Chapter 1168: Not afraid of stubby, but slender

"Ahem," Li Liqing had to break the awkward atmosphere of the scene. He caught everyone’s attention with a few coughs and said:
Master Wang has opinions on the original engine selection. This is a technical difference. We can slowly demonstrate this matter. Comrade Xiao Tan is here today for From the business perspective, he can give us advice and help. His work is also very busy. Let's not delay his precious time with these specific technical details."
Tan Zhenhua couldn't help being secretly happy, and at the same time a familiar feeling emerged in his heart-as if he had returned to his previous life and sat at the meeting of the technical solution demonstration.
He once had time, just like Zhang Baozhong today. As long as he feels that his plan is right, he doesn’t care who is sitting across from him. He comes up in one breath and catches who is spraying. The elderly version of the military representative Wang Zetian has been sprayed by him on several occasions, throwing hats and tea cups between each other, pointing to each other’s noses and screaming, "Do you know technology?" That is common...
However, in this time and space, he has already avenged himself. I wonder if the scar on his forehead that was smashed by his "flying brick" on Representative Wang's forehead has grown better? Will it hurt if it rains...
Thinking like this, a smile appeared at the corner of his mouth. It was not until Li Liqing called out "Comrade Xiao Tan, Comrade Xiao Tan" to return to his soul before realizing that he had actually deserted, so he couldn't help but apologize: "I'm sorry, I'm sorry. I thought of something just now, so I was a little lost, uh, where did we talk?"
That is, Tan Zhenhua’s current reputation and status are placed there. These top experts who have finally gathered together from all over the world have left him a bit of face. If this is for other young people, at this level He even dared to distract himself at the meeting, and he had to be taught a lesson.
"I just discussed the selection of the engine." After all, it was the foreign aid I invited, and Li Liqing had to come to the field. "Master Zhang and Master Fang have different views on this, but it does not matter. To conduct special research in different categories, let’s ask Chief Master Fang to continue to discuss all the main issues raised by the Pakistan Railway. Many of them are specific technical issues. You are not very proficient in these Comrade Tan, let you know first. The general situation will do."
Tan Zhenhua nodded and expressed his approval of Li Liqing’s arrangement, so Fang Weixian continued to stand up and said: "There is also the firepower delivery system. We have already mentioned the problem of the gun itself, but in fact, apart from the long barrel and insufficient lifespan, In addition, the Pakistani side believes that the types of shells we can choose from are not as many as the Americans. I have seen the catalogues of shells provided by the Americans, M728 and M392A2 shelling armor-piercing shells, M735 tail stabilized shelling armor-piercing shells, M494 anti-personnel grenade, M456 series Armour-piercing bombs, M393 shattered armor bombs, M416 yellow phosphorus smoke bombs and a variety of trainer bombs are all on the sales catalog. Not to mention, at least in the most critical "penetrating bomb" aspect, we provide the first phase of foreign trade There is a considerable gap between the ammunition and the American products, and the actual shooting has proved this. Therefore, the Pakistani railway is skeptical that our tank guns can effectively penetrate the T-72's armor."
"Let me explain this." Another one stood up in the conference room. This one is also as old as Fang Weixian. Of course, this is not surprising. Due to the intermediate fault, the current researchers in China are generally The college students in the 1950s and 1960s are now 50 up?
The one who stood up was thin and wore a pair of glasses. His hair was sparse and his brain was brighter. At first glance, Tan Zhenhua thought it was his father who came to the venue-and this person was happy when he opened his mouth. It's so kind, full of Ningdu flavor!
This person saw Tan Zhenhua's music, and he was also happy, and he said with a smile: "Comrade Xiao Tan seems to have heard it. I am Ningdu-flavored Mandarin, or "Ningpu" for short. Let me introduce myself too. My name is Wang Zheshan. He teaches at Ningdu University of Technology, and his research direction is gunpowder, so he is half expert in artillery shells."
Tan Zhenhua smiled and said, "Professor Wang, it seems that you and I are not only hometowns, but also neighbors. Ningli Technology is just behind our home, and there is a Ningdu Agricultural University in the middle. My home is in a 4014 compound." He also said this. In the tone of "Ningpu", it immediately caused a chuckle in the conference room, which also slightly dilutes the slightly solemn atmosphere just now.
"That's really a neighbor." Wang Zheshan also smiled: "Then when Comrade Tan has time to go home, you must come to our Ningli Polytechnic. Then I will show you around. We Ning Polytechnic. , But there are still many good things hidden."
"Well, then we're settled, I will definitely go." Tan Zhenhua replied, "Also, Professor Wang must be a host and ask me to eat back to the cafeteria of your school. I heard that , Ning Ligong's canteen, especially the legendary "Ligong Braised Pork", is a must!"
"Hahahaha, well, come here, I will invite you to eat in the cafeteria, and make sure that the "Technology Braised Pork" is enough!" Wang Zheshan laughed and agreed, then turned to everyone's direction and said: "Whoever of you is free, I Also entertain according to this standard, but don't secretly say that Wang Zheshan is a poor man who loves riches."
There was a burst of laughter in the conference room again, and the little embarrassment that was left just now disappeared.
After two "Ningdu people" deliberately or unintentionally gagged and adjusted the atmosphere of the meeting, Wang Zheshan finally returned to the topic:
"Speaking of this artillery shell, in fact, when we first introduced the 105 artillery, we also introduced a batch of shells incidentally, but we did not introduce this British artillery from Britain, but made a big bend. It was introduced by Austria. Therefore, it took quite a while to introduce the ammunition, but today is not the time to discuss this matter. I can only say that compared with the American artillery, such as the most typical inter-tank confrontation ammunition. We have to admit that it is backward. I just said that the model that was listed in the sales catalogue by the Americans is M735. I know that this bomb has an initial velocity of 1500m/s, a tungsten alloy material, and a body diameter of 31.68 mm. The body length is 305 mm, and the aspect ratio is 9.6. Based on this estimation, the vertical penetration for homogeneous armor at a distance of 2000 meters should be about 300 mm. This bomb should have been put into production by the Americans around 1978. Yes, the goal is to target the T-72 that had already begun to be equipped in large quantities in Eastern Europe at that time, but this bomb was not the best bomb for the Americans. I think some foreign information has revealed that the Americans have recently developed a "depleted uranium alloy" material. It is said that the length-to-diameter ratio of the new "penetration bullet" of China has been increased to 14. If the initial velocity remains the same, the theoretical penetration depth at a distance of 2000 meters is likely to exceed 350 mm."
Tan Zhenhua asked curiously: "Professor Wang, I can understand what you mean by this aspect ratio. It should refer to the ratio of bullet length to bullet diameter, but is this data important? Listen to what you just said, is it? Can this ratio of length to diameter determine the penetration depth of the bullet?"
Wang Zheshan winked at him and said, "Of course it is important, um, it should be said to be very important, Comrade Xiao Tan, haven't you heard a saying?"
"Uh, what is it?"
"Don't be afraid of stubby, but slender."
"Oh...cough cough cough cough cough..."
