Chapter 1252

No wonder this technology leader from the aerospace field is like this.

In fact, Hall thruster belongs to the technological frontier in the world aerospace field. It uses plasma jet effect to obtain thrust. It only needs electric energy and does not need to carry additional fuel. Therefore, it is suitable to be the main power of space exploration equipment.

Of course, there are some defects in Hall thruster, which can not be overcome. The biggest one is that the thrust is too small. In this respect, the latest Hall thruster developed by the United States, which is the world's leading technology, has a maximum thrust of only 1.8n.

Yes, I'm right. It's only 1.8 Newtons. It can push an egg at most. It's pitifully small.

But such a small thrust can play a great role in the near vacuum environment of outer space. Even if the force is small, it can also push the spacecraft to make the maneuver that people want.

Because of this, Hall thruster is widely used in satellite orbit change, deep space exploration, space station and other fields.

The first generation Hall thruster was developed as early as 1974, and it was successfully applied to the test satellite.

However, after the reform and opening up, the Hall thruster project, like the shockwave wind tunnel, was included in the list of cuts and was forced to step down. It was only after Professor Yu joined the Tengfei group that the relevant technical personnel were convened again under his promotion and the project was set up within the Tengfei group, which led to the dpz-06 Hall thruster.

As for the technical level, there is still a big gap compared with the thrust of the latest American 1.8n. After all, the thrust of dpz-06 Hall thruster is only 80 μ n.

Although the thrust is small, it is enough for the third generation relay test satellite to be put into use by China Tengfei.

On the contrary, dpz-06 Hall thruster is the most advanced metal 3D printing integrated forming technology in China and even in the world.

The xenon sealing equipment for plasma generation can be manufactured at one time, which ensures that the precision of the whole propeller is higher than the current standard.

So listening to Professor Yu's introduction, those technical leaders are still very emotional.

We need to know that the main purpose of their special trip is to see if China's take-off has a backup technical solution for high-quality Aerospace Forgings. However, they did not expect to start with 3D printing equipment, j-8e multi-purpose fighter, wcnb-12 shock tunnel, Jszb-08 hypersonic warhead and now dpz-06 Hall thruster

As if they had entered the treasure house, they could hardly see a variety of things. But from another aspect, it shows that the inside information of China's take-off has already surpassed the imagination of ordinary people and reached a height that is hard to reach.

This makes the present technical leaders happy, at the same time, they can't help feeling a sense of urgency.

After all, they are not saints. In the past, old companies and factories had to take care of one or two. If these old companies and units are still overstaffed and don't want to make progress, sooner or later, they will be crushed by China's take-off companies that master core technology.

Not to mention anything else, even Northeast Airlines Group has begun to cooperate with China's take-off. Don't other units weigh their own weight?

As for the two leaders in the army and the head of the headquarters, not to mention how satisfied they are, they can be seen from their smile.

However, compared with other people, they focused more on technology and paid more attention to the practical application of specific achievements. Therefore, after a careful understanding of the basic principle and development potential of Hall thruster, the military leaders turned their eyes to Zhuang Jianye: "Xiaozhuang, what are you looking at today? How many achievements can you make before the end of the year?"

Who is Zhuang Jianye? I can't hear the implication of the leaders inside the army. This is to show some of the leaders who are able to hold hands, so that some people at home and abroad can see. The recent achievements of domestic technological development are still very impressive.

It's just

"Mainly..." Zhuang Jianye opened his mouth and wanted to say something, but after just a few words, he became eager to say nothing. The leaders of the army saw Zhuang Jianye's awkward appearance and their eyes narrowed slightly: "if you have anything, please say it. Our investigation is to solve the problem."

This is what Zhuang Jianye said. He immediately said with a rather complicated look: "in fact, it's nothing. It's just that the difference in funds on hand is too large. Several leaders have just seen that almost every project is at the forefront of technology in today's related fields, so we have invested a lot of money this year, and we are already stretched, So... "

"I don't listen to your nonsense. You can count the difference." The leader of the army is most annoyed that others are crying with him. He immediately interrupts Zhuang Jianye's talk. Seeing that the leader of the army is so straightforward, Zhuang Jianye doesn't hold back and directly reaches out five fingers: "five billion... Chief, as long as you give me five billion dollars, I promise that I will give you what you want before the end of the year. I can't do it, You take off Zhuang Jianye's head and kick it. "After listening to this, the military leaders almost didn't have a mouthful of old blood. If you think my head is worth 5 billion yuan, you can just take it. With the fragrance of your mouth, it almost sped out and brought Zhuang Jianye to the stigma of history.

NM How dare you take him as a bank? Why don't you Zhuang Jianye go to heaven?

"Two billion at most. I'll see half of the results by the end of the year. If I can't, just wait for me and see how I can deal with you!"

In the most aggressive way, the military leaders left behind their strongest words. Like Zhuang Jianye, they took the head of the headquarters to walk outside the shock tunnel laboratory.

Obviously, the big leaders in the army are angry.

However, discerning people understand that the big leaders in the army are not angry. They are just protecting the calf in another way!

50 One hundred million is outrageous. Can two hundred million be less?

You know, these technical leaders here tied together, multiplied by five, can't get two billion dollars.

What's more, the 2 billion yuan is not included in the annual budget, but is a special fund applied by the headquarters to finance, which is enough for China to take off and do many things.

Among other things, Professor Yu was stunned after listening to the leader's words. It was obvious that the 2 billion yuan was far beyond his expectation.

But can China take off with the 2 billion yuan?

"Comrade Xiaozhuang, the performance of nb-996 and nb-985 metal additive manufacturing equipment I saw earlier is very good, but there are still shortcomings of insufficient maturity. Do you think you are interested in cooperating with a mechanical Research Institute of our company to reach a new level in the manufacturing of high-performance forgings?"

Just when a group of technical leaders were thinking about how China's take-off cost 2 billion yuan, a senior researcher who had not spoken for a long time suddenly came to Zhuang Jianye and put forward an application for cooperation.

A group of technical leaders were stunned for a moment, and immediately put on a big and shameless hat to the senior researcher from the bottom of their hearts
