Rule system

Huanan City scientific research base?

Expert group?

Zhao Yi also felt very interesting. In the past, Zhao Yi can only look at the domestic-air-mother, the understanding of its technology is only through the media report, can go directly - the mother's logistics research base, it is quite good. University practice.

"University practice class!"

"This word is really very delicate ..."

Zhao Yi thought about smiling.

There is no special study in recent hours, and the problem of particle mathematics can slowly think, to participate in a 'university practice' is also good.

One week later.

There is a call to say hello, there is a driver in military uniform, and Zhao Yulian is connected to him, he is dedicated to bring Zhao Wei to the research base.

People wearing military uniforms are just waiting outside the school. Zhao Wei went back to pack your bags and went to the student dormitory to take a computer.

Li Renxi saw Zhao Yi's computer, weird asked, "What's wrong, going?"

"Yep."

"What do you do? Lead award? Or participate in academic conference, or what else, I guess ... Do you want to do a speech?"

"No."

Zhao Wei said very little, "I am going to participate in college practice, don't you go?"

"What do you practice, why?" Li Ren said asked, but also a small sound, "I have never heard of practice lesson?"

Zhao Wei shook his head, "I don't know, notify me anyway." He said with the computer.

Li Renxi sent the door and immediately visited the class, and entered the school's internal network check 'practice'.

Meng Yanyou came in.

Li Renxi asked, "You also have to pack things, go to practice lesson?"

"What practice lesson?"

"Practice lesson? Zhao Wei went! I thought it was good to go." He means a top student.

Meng Wei shook his head, "There is still lesson in the afternoon, what practice lessons, you must be fooled."

"..."

Li Ren said that he had a mouth for a long time, and he suddenly angered. "Is Zhao Wei, it's not a gather!"

"I am so fooled!"

Meng Yu looked at the past with a strange eyes next to him, and he nodded directly to this sentence.

......

All the way, eight hours.

Zhao Wei took the army - the car arrived in the scientific research base of Huan'an City, and it feels that the whole person is somewhat embarrassing, and the car has taken a piece of road.

There is a special person to put the dormitory, then he went to the canteen to eat meals.

This is already evening.

Zhao Wei is the earliest, there is no other person in the time being, and there is no such guest in the evening. He saw the researchers in several bases, greeted a few words almost going to sleep.

I woke up after eating breakfast next day, the scientific research base became lively. This time he did not find the R & D center. Someone in the door is there. "Zhao's unparalleled, famous!"

"It's really young!"

There is a middle-aged man wearing a white military uniform, and the passionate is handshake, but also self-introduction. "I am Ma Mingwei, I am in a timely man, Zhao's academician, told me a horse?"

"Wei ... Master, call my name." Zhao Wei said a little bit awkward, and I also laughed naturally.

Ma Mingwei is about 50, called a 'brother' is really called young, but it is noble to talk about the title, the suffix is ​​the 'Wei' word directly called 'Viagra', it is not very nice.

The two people are not talking about the topic.

Ma Mingwei is especially waiting for Zhao Wei. He welcomed Zhao Wei to the building, and he also talked about things directly. "This time, I will say it above, I hope there is you in the expert group, I am seeking you!" "

Zhao Wei asked, "Is there any problem?" He said that he explained in advance, "I am engaged in theory, technology, application problems, I don't understand."

"But don't say so, you are recognized master, computer experts! And, I know, you give the domestic satellite navigation system, design mathematics, right?"

"That's it."

Zhao Wei nodded.

Ma Mingwei, "This time, we are also almost the situation. My team is to do powerful engineering, responsible is to - mother, the contents of the ejector."

"Electromagnetic ejube?"

"Yes, you know!"

Zhao Wei asked with interest, "How is it progress now? Can you install it to Air - Mother?"

Ma Mingwei shook his head. Now this is certainly no hope, maybe it can be. We now mature technology, only steam power ejection. Electromagnetic power has a lot of problems to overcome! "

He said that it introduces electromagnetic ejection technology.

Airborne Directors are used for the takeoff of the carrier, and the usage said that the straight white is the same as the spring, and the carrier machine is directly flying to the air, and the processes are directly completed.

When a plane is bounced, it doesn't have to go to the runway, and the speed of take-off is definitely greatly accelerated.

The technique of steam ejection is relatively low, and the practicality is not very strong, and the electromagnetic ejection is in the international perspective technology. It is the most cutting-edge technology. It is only the Ford-Mother, the mother, is preparing to load the electromagnetic ejector. Electromagnetic ejection has many advantages compared to the steam type, such as small volume, low efficiency, high efficiency, light weight, operation and maintenance cost, and so on.

Electromagnetic ejection technology is considered to be one of the core technologies of the future flight-empty mother-ship.

The electromagnetic ejector is consisting of four most components, which are power supplies, energy storage devices, ejection motors, and overall control systems.

The power supply is naturally not to explain more.

The energy storage device is also called the 'forced energy storage device', just like a lithium battery in which the car must be stored, the electronic device achieves normal operation when the car does not start.

The ejection motor is the core part, like the car's engine, is responsible for driving the core of the carrier machine.

"We hope you to look at the control system." Ma Mingwei explained that "the control system is the central nervous, which is the brain of the entire Emals system. To accept all sensors, to issue control instructions according to different situations, but also to coordinate The operation of the entire system, and so on. "

"The control system is the core and puts the whole components together."

"But this, telling the truth, our team's confidence is not enough, I am afraid to get a control system, and the results often have problems."

Ma Mingwei frowned explained.

Zhao Wei is.

No matter what kind of equipment, equipment, parts do, soft cores must also keep up, otherwise the hard facilities are high, and they do not have effects. The soft core can make the equipment and equipment efficient.

This is the same as the computer operating system.

Configure a high-end computer, install a Win2002 operating system, and it does not have an effect, equal to wasteing hardware configuration, but the soft core is not the higher, the better is the best.

Ma Mingwei and Zhao Wei talked about it, and took him to the operation room and found a big overlay design drawing.

Various design densely numb, it is dazzling, because it hopes that Zhao Wei helps to look at the control system, and put forward some improvement opinions, Ma Mingwei's explanation is very meticulous, starting from the power system, constantly explaining, mainly Let Zhao Wei understand the overall architecture, know what the control system does.

The control system is not only controlled hardware, but also needs to adjust and issue instructions according to the situation.

For example, aircraft type, environmental climate, aerial running state, etc., according to the known parameters, the control command is issued, but also adjust the synergy of power generation, energy storage, and power electronic division, so that the system works high speed. High precision and high reliability.

The loading time of the force is critical.

The loading method of different aircraft is also different, and it is necessary to make changes to it.

The control system must be self-regulated, and the self shall issue an instruction according to the sensor's data, while also minimizing the impact on the power electronic system, power supply, and energy storage system.

and many more.

Management, communication also has many problems.

During the constant explanation of Ma Mingwei, Zhao Wei also said that he did not understand the place.

"Why is the determinated power solution is an exchange of electricity? Just now, is the DC power supply? If you are saying, DC is not better? The problem will simplify."

Ma Mingwei shook his head. "The original design is AC power, the technology there is also an exchange of electric. The DC program has also thought about it. It is designed. You see the drawing, the power can't keep up. When the power is working, the load The impact is very large, the power supply capacity needs very high, and the AC power can meet the needs. "

Zhao Wei listened to some nodded, "But I think it can also try the DC's program." He said that he had taken the drawings just now, pointed to a few positions. "I think these places can be corrected."

"How to fix?"

Zhao Wei said very seriously. "For example, here is a normal power supply. But can use a brushless stream engine. If the output voltage can be lowered, the demand for power supply can be reduced."

"Also, here, you can increase the number of seaflors, and do more thin, you can output higher power ..."

"Also, here. Put the rotating motor stator longer, the power output is indeed more stable, but I think it can consider doing two options together, let the rotary motor rotor and rotate the motor rotor, the length is constantly switching, You can change the power mode to adjust ... "

"Also, here ..."

Zhao Wei said six points, then stopped and drinking the water, and immediately twisted the head to see Ma Mingwei, added a sentence, "I don't quite understand the skills," said that I said that I said it is not good. Don't be embarrassed. "

Ma Mingwei did not answer, he was completely stunned, and he went back to God for a long time. It quickly found the paper and pen, recorded that Zhao Wei said, then pulled a chair to sit down and started draft Write a picture.

This is more than half an hour.

Zhao Wei did not disturb Ma Mingwei, but turned around in operation, then simply went to the corridor, seeing the scenery in the glass, the people who just entered the operation saw Zhao Wei, I was interested, "Zhao" Academician, how to stand here? Horses? "

"Inside, but don't bother him."

"Oh."

Later, several people were standing at the door, looking at Ma Mingwei to write paintings in the inside, discussing each other, what he is doing.

at last.

Ma Mingwei smashed a sigh of relief with a surprise, shouting Zhao Wei, "Zhao Academician! Zhao Laun! What about people?"

"Here."

Zhao Wei went in, others also followed.

Ma Mingwei took a deep breath and opened a mouth.

"It is feasible, it is really feasible!"

He said to other people, "from today, we have to increase a DC program in the part of the power supply."

Others are also very convinced, "Why? Mathers, DC plans are not given up?"

"It is also exchanged there in the M country."

"Not DC power is not enough."

Ma Mingwei pointed to the drawings just now, "said a few opinions," I was also surprised, but the opinions were really good. After the revision, the DC plan can fully meet the demand. "

He said that surprised Zhao Wei, "Zhao Academician, Zhao, I really didn't expect, you still understand the problem!"

"Oh, I don't know much, I think of it, say a few words." Zhao Wei quickly said.

"Modest, too humility!" Ma Wumeomao said, "If you just understand, we really don't understand anything. You have a few ideas. If you can make a DC plan, a lot of AC power The problem encountered can be avoided. "

"So, we continue ..."

Ma Weiming took the praise to Zhao Wei continued to introduce.

Others are also surrounded.

The next is to force the energy storage device, the energy storage device can alleviate the pressure of the generator, and absorb the energy of the generator when the ejector is not working, so that the generator is almost unaffected by the impact load.

Forcing the principles of the energy storage device are not complicated, but it is very troublesome, it needs to be solved, that is, when the electromagnetic dasse is running, when the plane takes off, it will produce powerful braking force to prevent the generator from continuing to operate, the motor will be unable to operate. Drag, you must have a powerful energy storage device that is free to rotate, forcibly dragging the DC generator to run, thereby completing the impact load process.

The design of this process is not as simple as a storage lithium battery, and it is necessary to consider the side, and the energy storage device will also be a complex machinery.

Zhao Wei carefully listened to Ma Mingwei's explanation, and didn't know that they didn't understand, they were constantly nod, because the principle of forced energy storage devices was relatively simple, Ma Mingwei introduced some intended to skip.

At this time, Zhao Wei suddenly opened the mouth. "I think you are still in the design, still some shortcomings!"

"what?"

Ma Mingwei asked with doubts, "Zhao's brother, then you said."

Others also feel puzzled.

Everyone is the impression of Zhao Wei is 'mathematician', 'computer expert', and the AIDS research in the previous period of time is boiling, and then the 'medical research expert' is not over.

but……

power supply? Energy storage? dynamics? Electrical engineering?

These can be application technology, and mathematics, computer theory, and medical research is complete!

Zhao Wei seriously thought about it, or said, "I felt that your design was still in a position in the mandatory drag engine." He pointed out a position on the drawing, "Just here, let the energy storage device Work, it is a waste, just like a mobile phone charging, it is full of electricity, it is not needed to join. "

"Also, here, the core, the impact of the plane takes off, this is a technical difficulty, but you have not considered this program, which is to increase a storage power supply group, which is two groups, there is a group of special dealive shocks. When running, this can increase the power, and it is also used in alternative replacement, or the pressure of the output power of the energy storage device can also be reduced. "

"Also, here, why don't you compress it? If you don't have to be, you can compress it, you can reduce the occupied space. If you say it, use two groups of energy storage devices, you can design This look ... "

"and also……"
