Why can t the torch be blown out by the wind? Thank you! Please, thank you

The design of the Beijing Olympic torch has strong Chinese characteristics, its shape design comes from the traditional Chinese paper scroll, and the lacquer red visual effect from the Han Dynasty is very eye-catching. The fuel used in the flare is propane, which does not pollute the environment and keeps burning in the event of strong winds of 65 kilometers per hour and heavy rain of 50 millimeters per hour. Xiangyun is inspired by Chinese paper scrolls The Beijing Olympic torch is 72 centimeters long and weighs 985 grams.

The contrasting colors of red and silver produce a striking visual effect, which is conducive to various forms of ** communication. The upper and lower proportions of the torch are evenly divided, and the auspicious cloud pattern and three-dimensional relief craft design make the whole torch elegant and gorgeous, and the connotation is heavy. The "auspicious clouds" pattern is inspired by the "symbiosis of origin, harmony and integration".

The cultural concept of Xiangyun has a time span of thousands of years in China and is a representative symbol of Chinese culture. The design of the torch shape is inspired by traditional Chinese paper scrolls. Paper is one of the four great inventions of China, which came to the West through the Silk Road, and human civilization also spread with the advent of paper.

Aluminum alloy and hollow plastic parts are very light The Beijing Olympic torch is designed with thin and high-quality aluminum alloy and hollow plastic parts in the process, which is very light and environmentally friendly. The Beijing Olympic torch is the product of China's independent design and development, and has complete intellectual property rights. The lower part of the torch is red and is held by the torchbearer, and the Beijing Olympic torch is creatively painted with rubber and leather.

The touch of this lacquer surface is close to the human body's **, when the torchbearer holds the Beijing Olympic torch, he will no longer feel a cold metallic texture, but as if he is holding tightly with the other hand. The use of rubber leather paint also solves the problem that the metal surface is smooth and easy to slip off. Propane will not pollute the environment after combustion The fuel used in the Beijing Olympic torch is propane, which is a cheap and commonly used fuel.

The burning time is 15 minutes, and the flame height is 25 to 30 cm at zero wind speed. Its main components are carbon and hydrogen, and after combustion, there is only carbon dioxide and water, and there are no other substances, which will not cause pollution to the environment. It is understood that because the flame color of propane gas combustion is bright yellow, such a color is easy to identify and meet the needs of television broadcasting and news photography.

The flare has reached a new level of technical height in terms of combustion stability and adaptability to the external environment, and can maintain burning in strong winds of 65 kilometers per hour and heavy rain of 50 millimeters per hour. The heat recovery tube heats the fuel to generate pressure The flare combustion system consists of three parts: a burner, a pressure stabilizing device, and a gas tank. The burner uses an innovative two-flame concept, i.e. a pre-combustion chamber and a main combustion chamber, which is the first of its kind in the design of an Olympic torch.

When the outside temperature is as low as -20 degrees Celsius, the atmospheric pressure generated by propane fuel is only 2 atmospheres, how to ensure the continuous energy supply of the flare at such a low atmospheric pressure? Regulators and return pipes will solve this problem. The heat recovery pipe used by the Beijing Olympic torch uses the heat generated by the torch combustion to heat the fuel, so that the fuel tank can generate enough pressure to support the torch without the help of external heating devices.

Answer The Olympic torch independently developed by China adopts many high-tech technologies and has reached a new technological height in terms of combustion stability and adaptability to the external environment, and because it involves military technology, the torch burning technology is also regarded as the core secret of the Beijing Olympic Organizing Committee. The fuel used for the Beijing Olympic torch is propane, the main components of which are carbon and hydrogen, and after combustion, there is only carbon dioxide and water, no other substances, and will not cause pollution to the environment. The torch burning technology is also the guarantee that the torch will go to heaven and earth.

As a symbol of the Olympic spirit, the flame is never extinguished. China, which has already sent a manned spacecraft into space, is not a difficult task from a technical point of view to send the flame to Mount Everest. More than 20,000 torches were needed for the entire Beijing Olympic torch relay, and according to the design specifications, each cost did not exceed 1,500 yuan.

So far, only 3 samples of torches have been produced.

Beautiful auspicious clouds, fiery red, quaint paper scrolls ......The 2008 Olympic torch "Xiangyun" has a perfect appearance. Beneath the beautiful appearance, "Xiangyun" beats a powerful "heart". Because during the relay of the Olympic torch, it may face various unexpected weather conditions, and strong winds and heavy rain will severely test the torch's burning technology.

In order to provide a reliable combustion system for the torch, the Aerospace Science and Industry Group contributed a reliable "core" to the Olympic flame. 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. The Beijing 2008 Olympic torch has reached a new level of technical height in terms of combustion stability and adaptability to the external environment, and can keep burning in strong winds of 65 kilometers per hour and heavy rain of 50 millimeters per hour.

The core of the torch is made of high-tech and will not be extinguished even if it falls to the ground Thank you, brother, give me 1 vote

The torch is a high-tech product, which means that the flame will never stop, and how can it be extinguished.

The internal combustion system of the torch is to install a set of equipment in the torch, so that the torch can be burned for a period of time in a variety of complex environments within a certain range after ignition, and the relay is completed. The 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.

An important innovation in the internal combustion system of the flare is the 'twin flame' scheme. After the gas flows out, part of it enters the main combustion chamber of the burner, forming a relatively full flame of diffusion outside the torch; The other part enters the pre-combustion chamber, and maintains a relatively small but very stable flame in the torch, if there is an extreme situation, the flame of the main combustion chamber is extinguished, and the pre-combustion chamber can still keep burning to ensure that the torch is not extinguished.
