The blades of the airflow squeezed by the aircraft engine are smaller the diameter of the entire blades as they go into the engine, but the dense arrangement of more than ten layers of blades can form a very stable effect of air-induced diversion, assisting the engine to divert the air flow that is rushed in, thus forming a forward thrust.

Currently, the latest engine fan blades are made of composite materials. This composite material is mainly high-temperature alloys that can withstand high temperatures caused by high-speed rotation and will not deform.

It is also covered with titanium alloy to protect the engine blade from breaking and damage during high-speed rotation, and can be easily replaced during maintenance.

High-temperature alloys, also known as thermally strong alloys, can maintain normal working conditions under high temperature environments and high pressure conditions under strict working standards.

This high-temperature alloy is not only resistant to oxidation and corrosion, but also can cope with complex fatigue environments. It can even withstand high temperatures up to 600 degrees to 1200 degrees without any deformation and damage. The strength of the high-temperature alloy and the toughness of the tensile steel fracture resistance are all very powerful.

However, this high-temperature alloy cannot be produced in China at present, and the titanium alloy warrior steel plant has been able to mass produce it.

Because it has decided to set up an aircraft manufacturing plant, high-temperature alloys are the top research and development task of steel plants today.

However, Sergei and Sergei still have some experience with this thing. After all, the former Soviet Union has always been one of the countries that can independently produce aircraft.

As soon as he entered the factory, the third brother became busy like an ordinary worker. With Luke's instructions, no one cared about the management in the factory, and basically he would let him go whatever he wanted.

The third brother kept shuttled between various jobs, going wherever he needed it. At the end of the day, he compared the workload of anyone who had a higher workload, so the workers didn't like him.

When I got off work, the third brother dragged his tired body and walked out. He kept thinking about the production processes of those turbines in his mind.

With a "bang", she collided with a woman coming towards her, and the woman sat on the ground.

"Ah" The third brother woke up and reached out to pull the woman, but the woman cried out in pain and couldn't get up. The third brother observed it and must have hit the tailbone when he sat on the ground.

After human evolution, this bone is completely useless. But it will hurt even if it can't be held back? The woman was crying in pain, but she tried her best to make no sound, looking very strong.

When the third brother saw this, he no longer hesitated. He picked her up and walked towards his car.

"Where is the hospital? You want to give me some advice. I just came to Germany and I am not familiar with it."

The woman shook her head: "No need to go, I'm fine, just take a break."

The third brother ignored her and put her directly in the back seat. The woman screamed again, it seemed that she had touched the tailbone again.

She turned her body hard and sat half of her body so that the tailbone would not be affected.

When I arrived at the hospital, the third brother hugged her all the way, because she felt so painful because she put it on the activity bed.

After the examination, there was nothing wrong. It was just that when I fell, my tailbone hit a stone, so I could just rest in this way.

The woman's name is Helena. She has just graduated from Hamburg University and works as a technician in the factory.

Helena is not beautiful, her face is rough and stiff. Just like a new student in the Academy of Fine Arts.

With her size of about 1.8 meters, people don’t feel any feminine beauty. Anyway, the third brother holds her and has no ripple in his heart, just like holding a buddy.

Since it was okay, the third brother had to send her home. However, Helena said that her home was not in a hamburger and she shared a rent with others, but it was really inconvenient to go back now.

The third brother had no choice but to bring her to his home. There were several rooms, and it was not a big problem to let her stay in one.

After putting her down, the third brother found that he was sweating too. He went to take a shower first and then started to make some food.

He was supposed to come back after dinner, but Helena made the plan messy. At least he bought bread, sausages and Chinese instant noodles when he went to the supermarket yesterday.

He heated up all these things, then brought them to Helena, and carefully applied butter cheese to her.

Helena looked at the third brother obsessed with her little bite, and her heart was filled with emotion. It was the first time that a man had taken care of her like this when he grew up so old.

Seeing that she was only gnawing bread, the third brother picked up a bowl and asked her to eat noodles. Helena had never eaten this thing. She liked it very much when she tasted it. She stopped gnawing bread and quickly ate a bowl of instant noodles.

After dinner, the two of them chatted for a while. The third brother was surprised to find that Helena had a very thorough understanding of the engine, and many of her views even surpassed him, which inspired him a lot. So the more she talked, the more she became more and more speculative. Before she knew it, it was midnight.

Seeing that the third brother was obviously tired of sitting, Helena patted her bed: "Lying down, so we can communicate more comfortably."

The third brother is not pretentious either. Science and engineering men have this common problem. When they encounter topics they are interested in, they always don’t care so much about things outside the topic.

Neither of them knew when they fell asleep. When they woke up, the third brother was putting his hand into his clothes.

Helena's face was flushed. It seemed that she had never experienced such things. She was tight and turned herself into a wooden stick.

The third brother took his hand back with a embarrassed look on his face, and he was still savoring it in his heart.

It’s not that the third brother is not picky about food, because at this moment, he has not linked Helena to the opposite sex, mainly because except for some places, she is really no different from herself!

He is taller than himself and stronger than himself. The third brother probably would have to be able to live together if the two of them lived together.

"Jack, can I discuss something with you?" Helena said with a red face.

The third brother nodded without hesitation: "You said, as long as I can do it, I will definitely agree."

"I want to live with you, but it's too inconvenient for me. Of course, I will give you a rent and my living expenses will be equal to you." Helena said, and then let go and no longer shy.

"Okay, I can have a companion too. You don't have to give me money. Anyway, I have paid a year's rent. You can live here before I return to the United States." The third brother naturally would not ask for a woman's money.

But Helena insisted: "You have to collect money, otherwise I won't move in."

"Okay, okay, this is up to you." The third brother was unwilling to bother with these things, so he followed her.
