Chen Geng didn't know the dirt between the Kuznetsov Design Bureau, the Soloviev Design Bureau, and the Progress Machine-Building Bureau, the three major aircraft engine development institutions in the Soviet Union, but it didn't matter if he didn't know this, he only needed to know one thing: after he had just conveyed his ideas to the Kremlin through the Likhachev Automobile Factory, when the Soloviev Design Bureau and the Progress Machine-Building Bureau had not moved, the Kuznetsov Design Bureau, which had not been considered by himself, actually jumped out first, what does this mean, Isn't it like lice on the top of a bald man's head - obviously?

"Can I assume that if the Kremlin approves our request for the introduction of technology, the Kuznetsov Design Bureau is ready to provide us with the corresponding technology and equipment, processes?" Chen Geng asked Andrei Shamanov tactfully and directly at all. Pen × fun × Pavilion www. ｂｉｑｕｇｅ。 ｉｎｆｏ

Although Chen Geng's words were directly unbearable, after some hesitation, Andrei Shamanov still nodded: "Of course, if the Kremlin approves it, there is no doubt about it." ”

"But what I know is that the NK-8 engine lags behind the D-30ku of the Soloviev Design Bureau in almost all key indicators such as maximum thrust, comfort, safety, and economy," Chen Geng's words were quite direct, staring at Andrei Shamanov...... There are some regrets. ”

"No, no, Mr. Chen, I think you seem to have misunderstood," Andrei Shamanov was stunned for a moment, and hurriedly explained to Chen Geng: "NK-8 is a series of engines, and the Kuznetsov Design Bureau has set different thrust output levels according to different needs, and the Tu-154 is equipped with the basic models of NK-8-2 and NK-8-2U, but there are also NK-8-3 series and NK-8-4 series on the NK-8-2 series...... Until the NK-8-6 series, the NK-8-6 series was carried on our latest Soviet Union's Il-86 large wide-body passenger aircraft, and the maximum thrust could reach 127.5kN.

By the way, in the early 70s, your country introduced a large civil airliner that can fly across continents, the Il-62M, which is equipped with the NK-8-6 of the NK-8 series of our Kuznetsov Design Bureau, and the early model of the Il-62 uses NK-8-4, and the maximum thrust of NK-8-4 is also 103kN, which is equivalent to the D-30KU on the Tu-154M. ”

Of course, like the NK-8 series of the Kuznetsov Design Bureau, the D-30K of the Soloviev Design Bureau is also a complete engine series, and even the D-30K used by the Tu-154M will also be different in terms of maximum thrust of the engine because of different batches, self-use and export, so there is no need to tell Chen Geng.

NK-8 is a series?

Listening to Andrei Shamanov say this, Chen Geng is confused at the moment, what else do you say?

Suddenly, one thing came to mind: the first mass-produced version of the Tu-154 passenger aircraft was equipped with the NK-8-2 engine of the Kuznetsov Design Bureau, and the later improved Tu-154A was equipped with the same improved engine: NK-8-2U;

He also thought of the "doomsday aircraft" Il-80 developed during the former Soviet Union that had undergone limited declassification after 2000, and the Il-80 was an air command aircraft modified on the basis of the Il-86 wide-body civil aviation aircraft and modified for state-level command during the nuclear war. You will be amazed to find that the engine data of the Il-62 has changed to NK-8 again!

Yes, both aircraft are equipped with the same engine, but one is NK-86 and the other NK-8, the early model is NK-8-4, and the later Il-62M is NK-8-6!

From this, it can be deduced that the Il-86 and the doomsday aircraft Il-80 modified from the Il-86 are not carrying NK-86, but NK-8-6.

O Nima!

Thinking of this, Chen Geng wanted to scold his mother: Where did you translators go in the rigorous spirit of research? And those of you who quote later, don't you know how to be more careful? Do you know how many military fans and military enthusiasts have been miserable because of your lack of rigor?

As for whether the Soviet Union told the truth when it was carrying out propaganda, or whether it set off a smokescreen to confuse the enemy, Chen Geng didn't care.

What he is concerned about now is: "You mean, if the Kremlin agrees, the Kuznetsov Design Bureau will transfer to us the production technology, production processes, well, and production equipment of the NK-8 series?" ”

"If the Supreme Soviet agrees, of course." Andrei Shamanov nodded and replied in the affirmative.

Chen Geng's eyes were shining: "Just like when China was just founded, the Soviet Union supported our industrial construction, and taught us how to do it hand in hand?" ”

Andrei Shamanov hesitated for a moment, quickly exchanged glances with the comrade of the "Soviet Foreign Ministry", and then nodded: "If you make such a request to the Supreme Soviet, and the Supreme Soviet agrees, the Kuznetsov Design Bureau will have no opinion, and we will be happy to carry out the order of the Supreme Soviet." ”

That's great!

If it weren't for the fear of being told by the woolly bears in front of him how excited he was, Chen Geng would have been eager to jump: like the 156 projects aided by the Soviet Union in China, Runhua Industrial Co., Ltd. produced NK-8 series engines...... Nima, it feels like a pie in the sky......

Although Andrei Shamanov has repeatedly stated that unless the Supreme Soviet of the Soviet Union orders them to do so, Chen Geng is not a fool, how can he not hear another meaning of Andrei Shamanov's words: If you choose our Kuznetsov Design Bureau, we will take the initiative to help you work with the Supreme Soviet and the Kremlin.

Although the Soviet Union attaches great importance to the establishment of diplomatic relations with the Republic, this establishment of diplomatic relations is more about helping the Soviet Union share the pressure of the United States politically and diplomatically. To be honest, the Kremlin's masters may now think that this is the meaning of the republic, but if they know that this is just Runhua Industrial's personal meaning, it is uncertain whether they will turn around and forget about it.

But if at this time there is the Kuznetsov Design Bureau constantly beating drums on the side, it will be different, I dare not say that this will definitely be done, but it will definitely greatly increase the success rate.

On the other hand, from Chen Geng's own heart, the reason why he did not consider the Kuznetsov Design Bureau before was because he felt that the Kuznetsov Design Bureau was inferior to the Soloviev Design Bureau, and the technical indicators of D-30K were better than Nk-8, but after figuring out what was going on, Chen Geng's heart also changed a lot: D-30K and NK-8 are both turbofan engines with small and medium-sized duct ratios, since the Il-62/62M, Il-76, Il-86, and even Tu-62M 154 So many planes can be exchanged with the NK-8 series and the D-30K series engines, so is it difficult for the future H-6K bombers of the Republic to change from the D-30KP-2 to the NK-8 series? There may be some technical obstacles, but it's less difficult than changing from a turbojet-8 to a d-30kp-2, right?

Compared with the Soloviev Design Bureau and the Progress Machine-Building Bureau, which he had previously admired, the Kuznetsov Design Bureau is no different from a nanny.

Holding back the excitement in his heart, Chen Geng frowned and said: "That being said, I am also very happy to be able to cooperate with the Kuznetsov Design Bureau, but the Kuznetsov Design Bureau does not have a turbofan engine with a large bypass ratio, right?" ”

Well?

Hearing Chen Geng's words, Andrei Shamanov was stunned for a moment, and his first reaction was: We are only going to cooperate with you NK-8, we are not ready to cooperate with you with the big duct than the turbofan.

But in the next 0.1 seconds, Andrei Shamanov suddenly reacted: Nima! If, after winning the NK-8, it can still get the turbofan project with a large bypass ratio, wouldn't the Kuznetsov Design Bureau make a lot of money?!

Of course, the Kuznetsov Design Bureau has no way to compare it with the Soloviev Design Bureau and the Progress Machine-Building Bureau; the D-36 large-bypass turbofan engine of the Progressive Machine-Building Bureau has been installed on the Yak-42 for several years, and the D-18T high-thrust and large-bypass turbofan developed from the D-36 has been installed on the An-124, and even the An-225 transport plane, which is specially developed for the Buran space shuttle, carrying six D-18T transport planes, will make its first flight this month.

The D-90 (PS-90A) large-bypass turbofan of the Soloviev Design Bureau has also begun flight tests, and if all goes well, it is expected to pass the state test run by 1991 and obtain an airworthiness license in the first half of 1992.

What does the Kuznetsov Design Bureau have? Kuznetsov has only one project, the NK-56 and NK-64, two high-thrust turbofan engines with a large bypass ratio, which were ordered to be stopped by Deputy Minister Silaev, and the project has been stopped, and all the data has been mothballed......

Well?! (To be continued.) )
