At this time, I remembered that I had a joint development with me? Lin Hongfei shook his head and said with regret, "I'm sorry, our company's financial pressure has been a bit high recently."

Lin Hongfei knew very well that the current Ai22 is still a semi-finished product, so the joint development is nothing more than the poor Ukrainians who sold their underwear and hope to complete the development of Ai22 in this way, and to find a long-term customer for this engine. If he participated in the joint development of this engine, would he not purchase this engine at that time? Obviously it is impossible.

Although the engine is always used, Lin Hongfei doesn't like being plotted like this.

Yatzke, Pavel and Victor were stunned: Lin Hongfei actually refused?

This is a situation that Ukraine never expected before coming. Lin Hongfei was anxious to get the ai22 before, which made the Ukrainians think that when he revealed that he was interested in jointly developing the ai22 engine with him, even if Lin Hongfei was not ecstatic, he would be very surprised. Why did this guy suddenly refuse? This is unreasonable!

"Why?" Pavel couldn't help asking, "It doesn't cost much, it only costs a few million dollars this year."

Given the generous manner of Guqi Industrial Manufacturing Co., Ltd. on the d36 project, in Pavel's view, millions of dollars are not a problem for Guqi Industrial Manufacturing Co., Ltd.

"Our company is under great financial pressure." Lin Hongfei said to Pavel sincerely. "Mr. Pavel may not know what cooperation agreement I have reached with your country. 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 stunned and couldn't help but turn his head to look at Yatzke: Isn't Lin Hongfei talking nonsense?

Lin Hongfei is right in front of him at this moment. Yatz, of course, can't say that Lin Hongfei is talking nonsense, and nodded with a wry smile, "Yes, Mr. Lin and Ukraine have reached some investment agreements, but Mr. Lin, I don't think this 5 million US dollars can put a lot of pressure on you."

"We are just a company. US$5 million is of course nothing for a country, but for a company, even a large international company, it may become the straw that crushes them." Lin Hongfei shook his head, obviously disagreed with Yatzke's words, "Mr. Yatzke, or Ukrainian zhèng Fu can afford this expense?"

"Mr. Lin, you are such a joke. Haha." Yatzko was choked to death by Lin Hongfei, and finally got angry and smiled embarrassedly. "Who doesn't know that your company has money?"

"Does our company have money? I don't think so." How could Lin Hongfei miss this great opportunity to cry for poverty? He frowned and thought for a while, saying, "If I remember correctly, the total temperature of the turbine in Ai22 is only more than 970 degrees? I remember similar products in the United States. For example, the total temperature of the turbine in CF343 of General Electric has reached more than 1300 degrees? This, Your Excellency Minister."

Speaking of this, Lin Hongfei shook his head. Even the fool understood the meaning of this sentence: Do you really think that I am a tight money and don’t want to jointly develop with you? You are so naive. The reason why I am unwilling to jointly develop with you is because your ai22 has too low technical content.

Yatzko was a little embarrassed.

The total temperature in front of the turbine is an important performance indicator of an aircraft engine. A higher total temperature in front of the turbine means higher engine efficiency. When other parameters are the same, a higher total temperature in front of the turbine can bring higher engine thrust. The total temperature in front of the turbine of the AI22 is indeed not high. This is also the reason why Ukraine wants to fool Lin Hongfei: they hope to fool Lin Hongfei, a stupid guy with a lot of money, not only find a rich Kaizi, but also find a big customer for the Ai22 engine produced in the future. For Ukrainians, their first choice is of course Lin Hongfei pays for them to conduct research, but they also understand that this is the most ideal situation. Lin Hongfei should not be so idiotic. Now, Lin Hongfei uses this method to express his dissatisfaction.

"Yes, the total temperature in front of the ai22 is indeed a little lower, and compared with the cf343, not only is the total temperature in front of the turbo is much lower, but the total boost ratio is also much lower than that of cf343." To Lin Hongfei's surprise, after being stimulated by himself, Yatz actually quickly calmed down and talked to Boss Lin. "But even the total temperature in front of the ai22 is only 973 degrees Celsius, which is more than 300 degrees Celsius than cf343.

, the total boost ratio is only 19.6, which is lower than 21 of cf343. However, in front of our turbine, the total temperature, total boost ratio, fuel consumption level and noise level are all lower than cf343. At the same time, it can also make greater thrust than cf343. This shows that the ai22 is actually an engine with great potential. As long as we make persistent improvements to this engine, I believe this is an engine that can cover 4,000 kg to 10,000 kg of reasoning."

After saying that, he paid attention to Lin Hongfei's expression change with a nervous look on his face.

Since we can't convince Lin Hongfei with other things, the best way is to let Lin Hongfei see the huge potential of this engine. To be honest, Yatz really doesn't want to do this. They just want to jointly develop ai22 with Lin Hongfei, and they have no intention of developing ai22 subsequent engine with Lin Hongfei, but the reality forces Yatz to make a choice.

It would be fine if there was no hope. Whether it was Ukraine's Zhèng Fu or Zaporos Progressive Machine Manufacturing Bureau, they might give up the hope of developing the AI22, but there was clearly hope in front of them. In order to seize this slim hope, neither Yatz nor Pavel could care about so much. Of course, the technology outflow of engines of the D18t level is strictly prohibited, but the AI22 is just a small thrust turbofan engine. Even if it is unable to obtain market access in Europe and America, it would be nothing even if it was given to the Chinese.

It seems that this is the same reason. Lin Hongfei has to admit that he was moved by Yatz: That's right, since the total moderate and total booster ratio in front of the turbine can be emitted more than CF343, if the booster ratio and the total temperature in front of the turbine are increased, the performance improvement of the Ai22 must be expected: Not to mention too much, even if the total temperature in front of the turbine is increased to about 1,100 degrees Celsius, even if the total booster ratio remains unchanged, the maximum thrust of this engine can reach at least 5,000 kilograms?

"I'll think about it." After pondering for a long time, Lin Hongfei finally gave an ambiguous answer. "Let's see if you can think of some ways to get some money."

Yatzke, Victor and Pavel were relieved: As long as Lin Hongfei considers the reasons, there is great hope for this matter. As for what Lin Hongfei said, "think about a way to get some money", it was directly understood by Yatz and the other three as Lin Hongfei's words for what Lin Hongfei said just now. After all, Lin Hongfei just said that he had no money, so he couldn't take out the money immediately? Even if everyone knows what happened, he still has to take care of his face. He nodded repeatedly and said, "We understand, we can fully understand."

"But what is the statement about this joint development? How are the progress, patents, R&D funds, and production arranged? Let me first say that, I hope this "joint development" can have enough sincerity, not verbally. "Since you are optimistic about the potential of ai22, Lin Hongfei naturally needs to learn as much details as possible, and at the same time give the Ukrainians a shot of vaccinations to avoid these Ukrainians having any other ideas. "Also, Mr. Victor, what is the improvement plan you designed for our Yunqi 200a? Can you tell me a general idea?"

"About this joint development, our idea is like this." Pavel coughed lightly, trying to suppress his joy in his heart, and said, "According to our calculations, if sufficient R&D funds can be used to ensure this sufficient funding, the first batch of test-installation machines can be assembled within two years, and the final finished products can be produced within three years. Our idea is that all patents of ai22 and subsequent engines will be shared by the joint development party. In terms of R&D funds, Ukraine bears part of it. As the patent sharing party, you bear most of the R&D funds; as the production, mainly Sichi Engine Company, of course, some parts that your company or your country can produce can also be handed over to you for arrangements."

After saying that, Pavel looked at Lin Hongfei carefully, hoping to get an answer from Lin Hongfei's face.

But Lin Hongfei disappointed Pavel. There was no change in his expression on his face. He just nodded, and he couldn't tell what he was thinking. Then he turned his head and looked at Victor, waiting for Victor's answer.

"Haha, our idea 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 a layout of two engines hoisting under the wings. If you follow Mr. Lin's requirements, use a supercritical wing shape and optional winglet winglets, our preliminary calculation results are that it only takes about $15 million to complete the design and testing work."

After saying that, Victor looked at Lin Hongfei carefully, waiting for Lin Hongfei's reaction.

"Cough" also coughed, and Lin Hongfei spoke (to be continued...
