Chapter 506 The small tail of the anti-tank missile
Director Yan happily took the list to purchase goods, while Gao Zhendong put this matter aside and started to deal with technical work.
The Northeast Optics Institute has completed the transformation of the optical system and sent it over. By the way, a person has also come to be responsible for cooperating with the installation and debugging of the optical system.
The old craftsmen in the factory temporarily put aside their work of further improving the positioning accuracy of the workpiece table and started assembling the photolithography machine.
It is said to be assembly. In fact, a more appropriate term should be trial assembly. Gao Zhendong only proposed the installation requirements and main structures. The specific details have to be explored bit by bit by the master craftsmen. point modification, so the progress is relatively slow.
Fortunately, the lithography machine at this time was actually a relatively simple thing. It was so simple that if people in later generations who were not professionals in the related field saw it, they would never associate it with the lithography machine.
Gao Zhendong’s lithography machine is even simpler, using manual film feeding, manual alignment, and automatic exposure.
Although simple, it still takes time, especially when many small parts, components, and connectors need to be adjusted by hand. Among them, there are a lot of details that need to be modified and confirmed by Gao Zhendong. Urgently There's no rush.
Gao Zhendong was working hard and skillfully with the comrades of the No. 3 Factory. Someone came to see him. To be precise, they had wanted to find him for a long time, but they had been waiting for him to go to work.
Mr. Luo from Changjian Machinery Factory is here.
As soon as Mr. Luo came over, he first brought good news. Although it had been expected for a long time, this time the dust had settled, which could be regarded as letting go of something.
——The disposable rocket launcher has been officially finalized.
After field use by multiple units in many places, and simultaneous formal testing at the Syracuse Experimental Center, the disposable rocket launcher was finally named the "1961 Anti-Tank Rocket Launcher" and was officially installed. According to convention , referred to as "61 Fire".
A total of 400 rocket launchers were fired in this formal test in Syracuse. The test was extensive and took into account various situations in use.
At the same time, in accordance with the latest requirements of the National Defense Work Committee for equipment finalization, Syracuse also carried out an equipment accelerated experimental evaluation of disposable rocket launchers. The test showed that the 1961 anti-tank rocket launcher using the Black Mix-60 , fully meeting the reliability and storage requirements during the design life cycle.
"Mr. Gao, now our factory has begun to increase equipment and manpower, and has begun to produce 61 fire."
Changjian Machinery Factory was originally engaged in fuses. If it wants to produce 61 fire, it needs to update a batch of equipment. .
"It has been handed over to you? What about the comrades who originally produced 40 fires?" Gao Zhendong was a little surprised.
In this timeline, there is no "New 40 Fire", so the old 40 Fire is simply referred to as 40 Fire. It's interesting to say that the abbreviation of 40 fire comes from the caliber, while the abbreviation of 61 fire comes from the year.
Mr. Luo smiled and said: "I heard that they will continue to produce, and there will be no impact on both sides. They occupy the establishment, and ours does not occupy the establishment, so for the time being, how to produce and distribute is still the same as before. Moreover, I heard that they still have foreign aid tasks to complete.”
After listening to his words, Gao Zhendong understood. It was probably that the comrades in the army were also a little frightened by the power of 61 fire. And judging from the current struggle situation, 40 fire was completely enough, so 61 fire still had to hold on to its own people first. Come.
This is definitely not the monkey version of foreign aid. The power of 40 fire in foreign aid is the same as 40 fire for self-use. Where is the monkey? It doesn't exist, okay.
Mr. Luo smiled happily and applauded his factory's decision to seize the opportunity last year, make a determined decision to fight against the odds, seize the opportunity given by Mr. Gao, and decisively participate in the research of individual anti-tank missiles.
Let’s not talk about the anti-tank missiles that are about to be successful. Even the scraps of prototype prototypes that were thought to be just a warhead at the beginning have now developed into a formal equipment with great power and excellent performance.
The other purpose of his coming today is precisely for this individual anti-tank missile.
"Mr. Gao, in addition to bringing you this good news, there is another thing I came here to do today, about individual anti-tank missiles."
Gao Zhendong was not surprised. The anti-tank missile has been in development for so long, and with its own warhead, guidance system, and rocket engine as the foundation, plus the efforts and experience of the comrades at the Changjian Factory, it is almost time to bear fruit.
"Anti-tank missiles? I remember you were solving the problem of small gyroscopes in the tail of the missile some time ago, right? How is the situation?"
"The problem of small gyroscopes has been basically solved. The 11th Machinery Department has provided improved processing equipment, and the processing accuracy has been improved. The situation is good now. This time, it is for the guidance system.”
There is progress again, not bad, Gao Zhendong said with a smile. : "Tell me about it." "During the experiment, we found a problem. It is not fatal, but it will have a certain impact on the hit rate, so we want to see if we can further improve and optimize it. If the technical support cannot be supported temporarily, or The cost is too high, so forget it, after all, the hit rate now meets the requirements.”
This is a common problem among technicians, or stubbornness. Although I have reached the standard, I seem to have found a way to improve it a little bit, so let’s try it? Don't give up if you don't try.
However, Mr. Luo is still very sensible. In addition to the exception that the technology cannot support it, he also soberly adds the condition that the cost is too high.
“What problem did you find?”
“That’s right, although in terms of structural design, the infrared tracer tube at the tail of the missile is arranged as misaligned as possible with the engine nozzle in the middle of the missile body, and as far as possible The luminous color is different from that of the engine jet. However, since the jet of engine gas is diffused and the light itself is scattered, the firelight when the engine is working far exceeds the brightness of the tracer tube. In this way, the light emitted by the engine is diffused. Light and infrared rays will interfere with the infrared goniometer, causing a certain degree of inaccuracy, and the closer the distance, the more obvious it will be.”
Gao Zhendong thought about it and realized that this was indeed a problem.
If the human eye can judge the deviation between the missile position and the target through the tracer tube, no matter how big the fire is, people can basically judge the accurate missile position through brainstorming, then the automatically captured infrared goniometer can When the conditions are not ideal or the device performance is insufficient, there is absolutely no solution.
Although this system on the human head is not very accurate, in terms of practicality, it is very powerful. Nowadays, these ancient-level automatic control systems are really incapable of beating the human head when the sensors, algorithms, computing cores, and even no computing cores are still imperfect.
As for the reason why the closer the distance is, the more inaccurate it is. The closer the distance, the greater the engine fireworks and the greater the interference. The farther the distance, the smaller, and even the engine will not work after burning out. Yes, it's okay.
The engine sings: I am who I am, a firework of different colors~~~~~
This is the truth, but in the eyes of others, the closer it is, the more inaccurate it is. This is not a joke.
However, this matter is not difficult for Gao Zhendong, he has the goods.
"Well, this problem is not difficult to solve. In this way, after you go back, take an infrared spectrum of the engine flame and see which section of the infrared spectrum is the weakest."
Mr. Luo Follow Gao Zhendong's train of thought and think: "Which section is the weakest? The weakest...the weakest...Mr. Gao, I understand, you want to put the infrared characteristic wavelength of the infrared tracer tube where the engine flame is the weakest..." Which section? This can avoid interference to a large extent? "
The phenomena of infrared rays of different wavelengths look similar, but the essence is different. Just like the Samba National Football Team and the Eastern University National Football Team in the 21st century, they were both scored 7 goals by the S2 Axis, but can we say that the two are on the same level? Obviously not.
This is why Mr. Luo likes to find Gao Zhendong. In addition to always being able to solve problems, he can also get a lot of inspiration.
Gao Zhendong nodded: "Yes, that's what I mean. Use characteristic wavelengths to distinguish the engine flame and the infrared tracer tube. In this way, the infrared goniometer can figure out who is who without the need for the human brain. "
Mr. Luo was overjoyed: "Okay, this method is good, it is not technically difficult, and it will not increase the cost too much..."
As he spoke, he discovered A new question was asked: "But Mr. Gao, how does the infrared goniometer capture this characteristic wavelength? It doesn't have this ability."
Gao Zhendong said: "You first capture the characteristic wavelength, do you remember Mercury cadmium telluride infrared photosensitive material? ”
"Well, remember, this is a good thing. If the thermal imaging camera you bought was not too expensive, I would have installed it on the sight, but..." Speaking of this, Mr. Luo was very excited and yearned for it.
Gao Zhendong smiled and said: "Thermal imaging cameras are too expensive, but it is still possible to use cadmium mercury telluride as an infrared goniometer. It is not that expensive, and this goniometer can be reused. The problem Not big. Moreover, one advantage of mercury cadmium telluride is that its sensitive band can be adjusted by adjusting the components."
Why did Gao Zhendong start working on a new generation of infrared photosensitive materials? At that time, there was no choice of indium antimonide, which was used more in third-generation air-to-air bombs? This is the reason. Cadmium mercury telluride is soft and adaptable. When resources are limited and cannot be used all, cadmium mercury telluride is stronger than indium antimonide.
Who will you choose, Dark Phoenix or Mystique? Gao Zhendong chooses Mystique.
When Mr. Luo heard this, was there such a benefit? That’s okay, I’ve decided on the original 70% hit rate!
This hit rate is not bad. Originally, Red Sword-73 only had this hit rate from the beginning. It is mainly because of this hit rate. It is negatively related to the range, which makes it difficult to tighten it. It's counterintuitive. Take it out. Even if you say it, you will be laughed at.
Mr. Luo closed his notebook: "Mr. Gao, I understand! I will go back and organize the manpower to spectrum the missile's engine flame!"
As long as they determine the required sensitivity Band, the only thing left is for Gao Zhendong to inform 1761 to adjust the material composition.
