"Wow." Yang Kaiming screamed strangely, looking overjoyed.

The biggest impression of space life for them is that they can float around like a balloon, this phenomenon seems to be fun, but when it comes to themselves, it is not so fun.

So it's crucial to solve the problem of gravity.

Now that Xu Ziling said that he could solve this problem, how could he not be ecstatic.

There is no such thing as gravity when their special forces are trained, and even if there is such a spaceship now, it is estimated that they will not be able to adapt to it, after all, the selection of astronauts is more strict than that of their special forces, and people who have not undergone strict training really can't board a spaceship that does not solve the gravity problem.

"Is it okay to be sure of three years?"

"A miniature spaceship, three years is about the same." With the lion here, Xu Ziling's confidence is very strong, "It will be used in scientific research in the early stage, and if you want to really put it into commercial use, ten years will be good." ”

The commercial use of spaceships is certainly huge, such as ordinary space tourism projects, alien mining, and so on......

However, Xu Ziling's miniature spaceship they are talking about at the moment obviously can't do this, of course, he doesn't care about this, for him, the spaceship is a weapon to conquer space, put into commercial use, these are not what he has to consider.

Li Cheng and Yang Kaiming made a nonchalant look at the same time, "Commercial use is not something we need to consider, but the benefits in this area cannot be underestimated, and we need to say hello to Lao Nie and them as soon as possible." ”

The people of the United States had a private space trip in the first two years, Xu Ziling glanced at the news, he remembered that the report said that there were many rich people who signed up to participate at that time, although the cost of such a trip was as much as tens of millions of dollars, really according to such a market, even if it was a miniature spacecraft, his commercial value was huge.

From his point of view, he only needs to consider military use, but as an executive of a business, the commercial value cannot be ignored, and with the reminder of two people, he immediately thought that he should indeed talk to Nie Yunjie and them, so that they can make relevant plans as soon as possible.

The three of them went to the office building and told Nie Yunjie about the spaceship.

Nie Yunjie's mouth opened wide with a sluggish expression, and his look of shock was even worse than that of Yang Kaiming before.

"Oops......" patted his stiff face, "You guys are so silent that you make such a guy, it's really fatal." ”

The three of them laughed but did not say a word.

Not bothering to pay attention to the mocking smiles of the three of them, Nie Yunjie immediately asked again, "Are you sure it can be put into commercial use?" ”

Xu Ziling smiled, "Then it depends on how far you are referring to." ”

"Personal space tourism?" Nie Yunjie immediately thought of the use of a miniature spaceship.

"That's fine."

Clapping his palms, Nie Yunjie laughed, "No problem, it's OK, I'll call someone to make a plan immediately, as long as you cooperate, I promise to make a lot of money in three years." ”

In terms of the way to make money, Xu Ziling can only bow down to him compared to him, since he said so, they naturally have no doubts.

Compared with ordinary ion engines, real ion engines not only occupy an absolute advantage in terms of propulsion ratio, but also have a wider range of energy.

At present, the energy used by the ion thruster for satellites is solar energy, and the ion engine made by Xu Ziling can not only use solar energy directly, but also use aviation fuel after installing a small part.

Compared with the current aircraft engine for fighters, the ion engine is more economical in terms of fuel.

Considering the advantages of the aircraft engine with ordinary fighters in terms of propulsion ratio and economy, Xu Ziling considered replacing the engine of the FY series fighters.

"Do you think it can be done?" When this matter was proposed, Zhang Lao was quite hesitant.

In the eyes of this old expert, the fighters of the FY series are already a very mature model, is it necessary to replace the existing ones with ion engines?

Xu Ziling knew what Zhang Lao was thinking when he saw his expression, and sighed slightly, "It is undeniable that this series of fighters is very mature now, but with the popularization of foreign trade models, our self-use model does not have too many advantages, and our replacement aircraft will not come out in a short time, so it is necessary to upgrade its power and related technology." ”

A month ago, Zhang Lao knew about the existence of miniature spaceships, and from that day on, the old man took into account the military use of this kind of miniature spaceship, and even once asked whether it was necessary to develop a new generation of fighters, but Xu Ziling delayed it with an answer that he wanted to think about it.

Now listening to Xu Ziling say that the FY series fighters will be upgraded as a transitional model with the next generation of fighters, he understands that Xu Ziling is also thinking about the next generation of fighters.

After thinking about it for a while, he finally nodded: "With the emergence of miniature spaceships, the next generation of fighters has become a difficult problem to decide, so it is necessary to over-model, and it is feasible to upgrade existing models with technologies such as engine replacement." ”

With Zhang Lao's consensus, Xu Ziling quickly arranged this matter.

After years of rapid development, the technical strength of Red Star is now much better than that of some internationally famous old military enterprises, and in less than a month, the problem of compatibility between ion engines and FY series fighters has been solved.

After the prototype was tested in the wind tunnel and other issues, tests such as ground taxiing began on the second day, and then test flights and other problems began one after another.

Whether it is a prototype or a fighter off the assembly line, the test questions are already familiar to the people of Red Star, and after the first successful test flight, they have successively carried out tests such as maneuvering and extreme speed sailing.

"That's a success, right?" After a whole month of testing, the fighter named FY-1B finally passed the last test, and Lin Jianbin was excited to look at the gray fuselage that took off in the air.

A month ago, Lin Jianbin was finally transferred back to his "hometown" of the 81st Division, although the 81st Division is no longer in charge of his father, but with his own ability, he served as the captain of the famous "Thunderbolt Squadron" of the 81st Division, and his life is quite nourishing.

When old friends came back for many years, several people naturally had to get together, but during this time, whether it was Xu Ziling, Li Cheng, or Yang Kaiming, the three of them stayed at the airport, waiting for the results of the upgraded fighters, so Lin Jianbin also knew that the FY series fighters had upgraded models, so he had been dealing with fighters, and he had been mixing with Red Star these days.
