Chapter 574 The Palm Technique Falling from the Sky

Gao Zhendong knew that this thing was absolutely attractive to them, and there would be no other result. He nodded and smiled, "Okay, then, I'll tell you about this laser-guided bomb assembly."

Components? Before we even got into the details, the people at Chunlei Factory were shocked. What was this?
This is why Gao Zhendong said that there is actually no difference between 250kg and 500kg, they are the same thing. He wants to make a guidance component that can be put on the head of the bomb!

As for glide guidance, it is not necessary for the time being. The laser receiver cannot receive the signal at a long distance, and other means must be used to determine the initial launch direction and distance, which complicates the system. This capability exceeds the current enemy air defense firepower, so it is not necessary, but the cost is huge.

Laser-guided bombs with glide components were extremely rare until the 21st century, and for a reason.

"Ah yes, components."

Gao Zhendong was in a very good mood to have someone implement his ideas. He said cheerfully: "This thing is used to put on the head of the current bomb, so there is no need to specially produce new bombs."

The free-fall bombs we use are all high-drag bombs with drag rings. This is to make the bomb fly more stably and increase the hit rate a little, but it doesn't work well when used on guided bombs.

The comrades at the Chunlei Factory suddenly realized that this was a good idea. The cost was much lower, and as long as sufficient preliminary research was done, any bomb could be used and turned into a guided bomb.

The cost is low and the ammunition source is abundant.

Just considering this little bit, you can't help but admit it. They have really not fallen behind in both technology and application, as well as the actual situation.

"Will that destroy the bomb's flight posture?" asked Engineer Zhou, who was in charge of the guidance system at the Chunlei Factory. He was the engineer who was tortured to death by the broken wire problem.

"No, this missile is meant to move around, so it doesn't need a very stable attitude. The basic stability can be guaranteed by the complex tail structure. Even so, the guidance assembly still needs a large control wing to solve the problem of the missile body's overly stable flight and insufficient control torque."

The high-drag bombs we use are of the same generation as those used by the Russians. They not only have tail fins, but also circular tail fins. They are stable, but it is not easy to make them move.

This is a bit like the difference between an aircraft with high static stability and one with relaxed static stability. If the stability is high, the agility will not be very good. For example, the flying tractor is very stable.

Upon hearing this, Mr. Zhou realized that he was trying to find a sword by imitating the mark on the feet. This thing actively guarantees the hit rate, which is completely different from the high-drag bomb which requires stability.

But this also shows one thing, this thing is basically his job alone, and others are of little use.

Lack of power has little to do with the chief designer of the power system.

If the projectile is not significantly modified, the aerodynamics will mainly be used to solve the problems of the falling process and the control process.

As for the charge, if the charge needs to be replaced, why would Chief Engineer Gao bother with the components? Can't he just produce new ones?

Hehe, I didn’t expect that I could eat alone!
Mr. Zhou immediately forgot about the failure of SS.11.

"Mr. Gao, can you tell me what the overall requirements are for this guidance component?"

Gao Zhendong smiled and said, "Not much actually. First, we need to reduce the bomb's flight resistance so that it can at least glide forward as far as possible and increase its range."

Mr. Zhou kept telling himself in his head that this was a guided bomb with different requirements, so don't get it wrong.

"Can we add an engine to extend the range of the bomb?" The comrades who were in charge of the power were still a little unwilling, as this thing had nothing to do with them.

Gao Zhendong shook his head: "Laser guidance has a limited range, so there is no point in increasing the range. Besides, it will become a missile, which is too complicated and the cost is also high. It has deviated from the original intention and exceeds current needs. A bomb is a bomb. Even if the range needs to be increased, there are other means. However, laser guidance is not very useful. The distance of low-drag gliding is enough."

Gao Zhendong thought about it and added a sentence. It has nothing to do with technology, but in his opinion it is also very important: "My personal habit is to keep in mind an iron rule when doing engineering application research - don't be greedy. If you want this and that, you will find that you have deviated far from the original intention and lost the practical significance."

He just said it was a personal habit. As for whether others listened to him or not, or what kind of evaluation they made, he had no control over it, and didn't want to care.

Hearing his words, several comrades' eyes flashed, and someone thoughtfully wrote these three words on his notebook and circled them heavily.

Seeing this, no matter whether people were pretending or not, at least they remembered it, and Gao Zhendong felt somewhat happy.

He talked about the second requirement: "The shell of this component must have a certain thickness and hardness, and a sharp shape, so that it can provide a certain ground-penetrating capability. This thing is to be used to attack the enemy's hard targets." Specialized bunker-buster bombs are not needed for the time being, but the guidance components can be used to provide a certain ground-penetrating capability, which can take into account more situations. Moreover, the requirement of low resistance requires that the component's shape be sharp and streamlined enough, so it is a case of killing two birds with one stone.

Hey, this idea is simple but brilliant. Mr. Zhou happily wrote it down.

"Third, this component must be able to be directly installed on the existing commonly used 250kg and 500kg high-drag bombs through accessories without modifying the bomb body. At the same time, it must have a certain power supply capacity, because the bomb itself has no electricity."

"Ah, these are easy to solve. We know the structure of the bomb very well. The 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 reaches a certain speed, it can generate electricity. Then how does this laser guidance work specifically?"

Gao Zhendong's two requests made things easier for Chunlei Factory. However, they were still confused about the guidance system.

To be honest, when it comes to lasers, Mr. Zhou is still only somewhat aware of them. He only knows that they have high energy density, good directionality and monochromaticity, but he has never thought about how to use them for guidance.

"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 the illuminating laser, you have to consider two types, one is carried by ground infantry or vehicles, and the other is hung on the aircraft. These two are one of the key points you have to deal with this time."

Laser beam and laser active guidance have many restrictions and are not suitable for use on guided bombs.

The former requires the spatial relationship between the target, illuminator and missile, while the latter greatly increases the complexity of the guidance components. Even in the 21st century, there are not many precision ammunition using active laser guidance.

Not to mention the attenuation problem in air, dust and smoke, the advantage of laser directionality has become a disadvantage here. As for the active guidance method with higher technical requirements, there is no need to consider it at this time.

Moreover, the guidance component is not large enough to provide enough power to the illuminator, so the guided bomb does not have active laser guidance.

Semi-active missiles are different. The most troublesome tasks are left to the guidance pod or guidance system. The structure on the missile is extremely simple and the cost is low.

"Boss Gao, I can understand the pod on the plane, but what is the purpose of using this thing on the ground?"

"The guidance system of this thing can be separated. Think about it. If you are an infantryman and there is a large bunker in front of you, what should you do if the aircraft cannot provide low-altitude illumination in a hurry due to weather, cloud cover, observation angle, observation time, etc.? For example, it is often difficult for aircraft in the sky to illuminate targets in mountain nests, but the army does not have this limitation."

Engineer Zhou thought about what Gao Zhendong said and became excited: "Call the Air Force to drop the bombs and let the ground provide illumination? The bombs fell from the sky and hit the target accurately!"

"That's right, this is called a palm falling from the sky."

"Mr. Gao, this thing is good, but where can we get the laser? Without it, we can't even carry out the most basic research."

This is the most difficult part for them. They are not familiar with this thing. If they try to make a laser by themselves, it will take a long time, and they may not even be able to make it.

Unexpectedly, Gao Zhendong had already prepared for them.

"I'll give you a unit name and write a note explaining the whole story. You can take these two things to the Defense Work Committee to get the formalities, and then go to them. This unit has lasers that you can use, and they have certain application experience. They have rich experience in calculating the emission power and receiving power of lasers, which will be very useful to you."

This unit is naturally the Grassland Tractor Factory. Mr. He's laser rangefinder uses a 1064nm laser with a longer wavelength and better penetration, which is just right for guidance.

The best one is undoubtedly the long-wave laser, which has stronger penetrating ability.

For example, the one around 10μm, but that thing is troublesome to make and takes time. It is also a good choice to use 1.06μm to make laser-guided bombs first.

The difference between having it and not having it is huge.

Mr. Gao is a very nice person. He even solved this problem. Mr. Zhou was very happy. It can be said that with the things provided by Gao Zhendong, the laser-guided bomb is basically formed. At least it can produce a thing with a hit rate far exceeding that of a free-fall bomb.

Seeing that he had basically understood his idea, Gao Zhendong did not go into the technical details, but directly arranged the next step for him to do.

"Mr. Zhang, Mr. Zhou, I'm going to trouble you with the next thing. Prepare the project materials for this laser-guided bomb and report it to the Defense Works Committee. Lu... No, this thing should be under the jurisdiction of the Air Equipment Bureau. They should be interested."

When it comes to the specific implementation, Gao Zhendong has always been a hands-off boss, wishing that he would have nothing to do after he has explained the principles and routes.
