"Bang~~"

In the evening, Zhu Haifeng, who had just returned to the dormitory of the Wanshan Factory's weapons and equipment comprehensive inspection and testing site, just pushed open the door and threw the black briefcase in his hand on the coffee table beside him, his already somewhat dark face was even more gloomy and could drip water, and the muscles of his jaw were also swollen from time to time, and even the sound of grinding his teeth could be heard from the gap between his lips, and the corners of his mouth were slightly upturned at this moment, and he said coldly with annoyance:

"This Zhao Rusong is simply too deceitful!"

"Old Zhu, you dissipate your anger, dissipate your anger" Qin Jingbin, the director of the Materials Research Institute who came in with Zhu Haifeng, quickly closed the door, and then pulled Zhu Haifeng to sit down, and then said while pouring water:

"It's all for work, there's no need to be so angry, come, drink saliva to suppress the fire"

"For work?" Zhu Haifeng took the hot water handed over by Qin Jingbin, but he didn't drink it, but put it on the coffee table in front of him with a "bang~", and continued angrily:

"Have you seen anyone like him who works for the sake of work? I respect him as an older generation of military industry experts and don't care about him, but if you look at him today, how can he be responsible for the older generation of experts? He even openly accuses Zhu Lao, I think he Zhao Rusong can't even catch up with half of Zhu Lao's mistakes, but a third of Zhu Lao's."

As he spoke, Zhu Haifeng's voice suddenly rose, patted the armrest on the seat with his hand, and scolded Zhao Rusong, just this afternoon's composite armor briefing, when Zhao Rusong arranged Zhu Haifeng's most respected mentor Zhu Guangrong with indifferent arrangements, Zhu Haifeng, who was already on fire, could no longer suppress the anger in his heart, and suddenly burst out like a volcanic eruption. And Zhao Rusong is also a strong temper who does not admit defeat, and the two of them have a fierce quarrel under Mai Mang, if it weren't for Lu Jiadong to stop it in time, the two would have started directly.

Although later, under the persuasion of Lu Jiadong and Wu Tianming, the two eased up somewhat, and they reluctantly sat down to eat together at dinner. But the mustard of the two did not disappear from this, so they talked about the development project they undertook at the dinner table aggressively:

Zhu Haifeng said that composite armor is equivalent to more or less old-fashioned steel homogeneous armor, and Zhao Rusong on the other side said that the anti-tank ammunition he developed can penetrate thicker steel armor than this; Zhu Haifeng said that the performance of the composite armor he developed is equivalent to that of the Soviet-made T-72 frontal armor, and Zhao Rusong will immediately reply that the ammunition he developed can easily penetrate the T-72's frontal armor from a distance of one kilometer.

In this way, the more the two of them talked, the more targeted they became, seeing that the anger was gradually rising, Lu Jiadong and Wu Tianming immediately stood up and persuaded the two of them, and a good dinner broke up unhappily, and Zhu Haifeng, who was full of anger, had nowhere to vent. In the end, he could only go back to the room where he was staying and confide in Qin Jingbin the unhappiness in his heart:

"What kind of ammunition can he Zhao Rusong develop? It is nothing more than the current mainstream armor-piercing bullet, but this kind of anti-tank ammunition may be useful for all-steel homogeneous armor, but it will not play any role in our composite armor, you must know that the chromium jade steel in the interlayer is a ceramic material, and the metal jet of the armor-piercing bullet may be able to melt steel, but it is basically ineffective against ceramics, not to mention that there are two pieces of 68mm thick chrome jade steel installed in the front and back of the composite armor we developed, even if his armor-piercing bullet is strong, it can withstand it!"

"That being the case. Then old Zhu, what are you angry about!" After Zhu Haifeng finished speaking, Qin Jingbin on the side opened his mouth and continued to persuade. It's just that when it comes to composite armor, the look on his face looks a little more confident than Zhu Haifeng:

"Not to mention the armor-piercing bullets, even the armor-piercing shells currently in service, our composite armor can also withstand it, anyway, there are 20mm and 80mm thick 603 armor steel as panels, and two pieces of 68mm thick chrome jade steel are used in the middle. Coupled with the 36mm thick phenolic fiberglass, the overall performance is even stronger than the frontal armor of the T-72 tank!"

As he spoke, Qin Jingbin also had a confident smile on the corner of his mouth, with a relaxed and complacent look, he picked up the water glass beside him, took a sip and moistened his throat, and then continued:

"Didn't we calculate before we came, the overall density of the entire composite armor is 2.83 tons \ cubic meters. If the horizontal thickness is nearly 580mm when the tilt angle of the simulated tank armor arrangement is placed, the protection capacity against armor-piercing shells is nearly 400mm, and the protection capacity against armor-piercing bullets is even more than 580mm, such protection capabilities are unique among many active tank armored vehicles in China, so you can rest assured that our shield can be pierced with any spear!"

Listening to Qin Jingbin's words, Zhu Haifeng's face also had a relaxed look, and he leaned back in the chair and nodded approvingly: "That's!" Originally, the original design of the composite armor that Zhu Lao gave us was already very advanced, and we improved it on this basis, only stronger and not weaker, what is it called standing on the shoulders of giants, the composite armor we developed is the best example, he Zhao Rusong is still not convinced, then let him take those sets of iron spears that are so dazzling tomorrow to try it out, let him see with his own eyes how his so-called spear was blown away by our armored shield!"

"It's also that Professor Zhao is too calm! The ammunition he developed has neither advanced reference nor breakthrough innovation, it is nothing more than using the increase in caliber to improve the power of ammunition, but the key is that the current new 120mm tank gun is still under intense development, and so far not even a prototype gun has been made.

In the end, we have to use the 100mm rifled tank gun on the Type 59 tank to test, but this is just an itch in our boots for our composite armor, and because of this, in my opinion, Professor Zhao is just talking about it, and he can't get the actual thing, so he can only do this!"

As soon as Zhu Haifeng's words fell, Qin Jingbin on the side took the conversation, although his words seemed to be fair and objective comments, but the smug smile on his face made his words sound more like Qin Jingbin was celebrating a long-awaited happy event, and in fact, Qin Jingbin really thought so in his heart.

After all, in his heart, what he is most worried about is that in addition to someone who may jump out and drag his feet, the rest is the so-called new tank fire system, specifically the new 120mm tank gun developed by Wanshan Factory, anyway, Qin Jingbin has participated in the development of 52 times the caliber 155mm howitzer, and is very clear about the artillery research and development level and manufacturing capacity of Wanshan Factory, and also firmly believes that it can manufacture a tank gun with first-class performance.

If he really encountered a new tank gun made by Wanshan Factory during the test, Qin Jingbin was not too sure about the composite armor he developed, but fortunately, the new tank gun of Wanshan Factory had not yet been developed, which made his worries instantly thrown out of the clouds.

Coupled with today's-for-tat confrontation between Zhu Haifeng and Zhao Rusong, it also helped to curb the things that made him suspicious, and the rest was a live-fire test tomorrow that was as easy as a party performance, so that his academician title could basically fall on his head, such a scene was extremely pleasant to think about, and Qin Jingbin was naturally no exception.

It's just that his unprovoked joy didn't last long, and Zhu Haifeng poured a basin of cold water on Qin Jingbin's head:

"But Lao Qin, what do you think Chief Master Lu means? I see that when I had an argument with Zhao Rusong, his attitude was a little intriguing, and I vaguely felt that Chief Master Lu didn't seem to be very satisfied with our composite armor, especially when he heard that we were compared with the T-72 main armor, he frowned.

In addition, I also think that he seems to be very much in favor of us and Zhao Rusong in tomorrow to have a needle-to-tip test confrontation against Maimang, if as we said on the way here, someone is red and wants to drag his feet, then the current Zhao Rusong is one, but Chief Lu's attitude is unpredictable, you say what Chief Lu means"

Zhu Haifeng's words were not finished, but his meaning was already self-evident, although Zhu Haifeng was a stubborn temper, but he was not stupid, even if he was arguing with Zhao Rusong, he still looked at Lu Jiadong's reaction as the chief designer of the new tank, but he didn't think about it because he was angry, and when he listened to Qin Jingbin's words, he faintly felt that something was wrong.

And Qin Jingbin listened to Zhu Haifeng's words, and immediately put away his happy smile, frowned and thought about it carefully, Lu Jiadong's attitude from afternoon to dinner was indeed as Zhu Haifeng said, it was a little unclear, as if there was some hidden meaning, but Qin Jingbin was relieved when he thought about it, a confident smile appeared on the corner of his mouth again, and patted Zhu Haifeng's shoulder beside him:

"Lao Zhu, you're thinking too much!"

"Thinking too much?" Zhu Haifeng looked at Qin Jingbin suspiciously, but Qin Jingbin continued with a smile on his face: "Chief Master Lu is a person who pays attention to practical results, he often says that he is doing a lot of things on his lips, it is better to come with real knives and guns, his attitude towards composite armor is unknown, is his attitude towards the new anti-tank ammunition certain?"

"This" Zhu Haifeng opened his mouth but didn't say any more, but Qin Jingbin's words didn't stop there: "So, the key is to look at tomorrow's test, as long as we show real results on the test field, Chief Lu's attitude will naturally be clear!"

After listening to Qin Jingbin's words, Zhu Haifeng pondered for a moment, and then nodded slightly

At the same time, in the room located upstairs east of Qin Jingbin and Zhu Haifeng, Wu Tianming pushed the door and walked in with a tired face, and when he saw Lu Jiadong sitting on a chair reading the newspaper leisurely, a pair of thick eyebrows couldn't help frowning lightly twice, and then asked in a deep voice:

"Jiadong, what the hell do you think?" (To be continued.) )
