Chapter 300: Arrived in the capital of cattle country

Qin Guan knows this period of history, so he hopes that the motherland will be strong. Since he has come to this parallel world, he must use his strength to prevent these tragedies from happening.
It makes people angry to think about the situation back then.
The assembly line of the "Yun Ten" was removed and made a place for McDonnell. The technical data accumulated over the past 15 years has no place to pile up, and many of them are lost.
Originally planned to make the third "Yun Ten" worth tens of millions of yuan, in preparation for cooperation with McDonnell Douglas, I used the rivet gun!
Yunshi ended without a problem. Since then, there is no big airplane produced by itself in the sky of Han. The market of hundreds of billions of eagle dollars is mostly divided up by Boeing and Airbus. They fly freely in the sky of Han, and happily earn the wealth created by Han Chinese at the cost of blood, sweat and the environment.
I remember one person said that after Han had two bombs and one satellite, it had to do two major things. One was to have its own aircraft carrier in the sea, and the other was to have its own big plane in the sky.
It is a pity that these two things were only acquired after half a century after possessing two bombs and one star.
Thinking of this, Qin Guan couldn't calm down in his heart.
Then he heard the conversation behind.
The tickets ordered were all seats next to each other. Behind Qin Guan, there was Mr. Wu. Next to Mr. Wu, Li Yong was sitting.
In the written test scores, Li Yong was the highest, with full marks. When he saw Li Yong’s test paper, Mr. Wu was very happy and called Li Yong over and asked various questions in person. Then, Li Yong said For Wu's assistant.
Mr. Wu is vigorously promoting newcomers and developing engines. It requires not only profound knowledge, but also considerable physical strength. When the engine is tested, people need to survive.
After all, Mr. Wu is old, and now, with Li Yong by his side, I feel very relieved.
Although Li Yong has always been a temporary worker, he has participated in the imitation of the Spey engine all the time, and now he knows all the problems.
"Now, in the process of imitating the Spey engine, one of the biggest obstacles we have encountered is the production process of the first-stage compressor blades."
The principle of aeronautical turbine engine is not complicated. The front is a series of fans called compressors, which are like electric fans. They blow air into the combustion chamber at the back, and the fuel injection in the combustion chamber. It burns to generate high-temperature and high-pressure gas, which blows the turbine blades behind and sprays them out at the same time.
The rotation of the turbine blades can drive the compressor in front, so that it can continue to rotate.
This is the turbojet engine. If you add a large fan in the front, and set a cylinder on the outside, let a part of the air flow directly blow to the back to act as the driving force. This is the turbofan. This cylinder is called the outer duct. , It uses the rotational force more cleverly to increase thrust, so it can save fuel.
The principle is very simple, but in terms of specific operation, there are many difficulties. For example, the back turbine blades need to be resistant to high temperature and high pressure, and special materials must be used. The higher the temperature, the higher the efficiency of the engine.
The front compressor must have sufficient redundancy. When the speed changes, the airflow will cause distortion, which will easily make the engine unable to work normally.
Now, in the Spey engine, the front part is the outer ducted blade, and the back part is the first-stage compressor blade.
These blades are integral precision forgings with long length and torsion, and there are damping bosses for shock absorption on the blades. It is completely different from the domestically produced Turbojet-7.
No one knows how to produce such a strangely shaped blade, how to design a forging die, the production of this kind of blade, it is difficult for oneself.
"We want to localize Spey. The production process of this first-stage compressor blade must be over." Wu Lao said.
The localization of Spey is of great importance. Now, no matter how difficult it encounters, it must be overcome.
Moreover, there is Qin Guan. Seeing the Qin Guan in front, Wu Lao has confidence in his heart. As long as Qin Guan is there, nothing can't be solved.
At this time, Qin Guan was already asleep in his seat.
The long voyage finally came to an end. The plane landed at Niu Country Capital Airport. This honeymoon trip is finally about to begin.
When Qin Guan got off the plane, he started his mental scan.
Xiang Jing and Xiucai were standing next to Qin Guan one after the other. From this moment on, they would perform their duties as bodyguards and must protect Qin Guan's safety.
The two of them were illuminating, and at the same time, there were several Guo'an personnel in the dark. However, for Qin Guan, it was better to solve for his own safety.
Like now.
As long as Qin Guan turns on the mental point scan, there will be a number of values ​​floating above everyone nearby.
If there are only dozens of mental points, then they are normal passengers. If there are hundreds of them, they are special personnel. The common ones are soldiers, engineers, etc. If there are thousands of mental points, there is no doubt that they are powerful and specially trained. People may be special forces fighters or international killers.
Everything is under control.
Apart from Xiang Jing and Xiucai, no one else has the spirit of over a thousand points. I am just an ordinary factory manager. Traveling with a group of technicians is as simple as that and won't attract much attention. of.
Chen Yutong’s heart is full of joy. The capital of Niu Country, but a world-renowned big city, when you come here, you must go to the square of Buckingham Palace to see the Queen Victoria Monument standing in the center, and see the wings spread on the top. The goddess of victory who wants to fly.
Go to the Gothic-style Tower Bridge on the Thames and see the famous scenery on the Thames.
This is my own honeymoon trip.
At this moment, Qin Guan, who was beside him, suddenly stopped.
"Mr. James, it's really amazing that you are here," Qin Guan said.
Niu's military attache in Han was actually at the airport?
"Yes, I made a special trip here to welcome you all." James said: "In Han, I watched a wonderful performance of your fighter planes. Now that you are here, we have also prepared a wonderful show for you. Are you interested in watching the performance of our fighter planes?"
"Okay." Qin Guan said: "However, my wife is not interested in it, Xiang Jing, can you take Yutong for a walk in the city?"
Chen Yutong was stunned, Qin Guan, this is our honeymoon trip, what do you mean by asking Xiang Jing to take me? Even if you accompany me for a long time, I will be separated?
"Okay." Chen Rui at the back had already spoken. Niu Guo's advanced aircraft wanted to give it a try.
