Who made the Shenzhou VII rocket? On September 25th, the Shenzhou VII manned spacecraft will be launched, and the eyes of the world will focus on China. From 1999, the unmanned Shenzhou-1 spacecraft visited space for the first time. In 2003, Yang Liwei walked out of Shenzhou 5's space capsule, and in 2005, Long Jun and Nie Haisheng flew hand in hand on Shenzhou VI. In the past six years, shenzhou spaceship has not only created the glory of manned space flight in China, but also created a number of well-known aerospace basic industrial enterprises, among which "Made in Henan" in shenzhou spaceship is even more eye-catching. In shenzhou spaceship, Henan enterprises not only undertake the production of key radio measurement and control systems, but also involve the design and manufacture of key components such as electrical parts, precision castings and precision bearings. The rocket propellant used for launching spacecraft and the cement used for launching diversion trough also come from Henan. Evening News reporter product Shenzhou core part bearing On the morning of September 18, a chilly autumn rain arrived as scheduled. Deng Haimin, the chief employee wearing blue tooling, carefully took out a product from the machine tool in front of a grinder in workshop 1 of Luoyang LYC Bearing Co., Ltd. 03 1 Bearing Factory. "Shenzhou Tian Fei has the credit of our ordinary workshop workers in Los Angeles and I am very proud to produce bearings for shenzhou spaceship." He said, in his spare time. From Shenzhou-1 to Shenzhou-7, LYC brand bearings have been produced for shenzhou spaceship for seven consecutive times. According to reports, these bearings are difficult to manufacture and have high precision, creating many of the best in China. LYC is also the only manufacturer of Shenzhou bearings that has been commended by China Manned Space Engineering Office. In 2006, the development of shenzhou spaceship series bearings won the "First Prize of Scientific and Technological Progress of the Provincial Commission of Science, Technology and Industry for National Defense". When Shenzhou VI was launched, LYC bearings provided 7 kinds of 22 kinds of bearings, all of which were in the core and key parts, including bearings for life support system, bearings for power supply system, bearings for attitude control system of orbital module and bearings for inertial navigation system of spacecraft launch vehicle. At present, LYC bearings have been widely used in shenzhou spaceship's driving devices and measurement and control radar systems. The bearings used in the key components of the Long March II rocket engine are also provided by LYC. In addition, Luoyang Axial Research Technology Co., Ltd. is a high-tech military enterprise, which has developed a variety of aerospace precision bearings, including solar panel bearings. "We are a national super-large enterprise and have the responsibility and obligation to contribute to the national defense and aerospace industry. We are honored. " A person in charge of the company said. Citic heavy industries, the manufacturer of escape engine, has been going west from Luoyang LYC Bearing Co., Ltd. to citic heavy industries Machinery Co., Ltd. (citic heavy industries for short) for about three stops. On the afternoon of September 18 1: 30, although it is not working time, many young people have gone out to work from high-rise apartments in citic heavy industries. "Our company has made many precision forgings for the Shenzhou series spacecraft, and the production process is very complicated. I haven't had a chance to participate. " When he said this, Zhang Ming with glasses seemed a little proud and yearning. In the reception room of citic heavy industries East Gate, a big photo of Shenzhou VI spacecraft taking off is very eye-catching. Here is a commendation message from the National Manned Space Engineering Office. The engine shell forgings of the escape cabin of Shenzhou VI manned spacecraft were made in citic heavy industries, and their aerospace forgings won the title of high-quality parts of China Shenzhou manned spacecraft. The shape of escape engine is irregular and its structure is quite complicated. When the rocket takes off, if there is a serious threat to the safety of astronauts, the escape engine on the escape tower will ignite and take off, separate the escape tower from the rocket and land the spacecraft safely on the ground. Because the forging engine shell is made of special materials, it is very difficult to make it, so the company has set up a special scientific research team. After a long period of independent research and development and technical research, we finally produced excellent aerospace forgings. Zhengzhou Dengfeng Smelting Co., Ltd., the manufacturer of product launch pad diversion trough, "The diversion trough of Jiuquan Satellite Launch Site used thousands of tons of cement, and our technicians personally directed the construction in March and May this year." September 17, Zhong Huafeng, the office of Zhengzhou Dengfeng Melting Materials Co., Ltd. said. Zhengzhou Dengfeng Melting Materials Co., Ltd. participated in China Aerospace 1994. At that time, after the four launches of the Long March II bundled rocket and the 1 Long March 3A carrier rocket at the xichang satellite launch center launch site, the diversion channel was seriously ablated, the refractory concrete flaked off in pieces, and the steel mesh was exposed, forming pits, which directly affected the safe launch of the carrier rockets. Relevant departments consulted relevant cases and found Dengfeng Melting Materials Co., Ltd., which was still a village factory at that time. After several launch tests, the company's cement became the special cement for the launch center. When China launched the first Dongfanghong artificial earth satellite, the water-cooled steel plate was used as the impact zone, surrounded by ordinary refractory materials, and it was completely damaged after only one launch. But at present, all Jiuquan and xichang satellite launch center in China use duck brand aluminate cement from Zhengzhou Dengfeng Melting Materials Co., Ltd. to build concrete diversion canals. Can be used for many times without maintenance, usually without maintenance, and has low cost. Shuguang Chemical Research Institute, a product rocket propellant manufacturer, "can't guarantee that Shenzhou VII spacecraft can finally use our rocket propellant, but it will definitely use it." On September 17, Yan Ma of the Propaganda Office of the Committee of Liming Chemical Research Institute said. Dawn Institute of Chemical Industry is the birthplace of China aerospace chemical propellant, and Li Junxian, an academician of China Academy of Engineering, is the first person to develop chemical propellant in China. The main propulsion fuels developed by the Institute for Shenzhou 5, the manned spacecraft No.6 and the Long March -2F rocket have reached the world advanced level. Due to the successful supply of high-energy chemical propellant for the Shenzhou manned spacecraft and its launch vehicle, Liming Institute of Chemical Industry won the honorary certificate and medal jointly issued by China Manned Space Engineering Office and China Aerospace Science and Technology Corporation. From the launch of China's first Dongfanghong satellite to Shenzhou VI in 1970, Liming Chemical Industry Research Institute has been providing various chemical power materials for China's rocket and space industry, filling many gaps in China's space industry and national defense construction. The fuel used in the escape system of Shenzhou series spacecraft is solid propellant developed by Liming Chemical Research Institute. Under the action of propellant, the escape capsule may take the spacecraft away from the dangerous area when the rocket fails unexpectedly during launch and liftoff, thus ensuring the safety of astronauts. At the same time, the liquid propellant developed by Liming Chemical Research Institute is also used as the main fuel for spacecraft attitude control, orbital module attitude control and return module landing thrust engine. When Shenzhou VI was launched, Liming Chemical Research Institute provided 3 tons of 5 kinds of propellant raw materials. 19 At 9: 00 am on September 9, Zhengzhou, the 27th Research Institute of China Electronics Technology Group Corporation, a manufacturer of product measurement and control and communication systems, was still busy. A staff member of the institute's office is sorting out the historical data of the institute's participation in China's space industry in the past 40 years. From the development of 1967 electronic TT&C system with two missiles and one satellite to the TT&C and communication before and after each flight in shenzhou spaceship, No.27 Institute has always been involved. It is understood that TT&C and communication systems of the spacecraft in the return, reentry and landing phases of the "Shenzhou VII" launch site were developed by the Institute. Since the first flight of China manned spacecraft, three sets of vehicle-mounted mobile stations for radio measurement, control and communication developed by the 27th Institute have been put into service in the space launch site. With the different needs of each flight and various technical feedback information, before the launch of Shenzhou, No.27 Institute had to carry out numerous experiments on the basis of the original system and update and improve it. For example, the radio measurement and control system used by Shenzhou VII adopted a new technology that can fill the gap in China after innovation. Among the seven systems in shenzhou spaceship, the measurement and control and communication systems are very important. A staff member of the institute said that, for example, the spacecraft is like a kite, the monitoring stations and ocean-going survey ships distributed in the three oceans are the kite-pulling lines, and the ground control system is like a kite-flying person. The overall design level of monitoring and communication is directly related to many safety problems of manned spacecraft. Landing field system is one of the most critical links for astronauts to return to the ground safely. After flying in space, the spacecraft began to re-enter the atmosphere from the return capsule, and used advanced radio measurement system to capture, analyze and predict the landing point of the target, then organized a rapid approach to the return capsule, disposed of the return capsule, and finally transported it safely to the base. Henan enterprises witness China's space power. "In addition to these manufacturers who undertake the task of supporting and supporting shenzhou spaceship, many enterprises in our province are also making contributions to China's space industry in obscurity." A staff member of Henan Association for Science and Technology told the reporter. Zhengzhou Metal Products Research Institute, which is capable of designing special-shaped steel wire equipment, developing special-shaped steel wire products and detecting special-shaped steel wire pass processing, has developed special parachute wire ropes for spacecraft's high-speed return flight, each wire rope can bear up to 300 kilograms of force, ensuring the safe and stable "soft landing" of the return cabin. The strapdown attitude measuring instrument developed by Luoyang 6 13 Research Institute will accurately measure the landing attitude of Shenzhou series spacecraft with acceleration below10000m. Luoyang High-tech Zone 158 Factory undertook the development and production of tens of thousands of electronic connectors for Shenzhou. WISCO has provided a variety of high-quality steel plates for shenzhou spaceship and the rocket launching bracket. The accessories produced by Xinxiang Bashan Precision Filter Material Co., Ltd. are applied in shenzhou spaceship. Factory 693 of Aerospace Times Company, located in Zhengzhou High-tech Development Zone, has developed and provided 60% electrical connectors and hundreds of electronic instruments for seven systems, including Shenzhou astronauts, applications, spacecraft, rockets, launch sites, measurement and control communications and landing sites. In the past 33 years, there has been no mistake in all previous space launches.
