As beautiful as a tree is in the forest, the wind will destroy it. What's more, I am more than just excellent now. I don't know how many people want to eat me.

After conveying some of the company's future core business needs, Gu Qing left the bioengineering project research and development department amid heated discussions.

At this time, other R&D departments in the entire Titanium Park have not yet heard about the big boss’s inspection.

Jiuzhou Technology has always been tight on the outside and tight on the inside. Many news have special review channels. Even Anhetang, who is a personal protector, cannot know Gu Qing's schedule at any time.

Gu Qing's next stop was to the launch vehicle research and development department of the aerospace project.

In the spacious factory building, several robotic arms are suspended for fishing construction, and robots patrol the ground from time to time.

In the large barrel pipes, you will occasionally see people doing welding construction and collecting data.

In addition, there are research bases one after another conducting "boring" tests.

In a certain research room, Gu Qing was "eavesdropping" on a professor's lecture to new engineers.

"Actually, the principle of launching a rocket is the same as throwing a stone - the faster we throw it, the farther the stone will fall.

When the flight speed of the rocket exceeds the first cosmic speed, which is 7.9 kilometers/second, it can fly around the earth; if it reaches the second cosmic speed (11.2 kilometers/second), it can break away from the earth; if it reaches the second cosmic speed (11.2 kilometers/second), it can fly around the earth.

At the third cosmic speed (16.7 kilometers/second), you can fly farther into space.

The designers of our original launch vehicles used staged rockets to transport payloads to orbit one level at a time in the order of ‘use – separation – abandonment’.

However, in specific practice, it was found that during the abandonment process, the rocket debris was uncontrolled and could easily cause secondary disasters. Some debris would not even fall to the ground but enter the orbit, causing potential harm to the entire orbit.

Therefore, the academic community has wondered whether the rocket can be recovered to avoid the debris problem and to reuse it to reduce launch resource investment.

The Starlink project of the American Space Exploration Technology Company (SpaceX) relies on reusable rockets. What is the flight trajectory of SpaceX's rocket?

Take its first earth orbit mission as an example. More than 140 seconds after takeoff, the rocket was at an altitude of about 60 kilometers and its speed had reached a very fast Mach 6 (Mach 1 is one time the speed of sound).

At this time, its first stage shuts down and separates from the second stage. Then the engine nozzle is directed toward the recovery point and ignites a second time to reduce the flight speed.

When the flight altitude reaches about 70 kilometers, the grid wing on the first stage opens. It has two functions, one is to use aerodynamics to decelerate, and the other is to control the attitude of the rocket. Next is the third ignition, fast

When reaching the landing point, there is a fourth ignition, which reduces the speed to 5 meters/second, and the landing buffer support legs are opened. The last and most thrilling part is to fall vertically on the ground.

This process sounds simple, but SpaceX, which has mastered some of the technologies of the military-industrial complex and the aerospace group, has also failed in this project several times.

Because of the addition of the recovery step, the overall parameter optimization and design of the rocket have become more complicated. At the same time, the precision control requirements for the entire vertical return have increased a lot, there is also a landing buffer, and the propellant configuration is not ordinary.

As simple as a rocket."

Although the research and development of rockets is a difficult project, from the words of this old man, it seems like a trivial matter.

Gu Qing did not bother this old professor who was entering teaching mode. After all, he was a master who was snatched from a certain unit, and his professional quality was not a problem.

"When the old men go to the Titan Planet Park to recuperate, it will be good for everyone."

With some emotion, Gu Qing quietly left this area.

In the laboratory, the professor was still explaining endlessly.

"I have seen your design. Generally speaking, it is very mature. However, when the rocket sub-stage is recycled, its carrying capacity will be greatly lost. Not only does it have high requirements for control components, but it also has higher requirements for system software and materials.

.

Especially the idea of ​​an interstellar transportation system is in the right direction, but the energy issue is still a big problem..."

There is a sequence of learning, and there is a specialization in the arts.

For these old professors, Jiuzhou Technology hired them to give lectures, and they did not expect these experts to really work hard and lead teams in scientific research. More, they hoped that these old professors could train young people who have recently entered the R&D department.

A sufficiently righteous thought and an explanation of some of the general environment.

There is no way, Jiuzhou Technology's R&D strength in aerospace projects is really not as good as Guo Jia's team and some companies that pretend to be private companies, but are actually Guo Jia's team.

In the eyes of the young engineers who are new to the project, the seniors are also a hotter torch than ordinary celebrities and idols.

Putting these young engineers on the right track as soon as possible can also help them decentralize technology with peace of mind as soon as possible.

After leaving the training base for new engineers, Gu Qing drove for dozens of minutes and arrived at the most important core research and development area of ​​the entire aerospace project - the nuclear rocket research and development area.

There are not only open-air bases the size of several football fields, but also an underground R&D base dug several floors by the Xia Jian 8th Bureau, as well as large-scale wind tunnels, nuclear test chambers, gunpowder testing and other site equipment.

This gold-eating beast has already swallowed over 10 billion in funds from Jiuzhou Technology, and some of the equipment was obtained through resource exchange.

Zhan Zheng, the person in charge of the nuclear rocket research and development project, was leading a group of engineers to conduct research and development work at a base dozens of meters deep underground.

"Jet contamination and reliability are the key issues right now."

“The principle of a nuclear thermal rocket is to use a hot core to heat liquid hydrogen or water and other propellants into high-temperature expanded steam that is ejected to generate thrust.

Since the propellant flows directly through the nuclear fuel, debris particles will be peeled off under high temperature and high speed, causing the jet to contaminate the environment with radioactive materials. There is no way around it."

"If the propellant is heated through a heat exchanger, although it can solve the problem of jet pollution, it will increase the weight and reduce the power, which will ultimately make it less competitive than chemical rockets."

"Even if the problem of jet pollution is solved, we still need to consider the issue of rocket reliability, and even launch failure and explosion caused by man-made and non-man-made reasons.

Once a thermonuclear explosion occurs, a nuclear accident will make us all sinners, and nuclear pollution will even turn the accident area into a nuclear forbidden zone."

"NASA's manned Mars missions basically use nuclear thermal rockets. They dare because they can't afford it, but we can't."

"The thrust of the nuclear thermal rocket is actually no longer comparable to the Long March solid rocket, but the jet speed is twice as fast, it can save propellant, and it is easier to control."

Jiuzhou Technology has cold nuclear fusion, but Gu Qing has been holding it back and not taking it out.

Because he knows that once this thing is taken out, it will inevitably trigger a new war. Maybe the war will not be at home, but it will definitely make the current situation turbulent.

Therefore, even today, he has not opened up the real core technical authority of the aerospace project.

The rocket relies on the thrust generated by the rocket engine to move forward. During the movement, the engine continuously sprays out high-speed gas flow, and uses the reverse thrust of the gas flow to increase the speed of the rocket.

According to the operating principles of rockets, rocket projects in aerospace projects are also divided into several major departments.

Jiuzhou Launch Vehicle Technology Research Department is responsible for the development and production of rocket bodies and engine production;

Jiuzhou Aerospace Power Technology Research Department is responsible for the development of small solid motors and some pyrotechnics used on rockets and satellites;

Kyushu Space Technology Research Department is responsible for developing payloads carried by rockets, including various communication satellites, such as Kyushu 6g project satellites, and manned spacecraft that are under pre-development.

In addition, there are "part-time" Titan project departments and software system departments that produce supporting parts and send professional teams to develop the software control systems needed for the entire aerospace project.

After inspecting each R&D department, it was already dark.

Under the protection of Anhetang, Gu Qing returned to Jiuzhou Community, went to Canteen No. 1 for a barbecue, and then returned to his bedroom.

On June 3rd, Dong Qi rushed to the Jiuzhou Technology Community with an excited face.

"They agreed! And they also relaxed the restrictions on payment review. We only need to verify the list with the relevant core confidential departments. The board of directors cannot easily intervene in other fund flows and project control!"

Facing the excited Dong Qi, Gu Qing nodded calmly to show his understanding.

Because he has a clear understanding of this part of the people in Daxia. They care about food and not about fighting. Only by moving out of the Great God can they live a stable life.

Subsequently, Suiren Company began to mobilize a large amount of funds and resources.

In the financial market and raw material market, such a big move cannot be hidden from those who are interested, let alone the large-scale operation of Suiren Company, a star giant.

After multiple investigations and frantic exploration by domestic and foreign media and institutions, the news that Jiuzhou Technology entered the aerospace industry and that Suiren Company followed suit with an investment of several trillion Xia Yuan spread around the world in just one hour.

A very strange phenomenon occurred at this time. The media in Daxia basically quoted news and photo reports from foreign media. However, foreign media reporters and institutions quoted mostly news and photo reports from Daxia media.

As for the interview video with project parties?

not a single one!

Even some special metal companies that were purchased in large quantities kept silent when faced with the media's pursuit and interception. They were really blocked and had no choice but to say "the company's confidential business cannot be disclosed to the outside world at will."

Use the magic oil of words to resist.

If it were just an investment news with a figure of several trillion, everyone might think it was a "picture" for Daxia Enterprises to enter commercial aerospace projects.

But as the investigation deepened, countless media people felt a kind of frightening trembling.

"Graduates and current students majoring in aerospace engineering related majors in Daxia received mysterious offers"

"Daxia Aerospace Engineering-related R&D institutions have made large-scale personnel changes"

"Special alloys, rocket propellant and other related industries receive hundreds of millions of investments"

"Suiren Company and Jiuzhou Technology jointly took over large areas of wasteland in the Western Shu region"

"That man is not joking, Jiuzhou Technology is suspected to have a finished rocket"

Each of these more outrageous news is like throwing a bigger stone on a calm lake, stirring up the already unstable situation and making it even more volatile.

Discussions on the Internet about this joint venture between Jiuzhou Technology and Suiren Company are also very heated.

"What? I just started playing the ranked matches of "Omnic Crisis", and Gu Qing is planning to fly in the blink of an eye?"

"Witnessing history, from creating starch out of thin air to private companies spending trillions to enter the aerospace field, I feel that we may already be on the highway."

"I heard a while ago that Jiuzhou Technology has placed a lot of orders for several large launch sites across the country. The communication on WeChat is like setting off fireworks. Basically, there are a lot of them going to the sky every week. Jiuzhou Technology is really awesome.

…”

"From semiconductors to communication satellites to aerospace projects, Zhicao, Mr. Gu, you are my idol! yyds!"

"I seem to see something. If Elon Musk is the spokesperson of some forces in Uncle Sam, then Mr. Gu may also be the spokesperson launched by our relevant departments in Daxia. The difference between the two is that Mr. Gu has

He has strong research and development capabilities, but Musk is just a clown who engages in finance and fraud."
