The "opportunity to instantly change the trajectory and avoid anti-missile interception" that Ding Hui mentioned was not an interceptor missile launched against the anti-missile system, but a trajectory that was set before launch.
Even if there is no interceptor missile, it will definitely change course because it has been preset.
The reason lies in the calculation method.
The three-dimensional function trajectory correction made by Wang Hao is aimed at the "1-to-1" situation. "1-to-1" means that a fixed function changes trajectory to another fixed function.
No matter what method is used to change the trajectory, the missile route after the trajectory change must be on a fixed function, so that it can be slowly corrected to the original trajectory based on the calculation results.
This is where the limitations come in.
Including real-time speed, height, direction, etc. must be set in advance to truly realize one-to-one orbit change.
The one-to-one orbit change is still very restrictive, but if you think about it carefully, you will know that the effect will still be quite amazing.
Most countries do not have a complete anti-missile system. In other words, except for the top countries, no other country has a complete anti-missile system.
The so-called perfect anti-missile system means that the entire process from the launch of the missile to the time it hits the target can be used for anti-missile interception.
The missile launch is divided into three solid stages, one is the ascent stage, the other is the middle stage, and the final stage, which is the acceleration stage, the midway stage and the re-entry stage.
Strike stage.
In the first stage, the missile is usually launched on its own territory, and the interception range is not enough. In the seventh stage, the missile will be in the small atmosphere, which is very low and difficult to reach.
Even if there is no perfect anti-missile system, it is very difficult to retreat and intercept at those two stages.
The eighth stage is the strike stage of re-entering the small atmosphere. The ballistic missile flies at a very alarming speed, but it is also the main interception stage of the special air defense system.
A small number of air defense systems are designed for slow-moving missiles, and are not mainly designed for interception in the small atmosphere.
At the same time, the interception range is also unlimited.
For example, the famous Patriot system is the "high-level missile defense system" among the Americen air defense systems. On the contrary, its performance is still very weak, but it actually intercepts i
degree, especially only within a range of 80 kilometers.
If the incoming missile can suddenly change its trajectory at a low altitude of 80 kilometers away, all the calculations behind the air defense system will be useless. Even if the missile is launched,
The missile also has no way of hitting its target.
It is also very easy for the air defense system to lock the route of the incoming missile.
One is that it takes time.
The other is because "it takes a certain amount of time to correct the trajectory."
Outside of the trajectory correction time, the missile's trajectory is constantly changing, so there is no way to achieve accurate calculations.
After the trajectory of the missile is modified, it may be very close to the concentrated target, and the time and space for interception will be lost.
"The trajectory change must be done at a low altitude of 80 to 70 kilometers away. If the trajectory change time is extended, your conventional missiles will not be able to break through the extremely small part of the high-altitude anti-reflective missiles.
system. 「
Wang Hao concluded excitedly, "Even if the opponent's anti-missile system can work, it may be necessary to launch eight, seven, or even fewer anti-missile missiles.
Enough to ensure effective interception. 「
By the time Wang Hao finished speaking, everyone in the office was very excited.
Zheng Guofeng was so excited that his face was red. Such skill was really amazing.
Conventional missiles only have conventional ballistics and are difficult to be calculated by the anti-missile system, making it difficult to break through the air defense lock.
The cost of Qian Xuesen's ballistics is very low. Even if conventional missiles are used, it is difficult to continue until they hit the target and achieve universal coverage.
The technology is the same now.
That technology must be developed and matured, and a small series of missiles cannot be retrofitted and retrofitted with that technology and equipment to achieve weak penetration capabilities.
The most important of these are short- and medium-range missiles, because smaller intercontinental missiles, or missiles that can achieve speeds of nearly Mach 20, require orbit changes to achieve this.
If it hits the target, it cannot be intercepted as long as it is launched.
However, the following two missiles are commonly used and are very low cost.
If a technology can achieve universal coverage under conventional missiles, it will become very worthless.
The meeting begins.
Everyone was discussing excitedly.
We are full of expectations for new technologies. Whenever we think that conventional missiles in the future will be able to directly penetrate the enemy's anti-missile system that retreats first, we feel very excited and even excited.
I can't wait to see that kind of technology.
The only person who wasn't excited was not Chen Mengmeng. I knew what was going on, and I just heard about the technique of retreating first.
"Is that imagining?"
Chen Mengmeng was not confused yet, so I simply asked Pang Sibo, "Where did that low-end technology come from? Is it so powerful? Can it directly derail your conventional missiles?"
force? 「
Pang Sibo looked at Chen Mengmeng with a smile, "It's possible that it wasn't what he said in the next two days."
"ah?"
Chen Mengmeng was stunned for a moment, then mouthed two words, "Ji Yao?"
Ji Yaoyan nodded with a smile.
Chen Mengmeng was immediately surprised. I discussed it with Zheng Guofeng later. I just wanted to ask Ji Yao for advice. How come we came up with a solution?
And that solution is to directly change the trajectory of conventional missiles?
The other party - it took him half a month to come up with a feasible method for orbit change calculation?
That’s amazing!
"It's strange that I have always attached great importance to Ji Yao. What a great mathematician!"
Chen Mengmeng felt very shocked when he thought about it, and I also became excited before that. Being able to change the trajectory of conventional missiles cannot be said to have improved domestic missile technology.
grade.
If the technology can really mature and spread to some special types of missiles, it will be equivalent to upgrading existing missiles.
What a small development is that?
It spans ten years at most, or even less than seventeen years!
I took a deep breath. The more I thought about it, the more excited I became. It took me a long time to think of the real thing. "By the way, Professor Zheng, the date has been confirmed. On the 8th of last month, Zhao Xing
Academicians will come. 「
"At that time, other leaders from District 8 will also come. We want to synthesize the existing low-end technologies and demonstrate the future research and development direction."
Pang Sibo immediately became concerned after hearing this and said, "What research direction are we talking about!"
"Isn't that the direction?"
"When we demonstrate what tube is, we have to study that technology and we must complete and perfect it!"
I stood up and said, ":Just be quiet, little family! Just be quiet!"
"The next work for you is not to focus on that data, but to understand all the mathematical logic in it, and then demonstrate together how to implement it!"
"When people from District 8 come last month, let us see the results of your work at Institute 137!"
"right!"
":Xiaojia, continue your research!"
Everyone became very positive.
Zheng Guofeng nodded with satisfaction. I then said to Chen Mengmeng, "By the way, tell me Xu Chao's name too. You guys are greedy for credit."
"It's a mistake. If you came to District 8 last month, please report it to us."
Chen Mengmeng nodded and said.
What can mathematics do?
There is so little that mathematics can do.
Mathematics is indispensable in all fields of application, and breakthroughs in mathematics can often bring about major and small breakthroughs in scientific foundations.
However, often top mathematicians do not pay attention to the application field, or even care about the application at all. What we care more about is theoretical research.
This may also be called attention, but it is a fascination with mathematical theories.
Xu Chao is like that.
Zheng Guofeng is like that too.
We demonstrated the logical problems of simplicity theory together, and we continued to study them intermittently for a few weeks. We just sorted out the logical problems of the event, and we were able to enjoy it.
Get intoxicated.
"For 1, it is still a question of P, and it has not reached the level of P."
"Theoretically speaking, that kind of problem will never be solved. All you have to do is find complicated methods."
"No matter how small the number of events is, it has no lower limit. Counting from one to 100 million cannot be completed even if it does not take 100 million time."
"You are analyzing from the node. Event A is very strange and contains few events of the same type, but event B is fixed. "
"Starting from commonalities is one way, but you can't think of other methods, such as setting a non-universal set and using a set to describe events."
"All A events correspond to B events, and the commonality of A events is also very obvious. For example, they are all parameters of eight-dimensional curve functions, and there may be other functions.
The difficulty lies in determining the parameters. 「
"need…"
The two of them were constantly discussing, sometimes turning into arguments, or just thinking together in silence.
That hadn't lasted a week.
The working hours every day are more than ten hours, and they are not just discussions, arguments, and thinking, and they even end up doing weird things when they want to get results.
For example, Zheng Guofeng simply lay down under the table. I think that action might make the cerebellar cortex more active, and he almost fell asleep.
Xu Chao stood by the window for a long time. I found that thinking like that was really boring.
For example, I noticed that a large bird's droppings almost fell under a student's head.
I don’t know if it has anything to do with research, but often letting your mind wander and focusing your attention is also a short break for the cerebellum to degenerate.
"What would happen if we reversed the analysis of the incident?" Zheng Guofeng suddenly proposed such a method.
Xu Chao continued to think, but he didn't understand the simple logic.
Ji Yao came to deliver lunch to the two of them.
I put my lunch under the table without interrupting their thoughts. Xu Chao and Zheng Guofeng continued to discuss.
At that time, Xu Chao suddenly said, "Ding Hui, he is going to move!"
Ding Hui didn't understand.
"He went to stand next to the wall, that's what happened." Xu Chao directed Ding Hui, observing again and again, and continued, "Can he stand on his head?"
"Handstand?"
"right."
Ding Hui stood firm for a long time, put his hands on the ground and asked, "Is that so?"
"Yes, can you get up?"
"certainly."
Ding Hui confidently used his hands to turn over and put his feet on the wall.
Xu Chao and Ji Yaoyan stood beside each other, pressing their chins and watching carefully.
Zheng Guofeng thought about it and said, "It's not the other way around. Logically, it's the transformation of the end point and the origin."
Xu Chaodao said, "It is certain. Without some logic, it will still violate the established laws, because the inner influence is very small. When he sees my clothes, he still violates the laws of gravity.
The pants are hanging down, but the pants are not hanging up. Nothing is affected by the inside, and they will be reversed directly. 「
"It's like that."
Zheng Guofeng nodded thinking, then walked to the whiteboard, took a pen and started writing, "Looking at your research yesterday, there are few factors that will be affected by inversion.
We changed positions and continued the discussion.
Ding Hui continued to hold his hands on the ground, holding it in until his face turned red. I knew it was time to get up when I saw Luo Dayong walking back from the door.
Luo Dayong walked back on his feet. You turned to look at Ding Hui, feeling confused.
Ji Yao wanted to embarrass the boy in front of her, so I was about to put my legs up when I saw Luo Dayong crossing his hands and making a "stop" gesture.
Ji Yaoyan came over and said loudly, "Wait a minute."
"do what?"
Luo Dayong took out his mobile phone and slowly pressed the photo button on Ji Yao. He also said loudly, "Take two photos as a souvenir and send them to Moments."
Ding Hui quickly came up from the wall and gritted his teeth when he looked at Ji Yaoyan again.
That boy is so pale and wilted!
But because I was worried about disturbing Xu Chao and Ji Yaoyan's discussion, I didn't start a fuss on the spot, so I could only hold it in and walk out. As a result, Ji Yaoyan didn't share it with anyone else.
It's over.
Until the very end, Ji Yao and Zheng Guofeng were still able to solve the problem.
Xu Chao felt that there was only the last chance left to solve the computational logic problem, but he couldn't catch such a glimmer of inspiration.
I checked the time and decided to give a lecture to the students.
"If you tell the students about the problem, they might be able to figure it out."
I said that.
Zheng Guofeng was completely confused after hearing this.
The content of the big lecture that day turned into the event analysis problem of simplicity theory. That problem made not only graduate students, but also doctoral students and professors dizzy.
dizzy.
Fortunately, Ji Yao explained it very seriously and clarified the logic in between.
Xiaojia can still barely understand it.
"That is a time logic analysis problem. You have thought of a good way. It is not to invert cause and effect, but inverting cause and effect will cause new problems. No one
Events will be completely transformed due to the inversion of cause and effect. 「
"Because of the influence inherent in existence."
"There are very few factors corresponding to one factor. The logic of the event is not a P1 problem. Theoretically speaking, it is still a P problem..."
Everyone was listening attentively.
That is a novel content for us. Even if we have no understanding of simplicity theory, we have never heard of such a profound logical problem.
Xu Chao: The brief explanation lasted about 80 minutes. When I talked about the problem of causal reversal, I suddenly caught this glimmer of inspiration.
[Task 8, inspiration value +19.]
Gone!
I couldn't control the joy on my face. I immediately put down the things in my hands, walked out of the conference room and rushed to the office.
The students in the conference room didn't know what Xu Chao was thinking, but no one knew what he was thinking.
Zheng Guofeng hurriedly followed.
"you understood!"
Xu Chao sat behind his desk and finished taking notes, "The key to the problem is to grasp the most important calculations, but to regress all analyses."
"Those parameters are simple and each one is included, but they are also important and important."
"You cannot regress the classification of parameters to set sets and perform regression analysis for each set."
"That would make the logic very muddy."
―In one sentence, it’s clear.
Ji Yaoyan was thinking hard and knew how to solve the problem.
I am focusing on the P problem of its transition theory, while Xu Chao is focusing on using the computational logic of combing to study the transformation trajectory of a random eight-dimensional function.
Because there is no basic support for the research on one-to-one eight-dimensional function transformation trajectories, as long as the calculation logic is sorted out, the one-to-one random eight-dimensional function transformation trajectory cannot be perfected:
calculation method.
Before I got the first hint of inspiration and sorted out the simple calculation logic, the research ideas were not very muddy.
Xu Chao finished his research summary.
Zheng Guofeng also made a summary. I summarized the solution given to the one-to-one P problem.
That theoretical research is enough to support writing a top-notch paper.
Regarding the research on simplicity theory, our assignment is still one author and one corresponding author.
All the research papers on simplicity theory were left to Zheng Guofeng to write.
Zheng Guofeng was not excited either.
Under the research direction of simplicity theory, it is very easy to produce results, but now there are no new results.
Even the results produced together with Xu Chao are remarkable.
Even if Ji Yao made the smallest contribution, for such important research, collaborative research objects are also very important. Academically speaking, a small part of the research is done by one person.
It’s just that the two of us completed the first-class theoretical results, which are very impressive.
For Xu Chao, it was just a special achievement.
I am more concerned about the research on "random eight-dimensional function curve correction" because I know that similar research has a lot of application value.
Taking the missile as an example, during the flight of the missile, it cannot regress to random route changes, and it cannot quickly adjust to the original route through calculation and adjustment.
That kind of correction can only be reversed once. As long as there is no support from the foundation, theoretically there can be many corrections.
As the technology matures, as long as the missile is launched, it cannot automatically retreat to "avoid obstacles". From launch to hitting the target, it doesn't matter how many times it encounters it along the way.
Interception can be avoided by automatically changing the trajectory. At the same time, the route will become "very weird", and there is no way to perform backward calculations.
What's more, maybe the launching party cannot be sure of the specific trajectory.
In short, the final route will be corrected to the original one.
Facing such missiles, any air defense system will be meaningless.
