quiet!
Deathly silence!

The moment Bai Hang finished speaking, the whole classroom fell silent.

Everyone stared blankly at Bai Hang.

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

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

"I really want to know the reason..." Before Qin Luo could speak, Chen Qiangsheng had already asked the question first.

Yes, he really wanted to know the reason, he really wanted to know why Bai Hang would suddenly bring up the concept of cellular.

"Mr. Chen, the reason is actually very simple. Since we can't replace the material, we can only focus on reducing the weight of the material."

"Professor Bai, you didn't answer my question directly. I want to ask why it's a honeycomb!" Chen Qiangsheng asked with a slight frown.

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

Hearing Chen Qiangsheng's words, Bai Hang smiled slightly, and said, "Actually, it's more appropriate for Professor Qin to explain this question, but since Professor Qin gave me this opportunity, then I can only make a fool of myself."

"First of all, the honeycomb is a regular hexagonal building structure, and secondly, it has the highest degree of closeness, the simplest materials required, and the largest usable space."

"This can also save materials to the greatest extent and reduce the weight of the entire rocket 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 truth.

But here another problem emerged.

That is, after streamlining the materials, can the rocket body maintain sufficient strength.

After all, a rocket is not an ordinary airplane, and the friction it experiences during its ascent will be several times, or even dozens of times, that of an ordinary airplane.

Without enough strength, let alone fly into space, even the atmosphere cannot break through!

"I have another question!" Chen Qiangsheng said after a moment of silence.

"Department Chen, please tell me."

"I'm not stopping you from simplifying the materials, but how can you ensure that after reducing the materials, you can still maintain enough strength to allow the rocket to take off!" Chen Qiangsheng said seriously: "Strength is the foundation of our life. You can’t throw away watermelon just for sesame seeds.”

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

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

Hearing Chen Qiangsheng's words, Bai Hang smiled. He did not rush to answer, but looked at Qin Luo with fiery eyes: "Professor Qin, are you coming or should I?"

hehehe...

I want to come, but what to bring!
"Forget it, let's talk..." Qin Luo smiled slightly and said.

"That's right, this question is too simple, and it's reasonable for Professor Qin to be too lazy to answer." Bai Hang sighed, then turned his gaze to Chen Qiangsheng, and said, "Department Chen, you don't know something."

"The honeycomb structure in my mouth is not just a pile of regular hexagons."

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