Let Yang Ruolan accompany her parents and others to play in the capital for two days, Xu Ziling and the elders confessed, and took Li Chengcheng to the airport to return to Star City.

The straight-line distance from the capital to Star City is less than 2,000 kilometers, and at the speed of Gulfstream 550, it will take more than an hour to arrive.

After getting off the plane, Xu Ziling entered the office as soon as possible.

"Tell me what's going on."

"Aren't you idle these days, I remembered this when I was bored that day, so I've been thinking about it these days, but I didn't expect that I really found a solution to the problem, come, look at ......"

The reason why the ion engine cannot be made is because the ions are uncontrollable, and according to the current technology, it is impossible to produce the required materials at least within ten years, so that the ions become controllable.

Xu Ziling immediately took the information taken out by the lion and read it, only to understand why the lion said that he could get the engine:

With tens of thousands of various high-strength alloy materials, he finally found a substitute material, and this material, according to the current level of science and technology, can be produced, but the cost is a bit large.

There is a diamond mine and a large oil field, as well as the profitability of the group itself, the last thing Red Star lacks is capital, as long as they can make an ion engine, the cost is a bit high is something they can fully afford.

Quite excited: "That is, now as long as the gravity problem is solved, our plane can go into space?" ”

"yes, that's it." The lion is equally excited, for him, space has an extraordinary allure, once the plane can go into space, even if it can only be a short flight for the time being, this is a considerable progress, one has two, on this basis to develop hard, one day can really enter the space age, once that time, maybe he can go back to the place where he was born.

"When will the gravity problem be solved?"

Xu Ziling is very concerned about this problem, after all, even if there is an ion thruster, if the gravity problem is not solved, it is no different from the current space shuttle, it is all chicken ribs. You just don't need to use a rocket to launch it!

"Two years, absolutely no problem." The lion's answer was unequivocal.

"Okay." Xu Ziling laughed, "From now on, you can solve this problem with peace of mind, and let go of other things that can be handed over to others, and solve the gravity problem, which is a great achievement." ”

Gravity technology is not only applied to spacecraft, it is used in a wide range of applications, such as testing space equipment, creating a livable environment for future alien immigrants, and so on......

In other words, once this problem is solved, it is no longer a dream to live in space or on an alien planet.

"That's fine, but you'll have to work on the materials yourself, so I'm sure it's not a problem for you."

Xu Ziling nodded, a few months ago, he had the idea of a spaceship project, he had worked on the related problems of spacecraft materials, and he had already memorized many spaceship optimization schemes in the lion system, and he had already understood the most important issue of materials.

"Two years, no problem."

"Okay, I'll solve the gravity problem in two years, you solve the material problem, and then let's get a miniature spacecraft to try, I believe it's no problem to run to the moon."

……

The next day, Xu Ziling transferred a part of the people from the laboratory to be responsible for the ion thruster project, because there is an engine laboratory, and the ion thruster is also an engine, the relevant tests are much simpler, without too many special instruments, and there is no need to establish another site, and in just one month, the world's first ion engine in the real sense was launched.

"That's all you told me about?"

When the engine was moved out of the laboratory, Yang Kaiming, who had completed his marriage leave, came back in the dust. "This seems like an engine?"

Li Cheng has been with Xu Ziling these days, and understands the importance of the Dongdong in front of him, which is not much different from an ordinary engine, without Xu Ziling opening his mouth to explain, he said: "This is the engine, yes, but do you know what kind of engine this is?" ”

Although the words were in a questioning tone, he didn't wait for Yang Kaiming to answer, and continued: "This thing is used for the engine of the spaceship, does the spacecraft know?" This means that it won't be long before we can build ships. ”

"Ah......" Yang Kaiming's mouth opened wide.

He had no idea that the thing in front of him was actually used on a spaceship.

Even though he had seen a spaceship before, he still couldn't believe it when he knew that the engine in front of him was used in a spaceship.

I had asked Xu Ziling earlier, it was impossible to get a spaceship within twenty years, but it had only been a few months since I asked this question......

He couldn't help but be surprised.

"Didn't you say you couldn't get it in twenty years?" Surprised, he looked at Xu Ziling suspiciously.

Xu Ziling smiled and shook his head, "It's not what you think." Chengzi didn't make it clear to you, the spacecraft we are talking about at the moment is a miniature spaceship, even if the technology is mature to a certain extent, being able to land on the moon is the best result, different from the large spacecraft we talked about last time for space flight. ”

Speaking of this, he paused, "The previous prediction was also a little wrong, originally we couldn't make this kind of engine for the time being, but a few days ago, the lion found a material that could be replaced by chance, so that it could be made in advance, otherwise, this kind of small spaceship, I don't know how many years it will take to get it." ”

Hearing his words, Yang Kaiming's happy expression immediately appeared, and he slapped his palm gently, "In other words, this time it is the lion's credit?" What a look, lion. ”

The lion was busy solving the gravity problem, and came out to say hello to Yang Kaiming and disappeared.

"And when are we going to get the spaceship? I really want to go to the moon. Yang Kaiming asked again.

Xu Ziling thought for a while, "If it's a space shuttle, we can get it out in less than half a year, but for us, it really doesn't make sense to go to great lengths to make such a chicken rib, so I mean to get it a little better, these days I already have a plan, ready to make a brand new miniature spaceship, absolutely not like the current spaceship, eating a meal, going to the toilet is a trouble." ”

Yang Kaiming immediately understood the meaning of his words, and was pleasantly surprised again, "That means you can solve the gravity problem?" ”

Nodding, Xu Ziling answered him truthfully: "That's right, this technical problem will take about two to three years, and other problems such as fuselage materials will also be solved, that is, in a maximum of five years, we will be able to go to the moon." ”
