Chapter 266 Air Rudder Gyro Rudder and Gas Rudder
Gao Zhendong didn't know what was happening in the distance. He was now working with Yu Yuncheng to receive the batch of graphite components that Duan Gong mentioned a few days ago.
Now that the Li single crystal furnace has officially produced the target silicon crystal, everything is ready, all it needs is the east wind.
This east wind refers to this batch of graphite components from the Carbon Research Institute. We can use them to replace and supplement some of the graphite components of the single crystal furnace.
The two of them verified and counted the graphite components and found that there were no problems.
While Yu Yuncheng and Gao Zhendong signed the handover procedures together, he said happily: "Director Gao, we will replace the graphite components as quickly as possible and make final preparations such as roasting the new components. It is estimated that we can start work on Saturday. The test has officially begun.”
Gao Zhendong was also very excited, but still told him: “Pay attention to the test system and related requirements. You can’t eat hot tofu in a hurry. The time has passed. Don’t give up on the last tremor. "It's a trap."
Yu Yuncheng naturally knows this: "Well, I will pay attention to it and have already taken these factors into consideration."
He is also an experienced researcher. Gao Zhendong mentioned this matter mainly to be more safe.
Gao Zhendong returned to his office with the graphite-backed tungsten-molybdenum alloy throat liner sent back by the Carbon Research Institute, including the test pieces after the test and the extra brand-new pieces.
In addition to these, there was also a package sent by Duan Gong along with the components. Although he did not know that Gao Zhendong was married when the package was sent, according to his habit, he sent something as usual.
When this old man should be careful, he is very careful.
Not to mention, these things together are really not light. If Gao Zhendong hadn't been strong, he really wouldn't have been able to get rid of them.
Opening the package delivered by Duan Gong, they mainly include food ingredients, pickled products and dried products. It’s not that Duan’s gift is not innovative, but that this stuff is the most practical these days, and everything else is the same. Bullshit.
After keeping some strange things for himself, Gao Zhendong packed the most practical ones, such as Datuo’s dried meat, into a bag again and sent it to Lao Chen.
At this time, material supply has gradually begun to have an impact on people at Lao Chen's level. Fortunately, the overall situation is not as bad as I heard in the previous life.
Mr. Chen looked at the package Gao Zhendong brought over and said with a smile: "Are you planning to sugar-coat me?"
Gao Zhendong put the things in his cabinet. : "Those who show filial piety to their master will not go so far as to have nothing but sugar coating and no shells, haha."
Old Chen also knew Gao Zhendong's thoughts and was very pleased with his filial piety. He gave himself When sons who work far away write letters home, they often write: "Junior brother is very filial. With him here, when you are working far away, don't miss the two elders at home."
Back in his office, Gao Zhendong looked at the remaining few brand-new tungsten-molybdenum alloy throat liners and remembered something, so he called Lin Lianwei, a classmate at the Institute of Guidance and Research.
This call took a lot of trouble. After all, Lin Lianwei was not like Gao Zhendong. There was a phone in the office. It took a long time to contact him.
Lin Lianwei still had the same offbeat tone: "Haha, Lao Gao, what's the matter?"
He knew that Gao Zhendong would not call him if there was nothing serious. Talking on the phone is not popular these days.
Gao Zhendong was also infected by his tone: "Yes, there is something good, come over as soon as possible, I will give you a new thing here."
Gao Zhendong took the initiative Are you talking about something new? When Lin Lianwei heard this, he said without saying a word: "Okay, I'll be right over."
After hanging up the phone, he immediately ran to Gong Lu to ask for leave: "Gong Lu, the senior consultant of our hospital has something to do with me. I'm going to ask for leave and come over."
"Counsel Gao?" Gong Lu I was a little confused by the formal title in his words.
"Gao Zhendong, my classmate."
"Hey, just tell me Director Gao, what are you talking about? Go ahead and go."
Gao Zhendong He took the initiative to find Lin Lianwei, and Lin Lianwei came to ask for leave in a serious manner. It must be official business, and it was probably something good.
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 you go, see if you can use them. If you can, then go back and let you use them." The hospital reported to us and asked for the formalities. "
It would be impossible to take him away directly. Gao Zhendong himself was fine, but Lin Lianwei was trapped.
Lin Lianwei weighed the weight of the throat lining, and then took the test report and read it.
Although he is an automation major himself, he has been exposed to it at the Institute of Guidance and Research, so he is considered to be across the industry. He also has some understanding of engines and has asked Gao Zhendong related questions before.
So he could roughly understand what kind of material the test report Gao Zhendong gave him represented.
"Zhendong, is this test report true?" "How fresh it is. Can I make a fake report to tease you?"
Lin Lianwei also Knowing that what he said was a bit unreliable, he rubbed his head and smiled.
"Zhendong, can you take this report with you?" He can understand the parameter characteristics, but there is no doubt that no one who is professional in fixed hair is as proficient in the meaning and changes that the parameter characteristics can bring. , so his idea is very simple, I will take away the information and show it to professionals.
"No." Gao Zhendong's answer was concise and powerful. Lin Lianwei's face suddenly dropped. He can't be taken away. You are teasing me. My eyes are not cameras.
Gao Zhendong, who succeeded in pranking, laughed loudly: "Haha, but you can make a copy. There are only a few copies of this original copy. What will I use if you take it away."
Lin Lianwei's Only then did he become happy. He didn't care about talking nonsense with Gao Zhendong, so he took out a pen and paper and started copying.
Lin Lianwei was still complaining while copying: "This time, I can be regarded as sharing the tasks for the engine gang. Our guidance does not have use for this thing, but I still have to copy books for them here. "
Gao Zhendong smiled and said: "Shut up, besides, you may not be able to use it. "
The test report is not long, but it is not short either, especially since it also contains original test data processing, analysis, charts, etc., but Lin Lianwei had a hard time copying it.
Because he strives to be consistent with the original, the numbers and text are easy to describe, but the chart is more difficult. Although Lin Lianwei is a top student at Pudaokou College, his drawing skills are not weak, but he cannot handle the large number.
The data processing and analysis of the Carbon Research Institute is very detailed, and the intuitive result is that there are many pictures.
After finally finishing copying, Lin Lianwei said goodbye and turned around to run away.
Gao Zhendong was puzzled: "Why are you running? I'm about to get off work in just a few hours. You take a rest here. I'll treat you to dinner after get off work. After dinner, I'll leave."
Lin Lianwei picked up the copy of the test report in his hand and raised it: "What the hell, 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 business. , Lin Lianwei was still reliable, and he didn't even bother to eat. He immediately said goodbye to Gao Zhendong and returned to his courtyard.
He pedaled hard all the way on his bicycle, so fast that when he returned to the yard, it wasn't even time to get off work.
He put the report in front of Lu Gong: "Lu Gong, there is indeed something good in Zhendong. I brought the report back. Take a look, but it seems that this thing is mainly used by Gufa. "We are of no use." He said with regret.
They are making guidance systems. This thing looks to be temperature and pressure resistant. Isn’t it just going to be fixed?
Lu Gong did not comment, picked up the report and read it carefully.
After reading for a while, he took the report and knocked Lin Lianwei on the head: "You are ignorant and incompetent, who said we can't use it?"
Lin Lianwei covered his head. Head: "What can we do with this thing?"
Gong Lu said with a smile: "Gas rudder! Although the one we are imitating cannot be used for the time being, it will be hard to say in the future."< br>
Although the gas rudder seems to be installed in the tail nozzle or behind the butt, this thing is really not an integral part of the engine. It will have an impact on the design of the engine. After all, it is installed where the airflow ejects. But from the perspective of system composition, this thing is part of the guidance system.
Lin Lianwei: "What is a gas rudder?"
This is not to blame Lin Lianwei for being ignorant, but because he has never been exposed to this thing. The prototype of the air-to-air missile they copied, the AIM-9B "Sidewinder" , there is no gas rudder, and its direction control mainly relies on the canards in front of the missile body, which is actually a set of air rudders.
There is also a set of gyroscopic rudders on the sidewinder's huge tail, but that thing is responsible for controlling the roll of the missile. During the flight of the missile, the airflow blows the gyro, and the precession effect of the gyro produces torque suppression. The missile rolls and remains stable.
The wonderful thing about this set of things is that its rotational speed automatically changes according to the flight speed of the missile. It can effectively suppress the roll of the missile within the speed range of the missile. It uses pure aerodynamic force. The scientific and mechanical principles are not cross-linked with the missile guidance system at all.
But this seemingly simple gyro rudder, which is not cross-linked with the guidance system, suppresses the roll of the missile during flight and allows the missile to adapt to a larger G value. Simply put, it is more maneuverable. Well, it turns faster.
Lu Gong explained the principle of the gas rudder to Lin Lianwei, and Lin Lianwei was stunned for a while. After all, he came from an automation background and was not majored in missile design. It was normal that he did not know about the gas rudder for the time being.
To use a lofty concept from Gao Zhendong’s previous life, the gas rudder is actually a thrust vector control method.
Using the deflection of the rudder body in the high-speed gas flow to generate control torque, under the same rudder area, the control efficiency is better than that of the air rudder, making the missile more agile.
However, the effect of gas rudders on mid-range interceptor projectiles is average, because even in Gao Zhendong’s previous life, most mid-range projectiles were unpowered in the second half, and naturally there was no gas. There is no way to use the rudder.
The AIM-9 family only used gas rudders in the later 9X, so the 9B wreckage they have does not have this thing.
