The Shenzhou-11 spacecraft launched this morning consists of three parts: the orbital module, the return module and the propulsion module. China Aerospace Science and Technology Corporation Shanghai Aerospace Technology Research Institute in which the commitment to promote the cabin structure and assembly, power subsystem, docking system subsystem and a series of key development tasks. Compared with God Ten, Shenzhou 11 carried out a number of technical status changes, and according to the mission characteristics, to further strengthen the safety and reliability. Shenzhou spacecraft launch, at the moment the solar windsurfing open, the flight control center will certainly ring a warm applause. Solar panels are their source of energy for the technical equipment in spacecraft and astronauts' life support systems. The high-performance carbon fiber materials needed to make manned spacecraft solar panels have been relying on imports. In order to get rid of the controlled environment, Shanghai Aerospace and its counterparts work together to carry out the research and development of domestic products three years ago. Chen Cheng, deputy chief designer said that after repeated comparison and testing, they selected a high-modulus carbon fiber material developed by a domestic university: [The raw material itself has not been on the sky, we have done a lot of tests, such as resistance to atomic oxygen, charged with charged particles, as well as technology, used in various parts of the solar cell wing, how production performance. Also planned component-level test, the whole wing test, from mechanics, thermal aspects of more than a year to do the verification. ] The face of foreign technology blockade, feel the stones across the river, the designers have taken the road is not smooth. Unlike ordinary satellites, the Shenzhou-11 spacecraft will undergo a considerable degree of load during its orbital, docking and separation processes. In the beginning, the matching between new materials and the structural stability of some structures did not meet the requirements. After two years of tireless research, the final perfect solution to the problem. Chen Cheng said that this homemade "wing" of the Shenzhou-11 laid the foundation for the autonomous controllability of the space station project: [These conditions give the solar cell wing a very harsh load, the force will be relatively large, so the material should be strong enough, the stiffness should be good enough Caixing. The last product to be done to meet the mandate of the request, and even some aspects, than the performance of imported raw materials has improved. ] After two days of running on the orbit, the Shenzhou-11 will carry out an automatic rendezvous and docking with the Temple of Heaven II. Shanghai Aerospace docking institutions will once again be responsible for the realization of "space kiss" responsibility to ensure the safe operation of the assembly for 30 days. Jin Zongxiang, director of the docking institute research department revealed that they specifically verified the reliability of the docking mechanism for long time locking and separation after being sealed for the task. Facts have proved that 30 days is only a small target, for two years are safe: [Docking agencies have tightening, locking, maintaining action, it has a degradation mechanism. The general seal, pressure for a long time, pulled out will stick together. Before God eleven we also did some research on tackling the problem. When we were at 50 degrees above sea level, we would do 70 degrees and there would be a superposition factor. According to six months of curves and data to push, it can meet two years. ] Overall, the Shenzhou-11 relative to the former God IX, God 10, inheritance far greater than the improvement, indicating that China's heaven and Earth round-trip transport system maturity has been quite high. However, the same products, design and manufacturing processes as before seem a big difference. Yang Huaxing, chief designer of the Shenzhou-11 sub-division said that by tailoring the experience of the "old master" to processes and specifications, the company is tailor-made for group production and put into production. Higher quality management standards make space people more confident: [Analysis of the characteristics of these products, to develop a variety of control aspects. The risk of participation in people is also reduced to the lowest level. Why do we know with confidence that our product is no problem, this is a confident process of establishment. ] Above by the East Canton special correspondent Sun Ping, Meng Chengjie reported.
