Qin Feng has found a new direction since then, although it is only a pneumatic layout, which is the first step in the development of fighters, but Qin Feng is already quite yearning.

Because, this is the biggest shortcoming in China, and it is a much-needed fourth-generation stealth aircraft!

"The best canard wings are used on enemy fighter planes." Qin Feng said to Song Lao: "Americans really like to fool people." ”

The United States has fooled people too much, complaining to the whole world that aircraft carriers are useless, and it is enough to develop light aircraft carriers, and in the future, when it comes to the battlefield, it will be a live target, and as a result, the aircraft carriers of various countries have been fooled and lame, and the Americans, the aircraft carriers they have built themselves, but they are larger than the other, and now they have reached the level of 100,000 tons, and the Star Wars program during the Cold War period is even more fooling people, and the Soviet Union has not been fooled as a result, and the United States has not studied those so-called space warships at all.

Now, Americans have always claimed that the duck layout is the worst kind of layout scheme, but if you look at the development trend in the world, they are all engaged in the duck layout.

In Europe's canard layout, there are three brothers, and it can be said that in addition to the United States, other countries are engaged in a duck layout.

"Yes, for the United States, they have studied the canard layout many times, but they have powerful engines, so they don't care about the advantages of the canard layout, their engines are enough to propel aircraft with a conventional layout, so they went down this old path."

If you have a strong engine, will you use the canard layout? Maybe the conventional layout will also be used, but this can only be thought about, now, the turbofan ten has not yet been finalized, the turbofan fifteen is even more gone, Song Lao must be based on reality, then only the duck layout, can still get a good performance under this condition.

"Yes, in terms of engines, we are the weakest, but our aerodynamic layout is advanced enough, and we can make up for this regret from the aerodynamic layout." Qin Feng said.

Lack of power, pneumatic to make up, can only be this choice, and their own research on the duck layout is also handy, the key is to link it with stealth.

Stealth, in fact, was the first invention of the Soviets, they found the radar reflection formula, but they held on to what plasma stealth technology, and finally fell behind, and the Americans came step by step, and they have come to the point of going against the sky.

The stealth fighter of the Americans, has already been created.

Of course, we will not lag behind, and we are exploring new technical solutions step by step.

Now it is the stage of the study of prototypes, aerodynamic layouts.

The whole aircraft adopts a canard layout, and the nose is somewhat similar to the F-22, with a diamond-shaped nose and air intakes below both sides, however, above the air intakes, canard wings have been added, but behind the canard wings, there are side strips, which is simply to bring in all aviation technology.

The entire rear fuselage looks quite flat, so that the fuselage will become a lifting body, and it is very similar to the Su-27, compared with the current J-10, the layout is very different, which is also the result of many considerations, for example, the fourth-generation aircraft should have a built-in bomb bay, in this way, the fuselage is bound to be elongated, twin-engine heavy aircraft, of course, to give full play to the advantages of the wide fuselage, the fuselage has a good lift coefficient, which is quite a good design.

Absorbing the strengths of all families, and finally blending together, this requires a fairly high foundation, and only a powerful person like Song Lao can do it, first explore the design of the wind tunnel, it will take several years, so, when it really turns into detailed design, you can only wait for the descendants, at that time, Yang Gong will definitely be able to pick it up.

Qin Feng's theoretical research on the wind tunnel is not very clear, and in the past few years, he has also learned a lot of knowledge from Song Lao, and the appearance of the new fighter is maturing little by little.

"There are a lot of rudder surfaces for control, which is a test for our flight control system." Qin Feng said that with the continuous research, there are more and more pneumatic rudder surfaces, and it must be very difficult to control.

"Yes, it must be a test, but you have to trust our technicians, it is absolutely no problem to engage in this flight control." Song Lao said, he is quite relieved, with Yang Gong here, the flight control is absolutely no problem!

Anyway, there is no need for Song Lao to care, what Song Lao has to do is the integration of pneumatic and stealth technology, and explore the most advanced layout scheme, as for how to design the interior, it is not for Song Lao to consider.

There are still many new technologies to be explored inside, the built-in bomb bay, the missile is in it, how to launch it is still a problem, these are all things that need to be explored in the future.

"Yes, Yang Gong is really amazing, now, the two-seater type of the J-10 has been finalized, and the Thunder Dragon has also completed the test flight, these projects are too fast."

Who would have thought that Yang Gong would do a good job of these projects in just a few years, it is unbelievable, in recent years, the development of domestic military aircraft has been quite rapid, and the motherland's aviation industry has progressed quite rapidly.

"Yes, if you want to say that the most pleasing thing is the early warning aircraft, this kind of fighting machine, we finally got it." Song Lao said that when it came to this project, all the aviation people were holding their breath, and they were originally going to be imported, but they were stuck by the United States, that is, they were not exported, and the country worked hard to make it strong, and within a few years, it was developed and successfully finalized.

"If it weren't for the restrictions on the Il-76 large transport aircraft platform, we wouldn't be able to get more early warning aircraft, and the current early warning aircraft will definitely be able to form a brigade, but we have already completed this process and accumulated a lot of experience, so the early warning aircraft using the Y-8 aircraft as a platform is also in full swing in research and development." Qin Feng said that when it came to this project, he was naturally very happy.

In the future, under the guidance of our Air Police 2000, this new type of stealth aircraft will fight in the sky, and that kind of scene is the most desirable.

It's a pity that the platform is not enough, so we began to study medium-sized early warning aircraft, after all, the only one that can be produced in China now is Yun-8.

This is also thanks to the rapid development of electronic technology over the years, almost a few years, the performance will be doubled, and the volume and weight will be reduced, otherwise, it is really impossible to place all kinds of electronic equipment in a body platform like Yunba.

Qin Xue has been busy all these years, and the last time she was in a video chat on the Internet, Qin Feng felt a little distressed when she saw that her sister was thinner.

For the development of avionics in the motherland, my sister has dedicated half her life, and I hope to be able to retire from the front line like myself in the future and enjoy myself.
