At this time, you want to develop it with me? Lin Hongfei shook his head and said with a regretful face, "I'm sorry, our company's financial pressure has been a bit ...... recently."

What is the joint development, Lin Hongfei is very clear, the current AI-22 is still a semi-finished product, so the joint development is nothing more than the poor Ukrainians who have sold their leggings hope to complete the development of AI-22 in this way, and by the way, find a long-term customer for this engine, if you participate in the joint development of this engine, can you not purchase this engine at that time? Apparently impossible.

Although the engine is always used, Lin Hongfei does not like to be so calculated.

Yatsko, Pavel and Victor were stunned for a moment: Lin Hongfei actually refused?

This is a situation that Ukraine did not expect before coming, Lin Hongfei was anxious to get AI-22 before, which made Ukrainians think that when he revealed the news that he intended to jointly develop the AI-22 engine with him, Lin Hongfei would be pleasantly surprised even if he was not ecstatic, why did this guy suddenly refuse? This doesn't make sense!

"For what?" Pavel couldn't help but ask, "It doesn't cost much, it only needs a few million dollars this year......"

With the generosity of the Guqi Provincial Industrial Manufacturing Company Limited on the D-36 project, in Pavel's view, a few million dollars is not a problem for the Guqi Provincial Industrial Manufacturing Company at all.

"Our company's financial pressure is very high," Lin Hongfei said to Pavel very sincerely, "Mr. Pavel may not know what cooperation agreement I have reached with your government, what I need to tell you is that our company needs to inject hundreds of millions of dollars into your country every year, which is a huge test for any company." ”

"Hundreds of millions of dollars?" Pavel was dumbfounded, and couldn't help but turn his head to look at Yatsk: Lin Hongfei isn't talking nonsense, right?

Lin Hongfei was in front of him at the moment. Of course, Yats couldn't say that Lin Hongfei was talking nonsense, and nodded with a wry smile, "That's right, Mr. Lin and our Ukraine have reached some investment agreements, but Mr. Lin, I don't think this $5 million can put much pressure on you......"

"We're just a company, and $5 million is certainly nothing for a country, but for a company, even if it's a large international company, it can be the straw that crushes them." Lin Hongfei shook his head, obviously disagreeing with Yatzko's words, "Mr. Yatsk, or can the Ukrainian government afford this expenditure?" ”

"Mr. Lin, you are kidding. Hehe...... "Yatzkoden was choked half to death by Lin Hongfei, and it was easy to calm down." He laughed wryly. "Who doesn't know that your company is rich?"

"Is our company rich? I don't think so, "Now this great opportunity to cry poor, how can Lin Hongfei miss it?" He frowned and thought for a moment, and said, "If I'm not mistaken, the total temperature in front of the turbine of the AI-22 is only more than 970 degrees, right?" I remember the American analogue. For example, the total temperature before the turbine of General Electric's CF34-3 has reached more than 1,300 degrees? This, Your Excellency ...... Minister"

Speaking of this, Lin Hongfei shook his head, the meaning of these words is almost understandable to even a fool: Are you really unwilling to jointly develop with you because of money constraints? You guys are so naïve. The reason why I am reluctant to jointly develop with you, young master, is only because the technical content of your AI-22 is too low.

Yatsk was suddenly embarrassed.

The total temperature before the turbine is an important performance indicator of the aero engine, a higher total temperature before the turbine means higher engine work efficiency, in the case of the same other parameters, a higher total temperature before the turbine can bring higher engine thrust, the total temperature before the turbine of AI-22 is indeed not high, which is also the reason why Ukraine wants to fool Lin Hongfei in: they hope to fool Lin Hongfei, a guy with a lot of money, not only to find a rich Kaizi, but also to be able to produce AI in the future— 22 engine to find a big customer...... For Ukrainians, their first choice is, of course, Lin Hongfei to pay for their research, but they also understand that this is the most ideal situation, Lin Hongfei should not be so idiotic, and now, Lin Hongfei uses this way to express his dissatisfaction.

"Yes, the total temperature before the turbine of the AI-22 is indeed a little lower, and it is indeed a lot lower than that of the CF34-3, not only the total temperature before the turbine is much lower, but even the total boost ratio is much lower than that of the CF34-3," to Lin Hongfei's surprise, after being stimulated by himself, Yatzke quickly cleaned up his mood and talked to Boss Lin, "But even if the total temperature before the turbine of our AI-22 is only 973 degrees Celsius, which is more than 300 degrees Celsius lower than that of CF34-3, The total boost ratio is only 19.6, which is lower than the 21 of CF34-3, but the total temperature, total boost ratio, fuel consumption level and noise level before our turbine are all lower than CF34-3 at the same time, and it can also make greater thrust than CF34-3, which shows that AI-22 is actually a very potential engine, as long as we continue to improve this engine, I believe this is an engine that can cover 4000 kg to 10000 kg reasoning. ”

After speaking, he paid attention to the change in Lin Hongfei's expression with a nervous expression.

Since there is no other way to persuade Lin Hongfei, the best way is to let Lin Hongfei see the huge potential of this engine...... To be honest, Yatz really didn't want to do this, they just wanted to jointly develop the AI-22 with Lin Hongfei, and they never wanted to develop the AI-22 follow-up engine with Lin Hongfei, but the reality forced Yatz to make a choice.

If there is no hope, it will be enough, whether it is the Ukrainian government or the Zaporosh Progressive Machine Building Bureau, they may give up hope of developing AI-22, but there is clear hope in front of them, and in order to seize this slim hope, neither Yatzko nor Pavel can care so much...... Of course, the outflow of technology is strictly forbidden for engines of this level of D-18T, but AI-22 is just a small-thrust turbofan engine, and even if it is given to the Chinese under the premise that there is no way to obtain market access in Europe and the Americas.

It seems to be the same thing...... Lin Hongfei had to admit that he was moved by Yatske: that's right, since the total pre-turbine temperature and the total boost ratio are lower than CF34-3, they can emit greater thrust than CF34-3, if the boost ratio and the total pre-turbine temperature are raised, the performance improvement of AI-22 must be expected: not to mention, even if the total pre-turbo temperature is increased to about 1100 degrees Celsius, even if the total boost ratio remains unchanged, the maximum thrust of this engine can at least reach more than 5000 kg, right?

"Well, I'll think about it." After pondering for a long time, Lin Hongfei finally gave an ambiguous answer, "Let's see if we can find a way to make some money." ”

Yatsko, Victor and Pavel immediately breathed a sigh of relief: as long as Lin Hongfei considers the reason, there is great hope for this matter, as for what Lin Hongfei said, "think of a way to make some money", it was directly understood by Yatz and the other three as Lin Hongfei's prevarication for what he just said, after all, Lin Hongfei just said that there is no money, so he can't take out the money immediately, right? Even if everyone knows what Lu Dao is all about, but the face still has to be taken care of, and he nodded again and again, "We understand, we can understand it completely." ”

"But what is the name of this joint development? How are the three pieces of progress, patents, R&D funds, and production arranged? "Since he is optimistic about the potential of AI-22, Lin Hongfei naturally has to know as much as possible about some details, and at the same time, he also wants to give the Ukrainians a dozen preventive shots, lest these Ukrainians have any other ideas," Also, Mr. Victor, what is the improvement plan you designed for our Yun-7-200A, can you give me a general explanation?" ”

"As for this joint development, our assumption is this," Pavel coughed lightly, trying to suppress the joy in his heart, "according to our calculations, if there is sufficient R&D funding...... This sufficient financial guarantee is an annual investment of no less than 10 million US dollars...... The first batch of trial machines can be assembled within 2 years, and the final finished product can be produced within three years, our assumption is that all the patents of AI-22 and subsequent models of engines will be shared by the joint developer, and we will bear part of the R&D funds in Ukraine, and as the sharer of the patents, you will bear most of the R&D expenses; As for the production, it is mainly based on the Cice engine company, of course, some parts that your company or the company in your country can produce, you can also hand over to you to arrange. ”

After speaking, Pavel looked at Lin Hongfei cautiously, hoping to get an answer from Lin Hongfei's face.

But Lin Hongfei disappointed Pavel, there was no change in his face, he just nodded, he couldn't see what he was thinking in his heart at all, and then he turned his head to look at Victor, waiting for Victor's answer.

"Ahem...... Our assumption is that in order to reduce the cost of secondary development as much as possible, the basic structure of the new jet Y-7 remains unchanged, and it is still the layout of the upper single wing, low flat tail, and two engines hoisted under the wing, if it is in accordance with your requirements, using supercritical airfoils, with optional winglets, our preliminary calculation results are that only about 15 million US dollars are needed to complete all the design and testing work. ”

After speaking, Victor also looked at Lin Hongfei cautiously, waiting for Lin Hongfei's reaction.

"Ahem......" also coughed, and Lin Hongfei spoke...... (To be continued......)
