The diagram illustrates the man-made process by which a hot air balloon is operated.
Overall, this seven-step linear process begins with unfolding the envelope, followed by assembling the balloon, and ends with the landing stage.
The first step is laying out the envelope. Then, the balloon is filled with air by using the inflator fan. After butane tanks are placed in the basket, the burner mixes air and butane and emits warm, light, and dense air, which fills the balloon.
Following this, the blimp starts its flight, and during this time, a parachute valve located on the top of the balloon slows the blimp’s ascent and controls its descent. Finally, when the balloon is deflated, it safely returns to the landing stage.
