Pilm dared not say much about this issue, so he quickly changed the topic. "Compared with the D-30k series engine, the D-90a engine adopts many mature military engine technologies in its design. Its characteristics are large bypass ratio design, 11 unit structures, digital electronic control and mechanical hydraulic backup, low fuel consumption, and pays attention to reliability and maintenance design. The overall technical level is comparable to that of IE International's V2500 series and CFM's CFM56-5 series engines, and the maximum thrust is much higher."

The technical level of this D-90a engine is actually equivalent to that of the v2500 series and the cfm56-5 series? Lin Hongfei was deeply suspicious of Pilm's words, but at this moment, it was obviously not the time to question it. Boss Lin smiled and nodded and asked Pilm, "Mr. Pierm, remember to remember if we can visit this D-90a engine when we go to your company to visit?"

"No problem! Of course there is no problem!" Hearing this, Pilm was immediately overjoyed!

Pilm was overjoyed, but Alexey Tupolev was not happy: Lin Hongfei is the guest I invited, come to our Tupolev Design Bureau to visit. What is the matter with you, Pilm, holding someone out of the way? I couldn't help but remind Pilm tactfully, "Mr. Pilm, it's getting late, should we visit our tu-154m2 as soon as possible?"

If it weren't for Alexei Tupolev's words, Pilm hadn't realized that he had already taken over the top. Although he was not afraid of Alexei Tupolev, he would have to make him three points... The engine was produced and he would naturally sell it. If he offended Alexei Tupolev, a petty guy, he would have lost it. Hearing this, he nodded apologetically to Lin Hongfei, "Mr. Lin, we'll talk later."

"No problem." Lin Hongfei nodded with a smile, but was not so polite to Alexei Tupolev, who disturbed his conversation with him. "Mr. Tupolev, I have prepared a week for this trip to Russia. I think I have enough time. No one has to worry."

Although Lin Hongfei's tone was very tactful, anyone could hear the dissatisfaction.

Alexey Tupolev's face suddenly felt a little embarrassed.

Fortunately, this guy is also thick-skinned enough, or in other words, the current situation in Russia makes him have to be thick-skinned. Faced with Lin Hongfei's dissatisfaction, he actually endured it. He also nodded and said sincerely, "Mr. Lin is saying that I am anxious, but I need to explain this. I think both of us can cooperate in many aspects, and at this point, I am anxious."

Lin Hongfei admired Alexey Tupolev, who was really able to bend and stretch at this time.

"That's right," Lin Hongfei nodded.

………………………………………

After walking into the inside of this tu-154m2, Lin Hongfei simply wondered if he had walked into the cabin of an Airbus A320. With Russia's current avionics level, it was not possible to achieve a two-person crew. The cockpit in the front was still a four-person crew driving system, but the crew cabin at the rear made Lin Hongfei feel extremely familiar: it was simply copied from the interior and layout design of the Airbus A320.

Because it is just a model, I don’t know if the old tu-154m will ring everywhere and the luggage compartment cover will be "automatically" opened when taking off. However, in terms of workmanship, overall layout and sense of space, this tu-154m2 is really not different from the Airbus A320. In addition, the Tupolev Design Bureau has made major changes to the overall aerodynamic layout of the aircraft, the traditional low flat tail, swept wing. The design of the under-wing engine and the carrying capacity comparable to the Airbus A320 and Boeing 737. At least in Lin Hongfei’s view, if mass production can be achieved, the tu-154m2 is now enough to pose a serious threat to the Airbus A320 and Boeing 737... But at this time, Lin Hongfei was even more confused: Why did the tu-154m2 appear in his memory at all?

"Mr. Lin, what else do you have?" Seeing that he had already taken out the best thing, it was obvious that the best thing did not attract Lin Hongfei. Alexey Tupolev couldn't help but feel a little anxious and couldn't help asking.

After hesitating for a moment, Lin Hongfei said tactfully, "Mr. Tupolev, your tu-154m2 design is really good. Although I don't know how the real machine feels, judging from this 1:1 model, it is a very good aircraft. Don't you think the tu-154m2 has some conflicts with tu-204 in positioning?"

The tu-204 is the latest generation of 200-seat, medium and long-range large civil aviation aircraft developed by the Tupolev Design Bureau. The purpose is to replace the current tu-154, Tu-204 is infinitely close to the Airbus A320 and Boeing 737 in terms of overall aerodynamic layout. Both are swept wings, low flat tails, under-wing engines, and 6 seats in each row in the cabin. Of course, according to the Tupolev Design Bureau's own statement, the competitors of the tu-204 series are not the Boeing 737 series, but the Boeing 757 series... But in fact, the market positioning of the Boeing 737 and Boeing 757 have considerable overlap.

But now they have created an upgraded version of tu-154m: the double-engine tu-154m2. This tu-154m2 is very close to tu-204 in both appearance and internal design. Seeing these two aircraft with almost completely overlapping positioning, Lin Hongfei couldn't help but wonder: What exactly do you Tupolev Design Bureau want to do?

When Lin Hongfei asked this question, Alexey Tupolev's heart suddenly burst into pieces!

Of course, Tupolev Design Bureau will not create a Tupolev Design Bureau that has almost completely overlapping the market positioning after creating a Tupolev Design Bureau. They are not burned with too much money. Tupolev Design Bureau now has little money to make. The reason for doing this is naturally because of Tupolev Design Bureau, but this reason cannot be told to outsiders:

Tu-204 is indeed a model that Tupolev Design Bureau plans to replace Tu-154, but in the specific situation, Tu-204 adopts many new technologies, new processes and new materials, which is equivalent to the "advanced version" of Tu-154m2, or it can be considered a "advanced version" of Tu-154m, and its significance is roughly equivalent to the span from Windows 95 that Microsoft is developing;

However, the technical span between tu-154m and tu-154m2 is not that big. The fuselage design of the aircraft has not moved at all, and the shape of the wing has not changed. It is just that the structure and strength of the wings have been strengthened in order to be able to hang the engine. From tu-154m to tu-154m2, it can be considered an "advanced upgrade version".

This can also be seen from the price between the two. The estimated single-machine bare metal price of tu-154m2 is US$9 million to US$10 million, while the single-machine bare metal price of tu-204 is as high as US$14 million to US$15 million, which is nearly 50% more expensive than tu-154m2!

"This..." Alexey Tupolev hesitated for a moment. He didn't expect Lin Hongfei to ask such a sharp question. There was some contradiction for a while, but he finally decided to tell the truth selectively and said tactfully, "The carrying capacity of these two aircraft is comparable, but the technical level is somewhat different. The technical level of tu-204 is more advanced, and the technological content is higher, and the application of new materials and new technologies is more. Tu-154m2 has a large number of existing mature technologies. These mature technologies and processes can greatly reduce the production and manufacturing costs of the aircraft..."

Although this was a little blurred, Lin Hongfei was not stupid and nodded suddenly.

—————————————————————

What to do? This is a very urgent question facing Lin Hongfei.

Because of Russia's current economic dilemma, the Russians' pursuit of international hard currency such as the US dollar has reached a crazy level. The same is true in this cooperation. Alexei Tupolev, the chief designer of the Tupolev Design Bureau and the representative of the Kremlin, repeatedly hinted Lin Hongfei that everyone can cooperate in a wider and wider field.

Lin Hongfei certainly understood the meaning of this hint. It was clearly Lin Hongfei on the highway. As long as Lin Hongfei was willing to pay, Russia was willing to sell all the technology of the tu-154 series aircraft to Lin Hongfei... Even the latest tu-204 of the Tupolev Design Bureau is not unnecessarily discussed. Of course, the price needs to be discussed carefully.

This matter is very important. After conducting some investigation on tu-204, Lin Hongfei decided to solicit opinions from multiple parties.

"Old Ma, what do you think about this matter?" Lin Hongfei asked the first question, of course, was the Taishan Beidou-level figure in the aviation field in the company, Mr. Ma.

"I looked at the Soviet Union... the technical level shown by the Russians is quite different from that of Europeans and Americans," Mr. Ma smacked his lips, feeling a little unwilling to the situation in front of him. "Tu-154m2 and tu-204 are good civil aircraft, but only for civilians..."

As soon as Mr. Ma said this, everyone frowned.

Is there anything else in Mr. Ma’s words? What does this unspeakable mean? Everyone naturally understands, but it is this that makes everyone feel a headache. (To be continued...)
