To say that Yang Hui's technical list is indeed very tempting, especially the DSI bulge inlet technology is constantly drooling, can sell this technology to MM company, but also to add the camber double vertical tail technology that Germany itself has not solved before, as well as a variety of aerodynamic design data of the whole machine, the quotation of 600 million US dollars is also more in line with the market situation.

But in any case, even the Germans in the nineties were quite tyrants in the whole of Europe, and the dollar was a little hard to depreciate at this time for various reasons, but no matter what, the 600 million offer is still a little unacceptable for MM company, even if the AT-2000 project is backed by the German army and government, but the money is not spent like this.

"This is not good, just these pneumatic design data will cost 600 million US dollars, in fact, you must also know that these technologies are not insurmountable difficulties for our MM company, we chose to buy technology in order to be able to save the research and development cycle, but this does not mean that we will accept the sky-high asking price, now only give 200 million US dollars, if we don't want these materials, no one is willing to spend money to buy."

Germany is willing to buy related technology, but is only willing to give 200 million US dollars, which is really directly cut off more than half of the offer, and it is really the king of bargaining. In the end, Yang Hui felt that he couldn't stand it, and after thinking about it, he came up with a more compromise solution.

"In this way, since you are not willing to spend too much money on the purchase of these aerodynamic design materials, then we are pragmatic, about the most important and key quotation of the DSI bulge inlet information, we will no longer sell a full set to you, but by AVIC Southwest according to the requirements of the direct design of the fighter required by the three-dimensional design data of the inlet duct, specific design methods, software, etc., are not within the scope of this technology sale."

At the beginning, Yang Hui actually planned to sell the design technology of the DSI air inlet together, anyway, the whole of Europe will not be able to design military fighters in the future, and it is useless to give them the design method of the DSI air intake, and there is not much threat to the Republic after the sale, but now the Germans are not willing to give more money, so they will definitely cut these core technologies.

Not to mention, the German really agreed to the plan after thinking about it, and it can be seen that the German is actually just planning to do a business, or the Germans think that there will be more advanced air inlet technology to be studied in the future, and this DSI air intake will not be long in the future!

"We agree to this plan, this time there is no need for the transfer of a complete set of design technology, and we can only accept a price of 300 million US dollars at most, but you need to transfer the previous full set of fourth-generation aircraft data, and if there are problems in the subsequent aerodynamic design, you need to give technical assistance free of charge throughout the whole process, until the aerodynamic design of the aircraft meets the requirements."

Although the price of 300 million US dollars is only half of what was expected at the beginning, this is because the core technology was not sold, and on the other hand, Yang Hui did not think that the Germans would accept the offer in its entirety at first. More importantly, the design data on the aerodynamics of the fighter is only a small beginning, and the subsequent technical sales of various designs, Yang Hui can ensure the ******** of the Germans.

Since he has made up his mind to make a good quick buck, Yang Hui is more willing, and then in terms of the most important power system of the fighter, he will definitely bite the bullet and not let go, and the Germans are helpless, it is really the temptation of the engine of AVIC Southwest. It's too confusing.

The specific situation must depend on how dark Yang Hui's heart is: "We can provide AT-2000 with the best military thrust engine in the southwest of AVIC, that is, the ultimate improved model of the turbofan 12 series, turbofan 12C engine: thrust ratio 10, With an intermediate thrust of 7.3 tons and a maximum afterburner thrust of 11 tons, we expect it to be able to reduce fuel consumption to about 0.73, and such thrust figures have even reached the level of the third-generation high-thrust turbofan engine, which is not a problem to propel the AT-2000 to achieve supersonic cruise. ”

In fact, when talking about this, Yang Hui also did a little trick, at least in terms of this engine to promote the AT-2000 to achieve supersonic cruise, you really want to say that the ability must still be there, but this is only limited to the AT-2000 without an external attachment point, if the AT-2000 hangs the stealth weapon cocoon bag arranged by Yang Hui, it is absolutely impossible to ensure supersonic cruise capability at that time, which is probably the kind of transonic cruise combat capability of the F-35, Perhaps it can reach a cruise flight index of about Mach 1.2.

However, this is to say, to be able to reach 11 tons of powerful thrust, it is indeed the capital to pretend to be forced once, at least at this time the MM company has been drooling for a long time, the performance of the engine is simply the existence of the sky, the so-called EJ200 engine and this turbofan 12C comparison, although there are also some of their own uniqueness, but in terms of the most important thrust indicators, it must be more appropriate to use the turbofan 12.

For the technical capabilities of AVIC Southwest in aero engines, the German MM company is still more recognized, before from AVIC Southwest turbofan 10, CG-2000, plus the current turbofan 12B engine has publicly stated that the project research and development has entered the middle stage, which shows that the follow-up turbofan 12C can also be expected.

"Okay, we also looked at the data indicators of the turbofan 12B engine before, according to the progress you gave, there must be no problem for the AT-2000 to use this engine as a test flight stage, so in the indicators of the turbofan 12C engine, we still have higher requirements, for example, as the standard configuration of the fourth-generation fighter, we require three-dimensional vector thrust technology, can you do it?"

This requirement is really not too much, the turbofan 12C is equipped with three-dimensional thrust vectoring technology is also something in the plan of United Aero Engines, and the three-dimensional vector thrust technology is also a reserve technology that the company has overcome, if necessary, it will be installed directly, which is not as difficult as it seems.

"There is no problem, for the 3D vector thrust technology, our company has been researching the relevant technology for a long time, and this technology is indeed the standard configuration used in the fourth generation aircraft. But then again, you plan to use 3D vector thrust this time, which means that you have to realize the integrated cross-linking of fire and fly thrust, and it is still a bit difficult to realize the technology of this project, but you are confident that you can do it? ”

To be honest, even the current AVIC Southwest itself does not dare to say that it has achieved this technical difficulty, after all, this technology first requires the engine full authority digital control system technology, and then the thrust vector technology, and it is very embarrassing that the engines of AVIC Southwest have not yet reached this level.

The most basic technical requirements are not yet available, and a company as strong as AVIC Southwest has developed rapidly, it can only take its time step by step. (To be continued.) )
