Chapter 246: Like Red Sword-73, but not completely

Seeing the two additional points added by Gao Zhendong, the other two parties were undoubtedly in a better mood.

There is no other reason. These two items are very targeted. Except for individual soldiers, I just want to go for vehicle transportation.

The other one explains the most important technical core of the missile: the guidance technology, which shows that Director Gao really knows how to make this missile.

What everyone is most unsure about is undoubtedly the guidance technology. To put it bluntly, the range and power can be adjusted by adding more water and mixing more water, and the indicators will always be met in the end. It's just that the size will be a little bigger, sacrificing the portability indicator. This is the only thing that can't be made up like this.

Gao Zhendong did not mention the tandem armor-piercing warhead.

Because the main combat target of this combat unit - explosive reactive armor, is only in his own home, taking this thing out in advance will undoubtedly cause trouble for his own people.

Wait until others have it, then take it out as soon as possible, focusing on one thing and not giving you a chance to breathe. I will use whatever you have.

Mr. Luo from the Changjian Factory looked at these indicators and requirements and stroked his beard. “For this rocket engine, we do have processing equipment. After all, there is not much difference between casting explosives and casting fuel. But we are not too clear about what it should be processed into. We lack the design.”

Gao Zhendong said: "I'll take care of this matter."

Everyone looked at him and asked, "Aren't you good at materials, artillery, guns, tanks, armored vehicles, and computers? You can do this, too?"
Ugh, what the hell was I thinking? He already has so many things going on, one more doesn't seem strange.

In other words, they don’t know everything. If they knew everything, they would probably run back to the factory and wait for the drawings.

After all, Gao Zhendong is a person who has designed even such niche things as stoves.

However, Gao Zhendong is not prepared to take charge of everything, at least when it comes to the combat department, he will not get involved unless it is absolutely necessary.

Gao Zhendong added: "My idea is to separate the warhead into one section and the engine and guidance system into another section. In this way, the storage and transportation box of the missile will not be too long, which is convenient to carry. Moreover, the new warhead can easily replace the old warhead, which can also save some money."

The user and Changjian Factory thought about Gao Zhendong's idea for a while, and the more they thought about it, the more wonderful it seemed. If there were many cars, this method would undoubtedly be like taking off your pants to fart, but we have few cars.

And if there are really too many vehicles, we can simply remove the storage and transportation boxes, assemble the missiles and use them, which can solve many problems.

This split structure is quite useful when you have no money, as manpower is the main consideration in combat. However, it is not so useful when you have money, after all, the preparation time for combat is slightly longer.

The technical and tactical indicators of any equipment must be viewed in light of the times.

Different times lead to different requirements and understandings of the same thing.

It is just like the story in the Romance of the Three Kingdoms where Zhuge Liang borrowed the east wind. In that era, what he borrowed was the east wind. But in Gao Zhendong's previous life, whoever said he wanted to borrow the east wind, it is hard to say what was flying in the sky.

Interestingly, the equipment life of the Chijian-73 is much longer than that of the Chijian-8. Simplicity and cheapness may be the biggest reason for this. However, the advantages of the Chijian-73 are more than that.

Gao Zhendong started drawing on paper again: "My idea is to divide the guidance system into two parts. The missile mainly consists of the command receiving mechanism and the control actuation mechanism. The real guidance system is actually on the shooter's side. Whether it is infrared angle measurement or manual control, the instructions are transmitted to the missile through wires."

The user had some doubts: "Director Gao, can we do it in one go and use wireless?"

Gao Zhendong shook his head: "In battlefield environments, the current wireless guidance method is immature and far less reliable than wires."

Not to mention now, even decades later, the "Javelin", the infrared focal plane imaging missile that the United States boasts about and can attack the top even if it is left alone after launch, will have a hard time describing its actual combat performance.

Expensive, cumbersome to operate, difficult to lock, and limited range in top attack mode.
This thing is far from being as sci-fi as in the "COD" series, where you can lock onto the enemy's tank without even seeing it. The actual situation is that even if you see the enemy's tank, it may not be able to lock onto it.

The Red Sword-73, on the other hand, looks quite simple in every way, but it is basically still functional. However, it is indeed somewhat dangerous for the shooter or the launcher.

Especially for vehicle-mounted launchers, individual shooters are not so dangerous because when this thing is used as an individual bullet, the launch point and the control point can be separated by a considerable distance.

The Changjian Factory had some practical concerns: "Director Gao, what if the line breaks?"

This question makes a lot of sense. The first generation of missiles that we were not equipped with could only achieve a flight speed of about 80m/s at the earliest. The biggest reason for this was the breakage of the wires.

Even when the Red Sword-8 was being developed, dozens of rounds were lost in the early stages due to line breakage. However, thanks to the Red Sword-8, Gao Zhendong knew how to deal with this problem. When the Red Sword-8 was finalized, its flight speed was 240m/s, which is why Gao Zhendong had no objection to the maximum flight speed in the indicators proposed by the user.

Gao Zhendong smiled and said, "Don't worry, I have a solution. I don't say it must reach the target of 230m/s, but to be conservative, 200m/s will definitely be no problem in the early stage."

Seeing that Gao Zhendong was so confident, the parties discussed it and decided to use this structure.

One of the reasons why the Red Sword-73 can be equipped longer than the Red Sword-8 is that it is designed to divide the entire system into three parts. There are too many of these things produced, and it would be a waste to remove them all at once. Coincidentally, its three-part design allows it to greatly improve its performance at the lowest cost.

Someone even saw a missile with a Type A engine, a Type B warhead, and a Type C guidance system put together. In many photos of the Chijian-73, the warhead and the back half are completely different colors. This is not a trendy color contrast, but a combination of these.

Don't even mention whether you can fight it out. Just think about whether you can hit the target when you shoot it, whether you can penetrate the target if you hit it, and whether you can kill the target if you penetrate the target.

Seeing that everyone accepted this structure, Gao Zhendong continued to talk about the concept of the projectile.

"Thanks to the higher flight speed in our target, the missile body can provide greater lift, so we made the wings smaller and foldable, so that the volume is as small as possible and the portability is improved to the greatest extent."

The wings drawn by Gao Zhendong are even smaller than those of the original Chijian-73. The wings of the original Chijian-73 were based on the flight speed of its basic model of 120m/s. However, the individual missile they developed is much faster, so it does not need such large wings.

However, whether this flight speed can be achieved depends on the guidance system. The reason why the basic model of Chijian-73 does not have a high flight speed is not because it cannot fly fast, but because the manual control cannot react in time if it flies too fast.

This manual control is different from the "man in the loop" of later television guidance and other methods. Although it seems that people are playing a role, in fact, the former relies entirely on people, while the latter relies mainly on automatic control methods, and people play a role in accurate judgment and correction.

Everyone agreed with this suggestion and found no fault with it.

"As for the rocket engine, I plan to use a dual-thrust engine."

This is the trick Gao Zhendong is going to play. Unlike the Chijian-73, he plans to use double thrust on this missile.

It should be noted that this dual-thrust engine is different from the dual-pulse engine. Yes, it is the dual-pulse rocket engine that the Citigroup guy boasted about in the PPT, but we realized it first, resulting in their main medium-range air-to-air missile having a much shorter range than ours.

Simply put, the dual-thrust engine has two types of thrust, but only one set of ignition device. Once ignited, the dual thrusts will be exerted one after another. The ignition time of the second thrust is uncontrollable. When the first thrust is burned out, the second thrust will be connected.

The dual-pulse is different. Each stage of fuel has an independent ignition system, so that the second stage of fuel can be started only when needed, so as to maintain the missile's dynamic performance at the end of the range as much as possible.

Back to this missile, the twin-thrust engine can be understood literally, but people do not understand the necessity of using the twin-thrust engine here.

While thinking, Luo asked Gao Zhendong: "Director Gao, what is the use of this dual-thrust engine here? For a missile with a range of several thousand meters, there is no high requirement for speed. Is it necessary to add complexity here?"

If there is no benefit and it is just a show of skill, then in his opinion it is unnecessary.

The user representatives thought that this was a high-end item, but it was high-end, so what was the use of it? They also followed Luo Gong's words and looked at Gao Zhendong.

Gao Zhendong explained: "This is mainly used for soft launch."

No one understands this sentence. How can the launch be soft?

"Soft launch? I am really ignorant about this. Director Gao, please enlighten me." Engineer Luo said this without any sarcasm, but he really didn't understand.

But since Director Gao spoke so convincingly, it seemed that he had considered it and was not just talking nonsense, so he just asked directly.

Not to mention him, even abroad these days, people have no idea about soft launch.

Gao Zhendong pointed to the office and said, "This is for street fighting. Street fighting involves a large number of closed or semi-closed spaces. It is very dangerous to directly launch missiles in such spaces. If you are not careful, it may cause harm to the shooter."

Considering that the missile is planned to be separated from the control, Gao Zhendong added: "And unlike field or positional warfare, in street fighting, it is difficult to separate the launch and control and place them in different spaces."

In his previous life, Gao Zhendong saw wars in the Middle East and Africa on the Internet. It was common for the people firing RPGs in the front to not pay attention to the direction of the tail flame, and to be blown several meters away by the fire. He had a very deep impression of this, as it could be fatal.
