The diagram illustrates how the hot air balloon works and outlines the design of its the constituent parts. Moreover, the balloon depicts the processes in safely taking off and landing down.
Overall, the hot air balloon comprises main parts, including the envelope, skirt, burner and basket. Additionally, it has also extra support, consists of ropes and propane cylinder. One of the essential components of a hot air balloon is the envelope, which embraces gores, panels, and a parachute valve that controls the hot air outflow.
Initially, the burner brings the function of a central unit of the balloon, is attached to propane cylinder to make the hot air. When the balloon lit a flame, which is heated the air inside, fusing propane and air. Furthermore, the hot air balloon lifted because air inside processes less dense compared to the outer, cooler air.
On the other hand, when necessary, parachute valve will lower the altitude to let heated air escape on the top of the balloon. The skirt helps to stabilize the envelope base. Ropes are used to secure landing and takeoff. Finally, the basket has the function of carrying passengers as well as propane cylinder to power the burner.
