According to the experience of the past two summer Olympic Games and previous Olympic Games, sudden gust and improper handling of relay race are the main reasons leading to the extinction of the flame. However, with the development of science and technology, all countries in the world have made unique achievements in this respect, and wind prevention has become the most basic and easy to solve problem of the Olympic torch.

1996 Atlanta Olympic torch is the longest torch in previous summer Olympic Games, and it is also the only torch that needs to be lifted in the middle. This torch is equipped with the latest windproof system made by American scientists, and it is reported that Lockheed's aircraft engine technology is adopted. This windproof technology using aircraft manufacturing technology ensures that the torch in 1996 will not be blown out by the wind, but compared with the torches in 2000 and 2004, the biggest problem is the insufficient burning of the torch in 1996.

The torch of the 2000 Sydney Olympic Games has a mass of 65,438+0,000 grams and can burn for 20 minutes. This fuel is a mixture of propane and butane, and it will still burn in the tropical area in the gale and rainstorm of 65 kilometers per hour.

This torch has comprehensively improved the combustion chamber, and also treated the key parts of the torch, adopting the "scattering" combustion technology. It is particularly worth mentioning that the automatic fire extinguishing device used in the torch design is the first time in the history of the Olympic torch. However, compared with the torch in 2004, it lacks sustainability, and too little fuel reserve is a big problem.

The torch of the 2004 Athens Olympic Games was designed as a whole for the first time. Because it is a mixture of propylene and butane as fuel, the flame of previous Olympic Games is the brightest. The torch is equipped with the most unique combustion chamber and self-ignition protection device. When it is blown out by the wind, the combustion chamber will rekindle the torch. Moreover, the spontaneous combustion protection device also appeared in the design of the Olympic torch for the first time.

Experts believe that the protection of torch spontaneous combustion in Athens Olympic Games has created new progress in the design of Olympic torch. However, compared with the Xiangyun Torch of the 2008 Beijing Olympic Games, experts believe that the manufacturing technology of the torch is still not as good as Xiangyun.

According to experts from China, the torch of the 2008 Beijing Olympic Games is based on the combustion technology of aircraft engines and rockets. The use of a very "mysterious" double-flame combustion system is the first time that human beings have applied rocket technology to the torch. And spreading in the plateau with thin air will also create human history. Carter, an American expert, said that the technology of Xiangyun Torch will be a precious legacy left by China to the world.

The torch of the 2008 Beijing Olympic Games is being passed around the world and has withstood the test of different meteorological conditions. Despite all kinds of difficulties in the torch relay, scholars and experts from all over the world unanimously said that the flame from ancient Olympia, Greece, will definitely light the main torch of the Beijing Olympic Games.
