IT House February 3 news, beijing 2022 Winter Olympics opening ceremony will be held on February 4, the torch relay is currently underway. The torch is called "Flying" and the color is silver and red, symbolizing the meeting of ice and fire.
The Beijing Aerospace Propulsion Institute issued an article today to unveil the scientific and technological highlights of the Beijing 2022 Winter Olympic Torch. According to reports, the winter Olympics handheld torch fuel is hydrogen, which is the world's first set of high-pressure hydrogen storage torches, achieving zero carbon emissions of torches in the history of the Winter Olympics.
Although the hydrogen is green, environmentally friendly and pollution-free, there are also "shortcomings" that are easy to explode, easy to leak, and are not easy to be found due to colorlessness and odorlessness when leaking, and the technical requirements are very high to achieve stable combustion for 5 minutes. In order to overcome the "shortcomings" of hydrogen and fit the shape of the handheld torch "flying", the handheld torch adopts a supporting high-pressure hydrogen storage scheme. The core combustion system holding the torch is led by 11 institutes (Beijing) and consists of three parts, from the bottom to the top, which are gas cylinders, hydrogen control valves and burners.
IT Home learned that torches can burn in various environments, inseparable from burners. In the design, it is not only necessary to meet the structural requirements of the complex surface features of "flying", but also to make innovative designs at the exit to achieve the visibility of the flame color and let the flame show the color.
In order to achieve high safety and stability, the development team conducted more than 300 reliability tests on the entire combustion system, so that the torch passed the test in extremely cold environments, ten-level winds, harsh rain and snow weather and other conditions.
