Rebirth of the 1980s: The Military Industry Empire

201 Institute, family compound.

“Engineer Qin, why don't you just stay at my place for tonight? Tomorrow, we still need to continue the meeting. After the meeting tomorrow, you can leave.” Old Zhu chuckled as he led Qin Yang back to his home.

“Actually, I can stay at the guest house. Old Zhu, you're really too kind.” Qin Yang was somewhat helpless. The conditions at the guest house were much better, but Old Zhu insisted. What could he do? He also knew that Old Zhu's purpose was to chat with him.

A large group of people went to stay at the guest house, but Old Zhu just wouldn't let Qin Yang go, insisting that Qin Yang stay at his place.

“Seeing how Old Huang demanded a bidding process for the tank gun today, you didn't seem worried at all, full of confidence.” Old Zhu said.

“Of course. Old Zhu, you were also full of confidence, right? You didn't say a single good word for me because you knew I would definitely win.” Qin Yang said.

“That's right. Even if a brand new 120mm gun is created with new technology, some of its inherent flaws will still exist.” Old Zhu said, “Considering the height of us Easterners, the loader's strength is limited. Even with a 120mm shell, an automatic loader is necessary. Not to mention that Old Zhuang used a large combustion chamber to increase the power of the tank gun, those shells are too heavy and impossible to load manually. However, we don't have mature bustle-mounted autoloaders for us to study, so this kind of gun is destined not to be recognized by the military.”

As Old Zhu spoke, he and Qin Yang made the bed together. At this moment, he looked up at Qin Yang, “Engineer Qin, would you say I'm right?”

“You're only partly right.” Qin Yang said, “The loading issue is only one aspect. They also want to increase the length of the barrel, which makes manufacturing even more difficult. Of course, the most important issue is the shell. I'm confident that I can manufacture more advanced shells that, when loaded into a 125mm gun, can achieve greater penetration.”

The longer the barrel, the more difficult the manufacturing. Therefore, ordinary tank guns will not exceed 50 calibers. If Factory 447 wants to increase the penetration of the 120mm tank gun, they have to lengthen the barrel. Even if they are specialized in making guns, they will face countless problems!

Compared to lengthening, thickening is easier to achieve. This is the advantage of the 125mm tank gun. He can provide the most powerful and affordable tank gun. What can Factory 447 compare with him?

Moreover, the gun is important, but the shell is even more important! With the same gun, more advanced shells can be developed to achieve better penetration. When it comes to making armor-piercing projectiles, Qin Yang is definitely a professional.

As for the brother factory's 120mm gun, Qin Yang has no reason to develop it for them. Anyway, he knows that this gun has already been abandoned in history. After failing to win the bid for the third-generation tank gun, Factory 447 installed it on a self-propelled chassis and turned it into the Type 89 tank destroyer, which was also called the "Eastern Ferdinand." However, no matter how it is embellished, this gun is like a shooting star, quickly disappearing from the military's weapons and equipment.

In Qin Yang's view, this is a waste. Just develop the 125mm tank gun directly, there is no need to continue wasting time on the 120mm gun. What bidding? His plan is already the best.

“You're right.” Old Zhu nodded, “I really don't know how you came up with it, always able to come up with leading things. You make our entire 201 Institute feel ashamed. By the way, were you digging a hole for Old Ni with those words you said at the dinner table today?”

“How is that possible? Old Zhu, don't wrong me. Our Factory 960 doesn't have the ability for the engine project, so there's no need to get involved. Whether it's the X150 or the 150HB, it will definitely be produced at Factory 616 in the end.”

“150HB? What is that?” Old Zhu asked curiously.

Qin Yang felt embarrassed. He had let it slip. It wouldn't be called 150HB until the project was finalized. It doesn't have that model number yet.

“Nothing, sleep, sleep.” Qin Yang got into bed and then snored.

This night, many people were destined to be sleepless.

Director Ni tossed and turned, Qin Yang's words constantly appearing in his mind.

A 1,200-horsepower engine is just a transition. Next, they need 1,500 horsepower, or even more!

Can the foundation of the old Soviet diesel engine be improved to that extent? Of course not! The cylinder spacing is too small, the heat dissipation problem cannot be solved, and the blown head gasket is a sure thing!

The next day, Director Ni came to the meeting room with dark circles under his eyes. When everyone saw him, they were stunned.

“Old Ni, didn't you sleep well yesterday?”

“No, please let Engineer Zhang introduce their plan first.”

Zhang Baozhong also didn't sleep. After returning yesterday, they immediately refined their plan, almost working hard all night. However, they are still full of energy now.

“Leaders, we plan to name this engine 150HB. It is a large-displacement, medium-speed, medium-effective-pressure engine. We still retain the original 150mm diameter cylinder. In order to solve the heat dissipation problem while minimizing the volume as much as possible, we decided to increase the cylinder spacing to 184mm. In this way, the length of the entire engine can be controlled within one and a half meters.”

The cylinder spacing is the distance between the centers of the two cylinders, that is, how close the two cylinders are. German engines have high speeds and high heat, so they use a large cylinder spacing. The cylinder spacing of the contemporary MB873 is 224mm, and the cylinder spacing of the MT883 is 195mm. It can be seen that even if it is improved compared to the previous engine, it is still not comparable to the Leopard 2 engine.

Of course, this is also to reduce the size of the engine. The Leopard 2 engine is 1970mm long and 1703mm wide, which is a nearly square behemoth, resulting in the tank having a big butt.

Since we are going to take the Soviet route, of course we can't make it too big.

“The West has increased the average effective pressure to 2 MPa, which greatly increases the power of the engine, but considering our technological breakthroughs in high-pressure oil pumps and turbochargers, we still decided to set the indicator at about 1.5 MPa, which is easier to achieve.”

Zhang Baozhong said the specific data of the engine one by one, so that everyone can evaluate it. After he introduced it in detail and answered many people's questions, an hour passed.

“Next, please let the comrades from our Factory 616 talk about their plan.” Old Huang continued.

Guo Liming was just about to stand up when he saw Director Ni stand up with a swish, clenching his fists, his face flushed.

What is he going to do? Guo Liming was very curious.

“Leaders, our Factory 616 has decided to support the engine institute's design plan. We will give full play to the advantages of combining the factory and the institute, and strive to develop this 150HB diesel engine!”

What? Everyone was surprised.

Everything was within Qin Yang's expectations. He murmured in a low voice: “Director Ni is afraid that he will be criticized for a while for selling out the factory for personal gain.”
