Chapter 1903

Shake your head? Wait, what does that mean?

Don't believe me? .

looking at Bai Hang's expression, Qin Luo's mouth twitched wildly.

To tell you the truth, this drawing is really his. Although he did not draw it by himself, he always drew it.

"Cough, Professor Bai, you may not believe it. This design is really mine." Qin Luo said with a smile.

Bai hang???

He couldn't believe his ears.

Is this guy really drawn by Qin Luo?

To be honest, he didn't really believe it.

Qin Luo, when did he have research on space science and technology?

"Professor Qin, is that true?" Bai hang clenched his teeth and opened his mouth.

"More true than real gold..." Qin Luo nodded earnestly.

Bai hang:

I don't know, why, his heart always has a kind of sun dog feeling.

Nima, Qin Luo's hand is a little too long, right?

Want to get involved not only in mathematics, physics, but also in aerospace?

To tell you the truth, Bai hang couldn't believe Qin Luo's serious expression!

"Hoo Hoo Hoo..." After a long breath, Bai Hang's small heart gradually calmed down.

His eyes focused on the design drawings in his hand.

He wants to see what kind of shocking drawings Qin Luo can design!

Indignantly, he glared at Qin Luo, and Bai hang unfolded the drawing and laid it on the table to examine it seriously.

One minute, two minutes, three minutes

For more than ten minutes, Bai hang didn't say a word. It's not that he doesn't want to say it, but that he doesn't know what to say.

This guy, the whole design is almost perfect, even if he draws it, it can't be better than this.

"Three auxiliary thrusters, one main thruster, why is this..."

"Adopting double combustion chamber to improve combustion efficiency and increase thrust?"

“……”

Bai hang frowned and talked to himself.

Yes, he was puzzled by the things on the design drawing.

Including the layout of the propeller, including the design of the double combustion reservoir, these things are unprecedented, and there is no basis for him to refer to.

Can't understand, can't understand

After a long time, Bai hang looked up.

He fixed his eyes on Qin Luo and asked, "Professor Qin, you said that you drew this picture. Then I ask you why you want to use auxiliary thrusters. Isn't it better for four main thrusters to work together?"

Yes, it was one of his doubts.

It is impossible for the auxiliary propulsion force to be greater than that of the main propeller.

Why?

Qin Luo thought Bai hang had raised a very good question.

After sorting out his thoughts a little, Qin Luo said with a smile: "Professor Bai, there is a good saying that it is called energy conservation."

"As we saw just now, the propulsion system of four propellers of the same power collapsed."

"The reason is very simple. The thrust force is too big, but the existing materials can't bear it at all!"

Yes, energy is conserved. When the thrust generated exceeds the material's bearing limit, the whole system will collapse instantly.

This is also the reason why the experiment just failed.

It is undeniable that Bai hang feels that Qin Luo's words are a little bit reasonable.

But this does not mean that he agrees with Qin Luo.
