From the beginning of his suspicion of Liu Yijiu, a young comrade, to his admiration at this time, in fact, Liu Yijiu did not make much achievements, but only used his design to tell these old men who were stupid in the mountains that the bullet performance he designed was better than theirs.

Then, the C4 explosives made with his recipe were better than the original, the cloud burst bomb, if Liu Yijiu hadn't told them, they wouldn't even know what this thing was! They didn't think that metal powder could be more lethal than explosives.

This time the war in the southwest has come to an end, and they have come up with the improvement of the original 130 rocket artillery shells and the cloud burst shells of the 336 rocket artillery warheads, and they must have received more praise. All of this is the credit of Liu Yijiu.

If it weren't for Liu Yijiu's whimsical ideas, without his suggestions, they wouldn't be clear at all.

Therefore, if Liu Yijiu proposes to get any ammunition now, they will not question whether this design is reasonable at all, and if it does not achieve the kind of performance they want in time, it can be improved by them in the end. In this way, they have accumulated experience and their thinking is no longer limited.

Before this, there was not much real technology accumulation in China. The little technology given by the USSR has long been digested, and now the countries of the world have significantly more than China with 30 years of experience in ammunition. The technology they got from the USSR, also from the early fifties!

"Director Xiao Liu, you are a distinguished guest, let's have dinner here tonight. Everyone wants you to stay here and have fun together. Seeing Liu Yijiu running here, Feng Yue's wrinkles all over his face bloomed, and this smile made the black-rimmed glasses on the bridge of his nose move up a lot.

He is a technical management officer. For people with technology, it is natural to admire.

"I'm drunk as soon as I get drunk, or forget it......" Liu Yijiu didn't dare to drink, God knows if he would have the habit of talking drunk, in case he said something that shouldn't be said, he had to be caught by some guys in the mountain to do a slice experiment.

Let's hope those guys in the underground base aren't engaged in biological experiments.

"Director Liu, don't say that. When you were only half an old child, you could knock down a lot of people by yourself! Nie Zhibo came over with a stack of drawings in his hand. Hearing Liu Yijiu say that he couldn't drink, he immediately said with a wry smile.

He was no less drunk by this guy back then.

In the past, the base was bitter, but wine was still indispensable, and the conditions were not good. When building the base, everything was built from scratch, and the limited construction was the factory, and while digging into the mountain, the factory began to be built, and the dormitory was not built, so they used some plastic sheeting to tear a shed as a house.

The winter in the mountain is very cold, and the above knows about this situation, so they have gathered a lot of wine here to ward off the cold.

Liu Yijiu was the only child in this base that year. So he became the object of everyone's amusement, and he tricked him into drinking or something since he was a child, and as a result, he practiced the amount of alcohol that this little guy had.

"Uncle Feng. Uncle Nie, don't call me Director Xiao Liu, let's call me Xiao Liu, Director Liu is too angry, by the way, did you get the blueprint of the anti-tank tail shelling armor-piercing projectile I said at the beginning? That's what I'm here to do. The purity of tungsten powder from Mr. Jia's side reached 99.99%, if possible. After secondary processing, it should be possible to achieve a higher purity, which is completely enough for our armor-piercing bullets to use......" Liu Yijiu was worried that the two old men would talk about drinking again, and immediately moved to business.

As soon as they heard this, the two of them immediately frowned.

The tail shell shelling armor-piercing projectile is relatively easy to say, but when they designed it, they realized that this thing was not as easy as they thought at the beginning.

Not to mention the requirements for materials, just to make this armor-piercing projectile achieve a higher ejection speed without a shell, and at the same time, to make this armor-piercing projectile have a stronger armor-piercing ability, they calculated for a long time, various strengths and mechanical properties, and the initial velocity that the propellant charge can provide, are all headaches for them.

"During this time, most of my energy was focused on this, and I have not been able to solve some problems. If tungsten molybdenum alloy is used, the weight of the entire armor-piercing bullet is a little large, and if you want to take off the outer shell during the flight, you can't make the shell too thick and thin, but you can't make the pressure of the propellant reach greater, this is the overall design, and I have discussed it with them many times, and they all think this is too difficult...... "Nie Zhibo handed Liu Yijiu a stack of drawings in his hand, which were all their design sketches of the tail stabilized shell-out armor-piercing projectile.

Liu Yijiu looked at them one by one, but he didn't look at the calculation formulas next to him.

He didn't even know how to make this thing himself.

When the tank arrived at the back, it basically carried all kinds of missiles, and at that time it was no longer called a tank, but a land fire platform, which was mainly used for fire support for ground forces. Small-sized anti-armor missiles are enough.

The reason why he knows this is because he has seen the information.

There are also drawings and also know how it works.

"If it doesn't work, leave this for later study, we can shoot the shells in tandem, so that we don't have to think about the various problems of shelling armor-piercing shells. What about the blackboard here? Liu Yijiu looked around, but he didn't see the blackboard in the office that had been placed here for discussion.

"It's out there. We haven't gotten anything new for us from District 8 yet. Let's go outside......" Feng Yue explained, and the blackboard inside had been moved out.

During this time, they have a lot of tasks and need a lot of blackboards.

When everyone is discussing, they draw a simple diagram on the blackboard, and then several people discuss together, if there are any suggestions, or if they are not sure, make modifications, and then continue to verify......

In this way, a lot of drawings can be saved.

Liu Yijiu followed the two of them outside, only to see that all the blackboards were densely packed with simple diagrams and calculation formulas.

Seeing that he didn't move, Nie Zhibo hurriedly stepped forward to erase an unimportant sketch of the shell design.

Liu Yijiu didn't say anything, picked up the sketch next to the blackboard, and drew a sketch of a tandem armor-piercing projectile, which should be much more difficult to produce than a tungsten alloy tail shell-off armor-piercing projectile.

"The front is a tungsten core armor-piercing projectile, and in the middle is a high-explosive ......," Liu Yijiu pointed to the whole picture to introduce the situation, "Since it is an artillery shell, there is no need to consider adding a rocket engine and propellant in the back." This is similar to the principle of our anti-armor missile, the speed of the shell is provided by the propellant at the back, there is no problem with our technology in this regard, the front armor-piercing part, using high-hardness alloy steel, and the rear part, using high explosives, once the armor-piercing part hits, the back of the high-explosive explosion, the outside shell fragmentation can also destroy the armor, and at the same time will provide power for the tungsten core armor-piercing part of the front speed has been reduced...... "Since the tail shelling is not easy to do, Let's make it easier.

"Can this be achieved? Moreover, how to hit the armor in front of the steel core to make the rear explode, and how to avoid the explosion of the internal explosives when the cannon is ejected, these are all problems......" Nie Zhibo saw this design, and the problem that had been bothering him seemed to have been solved.

However, the tandem armor-piercing blasting projectile in front of him is also relatively difficult to achieve.

"That's your problem. At present, our tanks mainly use rifled guns, and how to consider the progress impact of rotation after the guns are ejected is something that needs to be considered when designing. In addition, the fifth area is already beginning to study smoothbore guns, how to make the performance of artillery shells better under high temperature and high pressure, these are your problems......" Liu Yijiu said irresponsibly with a wink.

Want to do artillery shell research?

It's definitely a very fatal thing.

Liu Yijiu himself is not familiar with this aspect, not to mention, mainly because he has no interest in this at all.

After the war develops, it will be sublimated to the realm of art. Heavy firepower strikes each other with precision, then discharging small groups of assault forces for sweep and finally occupation, these guns are slow, inflexible, long-range, and accurate enough to be targeted.

Of course, this era is still too far away from that, Liu Yijiu can only get some things he knows and let these experts play their strengths.

Precision strike weapons such as missiles are king.

"Xiao Liu, I'm looking for you, why did you kid come here?" Liu Yijiu left a bunch of questions for Feng Yue and Nie Zhibo and was ready to slip away, but he didn't expect Zheng Hao and Wang Shunyi to come here.

After asking, I found out that they were here to attend the dinner in the ninth district. District 9 will continue to work after dinner tonight......

The first batch of people to go back, no matter how far or near, had nothing to do with the busy third and ninth districts.

There is no canteen in the base that can accommodate everyone's meals, so it is natural to have various divisions and regiments.

The chief officers of these bases naturally have to participate, even the heads of other divisions will also come, usually have no business contacts, it is difficult to get together, and the Chinese New Year is the time for everyone to contact each other.

Liu Yijiu doesn't want to stay here, if he stays, he must drink, these old men rarely drink alcohol, but he already knows very well that many guys have a lot of alcohol, and if he is overturned, it will be a big trouble.

In the end, being pressed by Wang Shunyi and Zheng Hao's superiors who could not get out of the masses, coupled with what Nie Zhibo and Feng Yue persuaded him, Liu Yijiu had no choice but to stay...... (To be continued)

ps: There is one more next, and it is estimated that it will be more than three or four o'clock.

Brothers have a monthly pass in their hands, and if the five votes are not yet full, vote for it! Now there are 46 and a half hours left before the end, our advantage is not obvious, don't be blown up at the last moment!

If you don't give a monthly pass, I'll ask the doctor to come to you at night with S75.
