On the podium, Lu Jiadong, the chief designer of the new tank, was explaining various tank-related technical theories as usual, and the tank development team members sitting below were frequently interacting with the young chief engineer, and in the face of various problems, Lu Jiadong also knew everything and said everything.

It's just that Zhao Chenggang, who was sitting in the corner of the third row, couldn't hear anything, because his head was already a mess at this time, and the buzzing tinnitus made him look like a silent puppet show, lifeless, and his whole person was even more so, so that when he sat down, Liu Xueyong, the head of the technical section of the Yunnan Special Vehicle Factory next to him, pressed him like a puppet.

But even so, Zhao Chenggang was still stunned, because he regretted it very much, why did he have to make trouble for himself for a false dream, if he was facing a person with a slightly worse technical level, it would be fine, but it was indeed Lu Jiadong, who had quite comprehensive military technology.

What I just said, whether it is depth or breadth, or specific technical data, we can see the efforts of the young Chief Lu on the suspension system, and the specific data, the mechanical structure, the mature and reliable manufacturing process and the unattainable vision make Zhao Chenggang difficult to match.

And he just got an axe in front of such a person, isn't this just taking the initiative to stretch his face over and make people snap and beat, at this moment he really hopes that Lu Jiadong can point at him and scold him straight, or have a dark belly, and stab him in the back without saying anything to his face, after all, in this way, it shows that his theory is correct from another side, even if he is scolded, being hacked cannot change the technical truth and correctness.

However, Lu Jiadong did not scold. Not to mention black, but to use more sophisticated technical knowledge to refute it, so that he has nothing to say, not to mention that in the face of the entire new tank development team, now that he thinks about it, he is too obsessed with that unrealistic dream, if he can see it a little, maybe it won't be so. However, there is no if, let alone regret medicine in this world, since the bitter fruit is planted by yourself, you can only pinch your nose and swallow it

"Xiao Zhao, Xiao Zhao, Xiao Zhao" I don't know how long it took, Zhao Chenggang's ears faintly heard the call of Liu Xueyong beside him, and then his body also felt that he was constantly shaking, until this time Zhao Chenggang slowly woke up from his stunned state. And Liu Xueyong, who was sitting next to him, saw that Zhao Cheng had just come back to his senses, so he angrily scolded the podium:

"What are you thinking?

"I" didn't wait for Liu Xueyong to finish speaking, Zhao Chenggang moved his lips slightly, but after brewing for a long time, only such a word came out, and then he lowered his head in embarrassment, Liu Xueyong couldn't help patting Zhao Chenggang's shoulder when he saw this:

"If you don't understand, you can learn it with an open mind, and if you understand, you can become proficient a little bit, and the high technical level of Master Lu is also accumulated bit by bit. Your little setback is not to be seen, how can you improve in the future?"

"Section chief. I"

"Okay, wait for two days for Director Guo to come over, let him talk to Chief Master Lu, presumably with Chief Master Lu's broad mind will not take it to heart, now you hurry up and listen carefully, is talking about the key materials and processes of the torsion bar spring suspension system. This is a rare opportunity!"

Listening to Liu Xueyong's comfort, Zhao Chenggang's depressed mood suddenly improved a lot, and Lu Jiadong's calm and powerful words on the podium also clearly reached his ears:

"The torsion bar spring suspension requires a metal rod, which is obviously not possible according to the torsion bar process on the Type 59 tank, and perhaps we didn't have a way more than a year ago. But now we have many ways to strengthen the billet, such as electroslag remelting, for example, vacuum arc remelting, all of which are ways to strengthen the billet in the smelting stage!"

"Do we have such a process?" asked a member of the tank development team sitting in the front row, and Lu Jiadong couldn't help but smile at him when he heard this:

"Then we have to ask our Shonan Special Steel Factory, you must know that the cannon steel of the 52 times caliber 155mm howitzer that has just been installed in the army is produced by them, and the smelting technology applied is electroslag remelting!"

As soon as Lu Jiadong's voice fell, everyone's eyes all turned to a few technicians from the South Hunan Special Steel Plant in the middle and back, seeing that they all nodded slightly, everyone suddenly heard a whisper, and Zhao Chenggang, who was sitting in the corner of the third row, couldn't help but be stunned, and then seemed to have figured out something, but there was a feeling that he could not break through through a layer of window paper, just when he was seeking progress for this, Lu Jiadong's words sounded in his ears again:

"In the heat treatment, the previous medium temperature tempering is changed to low temperature tempering, so that the torsional yield of the finished product is improved while maintaining the good toughness and plasticity of the billet.

The cannon steel of the 52 times 155mm gun just mentioned is also inseparable from the electroslag remelting process, such a large output and the application of mature technology, the cost required will naturally decrease, as for the torsion bar billet processing technology is not difficult, just increase the shot peening or rolling surface mechanical strengthening treatment and strong torsional prestress to improve the bearing capacity of the torsion bar spring, and the improved torsion bar spring can become a high-strength torsion bar spring. ”

After listening to Lu Jiadong's words, the people present suddenly realized that the joints that used the torsion bar spring suspension system were actually here, but they did not expect Lu Jiadong to apply the smelting and processing process of manufacturing high-strength cannon steel to the suspension system, and the chamber pressure of the gun was hundreds of gigapascals, and the vibration pressure of the load wheel of the tank and the ground may not even be a fraction of it.

Therefore, the reliability of the steel torsion bar using the gun steel process technology can be imagined, and because this process has been perfected and matured in the development and production process of the new howitzer, coupled with the tank gun steel should also be applied to this technology, the price of the unit will inevitably be diluted in the case of capacity expansion, so the cost will not be too high.

Because of this, everyone present praised Lu Jiadong's method, and their admiration for Lu Jiadong deepened a little, and the same was true for Zhao Chenggang in the corner of the third row, in fact, he happened to be unable to break through through a layer of window paper is what Lu Jiadong just said.

When Lu Jiadong mentioned the new howitzer, Zhao Chenggang also thought of this, but the layer of window paper was not pierced, and now it was explained by Lu Jiadong, Zhao Chenggang's heart was also suddenly enlightened, and he suddenly felt that the torsion bar spring suspension system was indeed a good choice for the new tank, and at the same time, he also admired Lu Jiadong's broad vision, comprehensive technology, and profound knowledge.

However, although Zhao Chenggang has completely accepted the torsion bar spring suspension system and no longer insists on the liquid gas suspension system, he still has a little regret in his heart, and finally sighs secretly:

"It seems that the liquid-pneumatic suspension system is still too advanced!"

As soon as the words fell, Zhao Chenggang couldn't help but shake his head self-deprecatingly, then raised his head and listened carefully to Lu Jiadong's explanation again: "An electroslag remelting technology can produce all the blanks of howitzers, tank guns and torsion bar suspensions, which is the benefit of technology extension, in fact, we can find many examples of this on our new tanks."

For example, the ballistic computer of the fire control system is improved by applying the ballistic computer of the artillery radar, and the infrared night vision equipment is borrowed from the technology of the observation and sighting equipment of the submarine.

Zhao Chenggang, who had already calmed down, carefully memorized every word Lu Jiadong said in his notebook, but when he was struggling to write, his pen suddenly stopped, because Lu Jiadong's next words made his flame of hope burn again:

"Take the liquid-gas suspension system proposed by Comrade Zhao Chenggang of the Yunnan South Plant just now, although a front-line combat vehicle similar to a tank is not suitable for a similar suspension system due to factors such as safety, reliability, and maintenance, it is an extremely practical technology as a self-propelled gun.

It is necessary to know that the self-propelled gun with the liquid-gas suspension system can adjust the pitch of the vehicle body, supplement the high and low firing angles of the artillery, and expand the fire attack range of the artillery.

As soon as Lu Jiadong's words fell, Zhao Chenggang stood up from his seat with irrepressible excitement on his face, and asked excitedly:

"Can Chief Lulu really achieve it?"

Lu Jiadong looked at Zhao Chenggang, still with an indifferent smile on his face: "Before you introduced the liquid gas suspension system you designed just now, didn't I say that this technology will be of great use in the future!"

"Ah" Zhao Chenggang couldn't think of it for a while while he was excited, and Liu Xueyong, who was beside him, nodded: "That's right, Xiao Zhao, Chief Lu really said that!" After speaking, Liu Xueyong turned to Zhao Chenggang and said reproachfully: "You, why do you still think so much, it's better to do the things in front of you well than anything else, self-propelled artillery or something, that's still a shadowless thing."

"How can it be a shadowless thing?" Before Liu Xueyong could finish speaking, Lu Jiadong took his words: "Since tanks can be developed, will self-propelled artillery be far away? These two are indispensable weapons for mechanized troops!"

"Chief Master Lu, do we also want to develop self-propelled artillery?" Zhao Chenggang's eyes flashed with dazzling brilliance, while Lu Jiadong said with a brighter smile and confidence:

"Anything is possible!" (To be continued......)
