Chapter 219 Overtaking on a curve is not that easy

It is said that plans cannot keep up with changes.

So Fang Xiang didn’t stay in Beijing to accompany Liu Shuying for a few more days.

There was no time to think about and plan the next steps for selling the car.

Now, people have arrived in the Northeast.

“Well, the questions have been marked for you.

You brought this upon yourself, so you have to solve it yourself."

Professor Li leaned back, looking exhausted.

Yes, Fang Xiang was called over this time because there was a problem with the new design of the WP-7.

Almost a year has passed since Fang wanted to draw the picture.

During this period, Professor Li appeared and disappeared mysteriously, and Fang Xiang almost forgot that he had such a mentor.

But suddenly a phone call came in, calling Shen Fei.

Fang Xiang saw Wang Jinyang standing beside him and shrugged helplessly.

It seemed to be saying that there was nothing he could do.

Fang Xiang didn't say anything, but pulled the desk lamp next to him over.

After aligning himself with the drawing, he leaned over to look.

I spent a long time looking at the places marked on the drawing.

After comparing it with the drawings in his memory, Fang Xiang felt a little confused.

There's nothing wrong with this, right?

When I raised my head again and wanted to ask, I found that Professor Li had fallen asleep.

After taking a look at Wang Jinyang who was about to fall asleep, Fang Xiang gently pulled out the chair and patted Wang Jinyang's arm.

"Go out and talk."

Wang Jinyang woke up immediately, glanced at Professor Li, and said something in a low voice.

He quietly opened the office door and walked out first.

"Well, did you find any problem?"

It was not until he reached a small office downstairs that Wang Jinyang stretched out his arms and did some stretching exercises.

Yawned.

"Take me to the workshop to see the finished product."

Fang Xiang looked at the bloodshot in Wang Jinyang's eyes and knew that they must be very busy recently.

If I really didn't know what the problem was, I wouldn't call myself.

Looking at the bright sunny sky outside, I wonder how many nights they have stayed up.

But since we are here, let’s deal with the problem first.

“Here, here and here, every time I replace a new part, it always gets deformed.

This should be a question of strength.

According to the standards on the drawings, we simply cannot achieve that kind of strength in our country right now.

So, for this part, I just want to ask you if there is any way.

Last time I made a prototype, but it fell apart before it reached its maximum designed power.

After checking several times, I found that this was the problem.

According to the design on your drawing, this position should have a special coating.

However, several research institutes have been studying for more than half a year and are still unable to produce the standard you show in the diagram.

so. . . "

Wang Jinyang took Fang Xiang to the workshop.

Looking at the engine that is more than one meter high and placed on the stand.

And the busy staff walking around in uniform.

Wang Jinyang climbed up and down, pointing out the locations marked on the drawings one by one.

It was not until the end that Fang Xiang realized that it was not a problem with the design of the drawings.

It’s still a question of materials.

“Were there any problems with accuracy?”

Fang Xiang pursed his lips and pondered for a long time, realizing that they must have repeated the experiment countless times.

None of them succeeded, so they found themselves the culprit.

I think they are already questioning the drawings they designed, wondering if they deliberately increased the difficulty.

“It has appeared before, so I specially found several level 8 workers to polish it by hand.

There have been no accuracy issues since then.

But these few places are not problems that the workers can solve. . . ”

Wang Jinyang understood Fang Xiang’s meaning and could only tell the truth.

“In fact, the professor has thought about changing you, but it is not possible to implement it at the moment.

Change back to the current mature design.

But I found it a little difficult, because in many places, moving a single hair would affect the whole body.

Changing those few small details is almost equivalent to completely revising the drawings.

Some gain outweighs the loss.

Now we have conducted more than ten rounds of experiments.

Not once was it satisfying.

The pressure on professors is enormous. . . ”

Wang Jinyang looked at the engine on the test bench, with a sigh in his voice.

"Give me some time to think about it, and get me some new drawings."

Fang Xiang already knew where the problem lay.

It’s just that the pictures he drew were too advanced.

Beyond the industrial and material limits of this era.

The original new technologies were developed step by step and applied step by step.

He took it out one step ahead, but did not give them the production and synthesis data.

This results in only results but no process.

It's like giving you a tram produced in 2000 in the year 2024.

Look at this car, it's beautiful and has high technological content.

I don't think it's that difficult. It can be made by just standing on tiptoe.

However, when they actually started to make it, they found that many of the parts could not be made at all.

This is the result without considering the electrical part.

It is now the 60s, but the WP-7 drawings Fang Xiang provided are from the 80s.

The materials and processes of many of these components have been improved step by step over the past decade or two.

I took it out just to show off my skills.

But I didn't expect that Professor Li would directly use it to make the finished product.

So, it is not surprising to encounter such a problem.

But there is no way. Professor Li is right. I have to fill the hole I dug myself.

Wang Jinyang took Fang to the guesthouse and booked a suite.

I went back to sleep.

Fang Xiang was left facing a pile of blank drawings.

Okay, time to draw again.

Fang Xiang shook his head helplessly.

Since the ultimate form from the 80s is not usable.

Then it should be okay for me to draw the advanced forms of the 70s, right?

Fang Xiang began to review in his mind the drawings he had seen when he was in school.

It has to be said that in the past 20 years of development, there have not been many overall changes to the WP-7.

Most of them are small-scale improvements.

And it's more for durability.

When an engine is born, its life span is generally only about ten to twenty minutes.

In many cases, the lifespan is only a few minutes or even tens of seconds.

After constant repair, correction and improvement.

It only became barely usable, and then with the development and progress of technology, and the continuous adjustments made by scientific researchers.

The lifespan of aircraft engines will gradually increase to hundreds or thousands of hours.

So sometimes when you look at many Boeing engines, they are often based on technology from the 8s to 90s.

It may seem backward, but on the contrary, it represents a product that is extremely mature and commercialized.

I really want to give you a new engine from the 10s or 20s.

You may not dare to use it.

It’s because new products always have all kinds of inexplicable problems here or there.

I don’t know how many days I spent painting while Fang Xiang was bored in the guesthouse.

From time to time, you would see Professor Li bringing all kinds of strangers to visit.

Finally finished drawing the advanced form of WP7.

Most of the changed locations happen to be the ones marked by Professor Li before.

Looking at the stars outside the window.

Fang Xiang sighed.

Sure enough, leapfrogging into high technology comes at a price.

This bend is not so easy to pass.

Basic science and basic mathematics, these two big subjects, must have a solid foundation.

Only then can the road ahead be smooth.
