Chapter 735 Kyushu Aerospace Project (4k)

A tree that stands out in the forest will be destroyed by the wind. Moreover, I am more than just outstanding 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 R&D department amid the heated discussion of the crowd.

At this time, other R&D departments in the entire Titanium Star Park have not yet known the news that the big boss is coming to inspect.

Jiuzhou Technology has always been tight outside and tighter inside. Many messages have special review channels. Even An Hetang, who is a close protector, cannot know Gu Qing’s schedule at any time.

Gu Qing’s next stop is the launch vehicle R&D department of the aerospace project.

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

In large barrels and pipes, you can occasionally see people welding and collecting data.

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

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

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

When the rocket's flight speed 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 break away from the earth; if it reaches the third cosmic speed (16.7 km/s), it can fly to farther space.

The designers of our original launch vehicle used a staged rocket in the order of 'use-separation-discard' to transport the payload to orbit one level at a time.

But It was discovered in actual practice that during the abandonment process, rocket debris is out of control and can easily cause secondary disasters. Some debris may not fall to the ground but enter orbit, causing potential harm to the entire orbit.

So the academic community has imagined whether it is possible to retrieve the rocket, which can not only avoid the debris problem, but also be reused to reduce the investment in launch resources.

The Starlink project of the Space Exploration Technology Company (SpaceX) of the United States 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 the rocket took off, When the altitude is about 60 kilometers, the speed has reached a very fast Mach 6 (1 Mach is one times the speed of sound).

At this time, its first stage is shut down and separated from the second stage. Then the engine nozzle is ignited for the second time in the direction of the recovery point 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 slow down, and the other is to control the attitude of the rocket. Next is the third ignition, and there is a fourth ignition when it is close to the landing point, which reduces the speed to 5 meters/second, and the landing cushion support legs are opened. Finally, it is also The most thrilling part is vertical landing on the ground.

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

Because of the addition of the recovery step, the overall parameter optimization and design of the rocket have become more complicated, and at the same time, the accuracy control requirements for the entire vertical return have been greatly improved. The configuration of landing cushion and propellant is not as simple as that of ordinary rockets. "

Although the development of rockets is a difficult project, it sounds like a trivial matter when it comes from the mouth of this old man.

Gu Qing did not bother the old professor who was in the teaching state. After all, he was a big shot who was snatched from a certain unit, and his professional quality was still no problem.

"Let the old men take care of the younger generation when they go to the Titanium Star Park for recuperation. It will be good for everyone."

With some emotion, Gu Qing left the area quietly.

In the laboratory, the professor was still explaining incessantly.

"I have seen your design. Generally speaking, it is very mature. However, when the rocket substage is recovered, its carrying capacity is greatly lost. It not only has high requirements for control components, but also has higher requirements for system software and materials.

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

There is a sequence in learning, and there are specialties in skills.

For these old professors, Jiuzhou Technology hired them to give lectures, and did not expect these masters to really work hard and lead the team to tackle scientific research. More importantly, it hopes that these old professors can cultivate a sufficiently correct mindset for the young people who have just entered the R&D department, as well as some explanations 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 are disguised as private enterprises, but are actually Guo Jia's team.

In the eyes of young engineers who have just entered the project, the old predecessors are also torches that are hotter than ordinary star idols.

Bringing these young engineers on the right track as soon as possible can also relieve the technology as soon as possible.

After leaving the base for new engineer training, Gu Qing took a car for dozens of minutes and arrived at the most important core R&D area of ​​the entire aerospace project - the nuclear rocket R&D area.

There are not only open-air bases as big as several football fields, but also underground R&D bases dug several layers by Xia Jian 8th Bureau, as well as large wind tunnels, nuclear test laboratories, gunpowder testing and other site equipment.

This money-eating beast has swallowed up more than 10 billion yuan of Jiuzhou Technology’s funds, and some of the equipment was obtained through resource exchanges.

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

"Jet pollution and reliability are the key issues at present."

"The principle of nuclear thermal rockets is to use the hot core to heat liquid hydrogen or water propellants into high-temperature expanded steam and eject it to generate thrust.

Since the propellant flows directly through the nuclear fuel, the high-temperature and high-speed scouring will peel off the debris particles, causing the jet to carry radioactive substances and pollute the environment. There is no way to solve this problem."

"If the propellant is heated by a heat exchanger, although the jet pollution problem can be solved, it will increase the weight and reduce the power, and ultimately its competitiveness may be inferior to that of chemical rockets."

"Even if the jet pollution problem is solved, we still need to consider the reliability of the rocket, and 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 the nuclear pollution will make the accident area a nuclear restricted area."

"NASA's manned Mars mission basically uses nuclear thermal rockets. They dare to do it because they have no burden, but we can't."

"The thrust of nuclear thermal rockets is actually not as good as that of 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 and not taking it out.

Because he knew that once this thing was taken out, it would inevitably trigger a new war. Perhaps the war would not be on the homeland, but it would definitely make the situation turbulent.

Therefore, even to this day, he has not opened up the truly core technical permissions of the aerospace project.

The rocket relies on the thrust generated by the rocket engine to move forward. During the movement, the engine continuously ejects high-speed gas flow outward, using 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 Jiuzhou Launch Vehicle Technology Research Department is responsible for the development and production of the rocket body and engine production;

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

The Jiuzhou Space Technology Research Department is responsible for the development of the payload carried by the rocket, including various communication satellites, such as the Jiuzhou 6G project satellite, and the manned spacecraft that is being pre-researched.

In addition, there is the entire Titanium Star Project Department and the Software System Department, which "do odd jobs", producing supporting parts and sending professional teams to develop the software control system needed for the entire aerospace project.

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

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

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

"They agreed! And they also relaxed the restrictions on the audit 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 calmly to show his understanding.

Because he saw this part of Daxia very clearly, remembering to eat but not to be beaten, only by moving out the gods can they live a stable life.

Then 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 those who are interested, let alone the big operation of Suiren Company, a star giant enterprise.

Under multiple investigations, the crazy exploration of domestic and foreign media and institutions, Jiuzhou Technology entered the aerospace track, and the news that Suiren Company followed up with 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 news and photo reports quoted by foreign media reporters and institutions were from Daxia media.

As for the interview videos of the project parties?

None!

Even some special metal companies that were purchased in large quantities kept silent when facing the pursuit and blockade of a group of media. They were really blocked and could only use the panacea of ​​"company confidential business, which cannot be disclosed to the outside world at will."

If it was just a news of investment of trillions of dollars, everyone might think it was a "pie in the sky" for Daxia enterprises to enter the commercial aerospace project.

But as the investigation deepened, countless media people felt a tremor of fear.

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

"R&D institutions related to aerospace engineering in Daxia have undergone large-scale personnel changes"

"Special alloys, rocket propellants and other related industries have received billions of dollars in investment"

"Suiren Company and Jiuzhou Technology have joined forces to acquire a large area of ​​wasteland in the Western Shu region"

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

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

The discussion on the Internet about the joint big move by Jiuzhou Technology and Suiren Company is also very heated.

"What? I just started playing the qualifying match of "Smart Machine 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 enterprises in Daxia spending trillions to enter the aerospace field, I feel like we may already be on the expressway."

"I heard a while ago that Jiuzhou Technology has placed quite a few orders for several major launch sites across our country. The WeChat communication is like setting off fireworks. Basically, there are a lot of launches every week. Jiuzhou Technology is really fucking generous..."

"From semiconductors to communication satellites, and then to aerospace projects, damn, Mr. Gu, you are my idol! YYDS!"

"I seem to have seen something. If Elon Musk is the spokesperson for some forces of Uncle Sam, then Mr. Gu may also be the spokesperson pushed out by the relevant departments of our Daxia. The difference between the two is that Mr. Gu has R&D capabilities, while Musk is just a clown who engages in finance and fraud."

"It is not advisable to praise one and step on the other. Gu Qing's start-up was also very strange, and his connection with Junfang was too close. It is said that his confidentiality qualifications were specially handled.

And Elon Musk is also a real talent, don't belittle yourself."

"No way, no way, these days there are still lickers who embezzle the family property, trick his ex-wife into signing, and his son wants to cut off relations. Starlink cuts investors, Mars Project cuts dreamers, and Dogecoin cuts the general public."

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

"To be honest, I still trust Mr. Gu. I have a classmate who works at Jiuzhou Technology. He said that he often sees Mr. Gu talking with R&D personnel while eating in the cafeteria. Many unique insights often make these R&D personnel sigh."

"WTF? This company is going to enter the aerospace field? Please, have they stolen some core technology again?"

"Let Satan punish this thief."

"I hope that Gu from 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 personality is too good or Jiuzhou Technology's high-tech products are deeply rooted in the hearts of the people. Netizens in the West and Daxia rarely directly criticize Gu Qing himself and Jiuzhou Technology's R&D strength.

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

The investigation of the joint action of Jiuzhou Technology and Suiren Company, as well as the in-depth investigation of the research institutes and institutions related to Daxia aerospace technology, the US dollars were thrown away like crazy.
