The experimental base of the third zone of the aerospace industry is located in a barren mountain far away from the hustle and bustle of the city, and the car drove for more than two hours before arriving in front of the experimental base.

A receptionist opened the door.

Wang Hao stepped out of the car and saw a group of people walking towards him.

At the front was an old man in his sixties wearing a shirt and military trousers, with slightly gray hair but looking energetic.

After the old man walked over, he held Wang Hao's hand tightly with both hands, and said enthusiastically, "Academician Wang, it can be regarded as waiting for you."

The person next to him introduced, "This is Academician Zhao Xingli, the head of the third district."

Wang Hao nodded and smiled, "Academician Zhao, you are too polite."

After that, the staff next to him helped introduce other people, and standing next to Zhao Xingli was Zheng Guofeng, the chief researcher of the 137 Institute.

Zheng Guofeng treated Wang Hao even more enthusiastically than Zhao Xingli, he took Wang Hao's hand, and said with some excitement, "You have greatly improved our missile interception technology!"

Wang Hao knew that his mathematical research was related to missile evasion and interception, but he still didn't know the specific situation, so he asked, "What did you research?"

"Orbit Jets!" Zheng Guofeng said, "To be precise, it is called a missile anti-interception orbit change jet."

"We are based on the mathematical solution you provided to achieve the anti-interception orbit." Zheng Guofeng said with some pride, "We have created an orbit-changing jet, which weighs only about 10 kilograms, which can be installed behind the warhead and play an anti-interception role when it is 50 kilometers away from the target, that is, the final path of the missile."

Zheng Guofeng said, and pulled him into the experimental base together.

They talked as they walked.

Zhao Xingli, Zheng Guofeng, and Wang Hao walked in the front together, and the others followed behind, and they kept looking at Wang Hao, "Academician Wang Hao, you are really young, this time you have seen a real person."

"I've been seeing it on the news, and I feel that he himself is younger than on the news, so young, he is already ......."

"That's not comparable!"

"The mathematical research done by Academician Wang Hao is so valuable that he can directly design a new device!"

"Those are just a small result of his, I didn't see the news that his recent research is the speed of light, and I can't even think of explaining the problem of the speed of light."

"I haven't seen any anti-gravity research, and other people's research is much more advanced than ours......

Zhao Xingli and Zheng Guofeng, who were in front, explained their results and the experiments to Wang Haohao together.

They created an anti-interception orbit-changing jet that could be attached to a missile.

This orbit-changing jet is installed behind the missile's warhead, that is, in the middle of the missile, shares radar data with the missile, has an independent electronic system, and also carries three explosive jets for temporary jet changes the direction of the warhead.

Because it is installed behind the warhead, it works after the rear of the bullet body is detached, almost about 50 kilometers from the ground.

"At this altitude, ordinary anti-missile systems cannot intercept it."

"For example, the strike altitude of an internationally renowned Patriot will not exceed 50 kilometers, and it should normally be around 30 kilometers."

"The orbit-changing jet can share missile radar data, and when it detects the approach of an anti-warhead, there will be a jet launch to change direction."

"The next 10 kilometers will be corrected, but there will be deviations......

Zheng Guofeng shook his head a little helplessly, "No matter how we correct the calculation method, there will be deviations in the path, if it is intercepted at an altitude of 30 kilometers, it will not affect the target, but the deviation still exists, which will affect the accuracy of the missile."

"If it's at an altitude of 10 kilometers, there may be a problem, because the power of the individual jets after the missile rotates, sometimes it is weaker, sometimes it is stronger, and the path correction is not so accurate."

Wang Hao nodded in understanding, "It's normal for there to be deviations, because some of them are approximate calculations, and it is impossible to completely guarantee the accuracy."

Zheng Guofeng's brows loosened a little, and he suddenly felt affirmed.

Because the experiment was carried out at one o'clock at noon, Wang Hao still walked around the experimental base first, visited the various facilities, and the manufactured equipment.

Zhao Xingli found that Wang Hao was very interested in military facilities, and took him to 30 kilometers away to see the anti-aircraft missiles that were on standby.

He also said, "What we are going to experiment with is a conventional medium-range missile, and the direction of the attack is in the target area in the distance."

"The accuracy of the missile is already very high, and the normal deviation does not exceed twenty meters."

"But rest assured, the missile carries an empty warhead, which is filled with sand and soil, and will not explode, even if there is an accident in the experiment, it will not threaten safety."

Wang Hao listened and nodded, he was really a little worried that there would be a deviation, and as a result, a missile exploded next to him.

That would be miserable.

When he returned to the experimental base, it was already noon, and Wang Hao quickly solved lunch, and it was almost time for the experiment.

He was placed on a hilltop, in a cave next to it, with some equipment and several screens, apparently dedicated to observing missile experiments.

Wang Hao stood on the top of the mountain.

Zheng Guofeng stood next to him and said, "This place is about twenty kilometers away from the shooting range. The weather is very good today, and if the experiment is successful and the missile is not intercepted, we can see it when it falls."

"Then I'm really looking forward to it." Wang Hao smiled, "I've never seen a real missile strike."

"You can see it clearly this time."

Zheng Guofeng went to get busy after speaking, the orbit change jet is the result of the 137 Institute, of course he will hope for the experimental results, especially invited Wang Hao to come to watch, it would be too embarrassing to fail.

He still has some faith.

They have already conducted two experiments and achieved certain results, but the final accuracy is a little worse.

This time, the control code has been corrected, and I hope that the accuracy can be improved a bit.

Soon.

It was already one o'clock, and the commander could already be heard shouting, "Ready!"

「3、2、1……」

"Launch!"

The commander issued the order for the experimental missile to be officially launched.

Medium-range missiles have many advantages, including rapid launch, rapid strike, and difficulty in interception, and it generally takes only 10 minutes from launch to concentrating on the target.

The flight time of the missile for this experiment was only 13 minutes.

Wang Hao has been waiting in place, looking at the sky from time to time, a blue sky and white clouds, coupled with the endless mountain scenery, it gives people a refreshing feeling.

In constant anticipation, I heard a sudden sound.

In the distance, sparks were visible to the naked eye, and the anti-aircraft missile was officially activated, and the missile's tail fell with white smoke and flew into the air.

Zhao Xingli, who was next to him, also explained, "The automatic warning of the air defense missile is 25 kilometers high, and we can't see it."

Wang Hao was a little regretful when he heard this.

Soon.

I remembered a noisy sound in my ears, a small black dot through the clouds, quickly falling to the left, but just looking at the direction of the fall, it was obviously not a shooting range.

The small black dot was still slowly correcting its direction, but it passed high overhead, and a faint collision sound was heard from behind for a long time.

Wang Hao was completely stunned, and then felt a little scared in his heart.

Although the missile hit a long distance from itself, it was only high overhead.

But it's still dangerous!

Zhao Xingli had already reacted, he looked at the command base with a dark face, and was very embarrassed when he turned his head and Wang Hao about the facts.

There is no doubt that the experiment failed!

The missile did complete the anti-interception work and was not hit by an anti-aircraft missile, but apparently the final hit position, and the deviation from the target was even several

Ten kilometers.

This can no longer be said to be a deviation, it is completely out of the normal trajectory.

A group of people walked up behind him.

Zheng Guofeng rushed to the front at a trot, and said with an embarrassed face, "The anti-interception has been achieved, but I don't know what's going on, the deviation is too big."

Zhao Xingli tugged at the corners of his mouth and couldn't help but say, "Can that still be said to be a deviation? Lao Zheng, this is a failure!"

"Failed, or is it a problem with calculations......

In fact, a failure is not a big deal, after all, the orbit change jet is a completely new device, and it is an auxiliary device for missile anti-interception, from research and development to technical maturity, it will definitely take a long time, and it will also go through many experiments.

But the most important thing is that the deviation is too much, it can be said that the experiment failed, and it happened in front of Wang Hao's eyes.

For this experiment, whether it is the 137 Institute or the Third Aerospace Industry Zone, they are very confident in this experiment, and because of this, Wang Hao was invited to watch, but the result was a huge failure.

That's where the awkward part begins.

Wang Hao felt a little scared just now, but at least he was safe now, and he still smiled, "Anyway, even if I saw a missile strike, I didn't run in vain."

Zheng Guofeng suddenly became even more embarrassed.

The experiment failed.

A group of people returned to the base, discussing experiments on the way.

Zheng Guofeng kept saying, "It must be related to computing."

"We fixed the calculation last time, but we didn't expect this to happen."

"The previous deviation was still a bit large, and the highest accuracy was also deviated by more than 50 meters, but this time it was really strange, and the direct deviation was dozens of kilometers."

Zhao Xingli emphasized again, "Lao Zheng, that's not a deviation."

Zheng Guofeng's face was flushed when he was said, and he could only spit out two words in the end, "Okay."

After returning to the experimental base, Zheng Guofeng didn't care about the problem of losing face, he quickly pulled Wang Hao to talk about the calculation problem.

The mathematical work done by Wang Hao pointed out the main direction of a missile correction, but when it really involves application, there is still a lot of content that needs to be calculated.

For example, port force control.

The power of the jet is supported by high-pressure gas combustion, and the size of the jet port determines the power manufactured.

In addition, the power generated by the jet port is also related to the path of the missile, and it also involves a direction control.

The calculations involved are extremely complex, and they put most of the work into mathematical calculations.

These mathematical calculations are also translated into code, so that the electronic equipment carried by the orbit change ejector can be combined with the radar data to automatically make calculation control.

Zheng Guofeng pulled Wang Hao and talked carefully, and also said that he wrote their overall design and detailed calculation methods.

Wang Hao listened patiently.

He found that one of the most complex and problematic areas was the direction control and the other was the jet size control.

However, the most uncertain thing is still the missile-related calculations, which involve the NS equation that needs to be approximated.

"Computers make approximate calculations of equations, but sometimes, there can be problems with deviations that are too large."

"Our calculations are not as rigorous, especially when it comes to direction correction, which is more likely to cause problems."

"This question determines the final accuracy."

"We've done a few experiments before, and we've come to the conclusion that the accuracy of the missile will definitely be affected."

"We wanted to improve accuracy and reduce impact, but we ......

Zheng Guofeng shook his head as he spoke, "There is still a problem with the calculation method, it is too complicated", he felt that the explanation was not clear, and took out a blank piece of paper to write three sets of equations, "It's like this equation, you have to do an approximate calculation automatically, and the resulting values sometimes have a big deviation."

Wang Hao picked up the blank paper and looked at the three sets of equations carefully, stunned

"That's the equation? Isn't it easy?"

「…… Huh?"

Zheng Guofeng was stunned when he heard this.

The others next to him were also stunned, similar to the automatic calculation of equations, stumped 137 institutes, even 136 institutes, and other research institutions under the aerospace industry.

They have been bothered by this problem for months, even more than a year, and it can be said that since they started researching, they have been bothered by the problem of automatic approximation calculation, and they have been constantly revising the background calculation code until now.

The result is to Wang Hao......

Very simple?

……

Wang Hao really thinks it's very simple, because it's just some partial differential equations.

After completing the study of the NS equation, he can be said to be the top in this field, and no other scholar can compare.

Although the equation seemed complicated, the first time he saw Fang Cheng, he had already thought of several ways to do approximate calculations, and each of them had a very high approximation.

In addition, he has done two computer projects with the approximation of the NS equation as the core, and he also knows what kind of way to make the computer's calculation closest to the real solution.

So he thought it was very simple.

After that, Wang Hao briefly explained and talked about the several projects he had done at hand, "Although there are differences in the equations, the calculation methods can still be referenced."

"I'm not sure what the best calculation is, but it's not that hard to solve."

Zhao Xingli's eyes lit up, and he immediately said, "Otherwise, Academician Wang, we will cooperate on the project, you will help us design a calculation method, and we will provide the funds......

"Not really."

"Huh?" Zhao Xingli was a little puzzled.

Zheng Guofeng thought that Wang Hao was unwilling to help, so he immediately said in a pleading tone, "Academician Wang, we have been troubled by this problem for a long time, can you ......help?"

Wang Hao said, "Professor Zheng, you misunderstood me, it's not that I don't want to help, but I don't need to do any projects."

"It's a very simple problem, I can solve it by researching it, and I don't need to go back and figure it out."

Zheng Guofeng was stunned again.

Zhao Xingli was also dumbfounded, "Academician Wang, you're not joking, are you?"

Wang Hao shook his head and said, "Can I joke about this kind of question? Otherwise, I'll think about it today, and I'll talk to you tomorrow morning."

"When the time comes, let's study it together."

「……」
