PT6A series turboprop and PT6B series turboshaft engines are the world's most famous aero engine manufacturing giants: Pratt in Canada. Whitney's fist products are widely used in the field of civil and military aircraft in the world, but few people know that these two series of engines with a total of more than 30 models are actually based on the same core machine of Pratt & Whitney.

Lin Hongfei didn't know the difficulty of building aero engines, otherwise the republic's manufacturing capacity and level in the field of aero engines would not rank last among all the countries in the world that can independently manufacture aero engines, but his idea is very simple. Whitney can make PT6A series turboprop engines and PT6B series turboshaft engines on the basis of PT6 core engines, and become a cash cow of Pratt & Whitney for up to 30 years, and it seems that there is no problem with this cash cow for another thirty or forty years. It has also developed two series of various types of aero engines? Anyway, the core engine of the turboshaft engine and the turboprop engine is basically the same, and it does not require much adjustment.

Whether it is possible for a core engine to maintain its long-lasting vitality for decades depends on whether the initial design is good enough and has deep enough potential for improvement to improve the performance of the core engine and the turboprop and turboshaft engines built around the core engine through continuous improvement...... Just like the 4G63 engine, which is known as the "civilian modification artifact", although the initial design is very average, it has great potential for modification, and it can naturally have a long life cycle. Otherwise, it can only be like the aircraft engine industry of the republic.

Hearing Lin Hongfei's words, Chaprekin was stunned for a moment.

Not only Chaprekin was stunned for a moment, but also the staff members who gathered around the laboratory...... After achieving such great results, they all wanted to hear what rewards their boss would give them, but what they didn't expect was that their boss would come up with such an idea.

"Can't you?" Lin Hongfei was stunned for a moment.

He thought about it carefully, thought of the Mitsubishi 4G63 in little Japan, and felt that his thinking should be fine, although the principle of turbine and piston internal combustion engine is different, but since they are both power machinery. The most basic principle is always the same, as long as the initial design is good enough, there is no reason why it can't be like Pratt & Whitney's PT6A series turboprop engine and PT6B series turboshaft engine, which can become an evergreen tree in the field of aero engines in the world, right?

"No problem! Absolutely! Chapregin, who came back to his senses from Lin Hongfei's idea, turned red with excitement. As soon as he grabbed Lin Hongfei's hand, he didn't let go, just like the underground party in the movie finally found an organization. "Boss. You're the greatest boss in the world, do you know it? You have shown us where we are headed for decades to come. ”

Not really, right? I just made a suggestion, and this suggestion is so great and magical? Lin Hongfei had some doubts in his heart, and even more doubted whether his suggestion was too reckless, and whether the core engine of this engine really had such deep development potential, but listening to the excited shouts of the Belarusian and Ukrainian experts around him who were chanting "Ula" and kept shouting to celebrate with a second pot. Lin Hongfei finally affirmed a little bit in his heart, it seems that his suggestion is really feasible?

It seems like it's really doable.

"Well, since you think it's feasible, let's do it." Lin Hongfei thought very simply. What I am good at is not aero engines, but since there are people who are good at this, or their own soldiers, there is no reason to meddle too much, more encouragement is enough, "I am looking forward to everyone coming up with new products one after another, and building our company into the world's top aero engine supplier...... If there is anything that needs to be added, whether it is equipment, manpower, or whatever, form a written document and send it to me. ”

"Ula ......"

In response to Lin Hongfei, there was another burst of enthusiastic cheers.

For these other researchers, who are mainly Ukrainian and Belarusian, supplemented by the republics of the former Soviet Union, it is simply a paradise for researchers to have sufficient equipment to conduct their own research, not to worry about their own life problems, and to have a clear research direction!

The most important thing is that this commitment from the boss means that the problem they were worried about before has finally been solved! That's really ...... A happy thing worth pouring three bottles of two pots.

"Boss, in addition to adding some equipment and recruiting more people to enrich the experimental value, I think it is necessary for you to set up a materials laboratory, especially a material testing laboratory for the study of alloy materials for aviation," taking this opportunity, Chaprekin suggested to Lin Hongfei with a serious face, "The main materials of this engine we are producing now are all imported, and you also know that the price of this kind of alloy materials is very high, and the profit of individual materials is more than 1000%, If we can use our own materials, the cost can be greatly reduced, the production capacity can be greatly increased, and most importantly, we can not be controlled by others. ”

As the head of the aviation laboratory, Chaprekin is undoubtedly qualified, and while other experts in the laboratory are still thinking about solving the problem of the engine, he has already begun to think about the long-term development of the company, and it is clear that Chaprekin has been thinking about this problem for a long time.

For this suggestion, Lin Hongfei of course does not think there is anything wrong, as an engine designer, he knows too well the importance of materials, not to mention that he has consciously searched for the materials research institutes of the former Soviet Union in the past two years, and the data alone filled two large warehouses, and it cost him a huge amount of manpower, material and financial resources to collect these materials. Regarding the reality that the Republic of the Republic in later generations was controlled by people in terms of materials and power, Lin Hongfei was simply too impressed.

"Xie Lu, thank you for your suggestion, Lao Cha," Lin Hongfei patted Chapregin on the shoulder, "Rest assured, the issue of establishing a materials laboratory has been put on the agenda, this will be a comprehensive materials laboratory, not only a variety of aviation materials, high-temperature resistant metal materials, but also a variety of new composite materials," he waved his hand, "The company's next focus is to enrich your aviation laboratory and metal and composite materials research laboratory, and strive to make use of the company's information." ”

"So boss, you thought of this a long time ago? That's good, that's good, then I don't have to worry about it. A smile appeared on Chapregin's face, of course he knew that his boss had been "tirelessly" and tirelessly collecting all kinds of research materials from the various republics of the former Soviet Union in the past two years, especially the research materials in terms of materials, which was the top priority of his boss, such a comparison, he felt that it was better to cheapen his boss...... It's not that my boss didn't give money.

"That's right," Chaprekin added, "Also, the corresponding software control technology should also be developed, I think that the future aviation field will gradually replace the traditional fly-by-wire analog control technology with computer software control technology, we all believe that this is the future development direction of aero engines and aircraft." ”

Well? Do you even have this Chaprekin in mind?

At this moment, Lin Hongfei was really surprised, he didn't expect that these aviation experts and engineers of the former Soviet Union would be so far-sighted, you must know that Soviet-made aircraft, especially Soviet-made fighters, have always been known for their strong air mobility capabilities, and electronic technology has never been their strong point, but now Chapregin actually told himself that they, the Soviet engine and aircraft experts, collectively believe that the development direction of aero engines and aviation aircraft is computer control? Lin Hongfei, as a person who has come over, of course knows this, but it is not easy for people who are in a puzzle to see this point clearly at this time, and in the years before the collapse of the Soviet Union, this point was particularly critical.

But the Soviet aviation experts present nodded their heads again and again with a look of approval that could not deceive people, and they really thought so in their hearts.

"Of course! In the future, computer control will become the mainstream, I fully agree with that," Lin Hongfei nodded heavily, but he also had his own difficulties, "but I don't know much about this aspect, if possible, I hope you can recommend some talents and experts in this area to the company...... The company will always encourage this kind of behavior, and I believe that everyone knows the corresponding way of encouragement, so I will not say more. ”

Speaking of this, Lin Hongfei paused slightly, and he suddenly realized that he had ignored one of the most important questions, "Lao Cha, what is the cost of our engine?" What is the estimated pre-sale price? ”

"The cost is 70,000 US dollars, mainly because the material of the turbine blades is still made of imported alloy materials, if we can produce it ourselves, the cost can be further reduced," Chaprekin is indeed the person in charge of the aviation laboratory, and the technical indicators of this engine are like a few treasures, "If the problem of material source can be solved, it is estimated that the cost can be reduced to 50,000 US dollars, and if large-scale production can be realized, the production cost of 40,000 US dollars can be expected. Selling for $150,000 is not a problem at all. (To be continued......)
