Who do you think it is......

It turned out to be an old man with fluffy hair.

There is a very conspicuous rosacea. With reading glasses. I feel like I'm at least seventy years old.

The point is that when he walks, he still has to use crutches.

"Who?" asked Wang Bu'an curiously.

"Fu Wen'ou, Mr. Fu," Shangguan Yuqiang introduced in a low voice, "328 Research Institute." ”

"What do you do?"

"Helicopter research. ”

"Oh. ”

Wang Buan nodded.

Dare to love others is engaged in professional research.

No wonder they are not convinced.

No wonder they are coming to their own trouble.

In other words, I should be considered a halfway monk.

Others have been doing it for most of their lives, but how long have you been doing it? A few months? I'm afraid you haven't been doing it for a few months. It's strange for others to obey you.

You stinky boy, why should I listen to you?

The person who established the White Feather Whale Technology Company probably deliberately gave himself a little bit of power.

Okay, come on!

Lao Tzu is waiting for you to challenge.

And what about the old guys?

I got so hard that I beat even the old guys.

For the old disrespect, the same should be beaten.

"Huh, who are you two, and why are you here?" said the old man, surprised.

"I ......" Wang Buan stopped when he wanted to speak.

"This is Mr. Wang Buan. Shangguan Yuqiang hurriedly introduced.

"What for?" said Rune's brow.

“……”

Wang Buan was speechless.

This is...... Is this also called a company?

I don't even know the name of the chairman and general manager?

Or is the company set up in a hurry and there is not even a meeting?

It's basically equivalent to a passer-by saying hello?

"He is the chairman and general manager of White Feather Whale Technology. Shangguan Yuqiang said slowly.

"What is that?" said the old man, still not understanding.

"It's your biggest boss. Gives you funds. to your personnel. Give you technical support. ”

"Oh. I understand. ”

The old man suddenly realized, and then quickly took out a pile of information.

It's a thick, thick pile of information. All are sixteen-carat drawings.

Some of the drawings have very complex calculations. It's written in pencil. There are still traces of alteration in many places.

According to preliminary estimates, this should be the most original design draft. It hasn't been reviewed yet. And it's not stereotyped.

A similar design draft will definitely be turned upside down.

Maybe the final product, and the current drawings, are not even 10% in common.

Do what?

It's all handed over to Wang Buan.

Ask him to review it.

As the name suggests, it is an audit, but in fact, it is a disguised examination of Wang Buan's technical level.

Wang Buan took it quietly.

Boy.

All of this is technical information.

The vast majority is about aerodynamics.

Among them, some of the rotational airflow involved overlapped, canceled, disordered, and interfered with the calculation, which can be said to be incomprehensible.

There is no precedent for these things.

Someone else, Boeing, will not make this data public.

Bell Helicopter is even less likely to leak secrets.

All the data needs to be calculated and explored by yourself. If you want to take shortcuts, it's hard, it's hard.

The appearance of the tiltrotor can be copied. But the key technology can't be copied.

The 328 Research Institute is specialized in tiltrotors.

Now, all his personnel have been transferred to the White Feather Whale Company.

As the director of Research Institute 328, Rune Ö is now in charge of a laboratory. The only research mission is still tiltrotors.

The difference is that, in the past, it was the state that allocated research funds.

Now it's Wang Bu'an who pays.

True, everything has changed.

Now it is Wang Bu'an who is in charge of the project.

Rune Ou needs funds, talents, and raw materials, and they all need to apply from Wang Bu'an.

No wonder he has a lot of complaints.

If you're not careful, you want to find someone to vent.

In any case, he used to be a "state cadre". It's the emperor's food. Drought and flood protection. Stable work.

Now, it's a private company. Maybe it's going to go out of business at some point. The future is bleak.

Fortunately, the old man's emotions are well controlled.

found that Wang Buan was very young, so he didn't care about himself.

And young people are angry?

Bored.

"Mr. Fu, please. ”

"Nope. I'm busy. Notify me when you're done reviewing. ”

"There's no hurry, I'll only need five minutes. ”

"What did you say?"

"These aerodynamic calculations are not difficult. It only took me five minutes to get it done. ”

"You ......"

Rune Ou was a little confused for a while.

Five minutes?

Are you sure?

Are you sure you're not kidding?

You know, he's spent a lifetime studying these equations!

The research on tiltrotors actually began in the fifties and sixties of the last century. It's just that the technology has never matured. Research is also intermittent.

In the past, China was not yet open to the outside world, and it was difficult to obtain relevant information. It's all on your own.

Later, the reform and opening up introduced a lot of new technologies. The path of R&D has been a little smoother.

However, it is impossible to introduce key technologies.

In particular, the individual key data on aerodynamics are kept in high secrecy.

And the current conditions in our country, there is no way to calculate.

First, I don't know how to calculate it.

Second, the amount of computation is too large to consume.

Tianhe-1 is very powerful.

Tianhe-2 is also very powerful.

The light of Shenwei Taihu Lake is also very powerful.

There is certainly no problem with using them to calculate.

However, I can't afford to consume it!

The cost of one calculation is very high.

However, aerodynamics programs are very complex and unpredictable, and there is a lot of data to be calculated.

If you want to say that the biggest changes in the world, the first is the human heart, the second is the air, and the third is the flow of water. If you want to calculate it completely, the difficulty is even prohibitive for Tianhe-2!

Can Wang Buan do it?

Of course.

He's got Transformers to back him up!

With the computing power of a Transformer, what is a small aerodynamic?

The computing power of a robot elf is equivalent to countless Shenwei Taihu Lake Lights. The answer to the latter, which would take tens of thousands of years to calculate, can be completed in a matter of seconds.

Wang Buan was not polite, and directly calculated.

It seems that Rune's O didn't come specifically to trouble him.

Perhaps, the old man did have some emotions before. But after discovering that he was too young, the other party did not continue.

Respect the old and love the young. It is estimated that in the eyes of the elderly, he is still "young".

The requirements can't be too high.

He couldn't let Rune Ou underestimate him.

It doesn't matter if you slap your face or not. The important thing is to let the other party know that I, Wang Buan, am not here to eat.

I can gnaw on this messy company.

Especially on technical issues, I was able to beat all of you with just 0.001% of my brain.

There is no first.

Wu Wu is the second.

In front of professionals, you have to show your professionalism.

Otherwise, others won't look down on you. It's that they don't care about you at all.

"Come in. ”

"Good. ”

Wang Bu'an sat down silently.

Robot Elf No. 1 begins to calculate.

Robot Elf No. 2 begins to calculate.

Give the results directly.

If there is no result, give the formula directly.

In fact, these materials are all tiltrotor opportunities for a strange problem similar to drilling the tip of a bull's horn.

What's the big problem?

It's just that two cyclones interfere with each other.

It's strange that the same two rotors, if they are in tandem front and rear, are almost fine.

But if the left and right are connected in parallel, they will interfere with each other and weaken each other. In the end, it even led to a serious drop in lift, less than one-fifth of the standard requirements, and eventually led to a crash.

This problem has plagued tiltrotors for thirty or forty years, and it has never been solved.

Until now, the V22 Osprey can only be said to have improved. And not a radical solution.

Perhaps, one day, under special circumstances, the cyclone caused by the two rotors will weaken each other, and then the plane will fall straight down.

What is the root cause of this problem?

Airflow cross-cutting.

Disturbed airflow overlaps.

Stable air flow is similar to granite.

The rotors are in a stable airflow and can get plenty of lift. This is where the most basic lift of a helicopter lies.

However, if the air flow is disturbed, the granite will turn into shale and limestone.

The support is seriously insufficient. Lift will drop sharply.

How to fix it?

First, the best thing to do is not to connect left and right in parallel. Do not develop tiltrotors.

Second, remedies. It is the cutting layer that staggers the airflow.

Thirdly, a backup lift system.

Fourth, a backup injection system.

Obviously, the first one is impossible.

The second one is being done. The main method is to stagger the rotation frequency of the rotor. Or even fine-tune the angle of the blades. Minimize the mutual interference between the two rotors.

The third, Bell Helicopter is also working on it. There are already some effects. It can effectively prevent crashes.

The fourth, also has some ideas.

This shows that earthlings are still very smart.

They also thought of a lot of effective methods, but they didn't work very well.

For example, a backup lift system.

It's hard to lift an entire helicopter.

It can only be said that it is barely enough to avoid a rapid crash of the helicopter. Give the controller more time to adjust the aircraft attitude.

For example, tilting an airplane. Tilt back and forth. Left and right tilting, both may be cut out of the airflow.

The back-up jet system pushes the helicopter away from the special airflow environment.

The reasons for airflow cutting are complex.

There are inside and outside. The main thing is the airflow cutting caused by the rotor itself.

There are external. These include wind direction, wind speed, and rotor vibration, impact, scattering, refraction, sputtering, and more. Under certain special conditions, the airflow can be very disturbed.

And crashes, often occur in these special circumstances. It can be said that it is impossible to prevent it.

It's unrealistic to want to show it through all the formulas.

Unless there is a supercomputer simulation.

Wind tunnels can only simulate one-tenth of the conditions.

In other words, there are still 90% of the situations that cannot be simulated.

Or rather, something you can't imagine.

Nature is unpredictable, and no simulation tool can be perfectly presented.

A minute passed......

Two minutes passed......

Three minutes passed......

Rune Ou looked at the manuscript paper in his hand in a daze.

This Wang Bu'an, the action is really fast.

In just a few minutes, so many results were given.

This little guy doesn't seem to be simple!
