In 1978, I was admitted to Harbin Institute of Technology

Chapter 111: Tuluzui again: The air-to-air missile caused Xie Wei to get into trouble again

"It remains to be determined whether these are the reasons. Before I come back, the factory will organize a new round of production to determine why the pass rate has increased so much."

Yu Guofeng did not look happy about the significant improvement in the chip production yield rate at Factory 14. Instead, he showed worry.

"what happened?"

"I was the one who ordered the production to continue. If the pass rate is still so high, I'm afraid the school's projects will not be able to use them up."

Can’t use it all?
Xie Wei's eyes widened when he heard that Yu Guofeng was worried that there were too many chips to use up.

This is just a small amount, are you worried that you won’t be able to use it all?

Doesn’t Yu Guofeng, who works in computer science, know how big the gap in high-performance chips is in the country?

"Director Yu, you are the head of the Computer Department!"

Xie Wei was speechless. "I can understand that others are worried about this problem, but you are worried about this..."

"how?"

Yu Guofeng looked at Xie Wei in confusion.

"The calculator project is waiting for chips; the PLC and CNC projects of the Department of Mechanical and Electrical Engineering are also waiting. How many chips are needed for these projects? Not to mention how great the demand will be once the research is successful and the products are put on the market."

"I know all this."

There was no relief on Yu Guofeng's face.

This made Xie Wei confused, and he looked at Yu Guofeng with a frown.

"Everything is based on the premise of successful research and development. On the way back, I kept thinking: If the qualification rate is stable at more than 40%, and the products developed have not been launched on the market, what will happen to the production of Factory 14? When He Kun was running for factory director, he proposed that if 80 yuan could be given to replace old equipment, the product qualification rate could be further improved..."

"There are many units engaged in computer research and development in China, and they also need chips."

Hearing Yu Guofeng say this, Xie Wei felt a little panicked for no reason.

The performance of the HZ80 chip is relatively good, but it is in a rather awkward position: its level of advancement is not as high as the most advanced foreign ones; yet it is far ahead of domestic ones.

More importantly, a completely new architecture was used during the design. Xie Wei planned to redevelop the instruction set based on Chinese code, which is not compatible with foreign instruction sets.

As the head of the Computer Science Department, Yu Guofeng understands the project itself and the basic level.

By raising this question, it is obvious that one is aware of the problem.

"Yes, quite a few. But not every school is prepared to start computer research from the basics like we are."

Yu Guofeng spoke.

Xie Wei smiled awkwardly. At this moment he didn't know how to respond.

How can you explain it?

We can't just say that we can't let others strangle us. Even if schools and research institutes can't use so many chips, we can find a way to make domestic military equipment use our own chips!
"Factory 14 asked for 80 yuan to replace equipment. What do you think?"

Seeing Xie Wei's silence, Yu Guofeng did not pursue the topic any further.

"The funds for eliminating old equipment must be given! The principal has so much money in his hands. If he doesn't invest in upgrading money-making tools, is he going to keep it in the bank and earn interest?"

Xie Wei said without hesitation.

The ministry only gave 1200 million.

“It is better to upgrade the equipment and wait for the product, rather than wait for the product to come out and then wait for the equipment to be upgraded. The development speed of computer hardware will be faster and faster!”

In the 80s, with the increasing use of computers, especially the continuous expansion of personal computers in the market, computer functions have been continuously developed and extended, which has put forward higher computing speed requirements for the computer's core data processor.

The concept of personal computers emerged in the 70s. In 1973, Xerox Palo Alto Research Center developed the microcomputer Alto. In 1977, Apple launched the first personal computer Apple II with integrated keyboard, display, and storage device. In 1981, IBM launched the first IBM PC.

Now, we have just entered 79 years!
In terms of electronic basics, production technology, etc., China is indeed not as good as foreign countries.

But if we try hard, even if we can't catch up with foreign countries, we won't have to use imported chips that could choke us at any time for decades to come.

There is no need to wait until more than 20 years later to discover problems before starting to develop Loongson.

Xie Wei knew very well that if he could not catch up with the advanced foreign level during the second computer wave that began in 84 and before computer commercial standards were established, domestic computer development would eventually return to the old path.

Functions such as local area networks that further promote the development of computers have higher technical requirements.

Now we are already behind.

You don't have to catch up with foreign countries, but at least you can't fall too far behind, and you have to make sure you have your own.

“The investment will not be small.”

Seeing Xie Wei's firm attitude, Yu Guofeng wanted to persuade him, but finally gave up.

He knew very well that the smarter the young people were, the less likely they were to listen to advice.

Too much persuasion will have the opposite effect.

Xie Wei knew what Yu Guofeng meant, but he couldn't explain it. "Director Yu, you didn't report to the principal first when you came back. I'm afraid the old man will cause trouble when the time comes!"

"He probably doesn't want to see me."

Yu Guofeng said with a wry smile.

really.

When Yu Guofeng reported the situation of Factory 14, Li Rui said impatiently: "Factory 14 is the business of the school-enterprise partnership. Why are you telling me about it?"

When the old man heard this, he glared at Yu Guofeng with his beard puffed.

He felt that Yu Guofeng was asking for money.

We finally managed to coax 1200 million yuan in funding from the ministry. Although expanding the school and building dormitories will cost several million yuan, every school project is a money-consuming behemoth.

That's all the money I have.

"I don't want money."

"Don't give me that! Now that we have the chip, the computer department is conducting research based on the chip, and you don't want to ask the school for funding?"

At this moment, Principal Li was the most sober person in the world.

"..."

Yu Guofeng was so choked by these words that he didn't know how to continue.

Shouldn't the school provide funding for research into computer technology?

"President, are you sure that all chip-based research has to be borne by the school-enterprise office?"

Xie Wei on the side didn't tolerate it and asked directly with a smile.

Li Rui was about to reply with affirmation without hesitation, but when he saw the expression on Xie Wei's face, he instantly felt that the other party must have set a trap for him again.

After a moment of silence, he looked at Xie Wei and said, "Tell me the reason."

"This chip can be used to develop scientific research computers with good computing performance, which can help schools speed up the progress of projects that require a lot of computing. It can also make missile tracking more powerful. It can also make radar detection more accurate and efficient. It can..."

"Stop!

Li Rui said several "stops" in a row, looking at Xie Wei with a look of despair, "You said at the beginning that you didn't want to take the money!"

Everything Xie Wei proposed hit the principal's sore spot.

Who is Principal Li?
The president is determined to turn all the school's projects into military projects and strive to make the school the number one military engineering school!
It doesn’t matter whether it is the best university in the country.

It must be the number one military engineering college, a military engineering college that is even better than Harbin Institute of Technology!

"I have no intention of taking this money!"

Xie Wei shrugged and spread his hands.

Looks indifferent.

"I'm just stating a fact. For example, even if an air-to-air missile has a better infrared seeker, if the central data processor that controls the missile's flight attitude doesn't have a good computing speed, it won't make the missile more agile in the air, right? A tactical maneuver by a fighter jet can cause the missile to lose its target..."

"Bang~"

The hand slammed heavily on the table.

The enamel teacup "Dedicated to the Loveliest Person" jumped up.

This time, the desk did not fall apart due to external force.

Apparently the logistics department didn't listen to the principal this time and fixed it.

Li Rui stood up suddenly, supported himself on the edge of the table with both hands, and stared with bloodshot eyes: "How much do you want? Just tell me!"

"..."

Xie Wei was dumbfounded.

The principal's reaction was so intense that it was beyond Xie Wei's imagination.

Xie Wei couldn't help but look at Yu Guofeng in confusion. The latter shook his head bitterly and didn't give Xie Wei any explanation.

"Are you sure this thing can improve the missile's mobility in the air? If you are sure, I can give it to you within 400 million! If not..."

Li Rui looked at Xie Wei with red eyes.

That murderous look made Xie Wei take two steps back.

The old man has been to the battlefield, and he probably stared at the enemy with the same look at that time, right?

This is Xie Wei's truest feeling at the moment. "Ahem~Ahem~Principal, Xie Wei doesn't understand the situation."

Yu Guofeng, who was standing by, saw Xie Wei's expression and knew that the principal's reaction was scary, so he coughed twice to bring Li Rui back to his senses.

Li Rui also realized his mistake and came to his senses. Looking at Xie Wei with a complicated expression, he said in a low voice: "What I just said is still valid. As long as I am still the principal, the school's activity funds can be given priority to the project you proposed."

"why?"

Suppressing the confusion and shock in his heart, Xie Wei asked.

Li Rui's promise is indeed very important.

Xie Wei simply couldn't understand the old man's abnormal behavior.

"Yu Guofeng, tell him."

The principal pretended to be calm, picked up the empty enamel teacup beside him, and pretended to drink tea to cover up his gaffe.

"Ah~"

Yu Guofeng glanced at Li Rui, then at Xie Wei, and sighed.

After a long while, he finally spoke: "I really don't know if you said that casually, or if you already knew it and are using it to pressure the principal to ask for funding."

Hearing this, Xie Wei was even more confused.

What do you know?
I do have a grasp of it, but the problem is, aren't what I said necessary?
"Starting from PL-1, all air-to-air missiles cannot solve the problem of missing the target during target practice tests. Especially PL-4... The only air-to-air missile that our troops can use at present is the PL-13 air-to-air missile that imitates the K-2. The technology of that air-to-air missile is already outdated... And the school also has this project..."

"what……"

This time, Xie Wei was so shocked that he didn't know what to say.

Tell the truth.

He had no idea that the school had such a program.

He did know about the PL-2. It was said that in 58, the troops picked up a complete AIM-9 Sidewinder air-to-air missile. Due to insufficient technical reserves, they provided the missile sample and related information to Soviet experts. In 1960, the Soviet Union successfully developed the K-9 air-to-air missile based on the AIM-13, and in 62, the technology of the K-13 air-to-air missile was transferred to China, thus the PL-2 air-to-air missile was born.

The PL-5, which will be finalized in a few years, is also an upgrade based on the PL-2.

Xie Wei didn't know much about air-to-air missiles.

Anyway, we know that for a long time, not only the fighter planes of the Air Force were short in length, but also in swords.

"The school agreed to give priority to the integrated circuit project before, and it was not just for the electromechanical department. Otherwise, do you think that with less than 200,000 yuan in funding, all the electronics and computer personnel in the school were mobilized just for that project?"

Yu Guofeng's words confirmed some of Xie Wei's previous speculations.

Computer hardware development belongs to the field of electronic engineering; while computers are mainly related to software development.

The fact that the school has not recruited students in the computer major for many years, but still has a computer department and Yu Guofeng as the department director is something that makes people suspicious.

"The reason is the same for Factory 14, right?"

Xie Wei understood.

It seems that the school leaders are more shrewd than each other. If they hadn't made up those reasons just now, and hadn't used the example of air-to-air missiles, and the current development of air-to-air missiles happened to be at a bottleneck, they would probably always think that the school values ​​them so much.

Think about it too.

Even if you have been working for five years and have demonstrated some scientific research ability and learning, it shouldn't be something that the school pays so much attention to, right?
Everything is clear.

"Almost. The school laboratory cannot produce advanced integrated circuits. It costs more money to purchase equipment and set up laboratory conditions for production... It won't be a loss to have a factory with production capacity and products, right?"

Li Rui did not deny it.

As a result, Xie Wei looked at him with contempt, "Why are you pushing everything onto the school-enterprise office? Principal, you should have some conscience!"

Li Rui raised his eyebrows and looked at Xie Wei with a pout.

That expression clearly said: What is conscience? How much is it per pound? Can you eat it?
Seeing his expression, Xie Wei knew that his words were in vain.

"Tell me about using integrated circuits to improve missile accuracy!"

Li Rui instantly became serious and didn't talk to Xie Wei about anything else.

Xie Wei was about to find an excuse not to talk about this, but was glared at by Li Rui's sharp eyes again.

The hairs on my back instantly stood up: I had never seen such a look in the old guy's eyes before!

Even more ferocious than before.

"In fact, improving the hit rate of air-to-air missiles is similar to detecting radar tracking/locking technology... Fighter planes are constantly changing their positions in the air. After the active guided missile is launched, without the guidance of the fighter radar, it relies on the infrared seeker to detect the target's thermal radiation, or the missile's own radar to detect the target, and then transmit the signal to the guidance system's data processor. The data processor quickly processes the signal, determines the target's position, issues instructions to the missile flight control system, and adjusts the missile's flight attitude..."

Not very knowledgeable about technology.

Xie Wei still knew the basic theories.

"Don't talk about it here. Wait, I'll find some professionals and you can talk to them."

After Li Rui finished speaking, without paying any attention to Xie Wei's suddenly widened eyes, he turned to the door and told Yuan Zhenyue to go find someone.

"Is our school really researching air-to-air missiles?"

Looking at Li Rui's actions, Xie Wei asked Yu Guofeng.

Although Li Rui had told him before that the school had this project, Xie Wei didn't believe it at all.

It was said that the missile-related majors of Harbin Institute of Technology moved south with Harbin Institute of Technology in 70 and were merged into Changsha Institute of Technology.

"The school has more than a thousand faculty members. Do you think that less than two thousand students need so many teachers and professors? What do they do if they don't teach?"

Yu Guofeng did not directly answer Xie Wei's question.

But his answer shocked Xie Wei even more.

How many people are involved in teaching in the entire school?

This means that the school has many other important projects that you may not have thought of!
All of a sudden, I understood why, decades later, even Peking University and Tsinghua University couldn't poach professors from our school.

The reason on the Internet at that time was that the annual income of professors at Harbin Institute of Technology was over 200+, and the unit was W.

This is unbelievable.

After all, it is generally believed that the income from scientific research in China is far less than that abroad.

There is also news online that the "Youth Project" for the introduction of science and engineering talents at Harbin Institute of Technology offers an annual salary of no less than 70 yuan/year + a special subsidy of 10 yuan/year (paid for 6 years), and provides a fully decorated new house (over 160 square meters) or a resettlement allowance of 200 million yuan...

According to Xie Wei's understanding, the school's recruitment information shows that the annual salary of an associate professor is 28 yuan and that of a professor is 35 yuan. Relatively speaking, this income is still very low.

Therefore, an annual income of more than 200 million seems unbelievable.

Only then did Xie Wei understand why Peking University and Tsinghua University could not poach professors from Harbin Institute of Technology: they could get higher salaries than other schools and make contributions to national defense, so why should they leave?

The winter is too cold and the environment is bad?
There are two other campuses too!
"Wasn't the school's missile engineering department merged with Harbin Institute of Technology?"

“That’s only part of it.”

Yu Guofeng didn't want to talk to Xie Wei about how many majors and talents his school had lost to Harbin Institute of Technology.

There were 800 brave men in the school back then. As soon as Harbin Institute of Technology was established, half of them were snatched away. Who can they cry to?

"So, the school still undertakes a lot of military research projects? Can I know what they are?"

Xie Wei knew that he would not get an answer, but he still asked without giving up.

Sure enough, Yu Guofeng didn't say anything.

"Haven't you memorized the Confidentiality Code? I think your class needs to strengthen political and ideological education. Comrade Guofeng, please remember this and communicate with Comrade Luo Hao. When scheduling classes for the experimental class after the New Year, include political and ideological education..."

"..."

Li Rui's words gave Xie Wei the urge to greet his female relatives.

The experimental class has many courses, and students also need to participate in various projects.

Because of these courses, we did not have a special political ideology class in the first semester like other classes. Principal Li and the class teacher Luo Hao both agreed that the students were all educated youth who had been to the mountains and the countryside and had a high level of political awareness, so it would be sufficient to hold ideological meetings during the weekly class meetings.

If this matter gets out, the whole class will secretly curse Xie Wei.

Given the old guy's character, it will definitely get out.

"Leader, air-to-air missiles are also a national military secret. I'd better not learn about them..."

After saying that, he wanted to run away.

As a result, Li Rui grabbed one of his arms and dragged him back.

"Boy, I won't bother with you if you are being mad or playing tricks on me, but if you dare to talk nonsense to me about this matter, hmph..."

Li Rui didn't mention the consequences.

But the look on his face...

Threat!

An absolute threat.

Xie Wei had no intention of resisting at this moment.

I couldn't help but wonder in my heart, "Could this old man have been in the Air Force?"

As soon as this thought flashed through his mind, he quickly discarded it: when he was fighting against 17 gangs alone, the fighter planes were still fighting in close range with machine guns and cannons.
