Chapter 266 Air Rudder Gyro Rudder and Gas Rudder
Gao Zhendong had no idea what was happening far away. He and Yu Yuncheng were currently receiving the batch of graphite components that Duan Gong had mentioned a few days ago.

Now everything is ready for the single crystal furnace to officially pull the target silicon crystal, except for the east wind.

This Dongfeng refers to this batch of graphite components from the Carbon Research Institute, which will be used to replace and supplement some graphite components of the single crystal furnace.

After the two verified and counted the graphite components, they found no problems.

As Yu Yuncheng and Gao Zhendong signed the handover documents together, he said happily: "Director Gao, we will replace the graphite components as quickly as possible and make final preparations such as baking the new components. We estimate that we can start the formal test on Saturday."

Gao Zhendong was also very excited, but he still reminded him: "Pay attention to the test system and related requirements. Don't be impatient. You have already had a lot of time. Don't let the last bit of time get in the way."

Yu Yuncheng naturally knew this truth: "Well, I will pay attention to it and have taken these factors into consideration."

He is also an experienced researcher. Gao Zhendong mentioned this matter mainly for the sake of being on the safe side.

Gao Zhendong returned to his office with the tungsten-molybdenum alloy throat liner with graphite backing sent back by the Carbon Research Institute, including the test pieces after the test and the extra new pieces.

In addition to these, there was also a package sent by Duan Gong along with the components. Although he didn't know Gao Zhendong was married when he sent the package, he still sent some things as usual according to his habit.

This old man is very careful when he needs to be careful.

It’s true, the weight of these things added together is quite heavy. If Gao Zhendong wasn’t very strong, he really wouldn’t be able to move them away.

After unpacking the package sent by Duan Gong, we found that it mainly contained food ingredients, including pickled products and dried products. It's not that Duan Gong has no originality in sending gifts, but these things are the most practical these days, and everything else is nonsense.

After keeping some strange and weird things for himself, Gao Zhendong packed the most solid ones, such as large pieces of dried meat, into a bag and sent it to Lao Chen.

At this time, material supply has gradually begun to have an impact on people of Lao Chen's level. Fortunately, the overall situation is not as serious as I heard in the previous life.

Mr. Chen looked at the package Gao Zhendong brought over and said with a smile, "Are you going to sugarcoat it for me?"

Gao Zhendong put the things in his cabinet and said, "It's not that I should honor my master. It's not that. It's just sugar coating, no bullets, haha."

Old Chen also knew Gao Zhendong's thoughts and was very pleased with his filial piety. When he wrote to his son who was working far away, he would often write: "Junior brother is very filial. With him here, you can work far away, don't miss the two elders at home."

Back in his office, Gao Zhendong looked at the remaining few new tungsten-molybdenum alloy throat liners and remembered something, so he called his classmate Lin Lianwei from the Institute of Advanced Technology.

It took a lot of effort to make this call. After all, Lin Lianwei was not like Gao Zhendong, who had a phone in his office. It took a while to get in touch with him.

Lin Lianwei still had that slightly frivolous tone: "Haha, Lao Gao, is there any good news?"

He knew that Gao Zhendong would not call him unless it was important. Chatting on the phone for a long time was not popular these days.

Gao Zhendong was also infected by his tone: "Yes, there is good news. Come over as soon as possible. I have something new for you."

Gao Zhendong took the initiative to say that he had something new? Lin Lianwei heard it and said without hesitation: "Okay, I'll come right over."

After hanging up the phone, he immediately ran to Engineer Lu to ask for leave: "Engineer Lu, our hospital's senior consultant wants to see me for something. I'm asking for leave and going over there."

"Senior Consultant?" Mr. Lu was a little confused by the formal title in his words.

"Gao Zhendong, my classmate."

"Hey, why don't you just talk about Director Gao? Why are you so pretentious? Just go ahead."

Gao Zhendong took the initiative to find Lin Lianwei, and Lin Lianwei came to ask for leave in a serious manner, so there must be some official business, and it was probably good news.

It was already afternoon when Lin Lianwei arrived at Gao Zhendong's office.

Gao Zhendong took out the remaining few new tungsten-molybdenum alloy throat liners and the test report: "Here, let's see if you can use them. If you can, go back and ask your hospital to file a report and go through the formalities to ask us for them."

It was not possible to take him away directly. Gao Zhendong himself was fine, but Lin Lianwei was trapped.

Lin Lianwei weighed the throat lining, then took the test report and started reading it.

Although he majored in automation, he was exposed to a lot of things at the Institute of Automation and was considered to be working in multiple industries. He had some understanding of engines and had asked Gao Zhendong related questions before.

So he could roughly understand the test report Gao Zhendong gave him and what kind of material it represented.

"Zhendong, is this test report of yours real?" "How fresh! I made a fake report just to tease you, right?"

Lin Lianwei also knew that what he said was a bit unreliable, so he touched his head and chuckled.

"Zhendong, can I take this report away?" He could understand the parameter characteristics, but he was undoubtedly not as proficient as the hair growth specialists in the significance and changes that the parameter characteristics could bring about. So his idea was simple: I will take the information away and show it to the professionals.

"No." Gao Zhendong's answer was concise and powerful. Lin Lianwei's face drooped suddenly. I can't take her away. Are you kidding me? My eyes are not cameras.

Gao Zhendong, who had successfully played a trick on the victim, laughed out loud: "Haha, but you can make a copy. There are only a few copies of this original document. What will I use it for if you take it away?"

Lin Lianwei then became happy. He didn't bother to chat with Gao Zhendong anymore and took out a pen and paper to start copying.

While copying, Lin Lianwei complained: "This time, I am sharing the task with the engine guys. We can't use this thing in guidance, but I have to copy for them."

Gao Zhendong said with a smile: "Shut up, besides, you may not be able to use it."

The test report was not long, but not short either, especially since it included the original test data processing, analysis, charts, etc., which made Lin Lianwei copy a lot.

Because he had to make sure it was consistent with the original, numbers and text were easy, but charts and graphs were much more difficult. Although as a top student at China Europe International Business School, Lin Lianwei had good drawing skills, he could not cope with the large number of them.

The data processing and analysis by the Carbon Research Institute is very detailed, and the most intuitive result is the many graphs.

After finally finishing copying, Lin Lianwei said goodbye and turned to run away.

Gao Zhendong was puzzled: "Why are you running? It's only an hour before we get off work. Why don't you take a rest here? I'll treat you to a meal after get off work. You can leave after dinner."

Lin Lianwei picked up the copy of the test report in his hand and raised it: "Eat shit, it's more important to solve your problem first. I want to send it back to the hospital as soon as possible."

When it comes to important matters, Lin Lianwei is still reliable. He didn't even bother to eat. He immediately said goodbye to Gao Zhendong and returned to his own courtyard.

He pedaled his bike so fast that when he returned to the yard, it was not even time to get off work.

He put the report in front of Engineer Lu and said, "Engineer Lu, Zhendong does have some good stuff. I brought the report back. You can take a look. However, it seems that this stuff is mainly used for hair growth. It has no use for us." There was a lot of regret in his words.

They are making guidance systems. This thing looks temperature and pressure resistant, so isn't it purely for hair growth?

Engineer Lu did not comment, but picked up the report and read it carefully.

After reading it for a while, he took the report and knocked on Lin Lianwei's head: "You are so ignorant, who said we can't use it?"

Lin Lianwei covered his head and said, "What can we do with this thing?"

Engineer Lu smiled and said, "The gas rudder! Although the one we copied now cannot be used for the time being, it is hard to say what will happen in the future."

Although the gas rudder appears to be installed in the tail nozzle or behind the butt, it is not actually a component of the engine. It will affect the design of the engine. After all, it is installed where the airflow is ejected. However, from the perspective of system composition, this thing is part of the guidance system.

Lin Lianwei: "What is a gas rudder?"

This is not because Lin Lianwei is uneducated, but because he has never come into contact with this thing. The prototype of the air-to-air missile they imitated, the AIM-9B "Sidewinder", does not have gas rudders. Its directional control mainly depends on the canard in front of the missile body, which is actually a set of air rudders.

There is also a set of gyro rudders on the huge tail wing of the Sidewinder, but that thing is responsible for the roll control of the missile body. During the flight of the missile, the airflow blows the gyro to rotate, and the precession effect of the gyro rotation generates a torque to suppress the roll of the missile and maintain stability.

The wonderful thing about this thing is that its rotation speed changes automatically according to the missile's flight speed. Within the missile's speed range, it can effectively suppress the missile's roll. It utilizes pure aerodynamics and mechanical principles and has no connection with the missile's guidance system at all.

However, this seemingly simple gyro rudder, which is not connected to the guidance system, can suppress the missile's roll during flight and allow the missile to adapt to larger G values. In simple terms, it has better maneuverability and faster turns.

Engineer Lu explained the principle of the gas rudder to Lin Lianwei, who was stunned. After all, he was from the field of automation, not missile design, so it was normal that he did not understand the gas rudder for the time being.

To use a lofty concept from Gao Zhendong's previous life, the gas rudder is actually a means of thrust vector control.

The deflection of the rudder body in the high-speed gas flow is used to generate control torque. Under the same rudder area, the control efficiency is better than that of the air rudder, which can make the missile move more agile.

However, the gas rudder is not very effective when used on medium-range intercepting missiles, because even in Gao Zhendong's previous life, most medium-range missiles were unpowered in the second half, so there was naturally no gas, and the gas rudder could not be used.

The AIM-9 family only started using gas rudders in the later 9X, so the 9B wreckage they had did not have this thing.
