Saying goodbye to Wei Tianming, Wang Dazhi immediately reported the matter to Chen Geng - anyway, the boss had already woken up before, and it was estimated that he hadn't fallen asleep yet, so Wang Dazhi felt that it was nothing to quarrel again.

Changfei wants to let COMAC make a turboshaft engine on the basis of the AI-222 core machine in a few days, and match their Z-8

Wang Dazhi's report on the situation surprised Chen Geng, he pondered for a while, did not answer immediately, but asked Wang Dazhi rhetorically: "What do you think of this matter?"

"I think what Chief Engineer Wei said makes sense. ”

"Oh?"

"Xifei attaches great importance to the Y-7 series aircraft," Wang Dazhi said: "I just finished the New Year, at a meeting in the industry, I talked with some leaders of Xifei about the Y-7, they are very optimistic about the future of the Y-7 in the civil aviation market, and believe that in the next ten years, at least 200 foreign and domestic Y-7s of various types can be sold, if it is 200 Y-7, and then counting the spare engine, Xifei alone can digest 460 engines, and then counting the international market, the prospects are very optimistic."

In addition, we can also learn from Pu· Hui Canada, on the basis of the PT6 core engine to develop the A type of turboprop and the B type of turboshaft, the potential of the core engine of AI-222-25 is good, the power range from 1500 horsepower can be covered to 4000 horsepower, across two power levels, the most important thing is that we can win the engine orders of Zhi-8 and Wuzhi-9, you also know, the reliability and failure rate of the turboshaft-6 engine on the Zhi-8 make the above too much headache.

As for the Wuzhi-9, because of the lack of power of the turboshaft-8, according to our calculations, if we want to meet the above firepower requirements, not only can we not install armor to protect the crew, we cannot install a night vision system, but also have to reduce weight, if there is a 1500 horsepower turboshaft engine even if it is 1200 horsepower, it is not a problem, it can be made into a 'complete body' armed helicopter ......"

Chen Geng groaned, he also knew that the military had enough of the vortex-6.

How much of a headache is the reliability of the vortex-6 for the military?

Let's talk about one of the most important indicators: the first renovation period and the renovation interval.

The turboshaft-6 and turboshaft-6A have only 600 hours between the first rebuild and the overhaul, which means that the engine must be overhauled after 600 hours of use, otherwise the engine will not be able to continue to be used.

Not to mention that this data is compared with the American T700, which has reached 6,000 hours in the first period, and the PT6A series, PT6B series and PW124125126127 series of Pratt & Whitney Canada, which have a first period of 2,500 hours, even compared with some of our own engines, it is also greatly inferior: the first period of the turbojet-8 turbojet engine on the H-6 bomber produced after 82 years has reached 800 hours.

The AI-222-25 turbofan engine also has an overhaul interval of 1,500 hours, and if the turboshaft engine and turboprop engine are developed based on the core engine of the AI-222-25, the overhaul interval cannot be less than 1,500 hours, right?

"That's it......"

After pondering for a while, Chen Geng finally spoke: "You first discuss it internally, and then make a detailed research and analysis report, and make a survey of the domestic and foreign market conditions of turboshaft engines and turboprop engines at this power level, and see how big a piece of cake we can get in it. ”

"Understood," Wang Dazhi immediately responded: "Chairman, rest assured, we will strictly analyze and investigate the market situation." ”

This project is not on it, once it is determined to be launched, the required R & D funds are at least 1 billion as a unit to calculate, if the project is not successful after the launch, the loss, it will be even worse, not to mention that the current commercial aviation group is not called wealthy, even if it is the real wealth of Rolls-Royce, General Electric and Pratt Whitney Big Three, do not dare to pat their heads, say "this project is on the ground", there must be a rigorous, reliable product market research and analysis.

"Then do it," Chen Geng said encouragingly: "Lao Wang, if your suggestion is feasible, our company can be regarded as adding another fist product, so that if the group hires you back as a consultant, no one can say what is wrong." ”

That's right!

Wang Dazhi reacted suddenly: he is about to reach the age of retirement, although he feels good mentally and physically, but now I don't know how many people are staring at the chair under his buttocks, and nine times out of ten he will retire.

After working all his life, he suddenly retreated, it was impossible to say that Wang Dazhi was not a little afraid and unwilling in his heart, but at this time, Chen Geng's words suddenly reminded him: That's right, as long as I get this done, the group can also hire me back as a consultant, with my results, who can say anything?

He immediately said: "Chairman, don't worry, I will personally keep an eye on this project." ”

"Come on!"

After saying a few more words, Chen Geng hung up the phone.

The phone hung up, but Chen Geng groaned, he was not so optimistic about the derivative model of the turboprop version, others did not know the development of the Y-7 series, but Chen Geng knew, whether it was the Y-7-100 that was put into use now or the Y-7-100 that was in test flight, or the new boat 60 and the new boat 600 in the back, MA700, the sales situation is not very optimistic, in the case of domestic regional aviation is pressed by the railway, the Y-7 series aircraft basically has no prospects in China, all rely on policies and administrative orders to sell a few, as for the foreign market, hehe......

Don't think about the European and American markets, you can only sell to poor brothers in Africa and South America, and with the personality of those poor B airlines in Africa and South America, they are willing to take good care of the Yun 7?

The several aviation accidents of the Yun-7 and the subsequent MA 60600 series overseas users were almost all caused by the improper use and maintenance of the aircraft by these poor B airlines in the third world - or rather, they had no maintenance at all - but in this way, it further tarnished the reputation of the Chinese-made aircraft.

With such strong opponents as ATR and Fokker, how can the Y-7 compete beyond political purchases?

As for Fokker, yes, Chen Geng is the majority shareholder of Fokker, but he is first and foremost responsible for the interests of Fokker, and Fokker will switch to the turboprop version of the AI-222-25 for its Fokker F28 under the same comparable circumstances - it is not known when it will be.

However, although he is not optimistic about the turboprop version, for the turboshaft version, thinking of the Z-8, Wuzhi-9 and the future Z-10, Z-19, AC313, Chen Geng can't help but get excited: This is the future.
