Chapter 546: Still disconnected?
Si Zhu was so stunned by this sight that he turned around blankly for a long time and entered his house tremblingly.
As soon as he entered the house, he saw his sister looking at him with contempt and uttering a word.
“Cowardly!”
——
When I went to work the next day, a notice was posted in the factory. Xu Damao, the handyman, was ordered to reflect on his ideological problems. He paid as much as he could and became the same as Qin Huairu.
That's not right. Qin Huairu is higher than him starting this month. Although she doesn't have a share in the Liehuo Science and Technology Award, she has participated in many projects with Yi Zhonghai in the past year, done a lot of work, and became a full-timer ahead of schedule. . After the Agni Technology Award, the factory started its annual rating. Although she hadn't been able to reach level two yet, she had level one and a half.
How can there be so many things like going up one level a year? It’s very difficult.
Gao Zhendong didn't pay attention to such small things. He was discussing things with Mr. Luo from Changjian Machinery Factory.
With the finalization of the 61 fire and 61 gun families, the time for the finalization of anti-tank missiles is also approaching.
"What is the effect after switching to an infrared tube with a specific wavelength?"
The original infrared goniometer is very susceptible to interference from the engine exhaust flame, resulting in an ugly and high hit rate before the engine burns out. Zhendong suggested that they use infrared light-emitting tubes and infrared photosensitive elements that have different wavelengths from the engine tail flame.
——Mercury cadmium telluride sensor with specially modulated composition.
However, the manufacture of mercury cadmium telluride crystals is very time-consuming. Since a photosensitive element of a specific wavelength is used, the already manufactured mercury cadmium telluride crystals cannot be used, and new ones must be made.
Although under the guidance of Gao Zhendong, Yu Yuncheng and the others adjusted the recrystallization time of the mercury cadmium telluride crystal, it still takes about twenty days to complete the entire process, so since the last time Gao Zhendong mentioned After the improvement suggestions were made, although 1761 and Changjian Machinery Factory worked hard, and the manufacturing processes and testing links were non-stop, it still took a month to get this thing done.
Mr. Luo came here today. In addition to reporting on the progress, a small part of the reason was also for this matter.
Mentioning this, Mr. Luo was very happy: "Very good, the close range has been greatly improved. Finally, the hit rate at close range has been brought to the average level. Now the overall hit rate is 80%. , basically the same in each stage, with little fluctuation. "
The hit rate of the first-generation anti-tank missile that uses manual control is very ugly. 60% is considered normal. The distance is too close and the shooter cannot adjust it at all. , or overshoot when excited.
The second-generation missile that uses line-of-sight semi-active guidance has a much better hit rate. It only needs to be aimed at the line-of-sight, and the rest is left to the system.
The individual anti-tank missile using an infrared goniometer is the standard semi-active sighting line. Although due to the current technical problems, the target hit rate of Gao Zhendong’s previous second-generation missile without interference is still far away. Some distance, but compared with the missiles of the same period, it is really a hanging shot.
"So are there any other problems now?"
"No problems have been found yet. The hit rate, power, portability performance, and maintenance performance have all been tested internally, and no problems have been found."
Gao Zhendong nodded, it seems he can take the next step.
"Then do yourselves the accelerated life evaluation test first, and prepare to send it to the Syracuse Test Center and various trial troops."
The accelerated life evaluation technology can indeed speed up, but it still needs to be If you have some time, you can arrange it.
When this technology didn’t exist before, it could already be sent to Syracuse and tried out at this stage. However, now that this technology is available, it’s better to try it yourself first, so that if there is any problem, it can be corrected, so as not to waste the testing funds and money there. resource.
Haste makes waste, and with this anti-tank missile being launched so far in advance, there is plenty of time.
"Well, after testing with the new goniometer, we are already making preparations, and it is estimated that it has already started."
Mr. Luo and the others are very experienced in this area, so early Just ready.
Speaking of this, Mr. Luo was a little hesitant, as if he wanted to say something but couldn't say it.
Gao Zhendong noticed it very keenly and asked directly: "What? Is there anything you want to say? Just say it, don't worry."
Mr. Luo thought for a while and said: "A few days ago I went to the National Defense Work Committee to do some work and heard some news about vehicle-mounted heavy-duty ammunition.”
Vehicle-mounted heavy-duty ammunition? Had Mr. Luo not mentioned it, Gao Zhendong would have almost forgotten about it.
Changjian Factory developed this bomb because Gao Zhendong opposed the imitation of SS.11 and proposed to develop individual anti-tank missiles first, but to no avail. Changjian Factory was blessed and took the initiative to approach the National Defense Working Committee, Gao Zhendong and the troops. There, self-raised funds will also have to be raised.
As a result, the project went smoothly all the way. Gao Zhendong had forgotten about the vehicle-mounted heavy projectile a long time ago.
That bomb is destined to be impossible to make. It doesn't mean that it can't be copied. I guess it will be possible if it takes more time.
However, imitation does not mean success. The imitation object SS.11 was inherently deficient. Although Gao Zhendong helped solve one of the biggest problems - the control law problem in the mother's womb, it is estimated that it can be more accurate now.
But the SS.11 itself looks like that. When you imitate it, you will find that all the indicators of the vehicle-mounted heavy-duty missile are on par or even worse than the individual anti-tank missiles developed by Gao Zhendong and others, but the weight is the same. The weight of a single bomb exceeds the entire system of individual ammunition, so this heavy-duty bomb cannot be finalized no matter what.
But now that Mr. Luo talked about this matter, Gao Zhendong became a little interested. Mr. Luo would not mention this matter for no reason. "Ah, the one who imitated the Gallic Chicken SS.11? I remembered it. How is the situation? Is the imitation going well?"
Sure enough, this thing was completely forgotten by Mr. Gao, and he didn't take it seriously at all.
Mr. Luo frowned and said, "It's not going well. I don't know anything else. I just know that the connection is still disconnected until now."
"It's still disconnected? It shouldn't be. ." Gao Zhendong was a little surprised.
“We didn’t buy each other’s missiles, we just copied them with a small batch of samples. Naturally, we didn’t have any technical information. The wire looked simple and its ingredients seemed clear, but we made it ourselves. The disconnection at a speed of 220 meters is very serious. "
Compared with the previous technological accumulation, the flying speed of SS.11 is still too fast, far exceeding the anti-tank bullet that was originally developed. At such a speed, the technology accumulation cannot be used, and the imitation target cannot understand it, so it gets stuck.
In fact, Mr. Luo knew about this matter when Gao Zhendong helped them solve the disconnection problem of the bullet in his hand, but he knew that he knew that taking the initiative to get involved would easily cause misunderstandings, and there would be no follow-up.
What I never expected is that time has passed for so long and it is still breaking.
“They didn’t think of a way?”
“They thought about it. They wanted to add steel wires to the wires, but the steel and steel wire processing technology was limited and they couldn’t pull it so thin. It took a lot of time. , either the weight exceeds the standard, or it is not strong enough and the wires break," Mr. Luo explained.
This is a problem. Only then did Gao Zhendong understand why Red Sword-8 spent a lot of time solving this problem.
"How do you know about this issue?" Gao Zhendong was a little surprised. It was said that although they were all working on anti-tank missiles, according to discipline, he would not be able to find out this information.
"I heard the comrades from the Defense Working Committee accidentally mentioned it." Mr. Luo was also a little confused.
"Accidentally?" Gao Zhendong didn't think too much and asked Mr. Luo: "You mean to help?"
"Well, yes, yes, that's what I meant. It's not a big deal to waste national resources like this." Mr. Luo's thoughts were the same as what Gao Zhendong guessed. They were all working hard to protect this land.
There is no point in hiding and waiting for a slap in the face. Imitation of heavy vehicle-mounted ammunition is also a scientific and collective decision, but Gao Zhendong only has reservations.
However, reservations remain reservations. It is difficult for Gao Zhendong and Changjian Factory to sit back and watch the heavy bomb research team get into trouble.
Besides, it’s actually pretty cool to help solve problems, hehehe.
Gao Zhendong nodded: "Well, I agree with you, but I suggest you pay attention to your skills."
As expected, Mr. Gao didn't care about this matter at all.
Mr. Luo smiled and said: "Okay, my idea is to send this part of the technical information directly to the National Defense Work Committee, and the rest will naturally fall into place."
Gao Zhendong laughed, what he said made sense.
At the National Defense Work Committee, after receiving the wire technical information from the Changjian Factory, the chief engineer of the Committee took this thing to the leadership.
"Leader, you guessed it right. No need to say more. Gao Zhendong and Changjian Factory received the news and sent the information."
"Gao Zhendong, you don't know yet. ? As long as he has what he has, he will give him whatever he wants. I guess he doesn't know, and secondly, he is afraid that the comrades who are engaged in heavy bombing are also too careless. It’s killing people.”
The committee chief worker said with a smile: “I guess they don’t know any comrades have solved this problem, hahaha”
The leader smiled and said: "Secrecy is necessary, and the lack of information caused by secrecy is also a necessary price. At this time, we should play our role. Send it to Zhongbang quickly. I feel sorry for you when I see it. They are anxious. "
In a certain machinery factory, comrades from the factory's research institute are holding a very thin wire, looking at it carefully, and discussing.
“I have tried all the methods and spent a lot of time, but the line is still broken!”
“Seeing that with the Black Mix-60, the armor-piercing power is comparable to that of the high-end Luji’s goods are available, but this guidance system is problematic even for normal testing, and it is impossible to move forward.”
With the decline in demand for Heihan-60 in the desert, and the Heihan-60. The increase in output of 60 can finally flow out, allowing other ordinary ammunition to be used. This can be regarded as solving the first obstacle to the heavy ammunition group - power.
With the Hei Hun-60, the penetration depth, which was originally a bit off, is finally on par with the SS.11.
However, the test of the guidance system was extremely unsatisfactory. The most basic thing - the wires are still broken. As for whether the guidance system itself is well done and whether it is accurate, it is even further away. There are so many lines that it's hard to evaluate.
