"Missile defense system? Can this be established? It is difficult to intercept medium and short-range missiles, let alone long-range strategic missiles with a speed of more than Mach 7! As for the establishment of a missile defense system, Long Yaohua felt that there was not much possibility.

Liu Yijiu knew that it was extremely difficult to establish this system, and it took half a century for the Republic to be built before it could barely be put into practice, and the same was true for the US imperialists.

Now, the 002 base is going to start a summary of the 8208 missile transformation project.

"Chief, if not, let's wait until we come back and continue to introduce the missile defense system? There are still many problems in the 8208 project, which are used for export, and there is not much of a problem, but we use them ourselves, which is obviously not possible. We can't transform such a huge missile from the beginning, and wait until the technology advances to continue to transform, otherwise this thing will be too expensive......" Liu Yijiu said to Long Yaohua.

Long Yaohua was immediately surprised.

Isn't this missile very good? The accuracy can even reach within 100 meters! Compared with other domestic missiles, the accuracy is too high.

He is also ready to propose that the Ninth Academy share this guidance technology, if the domestic long-range strategic missiles, such as the Dongfeng-5, Dongfeng-3, and even the Dongfeng-31 and Julang that are being studied, can also be equipped with such a guidance system......

This will completely improve the accuracy of the Republic's missiles as a whole and improve the guidance technology of the Republic's long-range missiles.

"8208 missiles, on the surface it looks good, but you also see it. There is a big gap between the position of the reporting at each monitoring point and the theoretical trajectory. The inertial guidance system of the missile loses its effectiveness, according to calculations, if there is no control chip to adjust the flight attitude and flight trajectory, or according to the inertial guidance, the deviation will reach two thousand meters ......or more," Liu Yijiu shook his head.

Long Yaohua didn't understand technology either, even if someone explained, there were countless trajectory lines of various colors. He didn't know either.

When Liu Yijiu said this, he naturally had no opinions, but followed Liu Yijiu to the 002 base headquarters to add a technical summary meeting.

According to Liu Yijiu. This concerns the entire missile defense system.

It just so happened that Liu Yijiu could explain to him the time on the road.

To explain the missile defense system, neither the United States nor the most powerful countries such as the Soviet Union have systematically established such a network. It is only in the stage of theoretical exploration. When he arrived at the 002 base, Li Rui drove it directly, and the rest of the people were driven to other cars.

"I said Xiao Liu, you have been married to Li Rui for so many years, why haven't you had a child? Are you worried that there is no one to raise or what? "There has been no movement in Li Rui's stomach, and as Li Yunlong's friend, Long Yaohua is naturally strange.

Let's say that there is something wrong with Liu Yijiu. Situ Xue's children are almost a year old.

If there is anything wrong with Li Rui, the best doctors in China have also examined it comprehensively. It doesn't matter if it's Chinese medicine or Western medicine. There is no problem at all.

"Ga ......" When Li Rui heard this, he immediately lost his mind, and saw that the car was about to drive outside the road and hit the factory, so he suddenly came back to his senses and stepped on the brake.

"Rui'er, I don't blame you for this, didn't we say okay, are we still young? Aren't you trying hard every night? Liu Yijiu knew that Li Rui was very unhappy in his heart, because the two had worked hard for so many years, but they had never been able to get a child.

He immediately said to Long Yaohua, "Chief, we are working hard every night for the successor of National Socialism, but we can't let the seeds germinate in the ground." I checked it, and there was nothing wrong with the ground, and there was nothing wrong with the seeds......"

Long Yaohua immediately stopped talking and stopped asking about this matter.

Li Rui cleaned up his mood and quickly got the car back on the road.

If it weren't for the inside of the factory and the mountain roads outside, maybe you would have fallen off the cliff directly.

"Let's talk about the missile defense system!" Long Yaohua sighed, he shouldn't have asked this, Rao was Li Yunlong who asked him to ask on his behalf, and he shouldn't have asked it, especially not in front of Li Rui.

In order to dispel the embarrassment, the topic was immediately changed.

"Regarding the missile defense system, this is also an idea, which I find very useful. After all, in modern warfare, the use of missiles is becoming more and more extensive, especially long-range strikes, support for the battlefield, or long-range precision strikes against important military, political, and economic targets of the hostile country...... Just as the Soviet Union wanted to carry out a surgical, long-range precision nuclear strike against us in the sixties, if we could defend against these missiles, especially outside the borders, the losses would be much reduced......"

Along the way, Liu Yijiu first introduced the entire defense system.

How it will be implemented is not said.

He didn't even say how to build such a defense system.

The current republic simply does not have such sufficient funds, and at the same time, there is no such technology.

The missile defense system must be a system that integrates far, medium, and near, and in particular, to defend against nuclear strikes, it must strike at the missile climb stage or in outer space, otherwise it will begin to change orbit when it re-enters the atmosphere.

The reason why cruise missiles are an important part of the triad nuclear strategy is that they rely on the thrust of the airjet engine and the aerodynamic lift of the wings to fly in the atmosphere in a cruising state. This kind of flight process is difficult to detect, and because the flight attitude is stable in the cruising state, it is relatively easy to implement orbit changes.

More difficult to defend against.

The only difference is that this kind of missile technology is difficult and has many shortcomings that are difficult to overcome, so in the sixties, the Soviet Union and the United States both turned to the development of ballistic missiles, and in the seventies they began to continue to develop when the technology accumulated enough.

"So, our cruise missile research must be accelerated?" Long Yaohua asked with a frown.

It was only after knowing that the United States had successfully researched Tomahawks that the Republic's cruise missile project began. Start. However, there is too much technical difficulty, and there has not been much progress.

Liu Yijiu also knew about this, even in his time. At the end of the seventies, the republic was established, but it was not until the nineties that the republic had practical cruise missile technology......

"Yes, but there are two key technologies, the first is terrain matching technology, and the second is high-performance turbofan engine technology. Turbofan engine technology, we have it at the moment. As long as the miniaturization is solved, it can be used for this, but the terrain matching technology requires a breakthrough in satellite remote sensing technology. Liu Yijiu shook his head.

This is a key technology that restricts the development of cruise missiles in the entire world.

Especially for satellite guidance, the Soviet Union and the United States began to build a global satellite network positioning system at the same time.

In general. Cruise missiles, which are divided into a climb stage, a cruising stage, a dive stage. In the climb phase. Inertial guidance is used. In the cruising phase, GPS (terrain matching) guidance is carried out by satellites, which also allows the missile to adjust its flight trajectory and change its trajectory, and when it comes to the dive phase, some form of optoelectronic guidance will be used......

"So, your 8208 project also uses this technology?" Long Yaohua suddenly thought of the renovation project cooperated by the Ninth Academy and the 002 base. The Ninth Academy is responsible for guidance technology.

From the introduction of the missile defense system to the introduction of the technology of cruise missiles, Liu Yijiu, this kid is preparing for this!

simply asked Liu Yijiu.

"It's kind of a technology here. But we're not using an advanced guidance system. It's the TV signal guidance ......," Liu Yijiu smiled awkwardly.

He thought. Long Yaohua would not react so quickly.

"TV signal guidance?" Long Yaohua asked suspiciously.

"Actually, it's not too complicated technology, but the missile is always detected from the time it is launched to the time it hits the target. The computer chip in the missile will be turned on after launch, and then contact the computer of the guidance workstation, and the guidance workstation will use the calculation formula we set to formulate the flight trajectory line according to the launch coordinates and target coordinates at the beginning, as well as the maximum flight altitude we set...... This is also the theoretical flight trajectory ......" When it comes to these technologies, Long Yaohua is difficult to understand.

This requires not only a good mathematical talent, but also a good understanding of computer science.

"That's it?" Long Yaohua thought for a long time.

Seeing that he was about to arrive at the aerospace base, in front of him was the checkpost that entered the base, but he heard a half-hanging.

"After the guidance station draws out the trajectory line of theoretical guidance, this line will become the guidance flight line of the missile, and the missile will begin to automatically detect the flight trajectory once it enters the cruising stage after the missile climbs during the flight, and compares the trajectory launched by the guidance station at the beginning......"

"Don't talk about it for now, it's too hard to understand. It's not as simple as you say! Long Yaohua was told by Liu Yijiu that he couldn't understand it at all, and there was no real thing to compare, he had to imagine everything out of thin air, and the lines that appeared during the flight were not one or two, so he simply asked Liu Yijiu to stop the introduction.

In front of the checkpoint, Xue Lanqi of Base 002, Chief Engineer Fu Wei and others were waiting. Du Zhongkun is also there.

After some pleasantries, the inspection was completed, and everyone headed inside.

When I arrived at the 002 Base Management Committee, I went straight to the conference room.

In the conference room, the preparations have been completed, and the meeting will start after Liu Yijiu arrives.

Of course, when Long Yaohua arrived here, he naturally had some greetings.

Here, Big Boss Long gave up his right to open, otherwise Liu Yijiu would have to make trouble with him again.

"This renovation project, through our test launch, proved to be very successful. The circumferential accuracy error is within 200 meters, which is our goal...... "Liu Yijiu is still as usual, first affirm.

His words were interrupted by enthusiastic applause.

Of course, the slaps were made loud by the technicians and managers on the aerospace side. But Du Zhongkun and the others from the Ninth Academy just slapped their hands very plainly.

"However, this is not the end of our project, because our project is not as good as we imagined. The situation, Chief Engineer Du Zhongkun will introduce it to you......" Liu Yijiu's words were like a basin of cold water that extinguished the boiling hearts of many personnel in the 002 base.

Du Zhongkun knew Liu Yijiu's thoughts.

As the chief engineer, after seeing the detected trajectory flight line, he understood that such a missile alone could not be considered a success at all.

Technology can improve a lot, and to achieve such precision, there is a lot of luck in it.

They need to make sure that every missile is as accurate as possible.

"Everyone looked at the trajectory of the missile during the flight, and also saw the comparison after the correction of the missile guidance process. Hongqi-2 was already backward in terms of performance, but after the improvement, it was replaced with a small wing, and the stability was improved, but it was not as good as we imagined......" Du Zhongkun drew a straight line on the blackboard used for the demonstration, and then a wavy line.

"This straight line represents the theoretical flight trajectory line of our missile, and this wavy line represents the actual flight trajectory line, which is not the most accurate, but it is almost ......" After Du Zhongkun drew it, he introduced the situation to everyone.

"According to our analysis, it is inferred that if the design is improved in the shape to increase stability, if the price comparison is stable during the flight, the inertial guidance will not deviate too much during the climb phase...... In the process of our test launch, there is obviously a gap in inertial guidance, and at the same time, because of the aerodynamic layout, coupled with the problems of our control chip and the entire control system, we will constantly adjust during the flight, either too left, too right, or too high or too low......" Du Zhongkun's explanation made the originally excited aerospace and others also silent.

He was telling the truth.

Flight stability is somewhat worse.

In the past, although the performance of the Hongqi-2 was not advanced enough, the large wing surface could ensure the flight stability of the missile, but now it has been changed to a small wing surface, but the stability is much worse.

"So, we have to improve this missile even further. This level of accuracy is not the highest level of accuracy we can achieve...... Exports are not a problem, but we must ensure that our own troops are equipped with the ultimate in accuracy that we can achieve! "Liu Yijiu's purpose is obvious, the whole team, continue to study.

"As for how to solve the technical problems that arise this time, we will discuss them today, and then the project teams will solve them separately......"

"Director Liu, if we continue, what will we do with our mission?" Liu Yijiu didn't have a good heart, Xue Lanqi and others were always on guard.

I didn't expect him to do such a thing.

If the project is not completed, the team cannot be disbanded......
