Chapter 546: Still disconnected?

Sha Zhu was so frightened by this look that he turned around blankly for a long time and walked into his house tremblingly.

As soon as I entered the house, I saw my sister looking at me with contempt and uttering a word.

"Coward!"
-
The next day when I went to work, a notice was posted in the factory. The handyman Xu Damao was ordered to reflect on his ideological problems and his salary was cut to the same level as Qin Huairu.

That's not right. Qin Huairu started this month and was higher than him. Although she didn't win the Liehuo Technology Award, she participated in many projects and did a lot of work with Yi Zhonghai in the past year, and was promoted to a regular employee in advance. After the Liehuo Technology Award, the factory started the annual rating. Although she didn't get the second level, she got the first and a half level.

It's hard to get so many upgrades in one year.

Gao Zhendong didn't pay attention to such a small matter. He was talking to Mr. Luo from Changjian Machinery Factory.

With the finalization of the 61 fire and 61 gun family, the time for finalizing the anti-tank missile is also approaching.

"Now that we have switched to infrared tubes with a specific wavelength, what is the effect?"

The original infrared goniometer was very susceptible to interference from the engine's tail flame, resulting in a poor hit rate before the engine burned out. Gao Zhendong suggested that they use infrared light-emitting tubes and infrared photosensitive elements with a wavelength that was very different from that of the engine's tail flame.

——HgCdTe sensor with specially modulated composition.

However, the manufacture of mercury cadmium telluride crystals is very time-consuming. Since a photosensitive element with a specific wavelength is required, the already manufactured mercury cadmium telluride crystals cannot be used and new ones have to be made.

Although under the guidance of Gao Zhendong, Yu Yuncheng and his team adjusted the recrystallization time of the mercury cadmium telluride crystals, the entire process still took more than 1761 days. So since Gao Zhendong made suggestions for improvement last time, although and Changjian Machinery Factory worked hard and all manufacturing processes and testing links were carried out without stopping, it still took more than a month to complete the task.

Mr. Luo rushed here today, not only to report on the progress, but also for this matter.

Speaking of this, Mr. Luo was very happy: "Very good, the close-range performance has been greatly improved. We have finally brought the close-range hit rate to the average level. Now the overall hit rate is 80%, which is basically the same in all stages, with little fluctuation."

The first generation of anti-tank missiles with manual control had a very poor close-range hit rate, 60% was considered normal. If the distance was too close, the shooter would not be able to adjust at all, or he would over-adjust due to excitement.

The second-generation missiles that use line-of-sight semi-active guidance have a much better hit rate. You only need to aim along the line of sight and leave the rest to the system.

The individual anti-tank missile that uses an infrared goniometer has a standard semi-active aiming line. Although due to the current technical status, it is still some distance away from the hit rate of Gao Zhendong's previous second-generation missile in an interference-free state, but compared with the missiles of the same period, it is really a great shot.

"Do you have any other questions now?"

"Nothing has been found so far. The hit rate, power, carrying performance, and maintenance performance have all been tested internally, and no problems have been found."

Gao Zhendong nodded, and it seemed that we could take the next step.

"Then you can do the accelerated life assessment test on yourselves first, and prepare to send it to the Syracuse Test Center and trial troops in various places."

Accelerated lifespan assessment technology can indeed accelerate the process, but it still takes some time, so it can be arranged.

Before this technology was available, it could have been sent to Xuecheng for trial use at this stage. However, now that we have this technology, it is better to try it myself first. If there are any problems, they can be corrected to avoid wasting the experimental funds and resources there.

More haste, less speed, and since this anti-tank missile was launched so far in advance, there is plenty of time.

"Well, after using the new goniometer, we have been preparing for it, and it is estimated that it has been carried out now."

Mr. Luo and his team are very experienced in this area and have been prepared for it for a long time.

At this point, Mr. Luo hesitated, as if he wanted to say something but didn't know how to say it.

Gao Zhendong noticed it very keenly and asked directly: "What's the matter? Is there anything you want to say? Just say it, don't worry."

Mr. Luo thought for a moment and said, "A few days ago, I went to the Defense Work Committee to do some work and heard some news about the vehicle-mounted heavy bombs."

Vehicle-mounted heavy bombs? If Mr. Luo hadn't mentioned it, Gao Zhendong would have almost forgotten about it.

The reason why Changjian Factory developed this missile was that Gao Zhendong opposed the imitation of SS.11 and proposed to develop an individual anti-tank missile first, but to no avail. Then Changjian Factory had an idea and took the initiative to contact the National Defense Working Committee, Gao Zhendong and the troops, and was determined to raise funds on its own.

As a result, the bomb was basically carried out smoothly all the way, and Gao Zhendong had long forgotten about the vehicle-mounted heavy bomb.

That missile is destined to fail, but it doesn't mean it cannot be copied. I guess it is possible with a little more time.

But copying does not mean success. The object of copying, SS.11, originally had congenital defects. Although Gao Zhendong helped solve the biggest problem - the problem of control law in the womb, it is estimated that it can be hit more accurately now.

However, the SS.11 itself is like that. If you imitate it, you will find that all the indicators of the vehicle-mounted heavy bomb are on par with or even worse than the individual anti-tank missile developed by Gao Zhendong and his team, but the weight of a single bomb exceeds that of the entire system of the individual bomb. So this heavy bomb cannot be finalized anyway.

But now that he heard Mr. Luo talking about this, Gao Zhendong became a little interested. Mr. Luo would not bring up this matter for no reason. "Ah, the one that copied the Gallic SS.11? I remember it now. How is it going? Is the copying going smoothly?"

Sure enough, Mr. Gao had completely forgotten about this thing and didn't take it seriously at all.

Mr. Luo frowned and said, "It's not going well. I don't know anything else, but I know that it's still disconnected until now."

"It's still disconnected? That shouldn't be the case." Gao Zhendong was a little surprised.

"We didn't buy the other side's missiles. We just copied them with this small batch of samples. Naturally, we don't have any technical information. The wire looks simple and its composition seems to be clear, but the one we made broke at a speed of 220 meters."

Compared with the previous technological accumulation, the flying speed of SS.11 was still too fast, far exceeding the speed of the anti-tank shell that was originally used as a prototype. The technological accumulation could not be used, and the object of imitation was not understood, so it was stuck there.

In fact, Mr. Luo knew about this matter when Gao Zhendong was helping them solve the problem of the broken string of the bullet. However, even though he knew it, taking the initiative to approach him would easily cause misunderstanding, so there was no follow-up.

What I never expected was that after so much time had passed, it was still interrupted.

"Didn't they think of a solution?"

"After thinking about it, they wanted to add steel wire to the conductor, but the steel and wire processing technology were limited, and they couldn't pull it that thin. It took a lot of time, and either the weight exceeded the standard, or it was still not strong enough and broke," Mr. Luo explained.

This is a problem. Gao Zhendong finally understood why it took Chijian-8 a long time to solve this problem.

"How do you know about this?" Gao Zhendong was a little surprised. Although they were all working on anti-tank missiles, according to discipline, he could not find out this information.

"I heard it from a comrade from the Defense Working Committee." Mr. Luo was also a little puzzled.

"Unintentionally?" Gao Zhendong didn't think too much about it and asked Mr. Luo: "Do you mean to help?"

"Yeah, yes, yes, that's what I mean. It's not a good thing to keep wasting national resources like this." Mr. Luo's idea was the same as Gao Zhendong guessed. They were both working hard for work and to protect this land.

There is no point in hiding it and waiting to be slapped in the face. Imitation of vehicle-mounted heavy ammunition is also a scientific and collective decision. It's just that Gao Zhendong has reservations.

But reservations aside, neither Gao Zhendong nor the Changjian Factory could do it as they watched the heavy-bullet projectile team get stuck in a dilemma and unable to move forward.

Besides, it’s actually quite satisfying to help solve problems, haha.

Gao Zhendong nodded: "Well, I agree with you, but I suggest you pay attention to the skills."

Sure enough, Mr. Gao doesn'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 Defense Work Committee, and the rest will fall into place naturally."

Gao Zhendong laughed, this made sense.

At the Defense Work Committee, after receiving the conductor technical information from the Changjian Factory, the committee's chief engineer took it to the leadership.

"Leader, you guessed it right. There is no need to say more. Gao Zhendong and Changjian Factory sent the information as soon as they received the news."

"You don't know Gao Zhendong yet? He will give you whatever you want as long as he has it. He didn't make any move in the front. I guess he didn't know about it, and he was afraid that the comrades who were engaged in the heavy shells would be suspicious. The comrades who were engaged in the heavy shells were the same. They just held on like this. Their face was killing them."

The Commission's Chief Engineer laughed and said, "I guess they don't know that there are comrades who have solved this problem, hahahaha."

The leader smiled and said, "Confidentiality is necessary. The lack of information that comes with confidentiality is also a necessary price to pay. This is when we should play our role. Send it to the heavy bullets as soon as possible. I feel anxious for them."

In a machinery factory, comrades from the factory research institute are holding a very thin wire, examining it carefully, and discussing it.

"We have tried every possible way and spent a lot of time, but the line is still broken!"

"With the Heilongjiang Hun-60, the armor-piercing power is catching up with the Gallic Rooster, but this guidance system has problems even with normal tests. We can't move forward at all."

With the decline in the demand for Heihun-60 in the desert and the increase in the production of Heihun-60, it can finally flow out and be used with other ordinary ammunition. This can be regarded as solving the first obstacle of the heavy ammunition group - power.

With the introduction of the Black Mix-60, the penetration depth, which was originally far behind, is finally on par with the SS.11.

However, the test of the guidance system was extremely unsuccessful. Up to now, the most basic thing - the wires are still broken. As for whether the guidance system itself is well made and accurate, that is even more difficult to say. There are too many broken wires, making it difficult to evaluate.
