"Congratulations, you guessed it right," Chen Geng nodded to Mao Donghai with a mixture of shock, surprise, and disbelief, "The design of the first improved version of the NK-8, that is, the civilian version, has been completed......

Without waiting for Chen Geng to finish speaking, Mao Donghai had already taken Chen Geng's hand and asked eagerly, "When is it?" How did I not know? ”

After speaking, without waiting for Chen Geng to answer, Mao Donghai said to himself with a happy face: "With Lao Maozi's attainments in this engine, since the design work has been completed, it is estimated that the production license and airworthiness license can be obtained in two years, at most three years, right?" ”

"Almost," Chen Geng said modestly: "According to the assurance given to me by the engineering and technical personnel of the Kuznetsov Design Bureau, there is almost nothing that needs to be revised, as long as there are no omissions on our side, it is absolutely no problem to complete the airworthiness certification within 3 years." Pen, fun, pavilion www. biquge。 info”

"Awesome!" Mao Donghai's face was full of admiration: "This is really amazing......"

You can't admire it!

After the design of an aero engine is completed, the next procedure is a small batch of trial production, followed by a test flight and airworthiness certification, if there is no problem, the next step is to obtain the production license and airworthiness license time, as long as some links do not drop the chain, Mao Donghai feels that two to three years is enough.

But this is not the most surprising and admirable place for Mao Donghai, what really surprised and admired him was that from the introduction of technology to now, how long has it been since Runhua Industry has completed the corresponding improvement and design work in conjunction with the Kuznetsov Design Bureau? That's an exaggeration, isn't it?

But thinking about it carefully, Mao Donghai took it for granted.

First of all, the Kuznetsov Design Bureau has been playing with the NK-8 engine for more than 30 years, and it can be said that they know this engine very well, and it is not an exaggeration to say that they have played this engine to the fullest.

Although the time from receiving the task of these two improved models to the present is a little shorter, the civilian NK-8 improved model is only to reduce fuel consumption and improve comfort as the improvement direction, not as in the case of upgrading from NK-8-2 to NK-8-6, requiring the thrust to be increased by nearly 30% under the condition that the engine size is basically unchanged, on the contrary, the requirements of Runhua Industry are actually reduced to a certain extent.

Secondly, Runhua Industry is rich, as the saying goes, a penny is difficult to beat a hero, nothing can be done without money, Runhua Industry is rich, but their own money is how to spend how they want, unlike state-owned enterprises, they have to apply to their superiors without spending a penny, and the flexibility is more than a step higher.

With these two points as a guarantee, after such a long time, it is indeed time for the Kuznetsov Design Bureau to come out.

"Great, great......"

Mao Donghai grinned non-stop, with the improved NK-8, Lao Tzu is still afraid of BMW-Luo Luo yarn? Do you want Lao Tzu to grovel to you again? Roll Nima's eggs!

However, Mao Donghai was more concerned about the military modification used for the H-6 improved and H-8 than the civilian improved model, and after a short period of excitement, he hurriedly asked: "What about the military model, how is it?" ”

"It will take two months," Chen Geng raised his fingers, and he couldn't stop smiling: "The design work can be completed in two more months, and it is estimated that the time to get the production license and airworthiness license is about ...... of the civilian type."

"Good! That's great! Mao Donghai slapped his thigh directly in excitement, and felt a big breath in his heart: "When we have our own high-thrust engine, see who dares to show us a look." ”

"It's too early to say that," Chen Geng shook his head, compared to Mao Donghai's excitement about the military improvement, Chen Geng's interest in this civilian improvement was obviously greater: "Our NK-8 civilian improvement is a little worse than the BMW-Rowe RB710's fuel economy, but it is much better than the JT3D on McDonnell Douglas-80/82......

"If you didn't say it, do it!"

It is estimated that Mao Donghai was stimulated by the previous attitude of BMW-Luo Luo, and without waiting for Chen Geng to finish speaking, Mao Donghai snorted: "They are willing to cooperate with us, then cooperate, if they are not willing to cooperate with us, we don't ask them, anyway, their engine will not get the airworthiness license until 1996 at the earliest, two years later than our engines, what is there to be afraid of?" ”

"That's right," Chen Geng laughed, with a cold light flashing in his eyes: "If the British and Germans are behind their backs, we will have to give up the European market for the time being, anyway, our little production capacity can't even meet the needs of the domestic market." ”

This is not Chen Geng's big words, but it is true.

The original NK-8 engine of the Kuznetsov Design Bureau, not to mention noise, but only the fuel economy that the airlines attach the most importance to, does not have any competitive advantage in this respect, as long as you understand that even the old Maozi, who has never cared much about fuel consumption, is unwilling to use it, and when the Tu-154 was upgraded to the TU-154M, the NK-8 was replaced by the D-30KU, you can know how "touching" the fuel consumption of the NK-8 is.

However, the civilian improved NK-8 is different, although the fuel economy is not as good as the BR710, but it is much better than the JT3D carried on the Boeing 737-200 and McDonnell Douglas-82. Since our air transport companies can even accept the relatively more fuel-consuming JT3D, why can't they accept the improved NK-8?

Not to mention that compared with BMW-Rowe BR710, Runhua Industrial's own NK-8 civilian improved model is not only much cheaper, but also does not need to spend precious foreign exchange!

This alone is so attractive!

Why did the Republic desperately push for the MPC-75 and the improved NK-8?

Why did the Civil Aviation Administration of China hold many meetings to recommend MPC-75 to various companies?

It's because you don't spend foreign exchange!

Mao Donghai nodded heavily: "Then it's decided, give the British and Germans with their eyes on the top of their heads a good look?" ”

When Lao Tzu likes to be a grandson!

"By the way, there's one more thing, brother, you can help me coordinate."

"You say." Mao Donghai said immediately.

"Runhua Industry lacks a suitable engine air test platform," Chen Geng sighed when he said this: "Without this thing, many projects cannot be tested." ”

Mao Donghai's brows also wrinkled: "It's really a problem." ”

In the research of aero engines, although the high-altitude state can be simulated through a specially built laboratory, so that the engine can obtain the key data of high-altitude operation at the minimum cost, so as to facilitate the design and engineering personnel to make targeted adjustments, but the real high-altitude test with the flight test platform is still an indispensable part, after all, no matter how powerful the laboratory is, it cannot fully simulate all the conditions encountered by the engine in the air, especially at high altitude.

The so-called air test platform, to put it bluntly, is actually an aircraft specially used to test the engine, this kind of aircraft is usually modified with cargo planes or civil aircraft, there is a special bracket that can hang various types of engines, and the huge space in the stomach is used to install various equipment for real-time monitoring of the data of the engine for testing, and the United States has specially modified a variety of aircraft for air test flights and data collection of aero engines, including Boeing 737, Boeing 747, etc., Lao Maozi is naturally indispensable, The most commonly used by them is an air test platform modified with the Il-76, and of course we in China also have it, and it is codenamed the 226 flight test stand, which is modified from the fourth of the four Tu-16 that we bought from the Soviet Union.

"You mean, you want to borrow the 226 flight test bed?" Mao Donghai's brows wrinkled into Sichuan characters: "That's the baby bump of our country's aviation industry, rubbing off a piece of paint, it is estimated that someone will find you desperately......"

"No, no, no, I don't plan to borrow our 226 platform," Chen Geng waved his hand and said, "I mean, can the country dismantle all the military combat equipment from those H-6 that has been used for a long time and sell it to us, and we can modify a flight test platform?" ”

"You guys build your own flight test platform?" Mao Donghai's eyes widened: "Brother, do you know how expensive this thing is......

"We have money in Runhua Industry." Without waiting for Mao Donghai to finish speaking, Chen Geng said: "As long as the problem can be solved with money, it is not a problem." ”

"......" Mao Donghai was so hung that he was choked to death by Chen Geng's words!

Rich is amazing, huh?

If you have money, you will be a cow X?

You can't be so rich if you have money, right?

Mao Donghai was indignant in his heart.

No matter how indignant he is, Mao Donghai actually knows very well that being rich is great, being rich is Niu X, and being rich can of course be able to get rid of it - just like Chen Geng in front of him.

Without waiting for Mao Donghai to speak, Chen Geng continued: "I think that buying a second-hand H-6 can be cheaper, but if it is not suitable for the above, and I am worried that even such a H-6 will be in danger of leaking state secrets, then it doesn't matter, didn't the Soviet Union use the Il-76 transport plane to install five Il-76-LL engine air test platforms?" It just so happened that the Soviet Union was in chaos during this time, so I'll see if I can find a way to get one back. ”

Mao Donghai wants to scold again: It's great to be rich? If you have money, you will be a cow X? Is it so hard to be rich?

But Chen Geng really began to think carefully about whether to find a way to modify a H-6 as an engine air test platform, or directly find a way to get an Il-76-LL engine air test platform from Lao Maozi: Lao Maozi's Il-76-LL above, all kinds of test and testing equipment are readily available, buy it back and modify it a little to use, the only trouble is that all the display and interface are in Russian, but with the number of Russian engineers in Runhua Industry, It's not a big deal either.
