Siheyuan: Rise from Sign-in

Chapter 779 Major Economic Issues!

With the successful roll-off of the engine, the process of the body of the new fighter jet has also been accelerated. The smelting workshop at the rolling mill is continuously producing various alloys used in the new fighter jet.

As for the aviation department, after Hong Cheng and Bai Haishan brought back the news that the engine was off the assembly line, the entire aviation department felt the heavy pressure on their shoulders.

The engine has already been rolled off the production line, so the airframe is simpler and can be ready at any time. The rest seems to be their avionics system.

Although they got the high-end equipment they dreamed of, Rome was not built in a day.

Even with these devices, it will take time to get the avionics system out!

At this moment, they can't wait to use one day as two days. Don't think about it when they sleep.

Bai Haishan's eyes were slightly red when he saw the attitude of his subordinates who forgot to sleep and eat.

He is proud to have such a comrade!

As for the efforts of the Ministry of Aviation, He Yuzhu didn't know that he had been paying attention to the fatigue test of the engine these days. A truly successful engine is not simply a matter of successful ignition.

There are still many follow-up tests, especially the reliability and durability tests. If an engine is not reliable, there will be an accident in the sky, so what will happen.

And a qualified engine, service life is also an important criterion.

After all, a turbofan engine is expensive, and if it doesn't last long, even a big country like the beautiful country can't afford to replace it.

Therefore, the longer the service life of a qualified engine, the better it is of course.

The general service life of an engine is about [-] hours, but this engine has been modified by He Yuzhu, and some advanced alloys are used, so it is in He Yuzhu's estimation.

The service life of this engine can reach about [-] hours, and the interval between the first overhaul is no less than [-] hours.

Such data, even in later generations, is extremely advanced.

However, an estimate is an estimate, and to really get accurate data, a lot of testing has to be done.

You know, in future generations, the total testing time for a brand new engine can even reach 2 to 4 hours.

In order to shorten the test cycle, later generations will use dozens or even dozens of units to test at the same time, just to save time.

After all time is money.

But He Yuzhu didn't plan to use this method because he had no money.

After all, at this time, the country is waiting to be rebuilt, and money is needed everywhere.

And to manufacture an engine, the cost alone needs 10,000+ yuan. You must know that at this time, the annual salary of an ordinary worker is only about 400 yuan.

The value of an engine can be as high as that of workers for hundreds of years.

He Yuzhu dare not give birth to such a gold-swallowing behemoth casually.

Although He Yuzhu believed in the design drawings he produced, he was even more certain that there was nothing wrong with the engine.

But others don't know!

After all, a person's cognition is limited. Without the convenience of He Yuzhu, how can he believe that a new engine has no problems from design to production line.

Even in later generations, when an engine rolls off the assembly line from the design stage, how many tests, modifications and upgrades it will have to go through in the middle.

Therefore, in the eyes of Hong Cheng and Bai Haishan, the No. [-] machine is an experimental model, and it will not be too late to start mass production when the test results are fully released.

After all, the plane has not yet taken to the sky, and it will be safer to wait until it goes to the sky to truly confirm that there is no problem with the engine.

He Yuzhu didn't object to this either. After all, this is the correct process, and no one else has cheated.

Boom...·

The limit test is still going on. Although it took three days, the engine is still working as before, and the hot flames are erupting, keeping the temperature of the entire workshop at a very high value.

But even so, none of the staff working here complained of suffering or tiredness, and everyone was working hard, recording every data.

Time passed, when the sun slowly set, He Yuzhu finally came out of the workshop, wiped the sweat from his forehead, He Yuzhu let out a long sigh of relief.

I really don't know how those seniors endured such a boring job, especially those who are in the depths of the desert at this time.

The working environment is even harsher than here.

But in such an environment, those seniors did something that shocked the world.

Thinking about it, He Yuzhu felt incredible!

"Director He!"

Just when He Yuzhu sighed, Secretary Wu ran up to him anxiously.

"What's wrong? Secretary Wu?"

He Yuzhu looked at each other with some differences.

"Something went wrong! Director He, Director Yang told you to go there quickly!"

what?

He Yuzhu was stunned for a moment, something big happened, what big thing could happen!

Why doesn't he know?

He's in the rolling mill these days!

He Yuzhu just wanted to ask clearly, but suddenly he seemed to understand something, and he swallowed back the words that came to his lips.

There was also a look of understanding on his face.

"Okay, then I'll go there!"

……

When He Yuzhu followed Secretary Wu into the office of the director of the rolling mill, the first thing he saw was Yang Weimin's serious face.

"Director, what's the matter? What happened? You asked Secretary Wu to find me so urgently?"

Seeing that He Yuzhu could still figure it out, Yang Weimin frowned and gave He Yuzhu a serious look.

"He Gong, what time is this, why are you still laughing!"

hehe…·

He Yuzhu laughed again.

"No, factory manager, what time is it, why can't I laugh anymore, the sun is going to explode tomorrow!"

I!

Yang Weimin looked at He Yuzhu's teasing appearance, and almost didn't come up in one breath.

He found that He Yuzhu was really not in a hurry at all!

On the contrary, he, an outsider, was as anxious as a grandson.

This!

Yang Weimin was depressed!

Seeing Yang Weimin's constipated face, He Yuzhu knew that the joke should not be too much, Shuran's face was startled, and he became serious.

"Okay, no kidding, factory manager, what happened when you called me here?"

Seeing He Yuzhu straighten his expression, Yang Weimin gave He Yuzhu a resentful look before he spoke.

"He Gong, you really haven't heard any news?"

"What's the details, factory manager, just tell me if you have something to say, I don't know anything."

Although He Yuzhu already had a guess in his mind, He Yuzhu didn't say it out loud. It wasn't a big deal anyway, so why did he bother thinking about it.

Seeing that He Yuzhu really didn't know anything about it, Yang Weimin had no choice but to tell the story.

"He Gong, it's like this. Someone reported that you have a major economic problem. As the head of the rolling mill, I have the responsibility to find out the facts. As for you, He Gong, as a party involved, do you have anything else to explain?"
