Chapter 246 is like Red Sword-73, but not exactly like it
Seeing the two items added by Gao Zhendong, the other two parties were undoubtedly in a better mood.
Nothing else, these two are very targeted. Except for individual soldiers, I just want to rush to the car to carry them.
The other one explains very clearly the most important technical core of the missile: the guidance technology, which shows that Director Gao really knows what to do with this missile.
What everyone is most unsure about is undoubtedly this guidance technology. To put it harshly, the range and power can be mixed with more water, more water, and more water, and the target can always be reached in the end. It's nothing more than a bigger size and sacrificing portability. This is the only thing that can't be used.
As for the serial armor-piercing warhead, Gao Zhendong didn't mention it.
Because the main combat target of this warhead, explosive anti-armor, is currently only available at home. Taking this thing out in advance will undoubtedly cause trouble for your own people.
Wait until other people have it, and then take it out as soon as possible. The main thing is to not give you a chance to breathe. I will hit you with whatever you have.
Mr. Luo of the Changjian Factory looked at these indicators and requirements and touched his beard: "We do have processing equipment for this rocket engine. After all, the difference between casting explosives and casting fuel is not very big. But we don’t know what it will be like. We lack design.”
Gao Zhendong said: “I’ll take care of this.”
Everyone looked at him, aren't you engaged in materials, artillery, firearms, tanks, armored vehicles and computers? Do you know this?
Hey, what the hell am I thinking? He already does so many things, it doesn't seem strange to have one more.
That is to say, they don’t know everything yet. If they knew everything, they might just run back to the factory and squat down waiting for the drawings.
After all, Gao Zhendong is a person who has designed serious things like stoves.
However, Gao Zhendong is not prepared to do everything, at least in the war department. He is not prepared to extend his hand unless it is absolutely necessary.
Gao Zhendong added: "My idea is to use the warhead as one section, the engine and the missile guidance system as one section, and the two sections can be separated. In this way, the missile storage box will not be too long, making it easy to carry. With the new warhead, the old warhead can be easily replaced, and a little money can be saved.”
The user Fang Hechang Sword Factory thought about Gao Zhendong’s idea for a while, and the more he thought about it, the more he thought about it. I think it's wonderful. If there are many cars, this method will undoubtedly be like taking off your pants and farting, but we have few cars, so that's not the case.
And there are really too many cars. Just remove the storage boxes and assemble the missiles for use. This can also solve many problems.
This split structure is still very useful when you have no money. Manpower is the main consideration in combat, but it is not so easy to use 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.
Times are different, and the requirements and understandings for the same thing are also different.
It’s like Zhuge Wuhou borrowing the east wind in the Romance of the Three Kingdoms. In that era, what was borrowed was the east wind. In Gao Zhendong’s previous life, whoever said that he wanted to borrow the east wind would not know what was flying in the sky. That’s great to say.
What’s interesting is that the equipment life of the Red Sword-73 is much longer than that of the Red Sword-8. The simplicity and cheapness may be the biggest reason, and the beauty of the Red Sword-73 goes beyond this.
Gao Zhendong started drawing on the paper again: "My idea is to divide the guidance system into two parts. The main components of the missile are the command receiving mechanism and the control actuating mechanism. The real guidance system is actually in On the shooter's side, whether it is infrared angle measurement or manual control, the instructions are transmitted to the bomb through wires."
The user has some doubts: "Director Gao, can it be done wirelessly in one step?"< br>
Gao Zhendong shook his head: "In a battlefield environment, the current wireless guidance method is immature and far less reliable than wires."
Not to mention now, decades later, Citigroup will blow infrared focus into the sky. The actual combat performance of the "javelin", which can image in a plane and is ignored after being fired, can also attack the top is hard to describe.
Expensive, cumbersome to operate, difficult to lock, and the range of the top attack mode is anxious.
This thing is far from as sci-fi as in the "COD" series. It can lock on the enemy's tank without even seeing it. , the actual situation is that even if it sees the enemy tank, it still may not be able to lock on.
The Chijian-73, on the other hand, looks very crude everywhere, but basically it works. However, it is indeed dangerous to the shooter or the launcher.
Especially for vehicle-mounted launch vehicles, individual shooters are not so dangerous, because when used as individual ammunition, the launch point and control point can be separated by a considerable distance.
The Changjian Factory has some practical concerns: "Director Gao, what should I do if the line is disconnected?"
This question is very reasonable. We do not have the first-generation ammunition equipped. At first, it could only achieve a flight speed of about 80m/s. The biggest reason was that the wires were broken.
Even when the Chijian-8 was developed, there were dozens of rounds due to disconnection in the early stage. But it is also thanks to the Red Sword-8 that Gao Zhendong knows how to deal with this problem. The flight speed of the Red Sword-8 is 240m/s when it is finalized. This is why Gao Zhendong has no objection to the maximum flight speed among the indicators proposed by the user.
Gao Zhendong smiled and said: "Don't worry, I have a solution. I don't say it will definitely reach the 230m/s on the indicator. Be conservative. 200m/s in the early stage will definitely be no problem."
See Gao Zhendong so confident , when several parties add up, it is decided, and this structure will be used.
One reason why the Red Sword-73 can be equipped for longer than the Red Sword-8 is also its design of dividing the entire system into three parts. This thing is produced in too many quantities and it would be too wasteful to disassemble it all at once. It just so happens that its three-piece design allows it to greatly improve performance at the minimum cost.
Some people have even seen a projectile with an A-type engine, a B-type warhead, and a C-type guidance system put together. In many photos of the Chijian-73, the warhead and the rear half are completely different in color. The difference is not to follow the fashion and play with contrasting colors, but to spell it out.
Don’t talk about spelling it out, just talk about whether it can hit if you shoot it, whether it can penetrate it if it hits it, and whether it can kill you if it penetrates it.
Seeing that everyone accepted this structure, Gao Zhendong continued to talk about the idea of the missile body.
“Thanks to the high flight speed in our indicators, the missile body can provide greater lift. We will make the wings smaller and foldable, so that the volume is as small as possible and the improvement is maximized. Portable performance. ”
The elastic wings drawn by Gao Zhendong are even smaller than the original Red Sword-73. The original elastic wings of the Red Sword-73 are based on its basic flight speed of 120m/s. , but the individual ammunition they developed is much faster, so there is no need for such large wings.
However, whether this flight speed can be achieved depends on the guidance system. The reason why the basic flight speed of the Chijian-73 is not high is not that it cannot fly fast, but that the manual control is too fast to react.
This manual control is different from the "human in the loop" of later TV guidance and other methods. Although it seems that humans are playing a role, in fact, the former relies entirely on humans, while the latter mainly relies on automatic control methods. , people play the role of accurate interpretation and correction.
Everyone agrees with this suggestion and there is no fault to be found.
“As for the rocket engine, I plan to use a dual-thrust engine.”
This is what Gao Zhendong is planning to do. Unlike the Chijian-73, he plans to use double thrust engines for this bomb. thrust.
It should be noted that this dual thrust engine is different from the dual pulse engine. Yes, it was the Citigroup guy who was bragging about it on the PPT, but we implemented it first, which resulted in the dual-pulse rocket motor that their main medium-range air-to-air bomb had a much shorter range than ours.
To put it simply, a dual-thrust engine has two thrusts, but there is only one set of ignition devices. Once ignited, the dual thrusts will be exerted one after another. The ignition time of the second thrust is uncontrollable, and the ignition time of the first thrust is uncontrollable. After the thrust is burned out, the second type is connected.
The double pulse is different. Each section of its fuel has an independent ignition system, so that the second section of fuel can be started when needed and try to maintain the dynamic performance of the missile at the end of the range.
Back to this article, the dual-thrust engine can be understood literally, but everyone does not understand the necessity of using the dual-thrust engine here.
Gong Luo was thinking and asked Gao Zhendong: "Director Gao, what is the use of this dual-thrust engine here? A projectile with a range of several thousand meters does not have high requirements on speed. Is it necessary to add complexity here? "
If there is no benefit, but a pure show of skills, then it is unnecessary in his opinion.
The user representative thinks this is a high-end thing, but high-end is high-end, so what is the use of it? They also followed Luo Gong's words and looked at Gao Zhendong.
Gao Zhendong explained: "We use this mainly for soft launch."
Everyone can't understand this sentence. Can the launch be soft?
"Soft launch? I'm really ignorant about this. Director Gao can teach me." Luo Gong said this not in a sarcastic way, but because he really didn't understand.
But since Director Gao had a nose and an eye when he said it, he must have considered it and was not just talking nonsense, so he simply asked directly.
Don't talk about him. Even abroad these days, they have no concept of soft launch.
Gao Zhendong pointed to the office: "This is for street fighting. Street fighting involves a large number of closed or semi-closed spaces. It is very dangerous to launch missiles directly in such spaces. If you are not careful, you may cause damage to the shooter." Damage."
Considering that this projectile is planned to have separate fire control, Gao Zhendong added: "And it is different from field battles or positional battles. In street battles, the launch and control are separated and are in different spaces. It’s a certain level of difficulty.”
In his previous life, Gao Zhendong saw wars in the Middle East and Africa online. People playing RPGs in front of them didn’t pay attention to the direction of the tail flames. It was common for them to fly several meters away with a burst of fire. I was very impressed. , this can kill people.
