Sent away the chief engineer Chen who came to inquire about the news from Xifei, Yang Hui also felt a little emotion in his heart, to say that the accumulation of the aviation industry of the Republic is not bad now, and there seems to be no problem with the identity of the five hooligans of the United Nations.

There are so many plans in this bidding, and there are some drooling highlights, which makes Mr. Li feel a lot of pressure when he speaks on the stage, and only Yang Hui is still happy off the stage, after all, the speech on the stage can not fully reflect the excellence of the Southwest Science and Industry Program, and the Southwest Science and Industry Program has a real killer feature that has not yet been used.

On the second day of the announcement of the temporary adjournment of the meeting, Yang Hui got up to prepare for a new day, this time he needed to go through the back door, some things are not convenient to say at the bidding meeting, military equipment should still have the most basic principle of secrecy, especially when it comes to some more sensitive technologies.

Chief Li also seems to know what Yang Hui is going to do, and he also got up early in the morning, and after preparing everything, he also sat in the hall of the guest house, just waiting for Yang Hui's arrival.

"Chief Master Li, let's go, I have already told Director Ding about today's matter in advance. The review team is willing to give us two hours to explain our ideas, and I believe that these two hours are enough time to explain our research on the stealth of fighters. ”

Yes. The reason why Yang Hui and Chief Master Li want to go through the back door this time is not ordinary, and it is about the advantages of the Southwest Science and Industry Program in terms of stealth. Of course. It can also be said that it is about the requirements of the new generation of combat attack aircraft for stealth performance in combat, as the third-generation fighter developed in the 90s, it is already regarded as the same era as the European Shuangfeng, you have not done a certain deal with stealth, and you are absolutely embarrassed to go out.

If we want to talk about the stealth performance of the third-generation aircraft, we must talk about the initiator of the concept of stealth on the third-generation aircraft: the European Joint Fighter Program. And when it comes to the entire European joint fighter program, the strange things in it cannot be said for three days and three nights, and here we only need to talk about the experience of this project in stealth and fighter generation.

The first joint European fighter program, which was only officially started in the eighties. Before that, the United States imperialism and Soviet repair had developed advanced third-generation fighters before and after, and Europe could wash and sleep except for the presence of the Mirage 2000.

For the sake of the future of Europe's aviation industry, Europe had the idea of jointly developing a new generation of joint fighters, which was the beginning of the Typhoon fighter project, during which France's withdrawal from the project and the creation of its own Rafale fighter are well known.

As the Typhoon and Rafale, which began to investigate and evaluate operational needs in the 80s and produced prototypes in the early 90s, they are already more than 10 or 20 years later than the F-14, F15, and F-16. At the end of the eighties, when the United States began the research of the F-22, the Europeans would certainly not be limited to the development of an early third-generation fighter like the F-15, so the Europeans began to study the fourth-generation fighter.

That's right, when Europe was developing the twin winds. At the beginning, they were unashamedly clamoring that they were developing a fourth-generation fighter, which is fundamentally different from the F-15 and Su-27, as a new generation of fighters. The European Shuangfeng has put forward higher indicators in the design: first, the maneuverability brought by the canard aerodynamic layout is more than that of the old third-generation aircraft with a conventional layout, and the new digital avionics equipment is also more advanced and humane. On top of that, it also has local stealth capabilities.

Relying on these technologies that are far better than the old third-generation aircraft. The Europeans claim that they are developing a fourth-generation fighter, to really talk about it, this European Shuangfeng is indeed better than the old third-generation aircraft, if there is no such thing as F-22, according to the technical indicators of the European Shuangfeng, it can indeed pull a generation difference with the old third-generation aircraft.

The influence of the European twin winds before the F-22 was also quite large, in that crazy late eighties, along with Europe's big moves in the new generation of fighters, even the Soviets were brought into the pit, the most typical is the Soviet Union's MiG-1.44 project, which was also declared by the Soviet Union to be a new generation of fighters, the same canard aerodynamic layout, and the same local stealth design, such an engineering project, it is difficult for you to say that it has not been influenced by the Europeans.

Seeing that the Soviets have been brought in, it seems that the indicators of the new generation of fighters formulated by Europe are about to become universal values, however, the Europeans still undercount the American father's rebellion, and as soon as the American father's F-22 comes out, the so-called fourth-generation fighter in Europe has become a joke. In desperation, the Shuangfeng can only be changed to the positioning of the third-generation and a half-generation fighter.

This is also the origin of the division of three and a half generations of fighters, although it seems sad, because the old Europe is declining in the military aviation industry, and it does not even have the power to assign its own fighters, and it can be seen from here that the old Europe has indeed begun to decline. If old Europe really still has a greater influence, the US imperialists can completely give the European Shuangfeng a step down and classify the Shuangfeng as a fourth-generation aircraft when the fighter is re-designated in the new century, so that the F-22 can be more justifiably described as a fifth-generation aircraft.

If it is really possible to divide the fighters in this way, I believe that this is far more reliable than the new set of five-generation division method that the Yankees themselves came up with for the sake of face, but why didn't the US imperialists do this? The most fundamental reason is that the US imperialists do not want to recognize the cross-generational advantage of the European Shuangfeng over the old third-generation aircraft of the US system, and everything is still because the face of the US imperialists is there. Europe, as a younger brother, is already a great blessing to give you an advantage of half a generation, so don't think of it every day.

The European Shuangfeng is divided into three and a half generations, naturally because it is indeed better than the old third generation aircraft in terms of technical indicators, and the reason why it is better is that these three and a half generations of fighters have begun to pay attention to local stealth design, which is a point that the old third generation aircraft cannot achieve. Now, the republic's new generation of fighter attack aircraft is a product of the same era as the European Shuangfeng, so how can we keep up with the trend of the times, we must also have local stealth capabilities!

"The reason why we want to report separately this time is that our southwest science and industry program has been very different from the plan of other units in terms of design thinking, when other units are still aiming at the old third-generation aircraft of the United States and the Soviet Union, we want to catch up with the goal has become the European joint fighter plan."

In the late eighties, most of the information about the Europa program may not have been disclosed to the public, and it was already a semi-public existence for the counterparts and armies of various countries, and in view of the reasons for the republic's opening up to the outside world in recent years, the Europa United Fighter program has been known to the republic. Now, as soon as they suddenly heard that the goal of the Southwest Science and Industry Program was aimed at the technical level of the European joint fighter, the army and the Science and Technology Commission finally could not continue to be calm.
