Chapter 386 Don’t talk!

They still believed in Gao Zhendong's words. This comrade not only understood technology but also had tactics. He was also very rigorous and would not play tricks.

The comrades of the Flying Army sat down happily and started thinking about tactics in their minds. With this thing, the original set was obviously not enough. The scientific researchers handed them a good knife, but if they didn't have good knife skills to match it, they would wish they could find a piece of tofu and kill themselves.

In fact, their original idea was that as long as they had it, it would be fine. If the performance could not catch up with others, they would find a way to make up for it with combat skills. Fighting a battle with inferior equipment would take time, not just one or two days, but also one or two years. They were used to it.

Comrades in the army are always used to finding ways to solve problems on their own, just like the big pipes and various field air defenses of the army that were far superior to those of the same level of troops in the United States. Their starting point was to solve all problems by themselves without relying on comrades flying in the sky.

I never expected that there would be so many wars to fight.

They are targeting more than just the P-2V.

After everyone had expressed their opinions, the leader of the Defense Work Committee began to play the role of presiding over the meeting: "Comrades, everyone has understood the situation. Comrades from the expert group, please discuss whether you agree to enter the finalization process for the imitation air-to-air infrared combat missile."

All the experts present raised their hands. Are you kidding me? If this can’t be finalized, then what else can be finalized?

Including Gao Zhendong, although he knows better, he has to look at the era this is. This thing can guarantee to crush the opponent.

Only the chief designer of the missile design institute felt that it was a little lacking: "Thank you for your recognition and support for our work, but this missile does not have forward attack capability and is seriously affected by the sun. It is really a pity."

Deep down, he actually felt that these things were all imitations. The parts that were better than others were not his own, or they were not original to his institute. It always felt that they were not perfect.

But others don’t know. What’s the matter? You still feel it’s not enough, comrade? You are taking advantage of the situation and being ungrateful.

It's so much better than the Russians, and you still feel regretful? That's a bit too much.

No one else could explain it, only Gao Zhendong laughed.

He knew what was wrong with this thing. In addition to the sensor, the problem was also with the working principle of the guidance head.

The sensor only determines one part, and the working principle of the seeker detection and guidance is another part.

Without changing the sensor, just changing the working principle may not necessarily enable forward attack, but improving the rear-end pursuit and anti-interference capabilities should not be a problem.

As for why he knew this? This involves that in addition to quarreling with each other in his previous life, he wanted to study for a master's degree, and he had to learn about the school and major he wanted to study for.

Hearing Gao Zhendong's laughter, everyone in the first row looked at him.

The people at the Institute of Advanced Studies were thinking quickly and looked surprised.

But the leaders of the Defense Work Committee and the chief engineer had alarm bells ringing in their heads, huh?
Gao Zhendong continued: "This question, too..."

As soon as he said this, the leaders of the Defense Work Committee knew what he was going to say next, which was probably something like "It's not unsolvable" which was not difficult to understand at all, plus some technical suggestions that might be more difficult to understand. Then the meeting room was filled with a happy atmosphere. The only problem was
——You can’t talk about this in front of so many people!

The leader of the Defense Work Committee shouted, "Don't talk!"

This sound startled everyone. What mistake had this comrade made that he was not even allowed to speak? He just laughed a few times.

Except for a few people, they were very happy. It came, it came, the good stuff was coming again. It seemed that they had to have a small meeting with the senior consultant later.

After the leader finished shouting, he slowly added: "Comrade Zhendong, we will talk about other things later. Let's talk about the finalization first."

It's all settled, what else is there to say? But Gao Zhendong also realized that there were probably too many people and he couldn't say anything, so he quickly shut up.

The leader breathed a sigh of relief. This kid was just as the chief engineer said, his head was full of ideas, and they couldn't be stopped from popping out. If you weren't careful, problems would arise.

But he was also itching in his heart. What method did Gao Zhendong have to further improve the performance of the seeker? Once Gao Zhendong opened this loophole, some people who knew the ins and outs of the matter were itching in their hearts, and they couldn't help it.

Against this background, everyone quickly passed the final resolution of the meeting.

——The imitation infrared combat missile was named Thunderbolt-1 and entered the formal finalization process. At the same time, without waiting for the finalization, the Institute of Missile Research provided three complete combat systems and a certain number of trial missiles to a modification factory of the Flying Army for early trials.

After the meeting, the comrades from the Institute of Guidance and Research immediately fixed their eyes on Gao Zhendong. Before Gao Zhendong stood up, the chief engineer of the Defense Work Committee smiled and said, "Comrade Gao Zhendong and comrades from the Institute of Guidance and Research, please stay for a while. There are other things to discuss."

Gao Zhendong entered the next meeting without even moving his butt. This meeting did not happen originally, but he created it himself.

After all those who needed to be cleared out had done so, only the leaders of the Defense Work Committee, the Chief Engineer, comrades from the Research Institute, and Gao Zhendong were left.

The leader of the Defense Work Committee smiled and said, "Okay, Zhendong, you can say whatever you wanted to say just now. I am also very curious about what you want to say."

The comrades from the Institute of Guidance and Research also looked at him eagerly. Gao Zhendong really wanted to say "forgot", but that would be too much of a joke.

He nodded. "What I was trying to say is that it is not impossible to solve the problem. It just takes a little time, and the cost of missiles will increase."

As expected! Everyone felt that this was exactly what they expected.

"Counselor Gao, if you have any solution, please give me some guidance."

The leader also nodded happily: "Well, let's talk about it first, let's not worry about the cost first."

Gao Zhendong didn't think about putting line-scan thermal imaging on missiles right now. Not to mention that it hasn't been done yet, the price of that thing is extremely expensive. It's acceptable to put it on reusable equipment like tanks, but it would be too wasteful to put it on missiles.

But he had an alternative.

He nodded: "Okay, if I remember correctly, I have seen the guidance head materials provided by the Guidance Research Institute. You use an AM modulation disk for guidance, right?"

This involves the working principle of the seeker.

Many people are not aware of one problem. For early seekers, the infrared sensitive element is a whole piece, and it is integrated. No matter where the infrared light shines on its surface, it will output a signal related to the intensity, but it is actually impossible to determine the direction of the signal source.

How does the infrared seeker know the direction of the signal?
This brings us to the working principle of the point source seeker. There are many types, but Gao Zhendong knows that AIM-9B, K-13, and Thunder-2 all use the same type - an amplitude modulation disc seeker.

The details are quite complicated. To put it simply, this method adds a shielding disk - a modulation disk - in front of the infrared sensitive element. There is one or more light-transmitting areas on the disk from the center to the outside. This shielding disk will rotate, and when the light-transmitting area turns to the area where the infrared signal is located, the infrared signal will be projected through it onto the infrared sensitive element.

In this case, the direction of the point source signal can be known based on the rotation position of the modulation disk.

This method is very clever. It converts the detected target direction into reading the rotation position of the modulation disk. The modulation disk is controlled by the guidance system and its position is easy to determine. In this way, the problem of determining the target direction is solved.

It sounds simple, but it is actually more complicated.

After hearing Gao Zhendong's question, Engineer Lu from the Institute of Directed Research nodded and said, "Yes, the AM modulation disk."

He is responsible for the guidance system and is also Lin Lianwei's leader.

Gao Zhendong said: "The AM modulation disk will naturally block at least 50% of the signal, which is extremely disadvantageous for detection sensitivity. And this mode has a huge flaw, that is, when the infrared light source moves toward the center of the modulation disk, the modulation signal will weaken and be zero at the center, right?"

This is the biggest problem with this principle. The detection performance is already poor, and the signal is cut by at least half. Moreover, the more accurate the alignment, the worse the signal. When is the alignment? When there is no signal.
Damn, there is no signal even when the phone is unlocked!
This may seem like dark humor, but it's the truth.

Engineer Lu nodded somewhat awkwardly: "There is this problem, but we haven't figured out a solution yet."

Not to mention now, even in Gao Zhendong’s previous life, the food was not improved until the 80s, and by then the day lily had become completely unpopular.

It seems like a very simple principle, but we haven't improved it in decades. It sounds fantastic, but this is the reality.

Fortunately, Gao Zhendong knows the principle, and there is more than one.

But he decided to skip those in the middle that he knew had problems, and jump directly to one of the ultimate solutions before the infrared focal plane array came out.

Gao Zhendong had to use a pen at this time, otherwise he would not be able to explain how the following things came about.

"When I saw the guidance principle used by the comrades in the Institute of Navigation and Research, I realized that this principle made the already limited infrared detection capability even worse, so in my spare time, I also thought about how to solve this problem."

When these words were spoken, everyone stood in awe, including the people from the Defense Work Committee.

Comrade Gao Zhendong's spirit is so selfless. You should know that the work of the Research Institute is not his main job, and it is not even a serious job. No matter how busy he is with his own work, you don't need to look at anything else, just look at the results.

Even in this situation, he still took time out to devote himself to the guidance of air-to-air missiles.

The leader of the Defense Work Committee didn't know what to say: "Zhendong, you..."

Asking him not to work or to work less is unrealistic and hard to do.

Gao Zhendong smiled and said something that made everyone drop their jaws.

"I considered three or four principles, and finally decided that orthogonal quaternion detection was the most appropriate."
