This civilization is very strong, but the technology tree is a bit crooked

Chapter 28 Drones bring local specialties - scaring people to death

After getting into the car, Chen Yi hugged his laptop and looked at the white-haired old man next to him.

"Master, you should not be an investigator, but a professor, right? May I ask your surname?"

"An unknown old professor, not worth mentioning."

Seeing Chen Yi's nervousness, the old man smiled and said, "Mr. Chen doesn't need to be so nervous.

This time it's just me, an old man, seeing your Yifei's moon landing drone, and I want to know some questions.

It's not here to guide the work, and it's not to impose any restrictions on Yifei.

On the contrary, you Yifei are doing very well.

Through these several live broadcasts, the scientific and technological spirit of our people has been well promoted.

Announce to the world that our people also have great knowledge, great knowledge, and great technology.

There is SpaceX on the other side, and there is Max.

We also have a family called Yifei, which has a genius like Mr. Chen. "

There are so many official words, it's hard to believe that you just came here to understand the problem.

Chen Yi, who had not just graduated from Xiaomengxin for a long time, couldn't help complaining in his heart, but on the surface he pretended to breathe a sigh of relief.

"If the professor has any questions to ask, I promise to know everything and talk endlessly."

The professor nodded, without sloppiness, and went straight to the topic: "The moon landing drone that just flew by the wing, used a rotary detonation engine, right?"

"Yes, the fuel loaded by the UAV is limited, and it is difficult for ordinary engines to enter the orbit of the planet, let alone land on the moon.

I sprinted into space live for the first time before. I tried the combination of a turbojet engine and a rocket engine, and brought an oxidizer. I found that the specific thrust was much worse, and it was difficult to complete the moon landing.

Afterwards, it was changed to a rotary detonation engine with a self-supercharging effect and a larger specific impulse. "

Chen Yi explained bluntly.

Except for adjusting and upgrading the system, and replacing it with its own manufacturing, there is no other concealment.

"Rotary detonation engine, this is the main direction of the next generation super engine.

Many countries, including us, are still in the laboratory stage across the ocean.

Unexpectedly, Yifei has already come up with a mass production plan for a technology that has not been broken through by so many countries, which is amazing. "

Speaking of the latter, the professor revealed a deep sigh.

When Chen Yi heard this, he immediately expressed his opinion.

Said that this is just a technology he developed by chance.

Since the country needs it, after a while, he will sort out the relevant data and send it to the professor and hand it over to the country.

Faced with Chen Yi's enthusiastic statement, the professor was also taken aback, and then shook his head.

"It's not necessary to hand in.

This is a technology developed by you and Yifei, and the country will not take personal research results.

For this rotating detonation engine technology, a patent compensation will be paid according to the value. "

After the professor finished speaking, he asked Chen Yi some technical questions, including some technical formula principles.

It seemed that he really came to ask a question and not have other things.

For these questions, Chen Yi accepted them all.

Say what you understand, and admit that you don’t understand if you don’t understand.

For the rotary detonation engine, he also explained some key structures, as well as some technical points based on the actual research of the lunar landing drone.

Involving engine manufacturing, aircraft manufacturing, aerodynamic layout and other technologies, Chen Yi had an in-depth discussion with the professor.

Such discussions and chats lasted for more than three hours.

It wasn't until several board-inch youths came back with packed dinners that the two of them stopped discussing.

"Xiao Chen, I'll send you an application when I go back. If I have time, I will come over to take classes, read direct blogs, and help you improve your basic knowledge.

Although you have deep research in the fields of rocket aerospace, aircraft manufacturing, aerodynamic layout and so on.

But your foundation is too poor, you still need a good tutoring. "

The professor picked up a boxed lunch, and he didn't dislike the simplicity of the food. While eating, he put forward his own suggestions to Chen Yi.

As an academician-level figure in the field of aircraft, I spent more than three hours discussing and chatting.

The professor discovered that Chen Yi was a real genius.

In the fields of aircraft design and manufacturing, engine manufacturing, and aerodynamic layout, he surpassed most of the professors.

Some technical details are unheard of, unseen, full of unconstrained feeling.

But if you think about it carefully, it perfectly fits the data and theory, and it will be no problem to switch to the sixth-generation fighter that is under development.

However, in many basic fields, such as the basics of aerospace, mathematics, and physics, Chen Yi lacked a lot, and he was only at the excellent level of an undergraduate.

These basic deficiencies and partial subjects will undoubtedly affect Chen Yi's subsequent development and waste Chen Yi's talent.

This makes some professors who love talents really feel a little bit unbearable.

Chen Yi, who was eating, stopped and raised his head.

"Professor Er, I only have a college degree, and I haven't upgraded from a college to a bachelor's degree.

It’s been five years since I graduated, so it’s a little bad to go back to direct blogging, isn’t it? "

Chen Yi shook his head, and declined the proposal to go back to study.

Go back to study?

joke.

It has been five years since he graduated and started his business for more than four years.

I have long been used to the boring life of being a boss, how can I get used to it when I go back to study.

And when I go back to campus, I have to go to class every day, and there are a group of classmates around me.

It is difficult for him to engage in some black technology, and if he is not careful, he will be watched by the crowd.

"Direct doctorate, not undergraduate."

"At that time, apart from doing some projects with me and learning to supplement your basic knowledge, the rest of the time will be relatively free."

Professor Zhang explained.

"Forget it, I'm not used to going back to school after graduating for so long.

I can also self-study the basic knowledge. It is enough for the professor to recommend me some book lists and bibliographies. "

Chen Yi waved his hand, but still chose to refuse.

"Fine.

When I go back, I will send you a catalog of book lists and documents, and you can study and supplement by yourself. "

Twisted melons are not sweet.

Seeing that Chen Yi really didn't want to go back to study, Professor Zhang didn't force it and asked another question.

"How much fuel is left for your moon landing drone today, is it enough to change orbit and slow down to fly to the moon?"

"22 percent, there is still some more when we reach the moon."

"There is so much fuel left? Can you slow down and return?" Professor Zhang's eyes lit up.

"No, the drone is not specially designed for high-temperature friction resistance, and it may crash when reentering the atmosphere."

Chen Yi shook his head firmly.

Come back, it is impossible to come back.

Only after waiting for some time, he rebuilt a rotary detonation engine, read the technical information and sent it to the professor.

If the drone is brought back now, he still doesn't know how to answer the technical details of the engine.

"It's such a pity."

Professor Zhang felt a little regretful, thought for a while and suggested: "Yifei's live broadcast today was sensational enough, don't broadcast live again during the subsequent flight to the moon.

You should know what will happen if you change your moon landing drone a little bit.

Now Yifei and your security are not in place yet.

Exposing too many technical details will frighten the other party, and it is not good for your personal safety. "

"OK."

"In this case, I will not live broadcast the follow-up moon landing, just take a few photos."

Chen Yi thought about it and agreed with Professor Zhang's suggestion.

Now his consciousness wave has 7 million, which is enough for a short period of time. If there is no live broadcast, there will be no live broadcast.

There is no need to gamble on your personal safety for the consciousness wave.

As for what would happen if the drone was changed, Chen Yi naturally knew it too.

Able to go into orbit and land on the moon.

Even after the moon landing is completed, the fuel is still redundant.

If it's a little different local product, the global express delivery will be delivered in one day, and the lunar express delivery will be delivered in three days.

Absolutely scary.
