A training equipment "modified" from a missile booster is deeply applied to the daily training of the national speed skating team and the Chinese cross-country skiing team.
In the men's 500m final of speed skating at the Beijing Winter Olympics on February 12, China's Gao Tingyu won the gold medal in 34.32 seconds and set a new Olympic record. At the beijing Winter Olympics cross-country skiing women's 4×5 km relay final held on the same day, the Chinese team composed of Chi Chunxue, Li Xin, Bayani Garin and Ma Qinghua finished tenth with a time of 57 minutes 49.7 seconds, setting a new record for the Chinese team in the history of the Winter Olympics in the event. The two projects each made historic breakthroughs at the Winter Olympics, which is blessed by the concept of "science and technology to help the Olympic Games". According to the Global Times reporter, a training equipment "modified" from a missile booster is deeply applied to the daily training of the national speed skating team and the Chinese cross-country skiing national team.

The Global Times reporter recently learned from the third institute of the Eleventh Academy of China Aerospace Science and Technology that this set of training equipment was "transformed" by the researchers of the institute and the Beijing University of Aeronautics and Astronautics using small missiles and unmanned aerial vehicle engine technology. Zheng Liu, an engineer of the Third Institute of Aerospace Science and Technology Eleventh Academy who participated in the research and development of the equipment, said in an interview with the Global Times reporter that this set of aerodynamic principles based on the reverse thrust of the fan exhaust air, and the design and development of the hanse fan jet power training booster, according to the needs of training, can provide auxiliary thrust for cross-country skiing and speed skaters, so that athletes can break through their own physical energy limitations in training and carry out various extreme state training activities.
According to the Global Times reporter, this booster mainly includes power, thrust control and power supply and other devices. When in use, athletes only need to wear components to fix the booster weighing about 3.5 kg on the back and assist in training under the impetus of the power unit. The booster's thrust control device has a manual control function, which can artificially control the thrust size and start and stop of the booster in real time.
Zheng Liu said that the auxiliary role of this set of equipment for speed skaters is mainly reflected in two aspects, one is to help speed skaters reach a certain speed before cornering, so that athletes can carry out targeted practice of cornering technology, save athletes' physical strength in accelerating the starting acceleration of the straight stage, and improve the pertinence and efficiency of training. In addition, the equipment can also help speed skaters to break through their own speed limits, so that athletes feel the physical state at higher speed, "a typical speed skating training, athletes can increase their speed by 10% after 400 meters per lap." Zheng Liu introduced.
In addition, this set of equipment is also used in the daily training of the Chinese cross-country skiing team. Zheng Liu said that in cross-country skiing, athletes must not only have super endurance, but also require athletes to have excellent snow field adaptability, athletic ability and cornering skills. This device can use the "missile booster" technical principle to create a high-speed sports state for athletes, help athletes practice turning, lane change, jumping and other technical actions at high speed, so that athletes can break through the physical limit and form muscle memory in high-speed state, creating a new way of training in the extreme state.
Zheng Liu admits that he is very proud to be able to apply missile booster technology to the daily training of Chinese Winter Olympic athletes and help them achieve breakthrough results. "It is a great honor to be able to participate in the project of science and technology to help the Olympic Games, use our aerospace technology to help national athletes achieve better results, and make a little contribution to the Winter Olympics, at the same time, the athletes' fighting spirit also infects me, I believe that in my future work, I can also uphold the spirit of spaceflight and the spirit of the Olympic Games, and continue to contribute to the space industry."
