c500 Discussing the issue of aerospace engines

The two most important parts of the interstellar mining vehicle are the brain-computer part and the two huge thrust engines behind it.

Liu Cong, the brain-computer chip, is not so worried.

The engine is the most important thing.

An ordinary interstellar mining vehicle itself weighs several hundred tons, plus more than twice its own weight, so the engine must have at least a thrust of more than 600 tons to make the interstellar mining vehicle move on the ground.

If the interstellar mining vehicle is to fly into the sky, it needs to sail at a minimum speed of 60 kilometers per second. This kind of thrust is far from enough.

Although it is easy to build a large engine, it is even more difficult to achieve the desired thrust and speed.

This is why Liu Cong said that it is very difficult to break through in technology.

The difficulty this time is much more difficult than that of the seventh-generation turbofan engine. There are even some materials that Liu Cong has never heard of. They need to be replaced with other materials, and the lifespan is far less than the original lifespan of the interstellar mining vehicle. .

However, as long as the interstellar mining truck brings back this kind of material, Liu Cong can mass-produce it.

“Mr. Zheng, our research and development this time is very difficult. Blue Star does not have the most important raw materials for making this engine.”

“This is something called gray metal, and its hardness and melting point can reach very high results!”

“This kind of material is only found on the moon. I only found out about this material through the lunar rock and soil they brought. I think this material can’t be used as the core part of the engine!”

“According to my preliminary estimate, this material can be used in the engine for 100,000 hours without changing. And if we use Blue Star’s best material at present to replace the gray metal, it will only have a lifespan of almost 5,000 hours. This It’s enough for our current development.”

Mr. Zheng said with some confusion, “Isn’t the material you mentioned just pure metal?”

“Yes, it’s pure metal.”

In fact, currently there is no other material better than pure metal on Blue Star.

This material was originally developed for use in graphene batteries. Liu Cong did not expect that this small material would have such a big effect.

He never imagined that this material would become one of the most important materials in the spacecraft.

Perhaps, the system has already made arrangements here.

“At present, this is the only best material I can imagine. Mr. Zheng, you have used this material yourself, you should know how powerful this material is.”

“Whether it’s hardness, ductility, or thermal insulation, it’s basically top-notch!”

Mr. Zheng strongly agrees with this point.

“Academician Liu, you are absolutely right. The first time I saw this pure metal, I was really shocked!”

“I have never seen a material with such good thermal insulation, and I have never seen a metal material with such all-round development!”

“I originally thought this was the ceiling. I didn’t expect that there is a space metal that is more powerful than this metal. It’s really because I am ignorant!”

Speaking of this, Mr. Zheng probably had some thoughts in his mind.

Looking at the behemoth in front of him, Mr. Zheng couldn’t help but sigh.

“For such a behemoth, its engine must also be extremely huge.”

“Moreover, it is very difficult to increase the thrust of such a huge aerospace engine to several hundred tons!”

Mr. Zheng’s worries are absolutely justified.

At present, the maximum thrust of Huaxia Aerospace Engine is only a few dozen tons. To reach more than 100 tons, multiple aeroengines must be superimposed.

The interstellar mining vehicle can only be equipped with two engines at the rear, and they are two very large aero engines.

In other words, Liu Cong and the others’ biggest problem currently is to increase the thrust of the two engines to at least three hundred tons, otherwise it will not be enough to drive the interstellar engine.

“Mr. Zheng, actually this is what I’m most worried about. It’s too difficult for us to achieve such a technological breakthrough at the moment.”

“So, we will immediately set up a professional team to develop this engine.”

“I believe that with our efforts, we will sooner or later achieve a breakthrough in such technology.”

Liu Cong’s eyes showed determination, and he was not defeated by the difficulties in front of him at all.

In Liu Cong’s eyes, as long as there is something in the data, there is nothing he cannot develop.

“Academician Liu, we are not fighting alone. All the R&D personnel at the aviation launch base are working hard. They also hope to realize this dream as soon as possible!” Academician Zhang echoed from the side.

Academician Zhang’s eyes are bright. He has been doing experiments with Liu Cong for so long, and he has never doubted Liu Cong’s ability.

In fact, he can now unconditionally trust Liu Cong’s choices.

Although he was resolute in his mission, there was no trace of despair on Mr. Zheng’s face, and his eyes were full of yearning.

As far as he was concerned, when he resigned as the dean of the China Aviation Research Institute, he had already looked down upon everything.

No matter what the result is, he will also draw an end for himself.

“Okay, don’t think too much, just take me to visit the workshop first!”

Mr. Zheng took the initiative to ask the two of them to accompany him in for a look.

“Okay, teacher, I’ll take you in now to have a look.”

“Let me tell you, the scale of our research institute is much larger than that of your research institute over there!”

With that said, Academician Zhang led his teacher inside.

…………

…………

At noon, Academician Zhang took Mr. Zheng and Liu Cong to the cafeteria. In the afternoon, he continued to take Mr. Zheng to familiarize himself with the aviation launch base.

After the introduction of the two people, Mr. Zheng finally became familiar with this place.

Finally, at the request of Liu Cong and Academician Zhang, Mr. Zheng became the chief engineer of this project.

Seeing that it was getting dark, Liu Cong didn’t plan to go back tonight.

Before that, Liu Cong had already prepared a house for Mr. Zheng in advance.

This is a three-story house, with an area of ​​about seventy or eighty square meters on the first floor.

Liu Cong considered Mr. Zheng’s inconvenience, so he arranged Mr. Zheng on the first floor, while he and Lieutenant General Li Hu were on the second floor.

“Mr. Zheng, we will be neighbors from now on!” Liu Cong said with a smile.
