Chapter 153: Beheaded Warhead (4k)
It should be that they want to use a radar altimeter to replace the bellows barometer. The principle is figured out, but the DJS-59 is too big, just for a height problem. If something big goes in, the gain outweighs the gain.
But it’s still the same old rule, you can’t make it clear.
“Oh~~~That’s it~~~”
Hearing Gao Zhendong’s reaction, Lin Lianwei’s eyes lit up, here it comes again, here it comes again, the familiar feeling of talking to Zhendong came back again Coming.
Sure enough, what Gao Zhendong said next was exactly the same as before: "If you just want to obtain distance through electromagnetic waves, you don't necessarily need a device as big as DJS-59."
Hearing these words, the two people next to him became excited. Zhen, especially Su Weihua and Lin Lianwei were assigned by the Guidance and Research Institute to assist him, and he is the real owner.
He considered his words and spoke cautiously: "Well, Zhendong, if it doesn't involve your secrets, can you?"
If it were Lin Lianwei, he would definitely wait for Gao Zhendong calmly. spoke.
Gao Zhendong smiled and said: "It's just a basic principle, there is no secret at all."
"You can emit a continuous frequency-modulated wave modulated by a triangular wave from a moving object to the target, and mix the received reflected wave with the transmitted wave coupled from the transmitter. The difference frequency between the two outputs is related to the distance."
< br>“Use a frequency counter to measure the difference frequency, and you can get the distance with a simple conversion. This conversion does not require a computer. This method works in a continuous wave mode, using two antennas, one transmitting and one receiving.”< br>
“The frequency counter is much simpler than the DJS-59, haha. However, this method also has flaws. First, the accuracy will not be too high. Second, it must either ensure the directivity of the main lobe of the electromagnetic wave to the target, or The target has a large enough continuous surface. "
The last sentence actually makes it very clear what has a large enough continuous surface, such as the sea and the earth.
This is actually an FM radio altimeter. The advantage is that the structure is simple and the technical difficulty is low. The disadvantage is that the accuracy is average. But at this time, it is enough for anti-ship missiles at non-sea-skimming flight altitudes. Well done. A little bit, sea-skimming flight is not impossible.
When Su Weihua heard this, he suddenly became enlightened and patted himself on the head: "This method is good, the volume and weight are not large, the principle is simple, clear and feasible. When I got the new technology, I threw away the most basic principles. ”
Technology for the sake of technology, Gao Zhendong saw this a lot on the Internet in his previous life.
"It seems that the foundation is still not solid enough, so I need to learn more. Zhendong, I'd like to toast you. Not only did you help me solve a big problem this time, but you also taught me a lesson."
Gao Zhendong is not modest either. He touches a cup with him and solves a problem for you in advance that has not been solved for several years. It's not a loss if you toast him with a glass of wine.
I turned around and saw Lin Lianwei scratching his head and head. Did this comrade think of something of his own problem?
Lin Lianwei, who had been hesitating for a long time, suddenly remembered something. Isn't Gao Zhendong the technical consultant of our hospital? That's okay, you can ask.
He can't speak out for others about Su Weihua's project, but his own project is not a big problem, and he is asking questions, not passing things on.
Lin Lianwei suddenly felt that the world was widening, and said happily: "Zhendong, I have been transferred to support the people behind me recently. I have a small problem. You are responsible for the materials. See if you can solve it. Come up with an idea."
As soon as Su Weihua said this, he went to the toilet. Lin Lianwei was involved in his affairs. He could be listening, but he was not involved in Lin Lianwei's affairs. He understood everything. .
"What's behind you? Lian Wei, it seems you are walking ahead of the others? Haha."
Lin Lianwei smiled and said: "Why are you ahead of others? I used to work on the seeker. After you helped us solve the seeker cooling problem, I was transferred to support the warhead behind the seeker. ."
Fuck, it turned out to be such a behind-the-scenes person, Gao Zhendong cursed in his heart.
"Let me put it bluntly, the power of the warhead is a bit small, the fragments are a bit small, and the lethality is not enough."
"Increase the size of the fragments, there will be fewer fragments, increase the fragments As for the weight, the total weight of the warhead exceeds the limit. Use lightweight materials. It can't store energy. In short, it's just a dojo inside the screw shell. If it bumps here or there, it can still be used, but it can be used against it. Bigger airplanes always feel less interesting. You are a material man, do you have any ideas?”
Gao Zhendong didn’t have to think about it, the answer was already there. Netizens talked about it when he visited the military website in his previous life. Head warhead: "Well, you don't have to look for material problems, you can solve them with structural problems."
"Structure? There is only so much space, how can I make it."
"Come on, let me draw one for you." Gao Zhendong took out a pen and paper and drew a schematic diagram of a continuous rod warhead for Lin Lianwei .
The continuous rod warhead is a warhead form that will be widely used in air-to-air missiles in the future. Simply put, many long rods are connected end to end to form a ring shape, and then folded into a cylinder and placed into the outer circumference of the warhead.
When the warhead takes effect, it will explode the ring and spread it around in a circular shape. If it explodes on the head of an enemy plane, it may even cut off the nose of the plane directly.
When Lin Lianwei heard this, he almost jumped up. It was not that he had never seen the world before, but Gao Zhendong's reaction was too fast, and the plan he proposed was simply tailor-made for his air-to-air missiles. .
He said hello to the back: "Lao Su, you can come out now."
Then, regardless of his small capacity for drinking, he picked up the cup and said: "No more words, Lao Gao, I respect you!"
The three of them chatted and laughed after the meal, and Gao Zhendong left most of the remaining bottle of wine to Lin Lianwei.
The two sent Gao Zhendong away, ignoring the smell of alcohol. They looked at each other and went straight to the office.
I couldn't hold myself back for a long time, but if I just left Gao Zhendong and ran to the office, it seemed a bit unreasonable to throw the matchmaker against the wall when a newcomer came into the room.
The two rushed into the office, where Su Weihua's leaders Qi Gong and Lu Gong were still discussing the radar altimeter plan.
Seeing the two of them, Lu Gong frowned: "Xiao Lin, didn't you go to a party with Director Gao's old classmates? After drinking, go home and rest."
Lin Lianwei said in high spirits: "Have a rest. No rest, Gong Lu, guess what good stuff we got from Gao Zhendong just now?"
Gong Lu immediately looked happy: "Oh? What's the good news?"
< br>This scene is like a future salesman who is late for work and smells of alcohol. The sales manager blames him, but he says, "I drank with Party A until 3 o'clock in the morning last night. Guess how big an order I signed?" Same.
Since Lin Lianwei dared to say so confidently that he got something good from Gao Zhendong, with Gao Zhendong's ability and style, he couldn't be wrong.
Lin Lianwei and Su Weihua reported Gao Zhendong’s solution to the two leaders. They were overjoyed. Lu Gong smiled and said: “It is indeed Director Gao’s style, simple, convenient, low cost, and based on the most basic principles. Go straight to the core of the problem, wonderful!”
Gong Qi also said with a smile: “No show of skills, no pretentiousness, no craftsmanship, this Director Gao is awesome!”
Hearing this, Gong Lu said, Qi Gong smiled and said: "If he shows off his skills, it will be another scene."
After speaking, in the curious eyes of the other party, he raised his chin and pointed at DJS-59: "This thing , he also researched it alone, how does this technology show off?”
Qi Gong was immediately shocked: "A single person? I can't imagine it, I can't imagine it."
After admiring for a long time, Qi Gong remembered a worry: "But will there be problems with confidentiality procedures?"
Gong Lu shook his head: "Don't worry, I guess the two of them didn't even say what they were doing."
Facts have proved that Jiang is still hot when he is not on the scene. Guess how they communicate.
Lin and Su roughly said the exact words communicated between the three of them. Qi Gong felt relieved and didn't really say anything. Lu Gong smiled and said, "Actually, you don't have to worry too much. Director Gao is our unit's special technical consultant. With Lian Wei here, the procedures are reasonable. And I estimate that his confidentiality level should be higher than the two of us."
Qi Gong was stunned: "Aren't they two classmates? The administrative level is so high?"
"The administrative level is not high, just a deputy subject, but the confidentiality level should not be low."
Hearing this, Lin Lianwei interjected: "Deputy department, level 7 engineer."
Lu Gong: "Huh?!" This time, the administrative level is not lower than his own.
After thinking about it, it seemed normal. I stopped talking about this and greeted everyone: "We will follow this plan. Director Gao can't give us all the answers. We even have to ask others to make frequency meters."< br>
Everyone responded enthusiastically and rushed to their jobs.
Only Lin Lianwei turned around and was about to leave the office.
Gong Lu stopped him: "What are you doing?"
Lin Lianwei turned his head: "Gong Lu, aren't I at the war department now? I was at Lao Gao's just now. When I get something, I have to hurry over.”
Lu Gong: "Does he even understand this? Go ahead, go ahead."
Qi Gong was thoughtful when he heard this.
When the people in the war department heard Gao Zhendong’s ideas relayed by Lin Lianwei, they all felt that there was something wrong. What were they still doing? Let’s go to the test!
In just half the night, they built an experimental warhead.
There is no shortage of metal strips in the courtyard. For the problem of connecting end to end, just tie them with electrical tape, but it is not used too much. It is experimental anyway. Just verify the principle. Remove the original battle Just use the prefabricated fragment sleeve at the bottom and put it on the continuous rod sleeve.
Install the test warhead on the test bench and surround it with target cloth at a certain distance.
Everyone who worked on the infrared air-to-air combat bomb project of the Guangdong Research Institute came here as long as they were in the hospital. They are really fierce, they just have to face the thunder and fire, commonly known as watching the fun.
With the order, the test warhead exploded.
When the smoke cleared, everyone gathered around.
“Hey, it’s really good. Although the processing of the continuous rod sleeve is very crude, it can be seen that it flies roughly as expected.”
"Well, this is to concentrate the limited fragments on a circular surface around the warhead."
"In this way, the strike area can basically be predicted."
"It's a bit mechanical. The version of the shaped energy warhead is interesting, haha."
"I think all air-to-air missiles can use this thing."
"If the timing of this is good. , you can beheaded directly.”
"."
——
The next day after he helped a classmate who was working on missiles with two small favors, Gao Zhendong said hello to Lao Chen and then went directly to the machine in the factory. I have to go through the channel to send the report of the single crystal furnace to the 17th Machinery Department.
But he himself was thinking about another thing.
Yesterday's conversation with Su Weihua and the others reminded him of something worth doing, and this thing is not addition or research on new things, but subtraction, and the speed of doing it should not be too slow.
The monocrystalline furnace must be a collective one, and he can sit in the middle and take charge. Then he can spare a lot of time to do this.
Safe production and tank gun stability are almost finished. The remaining things, such as "Automatic Control Principles", are long-term matters.
It’s boring to just focus on the operating system every day. You still need to diversify your development and change your mind frequently.
Just do it, Gao Zhendong took out the paper and started making plans.
This plan is for myself, not for reporting. I can just do this quietly and then bring it out.
"Ding ding, ding, ding, ding."
The phone on the desk rang, and the purely mechanical ringing tone was very crisp, even a little harsh.
Gao Zhendong, who was not used to having a phone, was startled and picked up the phone.
"Director Gao, this is the factory office. We have received a notice from the ministry to inform you to attend the 17th Ministry of Machinery's 'Fire Technology Award' award ceremony held at 9 a.m. on Friday."
Hang up the phone, Gao Zhendong was a little curious, "Fire Technology Award"? Never heard of it in my previous life.
Even the National Science and Technology Progress Award was only established in 1984.
However, regarding such details, Gao Zhendong asked himself that he was an ordinary college student in his previous life and was unclear about many things. Maybe it already exists, but I just don’t know it.
"Fire", when you hear it, it has the flavor of the 17th Ministry of Machinery in it. It is like the "Luban Award" and "Dayu Award" that you will hear in the future. When you hear it, you will probably know which one it is. Ministerial Award from the Ministry.
What Gao Zhendong didn’t know was that this award was fanned out by his own little butterfly wings. Naturally, he had never heard of it in his previous life.
A prize will be given out, and participants will be notified specifically. According to the rules, I should be on the list, but I don’t know which level it is and how many.
After counting his achievements, Gao Zhendong felt that not all of them should be distributed according to the actual meaning of the results, which would be a bit too much.
What Gao Zhendong didn't know was that at this time, in addition to himself, many people involved in his various projects had been notified. These people included the Third Steel Rolling Plant and the Capital Steel Plant.
Those like Mr. Chen, Liang Fafa, Fang Yinghong, and Liu Rongguo are all scattered in various projects.
As for Factory Director Yang and Deputy Factory Director Li, they don’t have it. They follow the administrative line and can take care of their affairs by taking the collective honor of the project.
It seems that the Ministry's idea is that the technical award is a technical award, and administrative management is not left behind. It is resolved with collective honors, but individual awards are specially awarded to technical personnel.
Of course, whoever is the technical staff is actually relatively flexible, so that goes a long way.
But at least the starting point is very clear.
