Chapter 386 Don’t talk!
They still believe Gao Zhendong’s words. This comrade understands both technology and tactics. He also has a very rigorous personality and does not play tricks.
The comrades of the Flying Army sat down happily and began to think about tactics. With this thing, the original set was obviously not enough. The scientific researchers handed over a good knife. If there is no good knife If the law doesn't match, then they wish they could find a piece of tofu and hit them to death.
In fact, their original idea is that as long as they have it, it will be fine. If the performance cannot catch up with others, then they can find a way to make up for it with combat skills. Fighting a battle with inferior equipment does not take a day or two, or a year or two. , get used to it.
Comrades in the army are always used to finding ways to solve problems on their own, just like those in the army who were far superior to the same level of Citigroup troops and their various field air defenses. The starting point was not to rely on comrades flying in the sky, but to do it themselves. Solve all problems.
I never expected that there would be a rich battle to fight.
They are targeting more than just the P-2V.
After everyone had expressed their opinions, the leader of the Defense Working Committee began to play the role of chairing the meeting: "Comrades, everyone understands the situation. Comrades of the expert group, let's discuss whether we agree to imitate air-to-air infrared combat. It’s about to enter the finalization process.”
The experts here all raised their hands, you’re kidding, if this can’t be finalized, what else can be finalized?
Including Gao Zhendong, although he knows better, but it depends on what era this is, this thing is guaranteed to crush his opponents.
Only the model chief engineer of the Institute of Guidance and Research felt less interested: "Thank you everyone for your affirmation and support of our work. However, this missile does not have forward attack capabilities and is severely affected by the sun. It is really a pity."< br>
Inwardly speaking, he actually felt that these things were all imitations, and anything that surpassed others was not done by him, or was not original to this hospital, and he always felt that it was not so perfect.
But others don’t know, why, you still don’t think it’s enough, comrade, you are getting a little advantage by being good.
It's so much better than Lao Maozi's, and you still feel sorry for it. That's a bit too much.
No one else could explain why, only Gao Zhendong smiled.
He knew what was wrong with this thing. In addition to the sensor, there was also the working principle of the seeker.
The sensor only determines one part, and the working principle of seeker detection and guidance is another part.
If you don’t change the sensor, but just change the working principle, you may not be able to attack forward, but if you improve the tail pursuit and anti-interference capabilities, it will not be a big problem.
As for why he knew? This involves not only chatting with each other in his previous life, but also the graduate school he wanted to take. He must first understand the school and major he wanted to take.
Hearing Gao Zhendong chuckle, everyone in the first row looked towards him.
The people from the Institute of Guidance and Research moved their heads very quickly, with surprise on their faces.
But the leaders of the National Defense Work Committee and the chief engineer have alarm bells ringing in their heads, huh?
Gao Zhendong continued: "This problem, maybe."
As soon as he said this, the leader of the National Defense Working Committee knew what he was going to say next, which was probably "It is not impossible to solve. ” and other words that are not difficult to understand at all, plus some technical suggestions that may be difficult to understand, and then the venue will be filled with a happy atmosphere. The only problem is
——This matter cannot be done like this in front of Many people said it!
The leader of the National Defense Working Committee shouted: "Stop talking!"
This sound shocked everyone. What mistake did this comrade make that he was not even allowed to speak? Just laughed a few times.
Except for a few people, they were overjoyed. Good stuff is coming. It seems that they will have to have a small meeting with Consultant Gao soon.
After the leader finished shouting, he slowly added: "Comrade Zhendong, let's talk about other things when we come down. Let's talk about the finalized things first."
Isn't it all decided? What else is there to say? ? However, Gao Zhendong also realized that there were probably too many people, so he couldn't tell, so he shut up.
The leader breathed a sigh of relief. As expected, this guy was just like what the chief engineer said. He was full of ideas and couldn't keep them at bay. Problems would arise if he wasn't careful.
But he was also itching in his heart. Is there any way Gao Zhendong can further improve the performance of the seeker? When Gao Zhendong opened this hole, some people who knew the root of the matter felt so itchy that they couldn't help it.
In this context, everyone quickly passed the final resolution of the meeting.
——The imitation infrared combat missile was named Thunder-1 and entered the formal finalization process. At the same time, there is no need to wait for finalization. The Institute of Guidance and Research has provided three complete sets of combat systems and a certain number of trial bombs to a modification factory in the Air Force for early trial use.
After the meeting, the comrades of the Institute of Guidance and Research immediately fixed their eyes on Gao Zhendong. Before Gao Zhendong stood up, the chief engineer of the National Defense Working Committee smiled and said: "Comrade Gao Zhendong, and the director Comrades from the Institute, stay here for a moment, there are other things to discuss.”
Gao Zhendong entered the next meeting without even moving his buttocks. This meeting originally didn't exist and was created by himself.
After everyone who needed to clear the place was cleared, only the leaders of the National Defense Working Committee, the chief engineer, comrades from the Institute of Guidance and Research, and Gao Zhendong were left.
The leader of the National Defense Work Committee smiled and said: "Okay, Zhendong, what you wanted to say just now can be said now. I am also very curious about what you want to say."
Research Guide The comrades in the hospital also looked at him eagerly. Gao Zhendong really wanted to say "forgot", but this was too much of a joke.
He nodded: "What I just wanted to say is that it's not impossible to solve, it just takes a little time, and the cost of missiles will increase."
That's true! Everyone had a feeling that it was as expected.
"Consultant Gao, what solution do you have, please give me some guidance."
The leader also nodded happily: "Well, let's talk first, let's talk first, let's ignore the cost."< br>
Gao Zhendong is not thinking about putting line scanning thermal imaging on missiles now. Let’s not talk about the things that have not been done yet, but the price of that thing is not ordinary expensive, and it can be put on a tank like a tank. It's acceptable for reused equipment, but it's a bit too wasteful to put it on missiles.
But he had an alternative.
He nodded: "Okay, if I remember correctly, I have seen the seeker materials provided by the Guidance Research Institute. Do you use an AM modulation disk for guidance?"
This involves the working principle of the seeker.
Many people are not aware of a problem. For early seekers, the infrared sensitive element is a whole piece. No matter where the infrared ray shines on its surface, it is sensitive to the Outputs a signal related to 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 has to mention the working principle of point source seekers. There are many types, but Gao Zhendong knows that AIM-9B, K-13, and Thunderbolt-2 all use the same type - amplitude modulation modulation disk guide. Lead.
The specifics are more complicated. A simple analogy is that this method adds a light-shielding disk - a modulation disk - in front of the infrared sensitive element. There is one or more channels of light transmission from the center of the circle outward. area, this light-shielding disk will rotate. When the light-transmitting area moves to the area where the infrared signal is located, the infrared signal will be projected through it onto the infrared photosensitive element.
In this case, based on the rotation position of the modulation disk, the location of the point source signal can be known.
This method is very clever. It converts the direction of detecting the target 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 target is solved. The problem of determining the orientation.
It sounds simple, but in fact it is more complicated.
After listening to Gao Zhendong's question, Lu Gong from the Guidance and Research Institute nodded: "Yes, AM modulation plate."
He is in charge of the guidance system and is also the leader of Lin Lianwei.
Gao Zhendong said: "The AM modulation dial will naturally block at least 50% of the signal, which is extremely detrimental to the detection sensitivity. And this mode has a huge flaw, that is When the infrared light source point 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 not good, and the signal It was cut in half at least, and the more accurate the alignment, the worse the signal. When was it aligned? When there is no signal.
Hey, there is no signal even if the lock is unlocked!
This seems very darkly humorous, but it's the truth.
Lu Gong nodded with some embarrassment: "There is this problem, but we haven't thought of a solution yet."
Not to mention now, Gao Zhendong's previous life was not until the 1980s. After improvement, the day lily is completely cool.
A seemingly simple principle. Anyway, we haven’t improved it for decades. It’s a fantasy, but this is reality.
Fortunately, Gao Zhendong knows the principle, and there are more than one.
But he decided to skip the middle ones that he knew were problematic and jump directly to one of the ultimate solutions before the advent of infrared focal plane arrays.
Gao Zhendong had to put in a pen at this time, otherwise he would not be able to explain where the next thing came from.
“When I saw the guidance principle used by comrades from the Guidance Research Institute, I realized that this principle made things worse for the already stretched infrared detection capability, so after work, I also We are considering how to solve this problem.”
Everyone was in awe, including the people from the National Defense Work Committee.
Comrade Gao Zhendong’s spirit is so selfless. You must know that the work of the Guidance and Research Institute is not his own job, and it is not even a serious job. How busy he is with his own work, no need to look at others , just look at the results.
Even under such circumstances, he did not forget to take time to devote himself to the guidance of air-to-air missiles.
The leader of the National Defense Working Committee didn’t know what to say: “Zhendong, you are here”
Tell him not to work or to work less? It’s unrealistic and reluctant to give up.
Gao Zhendong smiled and said something that shocked everyone.
“I considered three or four principles, and finally felt that orthogonal four-element detection is the most suitable.”
