Rebirth of the 1980s: The Military Industry Empire

Capital, Institute 201.

Originally, Qin Yang and the others planned to go to the 617 Factory on the grasslands and make a big splash, but after only three days, Old Zhu and Qin Yang returned. Of course, Lu Feng had to return with Qin Yang as well. Recruiting such technical personnel had to be done decisively to avoid complications.

However, he couldn't focus on researching welding rods for the time being, as a large group of experts and commanders from the armored forces were still waiting for him.

"Everyone, look at the structural diagram of this under-mirror fire control system. The sighting telescope is mounted on the top of the turret and connected to the gun through a four-bar linkage, moving with the main gun. Other optical components also move with the main gun, except for this 120-degree isosceles prism. This prism is mounted on the outer frame of a two-degree-of-freedom gyroscope to achieve independent attitude stabilization, unaffected by the rotation of the mirror body."

"Simply put, the over-mirror system relies on stabilizing the upper reflecting mirror to achieve a stable field of view for the sighting telescope, while the under-mirror system relies on stabilizing the lower reflecting mirror," Qin Yang introduced the optical path of the fire control system to everyone, and then began to summarize.

"The former stabilizes the entire upper reflecting mirror through a gyroscope group and servo mechanism. Photoelectric components such as night vision devices, laser rangefinders, and white-light telescope groups are all installed below this shared upper reflecting mirror, sharing a stable field of view. Our under-mirror system uses a gyroscope to directly stabilize the 120-degree prism in the sighting telescope. This structure is simple, suitable for our current industrial base, and the cost is relatively low. If we rashly choose the Western over-mirror stabilization system, the technical difficulty is high, and the processing requirements are demanding. Even if it is designed, it cannot be produced."

The tank constantly bumps while moving, but the muzzle always points steadily at the target. This sounds impressive, but the principle is not difficult. It requires the cooperation of a gyroscope and a servo system. The gyroscope constantly monitors the vehicle's attitude. For example, if the vehicle tilts upwards, it sends a signal to the servo system to lower the gun barrel. If the vehicle turns left, it sends the monitored signal to the servo system to control the turret to turn right, adjusting as much as necessary to achieve muzzle stabilization.

The stabilization of the fire control system is also solved in this way. As long as the gyroscope monitors and the servo system adjusts, the image in the field of view can be stabilized. However, stabilizing the entire reflecting mirror assembly and stabilizing a single prism are completely different in terms of technical difficulty.

Theoretically, this technology is achievable, but the West has never used it. Is it feasible for us to invent such a completely new fire control system?

Even Leader Huang, who has always supported Qin Yang, did not dare to speak easily this time.

"The goal set by the armored forces for us is a first-round hit rate of no less than 65% when shooting at a moving target 1,500 meters away at a speed of 20 kilometers per hour. Now, using the fire control system I mentioned, the first-round hit rate will reach 85%. If it doesn't, I, Qin Yang, am willing to withdraw from military industrial research and development from now on!"

"Our Optical Research Laboratory is willing to fully support the research and development of this fire control system," said Wang Qiao, the head of the Optical Research Laboratory. "We will definitely help Chief Qin complete the research and development of this fire control system. If it cannot be developed, I am willing to jump off the cliff like the old stonemason who carved the Longmen Grottoes in Xishan!"

The principle was proposed by Qin Yang, but Factory 960 does not have optical research and production capabilities, so it still falls to their Optical Research Laboratory at Institute 201. After all, they are responsible for developing tank fire control systems.

The fire control system they originally planned to research was too backward to become the fire control system for third-generation tanks. Now that Chief Qin has proposed this plan, what else can they say? They must fully support it!

"Engineer Wang, you won't jump down. We will stand on the highest peak of tank fire control systems!" Qin Yang said.

"Okay, then let's go with this fire control system. Who cares about over-mirror or under-mirror, as long as it's stabilized and more advanced than what we have now!" Leader Huang decided. "Besides, the funding comes from Old Ba's research funding. Even if we fail, we can just continue to use a modified version of the 37 fire control system."

The leaders of the troops finally agreed. This is a major event in the development of domestic third-generation tanks! Once this project is successfully developed, the fire control defects of third-generation tanks will be filled!

Old Zhu had not dared to make a decision because this project was of great importance, and now, he hoped that Chief Qin could continue to write his legend.

"Chief Qin, how much time will the research and development of this fire control system take?" Old Zhu asked expectantly.

"About a week to half a month," Qin Yang said. "We can't delay the test drive. When the turret of the Type 85 tank is assembled over there, our fire control system must also be installed."

"Okay, then we'll wait. Half a month later, let's go to the grasslands together to see the Type 85 tank's target practice!" Leader Huang said.

The under-mirror fire control system seems incredible to everyone, but in the eyes of Qin Yang, a military industry expert, it is a very common thing. If he were to brag, he could draw the design drawings and assemble the fire control system with his eyes closed!

After all, from the Type 85 to the Type 88, and then to the Type 96, domestic tanks all used under-mirror fire control systems. The Type 99 tank also used under-mirror fire control first, and only switched to over-mirror fire control on the Type 99A. Not to mention him, the tank soldiers on the front line dared to disassemble and repair it.

After the meeting, Wang Qiao looked expectant: "Chief Qin, everyone in our research laboratory will listen to your command. What calculation work do we need to do? If necessary, we can borrow a hand-cranked computer."

"No need for that either."

"What preparations do we need to make?"

"No need for that either. Next, I will draw some dimensions and parameters of the lenses, and you will go to the optical instrument factory and supervise their processing."

What?

Process it directly?

This is a brand-new research and development of a fire control system. We need to calculate various data first, then experiment, determine the specific values through experiments, and then proceed to the processing stage. This is like getting glasses. You always have to try different lenses with those thick-framed glasses.

Chief Qin is actually going to process it directly?

He was stunned.

"By the way, we also need gyroscopes, specialized frames, and shell processing. I'll coordinate these. Let's try to complete the production of these parts in three days, and then assemble them in one day. We can get it done in four or five days."

What? It'll be done in four or five days?

"Chief Qin, didn't you say a week to half a month at the meeting just now?"

"I was afraid of scaring them if I said it," Qin Yang smiled.

Under his repeated miracles, no one dares to jump out and make trouble for him now, so there is no need for him to pretend to be cool. It's better to do research honestly.

While speaking, the group came to the research room. Qin Yang picked up the drawing tools and started drawing directly on the drawing board.

"Come, this pentagonal prism is already drawn. Take it for processing immediately!"

"Come, this is a convex lens and a concave lens."

"This is a 45-degree prism…"

While Qin Yang was busy with the tank fire control system, Zhang Chao also took Lu Feng to the factory and enthusiastically arranged accommodation for him.

Continuing to release structural diagrams, this is the great invention and creation of our country.
