Chapter 123 It's called "C" (4k)

After intense preparations, with a command, the solid rocket engine on the test bench lit up with a flash of fire, smoke rising, and making a continuous "boom boom boom boom~~~~~~" sound.

Soon, the flame went out, and the whole process took less than 20 seconds.

The Institute of Carbon Research, the Institute of Carbon Research, and many other factories, institutes, and academies worked together for this short period of time. What is short? This is short.

This naturally includes the third steel rolling mill that provided the 591 engine casing material.

As for Gao Zhendong, needless to say, he really helped a lot.

The solid rocket engine fuel has burned out, but the experiment is not over yet. Next, it is time to measure various aspects of the new throat liner after the engine is working.

The experiment is not completed after one set of tests. A total of five sets of tests were conducted in the entire process to fully grasp the situation and avoid the randomness caused by conducting the experiment only once.

If this kind of experiment is only done once, the consequences of being too lucky are often far more serious than being bad luck.

After completing the entire process, the experimenters began to collect and analyze the data.

From the perspective of direct characterization, there are not many data items that need to be tested for the throat lining, and the analysis is quick; the others can be put aside for later testing and analysis.

Zeng Gong took a look at the data and nodded: "Well, Lao Duan and his team did a good job this time."

His tone seemed calm, but his slightly trembling hands betrayed his current mood.

Turning back, he reported to the model chief designer: "The data is very good. Under a pressure of X MPa, the ablation rate is about 60% lower than that of the original material, only 0.xxx mm/s. The data fluctuations of multiple tests also meet the requirements. Now, we can use it with confidence."

The chief designer asked, "Is it strong enough?"

Zeng, who had seen the test data from the Carbon Research Institute, had a good memory and reported it off the top of his head: "The axial shear strength reached X~XX MPa, and the thermal shock resistance was very good."

The chief designer shouted, "I originally thought that we were just practicing with an unexploded bomb and that we might still have to rely on the north in the end. I didn't expect that after all these setbacks, the prospects seem to be getting brighter and brighter."

Zeng Gong smiled and said, "Yes, we have solved the problem of infrared detection, and the engine has basically been solved. We have some basic knowledge of other technologies, and it seems that we can really make it."

In fact, what they didn't know was that even with the K-13 in the north as a prototype, the biggest problems with the later imitated Thunder-2 missile were still concentrated in several aspects.

The infrared detector has insufficient sensitivity, the detection distance of the seeker is short, the anti-interference ability to the sun and sky background is low, the fuse explodes prematurely, the average speed of the missile is low, and the low-altitude launch range is short.

The first few items are mainly problems with the infrared seeker, and the last two are mainly problems with the engine. Because the aerodynamic shape of the improved Thunder-2B missile that solves the above problems has not changed much, the main improvement is still in the engine.

Now the infrared seeker directly uses the second-generation cooled infrared seeker technology, and the changes brought about by the use of advanced materials in the engine casing and throat lining enable the engine to operate under more stringent conditions.

Although the propellant is still not as good as the PL-20B more than 2 years later, there is no doubt that, overall, the engine performance is much better than that of the PL-2 and even the K-13.

The remaining problem of premature detonation of the fuse will not have much impact on the finalization of the missile. Perhaps without so many other problems to worry about, they can solve this problem as well.

The older generation of scientific and technological workers lacked the qualifications rather than the brains.

The chief engineer talked with Engineer Zeng for a while, and suddenly remembered something. He said to Engineer Lu who came to observe the test: "Old Lu, have we sent the appointment letter for Comrade Gao Zhendong as a consultant? You know what, these recent things are really thanks to him."

Engineer Lu shook his head. "Not yet. He hasn't been working on materials and processes in the company for some time. He was invited by the Institute of Computing to work on computers. I heard he's back. Isn't the training course on scientific research project management that he's in charge of going to start? So, Lian Wei, send it to him later."

After hearing Engineer Lu talk about Gao Zhendong's various and unrelated jobs, and thinking about his own institute and the Carbon Research Institute, the chief engineer couldn't help but shook his head, sighed, and expressed admiration.

At this time, Gao Zhendong was staring at a large package that was sent by someone else. His comrades over there had never said anything about bringing him anything.

This is Duan Gong from the Carbon Research Institute. He brought it to Gao Zhendong while delivering something to the Guidance Research Institute.

However, he had a keen nose and smelled the aroma of pickled meat. In addition, there was a simple word "Duan" written on the package, which reminded him of the generous and meticulous Duan Gong from the Northeast Carbon Research Institute.

I guess it was sent by him. This style looks like his.

Without much hesitation, Gao Zhendong opened the package.

There was a letter inside. When I opened it, I found that it was written by Duan Gong as I had guessed.

In the letter, Duan Gong, on behalf of the unit, expressed gratitude to Gao Zhendong, and also offered some mountain products as a token of his gratitude.

In addition, the letter also mentioned one thing. In view of Gao Zhendong's strong support and important role in the research of graphite throat lining materials, we may bother Comrade Gao Zhendong in the future.

Their unit specially hired Comrade Gao Zhendong as a technical consultant. It's just a title, no other benefits. I hope Comrade Gao Zhendong doesn't mind.

Gao Zhendong was quite happy. Whether he was rich or poor was not important to him, but having a title could sometimes play an unexpected role.

I opened the package excitedly, and found that it contained pickled or dried mountain products, including those that fly in the sky, run on the ground, sleep in caves, grow on trees, and swim in the water. It was quite complete.

Looking at this pile of things, Gao Zhendong was a little excited. It was at this moment that he realized that this pile of things would be enough for him to use a sewing machine for a lifetime in his previous life.

These things really cannot be retrieved from his system, otherwise those stores would have closed down long ago.

This time, Sha Zhu is going to be in trouble. When Gao Zhendong thought about it, he almost drooled.

But they couldn't finish it anyway, so they gave some to the master, some to Wang Dezhui, and some to Shazhu. Then they would eat the rest themselves when Lou Xiaoe came over. It was perfect.

The consultant's appointment letter was nicely wrapped in oil paper and placed inside the package. Gao Zhendong took it out and put it in front of his nose. Hmm, it smelled like pickled meat!

Duan Gong, who was far away in the northeast, seemed to have sensed something and felt that he had forgotten something. After thinking for a long time, he suddenly slapped his head and said, "Oh no! Lao Zeng and his friends have roe deer legs! We have to get them quickly!"

On this side, before leaving get off work, Gao Zhendong ran to Lao Chen's office and left his things to him. It was already quite difficult at this time, as these things might not be bought even if one had money.

Then he quietly put the rest into the storage, put a roe deer leg, a salmon, a flying dragon bird, and some dry goods, wrapped them up layer by layer with two cans of milk powder, so that you couldn't see what was inside from the outside, put them on the bicycle, and rode straight to Wang Dezhuo's house.

Wang Dezhui was at home. Wan Yueqin was about to give birth and there were no classes. Wang Dezhui went home quickly after work. The institute also knew about his family situation and tried to reduce the workload of the deputy director as much as possible during this period.

Seeing Gao Zhendong, Xiaomei rushed over. Gao Zhendong held the package in his left hand and Xiaomei in his right hand, and walked into Wang Dezhui's room.

Wang Dezhu was busy cooking. When he saw Gao Zhendong come in, he propped his chin up on the chair as a greeting.

Gao Zhendong put Xiaomei down, closed the door of Wang Dezhu's house, and called Wang Dezhu: "Big Boss Wang, come and see what I brought."

Wang Dezhui put down his work and walked over. When he came over, he saw Gao Zhendong opening the package.

Before it was fully opened, Wang Dezhuo could already smell something.

"Old platoon leader, meat?"

Gao Zhendong nodded: "It was sent by a friend from the Northeast. I'll share some with you." Wang Dezhu smiled happily. At this time, it was difficult to buy meat even if you had money. His wife was about to give birth, and he was just thinking about where to get some meat when Gao Zhendong delivered it.

After opening the package and looking at the pile of things inside, Wang Dezhu patted Gao Zhendong twice: "Old platoon leader, I won't say anything else. Thank you."

After saying that, he was about to cut some roe deer meat and prepare to eat it with Gao Zhendong.

Gao Zhendong waved his hand to stop him: "No, no, save it for my sister-in-law. I'll eat whatever you make now. Anyway, I have to eat this meal."

Understanding what he meant, Wang Dezhui didn't act pretentiously. This pile of things could completely solve Wan Yueqin's nutritional problems before and after delivery.

Meat + milk powder, even if there is no milk, there is no need to worry about the second child going hungry.

Xiaomei, on the other hand, cut a small piece of roe deer meat for her, put it on an iron skewer and roasted it. She was very happy with half her face covered with cigarette ash.

Wan Yueqin looked at the two of them with a smile, without saying much, but the expression in her eyes was very peaceful.

After dinner, when they parted, Gao Zhendong whispered to Wang Dezhu: "I can still get these things. If you need them, just let me know. I have many ways to get them in other places."

After saying that, he gently pinched Xiaomei's face and rode away on his bike.

Wang Dezhu shouted from behind: "Old platoon leader, if you want children, get married and have them yourself."

“Almost there~~~Almost there~~~”

Hearing Gao Zhendong's words coming from afar, Wang Dezhu was very happy. Now, his little cotton jacket would not fly away.

The next day was the first day of training on the project management system. Gao Zhendong looked at Director Li of the Operations Institute and Chief Engineer Chi with a look of surprise.

It's still morning, didn't I ask you to come in the afternoon? If you come now, I won't be able to greet you.

Perhaps understanding Gao Zhendong's doubts, Director Li took out a book called "Project Management System" and said with a smile: "Don't be surprised, I'm here to participate in the training too, it's just right."

Gao Zhendong suddenly realized and said with a smile: "Ah, right, right, look at my memory. I will ignore you for the time being."

Turning around, Lin Lianwei was standing in front of him, holding a file bag in his hand: "Lao Gao, come here, this is the appointment letter for you to be a consultant in our hospital. You are awesome. You are not in our unit, but we have a legend about you in our unit."

Gao Zhendong was a little amused and said, "You guys have discussed this beforehand, right?"

He really didn't know that, to some extent, this was a discussion between Engineer Zeng from the Guidance Research Institute and Engineer Duan from the Carbon Research Institute, and then reported to the institute for execution.

It wasn’t a bad thing anyway, so Gao Zhendong took it.

As the time reached 9 o'clock, the training officially began.

At noon, Gao Zhendong invited the people from the Institute of Computing to have a meal. After the meal, since they were there anyway, they decided to solve the C language issue at noon.

This will give them no excuse to avoid the afternoon quiz, Gao Zhendong thought sinisterly.

After changing shoes with a few people, I entered the computer room.

The people in the Operation Institute saw that a program option with a very simple name, "C", appeared in Gao Zhendong's loop duty environment.

This option is not included in the program that Gao Zhendong provided to the Institute of Computing.

C? What is this thing? A group of people wondered in a strange way.

However, when Gao Zhendong chose to run C and started writing code in it, they began to understand something.

Director Li and Chief Engineer Chi looked at each other and asked softly, "ALGOL60? Fortran?"

As the top experts in the field of computer in China, they understand these two things.

They were planning to organize people to implement the Fortran language in DJS-59. This language, which was born in IBM and is suitable for numerical calculations, is very important for people today.

But then, without Gao Zhendong's answer, they knew they had guessed wrong.

What Gao Zhendong inputs is very different from these two languages.

But the two could see that this should be a computer language.

A new computer language? ! !

The two suddenly realized what they were looking at.

Calm down, calm down, so what about computer language? Maybe it’s just a very simple thing with limited functions.

It seems that compared with the previous two, this language has much greater freedom.

Because Gao Zhendong didn't care how many spaces he entered.

This sounds like a joke. Is the freedom of language determined by a few spaces?
But in fact, this is a kind of evidence.

Computer languages ​​that were born in the early days have very strict requirements on formats. The reason is actually the problem of the entire computer system at that time, which resulted in no way or not much ability to handle flexible formats.

What to do? Let programmers suffer.

Write it strictly according to the format!

But Gao Zhendong's work doesn't seem to be like that. He handles the format very casually.

While the two were still thinking, Gao Zhendong had already quickly typed in three lines of code.

It looks a bit like another realization of Gao Zhendong’s classic “Ni Hao, Shi Jie!”

Indeed, as Gao Zhendong performed several operations, this classic sentence appeared on the screen as expected.

Three lines will solve the problem?

The two realized what they were looking at. It was a language similar to Fortran, which allowed people to completely ignore the underlying things of the computer, leaving aside registers, interrupts, stacks, and memory addresses.
Feel free to achieve everything you want!
Chief Engineer Chi asked in disbelief, "Director Gao, you made a computer language? Like Fortran?"

Gao Zhendong nodded: "Yes and no, it's called 'C', the first letter of our international English name 'C'."
