The military-industrial scientific research system of the academic master

Chapter 1339 Comrades, yes, we have three types of propellants as strong as this...

It turns out that the shock brought by numerical weirdness is often the simplest, but the most direct.

After several minutes, Shen Fangzhong finally came back to his senses.

However, before he could speak, he heard the voice of Li Jianqiang next to him:

"So this is how you achieve dual-pulse power... Directly control the working parameters of solid propellants, without adding an additional compartment or layer to the missile structure?"

For a long time, the uncontrollability of solid fuels was basically the underlying logic of the entire rocket power field.

Just like Newton's mechanics of motion to 19th century physics.

Therefore, the moment he saw the material just now, he even felt that his worldview was about to collapse.

Just like a physicist who first saw Planck's black body formula and realized that "the world may be discontinuous."

"Of course not..."

Faced with this question, Lin Chenggang gave a very straightforward negative answer:

"About a dozen years ago, anti-ship missiles were still mainly rocket-powered... At that time, in order to increase the range, we once considered the kind of compartment design you mentioned, allowing the missile to cruise at a low speed in the middle stage and then sprint at a high speed."

"At that time, I had just started working and presided over the design of a soft isolation device made of two layers of rubber wrapped in cork. The rubber fits tightly with the powder column, and the igniter and the Ⅱ pulse powder column are connected together... But after testing, it was found that the stability was too poor. There is about a 60% probability that the Ⅱ pulse will start burning immediately after the I pulse, and there is no way to put it into practical use."

Even in the relatively wild period of the development of China's military industry, the pursuit of advanced concepts and technologies has not been abandoned.

Even the dual-pulse power, which seemed very high-end at the time, was not only studied by the Air Force Equipment Research Institute.

And the conclusions of both sides are basically similar.

This is why Lin Chenggang was able to think of the modification method of adding electrosensitive materials to the CT series propellants during the development of them.

While Li Jianqiang was still digesting this information, Shen Fangzhong took over the conversation again:

"In your opinion, is it possible to use the same technology on the long-range air defense missiles equipped by the Air Force Ground-to-Air Missile Force?"

Lin Chenggang smiled mysteriously, and then took out the reply issued to him by the Construction Committee this morning:

"In fact, I was just about to go to you..."

Shen Fangzhong lowered his head and quickly scanned the contents of the red-headed document.

He quickly caught the key words:

"Suggested by Academician Chang?"

Obviously, the smoothness of the development of things far exceeded his expectations.

Originally, when he saw Lin Chenggang, he was still worried that the other party would not be able to spare enough energy to coordinate with him in a short period of time.

It turned out to be completely over-concerned.

"Yes."

Lin Chenggang nodded:

"But my work relationship still needs to be here, and I can only participate in your project as a consultant..."

For Shen Fangzhong, this little thing is not a request at all:

"We can agree to all these organizational requirements, and the funds and manpower will be guaranteed in place first."

He directly made a big promise:

"When can we start docking at the earliest?"

This posture made Lin Chenggang on the opposite side stunned.

I didn't expect the other party to be so urgent.

"It may take a while, and there are still some hidden dangers in the strength of the grain column after the charge is formed."

There was a little embarrassment in his tone, so he added:

"But we are already cooperating with the Torch Laboratory to conduct theoretical calculations on the work process of the CTK series propellants to find out the root cause of the problem."

"With their level, it shouldn't take too long..."

As if to verify the correctness of this sentence.

Before the last word of Lin Chenggang fell completely, the red phone on the upper left corner of the desk rang loudly, interrupting the conversation between the three people.

He leaned over to take a look, then stretched out his hand and made a gesture to keep quiet.

"Hello, Professor Li..."

The call was naturally from the Torch Laboratory.

Since Chang Haonan has been stationed in Huairou Science City recently, Li Yabo has always been in contact with Lin Chenggang.

However, this time, a more mature voice sounded from the other end of the receiver:

"It's me, Chang Haonan."

"Academician Chang?"

Lin Chenggang's body reacted faster than his brain. Although there was a telephone line between them, he stood up straight:

"How come..."

"The situation of your system is a bit interesting. It just so happens that there is not much going on in Huairou these two days, so I took the time to come and take a look."

There was a hint of smile in Chang Haonan's voice:

"It's just a coincidence that the results came out..."

Lin Chenggang has already developed a strong resistance to words such as "coincidence", "luck", and "by the way" from Chang Haonan's mouth, and he doesn't even believe a punctuation mark.

There must be some problem that Li Yabo can't solve, so he asked his mentor for support.

It was just that this was part of the internal play of the master, so he couldn't ask too much.

"Then I'll go right over..."

There is no mistake in the content of the first post, just look at the 6-9 book forum!

Being preparing to end the call, Lin Chenggang suddenly glanced at Shen Fangzhong and Li Jianqiang, who was aggressive on the opposite side of the desk:

"Academician Chang, the Second Hospital, who is responsible for the development of the 9 model of the Red Flag 9, and the Director Li Jianqiang of the Air Force Institute of Equipment Research, is just on my side, you see ..."

He said that this is the case, and Chang Haonan will naturally not refuse:

"Come here together."

Nympho

Because of the tight time, Chang Haonan even had no time to sort out a complete analysis report, but received a party directly in the underground machine room of the computing center.

"Because it is not an ideal solution system, and there is still phase change during the work process, the entire calculation is more complicated, involving a lot of theoretical knowledge of physical chemistry, so I will say a long say."

He said that the surface simulation diagram of about 100 molecular thickness was called:

"The second ignition failure actually involves two independent reasons, so it is normal for Comrade Cheng Gang to analyze the conclusion from the macro work parameters alone."

Lin Chenggang was a little unclear for a while, should he be pleased whether he was for this.

Fortunately, Chang Haonan didn't give him too much tangled time, so he picked up a pen from the table next to him, pointing to a position on the picture:

"In order to ensure the control effect obviously, you use three -dimensional polyethylene alcohol as an adhesive to improve the resistance of the entire system, so that it can only achieve high -speed combustion when it meets two conditions of high voltage and high voltage and high voltage. Adjusting, it should be said that the idea is relatively clear. "" "" "" "" "" "" "" "

Just after listening to the first sentence of the theme part, Lin Chenggang had already stood on the spot-

The content of the other party is almost consistent with the journey of their hearts at the time of development.

He had not disclosed with anyone before.

"But this system is not only sensitive to voltage, but also sensitive to heat. It is continuously exposed to high temperature flames and chemical decomposition due to overheating. Therefore, in your test, the success rate of the next ignition of the cooling state is 100%. And the second ignition is easy to fail, which is why you can observe the cracked pillars observed in the wreckage. "

Lin Chenggang took a deep breath and revealed a sudden realization:

"No wonder ..."

After a few minutes, Chang Haonan opened another calculation document and continued to introduce:

"On the other hand, the combustion characteristics and electrical characteristics of tungsten are indeed very good, but the density reaches 19.35 ... According to my calculation results, in the process of mixed mixing agent components or plasma static and solidified, there will probably be there. 70%of tungsten powder is settled in a 25%area at the bottom of the plasma mixed fluid, which can easily lead to internal defects of the pillar column. "

If the first half of the content also allows the three to hear the clouds in the clouds, then the second half is relatively easy to understand.

Shen Fang's loyalty face is serious:

"Does this mean that the larger the volume of the pillar, the larger the hidden dangers left?"

The volume of the Red Flag 9 air defense bomb is more than a few times the short -range bullets used by the Army. If it is said, as Chang Haonan said, the application prospect is not very optimistic.

"This is inevitable."

The latter nodded:

"In fact, even if the problem of tungsten powder is not considered, CTK-2 can only be burned by AC electricity at a small electrode spacing. For large-scale pillars, it is necessary to apply an additional coated conductor layer, which further reduces the stability of the system ..."

This conclusion makes Shen Fangzhong, who is looking forward to, is unavoidable to feel a little disappointed.

He just wanted to say something, but Chang Haonan turned around again and opened the first:

"In fact, Researcher Lin's thinking is already very successful."

"The base system of CTK-2 is not large, especially the choice of oxidation agent of nitrate nitrate is very in place. It only needs to replace the adhesive to a polyetterol with a high polymerization. While reducing the ignition power, it significantly improves the intensity of mechanics and relieves the softening of melting. "

Shen Fangzhong reached out and touched his chest.

This plot that has a big rise really makes him an old man who can't eat it.

Lin Chenggang looked at the results on the screen in front of him, and suddenly a little doubt the world:

"That tungsten powder ..."

"This is another thing I want to say, and the most interesting part of your system."

Chang Haonan answered with interest:

"You only need to adjust the type and process of metal additives, and you can start from the uniform base of CTK-2 to extend at least three different properties. It is suitable for the formula system on different occasions ..."
