Regarding Lin Hongfei's visit to Russia at the invitation of the Tupolev Design Bureau and the Soloviev Design Bureau, the Ministry of Foreign Affairs and relevant state departments did not set up any obstacles, on the contrary, all departments fully cooperated.

This time, the damned Americans and Europeans did not do things in a proper manner, and even dared to meddle in the telecommunications industry of the republic, and even dared to use this method to coerce the enterprises of the republic.

Everyone understands what Lin Hongfei means: It is naturally good to be able to get a little good things from the Russians, even if you can't get good things from Lao Maozi, but it is good to take the opportunity to warn the Europeans and Americans, and by the way, to lower the prices of the A320 and Boeing 737, the country's foreign exchange reserves are very small, and it can spend a little less.

But this matter, the country is not easy to come forward, although everyone understands that Lin Hongfei must have the factor of state support for doing this, but if the country does not come forward and does not speak, there is room for things to turn around, if the country also comes forward, then things will be bad, for example, now, to Russia, there are no officials from the Civil Aviation Administration at all, all of them are people from Guqi Provincial Industrial Manufacturing Co., Ltd.

————————————————————————

Lin Hongfei and his entourage who took a special plane to Russia, the first stop of the visit was the Tupolev Design Bureau, this time, not only the Kremlin sent a commissioner to accompany them, but also the chief designer of the Tupolev Design Bureau. Tupolev even tried his best to sell their TU-154 to Lin Hongfei...... Apparently, the Russians have already tasted the sweetness of this matter from the transfer of TU-134 aircraft.

Facing Alexey. Lin Hongfei didn't buy Tupolev's sales pitch, he shook his head apologetically, "I'm sorry, Mr. Tupolev." To disappoint you, the TU-154M is indeed a good aircraft, but this aircraft does not satisfy me in many aspects of design, and it leaves a lot to be desired in terms of ease of maintenance. In addition, the tail three releases of the TU-154 are really ......"

Lin Hongfei shook his head, and had nothing to say: the layout of the tail three shots, which god came up with a strange idea at that time? Didn't this guy design the plane with the center of gravity in mind? Or did he feel that all three engines were placed in the tail section, and the tail section was heavy, which was conducive to the plane lifting the nose wheels during takeoff?

Lin Hongfei didn't say nonsense, for example, many wire interfaces on TU-154 do not have an anti-misplugging design, it is a square interface. You can insert it when you are inserting it, you can insert it when you insert it backwards, and you can insert it diagonally...... Every time you do maintenance with this excuse, it's the biggest headache for the maintenance staff, because you're not sure if you've got the connector right. However, once the wrong connector is connected, it is easy to have a serious flight accident. In the previous TU-154 series of aircraft in the more serious flight accidents. There are several cases for this reason.

The problem of the interface is only one of the reasons, and another very serious problem is the inconvenience of maintenance, such as the Boeing 737 and Airbus A320 with carrying capacity and TU-154 aircraft in the same grade, and the main maintenance points have special maintenance windows, which is very convenient, but TU-154 is very insufficient in terms of humanization. Sometimes maintenance personnel need to drill in and out of the interior like a mouse, not to mention that the maintenance efficiency is not high, and the work intensity is not small.

The reason why the TU-154M series passenger aircraft were finally retired from the civil aviation of the Republic was not because of the poor safety of this aircraft. It's not a take-off trembling or anything, the real reason is that the Russians' after-sales service can't keep up, and the spare parts and consumables needed for the flight of the aircraft can't keep up, resulting in the plane lying on the ground and unable to take off, which is the fundamental reason why TU-154 was launched in large numbers from the civil aviation system of the republic.

"Yes yes, we have recognized the problem, and now we are working on improvements," Alexey said. Tupolev nodded again and again, his expression was very sincere, "Now we are developing a new generation of models on the basis of the TU-154M: TU-154M2, TU-154M2 is an aircraft that we have improved after learning some previous experience and lessons...... Speaking of which, Alexey . Tupolev smiled a little smugly, "Although the TU-154M2 is an upgraded version of the TU-154M, the entire aircraft is almost completely new, and it can be considered a completely new model." ”

“TU—154M2？” Listen to Alexey . When Tupolev said this, Lin Hongfei couldn't help but be stunned for a moment, "Why didn't I remember that the Tupolev Design Bureau still had such an aircraft?" ”

Of course, this is actually a very euphemistic statement, and the real statement should be: your Tupolev Design Bureau still has money for new aircraft? It's just that these words are too ugly to hear, and Lin Hongfei naturally won't make such a naïve mistake.

The meaning of Lin Hongfei's words, Alexey. How could Tupolev not be able to hear? He smiled awkwardly, "We have just completed the construction of the model of the TU-154M2, but we are now experiencing some difficulties in terms of funding." ”

It turned out that he was going to pull himself to invest, and Lin Hongfei finally understood Alexey. Tupolev meant, smiled and nodded, but did not speak.

Old Man Ma came with Lin Hongfei this time, and when he heard this, his eyes immediately lit up, and he asked, "Since this is the case, then what about you do a good model?" Can we take a tour. ”

"Absolutely." Alexei. Tupolev was overjoyed, he was afraid that Lin Hongfei and others would not be interested in the improved TU-154M2, if that was the case, he would be in trouble, since they were interested in this, it was naturally all good to say, he picked up the walkie-talkie and said, "Prepare a car, our friends of the republic are going to the No. 3 Research Institute." ”

Lin Hongfei frowned slightly, but the matter had come to this point, it was useless to say anything else, hesitated, and still didn't say anything...... In the same way, he was a little curious, what kind of aircraft is this TU-154M2, which he has never heard of?

…………………………………………

"This is the TU-154M2 you developed?" In the No. 3 research institute of the Tupolev Design Bureau, Lin Hongfei looked at the full-scale model of the aircraft in front of him and was extremely surprised.

The TU-154M2 in front of him has somewhat subverted Lin Hongfei's cognition, this aircraft, oh, no, it should be said that this full-scale model has basically lost the appearance of the TU-154 series aircraft, and the iconic high flat tail of the TU-154 series aircraft is also gone, using the same conventional low flat tail as the Airbus A320 and Boeing 737 series aircraft; Even the iconic tail three-engine layout is missing, replaced by two large-bypass ratio engines that are in line with today's international mainstream and hang under the wings...... The Russians even came up with a large bypass ratio engine with high thrust? Lin Hongfei was a little surprised.

According to the size of the engine, the engine is not D-18T, D-18T is larger; Nor is it D-36, D-36 is not so large, what is it?

"This is the latest engine D-90A of our Soloviev Design Bureau," taking this opportunity, Pillm, the chief designer of the Soloviev Design Bureau, came forward to introduce Lin Hongfei, "The fan diameter of the D-90A engine is 1.9 meters, the bypass ratio is 4.8, the maximum thrust can reach 171KN, and the thrust of two D-90A engines can reach three D-30KU engines, which is the main engine of the next generation of our Soloviev Design Bureau." ”

It seems that the Soloviev Design Bureau is also trying to sell the D-90A engine to Lin Hongfei, and it is really hard to introduce it at the moment, "Compared with the D-30KU engine, the weight of the D-90A engine has only increased by less than 500 kilograms, but the maximum thrust has increased by 70%, and after the wing structure is enhanced, it can be completely hung under the wing, just like the Airbus A320 and Boeing 737." ”

Sure enough, listening to what Pierm said, Lin Hongfei suddenly became interested: D-90A? If I'm not mistaken, it should be the later PS-90A, right? Boss Lin immediately asked Pyrm with great interest, "Mr. Pierm, can you introduce this D-90A engine to me in detail?" Well, especially the process of R&D. ”

"Of course, of course," Lin Hongfei is interested in D-90A, Pillm naturally can't ask for it, although the issue of technology transfer is not considered, but there is no problem at all to sell, "D-90A was first developed in 1979, in 1984 began to test the car, in 1987 for flight test, in 1991 through the national test, in March 1992 to obtain the airworthiness certificate. By the beginning of '93, it had accumulated more than 20,000 hours of operation without major breakdowns, proving that this was a very reliable engine, and a major modification was made in the first half of last year. ”

"Modification?" Lin Hongfei's brows furrowed obviously, as if he was very puzzled by this modification.

Seeing Lin Hongfei's expression, Pirm's heart suddenly trembled! There is no way, the current Russian military aviation industry is fine, the civil aviation industry is too hard, busy explained, "mainly the Fujian and pipeline of the engine have been adjusted, the original engine accessories and pipeline arrangement is a bit disorderly, not conducive to maintenance, the purpose of the change is to improve reliability and maintainability."
