Technology: breaking the hegemony that monopolizes the world

The wood is beautiful in the forest, and the wind will destroy it, not to mention that the current self is more than just excellent, and 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 R\u0026D department amid heated discussions among everyone.

At this time, other research and development departments in the entire Titan star park have not heard the news of the big boss's inspection.

Kyushu Technology has always been tighter on the outside and tighter on the inside. Many news have special review channels. Even Anhetang, which is the personal protection, cannot know Gu Qing's itinerary at any time.

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

In the spacious factory building, several robotic arms are hanging in the air for fishing construction, and there are robots patrolling the ground from time to time.

In each of the large drums and pipes, occasionally someone is seen welding construction and collecting data.

In addition, one research base after another is conducting "boring" tests.

In a research room, Gu Qing was "overhearing" 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 km/s, it can fly around the earth; if it reaches the second cosmic speed (11.2 km/s), it can escape the shackles of the earth; if it reaches At the third cosmic speed (16.7 km/s), it can fly farther into space.

The designer of our original launch vehicle transported the payload to orbit step by step through staged rockets in the order of "use-separation-abandonment".

However, in practice, it is found that during the jettisoning process, the rocket wreckage is out of control, which is very easy to cause secondary disasters, and even some wreckage will not fall to the ground, but enter orbit, causing potential harm to the entire orbit.

Therefore, the academic community has imagined whether the rocket can be recovered, which can not only avoid the problem of wreckage, but also reduce the investment of launch resources by using it again.

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

Take its first Earth-orbit mission, for example. More than 140 seconds after the rocket took off, the altitude was about 60 kilometers, and the speed had reached a very fast Mach 6 (Mach 1 is double the speed of sound).

At this time, its first sub-stage is shut down and separated from the second sub-stage, and then the engine nozzle faces the direction of the recovery point for a second ignition to reduce the flight speed.

When the flight altitude reaches about 70 kilometers, the grid wings on the first stage are opened. It has two functions, one is to use aerodynamics to decelerate, and the other is to control the attitude of the rocket. This is followed by a third firing, followed by a fourth firing near the touchdown point, which brings the speed down to 5 m/s and the landing cushion support legs open. Finally, and the most thrilling link --- falling vertically on the ground.

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

Because of the addition of the recovery step, the overall parameter optimization and design of the rocket has become more complicated, and at the same time, the accuracy control requirements for the entire vertical return have been greatly improved, and the landing buffer and propellant configuration are not ordinary. As simple as a rocket. "

Although the development of rockets is a difficult project, but from the old man's mouth, it seems like a trivial matter.

Gu Qing didn't bother this old professor who entered the teaching state. After all, he was snatched from a certain unit, and there is no problem with his professionalism.

"It's good for everyone to let the old men take a little bit of the younger generation when they go to the Titan Star Park to recuperate."

With some emotion, Gu Qing quietly left this area.

In the laboratory, the professor was still explaining incessantly.

"I have seen your design, in general, it is very mature, but when the rocket sub-stage is recovered, its carrying capacity will be greatly lost, not only the requirements for control components are high, but also the requirements for system software and materials are higher .

Especially the idea of ​​the interstellar transportation system, the direction is right, but the energy problem is still a long-standing problem..."

There is a sequence of hearing, and there is a specialization in the art industry.

For these old professors, Kyushu Technology hired them to give lectures, and did not expect these masters to really work hard and lead a team to tackle key scientific research problems. More I still hope that these old professors can cultivate a sufficiently righteous thinking and explain some of the general environment to young people who are new to the R\u0026D department.

No way, Jiuzhou Science and Technology's research and development strength in aerospace projects is really inferior to Guo Jia's team and some companies that are disguised as private companies, but are actually Guo Jia's team's company.

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

Bring these young engineers on the right track as soon as possible, and also be able to decentralize technology as soon as possible.

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

There are not only several open-air bases the size of football fields, but also an underground research and development base that has been dug up several floors by the Xia Jian 8th Bureau, as well as large-scale wind tunnels, nuclear test rooms, gunpowder testing and other field equipment.

This gold-swallowing beast has swallowed more than 10 billion funds of Kyushu 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, is currently leading a group of engineers to carry out research and development at a base tens 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 to form high-temperature expanded steam that is ejected to generate thrust.

Since the propellant directly flows through the nuclear fuel, debris particles will be peeled off under high temperature and high speed washing, causing the jet to pollute the environment with radioactive substances. There is no way to do this. "

"If the propellant is heated through a heat exchanger, although it can solve the problem of jet pollution, it will increase weight and reduce power, and ultimately its competitiveness may not be as good as chemical rockets."

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

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

"Onsa NASA's manned Mars missions basically use nuclear thermal rockets. They dare because they don't have the burden, but we can't."

"The thrust of the nuclear thermal rocket is actually inferior to that of the Long March solid rocket, but the jet speed is twice as fast, it can also save propellant, and it is easier to control."

Kyushu Science and Technology has cold nuclear fusion, but Gu Qing has been pinching it 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 in the mainland, but it will definitely make the current situation turbulent.

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

The rocket moves forward by the thrust generated by the rocket engine. During the movement, the engine continuously ejects high-speed gas flow outwards, and uses the reverse thrust of the gas flow to increase the speed of the rocket.

According to the operating principle of the rocket, the rocket project of the aerospace project is also divided into several major departments.

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

The Kyushu Aerospace Power Technology Research Department is responsible for the development of small solid motors and some explosives used in rockets and satellites;

The Kyushu Space Technology Research Department is responsible for the development of payloads carried by the rocket, including various communication satellites, such as Kyushu 6G project satellites, and manned spaceships under pre-research.

In addition, there is also the entire Titan Star project department and software system department that "do odd jobs" to produce supporting parts and send a professional team to develop the software control system needed for the entire aerospace project.

After inspecting the R\u0026D departments one by one, the sky was already dark.

Under the guard of Anhetang, Gu Qing returned to Jiuzhou Community, went to No. 1 cafeteria to have a barbecue, and then returned to his bedroom.

On June 3rd, Dong Qi rushed to the Kyushu Science and Technology Community with a look of excitement.

"They agreed! And they also relaxed the restrictions on the review of funds. 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 very flatly to express his understanding.

Because he understands this part of the people in Daxia very clearly. They only care about eating but not fighting. Only by moving out of the great god can they live a stable life.

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

In the financial market and the raw material market, such a big move cannot be concealed from people with good intentions, not to mention the massive operation of a star giant company, Suiren Company.

After various investigations and the frenzied exploration of domestic and foreign media and institutions, the news that Kyushu Science and Technology entered the aerospace industry, and Suiren followed up with the investment of trillions of Xiayuan, spread all over the world in just one hour.

At this time, a very strange phenomenon occurred. The media in Daxia basically quoted news and photo reports from foreign media. However, most of the foreign media reporters and organizations cited news and photo reports from Daxia media.

As for the interview video of the project parties?

not a single one!

Even some special metal companies that have been purchased in large quantities, when faced with the siege and interception of a crowd of media, they kept silent. A kind of panacea to resist.

If it is just an investment news of several trillion figures, everyone may think that it is a "picture cake" for Daxia enterprises to enter commercial aerospace projects.

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

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

"Great Xia Aerospace Engineering-Related Research and Development Institutions Have Made Large-Scale Personnel Changes"

"Special alloys, rocket propellants and other related industries have received hundreds of millions of investment"

"Suiren Company and Kyushu Science and Technology jointly took action to win a large piece of wasteland in the Xishu area"

"That man is not joking, Kyushu Technology seems to have a finished rocket"

These outrageous news one by one are like throwing bigger and bigger stones on a calm lake, stirring up the already unstable situation and making it even more volatile.

The discussion on the Internet about the joint venture of Kyushu Technology and Suiren is also very lively.

"What? I just started playing the qualifying match 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 big summer private companies spending trillions to enter the aerospace field, I feel that we may already be on the highway."

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

"From semiconductors to communication satellites, to aerospace projects, hold grass, Mr. Gu, you are my idol! YYDS!"

"I seem to see something. If Elon Musk is the spokesperson of certain forces of Uncle Sam, then Mr. Gu may also be the spokesperson launched by our relevant departments in Daxia. The difference between the two is that Gu always has R\u0026D strength, and Musk is a clown who engages in finance and fraud.”

"It's not advisable to hold and step on it. Gu Qing started out in a very strange way, and his connection with the fungus is too close. It is said that his confidentiality qualifications are all specially handled.

And Elon Musk also has real talents, don't belittle yourself. "

"No way, no way, these days, there is still this dog liar who monopolizes the family property, tricks his ex-wife into signing, and his son wants to sever ties. Starlink cuts off investors, Mars plans to cut off dreamers, and Dogecoin cuts off public dicks. ah?"

"Brother, you have too many buffs..."

"One thing to say, I still trust Mr. Gu. I have a classmate who works in Kyushu Technology. He said that he can often see Mr. Gu talking with R\u0026D personnel while eating in the cafeteria. Many unique insights often make these The R\u0026D personnel are emotional."

"WTF? Is this company going into aerospace? Come on, did they steal some core technology again?"

"Let Satan punish this thief."

"I hope that Gu in the far east can let us set foot on the moon in our lifetime. He and Elon Musk are heroes!"

I don't know whether Gu Qing's character design is too good, or the high-tech products of Kyushu Technology are deeply rooted in the hearts of the people. Netizens in the West and Daxia rarely directly criticize Gu Qing himself and Kyushu Technology's research and development capabilities.

However, in this heated public opinion, the West, especially Uncle Sam, was really stimulated.

The investigation into the joint action between Kyushu Science and Technology and Suiren Company, as well as the in-depth investigation into the research institutes and institutions related to Daxia's aerospace technology, the dollar bills were thrown like crazy.
