The diagram illustrates the process involved in operating a hot air balloon.
Overall, this is a seven-step linear process that commences with the unfolding of the envelope, proceeds through the assembly of the balloon, and concludes with its landing.
The first step entails laying out the envelope. Subsequently, the balloon is inflated with air using an inflator fan. Once the butane tanks are securely positioned in the basket, the burner combines air with butane, producing warm, light, and dense air that fills the balloon.
Thereafter, the balloon begins its ascent. During the flight, a parachute valve situated at the top of the balloon regulates the ascent and facilitates a controlled descent. Finally, once the balloon has been deflated, it safely returns to the landing stage.
