The ups and downs of life in the Siheyuan

The funds for the laboratory were finally secured, and he felt relieved.

For Li Yuan, the three projects all have corresponding mature plans, so the consumption of materials will not be too much.

But for longitudinal research in the laboratory, he had to master a scale, not too quickly.

Instead, wafer preparation and lithography machine research can be blended into three projects.

After thinking about it for a long time, it was time to get off work.

Then the daughter-in-law returned home.

Yang Ting's belly has begun to bulge slightly.

Today's dinner is chicken stewed with mushrooms, stir-fried cabbage, tomato and egg soup and rice.

"Li Yuan, are our living conditions too luxurious? Many people don't have enough to eat now."

Due to adequate nutrition, Yang Ting's skin color appears shiny, soft, and full of elasticity when touched.

"I'm just a stinky baby like you, why do you earn so much money? If I don't spend it on you, stinky baby, I still have money left to have children!"

"You're the one who stinks!" Yang Ting felt warm in her heart.

Before her marriage, her mother talked to her a lot about men's bad habits and wanted her to learn to be tolerant.

But none of those bad habits can be seen in Li Yuan, only love.

Afraid that she would freeze at work, I specially made a three-bouncer with a stove.

Afraid that she would be homesick, he would take her back to her parents' home every once in a while, bringing some food with her every time to make her parents' life a little more comfortable.

At first, she was worried that this was not good. After all, a married woman would throw away the water. From now on, she would have to think about her husband's family in everything.

She secretly asked Li Yuan, and his answer always stuck in her mind: "Your parents have raised you so well and raised you so well. It is only natural that we have the energy to give back appropriately."

This made her feel reassured and moved.

"Li Yuan, if I give birth to a girl, will you be unhappy?"

Once a woman falls in love with a man, this man is the only one in her world.

"Girls are so good! It's daddy's little cotton-padded jacket."

Li Yuan put down the bowl and chopsticks, hugged her gently, and kissed her on the mouth.

"Don't worry, I don't care about that here.

The old tradition in the past was to raise children to provide for old age. With my ability, I will have enough money in my old age.

By then, even if we don’t have children, we won’t have to worry about taking care of ourselves in old age.

When the children grow up, they will also go to various places to build the motherland. By then, no matter how many children there are, we and the old couple will not be able to depend on each other.

When the time comes, I can no longer walk, and I will have to rely on you to hold me up.

Therefore, for the sake of my happiness in my later years, I must not support you every day now.

This is like depositing money in a bank. I store the good things I do to you in your heart, and when I get old, I can get the good things you give me in return.

So, I want to save more, hahaha. . . "

Li Yuan's teasing made Yang Ting put down her worries.

Nowadays, boys are favored over girls, and girls are treated as losers. She has been worried that Li Yuan is the same.

His answer may sound unserious, but if you think about it carefully, it's really the case.

She stopped eating, hugged the other person's waist tightly with her hands, and pressed her head against his chest.

"Okay, let's eat, otherwise we'll get cold."

This is Li Yuan's daily life. It's not boring to be together every day.

The days are passing by so fast, the end of the year is coming soon, and in another half month, the Spring Festival will be here.

On the test bed of a research institute in the southeast, the turbojet-6 modified engine that Li Yuan had just modified was placed.

Just looking at the appearance, we can see that there are a lot fewer pipelines on the engine, some new cables, and some more accessories.

The original 10 combustion chambers had 10 oil pipes, but now there is only one.

Then there is an extra annular fuel supply pipe, and all the fuel injectors are connected to this annular pipe.

There is an extra bump on the ring tube with some cables attached to it.

This bump is square and square, about 20*20cm, with various cables connected to it.

The cables have special wiring troughs, which looks much neater in appearance.

"Yeah! This engine looks much better than the previous one, and there are a lot fewer oil pipes. At least the maintenance difficulty will be much reduced."

The old general who often appeared on product trial occasions appeared on the scene again.

Several technicians in white coats gathered together in the distance.

A middle-aged man looked at the young man accompanying the old general with disdain in his eyes.

"It's all fancy, but if the engine was so easy to modify, we would have been eating free rice for so many years."

"Yes, Lei Gong, Big Brother has come forward and has brought more than 20 experts, but they can't solve it. No one dares to make such a big change," another middle-aged technician agreed.

"It's true that newborn calves are not afraid of tigers. Aviation engines are the pearl of industrial manufacturing, and not everyone can get involved." The middle-aged man known as Lei Gong curled his lips.

They have the capital of pride. They are technicians from the two major aircraft manufacturing plants in the north and the south.

Flight data is being collected on site in Kyoto in preparation for engine optimization.

The leader of the southern team was an engineer named Lei.

The leader of the northern team was an engineer named Liu.

The two of them have been old friends for many years. Liu Gong once studied in Damao, and Lei Gong studied in America.

Currently they are all experts on the turbojet-6 engine, and their main job now is actually studying the turbofan-5.

The Turbofan-5 is a new generation of mainstream aeroengine developed completely independently.

It is a technical indicator proposed based on the requirements of the Air Force to improve the H-5 bomber. Based on the turbojet-6 engine, a rear fan turbofan engine has been developed.

Turbofan 5 is a useful attempt for my country in the field of aviation technology, and it keeps pace with the world's technological forefront.

However, the rear fan type is not the mainstream of turbofan engine technology, and research and development was stopped in the 70s.

If research and development can continue, it will be of great inheritance value for my country's early independence of aerospace engines.

After the change, we introduced engines from many different countries and changed the direction of research and development again and again.

As a result, our country has been able to achieve most imitation production for a long time and cannot achieve technological breakthroughs.

The whispers from people around them have little impact on a few leaders.

Today, Li Yuan also invited his superiors to attend the launch meeting for the test and verification of the modified machine.

"Okay, it's a mule or a horse coming out for a walk."

"Okay, leader." Li Yuan walked to the console in person and turned on the power switch.

Because it was completely electrically controlled, neither the turbojet-6 technicians nor the pilots present knew how to operate it.

So Li Yuan could only do it himself.

After a period of self-test, the device normal indicator lights up.

Let me say here that the indicator lights currently used are still electronic tubes, not the LED lights of later generations.

The research and development of LED lights has been put on the agenda. It is still in the experimental verification stage and cannot keep up with this improvement.

When the normal indicator light on the console lights up.

Li Yuan made a gesture to everyone and shouted: "I'm going to start!"

Some people immediately covered their ears.

Li Yuan pressed the start button, and the sound of a motor starting came out, and the rotor was driven and began to rotate.

"Yeah! The sound of this motor is very small, it doesn't look big, and it has enough power," a test pilot nodded.

Others around him nodded.

After more than ten seconds, when the rotor reaches the ignition speed, the "ignition ready" indicator light turns on.

Li Yuan raised his left fist high, and then slowly opened it, reminding everyone that the fire was about to start.

After a few seconds, Li Yuan decisively pressed the start button.

A loud roar reached the ears of everyone present.
