Courtyard Houses: The Great Masters of a Nation Hidden Within

Gao Jianguo lay on the paper, drawing as he explained to Lin Jianguo.

"Do you still remember the thermodynamic cycle of gases?"

Lin Jianguo nodded quickly, "I remember, I remember, how could I forget?"

Gao Jianguo pointed to the diagram he had just drawn, "You know that compressed gas absorbs a lot of heat when it expands."

Lin Jianguo thought hard for a moment, "Ah, right, right, how does your brain work, haha."

Gao Jianguo grabbed another piece of paper, poked the diagram with the tip of his pen, and continued talking.

"This heat-absorbing force, combined with suitable heat exchange devices, can pull the object being cooled down to tens of degrees below zero in one go."

"If you choose a suitable expansion rate and design a reasonable expansion chamber, you should be able to produce what you need."

Lin Jianguo grabbed Gao Jianguo's shoulders and shook him violently, "Old Gao, that's great, that's great! We've found the direction! You're a genius!"

A genius? Gao Jianguo knew in his heart that he wasn't.

To put it simply, this technology is the same thing that was later used on the Raiden 2B infrared air-to-air missile, which significantly improved the detection sensitivity of the infrared seeker.

The second-generation infrared seekers like the AIM-9D from Qiguo all follow this path.

Gao Jianguo knew exactly what the third-generation infrared seeker used, but he couldn't say it directly right now.

You can't just pat Lin Jianguo on the shoulder and say, "Jianguo, you guys should work on indium antimonide"—that would put him in big trouble.

Now that we know that this is what Lin Jianguo is doing, let's find an opportunity to slowly steer him away from it later.

The second diagram was also finished. He didn't know what the compressed gas refrigeration device of the Thunder 2B looked like, but back when he was a military enthusiast, the structure of the vortex tube refrigeration device with the same principle was already engraved in his mind.

Let's just draw it out and see if Lin Jianguo and the others can use it.

"Here, take a look. I figured this out myself. See if it's of any use to you guys?"

Lin Jianguo looked at the simple structural diagram with eyes glued to it, as if he had found a treasure, and kept exclaiming in admiration.

Gao Jianguo stretched out his finger to explain the structure in the diagram, but Lin Jianguo shoved his hand aside.

"Where are you rubbing your hands? Don't smudge my precious picture."

Gao Jianguo chuckled to himself. Lin Jianguo's appearance reminded him of the joke that went viral online in his past life about a wealthy dog ​​buying a warship.

"Young hero, here is your money. Now please disembark from my boat."

Lin Jianguo thought about it for a moment and found it funny too, and the two of them burst into laughter.

After laughing for a few moments, Lin Jianguo straightened his expression and gripped Gao Jianguo's hand tightly.

"Comrade Jianguo, thank you so much! Your approach has truly solved a major problem for us."

He came to see Gao Jianguo today without much hope, just to try his luck and broaden his horizons.

I never expected such a big surprise to fall into my lap.

Gao Jianguo also composed himself. "Comrade Jianguo, you're too kind. This is what I should do. I will do my best within my power."

Lin Jianguo carefully picked up the two thin pieces of paper, gently blew the ink off them, and carefully tucked them into his pocket.

"Jianguo, I won't say much more, hehe, if it yields results, your name will definitely be on the list. Your path is extremely important."

"I'm going back right now. With something like this, I'm really itching to get it working out with my colleagues."

Gao Jianguo understood that feeling; it was the creative drive inherent in the bones of scientific researchers.

However, seeing how much he treasured it, and considering his workplace, Gao Jianguo thought for a moment and asked, "Jianguo, should I send two militiamen to escort you back to your unit?"

Lin Jianguo was taken aback. "Militia comrade? You can still mobilize the militia?"

Gao Jianguo chuckled and patted his chest, "Deputy Chief of the Training Section of the Security Department, Deputy Captain of the Militia Team, hahaha."

He was quite casual in front of his old classmates; there was nothing he couldn't talk about.

Lin Jianguo was momentarily speechless. "Ah... this, this... I knew you came from the battlefield, but I didn't expect you to have retained your skills even after returning."

He gave Gao Jianguo a thumbs-up, thought for a moment, and said, "Then I'll trouble you two militia comrades to give me a ride. I really do have a bit..."

Gao Jianguo understood perfectly, patted him on the shoulder, and led him to the militiamen on duty.

He briefly explained the situation to Section Chief Wang, and then selected two reliable militiamen to escort Lin Jianguo back to his unit.

As soon as Lin Jianguo stepped into the office, he excitedly headed straight for the guidance subsystem.

"Engineer Zhao, I've brought back some good stuff!"

Zhao Gongzheng was discussing matters with Chief Designer Sun, who was involved in missile replication, when they saw Lin Jianguo enter and stopped talking.

The reason Lin Jianguo was so happy was definitely not because he carried two bags of rice.

"Oh? What good stuff does your classmate have?" Engineer Zhao knew where he had gone; during working hours, Lin Jianguo had nowhere else to go.

"Look!" Lin Jianguo pulled out two sheets of paper from Gao Jianguo and began to discuss Gao Jianguo's ideas and plans with the two bigwigs.

As Lin Jianguo continued speaking, the two bigwigs' eyes lit up, and they kept praising him.

Before Zhao could even utter a sound after he finished speaking, Chief Engineer Sun slammed his hand on the table.

"Great! Let's do it this way! Where did you go? You brought back these two precious things."

Engineer Zhao picked up the conversation, "This approach is indeed ingenious; it covers all our requirements, and the cost is low."

"He went to the third steel rolling mill today. He has a classmate there, and he figured that since the steel rolling mill is in a high-temperature environment all day, he should have some ideas about cooling and refrigeration."

"I never expected this, it's not as simple as just having a few ideas."

Lin Jianguo quickly added, "Jianguo said that our requirements and their factory's needs are completely different things. This is a different method he came up with for me."

"From the moment I finished stating my request to the moment he pulled out this method, the pause was less than five seconds. It was incredibly impressive."

The name "Jianguo" caught the attention of both Engineer Zhao and Chief Engineer Sun.

"Third Rolling Mill," "Jianguo," the two glanced at each other, but didn't respond for the moment.

Chief Engineer Sun immediately set the direction, saying, "Old Zhao, Xiao Lin, I think this comrade's idea is excellent. You two should just follow his line of thought and get started."

Engineer Zhao agreed immediately and turned to tell Lin Jianguo to gather people and start the experiment according to Gao Jianguo's idea.

After Lin Jianguo received his assignment and left, Chief Engineer Sun and Engineer Zhao exchanged another glance.

Chief Engineer Sun tapped his finger on the table. "Gao Jianguo? Do you remember the internal bulletin from the 17th Ministry of Machine Building that we just received? About that new high-temperature alloy material?"

Engineer Zhao nodded. "I was just thinking about this too. The 3Z-591, the one we plan to use on the casing of a missile's solid-fuel engine."

"I remember the announcement clearly stated that the person who produced this material was named Gao Jianguo."
