In 1978, I was admitted to Harbin Institute of Technology

Chapter 193: Lack of high-energy explosives? Alumni whose achievements were plagiarized by the Americans must be invited back
"Principal, even if we use RDX to increase the explosive power and killing range, I'm afraid Jiangbei Machinery Factory will not agree."

Xie Wei reminded Li Rui.

Now he understood why in the history of his world, the Jiangbei Machinery Factory took a long time to develop the PF89 rocket launcher.

After the successful research and development, it took a lot of time to improve the design of the warhead for each model.

Lack of advanced high-powered explosives!

When Jiangbei Machinery Factory took on the research and development task, the troops required an anti-armor warhead, which had a greater demand for high-energy explosives.

"What do they disagree with?"

As soon as Li Rui finished speaking, he realized the problem and was stunned.

In the cooperation with Jiangbei Machinery Factory, Principal Li agreed to take 7% of the sales price, and the remaining % would be the production cost and profit of Jiangbei Machinery Factory.

The price supplied to the troops may be reduced, but the cost will increase significantly.

It is even possible that the Jiangbei Machinery Factory will lose its profits due to rising costs. How can they do that?

"How about trying mixed explosives?"

Xie Wei said tentatively, "It's too expensive to use all RDX. We can mix some TNT in RDX to reduce the cost, add some aluminum powder as a combustion aid and explosion aid, and use paraffin as a passivating agent..."

Aluminum-containing explosives are currently a cutting-edge topic internationally.

This formula was developed by the Australians, but was eventually installed by the Americans into the 3000-kilogram GBU-43, known as the mother of all bombs, and eventually used in the Afghanistan War.

As for how powerful it is, only Americans themselves know.

After all, the strength of the United States in that era was maintained by bragging. Even if it was really publicized, no one would know whether it was true or not.

Xie Wei just knew the general formula.

43.5% RDX, 29.3% TNT, 20.6% aluminum powder, 4.89% paraffin, and the remaining 1.71% is adhesive.

"The cost of RDX is not low!"

Zhai Xinguo looked worried.

The cost is too high, which will definitely affect the number of equipment.

"Let's first solve the problem of whether it exists or not. If it can be made, the warhead of the 40mm sniper grenade can also be equipped with this thing to increase its power..."

Xie Wei believes that first of all, we must solve whether there are any problems according to the needs, and then consider how to reduce costs.

In the military field, it is obviously inappropriate to give up using more powerful and advanced technologies during research simply because the cost is too high.

The mode of war will undergo tremendous changes with the development of science and technology. Xie Wei, who came from the future, knows very well that in the next hundred years, it is basically impossible for a nuclear war to occur as the Soviet Defense Minister, who has always opposed the construction of aircraft carriers, believes.

In Ustinov's view, the Soviet Union must be prepared for a nuclear war. After the outbreak of a nuclear war, industrial capacity and economic strength will decline severely. At this time, high-reliability and high-lethality weapons and equipment that can be produced under lower production conditions will be needed.

As a result, the Soviet Union had the MiG-23 that could be used as a disposable consumable, the MiG-3 with a Mach 25 engine installed in a stainless steel shell, the T-72 tank that retained super firepower to the maximum extent, reduced protection and production costs, and so on...

The Soviet military's thinking also had an impact on the country.

Many generals in the army also think so, and believe that as long as the weapons and equipment are powerful enough, cheap and can be deployed on a large scale, it will be fine.

The scale of the world's largest artillery force is very telling.

Xie Wei could understand why the leading cadres of the army thought this way.

He didn't expect that even Zhai Xinguo was affected.

The more advanced the technology, the greater the performance gap between equipment.

Once upon a time, when there was no J-10, faced with such advanced fighter jets as the F-22 whose performance was so high that it made people despair, the Air Force proposed the spirit of fighting with bayonets in the air: exchange 8 J-8IIs for one F-22.

The specific plan is extremely tragic: in a state of war, a large number of J-8 fighters rush towards the F-22 regardless of their lives, constantly getting closer, and use 8 J-8IIs to consume the ammunition carried by the F-22. When the opponent's ammunition is used up and they are close again, they naturally have an opportunity.

In order to create attack opportunities for their comrades, eight pilots who were trained by the country at great cost, rushed towards the enemy without giving up their lives.

How tragic!

However, after the Air Force had its own J-20, it discovered that the bayonet plan had no chance of being realized!
金头盔军演中，歼-20跟4代机的歼-10、歼-11、歼-15、歼-16交手，0:108！

In the United States’ Red Flag military exercise, the F-22 fought against other fourth-generation aircraft with a score of 1:144!

The generation gap means that the opponent basically has no ability to fight back.

This is also why the United States was so arrogant when China only had the J-20. After all, it had the F-22 and F-35 to compete.

When Ginkgo's sixth-generation aircraft came out, the Americans immediately became obedient. They began to experience the tragedy that the Chinese once experienced and planned to use 8 F-35s to create attack opportunities for the F-22.

Unfortunately, pilots in capitalist society who join the army for money do not have the self-sacrifice spirit of Chinese pilots.

While China's seventh-generation aircraft has been put into service, the American sixth-generation aircraft is still in the drawing board stage.

Without him.

There is no wind tunnel laboratory with a full-scale model of hypersonic speeds.

"There is no one or team researching explosives in the school right now."

Li Rui looked embarrassed.

Xie Wei glanced at him. The old man was really tight-lipped!
"How about taking Tang Long back? Is his project almost done?"

Xie Wei asked Li Rui tentatively.

After Tang Long left, there has been no news since then.

"Did Tang Long go to get explosives?"

Tang Daoxian asked in surprise.

He was the first student to leave the experimental class. No one knew where he went or what he was doing.

Li Rui glanced at Tang Daoxian, then glared at Xie Wei, "He is not available in the short term."

"How about you help me invite a senior student?"

Xie Wei had an idea and wondered if he could bring the guy who played with explosives to school.

"Oh? Who?"

Li Rui was curious. When Xie Wei wanted someone before, he only talked about the direction but didn't say who it was specifically. This made Li Rui afraid that he would be cheated if he went to the unit where he wanted to hire someone. He didn't know how much thought and effort he would have to put in.

It will be easy if there is a clear person.

"Senior Yu Yongzhong, who graduated from our school in applied chemistry before liberation, should now be working at the Dalian Institute of Physical Chemistry of the Chinese Academy of Sciences..."

When Xie Wei called him an alumnus, he was telling Li Rui that this person graduated from our school and he could play the emotional card.

He actually didn't know whether this explosives expert was currently at the Dalian Institute of Physical Chemistry or the Lanzhou Institute of Modern Chemistry. The only thing he knew was that in 1984, Professor Yu Yongzhong worked part-time as a doctoral supervisor at the Capital Institute of Technology, which had not yet been renamed Beijing Institute of Technology!

"Him? Liang Hongbin told you?"

Li Rui's words surprised Xie Wei, Zhai Xinguo and others.

"He went to the Lanzhou Institute of Modern Chemistry. But I'm worried that he won't want to come to school."

Xie Wei didn't know what Li Rui meant by this. Even though he was curious, he didn't want to ask in front of Tang Daoxian and the others.

He immediately said to Li Rui: "President, please tell Professor Yu that the school fully supports his research on improving the synthetic method of cage-type nitro compound structure..."

"Full force?"

Li Rui's mouth twitched, "Xie Wei, do you know how much this will cost?"

"School-enterprise run!"

Xie Wei was too lazy to pay attention to him.

The old guy had no idea how important what Professor Yu was researching was. Last year, Professor Yu synthesized a very distinctive cage-type nitro compound 979#, and published a paper on cage-structured single-element explosives in an international journal for the first time.

979# explosive has high energy density and high stability, but the detonation speed of this compound does not exceed that of Octogen.

Due to backward domestic equipment and lack of funds, Professor Yu had to wait until 84 when he became a doctoral supervisor at Capital Institute of Technology before he began researching cage-type nitro compounds again.

After discovering Professor Yu’s paper, the Americans directly used it as a basis to create the king of explosives, CL-20 (known as C-12 in China).

In Xie Wei's world, when this fact was made public, almost no one believed it. After all, in the eyes of those who regarded the United States as their father, the United States was advanced and China was backward, and China's technology was all copied...

However, Xie Wei believed that Professor Yu was the first to develop this type of structured high-energy explosives.

The reason is simple: the process of Americans synthesizing CL-20 explosives requires the use of palladium as a catalyst. During the reaction, this precious metal, which is more expensive than gold, is continuously consumed, resulting in the production cost of CL-20 produced by Americans as high as $3.5 per kilogram!

This was the price in the 80s.

After continuous improvement, China has established a large-scale industrial production line, which has reduced the cost of this high-energy-density explosive to more than 1000 yuan per kilogram and exported it to the United States...

"Oh, there's another person called Zhao Xinqi. I don't know where he is exactly. Please look him up. He graduated from the School of Chemical Engineering and Materials of Capital Institute of Technology in 65. If you find him, get him to work as an assistant researcher for Professor Yu."

Professor Yu Yongzhong has already been brought here, and it won’t be a big deal if we also bring in Zhao Xinqi, an expert who hasn’t even started his postgraduate studies, to speed up the process.

"Okay, you just like to assign tasks to me! Who else do you want? Tell me and I'll get them all for you."

"How about you invite Mr. Qian to be a visiting professor at the school?"

"Well, just pretend I didn't say anything."

Li Rui turned around and walked outside.

He even forgot that he had to go with Xie Wei to discuss with Fang Pengju about carrying out the test of the rocket launcher to the front line to fight monkeys.

Li Rui fled in panic, while Zhai Xinguo and Tang Daoxian, the master and disciple who rarely talked to each other, looked at each other.

"Professor Zhai, Old Tang, you have to find a way to produce a high-powered warhead as soon as possible. Foreign customers will be coming soon. By then, whether it is a disposable rocket launcher or a 40mm sniper grenade, it will be a powerful weapon for foreign customers whose army has poor combat effectiveness!"

Looking at the teacher and the student, Xie Wei solemnly revealed to them the news that a foreign customer would soon come to China to inspect and purchase weapons and equipment. "When?"

Zhai Xinguo suddenly became alert.

If the weapons they design and develop can be exported to earn foreign exchange, will the school not provide follow-up research funds?
"I don't know at the moment, but just hurry up."

Xie Wei was not sure when the Thai delegation would arrive, "Maybe after the New Year..."

"Then time is a bit tight."

The joy on Zhai Xinguo's face was soon replaced by worry.

"Don't worry, these weapons can provide individual soldiers with stronger firepower and are in great demand in the international market!"

Xie Wei comforted Zhai Xinguo.

Individual weapons can be used on any battlefield, and customers can buy less if they have less money.

Unlike some advanced large equipment, there are also requirements for customers.

He also talked to the two of them about some of his ideas. In fact, Xie Wei took the opportunity to speak out the related designs he knew. Not all of them can be used directly, but they can be made without much time and effort.

"Class monitor, there is a classmate in our class who likes chemistry research. How about letting him try out the aluminum-containing explosive you proposed with me?"

Xie Wei walked away for a long time before Tang Daoxian caught up with him from behind and made a proposal nervously.

Are there any students who like chemical research?

Didn’t Mo Lingyu do statistics in class before?
Moreover, our homeroom teacher Luo Yang also told the students that if anyone needed to adjust their study or research direction, they could go to him.

As a class teacher, Luo Yang, the school's principal, is qualified. He assigns the most technically skilled tutors in the school to every student in the class.

This put a lot of pressure on Liu Debao, the head teacher of the 79 experimental class.

"As long as Professor Zhai agrees, you don't need to ask for my opinion. Who is it?"

"Xue Xiaoqiang..."

"He?"

Xie Wei only had a vague impression of Xue Xiaoqiang. He was very introverted, had a low sense of presence, and rarely took the initiative to communicate with his classmates.

But he studied very hard and completed his work on the computer very seriously.

"He said he likes chemistry more, or more precisely, explosives. He never had the chance before. The students in the chemistry department mainly deal with daily chemicals and spices..."

Tang Daoxian had been observing Xie Wei's reaction.

Xie Wei was speechless.

How come the Department of Chemistry is only concerned with daily chemicals and fragrances?

There are quite a few projects over there.

However, Xie Wei did not explain that he didn't even know about some of the projects.

"Well, I'll go tell Professor Zhai, and you can ask him to go find his class teacher. I'll also say hello to Director Yu later."

Xie Wei had no objection at all to his classmates changing their research direction.

But he really didn't understand. He could just ask the class teacher, why did he have to ask for his opinion?

"Excuse me, squad leader."

Xie Wei just smiled, said it was okay, turned around and went back to tell Zhai Xinguo.

He didn't ask Tang Daoxian anything, but just told Zhai Xinguo that he just remembered that Xue Xiaoqiang had contacted him before, and it just so happened that the project happened to meet, so he let him participate in the project first, and Kang Yi would arrange someone to take care of him first.

Zhai Xinguo naturally would not object.

Xie Wei had been working on the progress of the programmable switching system in the design room for some time. He basically lived and ate on the fifth floor of the civil engineering building, so he simply went to the wind tunnel laboratory.

In the end, no one was found.

After asking the staff, no one told them where Xie Wei, Fang Pengju and others had gone.

I had to ask Li Rui and found out that Fang Pengju's entire project team had been in a factory 700 meters away from the school during this period.

"Weren't they always modifying the design? How come it was produced so quickly?"

Xie Wei asked Li Rui puzzledly.

It didn’t take long from Xie Rou to the rocket launcher project.

"When Xie Rou arrived at the project, the manufacturing of parts had already begun. Only a part of it was improved. You can ask Fang Pengju about the specific situation. I am not very clear. Didn't the school give him part of the project funding at that time?"

Li Rui felt painful when he thought about how Xie Wei asked the funds given by the department to be used for the rocket launcher project.

It’s hard to ask for money from the ministry now.

It is also difficult to defraud money from other machinery industry ministries.

The funds required for schools are increasing.

It costs money to build infrastructure, it costs money to build laboratories, and it costs even more money to conduct project research...

Xie Wei was too lazy to pay attention to him. The old guy always wanted the school-enterprise office to hand over more profits to the school. How could it be possible!
He ignored the old man and went straight to the workshop where the WZ-122 tank prototype was previously placed.

There was still no sign at the factory gate, which was different from what Xie Wei saw when he first came here: the factory gate, which was originally unguarded, now had guards arranged, and they were all unfamiliar faces that Xie Wei had never seen before.

Just as Xie Wei was about to walk into the factory, he was stopped by a burly guard in a military coat. He then pointed to a black sign on a white background and said, "Comrade, there is a sign next to it. Non-factory staff are prohibited from entering."

Xie Wei was stunned.

The old man didn't tell me this just now.

"Comrade, please tell Professor Fang Pengju that Xie Wei is here to see him."

Xie Wei didn't know there would be guards, so naturally he didn't have a pass.

"Looking for Professor Fang? Who are you?"

The guard asked Xie Wei.

"Xie Wei, Experimental Class 78."

"You are Xie Wei? Xie Rou's brother?"

Seeing Xie Wei nod, the guard said "Please wait a minute" and ran inside quickly.

Xie Wei was confused, what was Xie Rou doing here again?

"Brother~"

When Xie Wei was wondering why the guard referred to him as "Brother Xie Rou" instead of someone's student, Xie Rou's voice came into his ears.

Xie Rou was jumping and skipping behind Fang Pengju, and she was still far away when she rushed towards Xie Wei.

"Brother, come on, I'll take you to see the gun we made!"

When she arrived in front of Xie Wei, she pulled Xie Wei and walked towards the factory area.

Xie Wei looked at the guard, "Do you need to register?"

"No need. The principal got you a pass before. Didn't he give it to you?"

Hey!
Xie Wei cursed the old man Li Rui in his heart again. It was obvious that the old man had bad intentions. He didn't even tell him about this when he went to see him just now.

"I haven't seen the principal yet."

Xie Wei replied with a smile.

After saying hello to Fang Pengju and Wang Yuting who followed them out, they walked inside.

"You came just in time. I was planning to ask Feng Ke to find you and ask you to come. We will be leaving in two days."

"Let's go? To take the test?"

"Well, the National Shooting Range."

Xie Wei didn't know where the national shooting range was, and he didn't ask.

"how much time is required?"

"If all goes well, I'll be back in August."

"..."

"Brother, how about you go to the Gobi Desert with us?"

Xie Rou didn't care whether it was a secret or not, and said to Xie Wei.

What the hell?

Gobi Desert?
"High and low temperature tests. Since the project was initiated by the school itself, no telemetry missile tests were done... In order to speed up the research progress, we used the research results of the H-241 project..."

Fang Pengju did not reprimand Xie Rou, but explained the specific situation to Xie Wei.

“This seems to be somewhat out of touch with our school motto.”

The motto of Harbin Institute of Technology is "Strict Standards and Thorough Work", but now when it comes to the research work related to the school-enterprise partnership, it seems that despite the financial support, none of them are strictly following the previous procedures step by step.

"How did this violate the school motto? Our specifications are very strict, and we did it strictly according to the design requirements!"

Xie Rou was unhappy. "Although there is no telemetry missile test, the simulation results show that when the cage-type director was launched, it would cause the lateral density to decrease and the dispersion range to expand..."
