don't call me singer

Chapter 1017

In Changcheng, He Shisong hurriedly ran out of the mobile building at the Helicopter Research Institute of the Aviation Group, and when he saw someone, he stopped and asked loudly, "Have you seen Xiaobai?"

"Has anyone seen Xiaobai?!"

"Has anyone seen Xiaobai?"

He Shisong was dying of worry, where did this kid go!

"Mr. He, isn't the test machine about to take flight? You are not watching at the scene, what are you doing here?" A graduate student who was held back by him was very puzzled.

"Test flight... What's the test flight? I'm afraid Xiaobai will dismantle my prototype...Xiaobai? Xiaobai!!!"

"Teacher, I just saw Xiaobai go to the test platform..."

"Fuck..." He Shisong swears and runs away.

After a while, He Shisong was seen carrying Gu Xiaobai and dragging him out of the test workshop.

"I'll take it apart...just take it apart, I promise to put it back..." Gu Xiaobai was like a puppet attracted by a magnet, his limbs stretched desperately towards the test platform, as if the room was magnetic .

"No, you won't! Last time you disassembled my No. 2 test machine, you didn't put it back!"

"That's because your design is unreasonable!" Gu Xiaobai said, "That design method is wrong..."

"That was designed by us for decades, what's wrong, it's the most advanced design now..."

He Shisong was about to cry.

Gu Xiaobai has been here for almost a week.

This week, the entire institute was almost turned upside down.

He Shisong knew Gu Xiaobai's attainments in acoustics, fluid mechanics, especially ship dynamics.

But he didn't expect that Gu Xiaobai knew so much about aerodynamics.

After all, acoustics and aerodynamics are things that come in the same strain, and Gu Xiaobai learned it too quickly.

The second day after Gu Xiaobai came, he gave He Shisong a formula to further improve the shape of the helicopter propeller blades on the basis of the saber-shaped propeller.

Two pages of thin paper in "The Design of the Radius of the Blade Edge and the Application and Calculation Formula of the Ultra-miniature Spoiler Comb" were thrown on He Shisong's face, and He Shisong knelt down directly.

After preliminary experiments, according to Gu Xiaobai's design, the noise of the blades can be reduced by 5 decibels without changing all the existing aircraft structures, and the lift can be increased by about 7%. Even the vibration of the fuselage, Both were reduced by 12%.

What do these data mean?
For ordinary civil aircraft, it is to improve comfort and reduce fuel consumption.

In terms of military use, the significance is even greater.

In most cases, helicopters will fly at low altitudes to avoid radar detection. Without radar, the human ear becomes the best early warning radar, and the noise of the helicopter is reduced by 5 decibels, which may allow the enemy to detect the helicopter. The time is tens of seconds or 1 minute.

Of course, He Shisong was mentally prepared for Gu Xiaobai's strength.

After all, Gu Xiaobai's strongest point is acoustics. To reduce noise and improve lift, for Gu Xiaobai, it's all in his field.

Although He Shisong was shocked by the technique of directly shaking his face, it was not unexpected.

Next, Gu Xiaobai proposed to study the mechanical design of the helicopter.

Although Gu Xiaobai is not from their research institute, for the inventor of the black square formula, a special consultant and partner of the Shipbuilding Group, it is really not a secret to participate in this level of research.

He Shisong and Gu Xiaobai discussed some issues in aircraft mechanical design.

From the discussion of turbojet to turbofan to turboshaft, I am deeply amazed at the depth of Gu Xiaobai's theoretical knowledge.

Listening to Gu Xiaobai discussing these theories, I feel that Gu Xiaobai is simply a master who has been immersed in machinery for decades.

Then, He Shisong got hotheaded for a while, and agreed to take Gu Xiaobai to see the independent large turboshaft engine he researched.

And then...he assembled the turboshaft engine he was planning to test run, and he suffered.

When he saw Gu Xiaobai standing in the middle of countless parts, like every obsessive-compulsive disorder, arranging all the parts to fill the entire factory, his heart almost twitched.

My experimental model!

Facts have proved that Gu Xiaobai is such a good acoustician and engineering theorist, but such a poor engineer!

No, it's not just bad, it's weird as hell.

No matter what kind of machinery, his dismantling ability is 100%.

But the reload ability is almost 0%.

He has disassembled so many things, whether it is complicated or weird, he can dismantle it.

But when pretending, he would always get into all kinds of strange entanglements, and then pretend to be a mess.

A bunch of extra parts?That's still easy!

After all, whether it is a turbofan or a turboshaft, its core is a turbojet. A large turbojet engine has tens of thousands of parts.

With these tens of thousands of parts, it is not a problem of one or two extra parts.

Many times, he would assemble the extra parts into gadgets that He Shisong didn't even know what they were, and then tried to put them back together in vain.

What makes He Shisong even more weird is that most of the time, he can really put it back on!
In the limited space where you can barely fit a needle, rearrange some limited parts and put them back together.

Is this something humans can do?
This is no jigsaw puzzle!

Sometimes, He Shisong wonders if there is a supercomputer in Gu Xiaobai's brain, which can perform almost infinite permutations and combinations.

What's even more weird is that after reading Gu Xiaobai's disassembly and assembly ideas, He Shisong felt that he almost didn't know how to install his own engine.

Every time he pretends to be pretending, he suddenly feels that what Gu Xiaobai said makes sense.

Then I forgot how to pretend.

He Shisong thinks this child is poisonous!So convincing!
However, the job of an engineer is not like this!
Just like the progress of the physics world, it is constantly innovating on the basis of other people's theories.

Every design in the engineering world is also based on the former and has been continuously improved for countless years.

Gu Xiaobai always has a big brain hole, wanting to bypass something, and then use another method to realize the idea...

That's right, Gu Xiaobai's ideas are all theoretically feasible.

But turning theory into reality is really not that simple.

In many cases, physicists can be hundreds of years ahead of engineers.

Therefore, the way of thinking of physicists really cannot be applied to reality.

From He Shisong's point of view, Gu Xiaobai is too whimsical, and there are too many castles in space.

For physicists, sometimes a thought experiment can lead to a theory.

For example, the twin paradox, such as Schrödinger's cat.

To some extent, physicists are also creatures that use their imaginations to eat, but their imaginations must be consistent with each other.

But for engineers, things that have not been verified cannot be used in actual products, because these things are for people to use and will kill people.

Moreover, the process of verification is not to write some formulas and conduct some experiments, but to invest a lot of money and time into it.

Because in the human world, there are errors, mistakes, and all other things that do not exist in the theory, which may lead to the failure of the experiment.

After these few days, He Shisong felt that he was going crazy.

Pan Guoxiang, this guy, what kind of disaster did he put on himself!
