Rebirth of Northland Technology

"Well, there is nothing to do, your boys are willing to make some strange things."

Several girls have lost interest.

There is no high technology here!

On the model aircraft, after taking the traditional engine, the parts are less pitiful, the wings are completely bare.

"However, your paper is also published, don't you return to school? You have to have a holiday!"

Li Dan asked her Zhang Tianhang.

"The air engine project is completed, but there is an aerospace engine project. I have been going to go back."

---------

"That's awkward! Front way!" Feng Yan felt that Li Dan is too ink.

"The amount ..., that, this project level is high, the construction, you can only wait here. Your brand will not go to the next workshop."

Zhang Tianhang supported a half a day.

"Well, Feng Yan, let's go, I will not go in, I am here." Changzhou is very large.

"Okay, you wait for me, wait for me to visit, go back and tell you!" The girls are prosperous and ready to continue.

Nine bases, except for the road, others are good.

Eat well, drink, and are so thin.

"Shot, wait a moment." Cheng Yongxing hurriedly jumped out. "You don't joice the confidentiality system, you have the right to go in, I don't mean the information you have in the right!"

"You mean, the information inside needs to be confidential?" Li Dan asked.

"More fresh! Everything here needs to be confidential, here is the 51st area of ​​China!" Zhang Tianhang is very proud. After him coming in, I rarely send a message to my girlfriend because it is here.

"I can see it, but can't you say?"

Li Dan strokes red card hanging on the neck.

I saw it, but if she didn't let her say, it is really unimaginable for girls who like gossip. "I am afraid I can't do it!"

"You have no right! But if you look, you need to follow discipline!"

"If we can't comply with it?" Feng Yan was unfamiliar with the confidential system. "Need me to sign any agreement?"

"No need to sign the agreement, there is no consequence, but the loss trust is. Go!"

Cheng Yongxing has went to the front of it.

"Oh, you said, I feel that the pressure is bigger." Feng Yan remembered a few years ago, she and the oral promise between Yongxing.

In this group of people, only she has a discrete pressure. "Then I will not go in."

Li Dan's boyfriend is a party and does not need to hide. And she needs to be in constant construction.

"Go, more people are also good, it is rare to have a chance. You don't have to avoid me."

Changzhou is an idea of ​​understanding my girlfriend. "We do technology products, it is very important!"

"Well, I hope this time I can really see something!"

Several people continue to travel.

I have walked through two gates and came to a new area. "I haven't been here before this side!" The students have a similar feeling.

"This is after digging, now it is still excavating!"

---------

"? Wei Sher Han? How are you here?"

Feng Yan and Wei Xi Cold have a feet.

There are a lot of people in the hall, many of whom are from workers. Many people know Feng Yan, but Feng Yan does not know them.

Li Dan is more familiar with Zhang Tianhang's navigation student. Each has a lot of people who need to say greetings.

"I am also because of it. It takes a lot of superconducting and chip control, I was arrested." Wei Skin pointed to a model on the table.

"This is something, so ugly!"

Several people have finished their breath, slowly gathered next to the ugly monsters in the middle of the venue.

This is a big horn-shaped model, the thick tube wrapped in the body, reminds people's movie , very ugly.

"This is the ion engine, which is used to satellite and spacecraft!"

This time Zhang Tianhang is introduced.

Due to confidential reasons, there is no chance to show off people. Now, no matter what, everyone will speak first.

"How can I grow this? What is these lines do?"

"That is a small particle accelerator, many things are made by superconducting materials."

"Chang temperature superconducting?" Feng Yan turned a circle in the sample and did not find cooling facilities.

"The engine can only be used in space, in space, no cooling is required, the temperature required to reach the superconducting material."

Ion engine projects, is a collection of technology in recent years.

Top processes and techniques such as superconducting, semiconductor materials, IGBT, chip control, precision manufacturing are reflected in a small engine.

With the development of technology, the more advanced technology, the more it is difficult to see from the appearance. Because the technology is too fine, it is difficult to see it with the naked eye.

"The biggest advantage of this engine is dual-use:

The general ion engine is only paying attention to the weight, but the thrust is too small.

This engine has two modes, one is a simple ion spray, and the other is to accelerate ions, followed by a similar effect with chemical fuel. "

Zhang Tianhang continued to explain.

Ion engine, is a human beings under the speed of light, and the universe choice of the space is sailing.

Traditional chemical fuels, reactive expansion, to achieve thrust, but the export speed is too low, the utilization of quality is too low, and in an empty universe, it is very difficult to obtain fuel.

The ion engine has the characteristics of pushing ratio, accurate control.

In addition, its energy source can make full use of solar energy, so in the 21st century, it becomes a secondary engine preferred program for control satellite attitude.

The ion engine of nine bases is integrated into the small particle accelerator to achieve a more excellent performance. To a certain extent, it is more advanced than the ion engine commonly used by the later generations.

Ion engine, although the utilization of injection quality is high, but since the absolute amount of spray is small, the thrust of the obtained is poustic.

After integrated the particle accelerator, the positive and negative particles accelerate, and then tested after acceleration, in the middle and charge, the ion returned, also produced a large amount of thermal energy.

Ordinary gas is heated and plus the particles itself is accelerated, and it is wrapped outwardly. Thereby producing greater driving force. The principle is a bit like a jet engine.

If you can succeed, the ion engine can really do the main engine of the spacecraft.

Most gases can act as a push agent for ion engines, easy to save and acquire. No matter which satellite or comet, it can be easily obtained.

"When can this thing be practical?"

Li Dan listened for a while, it was impatient. Despite the strange shape, it brings a science of science, but the still model will take the fresh feel away.

"Fast, there will be a satellite on next year. At that time, you will see it."

The first space experimental satellite of aerospace technology will be launched in May.

This project is an aerospace technology project, but the money is the foundation fund. Anyway, I don't talk about what property rights, patents.

Now, or even the designs and manufacturing of satellite, it is in a few years, or even ten years.

This rhythm is completely unbearable for modern people who are accustomed to the month, week, and even the sky.

Therefore, aerospace technology has developed an intensive rocket launch plan, the initial period is launched every quarter, gradually transitions to one month. Continuous edge improvement, side launch.

Satellite launches will be normalized.

The current aerospace field is made of single-piece, small batch production.

Every satellite is launched, you can go to the news broadcast.

Due to the length of the cycle, the fault tolerant rate is low. Failure once, a few years of hard work. So the requirements for quality, more harder, reaction to the cost, is the high price.

99.99999 Purity gold refining cost is more than ten times higher than 99.999.

These problems have solutions in the later generations, that is, industrial mass production. There is a company, you will be prepared to launch 10,000 satellites.

Their solution is to launch low cost, low quality satellite. Which problem is thrown away.

If you build a Chang'e No.3, you have 10 billion US dollars, then 10 units?

As a result, it may be unexpected to everyone.

It is not good to build 10 units, and the price is less than 100 million US dollars!

Because of the quality control standard, it is greatly reduced!

Only one construction is built, and its success rate must be 99.999%. The construction of 10 units, the quality of each unit, can be used in 30%, you can use it!

Yongxing is also ready to take this way.

The rocket to be launched, just like a bus, keep launching. Various related experiments, where to catch up, just.

Is there any thoughts, don't guess, go directly, actually verify it, the result will come out.

Public rockets will also accept loads from several relational schools. As long as the load of nine bases is dissatisfied, they can make them a car.

However, the experimental satellite that launched it, you can't make a trial, you can throw it away, you can also use the waste.

The easiest, it is to go with a high resolution CMOS camera. After the experiment, the survived satellite continued to act as a photographic satellite. How long can you take a take?

It is estimated that the cost can be reused.

Aerospace technology, it is still negotiating with several domestic units, and can reduce the cost of launch by reducing quality requirements, and increasing the purchase quantity.

Because in accordance with the planning, the satellite emission of aerospace technology, it can reach the level of hundreds of levels in the future, and there is at least one public rocket launch every week.

The quality requirements of aerospace technology are very open, as long as half can be on the day, you can. If the price can be discussed, 13 can survive or.

The key is that it must be cheap.

Several negotiating opponents, some unacceptable for this strange requirement.

Fried rockets, satellite, smashing the brand. Therefore, negotiations are still deadlocked.

If the price is finally can't talk, the aerospace technology can only do it yourself.

"Let's go, let's go! I am hungry!"

Li Dan is impatient.
