Chapter 574 Palm Technique Falling from the Sky
Gao Zhendong knew that the attraction of this thing to them was absolutely huge, and there would be no second result. He nodded and smiled: "Okay, I will tell you. Talk about this laser-guided bomb component."
Component? Before getting into the details, the comrades at Chunlei Factory felt like they had been hit in the face. What was this concept?
This is why Gao Zhendong said that there is actually no difference between 250kg and 500kg. They are both the same thing. He wants to make a guidance component that can be put on the bomb head!
As for gliding guidance, it is not necessary for the time being. If the distance is far, the laser receiver cannot receive the signal, and other means must be used to determine the initial launch direction and distance, which complicates the system. This capability exceeds the current enemy's air defense firepower capabilities. It is not necessary but the cost is huge.
Until the 21st century, laser-guided bombs with gliding components were extremely rare, and not without reason.
“Ah, yes, components.”
Having someone put his idea into practice made Gao Zhendong feel very good. He said cheerfully: “This thing is used to put it on the present On the bomb head, there is no need to produce new bombs. "
The free-fall bombs we use are all high-resistance bombs with resistance rings. This is to make the bombs fly more stably and improve their hit rate. The efficiency is high, but it doesn't work well when used on guided bombs.
The comrades at Chunlei Factory suddenly realized that this method is good, the cost is much lower, and as long as sufficient preliminary research is done, any bomb can be put on it and turned into a guided bomb.
Low cost and abundant ammunition sources.
Just thinking about this little bit, I can’t accept it. The technology is really applied, plus the actual situation, nothing is left behind.
"Would that destroy the flight attitude of the bomb?" asked the engineer in charge of the guidance system at Chunlei Factory, the same engineer who was tortured to death by the disconnection problem.
"No, this bomb is meant to move around and does not need a too stable attitude. As for basic stability, the complex tail structure can provide guarantee, that's it, in the guidance assembly Xanadu also needs to use large control wings to solve the problem of over-stability of the missile body and insufficient control torque.”
The high-resistance bomb we use is of the same lineage as Lao Maozi. It not only has a tail fin, but also a tail fin. The ring-shaped tail is stable, but it is not easy to move even if you want to.
This is a bit like the difference between high static stability and relaxed static stability of an airplane. If the stability is high, the agility will be bad. For example, the flying tractor is very stable.
After hearing this, Zhou Gong realized that he was desperate for a sword. This thing actively guarantees the hit rate, which is completely different from the high-resistance bomb that requires everything to be stable.
But this also means one thing. This thing is basically his job alone, and the others are not very useful.
There is no power, and it has little to do with the power system chief engineer.
Without changing the projectile body much, aerodynamics mainly solves the problems of the falling process and the control process.
As for the charge, if the charge needs to be changed, why would Chief Engineer Gao bother with the components? Wouldn’t it be enough to just produce new ones?
Hey, I never thought I could eat alone!
Zhou Gong immediately threw the failure of SS.11 out of his mind.
"Mr. Gao, tell me, what are the overall requirements for this guidance component?"
Gao Zhendong smiled: "In fact, there are not many. The first one is to lower the bomb. Flight resistance, so that it can at least glide forward as much as possible and increase its range.”
Zhou Gong repeatedly told himself in his head that this was a guided bomb and the requirements were different, so don't forget it.
"Can we add an engine to make the bomb have a greater range?" The comrades who worked on the power were still a little unwilling. This thing was of no use to them.
Gao Zhendong shook his head: "The laser guidance range is limited, and there is no point in increasing the range. Moreover, it becomes a missile if it is used over and over again. It is too complicated and the cost goes up. It deviates from the original intention and exceeds the goal. What is needed now. A bomb is a bomb. Even if you want to increase the range, there are some other methods, but laser guidance is not very useful. The low-resistance sliding distance is enough."
Gao Zhendong thought for a while. , but added that it has nothing to do with technology, but it is also very important in his opinion: "My personal habit is to keep in mind an iron rule when doing engineering application research - don't be greedy. You need this and that, and you will find out in the end It deviates far from the original intention and loses its practical significance.”
He just said that it is a personal habit. As for whether others can listen to it or not, he has no control over it and does not want to care about it.
After hearing his words, the eyes of several comrades flashed, and someone thoughtfully wrote these three words in his notebook and circled them heavily.
Seeing this situation, no matter whether they were pretending or not, at least they remembered it, and Gao Zhendong was also a little happy.
He talked about the second requirement: "The shell of this component must have a certain thickness, hardness, and a sharper shape, so that it can provide a certain ability to penetrate into the ground. This thing is used for It is used to attack the enemy's hard targets. "Specialized ground-penetrating bombs are not needed for the time being. Guidance components can be used to provide certain ground-penetrating capabilities, which can take into account some situations. Moreover, the original requirement of low resistance requires that the shape of the components is sharp and smooth enough. Line, follow the trend and kill two birds with one stone.
Hey, this idea is simple but brilliant, Zhou Gong happily wrote it down.
"Third, this component must have the ability to be directly installed on existing commonly used 250kg and 500kg high-resistance bombs through accessories without modifying the missile body. At the same time, it must have a certain power supply capability, as the bomb itself has no power."< br>
“Ah, these are easy to solve. We know the structure of the bomb best. Universal installation components are easy to handle. As for power generation, I will install a small turbine on the top of the component. As long as it has a certain speed, it can Generate electricity. So how is this laser guidance guided? "
It was easy for Chunlei Factory when Gao Zhendong put forward these two requirements. But they were still confused about the guidance system.
To be honest, Zhou Gongdu still only knows about lasers, but only has a partial understanding of them. He only knows that the energy density is high, the directionality and monochromaticity are good, but how to use it for guidance, he has no idea. Thought about it.
“Use laser semi-active guidance, use the laser to illuminate the target, and the receiver on the component receives the laser to control the direction. As for this irradiation laser, you have to consider two types, one is carried by ground infantry or vehicles, and the other is carried by ground infantry or vehicles. The two are hung on the plane, and these two are one of the most difficult things you have to do this time.”
Laser beam and laser active guidance have many restrictions and are not suitable for use on guided bombs.
The former has requirements for the spatial relationship between the target, illuminator, and bomb, while the latter greatly increases the complexity of the guidance component. Even in the 21st century, precision ammunition with laser active guidance is still not much.
Not to mention the attenuation problem in air, dust, and smoke, the advantage of good laser directionality turns into a disadvantage here. As for the active guidance method with higher technical requirements, it is not needed at this time. consider.
Moreover, the guidance component is not that big to provide enough power for the illuminator, so the guided bomb does not have active laser guidance.
Semi-active is different. It leaves the most troublesome task to the guidance pod or guidance system. The structure on the missile is extremely simple and the cost is low.
"Mr. Gao, I can understand the pod on the plane, but what is the use of this thing on the ground?"
"The guidance system of this thing is originally detachable. Think about it, if you are an infantryman, There is a big bunker ahead. Due to weather, cloud cover, observation angle, observation time, etc., the aircraft cannot provide illumination at low altitude in a hurry. For example, what should I do? For example, the targets in the mountains are often less illuminated by aircraft in the sky. It's difficult, but the Army doesn't have such restrictions."
Zhou Gong thought about it and became excited: "Call the air force to drop the bomb and provide illumination from the ground? The bomb fell from the sky and hit the target accurately. !”
“By the way, this is called a palm falling from the sky.”
“Mr. Gao, this is great, but where can we get a laser? We can’t even carry out the most basic research.”
This is where they are most troubled. They are not familiar with this thing. If they rub a laser by themselves, it will take years and years, and they may not be able to rub it out.
Unexpectedly, Gao Zhendong had already prepared it for them.
"I will give you a unit name later and write a note explaining the whole story. You take these two things to the National Defense Work Committee to ask for the procedures, and then go to them. This unit has lasers that you can use. , and they have certain application experience and rich experience in calculating laser emission power and receiving power, which is very useful to you.”
This unit is naturally the Grassland Tractor Factory, Mr. He. There, the 1064nm laser used in their laser rangefinder has a longer wavelength and better penetration, which is suitable for guidance.
The best one is undoubtedly the long-wave laser, which has stronger penetrating ability.
For example, the one about 10μm, but that thing is troublesome to make and takes time. It is also a good choice to use 1.06μm to make the laser-guided bomb first.
It’s a big difference if there is any difference.
Mr. Gao is quite nice. Even this matter was solved, and Zhou Gong looked happy. It can be said that with these things provided by Gao Zhendong, this laser-guided bomb is basically taking shape. At least it can produce something with a hit rate far exceeding that of a free-fall bomb.
Seeing that he had basically understood his idea, Gao Zhendong did not continue to delve into the technical details, but directly arranged the next step of his work.
"Mr. Zhang, Zhou Gong, I'm going to trouble you about the next thing. Make the project approval materials for this laser-guided bomb and report it to the National Defense Work Committee, Lu... No, this thing should be air They should be interested in it.”
When it comes to specific implementation, Gao Zhendong has always been a hands-off shopkeeper, wishing he could finish explaining the principles and routes by himself so that he would have nothing to do.
