In the eyes of the public, if you have already explored the moon, then landing on the moon should be an easy task, right?

Besides, the United States successfully landed on the moon in the 1960s. Half a century has passed, and you still haven't landed on the moon? This is obviously unreasonable!

Under such complicated circumstances, one can imagine how much pressure Fei Dun, the chief scientist of the lunar exploration project, was under! "Grandpa Fei, I think you can't rush this matter. Don't say I'm going to attack you. Although our country's current aerospace industry has made great progress and even ranked third in the world, in fact, our current technology is far from being able to reach the level of manned lunar landing!"

Others may not know about China's aerospace industry, but Lin Feng knows it very well.

With a global knowledge base, he is already well aware of the development of foreign aerospace industry.

Even the existing technical knowledge in the field of aerospace engineering in the United States can be searched from the global knowledge base.

According to his own judgment, if China wants to catch up with the United States, unless the United States stays where it is for decades, it will be almost impossible to catch up with the other party in this high-tech field!

But Lin Feng couldn't explain himself, so he could only express his views in a tactful way.

After listening to Lin Feng's words, Feiton also sighed: "Actually, I understand what you said, but I also hope to do my part for my motherland in my lifetime.

At the same time, I also have a selfish desire, which is that I hope that my name will still be remembered by future generations a hundred years later!"

Scientists of their generation all have lofty ideals and are willing to give everything they have for their motherland.

So Lin Feng had no doubt at all about what Fedon said.

Lin Feng couldn't help but ask, "Hey, Grandpa Fei, I understand your feelings, but I just don't know where our manned lunar exploration project is stuck?"

Although he had no intention of getting involved, it would be okay for him to give Fedun some advice and help.

"The most important link is the issue of carrying capacity. At present, the most powerful rocket in our country has a carrying capacity of about 20 tons when operating in the Earth-Moon orbit. In this case, the rocket can only carry people around the moon and cannot land at all.

If a forced landing is desired, the carrying capacity must be doubled to more than 40 tons.

And doubling this carrying capacity is simply a pipe dream for our current technology!"

These things themselves were not very confidential, so Feiton explained them to Lin Feng as if they were chatting about family matters.

Hearing this, Lin Feng narrowed his eyes instantly.

In the entire world, only the United States has ever sent humans to the moon, although over the years the outside world has questioned that the U.S. moon landing was simply a fake.

Those photos were also synthesized by NASA using PS technology.

However, according to relevant information fed back from the global knowledge base, the US moon landing did happen.

As for the carrier rocket "Apollo" used to land on the surface of the moon, its carrying capacity was indeed more than 40 tons, and the total carrying capacity reached as much as 45 tons.

Now, as long as he could summarize the key points of this technology and send them to Fedon, the moon landing project would be able to move forward a big step.

However, although Lin Feng can search for this thing through the global knowledge base, it is obviously impossible for Lin Feng to tell Fedon everything right now.

After all, once this kind of thing is exposed, it will trigger a series of unimaginable consequences.

It is obviously not normal that a Chinese businessman knows the most advanced technology in the aerospace field.

In addition, Lin Feng had already indirectly developed the photolithography machine technology before, so now Lin Feng dare not be too ostentatious.

However, now Lin Feng can give Fei Dun some advice so that he can have a direction to study! Then Lin Feng immediately reminded: "We can actually develop some heavy-duty launch vehicles, increase the size of the rockets, and then we can store more fuel, so that the carrying capacity can be greatly improved!"

"Haha, Lin Feng, you really only have a limited understanding of this field.

We have also considered what you have considered, although theoretically, your point of view is feasible.

But in fact, there is one most important technical difficulty in the development of heavy-duty rockets. If this technical difficulty is not solved, then the development of heavy-duty rockets will be in vain! "

Felton smiled.

However, he did not explain too many details to Lin Feng. After all, explaining such profound things to ordinary people is like playing the lute to a cow, so he was too lazy to explain anything to Qin Feng.

But Qin Feng smiled and shook his head after listening: "I know that although heavy rockets will have more fuel, when the liquid oxygen engine burns, the instability will increase exponentially because the fuel is too large.

In this case, the unpredictable increase in the combustion chamber pressure is likely to cause the entire liquid oxygen engine to explode instantly! "

After Qin Feng said this, Feiton's pupils suddenly dilated and an incredible expression appeared on his face.

At this time, Fani beside her also noticed that something was wrong.

What Lin Feng said was like a divine book to her. At first, she thought that Lin Feng was just talking casually.

But now, after seeing her grandfather's expression, she was also shocked. Could it be that what Lin Feng said was justified? After taking a deep breath, Feiton said excitedly: "Lin Feng, I always think you have a talent in the field of aerospace.

I didn’t expect you to know this knowledge point. If you are not a professional in this field, you really don’t know the truth behind it!”

"Grandpa Fei, I actually only have a partial understanding of it. I just have some superficial ideas, but I don't know if this thing will work.

Since we have come to this point today, I might as well tell you everything that is on my mind and see if it can give you some inspiration or something.

Of course, if what I say is wrong or unrealistic, please don’t laugh at me! ”

Lin Feng was already planning to reveal some secrets to Feiton, but he still had to pretend that he was just speaking casually.
