Qin Guan knew this history, so he hoped more for the strength of his motherland. Since he came to this parallel world, he had to use his strength to prevent these tragedies.

Think about the situation back then, it makes people angry.

The assembly line of "Yun 10" was removed to make room for McDonnell Douglas. The technical data accumulated over the past 15 years do not even have a place to stack, and many of them have been lost.

The materials worth tens of millions of yuan originally prepared for the third "Yunshi" were used to practice rivet guns when preparing for cooperation with McDonnell Douglas!

Yunshi came to an end in this way. From then on, there was no big plane produced by itself in the sky of the Han country. The market of hundreds of billions of Eagle yuan is mostly divided by Boeing and Airbus. They fly freely in the sky of Han country and happily earn the wealth created by Han people at the cost of blood, sweat and environment.

I remember a person said that after having two bombs and one satellite, the state of Han should do two major things: one is to have its own aircraft carrier in the sea, and the other is to have its own large aircraft in the sky.

Unfortunately, it took half a century to have these two things after having two bombs and one satellite.

Thinking of this, Qin Guan's heart could not be calm.

Then he heard the conversation behind him.

The tickets ordered are all next to each other. Behind Qin Guan is old Wu. Next to old Wu is Li Yong.

Li Yong got the highest score in the written test. When he saw Li Yong's test paper, Wu was very happy. He called Li Yong over and asked all kinds of questions himself. Then Li Yong was called Wu's assistant.

Mr. Wu is vigorously promoting new people and developing engines. He should not only have profound knowledge, but also have considerable physical strength. When the engine is tested, people need to endure.

Wu laobi is old. Now, I feel very happy to have Li Yong around.

Although Li Yong has always been a temporary worker, he has participated in the imitation of Spey engine. Now, he knows the problems one by one.

"Now, one of the biggest obstacles we encounter in the process of imitating Spey engine is the production process of primary compressor blades."

In fact, the principle of aviation turbine engine is not complicated. In front of it are fans in series, called compressors, which are like electric fans. They blow air into the combustion chamber behind them. The fuel injection and combustion in the combustion chamber generate high-temperature and high-pressure gas, and then blow the turbine blades behind them and spray it out at the same time.

When the turbine blade rotates, it can drive the compressor in front, so that it can rotate continuously.

This is the turbojet engine. If a large fan is added to the front, a cylinder is set outside to let part of the air flow blow directly to the back as the driving force. This is the turbofan. This cylinder is called the outer culvert. It makes more clever use of the rotating force to increase the pushing force, so it can save fuel.

The principle is very simple, but there are many difficulties in specific operation. For example, the rear turbine blade needs to be resistant to high temperature and high pressure. 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 air flow will cause distortion, which is easy to make the engine unable to work normally.

Now, in the Spey engine, the front is the blade of the outer culvert, and then the back is the blade of the first stage compressor.

These blades are integral precision forgings with a long length and torsion, and they also have damping bosses for shock absorption. It is completely different from the turbojet-7 produced in China.

No one knows how to produce the blade with this strange shape and how to design the forging die. The production of this blade is difficult for his own side.

"If we want to localize Spey, the production process of this primary compressor blade must come over," Wu said.

The localization of Spey is of great importance. Now, no matter how many difficulties we encounter, we must overcome them.

Moreover, there is the Qin Guan. Seeing the Qin Guan in front, old Wu has confidence in his heart. As long as there is the Qin Guan, nothing can not be solved.

At this time, Qin Guan had fallen asleep in his seat.

The long flight finally ended. The plane landed at NiuGuo capital airport. This honeymoon trip is finally about to begin.

When Qin Guan stepped off the plane, he started his mental point scanning.

Xiang Jing and the scholar, one before and one after, guard beside Qin Guan. From this time on, they will perform their duties as bodyguards and must protect the safety of Qin Guan.

The two of them are in the Ming Dynasty. At the same time, there are several national security personnel in the dark. However, for Qin Guan, it is better to solve his own safety.

Like now.

As long as Qin Guan starts the mental point scanning, the values will float above everyone nearby.

If there are only dozens of mental points, it is normal passengers. If there are hundreds, it is special personnel. The common ones are soldiers, engineers, etc. if there are thousands of mental points, there is no doubt that they are powerful people with special training, soldiers of special forces or international killers.

Everything is under control.

Beside me, except Xiang Jing and scholar, there is no one else's spirit. I'm just an ordinary factory director. It's so simple to travel with a group of technicians and won't attract much attention.

Chen Yutong's heart is full of joy. The capital of NiuGuo is a world-famous 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 the goddess of victory standing on the top.

Go to the Thames to see the Gothic Tower Bridge and the famous scenery on the Thames.

This is my honeymoon.

At this time, brother Qin Guange suddenly stopped.

"Mr. James, it's amazing that you are here," Qin Guan said.

The military attache of Niu state in Han state is at the airport?

"Yes, I came here specially to welcome you." James said, "in the Han Dynasty, I saw the wonderful performance of your fighters. Now that you are here, we have prepared a wonderful performance for you. Would you be interested in watching the performance of our fighters?"

"OK," said Qin Guan, "but my wife is not interested in it. Xiang Jing, can you take Yutong for a walk in the city?"

Chen Yutong was stunned. Brother Qin, this is our honeymoon trip. What do you mean by letting Xiang Jing take me? Even if you walk with me for a long time, will you be separated?

"OK." Chen Rui in the back has already spoken. Niu Guo's advanced aircraft wants to have a try.
