operation mechanism of a hot air balloon.

operation mechanism of a hot air balloon. Ar2Q1
The illustration depicts the operation mechanism of a hot air balloon. Generally, there are three main components, including the envelope, the burner, and the basket. In addition, the hot air balloon works based on the principle of aerodynamic lift. Regarding the structure of the balloon, the biggest part is the envelope, which includes a valve, panel gores, and a skirt. Connected to the envelope with ropes are the burners, which are installed on a metal frame. Finally, the basket is the container on the bottom, providing space for the pilots and the propane cylinders. Considering how it works, after being inflated, propane mixed with regular air is burnt to produce hot air to be blown into the inside of the balloon. As hot air is lighter than cool air, the lift is created. Once the balloon is raised, its height is maintained by adjusting the burner and the valve, which allows hot air to escape at a controlled rate and prevents oscillations.
