Chapter 341 Missiles and tubes are built
“This group of team leaders will be given priority by the factory when they are transferred or promoted in the future.”
Director Zhang These words are all true, including what I said before about strengthening the security patrol force. The third rolling mill is so big, there are so many people, and there are so many outsiders, and what we are doing now is more and more important. real.
In this sentence, it goes without saying that mentioning cadres means transferring cadres from other sequences to the cadre sequence.
This is a huge temptation for Liu Haizhong. It must be said that Deputy Factory Director Li is very accurate when it comes to people like Liu Haizhong. He can be married to anyone who does anything upright. Put it in firmly.
What's wrong with just two people? When you are in the workshop and you are an old worker, who will listen to you except your apprentice? Are two people no longer human?
Besides, this is just the beginning. When I change my career, I will continue to work all the way up. Am I still worried that there are not enough people in charge?
Lao Liu doesn't know how to criticize and self-criticize, but he still understands comfort and self-comfort, thief!
"Director Zhang, I am willing to lead the new with the old and pass on my experience to the young. This is what I have always wanted to do."
Director Zhang smiled: " Well, okay, I know you old comrades are very enlightened. Now, draw a monogram here, and our security office will handle the subsequent procedures.”
Walking out of the security office, Liu Haizhong was in a happy mood. Although he had to spend all his time in it, without any special benefits, and had to patrol in the hot summer or cold wind with his old leg that had been broken twice, he still had a bright future. It's bright and the future is positive.
On the third day, Gao Zhendong, who was at work, saw Liu Haizhong, who was wearing a red armband, yawning, and leading two young people to patrol in the corner of the factory. The look on his face was still... He's really cool. It would be better if his face wasn't so tired.
Lao Li moves quite quickly, Gao Zhendong thought.
When I arrived at the office, the phone rang. It was Mr. Luo from the Changjian Factory.
"Director Gao, the solid propellant you made is ready."
Mr. Luo didn't know about the third factory, and it was still the old name.
Gao Zhendong was very happy when he heard this. He still thought deeply about this only seedling that survived the drastic measures of the National Defense Working Committee. He was his only son.
"Have you passed the test? How is the situation?"
What he is most concerned about now is this, which is related to the engine modification of his anti-tank missile and barrel.
"It has been done, and the overall situation is not much different from your estimate. For the specific data, I have asked our comrades in the confidential room to send you the test report. I think you can get it in a while Received.”
Now everyone is used to this method, it is convenient and fast.
Gao Zhendong repeatedly praised it, which was half relieved. The difference was not big, so there was no need to make major changes.
"Director Gao, this propellant of yours is amazing. It has a specific impulse that is 10% higher than the similar propellants we have now."
This is normal, fixed propellant. , even thirty years later, it is still one of the stubborn diseases that plagues military equipment. Our missiles are slightly thicker than Citigroup's at the same range.
Therefore, there is no doubt that the original version of the X12, which was derived from the Citigroup individual anti-tank missile of the same period, is better than the existing one.
"Haha, that's good. In this way, the range of our individual anti-tank missiles will be more guaranteed."
The two said a few words and agreed on the direction and nodes of the next step of work. Just hung up the phone.
Not long after, the comrades from the confidential room came over and handed a confidential document to Gao Zhendong.
When I opened it, I saw it was the test report that Mr. Luo mentioned just now.
The explosion heat is 4200kj/kg, the specific impulse is 2200Ns/kg, and the burning rate under 7.12MP is 17~20mm/s, which is in line with my expectations. Although it is a little lower than the original data, this difference is important for the design. It's not a big problem and basically doesn't need to be changed.
After Gao Zhendong saw it, he called Mr. Luo.
"Director Gao, have you read it? Can the engine be processed?" Mr. Luo was very positive.
Gao Zhendong smiled and said: "I've seen it. Your workmanship is very good. It is very consistent with my expectations. There is no need to change the engine. Just process it. Both engines will be processed."
The two engines refer to the engines of individual anti-tank missiles and individual disposable rocket launchers.
For the engine of the anti-tank missile, Gao Zhendong uses a front and rear tandem dual-thrust engine. The rear end uses internal and external fuel columns but the quantity is small. The explosive thrust is large but the combustion is fast and the combustion time is short. It is responsible for moving the missile from Low speed accelerates to high speed in a short time.
The end-burning propellant column used in the front-end propellant column has smaller thrust and slower burning speed, and can provide thrust for the missile to maintain a high speed for a long time. The disadvantage of the end-burning propellant column is that the center of gravity changes drastically during the combustion process. Fortunately, on this projectile, the weight and volume of the rocket engine are not large, and it is located in the middle of the projectile body, so this effect can be basically ignored.
For soft launch, I originally wanted to add a level of thrust, which is used to push the missile from rest to a certain distance from the launcher. Only the minimum thrust is required, but in this way , the propellant filling will be extremely complicated, and there is a certain degree of difficulty from the existing technology, so Gao Zhendong decided to plug in a small booster to solve the problem.
The engine of the individual rocket launcher is much simpler. It has multiple tubes of internal and external combustion charges, reduced surface burning, and free loading. Try to make the rocket burn completely within the length of the launch tube. This is also the 89 barrel method. route.
As for why the telescopic launcher of Citigroup M72 is not used to increase the length of the launcher in the launch state, the main reason is that there is a step in the telescopic launcher, which will greatly affect the accuracy of the rocket. Citigroup’s technology can To solve this problem, the country may not have the ability to do so at this time. Let alone this time, even twenty years later, it will still have an impact.
The 6-piece folding tail on the outside of the engine minimizes the impact of windage, so that no windage correction is added within the effective range.
In addition, before there was any news about the ABS launch tubes and optical plastics from the President, Gao Zhendong also commissioned the Changjian Factory to process a batch of 80mm steel tubes and mechanical sights for use in the plastic launch tubes. used for testing.
As for the picture of the bobbin warhead, it has been sent to the Changjian Factory a long time ago. The charge will be the existing anti-tank missile charge, fuse and connection with the engine. The Changjian Factory will be responsible for solving the problem. .
Mr. Luo was very excited when he heard Gao Zhendong’s affirmative answer. The new missile is taking shape step by step, and judging from the current status, at least its range and speed indicators should be very good. As for the power, it depends on your own factory. ability.
"Okay, Director Gao, I will organize trial production right away. We are all ready and just waiting for your order. We have also obtained enough small gyroscopes for use in missiles, 伱Don’t worry, if everything goes well, we will be able to test full-range telemetry missiles soon.”
This one was copied by Gao Zhendong from Lao Maozi's "baby", and it is similar to the Red Sword-73.
An inertial platform made of a small gyroscope, but this inertial platform does not care about the flight distance of the missile. Its function is not for inertial navigation, but for collecting the flight attitude of the missile and matching it with the information transmitted from the wire. The control signal controls the deflection of the missile at the appropriate time.
Because the gas rudder surface of the "Baby" missile is not always moving. It has four engine nozzles, but only one pair of nozzles has gas rudders, which means it only has a control channel in one direction.
According to legend, this thing uses the roll of the missile to adopt a very clever control method. When the pair of gas rudders roll to the horizontal direction, the gas rudders perform vertical deflection control. When the pair of gas rudders rolls to the vertical direction, the gas rudders perform horizontal deflection control.
Although it looks unreliable, this thing is really accurate, except that the flight path looks a little weird. The advantage is that the control system is simplified and the cost is reduced.
As for how the missile knows whether it is horizontal or vertical, it depends on the gyroscope.
Furthermore, this gyroscope does not move until it is launched. Its starting method will look very crude to future generations.
Just like a yo-yo, the cable is activated. One end of the cable will be fixed on the launch box before launching, and the cable is pulled by the thrust of the missile taking off.
I have to say that when Lao Maozi solves practical engineering problems, he is really very good at solving practical problems. Don’t say these methods are unsound, they can really solve practical problems.
After hanging up the phone, Gao Zhendong returned his energy to his work.
——
Somewhere in the capital, a scientist was looking at a piece of material sent by the National Defense Work Committee with great interest.
The National Defense Work Committee will recently conduct a training called "Equipment Accelerated Testing". Although the scientist does not need to participate in this training, his students are still very keen on the notice issued by the National Defense Work Committee. Found something interesting.
So the student contacted the National Defense Work Committee and successfully obtained this dozens of pages of training materials before the training started.
When the student got it, he saw, oh, sure enough, part of the research content of the teacher and his teacher had good scalability in a certain branch, so he quickly came to the scientist with the materials.
The scientist read the material carefully with great interest and nodded while reading: "Well, it's interesting. Even if the author of this material has not studied control theory, he must be someone in this industry, or even a leader in the industry."< br>
The student smiled and said: "Teacher, I asked about this author's other works. You have seen them before."
Others may not be able to find out, but his Of course the students have no problem, they are just asking about the author of a book, so let’s sprinkle some water.
"Oh? Which one?" Scientists have read a lot of books, so naturally they have to ask to find out.
""Project Management System"! I have attended the training, and the author is a very young scientific researcher."
The scientist suddenly remembered that he had made a pretty good evaluation of that book at that time.
“Okay, very good. It seems that the author has not stopped. He has been studying and thinking hard, and integrated the results into his work. Good! Good!”
