Chinese player Zhang Yu Fei won the championship in the women's 200 meter butterfly final, won the first Olympic gold medal for the Chinese swimming team and broke the Olympic record at the same time; (

The sports measurement team of 13 times optoelectronics companies of the ninth Academy of aerospace technology will take over this task. Times optoelectronics Co., Ltd. is an important inertial technology and product R & D base in China. It has always provided high-quality optical fiber inertial units and optical fiber rate gyroscopes for various types of rockets and aerospace vehicles in China < p > in swimming events, traditional image recording and other means can not quantitatively obtain all sports information of athletes, especially can not effectively identify such small changes as rotation between joints. Times optoelectronics successfully grafted the inertial technology applied to flying in the sky into swimming training, and used the inertial navigation subsystem to obtain the athletes' posture and breathing every second, as well as a number of technical parameters such as stroke frequency, stroke amplitude, stroke and turn time in the swimming pool, so as to realize the fine quantitative evaluation of each action < p > in the first half of this year, during the national swimming team's preparations for the Tokyo Olympic Games, the sports measurement team carried self-developed sports measurement products and cooperated with the national swimming team to carry out athlete wind tunnel tests. Six world champions including Zhang Yufei, Yang Junyu, Xu Jiayu, Liu Xiang, Yan Zibei and Yu Yiting participated in the experiment < p > the experiment simulates the flow field in the process of swimming, tests the posture and resistance of different technical movements under typical swimming speed, and explores the law of resistance of athletes under different postures under typical swimming speed, so as to provide a scientific basis for the coach team to determine the training scheme, improve the streamline of athletes and optimize technical movements < p > Zhang Yufei puts on the measuring equipment and is ready to start the test < / P > < p > from the appearance, this sports measurement product is really a bit like the "land tour" in the film, but @ state-owned Xiaoxin teases that it is definitely "the land tour that Wang Duoyu dare not invest" < p > netizens were silly: aerospace technology has played a role in the training of the Chinese swimming team. What is this? It's an unimaginable road < p > in fact, there is more than one aerospace technology to help the Chinese Olympic delegation win the championship. In addition to the inertial technology to capture fine movements, there is also an aerospace "black technology" - wind tunnel in the rowing project < p > according to the introduction of CASA, in 2019, according to the requirements of the four person rowing wind tunnel test project, the low-speed wind tunnel laboratory of Casa 11 successfully developed a three-dimensional force measurement platform. Through the wind tunnel test, the aerodynamic forces of athletes' different action postures such as grasping water, driving, leaving water and returning oar were studied, as well as the effects of different formation combinations of four athletes on aerodynamic resistance, Assist in Olympic training and competition and improve the competitive performance of Chinese athletes < p > the young members of the rowing team tried to train in the low-speed wind tunnel < / P > < p > the Chinese team composed of Chen Yunxia, Zhang Ling, LV Yang and Cui Xiaotong won the championship in the women's four person sculls final of the Tokyo Olympic Games on the 28th < p > figure self Vision China < / P > < p > in addition, in order to provide scientific and technological assistance for the preparation for the 2022 Beijing Winter Olympic Games, the 11th Academy of aerospace applied aerospace aerodynamic design and testing technology to many Olympic events by using the professional knowledge and scientific research achievements in design and wind tunnel testing accumulated in the aerospace field for many years, We have independently developed several sets of domestic leading high-precision test platforms to solve the problems of different test needs of various Olympic equipment < p > on October 25 last year, the first comprehensive sports training wind tunnel in China contracted by the 11th Academy of Astronautics was officially opened in CRRC 27th National Ice and snow sports training base, filling the gap that there is no large-scale comprehensive wind tunnel specially used for sports training and testing in China < p > overall appearance of sports wind tunnel < / P > < p > this wind tunnel is transformed from the diesel engine test station of Erqi plant, which reflects the purpose of "green Olympic Games" in China. Its performance is also at the leading level in the same industry, and is superior to the known foreign similar wind tunnels in terms of flow field quality and test accuracy < p > in addition, the sports wind tunnel is also a "training + scientific research" dual-function wind tunnel, which can not only carry out simulation training, but also accurately measure various test data for research, so as to improve the quality and efficiency of training < p > at present, many Olympic events have been interpreted as a comprehensive competition closely related to athletes and scientific and technological equipment. Using scientific and technological means to help Olympic training and competition can greatly improve the competitive performance of Chinese athletes, and has become one of the key factors supporting Olympic gold medals < p > as many netizens have concluded, a country's sports strength is inseparable from the display of national strength. "At the peak, it is actually the competition of national strength, and each medal is the embodiment of the country's comprehensive strength."
