Chapter 251 This unscientific wire drawn from a device that can simulate a turbojet engine driving a generator to generate electricity, connects the current to the rectifier circuit.

The fastest update of the original thyristor rectifier circuit, to achieve this kind of efficiency is a rather complex and bulky set of equipment.

Compared with IGCT, the gap between the two is even greater than the gap between the original World War II Motorola radio station and the current smartphone.

Not only is the equipment complex and the functions are simple, but the energy consumption of the thyristor rectification itself is very large.

This is undoubtedly even worse for aircraft systems, which are already short of electricity.

President Luan of Dongda, Director Gu of the 601 Institute, Liang Hongwei, a structural engineer, Secretary Lu and Ran Ni, and Rosie personally adjusted the oscilloscope, and everyone swallowed their saliva unconsciously and stared at the screen intently.

The time that passed by the current was only a moment when it was too late to count, but it was as if everyone had been waiting for a long time.

The violent and turbulent current flows from the power supply equipment into the IGCT, as if the flood water has hit the Three Gorges Dam and fallen under the power of human technology.

The oscilloscope's screen first jumped inexplicably, but then a regular and extremely beautiful curve was displayed.

"This ......"

"Is this a success?"

Although Secretary Lu is not very good at technology, he accompanies the leader from the power system, and he is not even an oscilloscope.

The curves that fluctuate regularly on the screen are clearly the energy that can enter other electronic circuit devices after rectification.

This does not require much knowledge, even just industry common sense, to judge the results.

Principal Luan of the University of Tokyo frowned and nodded hesitantly.

"Well, it should have been a success. ”

He said with some hesitation: "It's not sure yet, you have to go through an inspection to know." ”

In recent years, the social atmosphere has been bad, which has affected the academic community.

Principal Luan has seen a lot of things about studying magic and metaphysics on weekdays, and making temporary guest appearances as scientists.

In the face of scientific research results that he can't understand, he always subconsciously blesses a certain skepticism.

And the power rectification is not a "liar"

I like the direction of the pile.

But if you can't figure it out, what if someone wants to go off the rails?

What's more, the original huge thyristor rectifier equipment suddenly shrank by almost ten times, which is too sci-fi.

Unlike Secretary Lu and Principal Luan's caution, Ran Ni and Rosie have no doubts.

After the two of them repeatedly confirmed that the images and wiring on the oscilloscope were correctly connected, although they were also in disbelief, they still cheered excitedly.

"It worked!"

"Oh my God. It really worked!"

"How did you do it......"

Rosie even rubbed her eyes and muttered to herself.

It's like asking yourself, and it's like asking Hu Wenhai.

Structural engineer Liang Hongwei and Director Gu looked at each other, both of them looking at each other with incredible eyes.

"It's not scientific!"

From Liang Hongwei's face, Director Gu was such an expression that he almost didn't shout.

This is just so unscientific!

Scientific progress should be gradual!

How can this be so that a leap forward has been made?

More than 20 people, locked up in the conference room for three days to draw drawings, a week of tape-out lithography packaging, and the things they took out could replace the thyristor rectification -- if he hadn't seen it with his own eyes, Liang Hongwei would definitely think that this person was ""

。

And it's like God saying, "Let there be light, and there was light."

The same is not strict...... And Director Gu's eyes were scorching.

No one knows better than him what IGCT means for aircraft design.

Among the various equipment of the fighter, there is no doubt that the rectifier equipment occupies a considerable weight.

The output of power generation should be rectified, the power supply should be rectified, and the electrical equipment should be rectified.

The radar should be rectified, the avionics should be rectified, and the flight control should be rectified.

It can be said that except for the propulsion power of the aircraft, which is fuel-powered, all other equipment relies on electricity.

If IGCT can replace all thyristor rectifier equipment.

The most sensitive weight for a fighter will certainly be able to be significantly reduced!

This is undoubtedly a great improvement in the performance of the aircraft.

Not only is the weight reduced, but also the reliability of the fighter is improved due to the reduced energy consumption during the rectification process, and the power supply status of the whole aircraft is improved.

For military weapons, the increase in performance is even second to reliability.

It can well be imagined.

What does IGCT technology mean to Director Gu, who has been engaged in fighter research all his life?

The real yàn equipment was connected for a long time, and it seemed that it didn't take long, and the whole real yàn room was silent.

It wasn't until Hu Wenhai coughed slightly that everyone "woke up"

Come here.

The first to speak out was Secretary Lu, who was not very sensitive to technology.

He glanced at the principal, then nodded.

said to Hu Wenhai: "Principal Luan, how to check this, you want to have a charter, right?"

"Oh, it's simple, too. ”

Principal Luan thought for a while and said, "If Director Gu confirms that there is no problem with the equipment here, he will be able to know the results after a few small tests." ”

"Of course there is no problem. ”

Director Gu and Principal Luan also have a relationship, and the character and character of both parties are guaranteed.

With Director Gu's words, Principal Luan was relieved.

"Let's get started. ”

Secretary Lu Wenhai and Hu Wenhai smiled, confidently turned sideways and let the test bench out.

"This old Gu, let's take a hand, shall we?"

"Good!"

Director Gu also knew that it was probably because Luan Zhenzhang didn't trust Hu Wenhai's side very much, so he personally rolled up his arms and sleeves and prepared to go into battle.

As Luan Zhenzhang said, the effect of the whole real yànIGCT is very clear.

What needs to be verified is the authenticity of the whole real yàn.

First, make sure that the device with the output current is working properly and that the output mode is the same as the actual yàn setting.

Then check the circuits around the IGCT to make sure that no other equipment is involved in the rectification, and finally check that the detection equipment is operating normally to ensure that the real number is real and effective.

Although IGCT was a high-tech device in the 80s, it will only be an ordinary basic power electronic device in the future, and the measurement of the rectification function will not be much more complicated.

Without going into principle, the whole inspection is very quick.

It didn't take long for Luan Zhenzhang and Director Gu to look at each other and nodded in unison.

At this point, it means.

It was confirmed that the function of IGCT was real and effective.

"I mean, I'm not dreaming, am I?"

As a scholar with a background in the power system, Luan Zhenzhang is well aware of the role of thyristors in the power system.

It can be said that without thyristors, the entire current modern power grid would not be able to survive.

In the entire human society, there are many places that need to be rectified, and it is simply impossible to count.

And the technological advancement and competitiveness of IGCT.

Apparently far more than the original thyristor.

This kind of technology is really no different from dreaming.

If it was before today.

If it weren't for Secretary Lu's personal invitation, he would definitely spit on the person who boasted of this kind of Haikou, and then treat him as a swagger and send him to the Public Security Bureau.

Smack-Director Gu slapped Luan Zhenzhang's buttocks, and the vice president of the University of Tokyo almost didn't jump up, looking ignorant: "Old Gu, why are you beating me?"

"Does it hurt?"

"Nonsense!"

"Oh, I feel like a dream, too. ”

Director Gu nodded seriously: "So try to see if it hurts." ”

"Why don't you try it yourself!"

Principal Luan's ass was crooked.

"Say so. Is this technology real?"

Secretary Lu interrupted the two "old and uncultivated"

Asked about the trend of spraying.

"This, Principal Luan, come on, after all, it's your old job. ”

"Okay, then I'll talk about it. ”

Luan Zhenzhang nodded and said, "From the preliminary examination, the IGCT technology is indeed effective. And even more than effective. It can be said that it is an epoch-making technological progress! It is not too much to surpass the existing thyristor technology only in terms of volumetric heat dissipation gate level conversion speed, and it can even be said to be completely ahead of the world's existing level. ”

"So good? Does that mean it can completely replace existing thyristor technology?"

"More than that!"

Luan Zhenzhang said sternly: "This technology can not only completely replace thyristor technology, but also many requirements that could not be achieved in the past because of the technical limitations of thyristors. With IGCT, there is also a basis for realization! I really want to say that its significance is by no means a replacement for the existing thyristor application!"

"Phew—I see. ”

Secretary Lu memorized almost every word that Principal Luan said in his mind.

"Next, I also asked Principal Luan to sort out a report, and I will take it away. ”

"No problem. ”

Principal Luan was not only not afraid to take responsibility, but was even a little eager to try.

This kind of opportunity, which is almost certain to make a name in the history of electricity, is not available to everyone.

"Mr. Hu. What about us? Are we revising the electronic system according to the standards of IGCT technology?"

Rosie and Ranni were eager to try, and after replacing the IGCT, the design difficulty of the entire power electronics system can be said to have plummeted, and many nerve-wracking problems can now be "squandered"

Technical indicators too.

"According to the standards of the IGCT, let's revise it. ”

Hu Wenhai nodded confidently.

"Who's that, Xiao Liang!"

"Almost"

Everyone was elated, but it was almost.

Director Gu's face was full of red light, and he was inexplicably excited when he thought of the prospect of IGCT technology being applied to other aircraft.

He beckoned, and Liang Hongwei, a structural engineer, beckoned over.

"You too, according to the standards of IGCT technology, recalculate the structure of the needle-eye drone. ”

"Huh?"

Unlike the revision of the power electronic system, because the weight of the front half of the drone is greatly reduced, it means that the center of gravity of the whole machine is adjusted, and the entire structure has to be redesigned.

This is really a day, Liang Hongwei thinks of the workload here, and feels like his eggs are going to break...... Chapter 252 Secretary Lu didn't have a deep understanding of technology, so after entrusting Principal Luan to ask him to make a detailed report, he withdrew first.

He is still a little idle in Shengjing, and the chief's secretary is the chief's banner, and sometimes he is quite involuntary.

Since you have arrived on the ground in Shengjing, some courtesy visits are always indispensable.

Moreover, the feasibility of IGCT technology was confirmed, which was more or less a phased achievement, and he still had to report to the above in a timely manner.

Hu Wenhai's verification only proves that the rectification function of thyristors can be realized on devices with smaller size and power consumption.

But just such a conclusion is not enough, and the report submitted to the leader behind Secretary Lu obviously cannot have only one sentence.

on a new technology.

Normally, it should be the technical holder who applies for technical appraisal.

Then the relevant departments of the state organized experts in the same industry, and everyone got together for a meeting to see if the technology had reached the claimed standard.

Such a set of procedures is often protracted and exhausting to the applicant.

And even if it is through the technical appraisal, most of the Chinese technology in these years has been shelved and become the so-called "technical reserve"

。

And the developers of the technology.

Luckily, the results of scientific research become the results of continued promotion.

If you're unlucky, maybe even a month's bonus will be gone.

"What an IGCT for this. Shall we take it to the real yàn room of our Tokyo University?"

Principal Luan smiled, thought for a while and said, "Regarding power engineering, we also have a real room in Dongda, and the equipment and technical level are quite good. The measurement and verification of specific numbers can be carried out quickly. ”

He now wants to understand the principles of IGCT with all his heart, and he must be excited to have the opportunity to study it directly up close.

However, when Luan Zhenzhang reached for the IGCT circuit board, he didn't want his hand to be held down by Hu Wenhai.

"This IGCT circuit board can't leave the 601 Institute. ”

Hu Wenhai said very firmly: "At least I want to ask." Principal Luan, what is the level of secrecy in your Dongda Shi yàn room, and are the staff reliable?"

"What does Comrade Hu mean by this?"

President Luan was stunned, the real yàn room of Dongda Electric Power Engineering is a provincial-level real yàn room, which is very good in the province.

But at the national level, it is the role of the second echelon.

Of course, there is no high level of secrecy in such a real room, and the staff obviously will not have a special political trial, and the background is completely clean.

This is different from 601.

As the highest institute for the design of China's fighter jets, the 601 Institute is a dog with "roots and seedlings"

"Red and specialized"

The level of confidentiality of personnel is very high, and the confidentiality system is also perfect.

601 is definitely stronger than 611 at least in this regard, and apart from the leak of the edict, there has never been a wall climbing party in the vicinity of Shengjing 601.

As for the 611 wall climbers.

Thirty years later, it will soon become a local industry.

A technical secret placed in the 601 Institute can still be called a secret.

But when you put it in the open room of a public university, the Eight Achievements can only be turned into honey technology - specially designed to attract bees and butterflies.

Hu Wenhai didn't dare to gamble, betting that the real room of Dongda would not leak the news of this technology, or even simply provoke commercial spies.

Is IGCT technology powerful?

Terrible.

Is it good to use?

Good.

But this does not mean how difficult it is to produce, but purely a matter of thinking.

This thing can be made with the technology of China in the 80s, as for the United States, the Soviet Union, Japan, Germany, France, Britain, Italy, and the Netherlands...... A country with higher chip manufacturing technology than China in this era.

It can be said that it is like a carp crossing the river.

Without getting the real thing, scientists in these countries may be able to open up this idea even if they listen to two principles.

Therefore, unlike lithium battery technology, IGCT technology must be tightly hidden before it is ready.

It is precisely for this reason that Hu Wenhai will never agree to take the IGCT circuit board to the Dongda Shiyàn room for testing.

"I mean, if Principal Luan wants to conduct an in-depth test of IGCT technology, he can only do it in 601 schools. It's not that I don't believe in Todai, but IGCT technology is very important and we can't face the risk of leaks. ”

Hu Wenhai said so, Director Luan Zhenzhang, who nodded silently.

Standing in the position of Director Gu, out of the tradition of the Chinese industry, there is an impulse to keep any information confidential.

After the use of IGCT technology, whether the combat effectiveness of the fighter can be further improved and to what level is very necessary for secrecy.

Of course, just like the use of IGCT technology in needle-eye drones, major structural surgery is required.

If the J-8 or J-8 II wants to go to IGCT, it requires more preparation.

"Does the 601 have all the equipment that can be tested?"

Luan Zhenzhang turned his head to Director Gu and asked.

"Well, we're not a professional power electronics room. ”

Director Gu spread his hands, there was no electronic and electrical equipment in the aircraft design institute, and this could not be blamed on him.

Even with such equipment, Director Gu didn't dare to come out of the way.

Obviously, the water inside is deep, and our research institute of the Ministry of Aviation Industry cannot afford to wade into the troubled waters of the Ministry of Electric Power Industry.

If there is a problem behind the test results, it will not be possible to be bitten by someone from the Ministry of Electric Power Industry...... "What should I do?" ”

Luan Zhenzhang scratched his ears and cheeks anxiously.

It's like Peach's Monkey King.

His eyes suddenly lit up, and he said, "Why don't I borrow the site of 601, the equipment can be moved from the University of Tokyo, and I can also arrange reliable manpower for the researchers." ”

Northeastern University was one of the best schools in Northeast China in the 80s, and it was no problem to find a few reliable researchers.

"Isn't that too much trouble?"

Director Gu was a little moved, and took it upon himself to take out the 601 and put it on his own turf for testing.

601 will also be the fastest to know the result.

"It's not a big problem. ”

Luan Zhenzhang is a little confident: "The test is not complicated from the project, as long as there is a certain amount of basic equipment, it is enough." ”

"That's good. ”

Director Gu nodded: "I'll go and arrange the venue." As soon as the equipment and personnel are there, you can start testing immediately. ”

Director Gu himself is also hot, hoping that IGCT technology can really pass the guò test.

"Comrade Xiaohu, this is always okay, right?"

Luan Zhenzhang didn't forget who had the final say here, and turned his head to confirm Hu Wenhai's attitude.

Hu Wenhai, Luan Zhenzhang and Director Gu had eager expressions, so they had to smile wryly and nodded.

This time, Luan Zhenzhang reached for the circuit board of IGCT, and Hu Wenhai finally stopped stopping him.

I saw Luan Zhenzhang as if holding the emperor's crown, carefully removing the IGCT circuit board from the real stage, and then carefully examining its appearance.

"If it can really replace thyristor rectifier circuits......"

Luan Zhenzhang estimated a little in his heart.

The demand for the power sector alone can be said to be never-ending.

As for the other possible directions of its application, he was too confused to think about it at all.

Even if it is the crown of Emperor Laozi, counting the GDP of the feudal empire of any ancient dynasty, I am afraid that it really cannot be compared with the meaning represented by this circuit board.

The interests represented behind this circuit board are truly rich and rival countries.

For example, the Americans have long had plans to use all-electric propulsion warships and tanks.

However, no actual product was ever produced.

Why?

It can't be solved in power semiconductor technology.

The switching frequency of the thyristor is too low!

The switching frequency is low, the filter circuit is larger, and the thyristor-related circuit is more complex.

IGCT solves the problem with one tube, and the thyristor needs two or three times as many units to solve.

And even if the thyristor struggles with the overlord to get on the bow, the all-electric efficiency makes people cover their faces.

The efficiency of the all-electric drive is on par with that of traditional mechanical-hydraulic transmission.

With IGCT, the all-electric transmission efficiency can be increased by 20% compared to the traditional mechanical hydraulic transmission!

If the Americans know that there is such a thing as IGCT - pro.

Do you still remember the last Iraq that was fooled and lame by Mr. Hu?

"Alright, let's hurry up and get to work. ”

Luan Zhenzhang said excitedly to Director Gu: "I won't go back to Dongda, find me a phone, I'll call and arrange for someone to send the real equipment over." ”

"That's good, you use my office phone!"

Director Gu stared at the circuit board in Luan Zhenzhang's hand, as if he was afraid that he would walk unsteadily.

Always ready to rescue.

"Director Gu, Principal Luan, in order to avoid suspicion, I won't participate in the next test. ”

Hu Wenhai coughed, and the director said: "If there is no problem, I plan to continue the needle-eye drone project." ”

"Oh, of course no problem. ”

Director Gu and Luan Zhenzhang touched their heads, and while studying the IGCT circuit board, they said: "Comrade Xiaohu has any other requirements, you can just tell me." It's just that we took this circuit board, and it won't affect the development of drones, right?"

Hu Wenhai waved his hand absently, and then lifted the cardboard box on the ground to the test bench.

Brush - his hand pulled outward, and a stack of packaged IGCT boards was pulled out.

He patted the thick stack of IGCT circuit boards, and showed eight snow-white teeth with a standard smile: "Director Gu, don't worry, I have enough IGCT circuit boards here." ”

Of course, Director Gu had heard of Hu Wenhai's deeds, and he read them as "business transactions"

Writing "Extortion"

Of course, I know what I can do.

Otherwise, the poor and crazy 601 would not have been able to leave the Ministry of Aviation Engineering and turn his head to Hu Wenhai as a thigh pendant.

casually thought about how much benefit these IGCT boards could be exchanged for in his hands if they could be sold to the Americans.

Even if Director Gu is quite "pure"

, and in this regard "barren"

The imagination also knows that this is bound to be a very large number.

Wen Hai casually patted the few times on the box, Director Gu and Luan Zhenzhang felt their hearts skip up...... (To be continued.)

PS: Let me tell you a bad joke: 66 years after the founding of the People's Republic of China, the Army of the Chinese People's Liberation Army was finally formed!

-- In fact, the leading body of the army was established, and our navy and air force are finally no longer the army navy and the army air force!
