Although Chen Geng attaches great importance to this cooperation with the bank, this does not mean that Chen Geng will devote all his energy to it, and compared with this cooperation with the bank, Chen Geng seems to attach more importance to the Il-76-LL aero engine air test platform that arrived just a few days ago. Pen, fun, and www.biquge.info

Standing in front of the plane, Chen Geng looked at the behemoth in front of him, and after a while, he turned his head to the comrades of the Air Force and asked, "Li Gong, how is the state of this plane?" ”

"Good, very good," Speaking of this plane, the chief engineer Li from the ground service of the Air Force kept nodding his head and chattering excitedly at Chen Geng: "The Soviet Union has spent no less effort on this plane, although the plane is a little old, but the frequency of use is not high, the maintenance work is also in place, the performance of almost all parts is at the peak, I have never seen an old Maozi aircraft can maintain such a good state." ”

As the first and only aero-engine air test platform in China converted from a large four-engine jet transport plane, the Air Force and the AVIC attached more importance to the Il-76-LL than Chen Geng had imagined; before the plane arrived in Haizhou, the Air Force dispatched two capable maintenance teams from the ground crew who were already familiar with the Il-76 aircraft to rush to Runhua Industrial to assist Runhua Industrial in carrying out a comprehensive overhaul of the Il-76-LL.

"All in peak condition?" Chen Geng was a little surprised: "Lao Maozi is enough for the next book." ”

"Who's to say it isn't?" Chief Engineer Li smiled from ear to ear, he knew too well the importance of such an aircraft to the aviation industry of the Republic, especially the aero-engine industry: "The equipment inside is also very well maintained, and the specialists of the Kuznetsov Design Bureau are carrying out the final debugging, but we don't understand the ...... of those things."

Specialists from the Kuznetsov Design Bureau are debugging test equipment in the cabin? Chen Geng hurriedly went in, ready to take a look at the excitement.

Because it is on the ground, this Il-76-LL did not start the engine to consume the engine's precious service life, but relied on the ground power supply vehicle to provide power for the operation of the internal equipment, and when you walked into this Il-76-LL, it was a bit like an early warning aircraft in the air, and all kinds of testing equipment were full, and more than a dozen experts from the Kuznetsov Design Bureau working in Runhua Industry were carrying out various debugging and testing of the equipment.

Seeing Chen Geng and Old Man Xie coming in, Avdjevich, deputy chief engineer in charge of improving the NK-8 engine, immediately greeted him.

On the contrary, his face seemed to be more excited, and he took the initiative to introduce to Chen Geng and Xie Minsheng without waiting for Chen Geng to ask: "Chen, Xie, we have just completed the testing and debugging of the testing equipment, and all the systems are working well. ”

"All well?" Chen Geng was a little surprised, he thought that there should be more or less small problems, but now Avdeyevich actually told himself that there was not even a little problem with this plane and all the test equipment on the plane, and it was in good condition as if it had just left the factory and completed the final test.

Avdeyevich affirmed: "Let's put it this way, even if we let this big guy start working now, if our engine is assembled, there will be no problem using this aircraft as a temporary ground test center." ”

This answer was not only beyond Chen Geng's imagination, but also beyond Old Man Xie's thoughts, and Old Man Xie was quite surprised: "This thing can also be used as a ground test center?" ”

Avdeyevich explained to the old man: "In essence, this kind of aero engine air test platform is to integrate an aero engine testing center into an aircraft, which can not only test the actual working conditions of the engine in the air, but also do all the ground test work.

Of course, it's okay from a feasibility point of view, but from a cost-effective point of view, it's not cost-effective to do ground testing with an aerial test platform, and no one usually does that. ”

That's right!

Listening to Avdeyevich say this, Old Man Xie also reacted, this is like a target that can be solved with a single shell, you don't need to choose a ballistic missile whose price is not known how many times more expensive than an artillery shell to solve it, can a ballistic missile solve it? It's certainly fine, but it's a bit wasteful to use ballistic missiles to solve a target that can be solved with a single shell.

Chen Geng doesn't care about waste or not now, he cares about when the first batch of this improved, a total of five engines, will be produced and tested to begin.

To this question, Avdeyevich replied: "Three months, another three months will be about the same." ”

"How long is it going to take?" Chen Geng's brows furrowed when he heard this, and he was a little dissatisfied: "It won't take so long for the Kuznetsov Design Bureau to produce an engine, right?" ”

As an ultra-high-precision equipment, the production of aero engines is an extremely time-consuming thing, even for the United States, the Soviet Union and other aviation industry powers, the production of an engine also takes dozens of days or even months.

In order to improve the production speed and efficiency, the concept of "batch" was born: according to the actual needs, a few or dozens of engines are produced at a time, and then the next batch is put into production every once in a while according to the production process and speed, so that the result is to ensure that the engine is produced in a steady stream like assembly line products, but even so, such as Rolls-Royce, Pratt Whitney, General Dynamics and other world-class aero-engine giants, The total annual output of various types of aero engines is only a few hundred or thousand.

Although Runhua Industry has introduced a full set of production equipment from the Soviet Union and many skilled workers from the Kuznetsov Design Bureau, considering that Runhua Industry has never had the technology and experience to produce turbofan engines, out of prudence, most of the production work of the five engines used for testing was handed over to the Kuznetsov Design Bureau, and Runhua Industry is only responsible for the production of some pipelines, shells and other equipment with low technical content.

However, Chen Geng did not expect that the Kuznetsov Design Bureau, which began to prepare materials at the same time during the design period and began to deploy production as soon as the design work was completed, would take more than four months to complete the production of this batch of five engines, and you must know that before the collapse of the Soviet Union, the Kuznetsov Design Bureau produced a batch of NK-8 series engines for about 50 days.

"Sir, we can't help it, you know, the situation in Russia is a mess right now," Avdeyevich lowered his head, and was also helpless about this result: "In fact, it will be smooth to successfully complete the production and assembly of the engine in three months, and I am a little worried......"

Hearing Avdeyevich's words, Chen Geng and Old Man Xie subconsciously frowned: This is indeed a problem, the collapse of the Soviet Union has too much impact on the normal production of the Kuznetsov Design Bureau.

Old Man Xie tilted his head slightly, and Chen Geng gestured to say.

When Old Man Xie came to the side, Chen Geng said in a low voice: "Three months is not a big problem, but what I'm worried about is that if the impact of the collapse of the Soviet Union is greater than we imagined, what if it is not completed after three months?" What should we do if this delay is delayed again and again, for half a year, or for more than half a year? ”

"I'm also worried about this problem," Old Man Xie also frowned: "Not only this, according to our early plan, in the future, we will hand over the production of engine parts to the Kuznetsov Design Bureau, if they keep dropping the chain like this, then the problem will be serious." ”

Chen Geng didn't speak, but his expression was as dignified as Old Man Xie's.

Indeed, there is no way to accurately assess how much impact the collapse of the Soviet Union had on the normal production and life of the Kuznetsov Design Bureau, but there is no doubt that this impact can not be overestimated in depth, Chen Geng is very clear that from the collapse of the Soviet Union in 1991 to the next 10 years, Lao Maozi's life is simply not as good as the gray life of the tsarist era, and the whole Russia can be said to have almost collapsed.

In this case, expecting the Kuznetsov Design Bureau to be able to complete the cooperation between the two sides on time with quality and quantity, Chen Geng felt that this optimism was a bit too much, and what was even worse was that if someone secretly made a mistake and made some problems at a key node of Runhua Industry, Runhua Industrial's aviation business, which had just started with difficulty, would be in big trouble.

Old Man Xie was most familiar with Chen Geng, and when he saw Chen Geng's flickering eyes, he guessed that Chen Geng was beginning to brew his own calculations: "What solution have you thought of?" ”

"The aircraft engine production equipment we imported from the Soviet Union will also be used by these technicians of the Kuznetsov Design Bureau, right?" Chen Geng pondered for a moment, not very sure.

"I will use it," compared with Chen Geng, who is good at strategy, Mr. Xie, who is in charge of the specific affairs of the group, is more aware of these situations: "Have you forgotten, these equipment are still taught by the comrades of the Kuznetsov Design Bureau how to use them and help us get familiar with them." ”

"That's it," Chen Geng nodded, and asked again: "Then have we counted how many of the skilled workers in the Kuznetsov Design Bureau of Runhua Industry are directly in the front-line production positions?" What percentage of these front-line production positions can account for in all production processes of NK-8? But since they taught us how to use every piece of equipment, it should be that there are people from the Kuznetsov Design Bureau in all positions, right? ”

Old Man Xie's eyes lit up: "You mean ......"
