Quiet!

Deathly silence!

As soon as Bai Hang's voice fell, the entire classroom fell silent.

Everyone looked at Bai Hang blankly.

honeycomb?

To be honest, Chen Qiangsheng and others never thought that Bai Hang would answer this way.

Of course, not only Chen Qiangsheng didn't know, but Qin Luo was also very puzzled.

"I really want to know the reason..." Chen Qiangsheng had already taken the lead to ask questions before Qin Luo could speak.

Yes, he wanted to know the reason. He wanted to know why Baihang suddenly proposed the concept of honeycomb.

"Bu Chen, the reason is actually very simple. Since we can't replace the materials, we can only look at reducing the weight of its raw materials."

"Professor Bai, you did not directly answer my question, I want to ask why it is a honeycomb!" Chen Qiangsheng asked with a slight frown.

To be honest, Bai Hang didn't answer his questions directly.

Hearing Chen Qiangsheng's words, Bai Hang smiled slightly and said, "In fact, Professor Qin is more appropriate to explain this question, but since Professor Qin gave me this opportunity, then I can only show my ugliness."

"First, the honeycomb is a regular hexagonal building structure, and second, it has the highest degree of tightness and requires the simplest materials and the largest usable space."

"This can also save materials to the utmost extent and reduce the weight of the entire body."

The structure is stable and the weight is minimized, which is why Baihang chose the honeycomb shape.

Does it make sense?

Chen Qiangsheng felt that there was indeed a little reason.

But there is another problem.

That is, after the material is streamlined, the arrow body can still maintain sufficient strength.

After all, the rocket is not an ordinary airplane, and the friction force it receives during its lift-off process will be several times, or even dozens of times, that of an ordinary airplane.

Without enough strength, let alone flying into space, even the atmosphere can't break through!

"I have another question!" Chen Qiangsheng spoke for a moment of silence.

"Bu Chen please speak."

"I'm not preventing you from streamlining materials, but how can you ensure that after streamlining materials, you can maintain sufficient strength to make the rocket lift off smoothly!" Chen Qiangsheng said with a serious face: "Strength is the foundation of our life, we You can’t throw away the watermelon for sesame seeds."

There is a saying that as long as the foundation is well laid, you can build as high as you want.

Strength is the foundation and the foundation of all development. Without strength, everything is empty talk.

Hearing Chen Qiangsheng's words, Bai Hang smiled. He didn't answer in a hurry, but looked at Qin Luo with fiery eyes: "Professor Qin, are you here or me?"

Ha ha ha...

I want to come, but what can I do!

"Forget it, let's talk about it..." Qin Luo said with a slight smile.

"Yes, this question is too simple, and it makes sense for Professor Qin to be too lazy to answer." Bai Hang sighed, then turned to Chen Qiangsheng and said: "Chen Bu, you don't know anything."

"The honeycomb structure in my mouth is more than just a pile of regular hexagons stacked together."

"In my imagination, the sandwich layer of this structure is composed of metal materials, glass fibers or composite materials. The upper and lower sides of the sandwich layer are then glued with thinner panels, and these materials are used. The honeycomb structure has higher strength and rigidity than other sandwich structures. Compared with the riveted structure, the structural strength can be increased by at least 15% to 30%." Bai Hang said seriously.
