Chapter 841: A Difficult Choice (Part II)

Yang Hui did not guess wrong, the German side quickly reflected it, and they also knew that this time they were going to develop a medium-sized front-line tactical transport aircraft, so they proposed to hear what the situation of this second plan was. Pen, fun, and www.biquge.info

With a mysterious smile, Yang Hui offered the second killer move: "Then now is the second plan, according to our calculations, in order to achieve a short-distance take-off and return of 12 tons of cargo in the field airport, this requires us to have more powerful power, CG-2000 engine 7.8 tons of thrust at this time is not enough, we finally came to the conclusion that there must be four turbofan engines with a maximum thrust of at least 9 tons to meet the use requirements." ”

As soon as I heard that this was to increase the thrust of the engine, the Germans reacted first but it was a little different from what Yang Hui envisioned, and this Nima German is indeed a little interesting, not to mention anything else, then there is a ready-made engine available now!

Someone in the German team immediately jumped out, almost busy to offer treasure: "A single large bypass turbofan engine with a thrust of at least 9 tons, this thing is easy to say!" Our MTU company has such a mature engine in production, and the whole series has been delivered 1,000 units, and then it will be necessary to make some adaptable improvements for the new Zhongyun. ”

This is really a little confusing, it seems that the Germans in our script should not know that there is a CG-2000-2 engine, where does it come from the confidence to say that there is a mature engine at hand, and it is also a kind of production to deliver 1000 units, the entire CG-2000 engine has only been delivered for a long time, and it is only a three-digit production number, where did it come from.

Seeing that Yang Hui hadn't reacted at this time, the chief engineer of Kinchenko on the side reminded in a whisper: "MM's MTU company has participated in the V-2500 turbofan engine project, of which the V-2500-D5 engine was originally a 97DAN (10-ton class) engine developed for the MD90 aircraft in 89, and now it has indeed completed all the development work, but this D5 improved model has definitely not been put into use on a large scale. Their so-called delivery of 1,000 engines should not be possible now, at most, the entire V-2500 series of engines has recently exceeded the order of 1,000 units. ”

This is really an old driver, this has just entered the field of civil aircraft development for less than a few years, and he already knows these civil aviation engines well, and this time if it weren't for Jinchenko's reminder, Yang Hui really forgot that the MTU company did invest 140 million US dollars in the development of the V-2500 engine, so it was only to get 12.4% of the shares of this series of engines, so now the MTU company is really not bragging to say that they have a suitable engine.

Then Yang Hui was a little embarrassed at this time, did Nima, the German guy, have water in his head? Leaving the CG-2000 series, which they occupy 40% of the shares, not to use the V-2500 series engines, and the CG-2000 series engines also have a production line in MTU, which is much better than the V-2500 only has a production line in Derby, England.

At present, the atmosphere in Europe is not to say that the most important thing is to pay attention to the pull of large-scale projects on the country's economy, pay attention to how many production jobs can be created for the country, and be able to .....

Yang Hui also had all kinds of grass and mud horses in his heart, but he forgot that the MTU company at this time really didn't know that the CG-2000 engine had a thrust increase plan, after all, the Germans had used the most advanced technology they could come up with when developing the CG-2000 before, and it was only less than ten years, so it was said that the CG-2000 had increased to more than 9 tons.

If nothing else, at least the current Germans are not capable of achieving such a large increase without major changes to the engine's low-pressure system.

All because at this time the Germans themselves have fallen into a misunderstanding, in their opinion, they did not expect that the technological progress of the southwest side of AVIC is so fast, the new high-temperature turbine coating is up, the core machine is directly up half a step, and it is just a simple thing to increase to 9 tons.

At the beginning, when Yang Hui actually heard this, he also wanted to directly tell the Germans about the 2000-ton increase plan of the CG-2000-9 engine, but after thinking about it, he wisely chose to keep the project secret.

At least considering that there was already a CG-2000 production line on the German side this year, the new China Transport would definitely supply orders from the German side in the first few years. Using the CG-2000-2 engine as the power, it must also require the engine to be assembled in Germany, and at that time, the southwest side of AVIC will only provide the core engine at most, and it can't sell the entire engine to make a few dollars.

In contrast, there is no need to expose the CG-2000-2 program, after all, once the CG-2000-2 engine is exposed, it means that the new CG-2000 series engine has a certain threat to the CFM-56 and V-2500. 、

At the same time, the aircraft manufacturer can also roughly guess the C-818 project, at that time, the problems faced by the entire AVIC Southwest are really all kinds of head-scratching, and now it can continue to cat's waist for a few years, and it is the best policy to secretly accumulate strength.

What's more, if this new China Transport is only counting overseas orders, the number of purchases in the early stage is not much, at most 200 Dingtian, although the order of 800 engines is attractive, but for the current AVIC Southwest, in fact, it is not necessary to take this big risk, anyway, now the core machine orders are full after 2000.

In this way, Yang Hui already has a plan in his heart, since the Germans think that it is feasible to use the V-2500-D5 engine, then let them be, and there are still some benefits to using the V-2500-D5 engine at that time.

Now AVIC Southwest only needs to participate in the aircraft research and development project, and finally can get the entire set of design materials of the aircraft, to ensure that the domestic production of this aircraft when the time comes, can quickly replace the CG-2000-2 engine that has been finalized at that time, everything will be fine, and such a way of not knowing the ghost, presumably not many people can easily see.

And when the time comes, AVIC Southwest will not participate in the engine problem, and only the technical support for the overall design of the aircraft will appear in the project, and the sense of presence will be less at that time, so that the funds that need to be invested in the project will not need a few dollars, which is now very good for AVIC Southwest, which needs to invest heavily in the light four projects.
