A balloon that uses hot air as the buoyant gas. There are large openings and hanging baskets for cold air heating at the bottom of the air bag. The density of air decreases after heating. When the temperature reaches 100°C, the density is about 0.95kg/m3, which is 1/1.3 of air, so the lift-off is not high. Modern hot air balloons are equipped with simple flight instruments, fuel tanks, blowtorches and other equipment in the gondola. When lifting off from the ground, ignite the blowtorch, heat the air and inflate it into the air bag from the bottom opening of the air bag. After taking off and flying, control the amount of fuel injection from the blowtorch to control the rise or fall of the balloon. Hot air balloons appeared first, and flying in hot air balloons has become a popular aviation sport. In addition, hot air balloons are also commonly used in aerial photography and aviation tourism.
