Rebirth of the 1980s: The Military Industry Empire

201 Institute.

"Advanced turbochargers easily reach tens of thousands of revolutions per minute, requiring fully floating bearings lubricated by engine oil. For us, developing advanced turbocharger bearings is a significant challenge," Zhang Baozhong said.

Zhang Baozhong came to find Old Zhu, but before seeing him, he met Qin Yang and started discussing these technologies with him.

In reality, squeezing power is simple. With the same displacement, strengthen components like piston rods, then increase air intake and fuel injection. The former requires high-performance turbochargers, and the latter requires high-performance fuel injection pumps. These both heavily test materials and processing levels.

"If our diesel engine industry doesn't have it, we can look to the aircraft industry. Aircraft engines often reach tens of thousands of revolutions per minute, so their bearings must be able to withstand it," Qin Yang said.

Zhang Baozhong's eyes lit up. That's right, how did he not think of this shortcut? Engineer Qin is indeed quick-witted.

"Tomorrow, I'll go to our domestic aero-engine factory to take a look," Zhang Baozhong said.

Just then, Old Zhu walked in from outside: "Oh, you two are already chatting? Engineer Qin, I just received a message from the national proving ground. Would you like to hear it?"

Qin Yang shook his head: "No, it's more trouble if I hear it."

Zhang Baozhong glanced at the two of them. Something's up, definitely something's up! His gossipy nature kicked in: "Old Zhu, tell us, what's the news?"

"Factory 9123 has trial-produced extended-range shells. The appearance is exactly the same as the one test-fired by Factory 960, but they haven't mastered the production process, and there was a big problem during the test firing," Old Zhu said, regardless of whether Qin Yang wanted to hear it or not, because he was also very curious: "Besides the jujube-shaped appearance being different from our existing ones, these shells have four more protrusions. These four protrusions stumped Factory 9123. They tried many methods and finally decided to fix them with screws. During the test firing, the protrusions would fall off as the shell flew out, causing the missile to tumble forward, with a range of only four or five kilometers. They removed the protrusions, and the shell could fly farther than before, but the accuracy was ridiculously bad, with a lateral error of eight hundred meters!"

Although Zhang Baozhong builds engines, he still knows a little about artillery. Hearing Old Zhu say this, he was immediately surprised: "These four small protrusions are so magical?"

"That's right, Engineer Qin, tell us what's going on?" Old Zhu looked at Qin Yang, his eyes full of anticipation.

What's going on? It's just a repeat of history. Qin Yang could guess eight or nine out of ten even without listening.

When the jujube-shaped shell was introduced, the domestic welding technology was not up to par and could not weld the four centering parts onto the shell. So, they used screws. As a result, no matter how tight they were screwed, the screws would always loosen after the shell was fired, causing one or several centering parts to fly off. Once this thing fell off, the consequences were predictable.

Initially, domestic technical experts couldn't figure it out no matter what, and they had to import related welding equipment from abroad, spending a large sum of money to solve the problem. Then, after several years of research, they believed that manual arc welding was also possible, but the required technology was very high and could not be mass-produced at all. In addition, with the rapid development of domestic special welding technology, there was no need to bother with it.

Qin Yang can complete the production of a prototype shell by manual welding, which he practiced in his spare time before transmigrating, with superb skills. However, if this world wants to mass-produce it, he also has to import equipment, after all, not everyone has his kind of technology.

In addition to welding, the shape of the four protrusions is also very critical. On the surface, it seems that Qin Yang made them casually, but in fact, if the shape of this thing is slightly off, it will cause the shell to deviate during flight, let alone remove them all. It simply won't be accurate.

To put it more clearly, mass production of this thing requires numerically controlled machine tools to control the accuracy. When China introduced the 155mm gun in later generations, it cost a huge amount of money to modify a 152mm shell production line in order to produce shells.

Qin Yang's manual grinding looks very rough, but it is actually the accumulation of his experience in later generations. No one in this world can do it.

The jujube-shaped shell is not something that everyone can handle. Whoever wants to copy it will be miserably pitted.

Now, Old Zhu can't wait to know the answer. Qin Yang has nothing to hide from Old Zhu: "Old Zhu, this kind of shell can either be precision-machined by me alone, probably one or two a day, or it can be precision-machined with numerically controlled machine tools and laser welding equipment. I'm not underestimating Factory 9123, but none of the batch of shells they produced are qualified. They are all waste products."

"So that's what's going on." Old Zhu nodded: "However, you have to be mentally prepared. After the news came, Factory 9123 has already produced 814 shells and purchased a large number of production raw materials. The bank's first loan of two million and the three hundred and fifty thousand voluntarily raised by their workers have all been spent. Part of the second loan of five million has also been spent to purchase raw materials. Now, their factory has no way out. Higher-level leaders may ask you to help."

"Me? Of course I will help. I can buy those shells they produced at twice the price of scrap iron," Qin Yang said.

Old Zhu shook his head with a wry smile: "I'm afraid that won't work. Higher-level leaders may ask you to find a way to revive Factory 9123."

"That's absolutely impossible. If Factory 9123 goes under, I can buy back their production equipment. That's a small favor for them."

Just then, the office phone rang. Because it was next to Qin Yang, he grabbed it.

"Director Qin, you're here?"

"Yes, Director Fang, what can I do for you? I'm busy with Engineer Zhang and the others in a meeting researching tank engines!"

"I heard something today." Director Fang said: "Our Chaoyang District Police Station recently transferred in a new police officer. He hasn't been here long, but he's caught all the nearby thieves. Do you know how he did it?"

"I don't know."

"He goes out in plain clothes and deliberately leaves half of his wallet sticking out. When a thief tries to steal it, he can use their trick against them and catch the thief. What do you say, isn't our police officer very capable?"

What? Entrapment? Is this implying that I deliberately set a trap?
