Super military empire

"Missile defense system? Can this be established? Short- and medium-range missiles are difficult to intercept, not to mention long-range strategic missiles that can exceed Mach 7!" Long Yaohua does not think there is much possibility for the establishment of a missile defense system.

Liu Yijiu knew that it was extremely difficult to establish this system. It took half a century for the Republic to be practical before it was built, and the United States did the same.

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

"Chief, or else, let's wait until we come back and continue to introduce the missile defense system? There are still many problems in the 8208 project. It is not a big problem for export, but it is obviously impossible for us to use it. We can't make such a huge The missile was modified from the beginning, and it will continue to be modified until the technology has improved, otherwise this thing is 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!This is far more accurate than other domestic missiles.

He is also going to propose that the Ninth Academy share this guidance technology. If domestic long-range strategic missiles, such as Dongfeng-5, Dongfeng-3, and even the Dongfeng-31, Julang, etc. under study, such guidance systems should be installed... …

This can completely improve the accuracy of the Republic’s missiles as a whole and enhance the guidance technology of the Republic’s long-range missiles.

"The 8208 missile looks good on the surface, but you have also seen that there is a big gap between the position reported at each monitoring point and the theoretical trajectory. As a result, the missile’s inertial guidance system loses its effectiveness. Calculate, if there is no control chip to adjust the flight attitude and flight trajectory, the deviation will reach two kilometers or more..." Liu Yijiu shook his head.

Long Yaohua didn't understand the technology. Even if someone explained, he didn't know countless traces of various colors.

Under the circumstances that Liu Yijiu said so, he naturally didn't have any opinions, but followed Liu Yijiu to the 002 base headquarters to add a technical summary meeting.

According to Liu Yijiu, this is related to the entire missile defense system.

Just in time, Liu Yijiu can explain to him during the time on the road.

To explain the missile defense system, in the most powerful countries such as the United States and the Soviet Union, such a network has not been systematically established. It is only in the stage of theoretical exploration. When it arrives at the 002 base, Li Rui will directly drive the car. The others, They were all driven to other cars.

"I said, Xiao Liu, you have been married to Li Rui for so many years, why have you never had a child? Are you worried that no one will raise it or something?" There has been no movement in Li Rui’s stomach. As Li Yunlong’s friend, Long Yaohua is naturally strange.

Let’s talk about Liu Yijiu’s problem, Situ Xue’s child is almost one year old.

As far as Li Rui has any problems, the above has been thoroughly checked by the best doctors in China.Whether it is Chinese medicine or Western medicine, there is no problem.

"Hey..." When Li Rui heard this, he went away, seeing that the car was about to drive out of the road and hit the factory building, he suddenly recovered and stepped on the brake.

"Rui'er, you are not to blame for this matter, let's just say, are we still young? Aren't we working hard every night?" Liu Yijiu knew that Li Rui was very upset because the two worked hard. For many years, I have not been able to produce a child.

Immediately he said to Long Yaohua, "Chief, we are working hard for the successor of National Socialism every night, but we have not been able to let the seeds germinate in the ground. After inspection, there is no problem with the ground, and the seeds are without problems..."

Long Yaohua immediately stopped asking about this matter.

Li Rui cleared up his mood and quickly returned the car to the road.

If it weren't for the inside of the factory or the mountain roads outside, it might have fallen directly off the cliff.

"Tell me about the missile defense system!" Long Yaohua sighed. He shouldn't ask this. If Li Yunlong asked him to ask on his behalf, he shouldn't, especially in front of Li Rui.

In order to dispel the embarrassment, he immediately changed the subject.

"As for the missile defense system, this is also an idea. I think it is a very useful idea. After all, in modern warfare, missiles are used more and more widely, especially for long-range strikes, support for the battlefield, or important military and political issues for hostile countries. Long-range precision strikes on economic targets... Just like the Soviet Union wanted to carry out a surgical long-range precision nuclear strike on us in the 1960s, if we can defend against these missiles, especially outside the country, we will lose. It will reduce a lot..."

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

How to implement it, did not say.

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 an integrated system of far, middle and near, especially for defense against nuclear strikes. It must be attacked during the missile's ascending phase or in outer space. Otherwise, it will start to change orbit when it enters the atmosphere again.

The reason why a cruise missile is an important part of the Trinity nuclear strategy is that it relies on the thrust of the air jet engine and the aerodynamic lift of the wings to fly in the atmosphere in a cruise state.This kind of flight process is difficult to detect, and since the flight attitude is stable in the cruise state, it is easier to implement orbit changes.

More difficult to defend.

The only difference is that this kind of missile technology is difficult and has many deficiencies that are difficult to overcome. Therefore, in the 1960s, both the Soviet Union and the United States turned to the development of ballistic missiles. In the 1970s, the technology accumulated enough before it started. continue to develop.

"So, our cruise missile research must speed up the process?" Long Yaohua asked frowning.

It was only after knowing the success of the American Tomahawk research that the Republic’s cruise missiles began to be established and started.But there is too much technical difficulty, and there has not been much progress.

Liu Yijiu also knew about this. Even in his time, the Republic was established in the late 1970s, but it was not until the 1990s that the Republic had practical cruise missile technology...

"It is indeed necessary, but there are two key technologies. The first is terrain matching technology, and the second is high-performance turbofan engine technology. We currently have turbofan engine technology. As long as we solve the problem of miniaturization, it can be used Above this, but 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 throughout the world.

Especially satellite guidance, so the Soviet Union and the United States will start building a global satellite network positioning system at the same time.

Under normal circumstances, cruise missiles are divided into climb phase, cruise phase, and dive phase.In the climb phase, inertial guidance is used, and the satellite is used for GPS (terrain matching) guidance during the cruise phase, so that the missile can adjust its flight trajectory and change its trajectory. When it comes to the dive phase, it will adopt some form Photoelectric guidance...

"So, your 8208 project is also using this technology?" Long Yaohua suddenly thought that the Ninth Academy is responsible for the guidance technology in the transformation project of the Ninth Academy and 002 Base.

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

Simply asked Liu Yijiu.

"It's one of the technologies inside. But what we use is not an advanced guidance system. Instead, we use TV signal guidance..." Liu Yijiu smiled awkwardly.

He thought that Long Yaohua would not react so quickly.

"TV signal guidance?" Long Yaohua asked suspiciously.

"In fact, it's not too complicated technology, but the missile is always tested from launch to hitting the target. The computer chip in the missile will be turned on after launch, and then it will contact the computer of the guidance workstation for guidance. At the beginning, the workstation will use the calculation formula we set to formulate the flight trajectory based on the launch coordinates and target coordinates, as well as the highest flight altitude we set... This is the theoretical flight trajectory..." It is difficult for Long Yaohua to understand these technologies.

This requires not only a very good mathematics talent, but also a good understanding of the freshman computer.

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

Seeing that he was about to arrive at the aerospace base, the checkpoint that entered the base was in front of him, but he heard a sling.

"After the guidance workstation has drawn the theoretical guidance trajectory, this line will become the guided flight path of the missile. During the flight of the missile, after climbing, once it enters the cruise phase, it will automatically detect the flight trajectory. Compare the trajectories launched by the guidance workstation at the beginning..."

"Don't say it for the time being, it's too difficult to understand. This thing is not as simple as you said!" Long Yaohua was said in a cloud by Liu Yijiu, there is no way to understand it, and there is no real thing to do. For comparison, he had to imagine everything out of thin air, and the lines that appeared during the flight were not one or two, so let Liu Yijiu stop the introduction.

In front of the checkpoint, 002 base Xue Lanqi, chief engineer Fu Wei and others are all waiting.Du Zhongkun is also there.

After a lot of greetings, the inspection was over, and everyone went inside.

Arrived at the 002 base management committee, went straight to the meeting room.

In the meeting room, the preparations are already completed, and the meeting will start after Liu Yijiu is in place.

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

On this side, Long Dao gave up his right to start, or Liu Yijiu would have to make trouble with him again.

"This renovation project has proved to be very successful through our test shots. The accuracy of the circumference is within two hundred meters. This is our goal..." Liu Yijiu is still as usual and affirms first.

His words were interrupted by enthusiastic applause.

Of course, the slap shots are all the technicians and managers from the aerospace side.But Du Zhongkun and others from the Ninth Academy just slapped their hands very flatly.

"However, this is not the end of our project, because our project is not as good as we imagined. The situation, let's introduce the situation to you by Chief Engineer Du Zhongkun..." Liu Yijiu said, like a pot of cold water. Extinguished the boiling hearts of many personnel in 002 base.

Du Zhongkun knew Liu Yijiu's mind.

As the chief engineer, after seeing the detected trajectory flight line, he understood that just such a missile would not be successful at all.

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

They have to ensure that each missile can achieve better accuracy.

"Everyone looked at the trajectory of the missile during flight, and also saw the comparison after the missile guidance process was revised. The Hongqi-2 was originally relatively backward in performance. After the improvement, it was replaced with a small wing surface, and the stability was improved. But it is not as good as we thought..." Du Zhongkun drew a straight line on the blackboard used for the demonstration, and then another wavy line.

"This straight line represents the theoretical flight trajectory of our missile, and this wavy line represents the actual flight trajectory. This is not the most accurate, but it is almost the same..." Du Zhongkun drew it and faced it. Everyone introduced the situation.

"According to our analysis, it is inferred that if we make some improvements to the shape and increase the stability, if the price is stable during the flight, the inertial guidance will not deviate too much during the climb phase... During our test launch. There is a clear gap between inertial guidance and inertial guidance. At the same time, because of the aerodynamic layout, coupled with the problems of our control chip and the entire control system, we will continue to adjust during the flight, either over the left or over the right, or Too high or too low..." Du Zhongkun's explanation silenced the originally excited Aerospace and others.

He was telling the truth.

The flight stability is a bit poor.

Although the performance of Hongqi-2 was not advanced enough in the past, the large wing surface can ensure the flight stability of the missile. Now it is changed to a small wing surface, which is much worse.

"So, we must further improve this missile. Such accuracy is not the highest level of accuracy we can achieve... Export is not a problem, but we must ensure that our own troops are equipped with the ultimate 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 emerged this time, let's discuss them today, and then the project teams will resolve them separately..."

"Director Liu, if we continue, what should we do with our mission?" Liu Yijiu was not at ease, and Xue Lanqi and others were always on guard.

It never occurred to him that he would do such a thing.

Without completing the project, the team will naturally not be able to disband...
