The ups and downs of life in the Siheyuan

The angry deputy director returned to the team and explained to everyone.

Suddenly, the older people were filled with indignation. On the contrary, the young people felt normal, but on the surface they shared the same hatred.

The two deputy factory directors discussed it in low voices, each looking for someone, vowing to stir up trouble.

Regardless of the external chaos, Li Yuanxin is "wind tunnel research".

Tried and tested, tinkered with the size and proportions of the ducts, and still remained completely obsessed.

In the past few days, the maintenance shop and surrounding residents can always hear the harsh howling of the wind.

Fortunately, it was only during the day, otherwise, everyone would probably complain to the street.

Just like this, some old people couldn't stand it anymore and found the streets.

After receiving the notice, Li Yuan had to put the experimental period at noon.

Only open for 10 minutes at a time.

In order to increase the wind pressure, fans are getting bigger and bigger, and the diameter of the fan is now as fast as two meters.

Connected to the fan is a large bell mouth, and at the end is a 5*5 nozzle with a sharply reduced aperture.

Li Yuan personally stood in front of the matrix nozzle and felt the wind speed, feeling like he was facing a strong wind.

Even with his thick skin, the wind would hurt his face.

It's a pity that it has never been blown up by the wind.

Although the wind speed is not satisfactory, it is still feasible to simulate airflow disturbances and mutations.

Due to limited conditions, we can only achieve the current level. Anyway, we already have a model. If the military values ​​​​it, it can design its own equipment with greater wind power.

Thinking of this, he thought that he could design some engine models in the future and provide them to the military for reference design after success.

Each nozzle of the "wind tunnel" is controlled by a solenoid valve. The control panel does not use a chip, just a simple 5*5 matrix button.

This is the result of Li Yuan's research and development for nearly half a month.

When a truck drove away from the maintenance shop, all the employees in the factory breathed a sigh of relief.

Some nearby residents waited for the sound of wind howling at 12 o'clock, but they couldn't wait for a long time.

Many people couldn't accept it and started making noises one after another.

It wasn't until I didn't hear anything from now on that I finally released the anxiety in my heart.

Southwest Military Equipment Experimental Base.

Li Yuan's appearance caused a commotion, and the two engines had been tested continuously for 220 hours.

Every time I stop and check, I can't see any abnormal behavior.

Everyone knows that these two engines will create the history of China Aerospace Engine.

I pray silently every day, waiting for that day to appear.

Seeing the smiling Li Yuan, the two deputy factory directors stared at him with complicated eyes.

In the past half month, they used various connections and finally found Li Yuan's home address without waiting for them to take any further action.

I was invited to have tea by the Investigation Department.

When they walked out of the investigation department, they had a new understanding of Li Yuan's strength.

A technician protected by the Investigation Department definitely has secrets that they don't know about.

They have been sternly warned to strictly abide by the confidentiality system and not to tell others about Li Yuan's information.

When their own technicians gathered around, they did not stop him, but watched from a distance.

Li Yuan directed several soldiers to unload the large fan from the vehicle.

Then, in full view of everyone, he started to assemble himself.

They were all simple gadgets. After assembly and debugging, within an hour, a strange-looking thing appeared in front of everyone.

Seeing such an ugly thing, everyone was talking a lot.

At this time, the excited representative Tong had already asked someone to transport an old engine.

The old general who got the news appeared at the base again.

My interest in this big toy increased greatly and I kept asking questions.

Everything is connected properly, and a new experiment starts on the other end.

When Li Yuan kept adjusting the combination of nozzles, the engine suddenly made a surging sound.

The test driver stopped immediately.

Repeated many times, surge occasionally occurs.

The last time it happened, before the test driver could stop the car, the engine vibrated violently and then stopped automatically.

Fortunately, there was no explosion, but everyone was shocked.

Without inspection, this engine must have been scrapped, because bulges can be seen on the casing of the subsequent engine.

The blade or wheel must have broken off and it was flying around inside.

The engine loses rotational power and automatically stops.

Although one engine was scrapped, the old general was very happy.

"Okay, with this ugly thing, in the future, pilots will no longer have to spend their lives to find problems. Problems can be found and solved on the ground.

Li Yuan, you have given me so many surprises, no, I have to take action."

"Chief, this is just a toy. If it wants to be truly effective, it must be redesigned based on this principle and increase the wind speed to supersonic speed.

This big guy just simulates airflow disturbance."

“If we have a model and a principle, I think everyone can implement it.”

He looked at the person in charge of the base, "Can it be done?"

"Report to the leader and ensure the completion of the task."

The person in charge of the base looked at Li Yuan and said, "Comrade Li Yuan, you must support our work more in the future."

"No problem, I'll be there when you call."

The two deputy factory directors looked ugly after hearing Li Yuan's answer.

The old general looked at the two deputy factory directors again. They immediately changed their expressions and took a few steps forward with smiles.

“You must learn more from Comrade Li Yuan in the future. You must not blindly pursue output, but must pay attention to quality and carry out innovation.

Comrade Li Yuan is just an outsider, but he has done many things that none of you experts can solve.

Take this airflow disturbance gadget as an example. It doesn’t look complicated and the principle is very simple.

Didn't Xiao Li say that it was inspired by the principle of the turbojet-6 compressor?

There are so many of you, but none of you think about this? I don’t think so!

To mobilize the masses and believe in the masses, only front-line workers have the deepest feelings.

Many creative ideas do not require much knowledge, but rely on boldness and carefulness.

We must believe in our master workers that many small ideas can solve big problems."

The two deputy factory directors could only nod in agreement.

When the old general returned his attention to the second improved turbojet-6, the smile on his face was hard to hide.

“With more than 200 hours, both engines have easily exceeded the life limit, and they seem to still have power left.

OK, if every one performs like this, our fighter will have a strong heart.

Then you don’t have to risk your life! ".

He looked at Li Yuan again, "You don't need to look at the final results, just the current results, I can take credit for you.

I can't wait to see the final data.

There is hope, it will take a little longer, and hope will last forever.”

Everyone laughed along with him.

Li Yuan was not modest this time, "Thank you, chief, for taking this seriously!".

"It's not that I value you, but you impressed everyone with your results," the old general said with emotion.

He is really happy.

He didn't expect this version of changes to have such good results.

What excites him even more is that during the experimental period, Li Yuan did not stop his research, but developed another large toy that simulates a wind tunnel.

The principle is clear at a glance, but the effect is very obvious.

This gave him hope that with so many people in our country, as long as everyone pays attention to the details in their work, they can make breakthroughs.

He felt he had found the magic weapon to win.

Looking at the excited old general, Li Yuan did not pour cold water on him.

He knew that the old general's wishes were good, but invention and innovation were not that simple.

Not all enthusiasm can overcome everything, but the right soil is needed.

And what we in China lack now is excellent fertile farmland.
