A hot air balloon is a lighter-than-air vehicle with a large balloon-shaped upper half and a gondola-shaped lower half. Hot air balloons belong to escaping the earth with flaming romanticism.

Modern sports balloons are usually made of nylon fabric with fire resistant openings. The gondola can carry passengers and a heat source. Can be used for aviation sports, photography, tourism, etc.

The science behind hot air balloon liftoff.

1. The principle of hot air balloon flight.

Hot air balloons use hot air or certain gases, such as hydrogen or helium, which are less dense than the air outside the balloon to create buoyancy.

The hot air balloon mainly adjusts the temperature of the air in the air bag through its own on-board heater, so as to achieve the purpose of controlling the rise and fall of the balloon.

The basic principle of a hot air balloon is that it expands when heated and contracts when cold. When the air is heated and expanded, the specific gravity becomes lighter and rises upward.

2. The principle of hot air balloon lift-off.

The theory of hot air balloon flight is based on the theory of lift, which states that the gas contained in the balloon is lighter or denser than the surrounding atmosphere acting on the balloon.

It controls the rise and fall of the hot air balloon by adjusting the temperature of the hot air balloon through the interval between the ignition and extinguishing of the burner, and controls and adjusts its forward direction according to the wind direction at different heights.

It has the same speed as the wind.

Precautions for riding a hot air balloon.

1. Try to wear cotton fabrics and sneakers. Skirts, high heels, sandals, etc. are not suitable. To prevent burns, be sure to wear long clothes and trousers, and a cotton hat.

2. When the hot air balloon is ignited, it will instantly shoot out flames as high as 3 to 5 meters, and at the same time, it will make a loud explosion-like sound.

Therefore, the experiencer should be fully mentally prepared to grab the gondola when igniting.

3. The best time for a hot air balloon flight is within two hours after sunrise or within two hours before sunset, when the airflow is the most stable. The windy season is not suitable for hot air ballooning.

4. Know your tolerance. After all, you have to take a hot air balloon to the sky, and it will be very high off the ground.

If you are afraid of heights, you will not only be unable to enjoy the beautiful scenery, but also easily cause physical problems, so you must first understand whether your body or mind can bear it.

Is it safe to ride a hot air balloon?

The accident rate is very low. Generally speaking, as long as you follow the rules of riding a hot air balloon, the safety is still very high, but any activity is dangerous and there is no 100% safety.

It is important to have the relevant knowledge before taking a hot air balloon ride.

Stroll the sky and have a romantic hot air balloon date.
