Chapter 1924

Quiet!

Dead silence!

Just at the moment of Bai Hang's voice falling, the whole classroom suddenly became quiet.

Everyone looks at Bai hang in a daze.

Honeycomb?

To tell you the truth, Chen Qiangsheng and others never thought that Bai hang would answer like this.

Of course, not only does Chen Qiangsheng not know, but also Qin Luo is very puzzled.

"I'd like to know why..." Without waiting for Qin Luo to speak, Chen Qiangsheng has already taken the lead in asking questions.

Yes, he would like to know the reason. He would like to know why Bai hang suddenly proposed the concept of honeycomb.

"Chen Bu, in fact, the reason is very simple. Since we can't replace the materials, we can only focus on reducing the weight of the raw materials."

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

To be honest, Bai hang did not answer his question directly.

Hearing Chen Qiangsheng's words, Bai hang smiles and says, "in fact, it is more appropriate for Professor Qin to explain this issue. However, since Professor Qin has given me this opportunity, I can only make a fool of myself."

"First of all, the honeycomb is a hexagonal building structure. Secondly, it has the highest degree of tightness, the simplest material required and the largest usable space."

"This can also maximize material savings and reduce the weight of the entire body."

The structure is stable and the weight is reduced to the greatest extent, which is why baihang chose the honeycomb shape.

Does it make sense?

Chen Qiangsheng thinks that there is a little truth.

But there is another problem.

That is, after reducing the material, the arrow can still maintain enough strength.

After all, a rocket is not an ordinary plane. The friction force it will suffer in the process of taking off will be several times, or even tens of times, of an ordinary aircraft.

Not enough strength, let alone fly into space, even the atmosphere can not be broken!

"I have one more question!" After a moment's silence, Chen said.

"Chen Bu, please."

"I don't prevent you from streamlining materials, but how can you ensure that after the materials are reduced, you can maintain enough strength to make the rocket launch smoothly!" Chen Qiangsheng said with a serious face: "strength is the foundation of our body. We can't throw away watermelon just for sesame."

As a saying goes, as long as the foundation is firmly built, we can build as high as we want.

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

Hearing Chen Qiangsheng's words, Bai hang smiles. He doesn't reply in a hurry. Instead, he looks at Qin Luo with burning eyes: "Professor Qin, are you coming or me coming?"

Ha ha

I'd like to come, but what can I bring!

"Forget it, just say it..." Qin Luo smiles and says.

"Yes, this question is too simple. It is reasonable that Professor Qin is too lazy to answer it." Bai hang sighed, then turned to Chen Qiangsheng and said, "Chen Bu, you don't know something."

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

"In my imagination, the sandwich layer of this structure is composed of metal materials, glass fiber or composite materials. The upper and lower surfaces of the sandwich layer are bonded with thin surface plates. The honeycomb structure formed by these materials has higher strength and stiffness than other sandwich structures, and the structural strength can be increased by at least 15% - 30% compared with riveted structure." Bai hang said seriously.
