Chapter 910 Huateng Group is too powerful
Not only expert Liu, but also the entire 57XX factory team did not expect that the Russian aunt who eats like a man and has the same body shape as a polar bear is an engineer of high-pressure turbine blades for aero-engines. Some people even suspect that Did Zhang Qihang make a mistake? He couldn't help but ask Zhang Qihang: "Mr. Zhang, you said she is responsible for the production of high-pressure turbine blades for aero-engines?"

People who produce high-pressure turbine blades can only be called technicians, not engineers.

Of course Zhang Qihang understands the difference between the two, and shook his head: "No, Ms. Natasha is the technician responsible for developing high-pressure turbine blades. In fact, not only high-pressure turbine blades, but also Ms. The R&D and manufacturing of turbine disks are quite powerful,"

Speaking of this, Zhang Qihang pondered for a while, and revealed a little information: "We have negotiated with the relevant leaders of the Air Force before. When we intend to engage in the overhaul of the D-30K series engines, we have expressed to the relevant leaders of the Air Force that we intend to On the basis of the D-30KP-2 engine, this engine is further optimized to increase power and reduce fuel consumption, Professor Liu, I wonder if you have heard of this matter?"

Expert Liu frowned and thought for a while, and finally nodded uncertainly: "It seems that there is such a thing..."

Speaking of this, he looked at Zhang Qihang, implying: Don't tell me that you really plan to do this.

Facing Expert Liu's eyes, Zhang Qihang nodded affirmatively: "Since the last time we discussed with the leadership of the Air Force, we have entrusted the comrades of the Air Force to purchase two brand new D-30KP-2 engines from the old lady for use in the air force. R&D and testing.

After the arrival of the two D-30KP-2 engines, Mr. Sergei Izotov took our aero engine team... including Ms. Natasha... to start the optimization of the D-30KP-2 engines , because the whole team is very familiar with this engine, so the progress of the whole project is very fast, and now the whole design work has been basically completed, the next thing to do is to use the computer to simulate the full working conditions of this scheme, as long as the scheme is passed After computer simulation test, the prototype can be manufactured. "

Expert Liu opened his mouth in surprise: "This...how is this possible?"

It's no wonder that Expert Liu was so surprised. It really sounds outrageous, because everyone who knows aero engines knows how difficult this thing is, otherwise it wouldn't be called "the crown jewel of modern industry." Pearl of the

As one of the technical leaders of the 57XX factory, Expert Liu is also one of the top experts in the field of aero-engines. He has a light understanding of the technology and R&D level of domestic aero-engines. It will take at least 10 years for the level of engine manufacturing and R&D capabilities to reach the same level as Liming Plant, but the D-30KP-2 can be imitated, but what about the current situation?It has been less than a year since Huateng Industrial Group applied for the establishment of the D-30KP-2 engine overhaul factory, and Huateng Industrial Group claimed that it has completed the optimization work of D-30KP-2?
Why does this sound so outrageous?
There is no such thing as nonsense!
A few years ago, this kind of behavior was called "satellite release"!
But having said that, considering that the person in charge of this project is the second chief designer of the Klimov Design Bureau of the former Soviet Union, Expert Liu dare not believe it completely.

"This is actually a coincidence," Zhang Qihang said with a smile to the shocked expert Liu, "You may not be very clear that in the former Soviet Union, the Soloviev Design Bureau that produced the D-30KP-2 engine cooperated with the Kerry The relations of the Mov Design Bureau are good, and Mr. Sergei Izotov is very good with the chief designer of the Soloviev Design Bureau: Mr. Pavel Pressure Sandrovich Soloviev friend.

When the Soloviev Design Bureau evolved the D-30 series engine to the D-30K series, the two design bureaus also carried out in-depth cooperation, so Mr. Sergey Izotov’s understanding of the D-30 series engine was actually It is very familiar, and it is not impossible to say that the D-30K series engine was jointly developed by Mr. Pavel Sandrovich Soloviev and Mr. Sergey Izotov. "

Sergei Izotov had a good relationship with the founder of the Soloviev Design Bureau Mr. Pavel Stressandrovich Soloviev?

It can even be said that the D-30K series engine was jointly designed and developed by Mr. Pavel Sandrovich Solovyev and Sergey Izotov?

And now Mr. Sergei Izotov is in charge of this project?

This series of shocks made Expert Liu's mind go blank, and he was speechless with his mouth wide open.

But he knew in his heart that if this was the case, there was a high probability that Huateng Industrial Group... Zhang Qihang would not be able to joke about such things...

So, although this story sounds outrageous, it is very likely to be true?
Realizing this, Expert Liu suddenly became excited, but said nervously: "Mr. Zhang, you can't joke about this kind of thing."

"Of course I can't make a joke about this kind of thing," Zhang Qihang nodded affirmatively, "Well... I wonder if you are interested in improving the performance of the improved D-30KP-2 engine?"

Expert Liu nodded hurriedly: "Of course, has the performance improved a lot?"

"A lot," Zhang Qihang responded with a nod, "According to this improvement plan, the newly designed D-30KP-3... because of too many changes, we all feel that this engine can no longer be called D-30KP-2, but should be It is called D-30KP-3... the maximum ground thrust is close to 140 kN, the bypass ratio has been increased from 2.24 to 3.62, and the take-off fuel consumption has been reduced from 0.51kg/(daN*h to 0.404kg/(daN*h, Cruising fuel consumption has been reduced from the previous 0.71kg/(daN*h to 0.643kg/(daN*h, and the noise level, overhaul interval and overall lifespan have also improved a lot..."

"..."

Before Zhang Qihang finished speaking, Expert Liu's eyes widened, and he said in a trembling voice, "Mr. Zhang, you can't joke about this kind of thing."

Zhang Qihang nodded affirmatively: "Of course I can't joke about this kind of thing."

"Okay," Expert Liu scratched his head and said, "But Mr. Zhang, I still can't understand, how did you do it?"

It’s no wonder that Expert Liu thinks this way, because it sounds really impossible. You know, how difficult it is to optimize an aero engine. Take the type with the largest installed capacity in our country Aviation engine: Turbojet-7 as an example, although continuous improvements have been made over the years, each improvement can only be described as "small steps and quick runs". How could there be such a substantial performance improvement?

And is it an almost all-round and all-dimensional improvement in thrust, fuel consumption level, life span and even noise level?
In Liu's opinion, if aero-engines are so easy to develop, then what's the point of the country supporting us?We people simply jump into the river collectively.

Zhang Qihang did not expect Expert Liu to admit his mistake so quickly. He was a little surprised, but more admired. He nodded and said: "I understand your thoughts very well, this sounds really incredible, because it is really Difficult, but then again, if you stand in the position of Mr. Sergei Izotov, do you still think that the improvement of this engine is difficult? It is like standing in the perspective of a university professor, he will think that high school mathematics is difficult Is it? Isn’t that something you can solve with your hands?”

"..."

Expert Liu was dumbfounded when he heard this, and was speechless for a long time: Yes, for university mathematics professors, isn't it enough to have hands in high school?

Looking at the dumbfounded Expert Liu, Zhang Qihang couldn't help laughing.

Speaking of which, even Zhang Qihang did not expect that his family would evolve to the "D-30KP-3" stage so quickly. Originally, he also thought that Huateng Industrial Group should first accumulate some experience through the overhaul of D-30KP-2. Then began to try to imitate D-30KP-2, and waited for 10 years to fully master the production technology of D-30KP-2 before trying to enter the "D-30KP-3" stage, but the reality is so amazing After the "D-30KP-2 overhaul" project was launched, Sergei Izotov heard Zhang Qihang talk about his idea of ​​"from D-30KP-2 to D-30KP-3", and directly gave it a big hand. He waved and said: "It's so troublesome? Why bother with that? I'm familiar with D-30KP-2. Leave it to me. Let's do the D-30KP-3 you mentioned directly."

Then, Zhang Qihang was surprised to see that Sergei Izotov came up with a preliminary plan in just one month, and officially launched "D-30KP-3" after getting the approval of the group board of directors It took half a year to complete all the design work, and the whole process went smoothly.

Surprised, huh?
Do you think it's like a bloody urban novel?

但实际上原本历史时空当中D-30KP-3的研制工作，确实就是这么轻松：2003年，生产D-30KP-2的大毛“留里卡-土星”科研生产联合体提出了改进型D-30KP-3“纤夫”发动机的研发计划。

Because it is the improvement of the model rather than the development of a new model, the whole project is going very smoothly, and the biggest improvement of the whole project is to change the original bulky three-stage fan of the original D-30KP-2 into a new design The unique single-stage fan increases the engine bypass ratio from about 2.24 to 3.62.

The entire improvement project, in addition to increasing the thrust of the engine from 30 kN of D-2KP-125 to close to 140 kN, the noise and fuel consumption rate were significantly reduced, and the overhaul interval was further extended, compared with the original D-30KP -2, the overhaul interval of the engine is extended by 1.2 times, but its price is only about 30% more expensive than D-2KP-20, especially the noise level during flight has reached the standard stipulated by the International Civil Aviation Organization. At the same time, the engine consumption Oil volume can also be reduced by 18%.

而留里卡-土星科研生产联合体对D-30KP-3的改进过程中最牛的一点在于，该型发动机使用了D-30KP-2的75%的零件，这也就意味着老款的D-30KP-2完全通过改装的方式将自身升级为D-30KP-3，事实上也确实是可以这么做，改装成本为84万米元（2005年）。

The entire "Tracker" project started in 2003, and the ground test had been completed by the spring of 2005. One can imagine how long the entire design phase took.

The Huateng Industrial Group has Sergei Izotov and Igor Yaroslavsky, the best aero-engine talents in the former Soviet Union, and Zhang Qihang has been continuously improving from various aviation engines in Da Mao's family over the years. The equipment drawn by the engine design and R&D unit, as well as the personnel engaged in front-line production and technology R&D, took only half a year to complete the improvement and design of the D-30KP-2 engine, which is actually very slow—don’t forget, 2003 How serious was the brain drain of the Rurika-Saturn scientific research and production complex in 30, but even so, it only took less than half a year for them to complete the improvement from D-2KP-30 to D-3KP-[-] Work.

Of course, if you ask why our country insisted on purchasing D-30KP-2 instead of D-30KP-3 after that, you can only blame Mao Zixin for being too dark: the price of D-30KP-2 is only more than 120 million US dollars , but the quotation of D-30KP-3 exceeded 200 million US dollars. Based on the financial situation of our country at that time, the difference between these hundreds of engines was a lot of money, what can a rabbit do?
Of course, Expert Liu didn’t know about this, but it didn’t matter at all if he didn’t know about it. After the initial shock, Expert Liu suddenly remembered what Zhang Qihang had just said that Huateng Industrial Group had already begun to prepare for the trial production of this product, which they called The D-30KP-3 improved prototype of D-30KP-2, he suddenly became excited, and suppressed the excitement in his heart and said in a trembling voice: "Mr. Zhang, you can't joke about this kind of thing."

"Of course we can't joke about this kind of thing," Zhang Qihang nodded affirmatively: "There should be experts in the field of turbofan engines in our team? If you want to know if there is any problem with our plan, we can come up with the plan Evaluate everyone."

Hearing Zhang Qihang's words, how can Expert Liu still think about eating?He took a deep breath, stared at Zhang Qihang, and said solemnly in a low voice: "Comrade Zhang Qihang, are you serious? Are you really willing to take this plan out for evaluation?"

Zhang Qihang looked at Expert Liu, and said equally seriously: "Leader, I am very clear about the purpose of this engine. Before our country has no suitable installation targets, after this engine is produced, it will either be used in the form of a modified kit. The engine of the Il-76 transport aircraft equipped by the state is modified, or..."

Speaking of this, Zhang Qihang couldn't help hesitating for a moment, wondering whether he should say the next thing or not.

Expert Liu, on the other hand, quickly asked, "Either what?"

Zhang Qihang hesitated for a moment, then said: "Either, replace H30's turbojet-3 from last year with D-6KP-8."

The current H6K project is still under discussion, and the number H6K does not exist at all. In this case, I can only say that I use this engine to refer to the turbojet-8.

What Zhang Qihang said made Expert Liu's eyes suddenly brighten: use this so-called "D-30KP-3" produced by Huateng Group to replace the WP-8?

The 57XX factory is the largest aero-engine overhaul shop in the Air Force, and there are not many turbojet-8s that have been repaired. Expert Liu, as an expert of the 57XX factory, is especially familiar with the H6 aircraft and the turbojet-8 engines it carries. Familiar ones cannot be more familiar, therefore, upon hearing this, he subconsciously compared the WP-8 with the D-30KP-2 he is more familiar with to measure whether the D-30KP-2 has the capability to replace the WP-8. [-] possibilities:
The first is the turbojet-8, with a maximum weight of 3100 kg, a maximum diameter of 1400 mm, and a maximum thrust of 9500 kg;

Then there is the D-30KP-2 that I am familiar with, with a maximum weight of 2668 kg, a maximum diameter of 1560 mm, and a maximum thrust of 12500 kg...

Hiss, almost!

The D-30KP-2 is only slightly thicker in diameter than the WS-8, but it is lighter in weight and has greater thrust. What is even more rare is that the two engines are a turbojet and a turbofan, and there is no comparison in terms of fuel consumption. sex;
Although the diameter of the D-30KP-2 is slightly thicker, but Xifei has developed so many improvements on the basis of the original version, I believe that the engine compartment should be fine-tuned to adapt to the new engine, there is no problem at all.

The next question is, since the D-30KP-2 can be installed in the engine compartment, will the so-called "D-30KP-3" made by Huateng Industrial Group be a big problem?Anyway, it is necessary to adjust and modify the engine compartment...

Thinking of this, Expert Liu couldn't calm down at all. He first told Zhang Qihang in a low voice, "Mr. Zhang, please wait for me first", and then hurried to the visiting team of 57XX factory. In front of the unobtrusive person, he whispered something to him.

After a while, this unremarkable man couldn't calm down anymore. He glanced at Zhang Qihang, and then said something to Expert Liu in a low voice. Expert Liu nodded repeatedly, and desperately lowered his voice to talk to him. Then, soon, this man's expression became very serious, he pursed his lips, and quickly came to Zhang Qihang, first handed Zhang Qihang a certificate: "Mr. Zhang, this is my certificate, you Take a look first."

Zhang Qihang was not polite either, he opened the ID and glanced at it, then looked up at Expert Liu in surprise.

Expert Liu didn't speak, but nodded affirmatively.

Zhang Qihang nodded and returned the certificate to the old man: "I'm fine, Comrade Sun, what do you want to say to me?"

Comrade Sun said in a deep voice: "Mr. Zhang, Expert Liu has roughly reported some situations to me. I think these situations are very important, so I need to contact my colleagues next, and my colleagues and I will discuss some matters individually. I would like to check and confirm with you, the entire confirmation and verification process will be recorded and recorded, and we need you to find a quieter room, do you have any questions?"

Zhang Qihang couldn't help but frowned: "Is this an interrogation?"

"Of course it's not an interrogation," Comrade Sun explained: "But Mr. Zhang, you should understand that if what you said is true, this matter will have a great impact on our national defense security, so..."

"I understand," Zhang Qihang nodded and said, "I can cooperate with your work, there is no problem with this, but I want to report this situation to the leader of our provincial state-owned assets office... Don't worry, I won't say what I shouldn't say , You can also be by the side during the entire call, but the entire verification process must be attended by relevant personnel from our province."

Zhang Qihang's identity is so special, Comrade Sun hesitated for a moment, and finally nodded: "Yes, but I must be present when you call, and from now on, I will follow you every step of the way, including when you go to the toilet .”
