"Bad thing!" LU Hong, head of the space agency and the spacecraft Research Institute, had a headache.

    The timing of the incident of this law is too fatal for the Americans. They have long been used to the ban on aerospace materials and technology.

    However, those experts and scientific research teams occupy an important position in the research and development of the Tiangong space station. Once the cooperation is stopped, some projects will be forced to be suspended.

    For a time, it is difficult to find alternative candidates and schemes.

    "The progress can''t be stopped!" his deputy said anxiously. "Originally, according to the plan, we would launch the three space modules of Tiangong this year. If we miss the time, it will affect our overall strategy!"

    The project of Tiangong space station has been determined since the americans refused to join the international space station!

    After so many years, Huaxia space agency has been preparing silently. They want to send the Tiangong space station to heaven before the International Space Station retires!

    In this way, only Chinese people in space will have the space station. If other countries want to conduct space research, they must make friends with China and pay certain benefits to enter. At that time, we can take this opportunity to tear a hole in the blockade of the international aerospace industry!

    But now, the plan was suddenly disrupted.

    They can also design the Tiangong space station given time, but now the situation changes. They are worried that before the Tiangong is fully completed, the Americans launched a new space station... Even if they launched the Tiangong at that time, it will not be as effective as it is now.

    "Why don''t you ask the brother department for help?" the Deputy suggested.

    "Please who?" as soon as Lu Hong spoke, he knew what his deputy thought. "You mean, Du Xingyu?"

    "Yes, that''s him! He led the design of the last aerospace plane. Lao Zhang worked with him. When he came back, he said, how powerful Du Xingyu is!"

    "If you let Du Xingyu come, maybe you can catch up with the progress," said the deputy.

    "Du Xingyu... OK, let me talk to the rocket research institute." LU Hong nodded.

    Soon, Du Xingyu received the news and asked him to help at the Tiangong space station.

    Du Xingyu was thinking about the space station. When he heard the news, he promised, brought the information and went to the spacecraft Research Institute.

    "Dr. Du, you''ll have to work hard next!" LU Hong is a thin old man, born as a scholar and dressed very plainly.

    "I can''t talk about hard work," said Du Xingyu. "President Lu, I have a request. I hope you can pay attention to the improvement plan I put forward."

    "Of course, everyone wants to make Tiangong better! This will be China''s first base in space!" LU Hong promised, and he gave Du Xingyu great authority. "You can let go, I''ve told you, and let the team cooperate with you to the greatest extent!"

    Du Xingyu officially settled in the R & D team of Tiangong space station. The leader of the team is Xiong Ming, an old professor of space physics and one of the academicians of the National Academy of engineering.

    Xiong Ming and his teacher Liu Yuan are old friends. According to their seniority, they are Du Xingyu''s martial uncle.

    "We launched the Tiangong-1 target aircraft in 2011. Three astronauts of shenzhou-9 entered Tiangong-1; later, a female astronaut also entered."

    "In 2016, we launched tiangong-2 space laboratory."

    "These two are the water test production of Tiangong space station. The real Tiangong space station should be a large space station composed of multiple space modules." the people of the project team are introducing Du Xingyu to the current research situation of the space station.

    "We initially intend to launch three 60 ton space station modules, especially after the emergence of the nuclear powered rocket XingKong II, the launch conditions have been basically met. Even in the manufacturing of the space station, there are problems... You know, several foreign experts are limited, and it is difficult to overcome some difficulties for a time..."

    Du Xingyu looked at the project carefully and studied the Tiangong space station module that had been manufactured.

    After several days of analysis, he said: "if it''s my idea, the three 60 ton space stations should be improved. They can be changed to 100 tons and add more functions!"

    "100 tons? Is it OK?" some experts wondered.

    "Of course it can. The long march rocket has not enough carrying capacity, and there are nuclear powered rockets," Du Xingyu said.

    "The cost of transformation is too high!" someone commented, "it will make us exceed our budget!"

    "Apply for more budget." Du Xingyu vowed, "I''m sure the added quality and functions will definitely be worth the money! The current cost is for more convenience in the future!"

    "Our heavenly palace will not only surpass the current international space station, but also serve as a base station for landing in space and a space transportation center between the moon and the earth in the future."

    "So now when designing, we need to add many functions and parts... Three space modules are not enough. We can add more modules later. But now, I suggest directly modifying the scheme trunk to prepare for the future."

    "Do you think so?" Xiong Ming asked.

    "Yes, in fact, I have a preliminary transformation plan!" Du Xingyu''s direct space station simulation is not done in vain.

    In recent days, according to the actual situation of Tiangong and the project team, he made design modifications.

    Build the most advanced space station in the world based on Tiangong!

    Du Xingyu put out the plan and began to explain it to the public.

    At the beginning, some people still didn''t understand it, but after listening, they found that Du Xingyu didn''t talk casually, but took it seriously with perfect design ideas and ideas.

    Du Xingyu talked about his plan for three days, and then Xiong Ming and others demonstrated it for two days.

    "Xiao Du, we all agree that your idea is excellent, ten times stronger than our previous design idea!" Xiong Ming said with emotion, "just follow what you said, Tiangong, make great changes!"

    The word "change!" enabled the Tiangong R & D team to work with high intensity.

    The overall design idea should be modified. It should not be limited to the small space station at the beginning, but be designed and manufactured as an expandable large and medium-sized space station.

    The modular design allows the space station not to design so many modules at the beginning, and then supplement them slowly.

    First of all, we must design the necessary modules such as life module, plant module, medical module and power module!

    Du Xingyu has lit up every module on the technology simulator. He personally participated in the design of the module and gave inspiration and inspiration to the team.

    Two weeks later, the first module has been modified.

    "The life module is a space module to maintain the life of astronauts. It has a complete water circulation and air circulation system, and the generated space waste can also be treated in this module." it is much faster to modify it on the basis of the original module than to directly manufacture it.

    "With an initial mass of 104 tons and multiple space connections, this life space module can provide ten astronauts with enough resources to live in space for a whole year!"
