Technology: The first development of a sixth-generation fighter

What a joke, if not already overcome the technical barriers.

How dare he Jiang Chen pretend to be forced on such an occasion!

The moment Jiang Chen’s voice fell, everyone was shocked, and all the researchers in the audience instantly exploded the pot!

“Sleeper! What a technical solution! ”

“This Nyima is also outrageous!”

“I am not cultured myself, and I am a straw in the world!”

“Have the courage to ask Professor Xiao Jiang, where did you come to develop so many solutions…”

“If these technical solutions are really feasible, then Professor Xiaojiang is also too good…”

“This is the legendary master of time management?”

“Professor Xiaojiang, always drip god!”

……

Jiang Chen looked at the conference hall that had exploded the pot.

Laughing and knocking on the microphone laughed:

“Guys.

Now is not the time for you to be shocked.

Next, the director of the department gave me a full twelve points of spirit.

Because then you will be the main force of listening to the plan.

If researchers in your department don’t understand the content, they will come to you for comparison.

So your pen and paper, the relics recorder can now be started!

If you or your researchers come up to me and ask me, I’ll call the guards back and throw you into the sea to feed the sharks!”

Understand??? ”

Jiang Chen’s voice sounded like an alarm bell into the hearts of various directors and scientific research personnel.

One by one, they opened their voice recorders.

Have a small book and pen ready to take with you…

Professor Xiaojiang’s words don’t look like a joke at all…

The escort and Luo Ganglin couldn’t help but smile as they watched the reactions of the people in the audience.

When they used to have a meeting.

There are all those sleeping below, and now Jiang Chen is coming.

All in good spirits!

Professor Xiao Jiang has something!

Jiang Chen looked at everyone and nodded with satisfaction.

Then I looked at a dozen technical solutions.

“Since we are all meeting for the first time.

I don’t know much about your knowledge reserves and technical level…

Then our technical solution will start with the simplest!

The first scenario!

“New Sonar System Based on Magnetostrictive Effect”!

Wake up, the sonar department’s attention!

Okay, let’s start sharing!

…………

I believe that everyone knows that the magnetostrictive effect refers to the effect of the reversible change of geometric size of magnetic substances due to changes in external magnetic field conditions during magnetization

The magnetostrictive smart materials mentioned in my scheme are actually a class of materials with strong magnetostrictive effects and high magnetostrictive coefficients.

That is, it is a class of materials with the function of electromagnetic/mechanical energy conversion to each other.

Magnetostrictive materials are generally divided into two categories: metal magnetostrictive materials and rare earth-iron (RFe2) supermagnetostrictive materials.

Since rare earth-iron (RFe2) supermagnetostrictive materials have much larger magnetostrictive values than traditional magnetostrictive materials, and have fast mechanical response, high power density, and high coupling coefficients…………”

Jiang Chen tirelessly explained the technical solution of “New Sonar System Based on Magnetostrictive Effect” on the stage.

The director and researchers of the sonar department below are in trouble.

Jiang Chen said so much.

They don’t even understand 20%…

Even if the department director is close to the level of academicians, he will understand the degree of 30-40%…

When Professor Xiao Jiang said something well-known, they were almost stunned.

Where is this well known?

Is Professor Xiao Jiang misunderstanding about the well-known ???

It is clear that only academicians such as Huang Shuxu and Luo Ganglin can understand whether it is good or not!

When Jiang Chen finished.

Director Deng, who was already forty years old, stood up, looked at the questions recorded in his small book and began to ask questions.

“Professor Xiaojiang.

We don’t understand the magnetic induction strength part of your plan very well…”

Although as an elder in his forties it is a bit humiliating to ask a junior question…

But compared to being thrown into the sea by Professor Xiaojiang to feed the sharks, he felt that it was better to ask clearly now.

Of course, everyone knows that Jiang Chen’s words are jokes.

It’s just that now I understand.

There is only good and no harm in the development of nuclear submarines!

Jiang Chen wanted to hurry, and they wanted to hurry up too!

After all, it is quite annoying to be annoyed that Bald Eagle’s nuclear submarine has been staying in the Western Ōhei Ocean Diss…

Jiang Chen smiled and looked at the Huang Shu preface:

“Elder Huang, I have just talked so much.

My throat is a little dry, you should be able to explain this question for you, right? ”

Although he is a guest expert.

But there are still etiquettes that should be understood.

Can’t force it all for him, right?

I have to let the two designers drink soup!

Huang Shuxu nodded his head with some complicated face and explained:

“I believe that magnetic induction intensity refers to the physical quantity that describes the strength and direction of the magnetic field, and everyone here should know it, after all, this is just common sense in middle school.

Therefore, the meaning of the formula that Professor Xiaojiang just made can be understood as:

Under the conditions given by the magnetic field, the magnitude of f is related to the direction of the charge movement.

When v is in or opposite a particular direction, the force is zero.

The force is greatest when v is perpendicular to this particular direction, which is Fm.

Fm is proportional to |q| and v, the ratio is independent of the moving charge, reflects the nature of the magnetic field itself, and is defined as the magnitude of the magnetic induction intensity, i.e..

The direction of B is defined as the direction in which the right hand spiral advances when the direction of Fm, the maximum force of the positive charge is shifted to the direction of charge motion v.

After defining B, the force of the moving charge in the magnetic field B can be expressed as F=QVB, which is the Lorentz force formula used to deline the magnetic induction density…”

Many theories that were originally understood by the R&D personnel of the sonar department gradually became clear under the analysis of Huang Shuxu.

But with the further dissection of Huang Shushu to about 70% of the plan.

Huang Shuxu also scratched his head.

The old man looked at Jiang Chen with a red face.

“Professor Xiaojiang.

Say it without laughing ha…

In fact, I don’t understand a lot about the deduction of the Lorentz force formula in your plan…

You see, can you talk about it again??? ”

Huang Shu’s preface said this.

The R&D personnel present were dumbfounded.

a chicken…

Good feelings, it turns out that they are not too dish…

It’s Jiang Chen who is so awesome!

Academicians of the two academies said that they did not understand some parts of Jiang Chen’s plan too well, so that their hearts were much more balanced…

Jiang Chen looked at Huang Shuxu, who humbly asked for advice, and smiled:

“Of course!”
