In addition to being able to start the layout as soon as possible after the collapse of the Soviet Union, Chen Geng also focused on the performance of the contracts signed with the Soviet Union before, such as the first batch of delivered TU-154M civil airliners...... Well, the NK-8-4 turbofan engine on board. Pen × fun × Pavilion www. ｂｉｑｕｇｅ。 ｉｎｆｏ

Andrei Shamanov volunteered to act as Chen Geng's tour guide and enthusiastically introduced the first batch of 8 NK-8-4 engines to Chen Geng: "Chen, this is the first batch of 8 NK-8-4 engines we produced, 6 of which are installed on the TU-154M you ordered according to your requirements, and the remaining 2 are directly sent to your maintenance center as spare engines......

Chen Geng was a little absent-minded, he couldn't understand the quality of this thing, his eyes were aimlessly looking in the warehouse, and his eyes suddenly fell on several extremely huge engines imported from the warehouse, those engines seemed to be in the final debugging stage, the size was obviously larger than NK-8-4, Chen Geng's visual inspection of the length of the engine had to be at least 6 meters, placed on a special trolley, it looked taller than himself, and the tail was obviously equipped with afterburner. Seeing this engine, Chen Geng's heart moved, and he asked, "Andre, what kind of aircraft engines are these?" ”

"What's that?" Andrei Shamanov hesitated, lowered his voice and said: "That's NK-32-1, it's the engine of the TU-160 bomber. ”

Sure enough, it's NK-32-1!

Looking at this huge engine, Chen Geng's saliva is about to stay: the military afterburner engine with the largest thrust really lives up to its name, and it looks respectful - I really want to pack a few to resist!

Thinking that this was the source of power for the elegant "White Swan", Chen Geng couldn't help but ask Andrei Shamanov: "Andrei, can I go over and have a look?" ”

"This ......" Andrei Shamanov hesitated.

"Are you afraid I'll steal these engines for you?" Looking at Andrei Shamanov, who was hesitant, Chen Geng pursed his lips and said, "What do you think I can do with such a big thing?" ”

That's right!

Hearing Chen Geng say this, Andrei Shamanov also reacted, the weight of a NK-32-1 is 3.4 tons, such a big guy, what can Chen Geng do with it? Destruction? That's even more of a joke, I don't understand aero engines, even if this thing is put in front of you, you don't know how to toss, Chen Geng is nothing more than a look in the past.

After figuring it out, Andrei Shamanov finally nodded, but still cautiously said to Chen Geng: "Okay, but, Chen, you can only watch, not move." ”

"Of course," Chen Geng nodded happily: "Don't worry, we are friends, I won't make trouble for you." ”

Andrei Shamanov breathed a sigh of relief, to tell the truth, he was really worried that Chen Geng would make trouble for him.

Looking at the engine in front of him, in terms of diameter, NK-32-1 and NK-8-4 are about the same, NK-8-4 diameter is 1442mm, NK-32-1 diameter is 1460mm, the biggest difference is the length of the fuselage, NK-8-4 is 5100mm, NK-32-1 diameter is 6000mm, put the two engines together and compare, it feels like ordinary people standing next to Da Yao.

If this engine could be mounted on the H-6...... Well, although the NK-32-1 is indeed a good thing, the H-6 really can't use such a high-end atmosphere and high-grade thing, the reason is very simple, the NK-32-1 engine is with afterburner, simply put, more consideration is given to the use of supersonic conditions in the design, but the H-6 did not consider supersonic speed at all when designing, and the NK-32-1 is installed on the H-6, and the ability of this engine cannot be brought into full play by installing the NK-32-1 on the H-6.

Chen Geng was thinking vigorously in his heart: Good things, can you find a way to get them? -- Our old boss Chen's old problem has started to attack again.

Looking at Chen Geng's face constantly changing, Andrei Shamanov didn't dare to take a breath, he was really afraid that Chen Geng would suddenly come up with an idea that he shouldn't have, it doesn't matter if he came up with an idea that shouldn't be, but what should he do when the time comes?

Under Andrei Shamanov's nervous gaze, Chen Geng let out a sigh of relief, looked at the engine in front of him and said to him: "Andrey, how different is this engine from the NK-8?" ”

Chen Geng didn't ask too carefully, but Andrei Shamanov understood, shook his head and said: "It's very large, not to mention the control system, but from the most basic structure, NK-8 is a single-rotor structure, NK-32-1 is the most efficient three-rotor engine, and it is also the only three-rotor afterburner engine specially designed for military use in the Soviet Union......" Speaking of this, Andrei Shamanov glanced at Chen Geng cautiously and said in a low voice: "Chen, I understand what you mean, but with all due respect, It was not possible for the USSR to transfer the technology of such engines to you. ”

"I know," Chen Geng nodded, how could he not know that it was absolutely impossible for the Soviet Union to let this absolute "important weapon of the country" outflow? Sighing, Chen Geng said: "Andrey, the design work of our NK-8 modification must be accelerated, and the cruising fuel consumption rate of 0.79 is too high, not to mention compared with the West, even if it is compared with your old rival Soloviev Design Bureau, there is no advantage." ”

Andrei Shamanov was a little ashamed.

It is also said that the cruising fuel consumption rate of the NK-8 engine of 0.79 is close to that of a turbojet engine, and I dare not say that it is the highest fuel consumption rate among turbofan engines, but it can definitely rank among the top three. Ying said: "Chen, don't worry, we are already in the process of debating the plan for increasing the bypass ratio to reduce fuel consumption, and our preliminary plan is to expand the NK-8 bypass ratio to 3, and it is expected that we will be able to come up with a preliminary plan by March next year -- the Kuznetsov Design Bureau has been engaged in NK-8 for more than 20 years, and this is not a problem." ”

Chen Geng immediately asked: "If the bypass ratio is expanded to 3, what level can the take-off fuel consumption rate and cruise fuel consumption rate reach?" ”

Andrey Shamanov: "Now there are only preliminary results, according to our preliminary calculations, if the bypass ratio can be expanded to 3, the take-off fuel consumption can be reduced to 0.43 to 0.45, and the cruise fuel consumption can be reduced to less than 0.65. ”

In the take-off state, the air density on the ground is large, the relative take-off fuel consumption rate is low, and the air density is low when cruising at high altitude, the cruise fuel consumption rate is relatively high, if the take-off fuel consumption rate can really be reduced to 0.43 to 0.45, the cruise fuel consumption rate is reduced to 0.65, and at the same time, the stability and reliability of the engine can be guaranteed, the performance of this engine is really bull X. Chen Geng thought for a while and said, "March next year, right?" No problem, I'm waiting for your good news. ”

After a pause, Chen Geng lowered his voice slightly and said, "Andre, you know, I never treat my friends badly. ”

"I understand!" Without waiting for Chen Geng to finish speaking, Andrei Shamanov nodded again and again: "Chen, don't worry, I know what to do!" ”

After many successive cooperations, Andrei Shamanov no longer has any doubts about Chen Geng's credit, he said that he will not treat himself badly, then he will definitely not treat himself badly, well, it seems that it is necessary to urge everyone to hurry up and work, seeing that the economic situation in the Soviet Union is getting worse and worse, there is nothing more important than making more money.

――――――――――――――――

I am going to return to China, but it is a pity that the first two Runhua Industrial customized TU-154M passenger planes equipped with NK-8-4 engines cannot go back with Chen Geng, the reason is that although the engine and the aircraft have been produced, because the previous version of the TU-154M is equipped with D-30KU engines, after replacing NK-8-4, the whole machine needs to be comprehensively debugged and tested, this process takes about 3 months, and it is absolutely indispensable, no way, Chen Geng can only wait patiently.

It's just that Chen Geng never expected that at this time, he would encounter a trouble......

"You're going to China with me? No way! ”

When Anna found Chen Geng and said that she wanted to go to China with him, Chen Geng almost went crazy: there was no way to do it in the Soviet Union, so it was enough, but after returning to China, do you want a Soviet agent to follow her? !

"I know what you're worried about, isn't that my identity, it's okay, I can go with you in a different identity." Anna was equally resolute, and she emphatically said, "That's what Director August meant." ”

"To hell with Auguste, then!" Chen Geng said without hesitation.

Not to mention August, even if it's August, although Chen Geng doesn't know what the Soviets have in mind, but let a KGB agent follow him to China with such a swagger?

What did the Soviets think?

"I tell you, don't say that August is only the head of the Samara regional branch of the KGB, even if he is the head of the entire KGB, don't expect me to agree to his request - it's a big deal, everyone will break up, and I'm sure there must be a lot of people willing to take over the current business from him."

Anna snorted, but she had to admit that what Chen Geng said made sense, if Chen Geng really didn't plan to give face to Director August, the director really couldn't do anything about this guy, but just give up? Anna was a little unwilling.

Chen Geng didn't care whether the Soviets were willing or not, and said angrily to Lin Shuyao, who was watching the excitement on the side: "What are you doing in a daze?" Let's go, let's go home! ”
