The first stop of the Kuznetsov Design Bureau with Chen Geng was the exhibition room of the Design Bureau, and looking at the crystallization of modern industry in the Kuznetsov Design Bureau, Chen Geng drooled wildly, and he had a very strong urge to resist the two to go home -- but it is estimated that the so-called "accompanying personnel" who said that it was the Soviet Foreign Ministry but was very likely the KGB would not agree. Pen, fun, and www.biquge.info

"Mr. Chen, this engine is the most powerful turboprop engine in the world: the NK-12 produced by our Kuznetsov Design Bureau adopts a counter-rotating twin-propeller design, and this engine is mainly installed in the Soviet Union's Tu-95 'Xiong' strategic bomber, AN-22 strategic transport aircraft, and Tu-114 long-range intercontinental passenger aircraft." The diameter of the propeller is enough to be two stories high, and the huge engine said to Chen Geng proudly: "The maximum power of this engine reaches 15,000 horsepower. ”

"It's amazing!" Chen Geng gave an expression of amazement very cooperatively--of course, he was indeed amazed, Nima, after two lifetimes, finally saw the real NK-12 (for the products of the Kuznetsov Design Bureau, because of translation problems, some materials are translated into NK, and some are translated into HK, let's unify a little and use NK): "I heard that airplanes can be changed to gas turbines, right?" If this NK-12 is changed to a gas turbine and used on a ship, it will be very powerful, such a volume has 15,000 horsepower, and 10 units to form a unit to use it is 150,000 horsepower. ”

The corners of the mouth of the comrade of the Soviet "Ministry of Foreign Affairs" accompanying him twitched vigorously: You really think about building ships all the time.

The corners of Andrei Shamanov's mouth twitched twice: "Uh...... Our Kuznetsov Design Bureau has a marine gas turbine, I heard that you came here on our Soviet Tu-154 airliner? The engine here is the engine used in the Tu-154 airliner: the NK-8 turbofan engine......"

"Isn't that right?" Chen Geng laughed evilly in his heart, but there was a puzzled expression on his lips: "When we came, the crew introduced us and said that the Tu-154 was equipped with an engine that seemed to be the Soloviev Design Bureau, and this ...... What's going on? Am I mistaken? ”

The corners of Andrei Shamanov's mouth twitched twice!

Kuznetsov, Soloviev and Lotarev are the three most famous aero-engine designers in the Soviet Union, the pillars of Soviet aviation power, and also the three chief engineers of the Soviet Union's development of large-bypass turbofan engines, but there is also a problem here, just like the cross talk even said "those who talk about cross talk are looking forward to the death of their peers", this aero engine is not harmonious, Kuznetsov, Soloviev and Lotarev, the three chief aero engine design engineers, there is also dirtiness between them, and even the use of "dirty" It's not appropriate to describe it, and many times it's just a matter of stabbing each other twice.

What am I? For example, in the engine of the Tu-154 passenger plane, the Tu-154A is still the NK-8-2U of the Kuznetsov Design Bureau, but the Soloviev Design Bureau does not know how it is organized, and the engine supplier qualification of the Tu-154 passenger plane is snatched from the Kuznetsov Design Bureau, and it is here at the Tu-154M. The engine of the aircraft was changed from the NK-8 of the Kuznetsov Design Bureau to the D-30K of the Soloviev Design Bureau.

Now Chen Geng said that the Tu-154M they were riding was carrying Solovyev's D-30K instead of the Kuznetsov Design Bureau's NK-8, which was simply pouring salt into the wound of the Kuznetsov Design Bureau.

Although he was sprinkling salt on the wound, he still had to answer in the face of Chen Geng, who looked like a curious baby, and Andrei Shamanov pretended to be casual and said: "The Tu-154 can be equipped with two engines, one is the NK-8 of our Kuznetsov Design Bureau, and the other is the D-30K of the Soloviev Design Bureau that you said. ”

"I see?" Chen Geng couldn't help but laugh and pretended to suddenly realize: "It seems that the Tu-154 that our country bought is an optional D-30K." ”

Andrei Shamanov: "Hehe......"

"By the way, Mr. Andrew, which is better, D-30K or your NK-8?"

"Of course it's our NK-8." Andrei Shamanov's chest straightened, and he looked at Chen Geng proudly, "Do you still have any questions about this issue?" "Failed?!

"That's the case," Chen Geng frowned, and said to himself: "If I'm not mistaken, the maximum thrust of NK-8 is 93.2kN, and the maximum thrust of D-30KU is 104kN, D-30KU's economy, comfort and reliability are better, is the crew lying?" ”

“……”

Andrei Shamanov's face completely turned the color of pig liver, and Chen Geng clearly saw it in his eyes, "Will you chat?" You say, will you chat?! "Anger, how can there be a person like you? Obviously, you already know the technical gap between the two engines, and you still pretend that you don't know anything, is it fun to fool people?

It felt almost over, and Chen Geng also accepted it when he saw it, and said with a smile: "But it may be that I remember it wrong, huh...... Mr. Andrey, you invited me just to show me the product line of the Kuznetsov Design Bureau, right? ”

"Of course not," Andrei Shamanov, who had just almost been anxious with Chen Geng, quickly adjusted his mood, looked at Chen Geng and asked: "Mr. Chen, I heard that you are going to introduce the D-30KU engine on the picture-154M from the Soloviev Design Bureau?" ”

"To correct it, it's not the D-30ku on the Tu-154M, it's the D-30K series, and there is also the D-36 of the Progressive Machine Building Bureau," said this, Chen Geng stopped selling the guanzi and asked Andrei Shamanov: "Mr. Andrei, could it be that the Kuznetsov Design Bureau invited me to come, and it also has something to do with this?" ”

"That's right," Andrei Shamanov asked Chen Geng to sit down on a chair, and said bluntly to Chen Geng: "I want you to think about our Kuznetsov Design Bureau." ”

Pointing to the NK-25 engine mounted on the Tu-22M3 "Backfire" bomber in front of him, Chen Geng said: "The Kuznetsov Design Bureau is very powerful, but let's not talk about whether our request for cooperation can be approved by the Soviet government, even if it is approved by the Soviet government, your design bureau does not have a product that can meet our requirements, right?" ”

After a pause, Chen Geng explained: "Runhua Industry is very optimistic about the development of the world's aviation industry, we believe that the next 21st century will be the century of aviation, we have said that the aviation industry is listed as one of the pillar industries of Runhua Industry in the future, we hope to develop into an internationally renowned aero engine provider that can compete with IAE and CFM in the future, and become a force to be reckoned with in the international aviation field......

Runhua expects to have the ability to produce high-thrust turbofan engines of more than 100kN and turbofan engines with a large bypass ratio of 60 to 70kn at the same time, so we are ready to invest a huge amount of money to introduce the related technology and manufacturing equipment and manufacturing process of these two types of engines......"

Andrei Shamanov refused to believe a word about Chen Geng's words, and he didn't believe that the KGB comrade who claimed to be the Soviet Foreign Ministry, but it doesn't matter, it's one thing whether you believe it or not, the key is that I have a reason, and that's enough.

The Kremlin people and the KGB people firmly believe that behind the action of Runhua Industry to purchase D-30K and D-36 engine technology, there is definitely the intention of the Republic government, although for a time the Soviet Union still did not understand what the Chinese wanted to do, and the specific intentions of the Chinese were still being analyzed, but one thing is certain, that is, the Chinese will definitely not only use these two engines in the civilian field.

So the question is, whether to sell such technology to the Chinese?

The Kremlin is still having a fierce quarrel, and the old gods of the Soloviev Design Bureau and the Progressive Machine-Building Bureau, whose names were mentioned by Chen Geng, are waiting for the Kremlin's orders, and only the Kuznetsov Design Bureau is completely anxious after hearing the news!

Because the boss of the Kuznetsov Design Bureau: Mr. Kuznetsov had a bad relationship with Silaev, the deputy minister in charge of aircraft engines of the Ministry of Aviation Industry of the USSR, and the boss of the Soloviev Design Bureau: Soloviev was very close to Silaev, resulting in the selection of the power system of the Soviet large aircraft, the Kuznetsov Design Bureau, which was not weak in technology, repeatedly "fell out of favor" with the Soloviev Design Bureau, and the same was true in the research and development process of the large bypass ratio turbofan engine that represents the international development trendThe Soloviev Design Bureau was allowed to develop the D-90 (PS-90) turbofan engine with a large bypass ratio, and the Progressive Machine-Building Bureau led by Lotarev simply already had the D-36 and the D-18T developed from the D-36, but what about the Kuznetsov Design Bureau? Their NK-56 turbofan engines with large bypass ratios were ordered to be dismounted by Silaev!

Seeing that the life of the two old rivals is getting better day by day, but they are not getting better day by day, how can the Kuznetsov Design Bureau not be in a hurry? And the appearance of the Chinese made the Kuznetsov Design Bureau see it as a lifesaver to reverse the current situation! (To be continued.) )
