Pirm didn't dare to say more on this issue, and hurriedly changed the topic slightly, "Compared with the D-30K series engine, the D-90A engine adopts a lot of mature military engine technology in the design, which is characterized by a large bypass ratio design, 11 unit structure, digital electronic control and mechanical hydraulic backup, low fuel consumption, focusing on reliability and maintenance design, the overall technical level and IAE International's V2500 series, CFM's CFM56— The 5 Series engines have a similar level of technical skills, and the maximum thrust is much higher. ”

The technical level of this D-90A engine is equivalent to the level of V2500 series and CFM56-5 series? Lin Hongfei was deeply skeptical of Pierm's words, but at this moment, obviously not the time to question, Boss Lin nodded with a smile and asked Pierm, "Mr. Pierm, write down when we visit your company, can we visit this D-90A engine?" ”

"No problem! Of course, there are no problems! Hearing this, Pyrem was overjoyed!

Pirm rejoiced, but Alexey . Tupolev couldn't be happier: Lin Hongfei was a guest I invited, and he came to visit our Tupolev Design Bureau. I couldn't help but remind Pirm euphemistically, "Mr. Pirm, it's not too early, should we visit our TU-154M2 as soon as possible?" ”

If it weren't for Alexey . With Tupolev's words, Phelm did not realize that he had already taken over the throne, although he was not afraid of Alexei. Tupolev, but also to give him three points...... When the engine is produced, it will naturally be sold, and if it offends Alexei. Tupolev is a cautious guy, then he will lose more than he gains. Hearing this, he nodded apologetically to Lin Hongfei, "Mr. Lin, we'll talk later." ”

"No problem." Lin Hongfei nodded with a smile, but said to Alexei, who had disturbed his conversation. Tupolev was not so polite, "Mr. Tupolev, I have been preparing for this trip to Russia for a week, and I think I have enough time. Don't worry. ”

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

Alexei. Tupolev's face suddenly felt a little embarrassed.

Fortunately, this guy's skin is thick enough, or rather, the current situation in Russia forces him to have a thick skin. In the face of Lin Hongfei's dissatisfaction, he actually endured it alive. He nodded. With a sincere face, he said, "What Mr. Lin said is that I am anxious, but I need to explain this, I think we can cooperate in many aspects, in this regard." I'm in a hurry. ”

Lin Hongfei admired Alexey a little. Tupolev is this guy, at this time, he can really bend and stretch.

"That's right," Lin Hongfei nodded.

……………………

After walking inside this TU-154M2. Lin Hongfei simply doubted whether he had walked into the cabin of an Airbus A320, with the existing avionics level in Russia, there is no way to achieve a double crew, the cockpit in the front is still a four-person crew driving system, but the crew compartment in the rear makes Lin Hongfei feel unusually familiar: it is simply a copy of the interior and layout design of the Airbus A320.

Because it's just a model, I don't know if the old TU-154M will sound everywhere and the luggage compartment cover will open "automatically" when taking off, but in terms of workmanship and overall layout, and sense of space, this TU-154M2 is really on par with the Airbus A320, plus the Tupolev Design Bureau has made major changes to the overall aerodynamic layout of the aircraft, with the traditional low flat tail and swept wing. The design of the underwing engines and the carrying capacity comparable to the Airbus A320 and Boeing 737, at least in Lin Hongfei's view, if it can really be mass-produced, the current TU-154M2 is enough to pose a serious threat to the Airbus A320 and Boeing 737...... However, at this time, Lin Hongfei was even more puzzled: Why is it in his memory that there will be no TU-154M2 in later generations?

"Mr. Lin, do you have any questions?" Seeing that he had already come up with the best thing, but obviously the best thing did not attract Lin Hongfei and Alexey. Tupolev couldn't help but feel a little anxious in his heart, and couldn't help but ask.

After hesitating for a moment, Lin Hongfei said euphemistically, "Mr. Tupolev, the design of your TU-154M2 is indeed very good, although I don't know how the use of the real machine is good, but in terms of this 1:1 model, it is a very good aircraft, don't you think that the TU-154M2 has some conflicts with the TU-204 in terms of positioning?" ”

TU-204 is the latest generation of 200-seat, medium and long-range large civil airliners developed by the Tupolev Design Bureau, which is intended to replace the current TU-154, TU-204 is infinitely close to Airbus A320 and Boeing 737 in the overall aerodynamic layout, all of which are swept wings, low flat tails, wing underhung engines, and a layout of 6 seats per row in the cabin, of course, according to the Tupolev Design Bureau itself, the competitor of the TU-204 series is not the Boeing 737 series, Rather, it is the Boeing 757 family...... But in fact, there is considerable overlap in the market positioning of the Boeing 737 and Boeing 757.

But now they have come up with an upgraded version of the TU-154M: the twin-engine TU-154M2, this TU-154M2 is very close to the TU-204 in terms of appearance and internal design.

was asked this question by Lin Hongfei, Alexei. Tupolev's heart suddenly burst out!

Of course, the Tupolev Design Bureau will not come out with a TU-204 and then a TU-154M2 with almost completely overlapping market positioning, and they are not burning too much money, and the Tupolev Design Bureau does not have much money to toss now, and the reason for doing so is naturally due to the Tupolev Design Bureau, but this reason is really not for outsiders:

TU-204 is indeed the model planned by the Tupolev Design Bureau to replace the TU-154, but in the specific actual situation, the TU-204 adopts a lot of new technologies, new processes and new materials, which is equivalent to the "advanced version" of TU-154M2, or can be regarded as the "advanced version" of TU-154M, which is roughly equivalent to the span from windows3.1 to windows95 that Microsoft is developing;

However, the technical span between TU-154M and TU-154M2 is not so large, the fuselage design of the aircraft has not changed at all, and the shape of the wing has not changed, but the structure and strength of the wing have been strengthened in order to be able to hang the engine, from TU-154M to TU-154M2, which can be considered an "advanced upgrade".

This can also be seen from the price between the two, the estimated price of a single bare metal of TU-154M2 is 9 million to 10 million US dollars, while the price of a single bare metal of TU-204 is as high as 14 million to 15 million US dollars, which is nearly 50% more expensive than TU-154M2!

"This ......" Alexey . Tupolev hesitated, he didn't expect Lin Hongfei to ask such a sharp question, and he was a little contradictory for a while, but finally decided to tell the truth selectively, and said euphemistically, "The carrying capacity of these two aircraft is comparable, but there is a gap in the technical level, and the technical level of TU-204 is more advanced, with higher technological content, and more applications of new materials and new technologies; The TU-154M2 has applied a large number of existing mature technologies, which can greatly reduce the production and manufacturing costs of aircraft......"

Although what he said was already a little vague, Lin Hongfei was not stupid, and nodded suddenly in understanding.

————————————————————————

What to do? This is a very urgent question in front of Lin Hongfei.

Because of the current economic difficulties in Russia, the Russians are now chasing the dollar as an international hard currency, to the point of madness, and the same is true in this cooperation. Tupolev, the chief designer of the Tupolev Design Bureau, as well as representatives of the Kremlin, repeatedly hinted to Lin Hongfei that they could cooperate in a wider and broader field.

Of course, Lin Hongfei understood the meaning of this hint, it was clearly Lin Hongfei at high speed, 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 negotiable, of course, the price needs to be negotiated.

After an investigation of the TU-204, Lin Hongfei decided to solicit the opinions of many parties.

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

"I looked, the Soviet Union ...... The gap between the Russians and the Americans is still not small compared to the level of skills shown by the Europeans and the Americans," the old man smacked his lips, quite unwilling to accept the situation in front of him, "TU-154M2 and TU-204 are both good civilian aircraft, but they are limited to civilian ......"

As soon as Old Man Ma said this, everyone frowned in unison.

There are still unfinished words in Old Man Ma's words, and everyone naturally understands what these unfinished words mean, but it is this that makes everyone feel a headache. (To be continued......)
