Into Unscientific

After all four modules are fully correlated derivation.

Fifth Master Qian immediately gathered the documents in his hands together and began to organize deeper calculations.

after all

The principle design of the missile is one thing, and the derivation of specific parameters is another.

In terms of parameter calculation, another inhuman support must be introduced, that is,

computer.

And to this point.

Members of the liaison team who had been only able to serve as spectators and barely beat the crowd before, finally had a place to play:

They need to encrypt various parameters that need to be completed by the computer, and then send it to the capital thousands of kilometers away.

Indeed.

This approach is very troublesome, and the time for data encryption and decryption will greatly affect the computing efficiency.

It is not an exaggeration to say.

With such a round-trip encryption and decryption time, the efficiency of the entire derivation process will be reduced by at least 50%, and even more.

But there is no way.

This is a time cost that must be paid.

Because it is different from the previous weather data.

The data collected by the weather Doppler radar has no confidentiality meaning, nothing more than wind speed, air pressure and the like.

Even if these data were intercepted by the lurking enemy agents across the sea, it would not matter. After all, there are too many items that need to report meteorological parameters these years.

But the missile parameters are different.

Not to mention that after the missile parameters are intercepted across the sea, will the secret that the rabbits are engaged in nuclear weapons be exposed.

Just the existence of the Zhuxian Sword Formation itself is enough to startle some people—it may seem like nothing in later generations, but it is a blow to the dimensionality reduction level in these years.

What will happen to a country, especially a big country, after it acquires technology beyond the times, the answer has already been given in "Transformers".

So whatever.

The parameters in the missile derivation process must be kept strictly confidential, even at the expense of doubling the price.

"Director Qian, our plan is as follows."

This moment.

in a room.

The team leader of the Liaison Department, Wang Zhicheng, was standing next to Fifth Division Qian, pointing to the liaison officers who were about to compile the code, and said:

"Director Qian, didn't the base conduct a meteorological data collection in the name of mineral vein detection before? This so-called 'mine prospecting' operation has been going on recently."

"So after repeated discussions with comrades from the Communications Department and the Secrets Department, everyone finally decided to use the composition of the ore as the cipher text, and use it to communicate with the capital."

Hearing what Wang Cheng said.

Fifth Master Qian pondered for a moment, then nodded lightly:

"very good."

Smart students should remember.

Before Xu Yun came up with weather Doppler radar technology.

The base mainly uses the manpower method of dispatching sideline teams to collect meteorological data, and receives the data in a grid, so as to cooperate with the hygrometer to calculate.

At that time, the sideline team went out to the outside world. That is, the reason for the major units in Xihai Province was that the mine needed to conduct a large-scale exploration of ore veins.

Although the data collected by this method was of no use in the end, Ye Duzheng and his calculations failed miserably.

But this behavior itself still confuses the enemy agents very well.

After all, it is very common for rabbits to look for all kinds of stones these days, just as it is common for rabbits to love building in later generations.

And this time.

The base took advantage of this action again.

In the past few days, in order to prevent the prospecting operation from ending too abruptly, the base will still send many people to set up a maze every day.

So now this layer of skin is completely reasonable to pick up, without any haste.

The second reason is that the major components of the ore have fixed names, and can be reflected by various values.

For example, how much calcium compound content, how much iron compound content and so on.

Although the difficulty is still not low.

But at least it is much easier than encrypting numbers into full text similar to ordinary letters.

Immediately afterwards.

Wang Chengcheng took out another code book with a relatively simple appearance from the table, and handed it to Fifth Master Qian:

"Director Qian, this is the cipherbook we made in a hurry, please take a look at it."

But Fifth Master Qian waved his hand and refused:

"No need, comrade."

"Since the leaders of the base have agreed that you use this set of notebooks to participate in today's work, it naturally shows that your codes meet the requirements and are reliable."

"That's why I don't comment at random if I only have a half bucket of water in cryptography. If you are ready, you can start directly."

"The next step is the 'battlefield' of your liaison team. Comrades, you have a heavy burden on your shoulders."

Faced with Wang Cheng's approach, Fifth Division Qian chose, as always, for laymen not to interfere with insiders' affairs.

This can also be regarded as Qian Wushi's philosophy of dealing with things in his life, which he followed until the last moment of his life.

As for the "one cipher class" mentioned by Qian Wushi, it is also an interesting story that he has been talking about since then:

At that time, Master Qian Wu was still studying for a Ph.D. at Caltech, and one day he was going to take a class in applied mathematics.

So then.

The fifth division Qian rushed to the classroom early, and since he had more time, he started the problem by himself.

As time went on, other students gradually began to sit beside him.

As a result, Fifth Teacher Qian found out when the class bell rang.

He doesn't know the classmates around him at all, and the teacher on the podium is also a stranger.

However, Fifth Division Qian was sitting in the first row of top students at that time - the Huaxia international students basically liked to sit in the first row or two.

So in desperation.

He could only listen to a section on ciphers abruptly. Or code science.

And that math class became the only absence in Qian Wushi's study abroad career.

alright.

The line of sight returns to reality.

Seeing that Fifth Master Qian was so open-minded, he didn't point fingers.

Wang Chengcheng, who was dealing with the Fifth Master Qian for the first time, was surprised and delighted, and at the same time, a surge of motivation quickly surged in his heart:

"Director Qian, please rest assured, our team promises to complete the task!"

Say it.

He turned his head and looked at the liaison officers beside him who had already settled down, and said loudly:

"Comrades, everyone must have heard Director Qian's words. Our task this time is very difficult!"

"So please be careful and don't make mistakes, because every key you press may have a bearing on the overall situation."

"Okay, let's start now!"

The room where Wang Chengcheng and Fifth Master Qian lived was located at the lower right of the [A]-shaped layout, and a telegraph machine had been installed inside.

Therefore, following the order of the king.

Several telegraph operators who had already held the earphones in their hands suddenly looked serious, and put the earphones on their heads in unison.

After a while.

Didi--

In an instant, there was a dense sound of electric keys in the room.

About five more minutes passed.

The first encrypted data was sent to the capital.

at the same time.

capital.

Institute of Computer Science, Chinese Academy of Sciences.

A room for sending and receiving telegrams.

Wu Jikang, who was the deputy director of the Computer Institute at that time, still stayed by the transceiver in person today, and at the same time there was another man standing beside him.

This person has a pair of protruding ears, a thin face and a dark face.

At the same time, the two eyebrows drooped obliquely, showing a word '囧'.

After a while.

Wu Jikang glanced at the watch in his hand, and said to the man with protruding ears:

"Comrade Wenji, Comrade Fifth Division has already exceeded the expected time by ten minutes. Why don't you go to the next room to rest?"

"You just rushed to the capital from Chang'an, and your body hasn't recovered yet. There's no need to force yourself here."

"Anyway, I'm here waiting for the transceiver, you can rest assured that there will be no omissions in terms of news."

The man named Wenji's full name is Qian Wenji, and he shook his head resolutely when he heard the words:

"Old Wu, there is no need. I know Comrade Fifth Division very well. He is a very committed person."

"Since he's set the time, I'm sure he won't procrastinate for too long—he's not one of those people who write novels in newspapers and always take a week or two off."

"."

Hearing Qian Wenji's words.

Wu Jikang opened his mouth, as if he still wanted to persuade:

"But you just finished an operation"

beep beep——

As a result, Wu Jikang didn't finish his sentence.

The telegraph next to the two of them beeped in a hurry.

See this situation.

Qian Wenji jumped up from the chair in an instant, and ran to the radio station in one step.

I saw him carefully staring at the slowly emerging note for a while, and then suddenly waved to Wu Jikang:

"Old Wu, do me a favor, I fmd can't understand these things."

Wu Jikang:

"."

After a while.

Wu Jikang sighed quietly, walked quickly to Qian Wenji's side, picked up a small notebook and began to translate:

"The limonite sample of 6.73 kilograms of limonite refers to the radius of the precursor. The single digit must be multiplied by 8 and then divided by two, which is 24"

"One digit after the decimal point is multiplied by 1.53 and then divided by 6, which represents the descending range of the generic function, and it is accurate to four digits after the decimal point"

"The third is."

A few minutes later.

Wu Jikang put down his pen, rubbed his sore eye sockets, and said:

"Comrade Wenji, here, the translation is ready."

"Thanks."

Qian Wenji immediately took the small book and flipped through it quickly:

"Gas outflow 0.5m/h"

"The six groups of floating mean values ​​1.55, 1.33, and 1.47 must be calculated."

"The delivery speed is estimated to be six-figure calculations, and our computers should be able to afford it."

Wu Jikang stood aside and did not urge Qian Wenji.

After all, today the Computer Institute has set up five receiving points, which are located in separate rooms, and the information received by each group is also different.

They are slower here, and other points will definitely bring another set of data to the computing table for import.

This import process will take a lot of time, so there will be no impact on efficiency because Qian Wenji looks at the data.

after awhile.

Qian Wenji, who had read it several times, suddenly frowned slightly.

Strange

It seems that some data are different from what was agreed, and the discrepancy is still relatively large?

Then he closed the notebook without showing any doubts, and said to Wu Jikang:

"Old Wu, let's go to the computing table for numerical simulation."

Wu Jikang nodded:

"no problem."

Then under the leadership of Wu Jikang.

The two came to the computing desk on the third floor of the computer institute.

as expected.

When the two entered the room.

There are already two comrades from other receiving points on the side of the operating table holding small notebooks, guiding the operators to enter data.

Then about ten minutes passed.

A girl with neat short hair raised her hand and asked around:

"The two groups are calculated, who will come next?"

Seeing this, Wu Jikang brought Qian Wenji to the girl's side, handed over the notebook, and said:

"Xiao Lin, I've worked so hard on you to import these data."

"okay!"

The girl named Xiao Lin seemed to be very outgoing. After meeting Wu Jikang, the "boss", she was not restrained, and quickly took the notebook to enter the data.

clack clatter——

mentioned earlier.

Although computers these days do not have FLUENT or STAR-CCM+, they still have the basic composition ability.

For example, if you input the numbers [length 4 cm] and [width 3 cm], a corresponding rectangular pattern will be automatically generated on the screen.

The same is true for missile design drawings, and even arcs can still be generated-although the resolution and fineness are not so high.

So soon.

In front of Qian Wenji, Wu Jikang and others, an icon outlined by simple lines appeared.

And the moment I saw this schematic diagram.

Qian Wenji sighed lightly, and blurted out:

"The combat unit is one meter long? Why is it shorter than that Wu Dalang in Pandora?"

Say it.

He leaned over to the computer and looked at other data:

"The working cavity is 40 cm, but how can it have the power to fly?"

The voice just fell.

Qian Wenji's eyes noticed a structure under the missile again, and his tone suddenly changed from ordinary curiosity to shock:

"This is... a waverider?"

Mentioned earlier.

In today's entire project, the Capital Institute of Computer Science is responsible for a large amount of data simulation.

Because these data are highly specialized.

Therefore, there must be a professional in charge of the computer institute, who is personally responsible for assisting in the simulation of missile data.

In a sense.

Equivalent to the role of a special executive advisor.

After repeated discussions in the organization, the superior department finally selected Qian Wenji to take charge of this task.

Although Qian Wenji had just undergone gallbladder surgery, it was only a week after the operation—note, it was not a week after being discharged from the hospital, but a week after the operation.

But the superior still insisted on this choice.

no way.

Take a look at the current field of missile research.

Except for those team members taken away by Qian Wushi, only Qian Wenji could take on this important task-the others were either inexperienced or not in the capital.

So the organization is really not about squeezing Qian Wenji, but that there is no one to choose from.

Qian Wenji didn't say a word after receiving the somewhat vague notice from his superiors, and immediately took the early morning train from Chang'an to the capital.

Of course.

For Qian Wenji himself, the fact that he just got out of the hospital is not the point.

What he really cares about is.

What happened to Fifth Master Qian?

To know.

According to the notice he received earlier.

The "Zhuxianjian" team plans to conduct missile deduction around the direction of the center of mass today. The preset length of the missile should be about 1.5-2 meters.

It turns out that the current missile has not only shrunk to 1 meter, but also designed a unique waverider-like structure?

Think here.

Qian Wenji couldn't help but took a deep breath, and began to look at the data seriously.

“\u0026amp;amp;amp; @#ξ^O^￥.”

As the chief designer of China's first generation of surface-to-air missiles and the top military engineer who will design Hongqi No. 1 and No. 2 in the future, there is no need to question Qian Wenji's ability.

So after a few minutes.

A sense of enlightenment appeared in Qian Wenji's eyes, and he touched his chin lightly:

"I see."

See this situation.

Wu Jikang, who was always a little confused, couldn't help asking curiously:

"Director Qian, what's the matter?"

"Well, there was an accident."

Qian Wenji hummed subconsciously.

Then he thought that Wu Jikang and the operators around him had a high level of confidentiality, so he directly explained:

"There were some accidents in the design process of the missile, and there was a problem with the parameters of the spiral body—roughly, the body length of the missile was much lower than our expectations, and all the data had to be re-derived."

"However, judging from the design drawings at Lao Qian's side, this problem has been solved by their smooth optimization, so it's safe to say."

Wu Jikang still nodded in a daze:

"Oh, that's it, it's quite simple, I understand."

Qian Wenji didn't pay attention to Wu Jikang's perfunctory, at this moment two thoughts quietly popped up in his mind.

the first thought was

Could it be that Qian Wushi Longchang enlightened?

To know.

Although Qian Wushi is the proponent of the waverider technology, this technology has never seen the dawn of implementation.

Let alone domestic.

Even Mao Xiong and Haidian are at a loss for this technology, and Haidian even listed it as a front-end technology that can only be broken through in the next 50 years.

As a result, as soon as Fifth Division Qian went to Base 221, they suddenly came up with such a waverider missile?

indeed.

There is still a distance of 108,000 miles between this kind of missile and the real waverider warhead.

The size, structure, and flight length of the two are completely different.

But no matter how far this distance is, it will be much, much brighter than the darkness before.

Of course.

This thought only flashed in Qian Wenji's mind, and then was replaced by another thought:

Some of the ideas of this missile seem to be like maybe for the project he is currently working on.

A little help?

This moment.

Thousands of kilometers away.

Xu Yun didn't know that the waverider warhead designed by himself and Qian Wushi would make the style of a certain surface-to-air missile of the rabbits crooked to Andromeda in the future.

Right now, he and Fifth Master Qian are drooping their heads with obedient faces, bearing the crazy diss of Old Wang in front of them together:

"Xiao Han, old Qian, what the fuck are you talking about?"

"Do you want the Zhuxian platform to fly another 10,000 meters? 40,000 meters above the ground? And the higher the better?"

Looking at Mr. Wang with a face of "You Timo are teasing me", Fifth Master Qian couldn't help but scratched his head with an awkward smile:

"Yaoping, actually it doesn't need to be that high, nine thousand five hundred meters is fine."

"."

At this moment, Mr. Wang could clearly feel that the veins on his forehead were twitching:

"Is there any difference? Why don't you say nine kilometers?"

"Nine kilometers is fine!"

Fifth Master Qian's tone subconsciously mentioned it, but after seeing Mr. Wang's eyes that seemed to kill him, he immediately hesitated:

"Yaoping, just do me a favor, this is all for the country."

"Back then we lived next door in the dormitory, and I didn't say anything when you came to my house every day to have dinner—although the food was cooked by Ah Ying, I washed the rice and vegetables, didn't I?"

"So if you round it up, you still owe me a favor, am I right?"

Mr. Wang:

"."

After a while.

Elder Wang's chest heaved a few more times, then he waved his hand like chasing away flies, and said:

"It's okay, you won."

"Didn't I go to rub you for a few meals at the beginning, but now it's like a donkey, and you come to grab a couple of hairs if you have nothing to do."

"Fortunately, I didn't borrow money from you at the beginning, otherwise I guess I would have to sign a contract of sale at this time?"

Xu Yun:

"."

Do not know why.

He always felt that in the conversations of everyone in the base recently, the frequency of the word donkey seems to have gradually increased a lot

Is this painting style going to develop towards Dingxianglou?

Of course.

Most of the displeasure on Wang Lao's face was faked.

After all, as a member of the aerospace program.

Although Mr. Wang doesn't know the ballistic design of missiles, he has made a lot of achievements in missile launching based on his long-term accumulation of experience.

not long ago.

After hearing the news that Fifth Master Qian who brought Xu Yun to the door said [the length of the missile has been shortened to one meter].

Wang Lao didn't need Fifth Master Qian to speak, he immediately realized one thing:

The height of Zhuxian Sword Formation will definitely be raised again.

At the same time, it is compared with the material problem of the airship.

In the case of both belonging to the stratosphere, the non-capsule module is the most in need of optimization.

After all, in addition to the elastic layer of donkey hair, the most critical gas exchange membrane of the capsule was developed for enriching uranium.

Its defect mainly lies in the accuracy error caused by the equipment being tampered with, and the strength is not a problem of half a dime.

Let alone 40,000 meters in terms of environmental load, 400,000 meters is not difficult-the load of enriched uranium is roughly equivalent to the pressure difference between the altitude at 400,000 meters and conventional gas.

But the structure is different.

for example.

Airship hull thickness ratio.

This thing has a great impact on the drag coefficient of the airship, especially after the thickness ratio exceeds 0.35, the drag coefficient increases significantly.

The resistance here is not only parallel resistance, but also upward resistance.

That is to say, if you want to fly to an altitude of 40,000 meters, the thickness rate must be modified.

In this way.

The structure of the entire airship and the gas flow between several airbags must be recalculated.

The only thing that can be called lucky is.

There is no need to overthrow and modify the designs of Mr. Wang and the others in the first few days, after all, those are the foundation of everything.

No matter the thickness ratio is 0.2 or 0.9.

The basic modules they need, that is, the alloy-like structure, remain unchanged.

That is to say, in the worst case, the entire group will probably waste today's efficiency.

Think here.

Mr. Wang gave Fifth Master Qian a blank look again, and spread his hands angrily:

"Okay, bring your parameters."

Seeing this, Fifth Master Qian chuckled, took out a document from his briefcase and handed it to Mr. Wang:

"Yao Ping, I'll trouble you this time. After I'm done, I'll take you to steal cough cough and borrow Lao Guo's liquor!"

"This kid still thinks I don't know. I have already found out where he hides the wine."

Elder Wang curled his lips and waved at the two of them:

"Okay, come with me to the group."

Say it.

Mr. Wang took the initiative to walk behind Xu Yun, and pushed Xu Yun's wheelchair for Fifth Master Qian—don't look at Mr. Wang's ruthless words, he had already noticed that Fifth Master Qian was panting for breath because of pushing the wheelchair situation.

"."

Feel the strength and steady breathing of the middle-aged version of Wang Lao's cart behind him.

Xu Yun, who was sitting in a wheelchair, couldn't help feeling an inexplicable emotion in his heart.

This emotion is different from the excitement and honor when Fifth Master Qian pushed the wheelchair, and it is also mixed with some experiences of Xu Yun's later generations:

At that time, after the HKUST Dark Matter Conference ended.

In the Xichang satellite base.

He also pushed Wang Lao's wheelchair in the same way, and walked together on the path of the base, watching the afterglow of the setting sun together.

Unexpectedly, after entering the copy.

The person in the wheelchair turned into himself, and the person who pushed his switch turned into Wang Lao.

Coupled with Xu Yun's later exchange with Wang Lao in the hospital, Xu Yun's mood at this time is indeed quite delicate.

Is this cause and effect?

Reincarnation?

Or is it a coincidence?

But soon.

Xu Yun shook his head lightly to dispel this thought.

No matter what the truth is.

It would be nice to see a healthy Wang Lao.

Then under the guidance of Wang Lao.

Xu Yun and Qian Wushi quickly came to the office where the Killing Immortal Sword team was located.

It is different from the single building owned by Qian Wushi and his Zhu Xianjian group.

The office assigned by the Killing Immortal Sword team is located in the southeast corner of the 18th branch. It was originally a vacated iron warehouse.

The area of ​​the warehouse is very open, but due to the heat conduction of the iron sheet, the interior is very hot, with a conservative temperature of more than 30 degrees.

There is a very long rectangular table in the center of the warehouse. On the walls on both sides, there is a wire that seems to be brought in temporarily. The end of the wire is connected to two electric fans.

The two electric fans were a little worn out, and even the outermost covers were not complete, and they looked bumpy.

In addition, perhaps because they were worried that the wind would blow away the manuscript paper, Mr. Wang and the others set the wind speed of the fan very slowly.

So the fan creaks louder.

This moment.

Zhang Gongding, Zhou Shaoping and Zheng Tao, who Xu Yun was familiar with, were all helping out.

Among them, Zheng Tao and Xu Yun are not very familiar with him, and he is not sure what direction he is in charge of-in fact, Xu Yun has always felt that Zheng Tao is like a pseudonym.

But Zhang Gongding and Zhou Shaoping

Definitely assisting with math calculations.

After all, both of their majors are theoretical physics, which is completely different from the applied physics of designing airships.

Then Mr. Wang walked to a small blackboard and a 1.5X1 wooden table next to the blackboard.

Old Wang coughed lightly and said to everyone:

"Okay, comrades, stop what you're doing first."

Click, click.

Soon there were several sounds of pens being put on the table, and the sound of rustling paper disappeared.

"."

Then Wang Lao looked around and said just now:

"Comrades, now I have some bad news to tell you, that is"

"Except for the scaffolding structure of the 'Zhuxian Platform', all other modules have to be overthrown and rebuilt."

"?!"

I heard this.

Everyone at the scene was startled for a moment, and then Lian San said:

"Director Wang, what happened?"

"Teacher, why? Everyone has worked hard and calculated for a long time."

"Director Wang, is there something wrong with the parameters of any link?"

"Teacher Wong"

Of course.

Not everyone asked questions, either.

For example, some people have a relatively dull personality and don't like to express their inner thoughts.

For example, Xu Yun saw a girl with a dark complexion and a single ponytail. After hearing the words, she silently took out a new piece of calculation paper and pressed it onto the page that was originally full of values.

Others have sharper minds.

For example, Zheng Tao and Zhou Shaoping turned their attention to Xu Yun and Fifth Master Qian at this moment, with thoughtful expressions on their faces.

It is clear.

They have guessed something.

After a while.

After the voice of inquiry subsided consciously, Wang Laofang said slowly:

"I'm sorry, comrades."

"Although I really want to tell you the real reason, due to the confidentiality regulations of the Zhuxian project, I can't explain the specific situation to you in detail now-because it involves some core projects."

"What I can tell you now is that there were some accidents in Jade Immortal Sword, and the problem has been solved after optimization and calculation, but..."

"Correspondingly, the stagnation altitude of the airship we designed must also be increased"

Speaking of which.

Elder Wang glanced at Fifth Master Qian at the side.

A number slowly burst out:

"Fifteen kilometers."
