Chapter 377: Development of grenade

After hearing what Zhao Zhongyao said, Chen Dongshan quickly said that he would help Zhang Lianying design a new grenade together.
"Okay, then this task is left to you two. After the design is completed, let me see it first. If you think it can, then produce some first, test it, and see how powerful this grenade is."
"Don't worry, we can design it soon." Zhang Lianying also nodded in agreement.
After Zhao Zhongyao finished speaking, he returned to his office.
"Hmph, these two old guys, don't give them a great deal, they don't know the rules. They don't know the rules. They don't know how to put them on stage. They have to be led by the nose."
Thinking about Chen Dongshan and Zhang Lianying, Zhao Zhongyao felt a little annoyed.
But he also knows that he is a factory director. This kind of thing is to test his leadership ability. If because of this little thing, he finds it annoying to be the factory director, then he doesn't need to be an'official'.
Besides, Chen Dongshan and Zhang Lianying watched Zhao Zhongyao leave, and the two began to talk again.
"Old Chen, what's the matter? We will let Zhao Zhongyao lead the nose in the future, and we have to listen to him in everything."
Don't look at the two old guys pretending to be like grandsons in front of Zhao Zhongyao when they were cleaning. In fact, they were still dissatisfied in their hearts, but they knew that if they insisted on doing the right thing with Zhao Zhongyao, it would definitely not do them any good.
In any case, Zhao Zhongyao is their leader now, and they must listen to the director of the base. This is what Director Liu meant. If the two of them clearly confronted Zhao Zhongyao, it would obviously violate the rules of the base, and Zhao Zhongyao could naturally punish them.
The two old guys are also about to retire. At this time, if you get a punishment, it will have a great impact on your future life, so the two people have to be humans with their tails sandwiched.
But the hatred of Zhao Zhongyao in their hearts increased unabated, and they had regarded Zhao Zhongyao as their enemy. Just can't show it clearly.
When Zhao Zhongyao gave them a task just now, they both looked respectful and obedient, but when Zhao Zhongyao left, the two of them would be revealed again.
"Big man can bend and stretch, we are tolerating for a while, so that we can bring Zhao Zhongyao down in the future." Chen Dongshan is naturally the same, how can he be willing to become Zhao Zhongyao's pawn, and his actions during the day are just pretending.
"Old Chen, I think you are talking big again. What can you do to bring Zhao Zhongyao down? Somehow they are the leaders of the base. Although you and I are experts in final assembly, you are not a tiger in this deep ravine. "Luo Pingyang was bullied by dogs?"
Although Zhang Lianying was also angry, he felt that he could not take down Zhao Zhongyao, and he did not have a strong background. Although there was a leader in the final assembly to speak, he had no relatives with others, and the relationship was not particularly good.
Just like Director Liu was a friend before, but now that people don't help them, how can he fight Zhao Zhongyao.
They know very well that Zhao Zhongyao is now a celebrity in the military industry. Although the two of them are very famous, they are already "expired" stars. Although it is still famous, it is not popular anymore. Even the leaders are not ‘liking’ them anymore.
"Lao Zhang, why are you so pessimistic! What is Zhao Zhongyao? Is it that our two old experts are not as good as his little expert." Chen Dongshan still seems to ignore Zhao Zhongyao. I don't think this kid is great.
"Old Chen, judging from the current situation, we two old experts are afraid that no one likes them at all. Why don't you notice that now the entire military industry seems to be developing younger. Only young military talents can Being valued by the superior leaders, old experts like us, is already in the past tense, no one is paying attention to us anymore."
Zhang Lianying is also very clear about the modernization reform of the country. He knows that the entire country of China is undergoing modernization, as is the military. Modern China is also being built. The military industry in the army is the same, and it is also in the great tide of army reform.
The most important step in the modernization of the Chinese military is the rejuvenation of the cadre team.
This cadre team is not only the active officers in the regular army, but also includes some professional and technical personnel in the military industry. All these senior talents and military commanders must develop in the direction of younger and more knowledgeable people.
And Zhao Zhongyao is undoubtedly a typical representative of this wave of reforms. He has the status of both a university professor and a military industry expert. He is still a young man of only 26 years old. Such talents are in the entire country. It is difficult to find the second one.
Therefore, the military industry in China now naturally attaches great importance to ‘young talent’ like Zhao Zhongyao.
Even this time Zhao Zhongyao was appointed as the director of the'Jianghai Machinery Factory', which was the result of careful consideration by the leadership of the General Armament Department.
For the veteran comrades in the military industry, the higher-level leaders are not embarrassed to let them retire early, and they can only mobilize them as much as possible to make them adapt to the needs of this reform tide.
If these old guys have young ambitions and the determination to do another career, then keep them, but if they feel that they are old and useless, they want to leave opportunities to young people. , Then let them take the initiative to propose early retirement.
Chen Dongshan and Zhang Lianying are representatives of this group of old military workers. The leaders of the General Assembly transferred them to this newly established military industrial base just to test them. Let's see if they are'the old man's ambition is a thousand miles'. They still want to do some more business, or they are really old and don't want to make contributions anymore, so that they can propose to retire early.
In fact, whether a person is a talent or not has nothing to do with age. Young people are not necessarily talents, and older people are not necessarily talents. Although the reform requires a younger cadre team, if an old expert is indeed very talented, a pillar of the country, and a mainstay of a unit, the relevant state departments will not bear his retirement early.
It can be said that China in this parallel world where Zhao Zhongyao was reborn is undergoing a profound technological and institutional change. In such a big wave of sand-washing movement, only real talents can survive, and those duckweed and bubbles that have no real talents can only drift away with the waves of reform.
And there are not many people who can really understand all this. Zhao Zhongyao may be considered one. And Zhang Lianying and Chen Dongshan, the two old guys, couldn't understand all this either. Still complaining in my heart that the leaders do not care about them, mobilizing them to this place where the birds do not shit, and letting them be "bullyed" by a young man!
"Is this all normal! Anyone tells us that we are all old and useless, so naturally we are not liked. What do you want, do you want to be more attractive when you are old? How is this possible. "
"Then let's swallow and let Zhao Zhongyao breathe and drink." Zhang Lianying couldn't swallow this breath.
"Let's do this first! In the future, if there is any chance, we will find a way to rectify Zhao Zhongyao." Chen Dongshan himself did not know how to deal with Zhao Zhongyao, but he felt that as long as he wanted to deal with one person, he would slowly There are some opportunities that I can grasp.
"Old Chen, I think it's an opportunity to develop a grenade this time."
Zhang Lianying is an expert in the development of grenades. He feels that he will definitely be better than Zhao Zhongyao in this respect. As long as he is better than him, Zhao Zhongyao has no say in the development of grenade.
"What do you say, what time do we have to develop a grenade?" Chen Dongshan didn't quite understand what Zhang Lianying meant.
Zhang Lianying walked to Chen Dongshan and patted him on the shoulder and said, "Old Chen, you think, although Zhao Zhongyao is an expert in missile research, he does not necessarily develop hand grenades. Don’t think that grenade is just a small weapon. Weapons also contain great technology. In this respect, Zhao Zhongyao is definitely not as good as us. In this case, when we develop the grenade, Zhao Zhongyao will not have to listen to us. What we want him to do, he doesn’t have to do anything. Do it!"
After listening to Zhang Lianying's words, Chen Dongshan seemed to feel something.
"Well! It makes sense. In this way, when we were developing the grenade, we deliberately embarrassed Zhao Zhongyao, saying that we need various materials to develop the grenade, and then let him help us to make these materials. Now, it will be enough for him. Zhongyao is busy."
Chen Dongshan understood Zhang Lianying's meaning, and he echoed it.
"Okay, that's it. Let's design the drawings first, and then we can embarrass Zhao Zhongyao." After the two muttered for a while, they began to design the grenade drawings on the desk.
In fact, the grenades they designed before were all the most common grenades, just because the grenades in this world are not advanced at all, so the two of them feel that their grenades are already very advanced.
The two discussed what they thought was a very advanced grenade. In fact, it is an iron grenade that delays the fuze. It's just that the grenade designed by the two of them is a little better than the original one. The index fuze was changed to a pull ring fuze. This can make the throwing soldiers safer and more reliable in use.
Of course, the main factor that determines the explosive power of a grenade is the iron sheet that includes the explosive. What material is this layer of iron made of, the explosion effect is different. General iron-skin grenade will only form a few fragments after exploding, while grenades made of some special materials will form a large number of fragments after exploding.
At this point, Zhang Lianying and Chen Dongshan had not even thought of it. They just work on the hardness of the grenades, and they just want to use some harder steel to make the grenades.
This time, the grenade they designed is made of a very hard alloy steel. In fact, neither of them knew about this kind of steel, nor had they seen it. Just casually designed such a material when designing. Fortunately, after the design was successful, Zhao Zhongyao presented a problem.
The development direction of the real grenade was not what Zhang Lianying and Chen Dongshan had imagined. The development goal of modern grenade is to continuously increase the number of grenade fragments. The number of fragments exploded by this grenade will determine the destruction power of the grenade.
The main measures for developing hand grenades in modern society to improve the damage power of hand grenades are: 1. The quality of fragments tends to be miniaturized. Analysis of the damage effect of fragments shows that under the premise of the same energy level, the damage effect of small high-speed fragments is much better than that of large low-speed fragments. Therefore, most of the fragments of various anti-personnel grenades currently in development are between 0.15 and 0.2 g. 2. The number of fragments tends to be more quantified. The number of effective fragments determines the density of fragments per unit area and directly affects the hit probability. It is an important basic principle in the design of grenade to increase the number of effective fragments as much as possible on the premise of a certain bullet quality. 3. The shape of fragments tends to be polygonal. Fragments of different shapes have different penetration capabilities and the amount of energy transferred to the target, and their injury effects are also significantly different. Compared with spherical fragments, polygonal flat fragments have faster attenuation in the tissue and energy transfer. High efficiency, so the damage to biological tissues is much more serious than spherical fragments. 4. Fragmentation speed tends to increase. The size of the fragment velocity determines the strength of the pressure wave and the size of the instantaneous cavity, which ultimately manifests itself in the degree of injury to biological tissues. The test results show that when the fragment mass is 0.1～0.2g and the speed is 1500～1800ms, it can cause a more effective injury effect.
In order to ensure that the grenade achieves the expected best effect, it is necessary to change the material and improve the processing technology to a degree that can be controlled manually. For example, by using full prefabricated or semi-prefabricated fragments to control the number and shape of fragments; adjust the matching relationship between the charge and the projectile to ensure the speed of fragments; improve the shape of the projectile and control the speed of fragments; use plastic or other non-metallic materials to reduce the quality of the whole projectile Wait.
Zhang Lianying and Chen Dongshan naturally don’t know the modern technology level of all these grenades. Their development level is similar to the level of Zhao Zhongyao during World War II in the era before his death, but at the initial level of grenades development. on. No very advanced grenades have been developed at all.
Although Zhao Zhongyao was not an expert in the development of grenades during his lifetime, what he said was that when he was in that world, he was also an army fan. He has been exposed to many kinds of military weapons, whether it is large weapons or small guns and grenade weapons, he has somewhat studied. He also probably understood a little about the explosion principle of the grenade and the materials needed for its development. From this point of view, he had already surpassed Chen Dongshan and Zhang Lianying.
