recreational activities, competitions, etc.
The hot air balloon is made up of three parts: first, and most important, is the chamber in which the air is contained. This chamber is formed by an extensive cloth that takes a shape similar to that of a drop and remains open at the bottom. It is in this part where the gas that will be used to mobilize the balloon and that keeps the fabric fully extended is inserted. It is very important that the air chamber does not present any holes or damage because then the movement of the propellant gas would not be adequate and the hot air balloon could fall.
Then there is the motor or thermostat, the one that propels the gas and that can be manually operated according to needs (for example, raise or lower the intensity of the air according to whether you need to go up or down in height). Finally, the third part is what is known as the gondola and which is where the passengers and crew of the balloon are located. This gondola is usually small and is tied to the fabric of the upper part by means of strong cords and ropes.
The operation of the hot air balloon depends precisely on the movement of the gas that is used as a propellant. This means that it is not electrical or mechanical but depends on the exchange of gases. There are two main types: those that are moved by hot air (that is, when the same oxygen that is inside the chamber is heated from the engine) and those balloons that use gases such as hydrogen, helium or methane gas that cause it to vary. the weight of the balloon in relation to the weight of the air in the atmosphere and thus it can ascend or descend.
