The design of camber double vertical tail has been regarded as a relatively mature one in the technology accumulation of Southwest Science and Industry, at least it has been used in the stereotyped military aircraft, and this alone has surpassed the research of many units on this aerodynamic design. However, this time the Southwest Science and Industry Plan has not only worked the vertical tail, but also attracted everyone's attention to the design of the huge side strip wing.

"This aircraft seems to be very distinctive in the design of the side strip wing, in terms of the shape of the strip, it is obviously larger than the side strip wing used in the Fengtian program, I seem to have seen the Southwest Science and Industry in the domestic scientific research journal has introduced this design, they say it is called the Gothic large side strip wing."

To say that the technological progress of Southwest Science and Industry in recent years has actually been made public to a large extent, especially this kind of technology jointly developed with Northrop, there is naturally no need to keep it secret. In this era of increasing transparency, it is possible to keep a project completely secret, but the huge amount of money required is completely disproportionate to the benefits.

These costs are quite expensive, although the big side wing technology is good, but there is no need to do absolute confidentiality of the entire project, the best way is to have limited confidentiality, that is: the core technical parameters, data to keep confidential is enough, as for what pneumatic shape, obvious aerodynamic advantages and disadvantages of these are simply public.

As a result, there has been a technological blowout of Southwest Science and Industry over the years, and there are constantly a variety of bright and blind technologies to be developed and semi-public, and the semi-disclosure of these technologies has not only enhanced the reputation of Southwest Science and Industry. At the same time, it can also give great encouragement to scientific researchers.

Think of a researcher who has worked so hard to develop a technology that cannot be disclosed because of a confidentiality requirement. This is definitely a very big blow to scientific researchers, after all, normal scientific researchers are human beings. It is normal to love fame, and I hope to show off my research technology in order to win the respect of my peers, which is what most researchers are looking forward to.

In this case, it is not surprising that the big side wing technology is known to some people who like to read books and pay attention to details, at this time, the two people in the audience can talk about the advantages and disadvantages of the big side strip wing technology, the main reason is that Southwest Science and Industry has more or less some simple technical disclosures before.

"Yes, this thing is the big edge wing technology of Southwest Science and Industry, and the news they released said that this is a technology jointly researched with Northrop. Judging from Northrop's rigorous style in technology, I think that this large edge wing technology is indeed as advertised by Southwest Science and Industry. I even heard that the JF-17 lightning fighter under development in Southwest Science and Industry has adopted this technology, and I have to say that this Southwest Science and Industry has surpassed Fengtian a lot in terms of conventional layout aerodynamic technology. ”

I just said it well, but I didn't expect to pull Fengtian out and hack it again in a blink of an eye, which is really quite sad. But then again, the F-16 small side wing technology used in Fengtian's plan is indeed behind the large side wing technology of Southwest Science and Industry. And this is not good news for Fengtiansuo, as long as everyone can see that the faces of the bidders in Fengtiansuo this time are not very good-looking, it seems that there will be a good show to watch later.

Everyone looked at the model brought by Southwest Science and Industry this time. But there are not many people who understand the essence of the Southwest Science and Industry Program, DSI air intake has not been made public at this time, at most some people are puzzled by this somewhat strange air inlet bulge, and the heart of the Southwest Science and Industry Program has added some mystery.

With the largest 1:10 model in place, the smaller 1:100 model was sent to the table of the main review leaders of the Science and Technology Commission and the army. The preliminary preparations have all been done, and the same slide production, Southwest Science and Technology Industry pays more attention to publicity. I used professional drawing software to make several sets of rendering pictures of the whole machine, and showed good results through slides.

Look at the shape of that fighter on the screen. Looking at the model on the stage that was a full circle larger than the other units, the other competing units had to say, 'I'm convinced'. In the past, I only knew how the Southwest Science and Industry was so bullish and how good the technology was, but now I finally saw the strength of the Southwest Science and Industry through the details.

"Lao Ding, you see how the southwest science and industry plan is, it also adopts a conventional pneumatic layout, but it seems to be more than a little stronger than Fengtian in terms of pneumatic choice! Especially this inlet bulge, it's the first time I've seen this kind of thing, and I don't know if it's as evil as they advertise. ”

Commander Liu's side was the first to hold back the doubts in his heart, if it is said that the camber double vertical tail and large side strip wing technology is the housekeeping skill of Southwest Science and Industry, and the army still has some understanding of these things, then the DSI air intake brought by Southwest Science and Industry this time is a real mysterious design, and Commander Liu is not surprised by this.

"I don't know much about this, when the Southwest Science and Industry to the Science and Technology Commission reported to the Science and Technology Commission, it only said that it was going to jointly develop a new air inlet design with Northrop, in view of the good cooperation experience between the Southwest Science and Industry and Northrop, we did not pay too much attention to the Science and Technology Commission, but who knows that it has only been more than a year or two years, and the Southwest Science and Industry has come up with this kind of thing, anyway, I am now surprised by this kind of thing, I hope this little bulge is really as good as this information says."

The relationship between the Southwest Science and Industry and the Science and Technology Commission is good, and the relationship with the Navy is quite iron, but this does not mean that the Southwest Science and Industry can also maintain a good relationship with the Ministry of Aviation Industry.

Slightly pouted his head, and at the same time pursed his mouth: "I think this Southwest Science and Technology is neat what is the so-called DSI inlet is meaningless, if you can solve the trouble that you have to work hard to solve before through a small bulge, then other companies need to bother to study what air intake, even if the 611 brings the double oblique cut wave intake, it is still only a substantial improvement on the traditional two-dimensional rectangular air intake, such a technological progress, It was all done after a lot of trouble, and now where did a southwest science and technology industry have the ability to make this kind of thing. ”

For the Ministry of Aviation Industry will say this kind of thing, the Science and Technology Commission, the army is not the slightest strange, those problems between the Southwest Science and Industry and the Ministry of Aviation Industry have long been semi-open, as long as it is within the system, relevant units, and even some gossip people who are more concerned about the aviation industry know, naturally at this time will not say much, the army, the Science and Technology Commission need to do strong competition within the aviation industry, rather than a monopoly of the martial arts alliance system.

Just when the Ministry of Aviation Industry is still unsatisfied, the Southwest Science and Industry has finally begun the program demonstration, Mr. Li has long been familiar with the program, and before coming to the Southwest Science and Industry internal decision-making level conducted a simulation report, all aspects can be said to be ready.

"Like the previous Fengtian Institute, this time our Southwest Science and Industry brought the plan is also the use of conventional aerodynamic layout, but our conventional aerodynamic layout has adopted a lot of quite cutting-edge technology, in this program you can see the camber double vertical tail technology used by the American F-18 fighter, as well as the large edge wing design that has not even been used by any finalized fighter, and it can also be seen" (to be continued.) )
