Super military empire

"Is there a person named Guo Wanjun in the Dongfeng-31 project?" Liu Yijiu wanted to talk about this before, but every time he talked to his lips, then he couldn't remember it for a while, this time it was completely remembered. Up.

Many technical details of the Dongfeng-31 project were leaked, which eventually led to the overall acceleration of the deployment of Dongfeng-41.

Even foreign countries know this kind of project because of the existence of this product.

"What's wrong? I haven't heard of this name. Do you want to dig someone from our side again?" Old Qian heard Liu Yijiu asking someone, and immediately became alert.

If Liu Yijiu wants to dig people, he must first understand them clearly.

"You kid said, you can't come to us to dig people anymore. Even Lao Liang and the others are on your side. Although they don’t belong to your Ninth Institute, the relationship is with our aerospace, but they are all working on your projects. What about the service...If you dig people again, it wouldn't be appropriate..." Qian Lao saw Liu Yijiu's mouth twitching, as if some conspiracy had been exposed by him, and he was immediately dissatisfied.

This kid is too much.

Seeing that he was about to set off for the Jiuquan Satellite Launch Base, Liu Yijiu didn't say much, just deal with such things when he was ready to return.

Such a major spy case affects the interests of the entire country.

"Wait until you come back."

Along the way, Qian always made people watch Liu Yijiu very closely, and he was not allowed to inquire about the middle-aged technical backbone in aerospace.

The Ninth Academy also has a missile project, which is obviously a project to grab space.

They are engaged in the two projects that were forced to discontinue the Dongfeng-6 and Dongfeng-7, which are not very conflicting with the current projects of the aerospace industry. At the same time, the technology invested and acquired by the Ninth Institute is a good thing for the entire aerospace industry. Technology can be used directly.

There are advantages, but the disadvantages are equally obvious.

The domestic personnel training in this area simply can't keep up, especially the experienced middle-level technical backbone, the people of the Ninth Academy, obviously can't wait.

Digging people is the basis of their development.

Liu Yijiu must be prevented from digging the corner of space.

For this purpose, the Ministry of Aerospace Industry even made arrangements for Liang Sili and Ren Xinmin to bring a large technical team into the Dabashan Base of the Ninth Academy.

"I said, Dad Qian, let's be a family anyway. You guard me like a thief, isn't it?" Liu Yijiu originally wanted to understand the situation through their people, but he didn't expect it. Satellite launch bases are staring at themselves.

This is really unpleasant.

"Do you still know that you are a family? The people in the aerospace industry are already nervous. There is a pit for each radish, and there are even many pits waiting for the radish..." The old man did not buy this boy's account.

It's too much understanding.

"I really don't want to dig people. Forget it, wait until after the launch!" Liu Yijiu was also helpless.

If I say that Guo Wanjun has been bought by Taiwanese spy Woweihan to sell some technical information of Dongfeng-31, this may not even convince Qian Lao and others.

Liu Yijiu has no evidence!

What I know is only based on history.

Is the history of this world still the same as before?

No one knows.

"As long as you don't dig people, it's easy to say. Do I say you are? Our two technologies are common..."

Old Qian was delighted when Liu Yijiu said that he would not dig people.

"Now that the rocket sub-levels have started the erection and docking before launch, don't you plan to check it out?"

"Look! Even though I have seen it on the drawings and even the production process, I have not seen the launch yet!" Liu Yijiu was telling the truth.

He had seen the spectacular launch of satellites in video recordings countless times before, but he had never visited it at all.

The Long March 3 Type A rocket has a total length that exceeds history. It is docked with a satellite, plus a fairing, and the length has reached 55 meters.In other words, the entire length is almost 20 stories tall!

This thing is so spectacular, it is absolutely impossible to have such a deep feeling without standing in front of it.

Even, when seeing the spectacular things built by human beings are assembled like building blocks one by one, the kind of shock in the heart can never be experienced without going to the scene.

"We saw this thing assembling it with our own eyes. You can't see it at a glance! Old Qian, how spectacular do you think the Soviet Union thing with a thrust of thousands of tons?" But Liu Yijiu thought of the Soviet Union’s super rockets that no one had surpassed in the world for many years.

The "Energy" carrier rocket is about 60 meters long, has a total weight of 2,400 tons, and has a takeoff thrust of 3,500 tons. It can send a 100-ton payload to low-Earth orbit.This kind of rocket, for nearly a hundred years after its appearance, has always maintained the title of the rocket with the largest takeoff mass and thrust in the world.

It is precisely because of this thing that the Soviet Union first established the Mir International Space Station on Earth orbit, and carried laser weapons and other celestial attack weapons to it!

China, for many years, cannot be surpassed.

"Alas, at this point, we must admit that the gap with them is too big. Even if the Americans gather them and the space power of Europe in this regard, there is no way to compare them. Only the more we understand space technology, we The better the development of the technology, the better you can understand that the United States landing on the moon was a joke..." Qian Lao also revealed his deep yearning in his eyes.

The Soviet rocket has one characteristic, that is, its large diameter!

Take Energy, for example, this thing is divided into booster stage and core stage. The booster stage consists of four liquid boosters, each booster is 32 meters long and 4 meters in diameter; the core stage is 60 meters long. , 8 meters in diameter, composed of four liquid rocket engines.

Basically, their boosters are bigger than the main body of Chinese rockets!

It is not bragging that people can send hundreds of tons of things into low-Earth orbit.

Before Liu Yijiu said that the American landing on the moon was fake, there was still a lot of doubt.

After all, the technology required here is simply too complicated.

"Sooner or later, we will have such rockets too!" Liu Yijiu licked his lips.

In front of the launch pad, the third stage of the Long March 3A rocket has been fully docked. After the satellite is docked, the fairing must be installed.By that time, the docking work has basically been completed.

The rocket does not have a booster. The diameter is due to the rocket engine. The bottom first and second booster stage has a diameter of 3.35 meters, while the third stage has also increased to 3.35 meters, and the diameter of the fairing is also 3.35 meters.

From the ground, it looked like a straight pillar standing in front of the launch pad.

Liu Yijiu didn't even ask whether such a design would cause head errors due to gravity problems.

The design of the launch platform can at least not have any problems with various theories.

After the Star Arrow docking is completed and the fairing is added, the docking work has been completed.

The next step is for technical experts to conduct multiple general inspections according to the design.

During the persistence process, different personnel conduct cross-checks to avoid launch failure due to personnel errors.

A rocket is tens of millions, and a satellite is worth the old nose money.

Of course, the loss of money is not too important. The important thing is that once the launch fails, it will be a blow to the confidence of all scientific researchers.

"Below we are carrying out satellite/rocket joint operations, and there must be no mistakes!" In the control center, the most advanced microcomputer produced by the Ninth Institute is completely replaced, with a supercomputer acting as a server.

Next to each computer, there are operators.

They were wearing white lab coats and white hats. Before they entered the control center, they completely removed dust and static electricity.

Liu Yijiu and other members of the military are wearing military uniforms.

Basically, there are very few school officers carrying two bars, most of them are generals carrying shining gold stars.

At the beginning of the order, everyone became nervous, and the breath in the entire control center was a pause.

The operator's body is stretched straight, and watching the status of each system, his eyes are fixed on the various data on the display screen.

Even Liu Yijiu and the others were infected by this tense atmosphere, and they dared not come out.

"The power system is normal..."

"The control system is normal..."

"The telemetry system is normal..."

"The external security system is normal..."

"The Star Arrow separation system is normal..."

...

With the beginning of the joint operation, under the remote control of the operators through radio signals, the status of various systems is fed back to the display screens of each computer through the detection system inside the rocket and satellite.

All systems are normal.

"Is it possible to refuel now?" Some military personnel asked.

Old Qian shook his head, but asked the control center to perform multiple operations to confirm that there were no problems, and then arranged another general inspection.

Then I asked the weather monitoring department and confirmed that there was no abnormal weather at the scheduled time before giving the order to refuel.

For the Long March 3 A rocket, the first and second stages use conventional fuels. The upper part is an oxidizer tank containing liquid nitrous oxide (n2o4), and the lower part is a combustion agent tank containing liquid unsymmetrical dimethylhydrazine (udmh). The third stage is the use of liquid hydrogen and liquid oxygen fuel with high altitude starting capability.

There is a pipeline for refueling in the launch tower, and the fuel is stored in the base before refueling.

"Let's refuel!" Old Qian nodded."When you raise a bet, watch the situation more to make sure there are no problems."
