"For example, in the current world's top engines, a lot of high-precision blade-sized turbine blades are used inside, and there are many precision holes on these blades. How should the holes be arranged? How does the air path go? How to tighten those screws, how much is the balance budget distance to flow out after screwing, etc., these are all skills that only an excellent assembler can master, and in this regard, our talents are indeed very lacking. ”

Professor Wang continued to fool Jin Xiaoqiang and said, but what he said was only part of the truth, and Jin Xiaoqiang also roughly stabilized his mind at this time, and soon he found the loopholes in what Professor Wang said.

"Gotcha! Professor Wang, don't fool me, there are so many talents in our Celestial Empire, if you want to say excellent manual assemblers, most of them are monopolized by our military, don't fool me in this regard, because in our company, in the assembly line, the current best assembly master is still eliminated from our domestic military assemblers? ”

Jin Xiaoqiang said with a smile, it is true that there are many excellent technicians in their company, many of them are from the original military enterprises, some are brushed down because they are old and do not meet the strict requirements of the military, and some are brushed down completely because the technology does not meet the requirements of the military, but once these people go to the place, they are all treasures.

Although their level is not eye-catching to learn from the military, for civilian industrial entities, their assembly skills are still very good.

When Professor Wang saw this Jin Xiaoqiang, he actually woke up from his daze so quickly, and he also pointed to the core of the problem, and couldn't help but glance at Qian Longjiang, and then could only shake his head and smile.

And Qian Longjiang hurriedly said to Jin Xiaoqiang.

"You kid, it's really a monkey spirit, a monkey spirit. It's no wonder that he was able to make such a big splash of business at such a young age. ”

Qian Longjiang was obviously changing the topic and resolving the embarrassment, but Jin Xiaoqiang didn't eat him, he said directly to Qian Longjiang.

"Gotcha. Old Qian, we are also old acquaintances, don't fool me anymore, just tell me directly, call Professor Wang, Professor Li, and me together today. What the hell does that mean, right? ”

Hearing Jin Xiaoqiang's question, Qian Longjiang's expression also became serious, and then he sighed and said to Jin Xiaoqiang.

"Forget it, I don't think I can fool you, but there are some words that I don't understand, I think it's better for Elder Wang to explain it to you."

Jin Xiaoqiang turned his gaze to Wang Lao again. Wang Lao didn't flicker anymore at this time, he picked up the small wine cup in front of him and took a sip gently. Then he narrowed his eyes, as if he was savoring the softness and longevity of the wine, and after a while, he opened his eyes, and at this time, his whole person's expression changed, as if he suddenly became energetic, not at all like an old man in his seventies and eighties, and began to explain to Jin Xiaoqiang.

"Okay, Kim, then I'll start telling you the truth. You are also engaged in industry, and you are also engaged in physical industry, I think you should have heard of the term 'industrial crown', right? ”

Wang Lao asked Jin Xiaoqiang first, of course Jin Xiaoqiang knew what the so-called 'industrial crown' was, and he nodded.

In the industrial sphere of the world at the moment. There are only two that can be called the 'crown of industry', one is the aero engine of jet aircraft, and the other is the microelectronic chip in the field of electronics.

"Well, I'll tell you about the aero engines of jet planes that we've been working on. In a real industrial empire, the aero engine can be called the scepter of the king in this empire, and only if you master this technology, you can be called a real industrial power, but we just don't have such production capacity. ”…,

Professor Wang said this with a long sigh, and Professor Li Gang also had a sad and angry expression, obviously for so many years, the two of them have not been able to make much progress in the field of aero engines, which makes both of them feel a little disappointed and frustrated.

"Aren't we already building engines for the Russian AL31FN model?"

Jin Xiaoqiang was also half a military fan in his previous life, so he still has some understanding of the country's actions in the field of aero engines, and at present, although my country has not officially announced it to the public, many people know that we are preventing Russia's AL31FN engine, which has been boasted for a long time in later generations, but it has not been able to be mass-produced.

Later, on the J10, it still had to rely on a large number of imports of such engines from Russia.

When Professor Wang heard Jin Xiaoqiang say this, he raised his head and looked at him with very strange eyes, and then turned his head and said as if talking to himself.

"It's true that the engine of Russia is built, but is it true that the technology of the Russians is so easy to make it? Besides, the Russians themselves are not bad intentions, and the engine they sold to us is itself a reduced version, but unfortunately there are still some people messing around with it somewhere, aren't they afraid that it will be a waste after it is made? ”

The old man seems to be very angry, obviously not very interested in Russian technology and the AL31FN engine, but it is true that what he said is also the truth.

In his last life, Jin Xiaoqiang has also seen reports about this engine on TV many times, but it is generally on the National Day or the Spring Festival, and then it is X's birthday, scoop it out for the people of the country and X as a gift, as for the real practicality, hehe, you can only use three words you know to replace it.

If nothing else, just for the sake of that, a series of imports of such aero engines from Russia will know.

"Humph! Wouldn't it be good to spend all this money on the research and development of our basic materials and the establishment of some actual laboratories? ”

Old man Wang seemed to be very angry when he mentioned the Russian engine, and Jin Xiaoqiang didn't know why, but Qian Longjiang coughed twice, and Li Gang also dragged the teacher's clothes under the table, signaling him to go off topic.

"Well, I'm a little off topic."

Professor Wang woke up from the anger he had just had, and at this time he also realized the truth that family ugliness should not be publicized, and hurriedly apologized to Jin Xiaoqiang.

But don't look at Jin Xiaoqiang's young age. But he knew very well that what Professor Wang said was right, it seems that such a situation of laymen leading insiders is really very serious in China, and it is not only prevalent in state-owned enterprises. This is true even within the military-industrial complex, and it is really worrying that it has been going on for a long time.

"Okay, I'll talk about the current situation of the development of aero engines in our country. Our current engine research and development situation is mainly to imitate Russian aero engines, and the AL31FN you mentioned is the main object of our current modeling. But there is a big gap between our aero engines and Russian ones. The first step is in terms of design, there is a gap between our experience and others. The second is in processing and manufacturing. The third is experimentation. In terms of design and processing, let's not talk about it for the time being, let's just say that this experimental aspect, for example, if you make this blade, you have to go to a special test bench to test its total life and unit time life. And our testing ability is not as good as others, so you don't have a count in your heart. If I know the characteristics of each part, then I know the total characteristics of each part together, and I know what its total life is. What is the thrust-to-weight ratio and so on. But what if you can't test your ability? It can only be assembled into a complete engine and burned on the test bench, so that the development cycle and cost will become larger. The conclusion can only be concluded when several engines are burned out. If I have a compressor, a turbine shaft, a combustion chamber, a blade, a nozzle, an afterburner, etc., then the designer has a count of the performance and life of each part, and the whole machine is naturally clear. Otherwise, I would only be able to make a few whole engines and burn one. One power shock, one bad weather, one damp corrosion, thousands of hours of burning, thousands of tons of oil drinking, all added to the cost. And the previous kind of sub-project test. There is no need to run the whole machine. For example, if this is a temperature problem, I will heat you, and the heating does not necessarily require burning oil, it can be electric heating, if it is a fatigue problem, I will do the fatigue test of this component alone. So the engine can't catch up with the design of others, and that's a reason. This is just the gap between us in experiments, just because we don't have a special laboratory, test bench, management chaos, and no detailed test plan, which often causes a very big waste .........,

The old man became more and more angry the more he talked, and in the end, he began to turn to certain aspects, which made Qian Longjiang look very embarrassed, and had to cough frequently to remind the old man in front of him.

And Jin Xiaoqiang can be regarded as seeing it at this time, it turns out that this old man is an old and angry young man, and he is also a straight person, he must say anything dissatisfied when he sees it, no wonder he is so old and so powerful, but now his military rank is not as high as Qian Longjiang.

It seems that it must be the usual way of doing things, which has offended many people, in a society like the Celestial Empire, where nepotism is not meritocracy, such people can be popular, then there are ghosts.

Qian Longjiang was almost hoarse, so this Professor Wang turned around, so he changed to an apologetic smile and said to Jin Xiaoqiang.

"Hehe, I'm sorry, I'm off topic again, off topic, Xiaojin, don't mind."

"No, of course I don't mind, of course we have to be wary of such improper behavior."

Jin Xiaoqiang likes this straight old man a little bit at this time, if you are engaged in scientific research, you must have such a stinky and hard spirit that is not afraid of power, otherwise you will only be able to slap the horse, you can only do a face project, what else can you do scientific research?

"Alright, I'll move on. Our country's aviation power unit is now dedicated to the study of Russian aero engines, but in my opinion this is not advisable, with such money, it is better to vigorously invest in the research of our basic projects, vigorously lay a good foundation for our research and development personnel, especially in the field of materials science. Of course, there is a certain reason why we are vigorously suppressing Russian aero engines, after all, the international political situation is there, the external situation we are facing is very severe, and Western countries are trying their best to blockade our research in the field of aero engines, so we are also

I have to embark on the road of dominating Russian aero engines, but in the long run, I am not optimistic about this road, after all, Russian aero engines are not king. ”

The old man is an old expert who has been immersed in this field for many years, so what he said must have a certain truth, but the truths he said are very fresh to Jin Xiaoqiang, a semi-military novice.

In the past, he always thought that Russia's fast engine was very advanced, after all, it was a military power that often argued with the Yankees, but now in the eyes of Wang Lao, their aero engines are not in the stream, which makes Jin Xiaoqiang feel very strange.

"Oh? Why, Wang Lao? ”

Jin Xiaoqiang asked, Wang Lao glanced at him, and then explained to Jin Xiaoqiang very arrogantly.

"This has to be explained from the purpose of the operation, the Russian Air Force's combat emphasis is on the first five minutes of the fight, these five minutes I am stronger than you, I am the winner. Of course, my five minutes are guaranteed by 2,000 people and 10,000 hours, and your five minutes are guaranteed by 3 people for one hour, and the cost is different. When you don't have scientific management methods, what you pursue is not cost-effective, but winning. The Russian side also knows that it lacks finishing capabilities, so the performance of the aero engines they process cannot be compared with those of Europe and the United States, so that their air force is very different from the air forces of Europe and the United States in terms of operational theory and thinking, and their strategic thinking is that you fight your high technology, and I fight my high investment. Aero engines in Europe and the United States rely on precision to produce high thrust-to-weight ratios, while Russian engines rely on thermal energy and cooling technology to adjust the gas temperature to the highest level without burning the engine. If the current aero engine wants to improve the thrust-to-weight ratio, there are only a few ways, one is to increase the temperature and increase the thrust, and the other is to reduce friction and loss. The Russian aero engine relies on being able to withstand extremely high temperatures, so that it can compete with the aero engines of Europe and the United States with developed precision manufacturing in a short time. ”

Wang Lao explained to Jin Xiaoqiang the general difference between Russian aero engines and European and American aero engines, and Jin Xiaoqiang suddenly realized after listening to it!
