He knows very well that this great discussion has unified thinking to a considerable extent, and if he can play a role in this activity of unifying thinking, it can only be regarded as a contribution to national rejuvenation, but at the moment, he has more important things......

"So the current situation is that there is really an urgent shortage of turboshaft shaft engines in China for this kind of 2000 shaft horsepower level, but many national defense scientific research projects have a higher priority than this, if our project only relies on financial allocation, it will probably be a little difficult to start, right?" After listening to Wang Dazhi's report, Chen Geng summarized it for her.

Wang Dazhi nodded hurriedly: "Yes, that's pretty much it." ”

Chen Geng groaned.

From his personal point of view, of course, he hopes to apply for the state's financial allocation for the work of the AI-222-25 engine's turboprop and turbine shaft, for Chen Geng, who has rich experience in the system, he must not be polite in the matter of the state's financial allocation, the cake is so big, if you don't fight for it, you will definitely not have your share, and those units that have won it will laugh at you mercilessly: that guy is a fool, he doesn't know how to ask for free money.

But having said that, what Wang Dazhi said is also true, compared with the advanced engines that are most urgently needed by these fighters such as "Kunlun" and "Taihang", the turboshaft engine for helicopters is really not in a hurry, but it is ......

"How's the talk with Xifei?" Chen Geng asked, "What is Xifei's attitude towards equipping our engine?"

Although Xifei verbally promised to be very good, but this kind of thing still has to be implemented on paper after all, but in the process of implementing this link on paper, it is more difficult, and the negotiation process is not very smooth, Chen Geng also understands very well, first of all, the P&W Canada PW127J turboprop engine on the 7-200 is already a very advanced and mature, And the engine has many years of experience in foreign countries, after a number of aircraft manufacturing companies for twenty or thirty years of use of a number of models, except for the price of a little more expensive other problems, and for a civil aircraft engine, the price is not a problem, reliability, safety and fuel economy is what they value most.

Compared with the PW127J, the situation of the turboprop engine that COMAC plans to improve on the basis of the AI-222-25 turbofan engine is very embarrassing: not to mention reliable and safe, this engine has not yet appeared.

This is more embarrassing: you dare to worry about wearing an engine on our plane that hasn't landed yet?!

That is, the relationship between COMAC Group and Xifei is really good, otherwise as soon as this proposal comes out, it will be beaten out by Xifei: Are you planning to fly us west to the rhythm of the death pit?

From this point of view, Xifei is still willing to negotiate with COMAC in this case, which is really to save face, even if the negotiation process is very unsmooth.

"It's not very smooth," Wang Dazhi smiled bitterly, and said honestly: "You also know that our engine has not yet appeared, let alone obtained the airworthiness certification and type certificate and production license of CAAC." ”

CAAC, Huaxia Civil Aviation Administration, as an aero engine developed by Huaxia enterprises, if you want to fly on the aircraft, you must pass the CAAC airworthiness certification, obtain the type certificate and production license, and prove that you are a qualified product that meets the requirements of the Huaxia Civil Aviation Administration, which is very easy to understand, right?

As for Chen Geng, he is very open to the financial allocation this time: "Since the state's financial allocation is not easy to handle, then we will do it ourselves...... Mr. Rabinovic said how much money would be needed?"

"It's about between 1.8 and 260 million," Wang Dazhi immediately said: "In addition, even if it is developed with the core machine of AI-222-25, it will take at least about 3 years." ”

This amount of investment, so that Chen Geng relieved a lot, he is very clear about the future of China, how many Mi-17 and Mi-171 will be purchased, and later is to vigorously develop the 10-ton general helicopter Z-20 and heavy armed helicopter Z-10, and Z-10 and Z-10 heart disease has not been solved, it doesn't matter if you can't sell it now, you don't have to worry about the sales of the engine in the future, now listen to Wang Dazhi talk about this investment, he immediately said:" Then let's invest our own money, it's sixty or seventy million a year, let's invest, but in terms of model, I suggest you take a look at the model development process of TV3-117VM series engines, in this series there is a TV3-117VMA-SB2/M turboprop engine, this engine is also the engine of the An-140 aircraft jointly developed by Ukraine and Russia.

The Ivchenko Design Bureau simply made very simple improvements to the reducer, changing this turboshaft engine to a turboprop, and we can learn from this idea. ”

PS1: Sorry brothers, please wait a few minutes.

PS2: Brothers, I'm sorry, the last chapter was hung up, and I think it's okay for a thousand years, but it's just hung up, alas, brothers, I'm sorry, I'll just look at it first, and then revise it for a thousand years.
