Lin Hongfei didn't know that the discussion on his administrative level in the capital had ended in vain, of course, with the temperament of Boss Lin, even if he knew Lu Dao, he would not take it seriously, and now he was more concerned about whether the hands and feet of the British were clean......

"Boss, it can be preliminarily determined, there is no problem with these engine materials." Facing Lin Hongfei's gaze, Christianicheniko's face was full of joy, "As for whether there is a hand or a foot in the specific details, it requires us to actually produce an engine and conduct actual verification in the process of production and manufacturing." ”

"Hard work," Lin Hongfei nodded with a smile, "Mr. Christianiko, you have worked hard during this time, according to the company's regulations, you and your team can enjoy half a month's vacation." ”

He knew very well that as the most brilliant jewel in the aviation industry, the aero engine was too sophisticated, as Christianico said, if the rolls-Royce company had done something in some small details, it would have been impossible to find out anything, only to produce a batch of engines himself, and in the process of production and manufacturing, he would find out whether the information provided by the British had been manipulated.

"No, boss, I don't need a vacation, I want to get back to work quickly," to Lin Hongfei's surprise, Christianico actually refused his vacation, he danced with his hands, without hiding his excitement, "God, I have to admit that the RTM322-9 is much better than the TV3-117PM in terms of design, I want to build this engine...... Boss, do you know the truth? Relying on our low labor costs, our engines will have greater market competitiveness than T700 and TV3-117 in the international market...... Because of this, we can sell at least 300 more engines! ”

For a product that costs millions of dollars, being able to sell 300 more units is already a staggering number. And Krishcheniko, as an engine design expert of the former Klimov Design Bureau, naturally has enough reason to be excited: in the former Soviet era, limited by the confrontation between the two powerful groups, although they wanted to learn and learn from their opponents, it was impossible to get what they wanted, but now, in front of their eyes, there is a complete set of RTM322-9 turboshaft engine all the information, which can compete with General Electric's T700 turboshaft engine. One of the world's finest turboshaft engines to date.

The enthusiasm of his employees is high, and Lin Hongfei is of course in a good mood. But he is more concerned with one other thing, "Mr. Christianikov, if we develop a turboprop engine on the basis of this engine core machine, and Pu. What are the advantages of PW127 compared to Hui Canada? ”

General. The PW127 series turboprop engine produced by Hui Canada is the most used turboprop engine in the range of 2,500 hp to 3,200 hp in the world. Coincidentally, the power coverage of the core engine of the RTM322 turboshaft engine is also within this range. And so it goes. This makes Lin Hongfei unmoved.

"RTM322 is more fuel-efficient!" Christianico said without hesitation, and he was simply at ease with all kinds of data, "If there is no problem with the data provided by the British, compared to PW127, RTM322 can save about 7% of fuel; In addition, because of the light weight. Because of the reduced weight of the engine, the aircraft using the turboshaft engine developed from the core engine of the RTM322 can fly about 200 kilometers longer than the PW127. ”

The fuel saving of 7% is not to mention, because the weight is lighter. To be able to increase the range by 200? Lin Hongfei was taken aback, "Is there such an exaggeration? ”

"Well, there may be errors, but it won't be too bad," Krischinico nodded, and said with great certainty, "The weight of the RTM322-9 is 240 kilograms, and the weight after modification to a turboprop engine will not exceed 350 kilograms, and the weight of the PW127 is 481 kilograms, which can save 262 kilograms of weight based on the use of two engines in an aircraft, which is enough to ensure that the aircraft can fly about 200 kilometers more...... It is worthy of being an old aircraft engine company, with a deep heritage, and it is indeed much more advanced than the Klimov Design Bureau in terms of design ideas, and there is the most important point. ”

"Huh?"

"We found that this engine was an all-rounder," says Christianico, "not only could a turboprop and a turboshaft engine be developed on the basis of the same core engine, but a free turbine could be converted into a gas turbine with a fan, and thus a turbofan engine could be derived." Therefore, in fact, the RTM322 engine series is intended to cover three series: turboshaft type, turboprop type and fan type. ”

"Really?" In any case, Lin Hongfei, who didn't expect such a result, can only be described as ecstasy in his heart: he just wanted a turboshaft engine, but he didn't expect to get an additional turboprop engine and a turbofan engine? That's a ...... Hahaha...... God has eyes!

"Of course, I still have that confidence," Christianico shrugged, "but my dear boss, I need to remind you that although this engine can be developed into a turboprop engine and a turbofan engine, it will still require a lot of financial investment, and I hope you are mentally prepared for this." ”

"I know it." Lin Hongfei nodded, of course he knew that there was a core machine with great potential was the infirmary, but if he wanted to develop three different types of engines on the basis of the same core machine, there was still a lot of work to be done, but in this case, was it necessary to introduce AI-22 turbofan engines from Ukraine?

After a deep sigh, Lin Hongfei opened his mouth and asked, "Mr. Christianiko, in your judgment, if you use this core machine of RTM322 to develop a turbofan engine, what is the maximum take-off thrust and cruising thrust of this turbofan engine?" Well, just give me a rough number. ”

"This ...... I can't give an exact number, but if you can make a comparison, if you can achieve a large bypass ratio of more than 6, its performance is about the same as that of the D-36 turbofan engine, but the fuel consumption can be reduced by at least 30%! Speaking of this, a trace of inexplicable sadness flashed in Christianiko's eyes, "After all, D-36 was designed in the 60s and produced in the 70s, while RTM322 was designed in the mid-80s and just obtained the airworthiness certificate in the early 90s. ”

Is there such a big gap? Lin Hongfei was taken aback! I couldn't help but feel a little dazed in my eyes: should I develop a turbofan on the basis of the core engine of the RTM322 turboshaft, or continue to dig into the potential of the D-36?

At this moment, Lin Hongfei fell into confusion.

"Mr. Lin, you may have misunderstood," Lin Hongfei's serious confusion fell into Christianiko's eyes, which made Christianico feel bad in his heart: the company's CEO's thinking has fallen into chaos? There's nothing worse than that," I mean, the turbofan engine developed from the core engine of the RTM322 turboshaft engine maximizes its potential, which is only equivalent to the latest modification of the D-36: D-436, but as a turbofan engine that uses a three-rotor scheme at the beginning of the design, the D-36 has much greater potential than the RTM322-9. It could not have developed a turbofan engine with a maximum thrust of more than 200 kN in any case, and the engine of the thrust class D-436 was his limit. ”

"I see!" Lin Hongfei wiped the sweat from his forehead, and Boss Lin realized that he seemed to be in a terrible mood just now, if it weren't for Christianico's words, Lin Hongfei was sure that something would happen, and glanced at Christianico gratefully, "Mr. Christianiko, thank you for your reminder, you have done me a great favor!" ”

Christianico smiled innocently, "Boss, it's a pleasure to work under you, and I hope to be able to continue this pleasure until the day when I can't do it anymore." ”

"I'm also looking forward to seeing a meritorious employee show up." Lin Hongfei, who understood what Christianico wanted, couldn't help but be stunned for a moment, and then smiled, this can be regarded as giving him a promise. Immediately, Lin Hongfei changed the topic and asked him, "Mr. Christianiko, how long do you think it will take for us to build the first prototype?" Well, on the premise that the information provided to us by rolls-Royce is correct and the company guarantees the investment. ”

"Three years!" Christianiko's eyes lit up, and he said confidently, "Boss, I'm not bragging, as long as I guarantee the investment of funds and ensure that there are no problems with the data, I promise that the first prototype will be manufactured within three years, and in five years at most, it will be finalized!" ”

"Three years to build a prototype, five years to finalize?" Lin Hongfei's eyes were bright and scary, and he patted Christianiko on the shoulder, "Okay!" Mr. Christianiko, I await your good news...... You should be very clear about the company's special contribution system, I won't say what you will get if you can succeed, I wish you success! ”

"Boss, I will!" Krischenniko nodded heavily, his eyes full of determination.

When I was invited by my boss from the Klimov Design Bureau, I was disheartened and planned to return to China after seeing how much attention the country attaches to helicopters. (To be continued......)
