Chapter 635: Machine bomb/munition network collaborative passive positioning
Faced with this somewhat sudden request, He Ming did not give a direct answer:
“Yes, yes, but Mr. Chang The project at hand is not directly related to us, so we have to report it to the higher authorities.”
“If it’s convenient, can you tell me why you want to find him...”
The question is only halfway through. Directly answered by Guo Liqiang:
"I just thought of a way to extend the effective attack range of this missile under the existing technical conditions, but it involves some problems at the system prediction algorithm level. I need to confirm with Mr. Chang."
Said this As he spoke, there was a sparkle in his eyes, and his tone of voice was much higher than when they were just chatting.
He Ming was keenly aware of the changes in the other party.
He knew that this was a sign of inspiration.
For "ordinary" researchers like them, this is an opportunity that only happens a few times in a lifetime.
Although the sudden flash of inspiration does not mean that you can directly come up with any results like a certain Mr. Chang who is not a human being, the relevant ideas formed in your mind are basically valuable.
So, this situation must still be reported to Chang Haonan.
There is no guarantee that some new results will be produced.
But what He Ming just said was not entirely an excuse.
Chang Haonan did not join Project 11, and he is not a member of the Taihang Project, so I really don’t know where the former is at the moment.
In short, it is neither in Shengjing nor in the capital.
For more details, you have to report to the Science and Technology Commission to apply for contact.
So, after a little thought, He Ming thought of a safer way:
"In this case, I will contact my superiors immediately and ask where Mr. Chang is currently and what is the fastest way? I can meet him when the time comes.”
“As for Mr. Guo, you can settle down in our factory for a few days and take advantage of this time to sort out the ideas you just had. It’s best to improve them so that you can share them with Mr. Chang. The communication efficiency after meeting is also better, how about it? ”
For Guo Liqiang, this was basically the best solution he could think of, so he nodded decisively:
"No problem, then why bother?"
After that After that, he turned back and looked at a young colleague who came with him:
"Xiao Fang, please find the department's internal phone number later and contact the hospital and tell me that I have It’s confirmed, please ask the leaders of the institute to organize a group of people with foreign liaison experience as soon as possible to prepare for negotiations with the Pennant Design Bureau.”
“As for the formal project feasibility report and project application, I will wait a little later. The sky is up.”
"Yes!"
The entourage named Xiao Fang replied simply.
……
He Ming’s application was quickly passed to the Commission of Science, Technology and Industry for National Defense.
In fact, in most cases, meeting Chang Haonan does not require any particularly complicated procedures.
Just make an appointment with Torch Group.
The problem is that he is currently conducting high-altitude test of Turbofan 10 at Institute 624——
Whether it is Institute 624, the Turbofan 10 project, or the facility SB101 high-altitude platform , all top secret.
Fortunately, although Guo Liqiang and Chang Haonan are not familiar with each other, or the entire aerospace science and technology system has not had any direct relationship with Chang Haonan yet, they are all units under the Science and Technology Commission system. .
So after Ding Gaoheng confirmed the situation with the Aerospace Science and Technology Group through the System Engineering Department in charge of the aerospace industry, he gave instructions——
Comrade Chang Haonan is performing a major project R&D and testing task and cannot leave within a short period of time. Considering that the actual situation requires it, Comrade Guo Liqiang is approved to go to Fucheng 624 Institute, but the itinerary needs to comply with the arrangements of the other party's agency.
Three days later, Guo Liqiang flew from Shengjing to Rongcheng with this instruction, the letter of introduction issued by Factory 112, and the relevant information he had summarized in the past few days.
As usual, a dedicated person from the 624 Station will be dispatched to pick you up.
Of course Chang Haonan had received news from Ding Gaoheng a long time ago and knew that Guo Liqiang, whom he had only met once, wanted to discuss something with him.
So a day of less important content was specially arranged on the test schedule.
When the tired Guo Liqiang was brought to a conference room in the 624th Institution Building, Chang Haonan was already waiting here.
"Mr. Chang, I have kept you waiting for a long time."
The moment he saw the latter, Guo Liqiang finally breathed a sigh of relief.
"Director Guo flew to Fucheng specifically to find me. He must have something very important. It doesn't hurt to wait for a while."
Chang Haonan stood up and shook hands with the other party. .
In the previous phone call, Ding Gaoheng did not go into too many details.
Of course he could guess that the purpose of Guo Liqiang's trip must be related to the ultra-long-range air-to-air bomb based on R33.
But I really can’t think of anything in it that deserves an interview with myself. After the distance got closer, Chang Haonan noticed that Guo Liqiang's face was a little pale:
"Do you need to have breakfast first?"
"No, we've already eaten on the plane, it's more important to talk about business."
Guo Liqiang waved his hand and put the briefcase he was carrying on the table:
"Also, Mr. Chang Just call me Guo Gong. Speaking of which, I owe my position as director to you. If I hadn’t been inspired by that paper, Thunderbolt 11 wouldn’t have been finalized so quickly.”
That’s it. While chatting, he didn't stop moving his hands and had already taken out several bound books from his bag.
The two of them found a seat at the conference table and sat down.
"Mr. Chang, I actually flew here directly from Shengjing. Vice President He Minghe of Factory 112 said that it was you who recommended him to give me the project of introducing domestically produced and improving ultra-long-range air-to-air bombs."
Chang Haonan nodded:
"Yes, because I have calculated that after you finish the Thunderbolt 11, you should not have too much burden, and you will be able to continue."
"So I came here with a brand new idea."
Guo Liqiang pushed a few piles of information in front of Chang Haonan:
"Generally speaking, anti-radiation missiles with passive radar guidance function, whether the target is in the air or on the ground, need to be cooperated with a dedicated electronic warfare aircraft to maximize their combat effectiveness."
"But The range of the R33 bomb is actually a bit too far. Before reaching the end, the search range of our country's existing fighter jet airborne radar is not enough, making it difficult to provide complete mid-course guidance, and the accuracy of passive radar guidance at mid-to-long distances is very poor. There is no way for the missile to accurately find the target based on electromagnetic wave tracing. "In this way, the missile will either not be able to take advantage of the ultra-long range and be forced to operate in the advantageous range of the medium-range missile. Or if it is forced out, it will easily break off in the middle and will not pose any effective threat to the enemy aircraft.”
“So I thought about whether I could use the huge size of the R33 platform and not make it simple. As a missile, but as part of the entire search system, the passive detection radar of the electronic warfare aircraft and the airborne long-range missile are networked to locate ultra-long-distance or low-detectability targets? "
At the beginning, Chang Haonan listened to Guo Liqiang's ideas with a relaxed and slightly curious attitude.
However, when he heard the last one, which was to let missiles and aircraft cooperate in coordinated searches, his expression instantly became serious and his brain began to work rapidly.
There is no doubt that Guo Liqiang’s idea is definitely many years ahead of this era.
Using multiple aircraft to coordinate, and using random agile multi-platform mutual guidance signals through a data link network to stagger the positioning of enemy radar systems, this was an idea in the 2010s, and many countries have conducted relevant research. There will be more than 3.
In the late 1990s, the data link network was considered a proper alien technology, and you didn’t need to think about it in the short term.
Not to mention China, not even the United States has a multi-directional high-capacity data link that can meet this requirement.
But the requirements can be completely lowered. Instead of random agility to multiple platforms, there will be coordination between missiles of fixed models or even fixed codes, or between missiles and carrier aircraft.
This only requires a non-universal one-way data transmission system, which directly reduces the difficulty by several dimensions.
By analogy, the former is equivalent to a true A-shooter and B-guider, such as using the F35 to guide the Standard 6, or the Su-35 to guide the 48N6 to hit over-the-horizon targets.
The key point is that neither A nor B needs to be specified in advance. As long as two gadgets that meet the requirements are fished out from the war zone, they can coordinate smoothly. Until the 2020s, only a few tests have been conducted under ideal conditions. Work hard.
But the latter is similar to when the Red Navy used relay helicopters to guide long-range anti-ship missiles to attack aircraft carriers. Although it sounds like A shooting and B guiding, the A and B here are both predetermined. , it won’t work if you replace one of them.
So it was a mature technology even in the 1970s.
Although tactical flexibility is a complete mess, it is better than nothing.
You must know that the J-Handian 7 he designed before has relatively complete passive detection capabilities.
If two more missiles with networking capabilities are mounted, it will be equivalent to having two more weaker aircraft of the same type in this airspace, which can greatly enhance the accuracy of capturing targets. .
More importantly, the missile is extremely fast and almost impossible to intercept, and it will continue to shorten the distance to the target as time goes by.
Of course, there is a cost.
Such a missile is designed almost according to aircraft standards, and the cost must be quite staggering.
Furthermore, the flight window of the missile is relatively short, no more than 5 minutes at most. After capturing the target, it is likely that it will be too late to turn around and launch an attack and will need to hit the target.
In other words, at least 3-4 missiles must be fired in one attack.
But it is really impossible for the JH-7 to carry more ammunition.
If you really want to realize the potential of this combat mode, you can either change to a flying platform with more hardpoints and a larger bomb load, such as the J-11.
Or just put the entire system on the ground and use it as an anti-aircraft weapon...
For Guo Liqiang, Chang Haonan's long silence was like waiting for trial.
But he didn’t dare to interrupt the other person’s thinking casually.
Finally, after more than ten long minutes, Chang Haonan finally raised his head and looked at Guo Liqiang who looked worried again:
"Your idea...should be feasible!"
