Chapter 129 The person who just walked in was the professor of medicine who invited Shen Zhe to the medical seminar.

He frowned slightly.

Looking at Shen Zhe suspiciously.

I don’t know the current situation.

The professors sitting in the front row couldn’t help squinting their eyes.

Looking at Shen Zhe with interest.

at this time.

A professor stood up.

“Mr. Shen, what do you think is the most important thing in the engine?”

The professor expected Shen Zhe to make trouble.

I didn’t expect Shen Zhe to answer at all.

Just want to embarrass him.

Let him retreat.

What’s more, this view was originally put forward by Shen Zhe himself.

Anyone can say anything against it.

But if you want to be convincing, it depends on the person’s ability.

If you don’t have the ability?

He will personally bombard people.

Shen Zhe moved, slowly taking a step forward.

As he walked towards the stage, he said, “This classmate is right. The rocket engine is like an inflated balloon. The material requirements are very high, so the material is very important…”

Shen Zhe hasn’t finished speaking yet.

The classmates on the stage snorted softly, “Look, you also said that it is important, so what is there to refute? I think you just want to sensationalize?”

“Heh.” Shen Zhe sneered.

The classmates on the stage were taken aback, “You said it yourself. The material is very important. Is there any difference between this and the point of view I said?!”

Shen Zhe shook his head, “The difference? It’s big!”

He frowned slightly.

I don’t understand what Shen Zhe wants to say next.

The professors were suddenly curious.

The teacher on the side looked slightly angry.

Shen Zhe slowly said, “You said that the most important thing is the material, have you forgotten that there is another thing called a gaseous working fluid.”

Gas working medium? !

Although most of the people sitting here are not students of aircraft power engineering.

But most of them are science students.

They also know what the gas working medium is.

This may indeed have something to do with the rocket engine.

But in the eyes of their non-professional students.

It doesn’t seem to matter much.

Shen Zhe continued, “The gaseous working fluid is a medium that can realize the mutual conversion of thermal energy and mechanical energy called working fluid, such as water vapor.” ”

At this time, the teacher’s brows were even more frowned.

He couldn’t help but said, “We all know these. After all, the people sitting here are all science students from Blue Bird University. You don’t need to talk about the meaning of gaseous working fluid! If you can only say the meaning of gaseous working fluid, then No need to continue.”

Shen Zhe ignored him and continued, “The ideal gas state equation is PV=nR, and the pressure established by the combustion chamber of the rocket engine is the condition that drives the rocket engine. Therefore, the necessary condition for the operation of the rocket engine is: gas Working fluid, build pressure in the combustion chamber…”

Many people present are not students of aircraft power engineering.

Come to the seminar to increase interest.

Confirm the postgraduate entrance examination goal.

But never expected.

Shen Zhe suddenly overturned the senior’s theory they had always believed in.

Hear what Shen Zhe said.

Everyone was shocked.

Is Shen Zhe right?

wrong! impossible!

Shen Zhe did not study this major.

How could he know!

Do not believe!

Everyone looked at Shen Zhe and the seniors on stage in disbelief.

“real or fake?”

“Is Shen Zhe right?”

“It seems to make sense.”

“We haven’t learned it again, we don’t know either!”

“To be honest, because I don’t understand this knowledge, it feels right to hear everything, but the premise is to say whether the people of these theories are professionals or not, Shen Zhe is just a director, a part-time pharmaceutical director!”

Most students don’t believe it.

But at this time, the eyes of the professors were bright.

Whether it is professional knowledge or professional terminology.

Shen Zhe is really good!

The senior who has been standing on the stage has a pale face.

He held the microphone and gritted his teeth and said, “You… what proof do you have! The proof that gaseous working fluid is the most important thing! No example is useless!”

Shen Zhe smiled.

I knew he would ask what could prove to support this argument.

Shen Zhe did not rush to say either.

But slowly stepped onto the stage.

Reached out his hand, “Give me the microphone.”

The senior was taken aback.

He squeezed the microphone in his hand.

If the speaker is handed over.

Then the dominance of the next discourse rests on Shen Zhe.

He is unwilling.

But there is no way.

The teacher in the audience urged, “Here it is, and listen to what other tricks he can tell.”

The senior reluctantly handed over the microphone.

Shen Zhe took the microphone and said, “The best example is the combustion of aluminum and oxygen.”

The combustion of aluminum and oxygen? !

Hear here.

The professor in the audience was slightly startled.

The teacher frowned.

The medical professor who had been standing at the door took a deep breath.

Although he studied medicine.

But chemistry is also exposed.

After all, those who study medicine have to be exposed to science knowledge.

Everyone was quiet at this time.

They want to know what else Shen Zhe can say.

Research professors also looked at Shen Zhe with great interest.

Shen Zhe continued, “¨ˇAccording to the conventional aluminum-oxygen combustion 4Al+3O2=2Al2O3, through this formula, the aluminum-oxygen combustion speed chart drawn, it can be seen that the equivalent exhaust velocity of aluminum-oxygen combustion is the highest. When the oxygen-fuel ratio is high, and almost 75% of the combustion products at this time are oxy-aluminum combustion alumina accounts for only about 20%, because the formation of thrust to high specific impulse requires gas working fluid to convert the internal Can reach kinetic energy.”

“If a rocket is to be successfully launched, a good engine is indispensable. The material of the engine is important, but at the same time, the fuel and gas working medium are also very important.”

Shen Zhe finished.

The whole place was quiet.

No one made a sound.

Even the teacher who had been blocking Shen Zhe was speechless.

The students in the audience were all stupid.

Why is it so quiet?

Where’s the teacher?

Why didn’t you kick Shen Zhe out?

What about the professor?

Why don’t you speak (the king’s)?

Where’s the senior?

Why not refute it?

Is Shen Zhe all right?

“well said!”

Sudden.

The professor who had been sitting in the middle had never said a word stood up.

Then applaud.

“Flap!”

The professor’s applause made the students who had been in a state of doubt instantly bewildered.



Are these theories mentioned by Shen Zhe okay?

Although my heart is full of doubts.

But still applauded.

The applause rang throughout the classroom in an instant.

Just at this time.

Suddenly another person appeared at the door.

After seeing the professor at the door.

Suddenly I became anxious.

“Oh, professor, why are you listening to the technology seminar, come back with me, our medical seminar is about to begin! By the way, where is Shen Zhe?”

Hear the voice behind him.

The medical professor pointed to Taishang County.

“where.”

“???”.
