Chapter 410: The Principle
Listening to Lu Jiadong's words, whether it was Zhu Haifeng or Qin Jingbin, or Dong Fangzhuo, who has studied in the field of ammunition, and other ammunition system developers, as well as other people on the scene, they couldn't help but be stunned, but Lu Jiadong didn't wait for them to be so stunned, and his rigorous and calm words sounded in everyone's ears again:
"I think all comrades know a very simple physics truth, that is, the smaller an object, the less help it encounters!"
After Lu Jiadong said this, he couldn't help but pause, and at this time, the staff of the test site next to him brought over a cup of tea, Lu Jiadong took the tea, nodded gratefully to the staff, and then took two sips of tea, and then pointed to the slender body of the enlarged 100mm armor-piercing projectile on the screen and continued:
"This 100mm armor-piercing bullet uses this principle to position the diameter of the projectile body at 32mm!"
"So fine!" As soon as Lu Jiadong said this, several members of the ammunition system development team present couldn't help but let out a burst of exclamation, although there is no essential difference between the body of the 100mm armor-piercing bullet and the body of the 120mm armor-piercing projectile in terms of appearance, but the image on the display is not as intuitive as in reality after all, and it is magnified, so it is impossible to show all kinds of details and features.
Therefore, when Lu Jiadong finished saying this, several experts who are very good at ammunition couldn't help but be surprised, and even Dong Fangzhuo, who had discovered this before, opened his eyes in surprise, although he saw that the two were different in diameter, but he didn't expect that the 100mm armor-piercing projectile body would be so thin, 32mm in diameter, that is, a little more than three centimeters, you must know that the caliber of the current anti-aircraft artillery is generally above 35mm, and the diameter of the 32mm projectile is not too small.
What's more, such a thin projectile body has great problems in counterweight, stability and air flow disturbance. To put it mildly, even a gust of wind may blow the body of the projectile flying out of the barrel, you must know that in the development of the new 120mm armor-piercing projectile, in order to overcome this problem, the entire ammunition team does not know how much work has been put in, and finally finalized the 53mm diameter projectile.
It's a painstaking process. All the ammunition system developers, including Dong Fangzhuo, have personally experienced it, but even so, they are only surprised but do not question it, after all, the ironclad fact is in front of them, the new 120mm armor-piercing projectile cannot penetrate at all within a range of kilometers, while the new 100mm armor-piercing projectile can easily penetrate the composite armor at the same distance.
If it were an inconclusive technical seminar, there might be different opinions and objections, but now the irrefutable and impressive test has just ended, and that's why. Even if you have the heart to refute it now, it is impossible to say, including Dong Fangzhuo, the ammunition system development personnel are like this, and the same is true for Zhu Haifeng and Qin Jingbin who are next to them.
They would not believe that a projectile body smaller than ordinary anti-aircraft artillery would be like a bamboo pole stabbing tofu, beating the composite armor to pieces, Zhu Haifeng wanted to ask several times, but swallowed it back because of the facts in front of him, and Qin Jingbin also wanted to say and stopped, the facts are the facts. No matter how much you question or refute it, the hard facts cannot be changed.
And what Lu Jiadong wants is such a result. It's not that he can't see the so-called "spear and shield" struggle before, nor is he turning a blind eye to the intensifying confrontation, let alone leaving Zhao Rusong in a bad mood, and the attitude of everyone present turns a deaf ear, and it's not that there is no way to suppress and solve all this series of things with means and the convenience of his position.
It's just that he thinks that if he does this, all the research and development results will be based on means and job assignments. Rapid results may be achieved in a short period of time, but in the future, the boundless thinking of scientific researchers will be completely sealed, and the biology of the Soviet Union is a typical example.
The special period that China has just experienced is also an unavoidable case, so what Lu Jiadong wants to do is to build a good border. As long as these technicians are allowed to give full play to their wisdom and talents, bold innovation and practice, they can stimulate the vitality of the entire scientific research team.
Because in Lu Jiadong's view, the research and development of relevant weapons and equipment cannot be completed by one person, but requires the common wisdom of thousands of scientific research workers, skilled industrial workers, etc., and China has not lacked such intelligent people from ancient times to the present.
Especially in China's current military industrial system, whether it is scientific research personnel or skilled workers, their own foundation is very solid, and they have a unique spirit of hardship and hard work, and what is lacking is new ideas, new ideas and more cutting-edge academic theories, in the final analysis, it is a lack of creativity.
Of course, Lu Jiadong also knows that for some reasons, such a change is bound to be a long and difficult process, but for the long-term development of China's scientific research and production, especially in the field of military research and development, we must be determined to thoroughly implement this line of thinking.
Just like the new 100mm long-rod deshelling tail stabilized armor-piercing bullet explained now, if there is advanced theory to guide and there is pioneering thinking, Lu Jiadong believes that with Zhao Rusong's solid theoretical technology and practical experience, as well as the joint efforts of a large number of scientific researchers who pursue progress, such an armor-piercing bullet model should not be unexpected, but their thinking has not been stimulated for some historical reasons, so they will continue to follow the original old path, and the composite armor of Qin Jingbin and Zhu Haifeng is the same。
It is precisely because of this that Lu Jiadong will act like this, in order to use ironclad facts to make the members of the new tank development team, including ammunition systems and armor systems, change their original inherent thinking, and expand their development ideas, be more bold in innovation, and broaden their horizons.
Of course, Lu Jiadong did not think that he could achieve complete success in doing so, just like after communicating with Wu Tianming last night. Wu Tianming's words:
"Jiadong, your idea is good, but no matter what, you have to eat the food in one bite, and you have to do things step by step, isn't it too anxious to change suddenly!"
on this. Lu Jiadong also admitted that he was indeed a little anxious, but he couldn't help it, he wanted to catch up with the world, wanted the army to become stronger, wanted the humiliation of the year not to be repeated, wanted China to stand up with his waist completely straight, and wanted to complete the dream of military industrial hegemony in his heart. Or sow seeds.
As long as the bricks thrown can be exchanged for small jade pieces, as long as the scattered seeds can grow a few tender green shoots, then he Lu Jiadong will not be a complete failure, because he believes that although the jade pieces are small, they will one day inevitably give birth to a warm and gorgeous exquisite jade, and the new sprouts are not many and small, but one day they will grow into towering trees.
However, Lu Jiadong also knew that this was very risky, not to mention whether there was a deviation in his estimation of 120mm armor-piercing bullets and composite armor, that is, if there was a problem with the hastily produced 100mm armor-piercing bullets, then Lu Jiadong would face an embarrassing situation of disappointment.
And this is what Lu Jiadong is most worried about. But the result of the matter is indeed satisfactory to Lu Jiadong, it should be said that in the face of ironclad facts. Although he has not been completely vigilant, at least all of them have calmed down, and since this is the case, as long as he gives a little guidance, Lu Jiadong firmly believes that with the unique wisdom of China's military scientific research personnel, he will be able to embark on a road of military development with Chinese characteristics.
Therefore, when Lu Jiadong saw Qin Jingbin, Zhu Haifeng, Dong Fangzhuo and other members of the new tank research and development team present, they wanted to stop talking. Or confused, or contemplative, or indescribable, all in all, everyone's eyes are full of a strong desire to explore knowledge**. Seeing this, Lu Jiadong nodded secretly in his heart, and then pointed the screen with his big hand, and his voice was much higher than before:
"The sudden reduction of the diameter of the warhead will inevitably lead to the problem of the counterweight of the projectile, this simple truth should be understood by everyone present, after all, the combat principle of such an armor-piercing projectile, to put it bluntly, is to collide with the armor, if the kinetic energy of the projectile is insufficient, it will naturally greatly reduce the combat effectiveness, and the mass of the projectile body is an important factor in the improvement of kinetic energy!"
As he spoke, Lu Jiadong pulled the small blackboard used for data recording next to him, and then picked up chalk and wrote a few sets of data on it, and then continued:
"Therefore, Professor Zhao Rusong Zhao creatively proposed a small-diameter projectile with a high length-to-diameter ratio scheme, so the 100mm armor-piercing projectile adopts a 12:1 length-diameter ratio, that is, the length of the single body is 14 times the diameter of the bullet, which can not only effectively solve the problem of breeding, but also increase the lethality and strength of the entire ammunition!"
When he heard the words "Zhao Rusong", Dong Fangzhuo couldn't help but be surprised, Qin Jingbin and Zhu Haifeng looked at each other in amazement, and the others nodded in admiration, only Wu Tianming next to Lu Jiadong had an imperceptible faint smile on the corner of his mouth, but Lu Jiadong's words did not stop there:
"Of course, these are far from enough, stability in flight is also very important, the reason why the 120mm armor-piercing projectile seems to be powerful, but the actual performance is mediocre, in addition to the large diameter, low length-diameter ratio, resulting in large resistance, there is also a reason for the use of a three-piece tail structure, although such a structure plays a role in the stability of the projectile, but the corresponding resistance is further improved, resulting in a further decrease in range and strength, so that the overall kinetic energy is insufficient, and then unable to penetrate the armor!"
Lu Jiadong said as he wrote on the blackboard, then turned around and continued to everyone: "The composite armor we developed is the same, if you want to fight similar armor-piercing shells abroad, the defense is obviously insufficient."
It was getting dark, but Lu Jiadong's voice continued to sound in the hall of the main console, and everyone sat around him, no one could have imagined that a fierce collision test would eventually become a lifelong ideological and technical enlightenment lesson (to be continued). )
PS: First, seeing that everyone enthusiastically voted for the monthly ticket for Yuzu, Yuzu was very happy and moved, Yuzu was stupid and not good at words, so he could only continue to kneel and beg for a monthly pass (double monthly pass start and end time: December 29, 2015 0:00 - January 7, 2016 23:59:59), Yuzu first thank you for your support, Mo Da!!
2. "Super Military Overlord Official VIP Group" (group number: five, one, seven, eight, one, one, seven, two, six), I hope everyone will actively join the group to support grapefruit.
3. Recommend a good friend's new book "Science and Technology Inheritance", the author is a bucket of pudding, which tells the story of the experience of obtaining the inheritance of alien science and technology against the sky and the rise of a generation of Chinese science and technology kings!
