Traveling through the sword to engage in military industry.

The matter of ocean shipping piracy came to an end.

After returning to the front line of scientific research, Ren Zhong received a very surprising news.

"Mr. Ren, I have an exciting news for you! After our team's hard work day and night, the first generation of manned spacecraft has finally been successfully built. All current ground tests have shown excellent performance and all indicators are normal. According to the established plan, one month later, we will usher in a historic moment - the first launch and recovery test of a manned spacecraft. However, for safety reasons, we have decided to use animals as passengers for the first test, specifically a strictly trained monkey. It will serve as our 'space ambassador' and will be the first to experience the mysteries of the universe." Professor Qian, the head of the Aerospace Research Center, could not hide his excitement and pride in his voice, which was conveyed to Ren Zhong through the telephone line.

Ren Zhong's hand holding the phone trembled slightly, and his joy was beyond words. "Professor Qian, this is simply great! This is undoubtedly the most exciting news for me today. Please allow me to make some arrangements. I can't wait to go there in person and witness this historic moment with my own eyes." Ren Zhong's voice was full of infinite longing for the first generation of manned spacecraft. Even in the main world, Ren Zhong did not have such an opportunity to see a spacecraft up close.

What's more, this is another historical milestone and great achievement that was successfully researched under his personal arrangement.

In fact, according to the history of the main world, the first manned space flight of mankind took place in 1961. At this moment, they are standing on the edge of this great feat, and they are even expected to realize this dream ahead of time. In the past few years, in order to seize the initiative in space exploration and win the unparalleled honor of being the "first human to step into space", after completing the launch mission of the low-Earth orbit satellite to build a long-distance communication network, Dongda has set its sights on the more distant universe to prepare to launch synchronous satellites, and on the other hand, it is developing manned space flight! Sending people into space.

As early as 1956, the Space Research Center proactively adjusted its research direction, conducting research and launching synchronous orbit communication satellites with wider applications and longer lifespans.

At the same time, the development of the third-generation heavy-load rocket, the Long March 2F, and the secret development of the manned spacecraft that goes with it began in terms of transportation. This is an unprecedented challenge that requires overcoming numerous technical difficulties, from material science to life support systems, from aerospace medicine to emergency escape systems, each of which is a test of human wisdom to the extreme.

As a science and technology prophet, Ren Zhong knows that the success of this manned spacecraft not only means a major breakthrough in the field of aerospace for Dongda, but also an important step for human beings to explore the universe and pursue the unknown. Therefore, he can't wait to witness this moment with his own eyes, share this glory and joy with the team, and jointly open a new chapter in human exploration of the universe.

Although the carrying capacity of the Long March 2F carrier rocket is reduced compared to the main world, and its total weight has not yet reached the threshold of 300 tons, this does not mean that its achievements are insignificant. On the contrary, through countless precise calculations and optimizations by the project team, the current Long March 2F has the ability to safely send satellites or spacecraft weighing up to 5 tons into low-Earth orbit, which is undoubtedly an achievement to be proud of.

At the Space Technology Research Center of Dongda University in the Sword World, this historic step of human beings conquering space is being given unprecedented significance. Thanks to the space rocket design data that Ren Zhong carefully brought back from the main world, Dongda University has quietly led its competitors in the Sword World in the field of heavy-load rocket research for at least three years. This lead is not only a technological leap, but also a firm practice of the human dream of exploring the universe.

However, the technological lead is not unshakable. The two major forces, Big Bear and Rogue Eagle, have deeply realized the strategic position of space in the future development of mankind, and are accelerating their pursuit at all costs. From satellite launches to intercontinental missiles, their research centers are catching up with the pace of Dongda in all aspects and angles. With the advantage of talents widely collected in the world of Liangjian, the research teams of these two competitors have far exceeded the scale of Dongda Space Research Center, forming a strong competitive pressure.

Faced with such challenges, the Space Research Center of the University of Science and Technology has shown extraordinary tenacity and wisdom. On the one hand, they actively recalled elite students studying abroad, and on the other hand, relying on the careful guidance of the older generation of scientists, they selected and trained batches of young and promising aerospace talents from the university. After more than ten years of unremitting efforts, the ten disciples personally trained by Professor Qian have grown into leaders of their respective teams. They are responsible for rocket research, satellite research, and first-generation spacecraft research and other key fields, and together support the aerospace industry of the University of Science and Technology.

In order to seize the honor of being the first human to land in space, Ren Zhong found the most easily accessible manned spacecraft design data in the main world - the main design of the Vostok spacecraft that has now been declassified. This is a spacecraft that has successfully achieved manned flight. No matter how many shortcomings it has from the perspective of the main world, it is currently the easiest to design successfully according to this design data.

Ren Zhong also wanted to build the Shenzhou series of spacecraft in one go, but unfortunately, there was no way for him to get the information now!
Moreover, according to some public information studied by Ren Zhong, the design and materials of the Shenzhou series are still too difficult for the current stage of the Bright Sword world.

You have to know that the technology level of Shenzhou 90 is at the end of the s, and the current basic technical conditions in the world of Bright Sword are not yet able to be that advanced.

Ren Zhong spent hundreds of thousands of dollars and bought the design drawings of the Vostok spacecraft and the Vostok carrier rocket from the old papers in the Daming Archives through underground channels. He made a digital version and brought it to the ninth district of the Bright Sword World to reprint it and gave it to Professor Qian and others for reference.

Unexpectedly, only two years later, Ren Zhong received good news.

District 9, Xishan.

A branch of the Aerospace Technology Research Center is located here, and all manned spacecraft projects are implemented here. There are dozens of factories of all sizes hidden in the factories located among the rolling mountains, and some core factories are even built inside the mountains.

Of course, Ren Zhong did not need to go to these factories to check the production of parts. He went directly to the final assembly and test plant of the manned spacecraft project.

"Mr. Ren, we have fulfilled our mission. Our first generation manned spacecraft Shuguang-1 has finally been successfully developed." Professor Qian smiled as he greeted Ren Zhong at the gate of the test factory. "We have made some improvements based on Mr. Ren's design. We have enlarged the spherical sealed cabin to make it more like an elliptical cylinder. We have appropriately reduced the cylindrical instrument cabin. According to the current number and size of space measurement instruments, we do not need as much space as originally designed. The improved Shuguang-1 can now theoretically carry two people into space.

Although the number of passengers has been increased, the total weight after the change is more than 100 kilograms less than the original design. Even with the weight of one more person, the total weight of the empty spacecraft is actually less. We can balance the total weight by loading some space observation equipment into the spacecraft. In theory, the risk of using the original design of the launch vehicle is minimal. "Professor Qian led Ren Zhong into the spacious factory and pointed to the spacecraft not far away.

Ren Zhong carefully observed the world's first spacecraft and found that there had indeed been significant changes compared to the design data he had provided. The original spherical cabin had a diameter of 2.3 meters, which was a bit cramped for one astronaut. It has now been modified to become more elliptical, with the longer end of the ellipse being 1 meters. The two relative cabins are now designed to have larger spaces and are more friendly to astronauts.

In comparison, the instrument cabin, which was originally connected to the last-stage carrier rocket and was more than 5 meters long, was shortened a bit, but the overall length was still maintained at about 7.35 meters, ensuring that the overall aerodynamic design is better than the original design. In addition, a large amount of new materials that had not been invented in the original time and space, such as carbon fiber, were used, and the weight of the Dawn- spacecraft was significantly reduced. The reduced weight allowed Professor Qian and his team to add more safety precautions to the first-generation spacecraft, providing better conditions for resisting various radiation in space.

Otherwise, even if Ren Zhong brought back the Vostok spacecraft data from the main world, this initial version had many inherent defects, and if it was copied completely, it would cause great harm to the astronauts.

Therefore, Professor Qian and his team did not completely copy the original design. Instead, they made substantial improvements in protection based on some space radiation values ​​provided by Ren Zhong, especially in the design of astronauts' space suits. This part also adopted the design standards and concepts of the new generation of space suits from the main world brought back by Ren Zhong, mainly to improve the safety of astronauts. Considering that the new launch rocket has a greater carrying capacity than the original rocket, the added weight is theoretically not a big problem.

Next, we will basically make major changes to the layer of heat-proof material covering the outer surface of the cabin. Now Ren Zhong has brought heat-proof materials from the main world to the space center. Compared with the heat-proof materials used in the early manned spacecraft in the main world, the use of new heat-proof materials will make the spacecraft safer when returning to Earth.

However, the life support system in the spacecraft cabin is a bit difficult to deal with. There is not much reliable information in this regard. Ren Zhong spent a lot of money to dig up some not-so-confidential information. Then Professor Qian and his team designed a new life support system based on this information. After a large number of tests, it was confirmed that the life support system is indeed much stronger than the original design.

The spacecraft is now equipped with a life support system that can sustain 15 days and nights of flight for two pilots. The redundancy of the entire system has been greatly enhanced. Next, corresponding improvements have been made to the ejection seat and radio, optical, navigation and other instruments and equipment. With the new technology that Ren Zhong brought from the main world, these things can be completely replaced by more advanced technology now, which will further improve performance and greatly reduce weight. In particular, the current radio technology is more than two generations stronger than the original design of Vostok.

The current Shuguang-7 spacecraft is designed to jettison the final stage of the launch vehicle and the instrument cabin before returning, and the manned cabin will re-enter the atmosphere alone. When the cabin descends to an altitude of about kilometers from the ground, the astronauts will eject the cabin and then land alone with a parachute. This landing method is quite different from the later method of returning to the ground directly in the space cabin in the main world.

The instrument cabin of the spacecraft is located behind the cockpit, and is equipped with chemical batteries, return thrust rockets and other auxiliary equipment. After the spacecraft is launched into space, it can be controlled automatically or manually by astronauts. According to the design specifications and under normal flight conditions, the perigee of the Shuguang-180 spacecraft flight orbit is about 222 kilometers, the apogee is 327-65 kilometers, the inclination is about 89 degrees, and one cycle around the earth is about minutes.

In other words, it takes 89 minutes for the Dawn- spacecraft to travel around the earth!

It’s a bit like spending one hour in heaven and one day on earth!

"Well, Professor Qian, you have done a great job. After the Dawn-1 that we are testing now, how long will it take for the Dawn-2 and Dawn-3 to be ready?" Ren Zhong asked.

"Mr. Ren, this time we still use the modular design mode and have prepared 5 sets of components for the Shuguang-2 manned spacecraft. We are going to complete at least 2 unmanned flight tests this year. If everything goes well, after unmanned flight tests next year, we will use manned space flight for the fifth time. As for whether the fifth flight will be held during the National Day or New Year's Day next year, we still need to evaluate the results of the first four unmanned flight tests before we decide."

Professor Qian said that they had great trust in the information provided by Ren Zhong, so when designing and producing, they did not hesitate to design one set, but directly made five sets according to the test plan!

Some components may undergo certain adjustments and optimizations, but based on past experience, there is not much room for optimization, so there is not much pressure to produce five sets at one time.

Now Ren is racing against time to realize the world's first astronaut landing plan at the University of Tokyo. In terms of R&D costs, they are almost unlimited in meeting the requirements put forward by the project team.

According to the plan, starting with the Dawn-1 spacecraft, animals will be carried to simulate humans. Although there are some differences in body shape from humans in details, through means such as counterweighting, it is ensured that the weight is almost the same as that of astronauts, so that the performance and stability of related systems can be fully tested.

After watching all the test items on the ground, Ren Zhong was confident in the improved version of the Shuguang-1 spacecraft developed by Professor Qian and his team, and quickly approved the first launch! (End of this chapter)
