The XXIV Winter Olympics kicked off in Beijing on February 4, 2022. The Sports Department of China News Network launched a series of columns "100 Questions about the Winter Olympics", which aims to popularize the knowledge of the Winter Olympics, answer hot questions, and talk about ice and snow anecdotes, so as to help everyone have a better viewing experience during the Beijing Winter Olympics.
No. 103 Winter Olympics 100 Questions | The torch on the "snowflake", where does the fuel come from?
At the opening ceremony on February 4, cross-country skier Diniger Yilamujiang and Nordic biathlete Zhao Jiawen embedded the last torch into the main torch table in the shape of a large snowflake. Some people will ask, how to achieve the energy supply to the torch?
Originally, the designers hid the cylinder in 5 "petals", but the replacement of the cylinder was a problem. In order to ensure the reliability of the torch, the technical team set the energy supply path in the sky.
The relevant person in charge said in an interview with the media, "There are more than a dozen motors composed of steel cable lifting system, as well as the release system of the gas circuit, the release system of the cable, and the winding and discharging system, so the gas path is on it."
In addition to the energy supply path, WEIA is also equipped with such as retractable cables, control lines, etc., forming a set of attitude adjustment actuators to cooperate with the ground device to achieve the action of the main torch. It can be said that the success of the torch platform energy supply is not only a stroke of China's great color in the Olympic Games, but also fully reflects the technological accumulation of China's aerospace in the field of hydrogen energy supply and utilization.
In addition, most of the fuels used in previous Olympic Games have been liquefied natural gas or propane and other gases, and this Beijing Winter Olympics is the first time that hydrogen energy has been used as a torch fuel, which is in line with the concept of green Olympic Games. (End)
