The "opportunity to change the trajectory in an instant and avoid anti-missile interception" that Ding Hui mentioned was not an interceptor missile launched against the anti-missile system, but a trajectory change 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 its 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 achieve one-to-one orbit change.
The one-to-one orbit change form is still very restrictive, but if you think about it carefully, you will know that the effect will still be quite amazing.
The vast majority of countries do not have a complete anti-missile system, or in other words, except for the top countries, no other country has a complete and complete anti-missile system.
The so-called perfect anti-missile system means that the entire process from the launch of the missile until it hits the target can be used for anti-missile interception.
The missile launch is divided into three stages in total, 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 strike stage.
In the first stage, the missile is usually launched from its own territory, and the interception range is not enough. In the second stage, the missile will be outside the atmosphere, which is a height that is difficult to reach.
Even with a complete anti-missile system, it is very difficult to intercept at these two stages.
In the third stage, the strike stage of re-entry into the atmosphere, the flight speed of ballistic missiles is very alarming, but it is also the main interception stage of ordinary air defense systems.
Most air defense systems are designed to target rapidly incoming missiles, mainly targeting interception within the atmosphere.
At the same time, the interception range is also limited.
For example, the famous Patriot system is a "low-level missile defense system" in the Amerikan air defense system. Its performance is still very strong, but the actual interception height is generally only within a range of thirty kilometers.
If the incoming missile can suddenly change its trajectory at an altitude of thirty kilometers, all the previous calculations of the air defense system will be useless, and even if the air defense missile is launched, it will not be able to hit the target.
It is also very difficult for the air defense system to lock the route of the incoming missile.
One is that it takes time.
The other reason is that ‘trajectory correction takes a certain amount of time’.
During the trajectory correction time, the trajectory of the missile is constantly changing, and it is impossible to achieve accurate calculations at all.
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.
"If we change the trajectory at an altitude of 30 to 40 kilometers and extend the trajectory change time, our conventional missiles can also break through most low-altitude anti-missile systems."
Ding Hui concluded excitedly, "Even if the opponent's anti-missile system can work, it may be necessary to launch three, four, or even more defense and control missiles to ensure effective interception."
After Ding Hui finished speaking, everyone in the office was very excited.
Zheng Guofeng's face turned red with excitement. Such technology was really amazing.
Conventional missiles only have conventional trajectories, which can be easily 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 high. Even if conventional missiles are used, it is difficult to continue until they hit the target, and they cannot achieve universal coverage.
Today's technology is different.
If this technology can be developed and matured, many series of missiles can be modified and equipped with this technical equipment to achieve strong penetration capabilities.
The most important among them are short- and medium-range missiles, because larger intercontinental missiles, or missiles that can achieve speeds of nearly Mach 20, do not need to change their trajectory to hit the target. As long as they are launched, they cannot be intercepted.
However, the above two missiles are not commonly used, and the cost is very high.
A technology that can achieve universal coverage on conventional missiles will become very valuable.
End of the meeting.
Everyone was discussing excitedly.
They are full of expectations for new technologies. Whenever they think of future conventional missiles that can directly penetrate the enemy's advanced anti-missile system, they feel excited and can't wait to see this technology.
The only one who wasn't excited was Pang Sibo. He didn't even know what was going on, but he heard such advanced technology.
"Is this imagining?"
Pang Sibo was still a little confused. He simply asked Zheng Guofeng, "Where does this high-end technology come from? Is it so powerful? It directly allows our conventional missiles to have the ability to change orbits?"
Zheng Guofeng looked at Pang Sibo with a smile, "It's the impossibility you said two days ago."
"ah?"
Pang Sibo was stunned for a moment, then mouthed two words, "Wang Hao?"
Zheng Guofeng nodded with a smile.
Pang Sibo was immediately surprised. He had discussed it with Zheng Guofeng before and just wanted to ask Wang Hao for advice. How come he came up with a solution?
And this solution is to directly achieve the trajectory change of conventional missiles?
It took the other party half a month to come up with a feasible method for orbit change calculation?
This is so amazing!
"No wonder the institute has always attached great importance to Ding Hui, the mathematician is really amazing!"
Pang Sibo felt very shocked when he thought about it, and then he also became excited. Being able to change the trajectory of conventional missiles can be said to have raised domestic missile technology to a higher level.
If the technology can really mature and spread to some ordinary missiles, it will be equivalent to upgrading all missiles.
What a big development this is?
It spans at least ten years, and even spans more than fifteen years!
This chapter is not finished yet, please click on the next page to continue reading the exciting content! He took a deep breath, and the more he thought about it, the more excited he became. It took him a long time to think of the real thing, "By the way, Professor Zheng, I'm sure this time
The date is set, Academician Zhao Xingli will be here on the 3rd of next month."
"At that time, other leaders from the third district will also come. They want to synthesize the existing high-end technologies and demonstrate the future research and development direction."
After hearing this, Zheng Guofeng immediately said indifferently, "What research direction are we talking about!"
"Isn't this the direction?"
"No matter what they argue, we must study this technology and complete it and perfect it!"
He stood up and said, "Everyone, be quiet! Be quiet!"
"Our next work is to understand all the mathematical logic of this data, and then work together to demonstrate how to implement it!"
"When people from the third district come next month, let them see the results of our work at Institute 137!"
"right!"
"Everyone, keep researching!"
Everyone became very positive.
Zheng Guofeng nodded with satisfaction, and then said to Pang Sibo, "By the way, also report Wang Hao's name. We can't be greedy for credit."
"That's for sure. When people from the third district come next month, just report it to them."
Pang Sibo nodded and said.
…
What can mathematics do?
There are so many things that mathematics can do.
Mathematics is inseparable from every field of application, and breakthroughs in mathematics can often lead to major breakthroughs in scientific foundations.
However, often top mathematicians do not pay attention to application fields, or even do not care about applications at all. They care more about theoretical research.
That may not be called attention, but rather a fascination with mathematical theory.
Wang Hao is like this.
The same is true for Luo Dayong.
They demonstrated the logical issues of complexity theory together, and they continued to study them for more than a week. They just sorted out the logical issues of the event, and they were able to enjoy it and indulge in it.
"N versus 1 is still a P problem, and it has not reached the level of NP."
"Theoretically speaking, this type of problem will always be solved one day. All we have to do is find simple methods."
"No matter how large the number of events is, it has an upper limit. Even if it takes 100 million times, counting from one to 100 million can still be completed."
