How the torch was lit As titled, thank you

The reasons why the torch can burn all the time are as follows:

In order to provide a reliable combustion system for the torch, aerospace science and industry.

The Group is the Olympic flame.

Contributed a reliable "core". The combustion system of this "core" consists of three parts: burner, pressure stabilizing device and gas tank. The burner adopts an innovative dual-flame concept, i.e. a pre-combustion chamber and a main combustion chamber.

For the first time in the design of the Olympic torch, the flame of the pre-combustion chamber will ensure that the flame of the torch will not be extinguished, even in windy weather, the pre-combustion chamber buried under the top of the torch will not be affected. The flame derived from the main combustion chamber will make the flame of the whole torch burn brightly, ensuring the visual effect of the torch.

Historical development

The first Olympic torch relay took place in Berlin, Germany in 1936.

held the 11th Olympic Games.

During the Summer Olympics.

Except for two without torches, the rest have torches, plus the Rio 2016 Olympic torch, a total of 19.

The shape of the torch has evolved over the course of history, such as the Athens Olympics.

The torch simulates the shape of an olive leaf, and the Beijing Olympics imitates a paper scroll. The London Olympic Torch incorporated 8,000 rings to pay tribute to the 8,000 torchbearers. In addition to its appearance, the Olympic torch is constantly integrated with the latest science and technology of various countries to ensure that it will not be extinguished for a long time.

However, there are always accidents, and during the torch relay, there will be various unexpected situations. So once the torch is extinguished, the torch must be ignited using the fire kept in the tinder lamp. There is a partition in the flare combustion chamber that divides it into a main combustion chamber and a pre-combustion chamber.

The two combustion chambers are combined, one is extinguished, and the other is lit by the tinder lamp. The Tinder Lantern is used to store the flame, and after the relay each day, the flame is kept in the torch until the next day when the torch relay starts again to relight the first potatoshi torch.

The structure and principle of the Olympic torch.

Unique "core" design.

Create your own flare internal combustion system.

In the design of the Olympic torch in recent years, only the shape design is generally carried out, and the internal combustion system is basically solved by purchasing the original molding technology. After careful study, the Beijing Olympic Organizing Committee decided to take the road of independent innovation and create our own internal combustion system of the torch.

The China Aerospace Science and Industry Corporation, which has strong scientific research strength, has become an active participant in the competition for this design scheme. To this end, dozens of capable scientific researchers in related fields of the group formed a design research team, and appointed Liu Xingzhou, an academician of the Chinese Academy of Engineering, as the chief designer of the torch internal combustion system.

To put it simply, the internal combustion system of the torch is to install a set of equipment in the torch, so that the torch can be kept burning for a period of time in various complex environments within a certain range after ignition to complete the relay transmission. Academician Liu Xingzhou said that the internal combustion system of the Beijing Olympic torch includes three parts, namely the burner, the pressure stabilizing device and the gas tank used to store gas. "We just had to set it up and secure it in a small, curved and irregular space.

The first thing that needs to be addressed is fuel. The Beijing Olympic torch chose propane. After the combustion of propane, it mainly produces water vapor and carbon dioxide, which will not cause pollution to the environment.

More importantly, propane can adapt to a relatively wide temperature range, and can still produce more than 1 saturated vapor pressure at minus 40 degrees Celsius, which is higher than the outside atmospheric pressure, forming combustion; Moreover, the flame produced by the propane has a bright yellow color, and the dynamically fluttering flame stands out against different backgrounds when the torchbearers run. b

The opening ceremony of the Beijing Olympic Games is becoming the focus of attention on the planet, and as long as human beings still have the desire to compete with each other and have the ambition to surpass themselves, then it is our unremitting pursuit to launch a grandiose, spectacular and surpassing the opening ceremony of the previous Olympic Games. Who will light the Olympic cauldron? How is the cauldron lit?

Possible index: 4 Of all the links in the opening ceremony, the ignition method of the cauldron tower is undoubtedly the most secret. The ceremony will also take place on August 8 at 11:30 p.m., the final moment of the opening ceremony.

During the "Good Luck Beijing" test match in April, many reporters searched for the cauldron in the stadium, but found nothing. I don't even know the location of the torch tower, and the secret of the ignition method is tightly covered. Although the ignition method was determined on 6 July, only 10 people in China knew about it.

It is said that this is a lot more than the practice of lighting a fire at the Sydney and Athens Olympics where only three people knew how to light the fire. "The unity of nature and man", this is the guiding ideology of the ignition method. It's just that this ancient philosophical term is profoundly abnormal, how should it be reflected in the way it is ignited?

A huge golden phoenix descends from the sky, she is a Chinese sacred bird and a symbol of rebirth from the fire. The golden phoenix circled and slowly fell to the torchbearer, who lit the phoenix, and the phoenix soared into the air and soared towards the deep night sky, and her beautiful figure could be seen throughout the city of Beijing, her beak spewed flames, the flames ignited the cauldron tower, and the Olympic flame rose into the sky, illuminating the beautiful bird's nest ......In June this year, there was a special construction project on the top of the Bird's Nest, and this reporter went to the scene to see it and found that it was a tower with a huge cover, a platform that "suspected" to take off and land a phoenix, and it could also be a main torch tower. Judging from the fireworks design of Cai Guoqiang, a pyrotechnic artist with rich artistic practice ability, it is entirely possible for him to design this golden phoenix dancing with the god of fire with the help of fireworks effects.

Also, when talking about the way to light the cauldron, Zhang Yimou, the chief director of the opening ceremony, once said, "This is a plan that can fly." And the return of the "immortal bird" phoenix, which symbolizes the ancient Chinese culture and the brave spirit in the bird's nest, is so imaginative and how tense is the performance? Beg.

Flying Golden Phoenix Lights the Cauldron A huge golden phoenix descends from the sky, she is the sacred bird of China, a symbol of rebirth from the fire. The golden phoenix hovers.

In a circle, it slowly fell to the torchbearer, and the torchbearer ignited the phoenix, and the phoenix rose into the air, towards the deep.

The night sky soared, and her beautiful figure could be seen throughout the city of Beijing, her beak spewing flames, and the flames ignited.

The main cauldron tower, the Olympic flame rises into the sky, illuminating the beautiful bird's nest ......

In June this year, there was a special construction on the top of the Bird's Nest, and the reporter of this newspaper went to the scene to see it and found this.

It is a tower with a huge cover, a platform for take-off and landing of the "suspected" Phoenix, and it is also possible that the main one.

Torch Tower. Judging from the fireworks artist Cai Guoqiang, who has rich artistic practice ability, is responsible for the fireworks design, he is finished.

It is possible to use fireworks effects to design this golden phoenix dancing with the god of fire. Also, when it comes to igniting the Lord.

When the torch was carried out, Zhang Yimou, the chief director of the opening ceremony, once said, "This is a flying plan." And in the bird's nest.

How imaginative is the return of the "immortal bird" Phoenix, which symbolizes the ancient Chinese culture and the brave spirit.

How tense is the performance?
