1. Hot Air Balloon Principles
Hot air balloon flight is based on the principle that hot air is less dense than cold air. The same volume of hot
air is lighter than cold air, generating buoyancy. During ascent, the cold air inside the balloon is heated, raising
the temperature, making it lighter, and reducing its gravity to a level less than its buoyancy, allowing the
balloon to ascend. During descent, heating is stopped, causing the temperature inside the balloon to drop,
increasing its gravity. When the gravity exceeds its buoyancy, the balloon descends. Therefore, the ascent
and descent of the hot air balloon are controlled by adjusting the burner heating time and the balloon
temperature (gas density).
2. Hot Air Balloon Flight Methods
2.1 Tethered Flight
Three to four 60-meter-long tether ropes secure the balloon to the center of the flight area, allowing visitors to
experience the soaring experience. The balloon must operate within the ropes, ensuring that there are no
obstacles such as high-voltage power lines, light poles, or buildings. Hot air balloons are recognized by the
International Astronomical Union as the safest aircraft.
2.2 Free Flight
A hot air balloon has no rudder; its direction of movement must be determined by the wind. Wind direction
varies at different altitudes, times, and locations, requiring adjustment to different wind levels. Free flight,
without oxygen equipment, can be performed in varying wind directions. At an altitude of 3,000 meters, the
flight distance depends on the wind speed and direction
