The basic principle behind a hot air balloon is that hot air rises, and when trapped inside a balloon, it causes the balloon to float upwards. The balloon consists of a large envelope made of lightweight, heat-resistant fabric such as nylon, which is filled with hot air by a burner located beneath the basket.
To begin the flight, the burner heats the air inside the envelope, which in turn heats the air inside the balloon. As the air inside the balloon becomes hotter than the air outside, it becomes less dense and rises, causing the balloon to lift off the ground. The pilot can control the altitude of the balloon by adjusting the intensity of the burner, allowing it to rise or descend as necessary.
The basket, which is typically made of wicker or another lightweight and sturdy material, is suspended beneath the envelope by strong cables. This allows passengers to stand in the basket and enjoy the view while the balloon floats gently through the air.
To land the balloon, the pilot reduces the intensity of the burner and allows the air inside the envelope to cool down, causing the balloon to descend gradually. The landing itself is typically quite gentle, as the basket is cushioned by the soft ground beneath it.
Overall, hot air balloons are a simple but effective way to experience the thrill of flight and enjoy breathtaking views from above.
