"Wow~~"

As soon as Lin Hongfei said this, all the reporters, including the leaders, couldn't sit still.

In the early 90s, reporters are still a more professional and dedicated group, although many reporters are not aviation reporters, but in order to participate in today's press conference, before coming we still made up some relevant knowledge of aero engines, naturally know the importance of the core machine, the Republic of China in the aero engine is not good, the most important thing is that the core machine is not good, and the core requirements of the core machine are to be able to withstand a series of harsh conditions of high temperature, high pressure and high centrifugal force.

Our country's aviation industry can produce the core machine, but can not produce the core machine with high-tech technical content, as far as the overall technical content is concerned, the technical level of China's aero engine is still equivalent to the international technical level of the late fifties and early sixties, but suddenly increased by 200 degrees Celsius, if the performance of other aspects can also achieve this degree of leapfrogging, this is almost equivalent to one step into the international technical level of the early 80s...... This is a personal life!

It's no wonder that Lin Hongfei was so confident just now and dared to let out such wild words.

"In order to reduce the weight of the blade as much as possible without sacrificing its performance and strength, we have adopted the superplastic forming plus diffusion welding process." Speaking of this, Lin Hongfei raised the blade, which was not as big as a palm, and pointed it at the camera.

The cameraman on the scene is a photographer with more than 20 years of work experience who was specially transferred from CCTV, and he is one of the live broadcast photographers of the CCTV Spring Festival Gala in recent years.

"Is this the construction of the turbine blades of the core engine of an aero engine?" Looking at the internal structure of the blade projected on the large projection screen next to it in the shape of a flattened W, a reporter muttered in a low voice. For the first time, they learned that the internal structure of the leaf was like this.

Although they couldn't see the difference between these shimmering metallic turbine blades and turbine blades made of other alloys, just this action made everyone subconsciously believe Lin Hongfei's words: If it wasn't true, how could Lin Hongfei show it to everyone so grandiosely?

Invisibly, Lin Hongfei's confident action immediately made everyone think that his words were very credible, but the faces of those reporters from foreign media became a lot more ugly, and they exchanged glances with each other vaguely: It's not the same as what they think.

"As for this ......," Lin Hongfei put down the palm-sized high-pressure turbine blade of the core machine in his hand. Pick up a huge blade that is a few points longer than Lin Hongfei's arm, the blade seems to be a little heavy, Lin Hongfei needs to use two hands to hold it smoothly, "This is the front blade of the turbofan engine that we can produce and master the technology at present, that is, when we make civil aircraft." You can see the fan blades of the engine, the size of this blade is 80 cm. It can be used to make turbofan engines with large bypass ratios between 4.8 and 5.8. ”

This is the fan blade for making a turbofan engine with a large bypass ratio? Lin Hongfei revealed this information. There was another low exclamation.

As we all know, the bypass ratio of the Spey MK202 military engine we imported from the United Kingdom is only 0.62, but the bypass ratio of the most widely used civil aviation engines represented by the V2500 series and CFM56-5B series is more than 4.5, and even the bypass ratio of the high-thrust military turbofan engine used on large transport aircraft is mostly above 4.5...... Even the bypass ratio of the former Soviet Union's D-30K series turbofan engine with a small bypass ratio is 2. But to date, the turbofan engine with the largest bypass ratio we've been able to produce is only 1.74, well, or the turbofan 6A that has been dismounted.

But now. Does that mean we already have the capacity to produce turbofan engines with large bypass ratios around 5?

As soon as the idea came to mind, the reporters were immediately excited.

"Yes, in terms of the difficulty of technical implementation, it is not big," Lin Hongfei smiled and nodded in the face of this question raised by the Xinhua News Agency reporter in an excited tone, "Our company has now mastered the production and manufacturing technology of the D-30K series turbofan engine of the Russian Soloviev Design Bureau with a bypass ratio of 2, and there are not many major core problems, I have seen the company's schedule in aero engines, and the imitation D-30 and D- The prototype of the 30K series engine will be completed around the beginning of '86, and the turbofan engine with a larger bypass ratio is expected to produce an engineering prototype within 10 years. ”

"...... Uproar"

As soon as Lin Hongfei said this, the reporters at the scene were stunned at first, and then clapped their hands crazily with tears streaming down their faces, many reporters' hands were red, but they seemed to be unconscious, crying wildly, while clapping desperately, as if only in this way could they express their inner excitement.

Yes, they are indeed excited, and they have reason to be so excited, although the aviation industry of the Republic has been stagnant and even regressing for various reasons over the years, but as an ordinary person, of course, everyone hopes that their country has a strong aviation industry, which will support a strong protective barrier for the country's blue sky, and also hope to use civil aviation aircraft equipped with domestic advanced engines to carry the civil aviation industry of the Republic.

But the reality of the situation is to tell them that this is simply impossible, and the disappointment again and again has made everyone's hot heart cold, but today, in the case of no one being prepared, Guqi Provincial Industrial Manufacturing Co., Ltd., which has brought everyone surprises again and again in the automobile industry, actually gave them such a big surprise.

"Mr. Lin, what did you say...... It's all true? A CCTV reporter who had just cried and couldn't look like he wiped away his tears and asked Lin Hongfei with red eyes, "Can we really see our own high-thrust turbofan engine within 5 years?" Is there hope that in 10 years we will see our own large-bypass ratio turbofan engines? Also, are these core parts produced by your company in an industrial production way? ”

"It's not." Lin Hongfei shook his head.

With Lin Hongfei's shaking of his head, many people's hearts sank: Isn't it?

I only heard Lin Hongfei continue, "These things are all produced in the laboratory when we are studying blades, turbine disks, aluminum-lithium alloys and other technologies. ”

Lin Hongfei looked at this reporter, and sighed in his heart: In fact, these people are the group of people who really support the republic, holding back the excitement in his heart, Lin Hongfei continued, "I believe everyone knows that our company has spent a lot of money to introduce the technology and patents of D-30 and D-30K series engines from the Russian Soloviev Design Bureau, and our company has spent so much money and so much energy to do these things, and it is definitely not to throw money into the water to play, don't you say?" ”

But the reporter was obviously stimulated by the previous disappointments again and again, and still hesitated, "But those companies under AVIC ......"

"What about AVIC, we don't care about them, I ask you, before our Guqi Provincial Industrial Manufacturing Co., Ltd. settled in the automobile industry station, what was our national automobile industry like? Now our national automobile industry doesn't dare to say that it stands up, at least it has seen the dawn," without waiting for this old man to finish speaking, Lin Hongfei interrupted him and asked, "Since our Guqi Provincial Industrial Manufacturing Co., Ltd. can work hard in the automobile industry, why can't we achieve a miracle in the aviation industry?" ”

As soon as Lin Hongfei's words were finished, a burst of thunderous applause sounded like a storm......

"Hongfei, these things ......" Dongfang Xiaoling, who had been waiting for Lin Hongfei in the background, saw Lin Hongfei, who was walking a little heavily after the end of the press conference, hesitated a little, hesitated, and asked Lin Hongfei in a low voice, "Didn't the relevant technical materials come back from Russia?" When were the samples produced? ”

"We didn't produce it." Without outsiders, the smile on Lin Hongfei's face disappeared, replaced by a heavy face.

"Didn't we produce it?" Dongfang Xiaoling didn't expect that what she heard was such an answer anyway, so she was stunned for a moment, and after a moment's pause, she asked eagerly, "What the hell is going on?" ”

"These are all things that we have dealt with after we got them back from Russia, Belarus and Ukraine," Lin Hongfei took a deep breath and said with a wry smile, "We need to give others a confidence, and we also need to send a wrong signal to the West......

I see! Dongfang Xiaoling finally understood: it turned out that today's press conference was a scam at all!

However, the relevant technical data is still in the stage of verification of authenticity, how can it be possible to produce a finished product? Even if it is produced in the laboratory at any cost, it is impossible, Dongfang Xiaoling had such a doubt in her heart before, and now she finally understands.

"But will they be fooled?"

"Maybe, maybe not, but I believe that even if they didn't send the media to interview them, they should have paid close attention to this press conference, you say, when they watched this press conference, could it be that they didn't have any doubts in their hearts?"

So that's it?! Dongfang Xiaoling suddenly realized, and twisted Lin Hongfei's waist fiercely, "It's so cunning!" Say, do you often lie to me like that? ”

"Madam, wronged!" The soft flesh on his waist was suddenly attacked, and Boss Lin couldn't help but scream. (To be continued......)
