Chapter 123 It’s called “C” (4k)
After intense preparations, following an order, a flash of fire lit up the solid rocket motor on the test bed, smoke rose, and a continuous “boom, boom, boom, boom, boom, boom, boom, boom, boom, boom, boom, boom, boom, boom, boom, boom, boom, boom, boom, boom, boom, boom, boom, boom, boom, boom, boom, boom, boom, boom, boom, boom, boom, boom, boom, boom, boom, boom, boom, boom, boom, boom, boom, boom, boom, boom, boom, boom, boom, boom, boom, boom, boom, boom, boom, boom, boom, boom, boom, boom, boom, boom, boom, boom, boom, boom, boom, boom, boom, boom, boom, boom, boom, boom, boom, boom, boom, boom, boom, boom, boom, boom, boom, boom, boom, boom, boom, boom, boom, boom, boom, boom, boom, boom, boom, boom, boom, boom, boom, boom, boom, boom, boom. ~~~~~~" sound.
Soon, the flame went out and the whole process took less than 20 seconds.
Many people from Guangdong Research Institute, Carbon Research Institute, and other factories, institutes, and institutes work together for this short period of time. What is short? This is called short.
This naturally includes the third rolling mill that provides 591 engine casing materials.
As for Gao Zhendong, needless to say, it really helped a lot.
The solid rocket motor fuel has burned out, but the experiment is not over. Next, it is time to measure all aspects of the new throat liner after the engine is working.
One group of tests is not complete. A total of 5 groups were conducted during the entire test process to fully grasp the situation and avoid the contingency caused by only doing it once.
If this kind of experiment is only done once, the consequences of good luck are often far more serious than bad luck.
After the entire process was completed, 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 inspected for the throat lining, and the analysis is very fast. Others can be inspected and analyzed later.
Zeng Gong took a look at the data and nodded: "Well, Lao Duan and the others did a good job this time."
The tone seemed calm, but the slightly trembling hands still made him My mood was betrayed.
Turning his head, he reported to the model chief engineer: "The data is very good. Under the pressure of X MPa, the ablation rate is about 60% lower than the original material, only 0.xxx mm/second. The data fluctuations of multiple tests also meet the requirements. Now, we can use it with confidence."
The chief engineer asked: "Is the strength enough?"
Zeng Gong, who had seen the test data from the Carbon Research Institute, had a good memory and reported it casually: "The axial shear strength has reached X~XX MPa, and the thermal shock resistance is very good."
The chief engineer yelled: "I originally thought that if we took an unexploded bomb to imitate it, that is, to practice our skills, we might end up going to the north. Unexpectedly, after this stumble, the prospect seems to be getting clearer and brighter."< br>
Zeng Gong smiled and said: "Yes, infrared detection has been solved, and the engine has basically been solved. We have some foundation in other technologies, and it seems that we can really figure it out."
In fact, what they don’t know is that even with the K-13 from the north as a prototype, the biggest problems with the later imitated Thunder-2 missiles are still concentrated in several aspects.
The sensitivity of the infrared detector is insufficient, the detection range of the seeker is short, the anti-interference ability against the sun and sky background is low, the fuze explodes early, the average speed of the missile is low, and the low-altitude launch range is short.
Among them, the first ones are mainly infrared seeker problems, and the last two are mainly engine problems, because the aerodynamic shape of the Thunderbolt-2B improved missile that solves the above problems has not changed much, and the main improvement is still in the engine. .
Now the infrared seeker directly uses the second generation refrigerated infrared seeker technology, coupled with the changes brought about by the use of advanced materials in the engine casing and throat lining, the engine can work in a more under harsh conditions.
Although the propellant is still not as good as the Thunderbolt-2B more than 20 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.
There is only one problem left, the premature explosion of the fuze, which will not have much impact on the finalization of the missile. Maybe they don't have too many other problems to worry about, so it is unknown whether they can solve this problem.
The older generation of scientific and technological workers are more likely to have no conditions than no brains.
The chief engineer communicated with Gong Zeng for a while, and suddenly remembered something, and said to Gong Lu who came to observe the test: "Old Lu, have we sent the appointment letter for Comrade Gao Zhendong as a consultant? Don't tell me, these days Thank you very much for this."
Gong Lu shook his head: "Not yet. He was not working on materials and technology in the unit some time ago. He was invited by the computing department to work on computers. , isn’t the scientific research project management training he is hosting about to start? Who is that, Lian Wei, please send it to him later.” Thinking about the work of his own institute and the Carbon Research Institute, the chief engineer couldn't help but shake his head and clicked his tongue, expressing admiration.
At this time, Gao Zhendong was staring blankly at a large package delivered by a trustee. His comrades there had never said anything about bringing anything for him.
This is Duan Gong from the Carbon Research Institute, who brought it to Gao Zhendong while delivering something to the Institute.
However, his nose was very good, and he smelled the smell of cured meat. In addition, the word "Duan" was simply written on the package, which reminded him of the bold and delicate Duan from the Northeast Carbon Research Institute. work.
I guess it was sent by him. This style seems to be his.
Without much hesitation, Gao Zhendong opened the package.
There was a letter inside. When I opened it, I found out that I was right. It was written by Duan Gong.
In the letter, Duan Gong, on behalf of the unit, expressed his gratitude to Gao Zhendong, and also said that he was not grateful for a little bit of local product.
In addition, the letter also said one thing. In view of Gao Zhendong's strong support and important role in the research of graphite throat lining materials, and the possibility of disturbing Comrade Gao Zhendong in the future.
Their unit specially hired Comrade Gao Zhendong as a technical consultant. It’s just a title and no other benefits. I hope Comrade Gao Zhendong doesn’t mind.
Gao Zhendong is quite happy. It is no longer important to him whether he has money or not, but having a title may actually play an unexpected role sometimes.
I opened the package excitedly and found that it was indeed pickled or dried mountain products. There were some that flew in the sky, some that ran on the ground, some that slept in caves, some that grew on trees, and some that swam in the water. They were quite complete. Huh.
Looking at this pile of things, Gao Zhendong was still a little excited. At this time, this pile of things in his previous life was enough to use a sewing machine for a lifetime.
He really couldn't retrieve these things from his system, otherwise those stores would have been closed long ago.
This time I am going to trouble Silly Zhu. Thinking of this, Gao Zhendong almost drooled.
But the left and right couldn’t finish it, so they gave some to the master, some to Wang Dezhu, and Sha Zhu had some to eat first, and when Lou Xiao’e came over, the two of them made the rest by themselves. It was perfect.
The consultant's appointment letter was well wrapped in oil paper and put together in the package. Gao Zhendong took it out and put it in front of his nose. Well, it smells like bacon!
Duan Gong, who was far away in the northeast, seemed to sense something. He always felt that he had forgotten something. After thinking for a long time, he suddenly slapped his head: "It's broken, Lao Zeng's roe deer legs! We need to fix them quickly. Go!”
And here, before getting off work, Gao Zhendong ran to Lao Chen's office and left things for him. It was already difficult at this time, and even if he had money, he might not be able to buy these things.
Then the rest was quietly put into the storage room. A roe deer leg, a salmon, a flying dragon bird, and some dry goods were wrapped in layers with two cans of milk powder. They could not be seen from the outside. He found out what it was, put it on his bicycle, and rode straight to Wang Dezhu's house.
Wang Dezhu was at home. Wan Yueqin was about to give birth and was not in class. Wang Dezhu hurried home as soon as he got off work. The institute also knew about his family situation and tried to lighten the work of his deputy director as much as possible during this period. .
Seeing Gao Zhendong, Xiaomei rushed up with a bang. Gao Zhendong wrapped the bag in his left hand and Xiaomei in his right hand, and walked into Wang Dezhu's house.
Wang Dezhu was busy cooking. When he saw Gao Zhendong come in, he raised his chin on the chair to say hello.
Gao Zhendong put Xiaomei down, closed the door of Wang Dezhu's house, and called to Wang Dezhu: "Elder Wang, come and see what I have brought."
Wang Dezhu put down his work and walked over. When he walked over, he saw Gao Zhendong is opening the package.
Wang Dezhu could smell something before it was fully opened.
"Old platoon leader, meat?"
Gao Zhendong nodded: "My friends in the Northeast sent it to you, share some with you." Wang Dezhu smiled happily. At this time, there were already It was hard to buy meat with money. My wife was about to give birth and I was thinking about where to go to get some food. Gao Zhendong delivered it right away.
Opening the package and looking at the pile of things inside, Wang Dezhu patted Gao Zhendong twice: "Old platoon leader, don't say anything anymore, thank you."
After that, I need to cut off some roe deer meat and prepare it to eat with Gao Zhendong.
Gao Zhendong waved his hand to stop him: "No, no, keep it for my sister-in-law. I will eat whatever you make now. I must eat this meal anyway."
Understood. What he meant was that Wang Dezhu was not hypocritical. This bunch of things could completely solve Wan Yueqin's nutritional problems before and after giving birth.
Meat + milk powder, even if there is no milk, you don't have to worry about being hungry.
Xiaomei, on the other hand, cut a small strip of roe deer meat for her and roasted it on an iron skewer. Half of her face was wiped with soot, and she was very happy.
Wan Yueqin looked at the two people with a smile. She didn't say much, but the look in her eyes was very peaceful.
After dinner, when they were leaving, Gao Zhendong quietly said to Wang Dezhu: "I can still get these things. If you need it, please tell me at any time. I have many ways out of town."< br>
After saying that, he pinched Xiaomei’s face gently and ran away on his bicycle.
Wang Dezhu shouted from behind: "Old platoon leader, if you like children, get married and have them yourself."
"It's almost~~~It's almost~~~"
Hearing Gao Zhendong's words spread far and wide Come, Wang Dezhu looks happy. Now, his little cotton-padded jacket will no longer fly.
The next day was the first day of training on the project management system. Gao Zhendong looked at Director Li and Chief Engineer Chi of the Computing Institute with a look of astonishment on his face.
It’s still morning, didn’t I ask you to come in the afternoon? Now that you are here, I can’t greet you.
Perhaps understanding Gao Zhendong's doubts, Director Li took out a copy of "Project Management System" and said with a smile: "No need to be surprised, I am also here to participate in the training, just in time."
Gao Zhendong suddenly understood and smiled He said: "Ah, yes, yes, depending on my memory, I will ignore you for the time being."
Turning his head, Lin Lianwei stood in front of him, holding a document bag in his hand: "Old Gao, Come on, come on, this is the letter of appointment for our hospital to hire you as a consultant. You are awesome. You are not in our unit, but our unit has a legend about you."
Gao Zhendong was a little dumbfounded. You guys had agreed. Bar.
He really didn’t know that to a certain extent, this was what Gong Zeng from the Guidance Research Institute and Gong Duan from the Carbon Research Institute discussed and then reported to the institute for implementation.
This is not a bad thing, Gao Zhendong took it.
As the time reached 9 o'clock, the training officially began.
At noon, Gao Zhendong invited the people from the computing office to have a meal. After the meal, they were here anyway, so they would solve the C language matter at noon.
This just gives them no excuse to avoid the afternoon quiz, Gao Zhendong thought a little darkly.
He took a few people to change their shoes and entered the computer room.
People in the computing center saw that there was a program option "C" with a very simple name in Gao Zhendong's cyclic duty environment.
This option is not available in the program provided by Gao Zhendong to the computing institute.
C? What is this? A group of people thought strangely.
But when Gao Zhendong chose to run C and started writing code in it, they understood something.
Director Li and Chief Engineer Chi looked at each other and asked softly: "ALGOL60? Fortran?"
As the top computer experts in the country, they still understand these two things.
They are trying to organize manpower to implement the Fortran language in DJS-59. This language was born from IBM and is suitable for numerical operations. This is very important for people today.
But next, they knew that they had guessed wrong without Gao Zhendong answering.
What Gao Zhendong input is very different from these two languages.
But the two of them could tell that this should be a computer language.
New computer language? ! !
The two suddenly realized what they were looking at.
Calm down, calm down, so what about computer language, maybe it is just a very simple thing with limited functions.
It seems that compared to the first two, this language has a very large degree of freedom.
Because Gao Zhendong doesn’t care how many spaces he enters.
This sounds like a joke. Is the freedom of language determined by a few spaces?
But in fact, this is a kind of evidence.
The computer languages that were born in the early days had very strict requirements for formats. The reason was actually a problem with the entire computer system at that time, which resulted in no way or much ability to handle flexible formats.
What to do? Then just be a programmer.
Write it strictly according to the format!
But Gao Zhendong doesn't seem to be like this. He handles the format very casually.
The two of them were still thinking, but Gao Zhendong had quickly entered three lines of code.
It looks a bit like another implementation of Gao Zhendong's classic "NiHao, ShiJie!"
Indeed, as Gao Zhendong performed several operations, this classic sentence appeared on the screen as expected.
Can three lines solve the problem?
The two realized what they were seeing. This 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.
Achieve everything you want to achieve!
Chief Engineer Chi asked in disbelief: "Director Gao, have you made a computer language? Like Fortran?"
Gao Zhendong nodded: "Yes, also No, it’s called ‘C’, the first letter of our English name in the world.”
