Wang Buan.

Wang Buan.

The name is unfamiliar.

Rune Ou had never heard of the name before.

How did he come out?

How did he get his knowledge of aerodynamics?

University?

No kidding.

There is no such course at any university.

Including MIT, Stanford, Tsinghua and other super science and engineering universities. None of them have such advanced courses.

Even at Boeing or Bell Helicopter, there are no more than 100 experts who can master these extremely advanced aerodynamics.

That's right, a hundred.

Maybe there weren't even thirty of them.

Only the best experts in the field, working as a team, can solve such a complex problem.

Unless it's the legendary superweapon manufacturer Cobra......

He shuddered.

Cobra......

The monstrous "Vulture Eagle" tiltrotor fighter.

"What's wrong with you?" Wang Bu'an sensitively sensed Rune Ou's mood change. This old man seems to be a little scared?

"Have you heard of Cobra?" said Rune's Or, cautiously.

"I heard. Thunderstorms, umbrellas, cobras. Three arms giants. Wang Buan said lightly.

"They secretly developed a Vulture tiltrotor helicopter that was said to be very advanced. Rune Ou said in a low voice, "But he has never been involved in actual combat. It is said to be for secrecy. ”

"What's the use of things that aren't put into actual combat?" Wang Buan said disdainfully, "Is it on paper?"

"Let's be careful. Rune Ou subconsciously looked around.

"How?"

"I heard ......"

"What did you hear?"

"I've heard that Cobra has a monopoly on the latest tiltrotor technology, and anyone who wants a piece of the pie in this area will suffer a merciless blow. ”

"Really?"

Wang Buan shook his head casually.

It's just a rumor.

Not really.

This is China.

What mercenaries, what killers, it's not popular here.

In foreign countries, many arms giants can indeed do whatever they want, kill people and sell goods, become lawless, and even provoke wars large and small.

However, in the territory of China, it is impossible for them to be so arrogant and domineering.

Come one, kill one.

Come two, kill one.

It is almost impossible to make waves in China.

If you want to monopolize the tiltrotor helicopter market, it is even more impossible. Who is he, Wang Buan? Will he be afraid of Cobra? Just kidding......

It is true that Cobra must have a lot of high technology in its hands.

However, he Wang Bu'an is not bad!

Behind him, Wang Bu'an, is the planet Cybertron.

No matter how powerful the Cobra company is, it is also a native of the earth, is it good?

"Sir, let's move on to technical issues. ”

"Okay. ”

"You may be seated. ”

"Okay. ”

Rune O calmed slightly.

He struggled to bring his messy thoughts back.

The turbulence generated by the rotor is a very unpopular area of research. Outsiders will hardly know about this field.

Ordinary fixed-wing aircraft do not need it.

Ordinary single-rotor helicopters are also not needed.

Ordinary front and rear tandem twin-rotor helicopters are also not needed.

A very peculiar phenomenon. Like Chinook, a tandem tandem, twin-engine, twin-propeller helicopter will not have the problem of airflow interference.

Only this tiltrotor aircraft, juxtaposed with two wings, will have this fatal flaw. It's distressing.

Neither Boeing nor Bell Helicopter has been able to solve this problem.

Now the problem is here, and Rune O can't solve it.

So, can Wang Buan solve it?

"You ......," Rune Ou said again.

"There is no cure. But it can be avoided. Wang Buyan replied indifferently.

"How to avoid it. ”

"Add an emergency lift assist system. ”

"Lift amplitude?"

"One hundred percent. ”

"How?"

"Jet of air. ”

"Oh. ”

Rune O's sensed something was wrong.

Is it just an air jet, and how does an air jet support a weight of tens of tons?

If it's a super-large tiltrotor aircraft, it may weigh more than 100 tons. This is not a fighter jet. It is not even a frivolous carrier-based aircraft. The weight is very heavy.

If the auxiliary lift system is only used for emergency relief, it only needs to be more than 30% of the standard lift.

However, Wang Buan actually came up with an astonishing number: 100%.

I said, are you serious?

You don't don't understand anything, just talk nonsense, right?

Tens of tons of lift, 30%, that's more than ten tons. This in itself is not easy to achieve.

The V-22 Osprey is equipped with an auxiliary lift system, which is only 5 tons.

The experimental V-44, which required an auxiliary lift force of more than 10 tons, has never met the standard.

Why did you outrun the V-44?

You know, that's the result of twenty or thirty years of research and development by others!

Unless it is a Vulture tilt wing that has been kept under secrecy, it is possible that it has met the demand in terms of auxiliary lift.

"Why, don't you believe it?" Wang Buan didn't raise his head.

"When we do scientific research, we must seek truth from facts. Rune Ou said in a deep voice.

"Look at this. ”

"What?"

Wang Buan threw the drawings of the 126 aero engine to the other party.

After reading it carefully, Rune Ou immediately changed his attitude.

Enough is enough.

It's just more than enough.

There is a jet stream of 126 aero engines, and there are no problems at all with auxiliary lift.

As for the high cost, we will talk about it later.

"Look at this again. ”

"Good. ”

Wang Buan handed the drawings of the turboshaft engine to the other party.

After reading it, Rune Ou's face became even more serious.

He refused at first.

10,000K power output? Just kidding......

What kind of turboshaft engine has such terrifying power? Even the engine of the largest and heaviest Mi-26 helicopter does not have 10,000 K!

Wang Buan won't be preparing to release satellites, right?

In other words, in the field of science, this is the most taboo.

Without paying attention to scientific reality, desperately piling up parameters, the result could not be changed in the end, and it could only be dismissed.

The most typical example is the original turbofan 6 aero engine.

The cowhide is blown up, and there will always be a day when it will break.

Wang Buan, is this going to follow in the footsteps of Turbofan 6?

However, after taking a closer look, Rune Ou gradually calmed down again.

No problem.

At least there are no problems with the drawings.

The combustible hydrogen engine designed by Wang Buan can indeed reach 10,000K. It even exceeded the standard a little.

The only question is how combustible hydrogen comes from. How is it translated?

It is not explicitly stated in the drawings. Technical secrets for sure.

Rune Ou is also very sensible. Didn't ask.

Unless Wang Buan took the initiative to explain, he would not take the initiative to ask.

When it comes to core secrets, those who should be avoided must be avoided.

"Single-shot, single-shaft?"

"Nope. Single-shot biaxial. ”

"How is the power distributed?"

“334。 ”

"Not 442?"

"It's not. It's 334. ”

"Oh. ”

Rune Ou nodded slowly.

Wang Buan's persistence made him feel the confidence of the other party.

The so-called 334 is the left and right rotors, each occupying 30% of the power. The remaining 40% is used as reserve power.

This layout is also problematic. It's special. Other tiltrotor aircraft, all of which are 442 layouts. That is, the two rotors each allocate 40% of the power. The remaining 20% of the power is used as a reserve.

Other tiltrotor aircraft are twin-engine and dual-axle. One engine controls one rotor. It's easier to arrange. The manufacturing cost is lower.

However, Wang Bu'an had to use a single engine to control two rotors at the same time.

In this way, the problem arises.

How is the power distributed?

How to reconcile the balance?

Where is the engine located?

The engine of the V-22 Osprey is mounted under the rotor. It is directly connected to the rotors.

However, according to Wang Buan's intention, the engine should be placed in the middle and installed in the fuselage. As a result, there will be an impact on the layout of the fuselage. Thus affecting the transport space.

Rune O prefers to be double-shot and dual-axis.

After all, this is a ready-made experience. You can learn it directly.

It's not the details.

This is a fundamental structural issue.

He had to ask clearly. Otherwise, the study cannot be carried out.

Wang Buan has more drawings.

Sketches, of course.

His sketches are very peculiar.

The engine is on top of the fuselage and is connected directly to the rotor with a drive shaft.

At the same time, the engine also has a jet device, which can provide auxiliary lift by jetting directly downward.

Strictly speaking, it is a fusion of the characteristics of three aircraft.

First, fixed-wing aircraft.

Second, vertical take-off and landing.

Thirdly, gyroplanes.

A single engine can do everything you need.

It's just that in this way, the requirements for the engine are very high. It can't be the slightest flaw.

If you are equipped with two engines and one of them fails, the other can still continue to control the aircraft and land safely. There are generally no major surprises.

However, if there is a problem with a single engine, it is a crash.

If Wang Buan wants to be foolproof, he must produce it himself.

It is absolutely not safe to hand it over to others.

Turbofan engines?

Turbojet engines?

Turboshaft engines?

I'm afraid that these three are already mixed together.

With such a complex manufacturing process, it is estimated that other equipment cannot be manufactured except for the robot elf.

This is the original intention of Wang Buan's basic design. As much as possible, the manufacturing work is done in your own industrial park. There is no need to resort to other people's hands.

The core technology should still be in your own hands.

Leave the work that the engine can do to the engine.

Actually, it also means that ninety-nine is one.

The flying saucer in the future is a circle. There is no need for any special shape at all.

Because it's got plenty of power!

As the old saying goes, as long as there is enough power, a single brick can go out through the endless starry sky and reach the planet Cybertron.

The reason why current flight technology requires a wide variety of shapes is nothing more than a lack of power.

When the power is sufficient, everyone's design will be about the same.

"Lao Fu, you're really fast, why don't you wait for me?" Suddenly, a rude voice came from the elevator entrance.

"It's Dr. Runas. Shangguan Yuqiang said in a low voice.
