"What? Three million dollars! ”

Brown looked like he had seen a ghost, and originally thought that this news was only a few million dollars, but the offer Brown heard was more than ten times his own psychological expectation, which was simply a lion's big mouth in the lion's mouth.

As if he was angry, Brown laughed instead, and that expression was really not enough to describe in words, and no matter how he described it, he would never be able to describe it.

Fortunately, Yang Hui didn't really want this money, compared to the 30 million US dollars, Yang Hui wanted to get some technology that Southwest Science and Industry urgently needed.

The high price of $30 million is just an appetizer first, and this Mr. Brown, who stimulates GM to negotiate, is a later request to explore the way first.

Sitting on the side without saying a word, watching Brown make all kinds of funny expressions, judging from the current richness of expressions, Brown's expressions in these few minutes can definitely make a big seller, and of course, it can also be a funny dynamic picture.

After performing this wonderful meme transformation technique, Brown found that no one cared about him, as if he was flattering the blind man. After a long time, he quieted down and asked aloud.

"Well, let me stress once again that our company is here to save valuable time to buy this design flaw from you, but this does not mean that our General Motors must be eaten to death by you, and your arms sales to Thailand also need F404 engines, and everyone hopes that the engines provided to Thailand in a few months will be free of design flaws."

There is a faint hint of threat in these words, and I have to say that an old company like GM is indeed powerful enough, and Southwest Science and Industry can indeed not stiffen the relationship with GM now. The two sides need to continue to cooperate in the future.

"Alright! In the spirit of friendly cooperation between our two sides in the future, I also think that we should not talk about money. At this time, it really hurts to talk about money, and we need a safe engine for Thailand's military procurement project. ”

Seeing that Yang Hui changed his words. actually said that he didn't want money, isn't the change before and after a little too big, Brown can't react a little, these Chinese people are really old-fashioned!

If you don't take advantage of it, you are a bastard, Brown seized the opportunity and immediately climbed up the pole, which is also quite fast.

"Yes, yes, talk about money and have more feelings! The friendship between China and the United States has a long history and will last forever. We also have a deep background of cooperation, so are you willing to provide us with this news free of charge? ”

Yang Hui looked unhappy with this kind of cheap expression, fortunately Yang Hui did not have the idea of providing this design flaw for free, just kidding, how can there be a free lunch in this world, the reason why I don't want money is because there are things more important than money.

"No, no, Brown, I'm afraid you're wrong, we do don't need money. But we want other things, like some technical information, which is what we are more interested in. As for the design flaws of the F404 engine, we even have a very good overall solution. At that time, GM can directly use this solution to improve production. ”

said 1,000 to 10,000, only to find out that this ghost Southwest Science and Industry was playing various technical ideas accumulated by General Motors, which made Brown a little impressed. In this country where there is a shortage of dollars everywhere, this company does not want to give up dollars. On the contrary, it is not normal to ask for technology.

For Southwest Science and Industry not to want money and technology, Brown has some ideas of his own. If it is just a simple technology, as long as it is not too sensitive, everything is easier to solve, and in the eyes of giants like GM, a single technology transfer is not unacceptable.

"Do you want technical information? You have to think about it, and asking for technical information means that you can't get any more dollars, and this is an international hard currency, and I think you definitely need these green dollars even more. ”

Brown looked like a good old man and persuaded that in his eyes, this poor country now needs more dollars, dollars, and more dollars, so he keeps reiterating this, hoping to help Southwest Science and Industry.

"We thought about it, we don't need money, we want two technologies that are not very sensitive, and I believe that GM will not skimp on these two technologies, they are the production technology of long-life bead spindles for aero engines."

As soon as he finished talking about the first project technology, Brown was not calm, this guy actually wanted engine spindle production technology and long life, which is a bit strange.

It is not very difficult to produce a spindle, and the simplest one can turn a spindle as long as there is a bar stock and a lathe, but the problem is that this spindle has almost no value.

Speaking of a spindle alone, in fact, Southwest Science and Industry itself can also be produced, and it is acceptable to use, in the military aviation engine of the Republic, due to the low requirements for life, the spindle and the entire engine can be scrapped at the same time.

Take the turbofan 10 produced by Southwest Science and Industry as an example, after more than 1,000 hours, the entire engine can be scrapped directly.

It seems that the life of the turbofan 10 engine is much longer than that of the previous turbojet 7 engine, but this is not a little worse than the life of the international mainstream aero engine, and there is no comparison with the mainstream civil aviation engine.

A simple comparison with the mainstream foreign commercial aircraft engine CFM56 will find that the life of a CFM56 engine can break the record of 10,000 hours.

Compared with the more than 1,000 hours of life of the turbofan 10 engine produced by Southwest Science and Industry, it seems that the turbofan 10 engine is more than ten times behind others.

The reason for this is that the turbofan 10 engine itself is a military engine, but for the sake of high performance, cost and other considerations, the normal service life is indeed lower than that of civilian engines.

But this impact is not great, what really stretches the life of the Republic engine and the Western aero engine is that the Western aero engine spares no expense in the manufacture on the one hand, using a lot of high-end materials and complex processing processes.

On the other hand, the engine design ideas of foreign people are different from those of the Republic, especially in civil aviation engines, foreign engines adopt unit design.

The entire aviation engine was designed into more than a dozen units. Each unit is a single unit that can be quickly replaced, and all components in the entire unit are designed to last the same life.

As long as the time is up. The unit was going to be replaced and the whole engine could continue to work. Due to the difference in the service life of each unit, it is necessary to think of various ways to fully drain the oil and water of the engine.

There is a big difference in the life of each unit in an engine, for example, the life of unit A is 2,000 hours, but the life of other units B, C and D is 3,000, 3,500 and 4,000.

In order to fully use up the life of all single units, this can only replace the A unit with a new one, and then continue to put it into use. The life of units A, C, and D has not yet reached the end of life, so there is no choice but to continue to replace unit B and continue to put it into use.

In this way, it can be used until the whole engine unit happens to be at a more appropriate point in time, and then the whole engine can be said to be scrapped.

This more suitable time point is the common multiple of the life of more than ten single selectors, and this common multiple is the most economical service life.

In this way, the engine that is constantly replaced by a single body is naturally very long, and the engine is really calculated in the entire life cycle, and the first unit has long been scrapped in the consumption of time.

The longest unit life of an engine is only three or four thousand hours. In the end, the engine is used until it is scrapped, and it has long been a matter of fact.

Saying that this is an engine, in fact, except for the factory number of the engine, 90% is no longer the original product when it left the factory. So, here it is necessary to say that the aero engines of the West are all false longevity.

Everything is a matter of using the unit design, and Yang Hui admits that the industrial technology of the West is developed. The industrial products manufactured are better and have a longer life than those made by the latecomers of the Republic, but this is not as boasted in the rivers and lakes.

Simply compare the time when the engines of both sides were finally scrapped. Then he crudely concluded, "Oh, look at it." The Western industry is awesome, and the engine life is ten times that of the Republic's engine. ”

This is the result of the combination of different methods of life control of twin-engine aero engines and the actual industrial gap.

At this point, one has to ask: then why does the republic not use Western standards for the control of the life of aircraft engines for calculations?

This has to face the reality, the reason why people in Western countries use this method is because they want to design civil aero engines, the competition is large, and they need to make the life of their aero engines longer.

In addition, the life of each unit is indeed longer than the life of the parts made by the Republic, and the same unit design, the life of your parts is smaller, and the common multiple of the small number is naturally smaller, closer to the original life of the parts, and it may only be the life of the longest life unit itself.

However, because the cell body in Western countries has a longer life span and a larger number, the common multiple is even larger, and even the life span of the longest-lived cell is twice as long.

This is not a technical generation gap, just a mathematical problem, after using this method, the engine with a small difference in life can be artificially raised to a large gap.

This is the trick used by Western countries, all because people want good data, so they invent this kind of thing. The republics and the Soviet Union are typical pragmatists, and engine products are not very oriented to the civilian market, even if the method of falsely enlarged life is not very meaningful with the use of unit design.

In addition, the original design idea of the engine is different, for example, the Soviet Union requires low cost, and people think that an aircraft can only survive a maximum of 1,000 flight hours in the war, so it is natural to control the cost, and the life requirements are not high anyway.

The republic was again a division of the Soviet Union, and when it had not yet stepped out of its own style, there was naturally a shadow of the Soviet Union in all aspects, and the engine naturally had a short life.

Now it is different, Yang Hui wants to take a new path, especially in the southwest science and industry to develop to civil aero engines in the future, and naturally has to embark on the road of single-choice design in the West.

Now the problem is that if the life of each single body is still the same as the old republic, the actual life of each single body is not long, you just want to use the single body design to decorate the life data of the engine.

In a word, if you want to use the tall unit design idea, you must have one or two single-choice bodies that have a very long life, and only in this way can the life of the engine be artificially extended.

This is why Yang Hui wants engine spindle manufacturing technology, and why he adds a long life requirement.

These are all the tricks in the design of Western aircraft engine manufacturing, and Western countries say every day that communism is strong in brainwashing, and they look very closely at propaganda.

But in fact, it is precisely the Western countries that really attach great importance to propaganda, and they always use all kinds of tricks to deceive the public.

Not to mention, people's deception skills are really clever, they can always come up with all kinds of tricks, and people can't find thorns when they see it!

Since you can't find a thorn, then you can only do things according to the rules of Western countries, after all, you are going to enter the traditional advantageous field of others, and all the rules have been set by others a long time ago.

Now Brown doesn't know that Yang Hui's heart is crackling with various small abacus, and he doesn't know that a long-life spindle production technology can make Southwest Science and Industry achieve such a big breakthrough.

Brown and even everyone didn't expect Yang Hui to be so cunning, in his eyes, the unit design idea, I'm afraid the Huaxia Republic has never heard of it, let alone actually use it.

I didn't think too much, naturally Yang Hui proposed a long-life spindle manufacturing technology disagreed, the big deal is to improve a little bit of the life of the Republic of aero engines, in the Republic of the current engine life calculation method, the impact of the long-life spindle is not too big.

So, Brown almost didn't take a few minutes to make a decision: "The spindle manufacturing technology can be given to you, but it can only be the single-rotor spindle manufacturing technology, if it is a double-rotor spindle manufacturing technology, this is a different algorithm!" ”

Hearing this, Yang Hui was convinced, he had never seen such a brazen person, and now the international mainstream is a twin-rotor engine, and the general single-rotor engine spindle manufacturing technology is used, what is the point of this.

It may be able to inspire Southwest Science and Industry and improve the aero engine spindle manufacturing technology of Southwest Science and Industry, but this is far from enough, and the long-life twin-rotor engine spindle manufacturing technology must be in hand.

"It's absolutely not going to work, you have to have a spindle with a two-rotor design, and it doesn't make sense to have a single rotor!" (To be continued.) )
