Chapter 303 Technical bottlenecks
Self-guided offset is itself solidified in the seeker hardware.
The offset program of the missile homing head plays an important role in the safety control of the missile as a module that must be integrated by the manufacturing enterprises of all competitive missiles or competitive homing heads. To put it simply, when the missile is about to meet the target, no matter what type of target, the distance sensor on the missile will be triggered, and then the protection program will be activated and the avoidance route will enter the track automatically deflected.
That is to say, even if someone gets the air-to-air missile for competition and adds the warhead himself, he will waste all his strength to crack and shield the fire control and deflection module, and at the last moment, the seeker will also give false target information to drive the missile off target, so as to ensure the safety of the aircraft.
Of course, having said all this, the problem now is: the IFU rules and the "Regulations on the Monitoring of Missiles and Guidance Modules" do not allow any organization or individual to disassemble the missile and seeker modules for competitive use without permission; Otherwise, they will be punished as violations, and those who are strict may have to enter the class room.
Thinking of the rigid provisions of the "Monitoring Regulations", Long Yun was naturally speechless, so what should he do?
I don't know if it was influenced by Long Yun's thoughts, Liu Wei saw the captain's face embarrassed, but proposed a solution: "Brother Long, if you really want to see it, we can take the missile to the testing center." Although it costs a little bit of testing, it's always good to be safe, after all, we haven't sampled this batch of missiles since we received them? β
"Really?" Not long enough to stay in the aviation training center, Long Yun didn't know that there was such a department in the training base, "Okay, let's take a look at the internal structure, let's go!" β
β¦β¦
At the electronic equipment testing center of the aviation training base, after filling out a form and making notes on the Internet, Long Yun and Liu Wei were allowed to disassemble and test the missiles in the actual room of the testing center.
Unlike the missiles used by the army in the early days, there was no difficulty in disassembling the competition missiles, and after fiddling with special tools according to the instructions, the two quickly dismantled the milky white PL-12 missiles sent by the battery car and placed on the test bench into several compartments.
Sure enough, after disassembling the various modules of the missile, Long Yun probably knew at a glance that this was definitely not the original form of the PL-12 missile when it was in normal service.
Not to mention anything else, as far as the seeker in the fairing in the front of the PL-12 missile body is concerned, although Long Yun has not seen the real thing before, he has seen the pictures on the Internet: the narrow cylindrical module is stuffed with devices, and there is a small flat slit array antenna with a diameter close to the diameter of the missile in the front, Long Yun is still quite familiar with the missile guidance module.
But now, what is presented in front of the two of them is just a cylindrical assembly with a fairly high package, and the part in front that is protected by transparent material and has a little reflection seems to be the antenna, which looks like a small antenna array with AESA technology; Although the pillar behind it was not unloaded, with Long Yun's arm strength to pick it up and weigh it, the guidance module with a diameter of 200 millimeters and a length of more than 300 millimeters could be lifted by him lightly, so you can imagine how streamlined the components inside would be.
Realizing that there must be a famous hall in it, Long Yun suddenly became extremely curious about it, and he planned to disassemble it further, but he couldn't find a place to start. Probably it's encapsulated as a whole, and it doesn't need or allow the user to open it, right? And as Liu Wei said, Long Yun estimated that it was also equipped with an identification chip and a sensor to prevent disassembly, in order to monitor the whereabouts of the seeker. In this case, it is better not to do it lightly, Long Yun asked Liu Wei to put the guidance module on the ultrasonic detector in the corner of the real room, and try to start the ultrasonic detection equipment.
The guidance module with metal shell cannot see through the structure with ordinary electromagnetic wave perspective, but it is possible with an ultrasonic detector.
After adjusting the resonant frequency and the position of the probe, and scanning it like a CT scan for a patient, Long Yun leaned in and carefully looked at the three-dimensional structure schematic diagram displayed on the screen. Liu Wei on the side also felt very curious, and with his research on electronic devices, he could also see that the structure in the module was extremely simple:
"Sure enough, Brother Long, look, inside is a motherboard, plus a power supply module; There are very few chips and components, and the largest one should be a military-grade DSP (digital signal processing) chip, with a peripheral ROM (read-only memory) and a few small discrete devices. ββOh, and the antenna feed module that is integrated with the power supply, but nothing else. β
"Oh, it really is; It is estimated that the program is written directly in the programmable DSP, which is a signal processor. β
"No, of course the cost is low. In other words, it's useless for us to take it apart, there's just a little stuff in it, and there's nothing to study; If you want to change the guide program, you can't put it in if you don't have a burner. β
Seeing the perspective results on the screen, those few and clearly highly integrated components, Long Yun was a little deflated.
Not to mention the Soviet Union in 1996, even the United States, which had the world's highest level of electronic science and technology at that time, could not have imagined that such a missile could be imitated.
The Soviet Union's electronic technology has always been the shortcoming of its weapon system, not to mention, the beautiful line shape of the Su-27 is because of the almost one-ton huge N001 radar system has become so large, with two AL-31F with almost anti-sky thrust at that time, it can be pushed, and then there is still a certain gap between vertical maneuverability and F-15. As for missiles, judging from Long Yun's previous combat experience, the R-27 and R-73, which have been in production for more than ten years, have broken down from time to time, and as for the advanced missiles in front of them, I am afraid that they should not even think about it.
With the previous communication with Major Andrei of the "pennant", Long Yun did not want to look at the electronics industry department of the Soviet Union, he was thinking that if it was the original R-77, it was estimated that it could still be put into production in small batches for trial; But with such an integrated product in front of you, there is definitely no hope.
But if you think about it, you know that the R-77 on the market now must be a similar streamlined structure, as for the original R-77, it is estimated that in addition to the arsenal of the Soviet Russian Air Force to store expired ammunition, it is impossible to find it anywhere else.
ββIt's really tangled, how can this be good?
Do you want to give up? Active radar-guided missiles, that is a weapon for air combat that can be ignored after launch, Long Yun is of course extremely eager to use it. No, we have to think again!
Although the internal structure can be clearly observed from the screen, these parts and assemblies that are mediocre under the current level of science and technology are completely rare in the past.
In school before, Long Yun studied mechanical and electrical engineering, and he was still familiar with the electronic equipment and related modules on missiles; However, it can be said that it is completely impossible to consider how to reproduce the usable finished product with the actual missiles on the test bench as they are, and that it must be based on the technological level of the Soviet Union in the nineties of the last century.
Long Yun knows very clearly that the electronics industry is not an isolated technical field, it can be said to be a microcosm of the modern industrial system: every seemingly simple component needs the support of the entire industry and even the relevant industrial foundation across industries. The early days of large, complete industry and one factory are long gone, and almost all the finished products produced today can be traced back to countless industry sectors and product lines.
Take the most important antenna module as an example, which is completely different from the original R-77, the commercially available over-the-horizon missiles use AESA antennas, which can be made quite small in size and very inexpensive, and at the same time have more reliability and durability than the original R-77; However, it is such a small piece of antenna module that does not look good, but it needs to start from the basic SiO2 purification, and go down the process until it finally meets the requirements and can be assembled into a finished module.
The twists and turns of the production process in the middle, I am afraid that if you want to write, you can open a single book; However, Long Yun knew that except for professional and technical personnel, no one had the patience to look at such boring things.
And think about it from another angle, what was the level of electronic technology in the Soviet Union in the nineties of the last century?
Long Yun did not specialize in research, but even from the Su-27S that he recently took over, it can be seen: if nothing else, the disc mechanical instrument of that cabin alone, if it is not for conscious perception, will make him dizzy. Open the radome in the hangar, inside the huge N-001 radar, the diameter of the inverted Cassegrain antenna is 960 mm, but the typical search distance for heavy fighter targets (such as F-15) is only about 110 kilometers; Although it has been greatly improved compared to the single-pulse "artifact" with vacuum tube on the early MiG-25, the performance and reliability are indeed unsatisfactory - if it is not for constant temperature and humidity and frequent maintenance, it is common to drop the chain at a critical moment.
Regarding the shortcomings of the Soviet Union's electronic technology, Long Yun had suffered such a loss before, and of course he was very impressed. He sometimes wondered how many elements of the R-27 missiles that the enemy planes had successfully evaded when using the MiG-29 had such a poor record?
According to his pessimistic estimates, I am afraid that most of this is due to the drift error and cumulative error of the seeker or radar: with the killing radius of the R-27's warhead, as long as the deviation of the guidance calculation exceeds 10 meters, the enemy aircraft will basically be unharmed, not to mention those missiles whose seeker has failed and whose whereabouts are not known at all.
In short, after thinking about it for a long time, Long Yun came to the conclusion that the high-tech missile in front of him was by no means capable of being manufactured at the electronic level of the Soviet Union at that time.
If this road doesn't work, is there any other way?
