Chapter 647 is all ready
And there are more than one safety hazards. One is that it is easy to burn the gunner, and the other is that the fire is soaring into the sky. Combined with the 10-kilometer range, it is very easy to be discovered on the plains, especially at night, as if the sun is shining. This problem is not only faced by 122, but also by 152.
So both parties were attentive and nodded. The reason is correct, and we know it, but how to solve it?
Seeing that they recognized this analysis, Gao Zhendong felt relieved. It was hard to say anything else. There was still a solution to this problem.
"Under the condition that the expansion rate is basically the same, if the burning rate of the propellant reaches XXm/s, will it be enough for you?" Gao Zhendong didn't do other fancy things and just took the fuel out of the cauldron. The combustion is not complete, right? I'll give you one that burns quickly.
"How much?" Mr. Fu asked again, but Mr. Shao didn't believe his ears.
"XXm/s!" Gao Zhendong repeated again.
Before Mr. Fu could answer, Mr. Shao was happy: "That's enough! That's enough!"
Mr. Fu glanced at him, "You have solved my problem. Why are you so excited?"
Then he turned around and said: "It's enough, it's enough!"
Mr. Shao curled his lips, why don't you take off your pants and fart?
Mr. Fu added: "If we could have this fast-burning propellant, we wouldn't have to be in such a dilemma. We have tried our best to find a solution on the structure and barrel, but we can't solve it."
This kind of problem that can be solved directly from the bottom of the pot is often difficult to solve using other methods. It is a typical example that those who can solve the problem will not find it difficult and those who will not.
Gao Zhendong smiled: "That's easy to handle. I'll give you a unit later. You can ask the committee for a permit and ask them for smokeless propellant. The burning rate meets this requirement. Others may need to be improved, but There are not many areas for improvement. You should try to change it yourself first, and come to me if you have any problems.”
Changjian Machinery Factory, they have the high-burning rate propellant that Gao Zhendong finally improved. It is used for 61 fire, and it is not much different from propellant.
To be honest, Gao Zhendong didn't understand why the Institute of Guidance and Research received news of new propellants so long ago, but 122 and 152 could not. Maybe it was because the equipment technology levels were different.
When talking about smokeless double-based pyrotechnics these days, the main ingredients are those two things, nitrocellulose and nitroglycerin. They are cheap and plentiful. As long as the parameters are suitable, they can basically be used.
It is estimated that they will not come to me. This is not much different from the ready-made answer.
Um? Gao Zhendong's words made the two artillery managers dumbfounded. Is there actually a ready-made bargain?
Not to mention them, the comrades in their team were also confused.
Is it that simple?
However, they did not doubt that Gao Zhendong was lying. If they could give out the specific burning rate first, it would prove that he really had the goods.
"Okay! Okay! Great! Chief Engineer Gao, thank you."
The two of them kept thanking Gao Zhendong. Even if Gao Zhendong just revealed a piece of news to them, it would still be worthy of their gratitude. This news was too important.
What's more, after listening to Gao Zhendong's words, I knew that he was the one who created this propellant and included improvements. This was really thoughtful.
Gao Zhendong did not stop: "The medicine chamber can be enlarged normally, and the problem that comes with it is naturally the need to withstand the structure and weight of the gun body caused by the high chamber pressure, such as the rear seat, the thickness of the barrel wall, etc. , right?”
Mr. Fu and Mr. Shao couldn't help but nod.
Mr. Fu looked at Lao Shao and felt something was wrong: "Old Shao, please click something. You haven't enlarged the pharmacy. Aren't you imitating Lao Maozi's 152? How can you increase the demand for the pharmacy?"
Lao Shao smiled and said: "This is a principled conclusion. We can discuss it if there is any need." Well, if I don't add it now, it doesn't mean I won't add it in the future.
Besides, if the problem of withstanding high chamber pressure can be solved, the gun weight can also be reduced while other conditions remain unchanged.
Regarding the nonsense between their colleagues, Gao Zhendong expressed his joy in hearing about it.
He just stated his solution to this problem: "To strengthen the gun body, the first thing is the gun barrel. I have just heard about the gun steel selection and craftsmanship of your gun body. My suggestion is that you contact the National Defense Working Committee and communicate with Coordinate with the Grassland Tractor Factory and ask them for electroslag remelting gun steel and self-tightening technology for the gun barrel.”
"The combination of these two technologies can greatly improve the bore pressure performance of the artillery while keeping the gun weight unchanged. These two processes have been put into use on tank guns for more than a year. They are very mature and have very good effects. You guys Even if it needs improvement once you get it, it can be done quickly.”
Numb, numb, completely numb, this is how Mr. Fu and Mr. Shao feel now.
It turns out that problems that are very difficult to solve in my own eyes are things that have been solved for a long time and are practical in others' eyes.
However, Mr. Fu was a little worried: "General Engineer Gao, will there be any difficulties? Isn't it inappropriate to have such a red mouth and white teeth?" These days, people are not so particular. Gao Zhendong shook his head: "There is nothing inappropriate. Just say it’s what I meant, and there’s nothing wrong with it.”
Got it, it’s your fault again! No wonder you talk about these things so dearly.
If he had not made significant contributions to these two technologies, it would be impossible to have such a right to speak and say this in such a relaxed tone.
To be honest, the two of them had never even heard of Gao Zhendong's name before today. Now that they had a little contact, they realized that this is a treasure!
I don’t know where the National Defense Work Committee recruited this comrade.
Before the two of them finished expressing their feelings, Gao Zhendong added: "As for the rear seat, I can't provide much help. I believe you are more professional than me, but you can still help with materials. Over there at the Prairie Tractor Factory , I have customized a batch of materials for them, including engine block materials that work in high temperature and high pressure environments. You can ask them for a list. It may be helpful to you, such as hydraulic anti-recoil.”
The oil cylinder and the cylinder are all cylinders, there is nothing wrong with them.
The two of them were even more in awe when they heard this, custom-made materials! This is not a simple job. When it comes to custom parts, they may not have such a deep experience, but materials are easy to customize?
If you go to the 17th Machinery Department with this kind of request, and they still smile and talk to you after hearing it, they are considered polite.
Department 17: Who do you think we get most of our materials from?
Mr. Fu smiled and said: "General Engineer Gao, what you said is wrong. Isn't this helpful? Our biggest headache now is materials! There are some structures that we dare not design, and that's the problem! Thank you very much. .”
Gao Zhendong smiled and said: "No need to thank you, I am an infantryman and have fought abroad. What you are doing is supporting us."
This is not surprising, the two of them thought, no wonder he was so concerned about artillery. He threw out all kinds of advanced technologies as if they were free of charge. It must have been a shame to suffer the loss of insufficient firepower back then.
——All fear comes from insufficient firepower.
Without saying a word, Mr. Fu patted his chest: "General Manager Gao, don't worry, with the technologies you mentioned, I am confident that I can make a good 122!"
Gao Zhendong smiled and said: "Thank you very much. We just talked about enlarging the medicine chamber and strengthening the gun body. Next, there is another one, which is to improve the projectiles."
He gave so much! Mr. Fu and Mr. Shao both have the feeling that if they have these technologies and still can't make good use of them, then they really won't be able to meet Jiangdong's father.
The two of them felt that the pressure on their shoulders suddenly increased.
Gao Zhendong didn't know how they felt in their hearts, so he joked: "But this improvement only has principles and no ready-made technology. You have to think of your own solutions, haha."
Mr. Fu felt a little embarrassed: "General Manager Gao is joking. We can always eat ready-made food and have a rationale. We are very happy. It's good to have a road, but we are afraid of being cornered. That feeling is too uncomfortable."
Gao Zhendong smiled: "Well, it's actually not difficult. In terms of projectiles, there are mainly two suggestions and an outlook."
Tsk, tsk, tsk... A place as small as a cannonball can be used as a dojo inside a snail shell, and so many tricks can be done. But this thing seems to have nothing to do with the material, right? Do you even understand this?
Gao Zhendong: I understand!
"You said, we will remember it." Mr. Shao unknowingly used honorifics to address Gao Zhendong. Although this man is much younger than himself, as the old saying goes, there is a hierarchy of knowledge and expertise. Those who achieve first come first.
Gao Zhendong drew a date pit shape with one end cut off on the blackboard: "The first suggestion is to change the bullet type to a date pit type. This shape can fly farther. Of course, it is not without disadvantages and the accuracy will be poor." It depends on your choice. You have to figure out the specific design bit by bit. And for guided munitions that may appear in the future, this problem will not be a problem.”
The jujube nuclear bomb body, one of the earliest means we used to increase the range, has flaws, but it is not unusable.
Mr. Fu and Mr. Shao don't care much about this flaw. It would be nice to increase the range. To put it bluntly, as long as the range of the cannon used for coverage and suppression is enough, what kind of bicycle do you need?
It's not that it can't be used even if it's close, because it's not very accurate to begin with!
As soon as Gao Zhendong put forward this suggestion, they simulated and imagined the flight of the cannonball in their minds. This thing seemed to really increase the range! Worth a try!
"Well, we will process an extra batch later and try out various shapes!" Mr. Shao said with a smile. We can still afford this small amount of R&D funds.
Gao Zhendong smiled and said: "In fact, when you conduct experiments, you can cooperate with the comrades who are engaged in gun position detection and calibration radars. They have also conducted experiments, and your experiment efficiency will be much higher."
The gun position reconnaissance radar is still being improved, at least the work of integrating the hardware multiplier has not been completed, and it did not take long for them to obtain this thing.
Combining the two means that comrades engaged in artillery detection radars do not need to look for artillery shells everywhere, and comrades engaged in artillery do not need to look for artillery shells everywhere.
Once the gun is fired, the gun detection radar can roughly know the range and impact point of the projectile.
