Chapter 649 Other Suggestions
Before they were overjoyed, Gao Zhendong said with a smile: "That's about all I have in stock. I also have some suggestions related to the National Defense Work Committee and the Land Loading Bureau. It only makes sense if they are also present to talk about it. What we have here , let’s stop here for now.”
Hearing this, Mr. Fu suddenly remembered that he had a question, and he might be able to find the answer from Mr. Gao.
After all, this person seems to have a variety of fields, whether it is pyrotechnics, materials, fluid mechanics, or something else. They all seem to be quite powerful, but they are really not accurate.
But one thing is for sure: he definitely understands the material, and not just in general!
He quickly said: "Wait a minute, there is another problem we are encountering now, and I would like to consult you."
"Please tell me if I can help you?" Gao Zhendong smiled.
"Bore ablation and wear! After adding medicine, this problem began to become prominent. After all, the amount of medicine was large, and the muzzle velocity of the shell was also high. The original gun barrel technology was a bit unable to withstand it, and the life of the barrel was greatly reduced."
This is the reason why research is difficult. Many parameters and designs are interrelated, and one move affects the whole body.
Gao Zhendong blurted out without even thinking: "The use of electroslag remelting and self-tightening of the barrel can alleviate this problem to a certain extent. If that's not enough, you can coat the inside of the barrel with chromium. It has high hardness and is corrosion-resistant. The price is not expensive and the adhesion performance is good. In fact, with these processes, you can consider lengthening the gun body appropriately, improving the range and accuracy, and combining the howitzer and cannon.”
The length of the gun body is not something you can just add. If you don't believe me, just take an iron bar with a length-to-diameter ratio of more than 30, fix one end, and measure how thick and hard it is so that it won't bend naturally.
Um? Is it that simple?
Um! It's that simple!
Seeing Gao Zhendong solve this problem without even thinking about it, the admiration of the two artillery chiefs was indeed like an endless river.
Add a howitzer? Yes, Lao Maozi said so too. That’s a good idea!
With this mood, a group of people followed Gao Zhendong back to the main venue.
The comrades who were discussing other issues stopped and looked at them.
The army leader smiled and said: "How is it? Comrades, are you confident anymore?"
Mr. Fu smiled and was full of confidence: "I have confidence! Leaders, 18 kilometers! There are many, 18 kilometers!"
Mr. Shao also smiled: "20 kilometers! I guarantee 20 kilometers." It seems that he doesn't want 122 Liuzhuan to be more beautiful than before. Anyway, if you mention a little bit, you can't let your 122 go further than my 152!
The army leader looked at Gao Zhendong, "No, I was joking, are you serious?"
11.8 to 18, more than 50%! It’s even more exaggerated than the 17.4 of the 152mm. When some things reach a certain limit, it is difficult to improve even a little bit.
As for the 152 Polo, it seems that Gao Zhendong has really come up with a lot of good stuff this time. Even the 152 Polo, whose original design cannot be significantly modified, can be improved by more than 10%.
I am still setting up an ambush, Mr. Shao thought to himself.
"Okay, that's it! You all have confidence, so you're welcome! The self-propelled howitzer uses a PT-76 modified universal chassis and is equipped with a 122mm howitzer. The howitzer has a range of not less than 18 kilometers and a burst rate of fire. Less than 8 rounds per minute. Are there any problems?" The Army and the leaders and chief engineers of the National Defense Work Committee exchanged opinions and proposed the final indicators. As for the chassis indicators, they can be put back. The most important thing now is the gun.
The burst rate of fire must be clear. Since we learned from the discussion just now that the artillery detection radar has integrated a new computing device developed by Gao Zhendong, and its response speed will be further improved, this indicator becomes even more important.
Expect the enemy to be lenient. Whatever we have, the enemy will also have it.
"No problem!" Mr. Fu was now confident.
After this matter was settled, Gao Zhendong didn't know what they were discussing just now, but he still had something to say.
"Dear leaders and comrades, I still have some suggestions and ideas regarding artillery. While everyone is here, I will talk about them together. It may not be useful now, but I think it is still meaningful as a reserve or a possibility. ” Gao Zhendong asked to speak.
Both the Defense Works Committee and the Land Loading Bureau are very interested in his suggestions and ideas. Facts have proved that his ideas are quite useful.
"You say it, say it openly." The leader of the National Defense Work Committee smiled.
"Well, I have a lot of ideas. It may be confusing to talk about. Please bear with me." Gao Zhendong took a precaution first.
The army leader looked contented: "It's okay, just say it and they will take care of things."
He has been in this mood ever since he decided on this 18km122 self-propelled howitzer.
Gao Zhendong looked at his notebook and sorted out his thoughts.
Everyone looked at his notebook and were curious about what was written on it.
Not even a fiber can escape from Gao Zhendong's notebook! The leaders of the National Defense Working Committee secretly felt cruel.
"Let's start with the self-propelled 122-gun. Although the range of the 122-gun has now caught up with the 152-gun, this is only temporary. With the development of technology, the range of the 122-gun will eventually be inferior to the 152-gun..." Mr. Shao nodded fiercely, yes, yes, that makes sense.
"So I propose to build 122 first. This is from the perspective of temporary sufficiency, technology pilot, and cost saving. After the completion of 122, we will eventually put 152 on the agenda. This is a point that must be carried out in the long term. .”
He just mentioned this to express his attitude. He believed that even if he didn't say it, the troops would be eager to take up this matter.
"But at the same time, I suggest that another thing should not be left behind, a large and medium-caliber rocket launcher! Medium and long-range."
Our 107 Fire is indeed a classic. To be honest, if we hadn’t fought guerrilla warfare for ten or twenty years, we wouldn’t have been able to come up with such a magical thing. It’s so suitable for guerrilla warfare.
However, for regular army operations in large corps, the 107 fire is obviously not enough. Even its enlarged version of the 130 fire is too short. Needless to say, there is nothing else to say.
A comrade from the Land Loading Bureau said: "In addition to the 107-fire launcher, we are also currently working on a 130mm rocket launcher."
Theoretically, Gao Zhendong didn't know that this thing existed, so he thought that Gao Zhendong didn't know that it existed, so he made the suggestion.
Gao Zhendong didn't know: "Great! What's the range? The advantage of the rocket launcher is that it can increase the range at a relatively low cost."
If the accuracy of a rocket launcher is not considered, it is relatively easy to increase the range. Just pile up propellant! It is much easier to stack propellant than a barrel gun to stack propellant.
This sentence made the comrade of the Land Loading Bureau look embarrassed. He glanced at the leader of the Army.
The army leader smiled: "Speak! Whatever Comrade Zhendong wants to know, just say it."
However, the comrade from the Land Installation Bureau was not embarrassed about the issue of confidentiality. He was embarrassed about what he wanted to say.
"Uh... 10 kilometers of 130... 8 kilometers of 107." It's still being worked on. There may be some differences in finalization, but it won't be too big.
Only then did the other comrades realize what he was embarrassed about. He might as well be in charge of an artillery piece. The old 122 melons had 11.8. Moreover, the degree of overlap between the two cannons is ridiculously high.
Gao Zhendong continued to pretend: "Oh, it seems that the two are very repetitive..."
"Haha, it's a bit." There is really no qualitative difference between 8 kilometers and 10 kilometers.
Gao Zhendong directly put forward his own suggestion: "If this is the case, I suggest retaining the 107. We do need a rocket launcher with excellent maneuverability, even if the range is lower. But for the 130, I suggest starting over with the same caliber. , extend the length and increase the range to 40 kilometers! You have to get on the car anyway, so why not make it bigger?”
Nothing can happen to this big baby, the 107. You must keep it, but for the 10-kilometer 130, you might as well get a big one.
As for the 130, the original design felt like a big car carrying a small cannon. Gao Zhendong knew this very well.
Damn it, this satellite was zoomed in, and the whole place was in an uproar.
Gao Zhendong explained: "Actually, this improvement is easier than raising the 122 rocket from 11.8 to 18, because the rocket can be lengthened, and I can also help improve the propellant, let alone 130, assuming that other indicators remain unchanged. Next, it is not difficult to increase the 107 to 10km. No matter what level the current 130 is placed in, it cannot change the fact that it can actually only shoot 10 kilometers. This range is too limited for tactical use. "
130 can hit 40km, as long as the length is enough, it is not a problem at all. In the future, the 122fire will also have a 40km range.
For Gao Zhendong, you can only hit 10 kilometers. Where should I put the non-sensitive bombs? After all, barrel guns can only hold 1 or 2 submunitions, and their effectiveness against group targets is much worse than rocket launchers. The 10-kilometer rocket launcher directly lost its ability to attack the enemy's deep mechanized groups.
I have deployed a remote spreader in the air, but it is not as flexible as having it myself when the plane comes to throw it.
After listening to Gao Zhendong's suggestions and explanations, the National Defense Work Committee and the Land Loading Bureau fell into deep thought. Yes, 10 kilometers is enough for what. Using rocket launchers to suppress enemy artillery. If you want to complete this task at this range, it is undoubtedly a bit of a joke. , even suppressing large-caliber mortars is difficult enough.
And Gao Zhendong's reasons are very good. He really knows how to change the propellant. The National Defense Working Committee is well aware of this matter.
In fact, for 130 fires at 10km, the Army is willing to do so? That's definitely not the case, but there's nothing we can do about it.
Since Gao Zhendong has the ability to increase the range of the 107 to 10km, then the current 130 is basically completely meaningless. Even if it can be improved a little, such as to more than 12 kilometers, what is the use?
The Army, the Land Loading Bureau, and the Defense Industry Committee discussed this matter and Gao Zhendong's suggestion was indeed worth considering.
"We have written down this matter and will work on it. What are your other suggestions?" the leader of the National Defense Work Committee smiled. Although he thought Gao Zhendong's words were very reasonable, this problem certainly cannot be solved here.
