The picture below shows how a balloon works. Summarize the information by selecting and reporting the main features.
The given diagram illustrates the structure and operational principles of a hot air balloon.
Overall, it is apparent that a hot air balloon consists of several key elements: the envelope, the burner, propane cylinder, the skirt, the basket. Moreover, the diagram distinctly reveals the operational process of a standard hot air balloon with the upward movement of heated air.
As can be seen in the process, the largest component of the hot air balloon, also referred to as the envelope, is a fusion of the multiple fabric strips known for gores. These gores are carefully crafted by connecting numerous nylon panels together, collectively shaping the balloon when fully inflated. On top of the balloon, there is a parachute valve that allows it to open and close the air like a self-sealing flap. Its primary role is to enable control and release the air when the balloon works.
At the base of the envelope lies the skirt, integrally reinforced with flame- resistant material to endure with the heat pressure releasing from the burner. The burner, affixed to a metal flame beneath the skirt and above the passenger basket, serves as an engine, proficiency mixing propane with oxygen to generate the l hot air for the balloon.
In terms of operation, the burners facilitate the introduction of hot air into the envelope. This heated air is lighter than the surrounding cold air, thus generating a buoyant force that elevates the entire structure, enabling the hot air balloon to fly in the sky.
