The glory and dream of Dongfeng Aerospace people
2022-12-05
Jiuquan Satellite Launch Center made great efforts to make contributions to China's manned space industry - the glory and dream of Dongfeng spacemen On the evening of November 29, 2022, the Gobi Desert was quiet. The survey hall of Jiuquan Satellite Launch Center is brightly lit. The Shenzhou 15 manned flight mission is undergoing pre launch functional inspection. This night will surely be recorded in the annals of China's manned space flight. Zheng Yonghuang, the chief engineer of the center, stared at the computer screen in front of him. "5, 4, 3, 2, 1, ignition!" With the firing command of Commander Wu Hua of No. 0 sounded, the Long March 2F Remote 15 carrier rocket lifted the Shenzhou 15 manned spaceship to the sky and flew to the vast universe. Hearing the news that the spaceship was launched into orbit, Zheng Yonghuang was excited. Great dreams breed great undertakings. On the same day 10 years ago, President Xi pointed out during his visit to the "Road to Revival" exhibition: "Now, everyone is talking about the Chinese Dream. I think realizing the great rejuvenation of the Chinese nation is the greatest dream of the Chinese nation since modern times." The Chinese Dream contains the space dream, and the space dream helps the Chinese Dream. This is the end of the construction phase of China's space station, attracting worldwide attention. As a technical expert in the field of manned space flight, Zheng Yonghuang participated in the foundation laying and construction of manned space launch site, and participated in all previous Shenzhou spacecraft launch missions. This time, he will witness the historic moment when two groups of astronauts are on orbit at the same time. "It is the honor and dream of all Dongfeng astronauts to realize their dreams of space!" Zheng Yonghuang said excitedly. The Shenzhou spaceship set sail from here, and the flying dream spread its wings. In the 1990s, China's manned space program was officially launched. As the project site is set at Jiuquan Satellite Launch Center, Dongfeng Aerospace City, a small Gobi city, has become inextricably bound up with manned spaceflight. Groups of aerospace personnel gathered here from all over the world to integrate their personal dreams into the country's aerospace industry. As one of them, young Zheng Yonghuang came to Dongfeng Space City with full vision. After years of planning, design, research and demonstration, China Aerospace's most complex launch tower and Asia's first vertical assembly test plant have turned from drawings into reality here. A modern manned space launch site has sprung up in the Gobi Desert. The manned space project involves 14 large systems, and the test and launch process is very different from that of ordinary satellite missions. After repeated research, Zheng Yonghuang and his colleagues compiled China's first manned space mission test and launch process under the "three verticals" mode of vertical assembly, vertical testing and vertical transition, opening up a new pattern of China's space launch system. In July 1999, the train from Beijing, carrying rockets and spaceships, arrived at Jiuquan Qingshui Station and turned to the manned space launch site. The launch mission of Shenzhou-1 airship was fully launched. "In that task, our measurement and control communication system adopted many new technologies and systems, with an unprecedented number of types and quantities of equipment, as well as arduous and complex installation and debugging." Li Chunfeng, an expert in measurement, control and communication systems, remembers the Shenzhou spaceship's first exploration of space. The Shenzhou I mission requires that all data of the rocket and spacecraft can be processed and displayed in real time. To this end, Li Chunfeng led his colleague Fu Ming and team members to independently develop a set of command and control, network
