The new generation of the fourth-generation military large-push turbofan project began to officially promote the development work, and the design of the core machine will naturally take a long time, but fortunately, the current 624 Institute is also quite experienced, and the relevant technologies can all be pre-researched in place, and it will probably be done in about three years when the core machine is developed. Pen, fun, pavilion www. biquge。 info

This conference room is engaged in the chief designer of aircraft design, to say that the person who knows the most about aero engine technology, it is actually Yang Hui, who worked in 0112 ten years ago, at least, this was also the existence of the chief designer of the engine as soon as he entered the design institute, although it is only an engine for model aircraft, but it can be regarded as an engine flying in the sky!

Soon, after Yang Hui said that there was no problem with the engine, new problems followed, and only the familiar voice just now was heard.......

"The head office is taking precautions, since it has started the development of the fourth-generation large-scale push project many years in advance, then our fourth-generation aircraft project should not have too many problems, but we have enough technical research on stealth absorbing coatings in China? Speaking of which, this is the most important technology of the fourth-generation aircraft on the stealth body, 60% of the stealth of the aircraft is achieved by coatings, and the stealth aircraft is largely dependent on this thing to be unscrupulous. ”

Not to mention, although Chief Master Sun did not participate in the aerodynamic exploration of the fourth-generation aircraft, he still has a relatively clear understanding of the key technologies of the fourth-generation aircraft. As far as the sense of responsibility he is showing now, if the southwest side of AVIC gets the heavy four plan in the future, with the various experiences accumulated by Chief Master Sun in the J-18 development project, he will be the chief designer of the naval version of the heavy four on the side of the 0111 Institute in the future, and even the entire project design must be led by him.

There's no way, first of all, before the chief engineer, he didn't even have the chief designer of 18, and then he would have the heart to take this chief engineer of the fourth year? It's not possible! As for the 611 side, it seems that the chief engineer Song over there is not too young, and when the project is established, it will definitely be that the chief engineer Song will not be the chief division, and then the 611 side will definitely be the younger Yang Wei as the chief designer of the heavy four air force type.

As for Wu Binglin, the company's other chief designer who is engaged in carrier-based aircraft, the lightning carrier-based type in his hand is now about to complete the preliminary test work, and the results obtained are also qualified, it is said that this lightning can even be used to block the landing with a small number of bombs, and at most it can land on the deck with two medium-range bombs and two combat bombs.

Chief Wu himself is also leading a team to carry out hundreds of catapult take-off tests at the steam catapult test station built by the Navy, one of which has been packed and shipped to Brazil with technical personnel, and the real carrier-based aircraft carrier take-off and landing test will be carried out in 94, and Northrop and Embraer have also made various preparations in advance.

As long as the lightning carrier-borne ejection and take-off test passes, the task of Chief Wu will be officially completed, and the domestic J-18 two-seat trainer/electric warfare type will also be served by Mr. Wu as the chief designer, and after gradually figuring out the character of the J-18, the carrier-based version of the J-18 can almost be ready to be launched.

The selection of the new generation of chief designers, these are the three generations of aircraft have been completed under the deliberate preparation of the older generation, and almost all of the people who have been mentioned can be regarded as the chief designers of the project, so there is nothing to worry about.

At this time, it is not yet time to choose the chief designer, and the problem faced by everyone at this time is the absorbing paint of stealth aircraft, and if you want to talk about this absorbing paint, it is definitely the United States is at the forefront of the world, which no one can deny, and even the Soviet Union and Europe are playing soy sauce in this regard.

Even after returning to the last place in 2000, it can only be the republic that can claim to be the second in the field of absorbing coatings research in addition to the United States imperialism, after all, there is no fourth-generation stealth aircraft project in Europe, Maozi has a so-called T-50 fighter, but the stealth of the T-50 is also a big joke.

In the design of the entire T-50 fighter, it was not able to be regarded as putting stealth in an important position at all, and there were really few places where the requirements of stealth were really taken into account in the aerodynamics of the aircraft, and when stealth and maneuverability conflicted, Mao Zi was also the first to sacrifice stealth.

The most important thing is that those guys in Sukhoi are still typical of unknowing, all kinds of bragging, saying that they want to use plasma stealth, that funny energy is simply a fight with the third brother, and it is very likely that they were infected by the third brother, but it has always filled the international hooligan club with a joyful atmosphere.

In the last plane, the only country that can wrestle with the United States in stealth coatings, probably only the republic has met the requirements, and the republic of this plane, of course, will not lag behind in radar absorbing coatings, and even the research on this aspect has not worried about AVIC Southwest at all, and the research institute affiliated to the army has carried out research in this area several years ago.

Therefore, if you want to talk about stealth paint, Yang Hui really didn't worry: "Don't worry about stealth paint, this thing has the army's research institute to focus on follow-up, and we don't have to be responsible for this research work. ”

Stealth absorbing paint is definitely a national key top secret, and the sale of the fourth-generation aircraft must be matched with stealth paint, which must be there, but the difference is that like this kind of stealth paint that I honestly climbed the science and technology tree to research, the types of paint that can be obtained in the middle will definitely not be less.

Even the same domestic use of coatings, because of the different environment where the aircraft is stationed, the Navy needs a corrosion-resistant coating, the northwest desert region needs a sand-resistant, high-temperature coating, to the northeast cold region to change to another cold-resistant coating, and this is normal in the early application of stealth coatings, only after 2000 may be possible to develop a better environmental adaptability of coatings.

With a variety of massive types of paints, when sold to the outside world, it is not necessary to take a good look at it, this stealth paint is also a variety of precious, completely consumable items, the relationship between paint and aircraft, roughly like the relationship between printers and ink, when sold not only the price is high, but also the kind of good deal.

It's a pity that this kind of good thing actually made the research institute under the army swallow it early in the morning, and it is not easy for the southwest side of AVIC to grab business with the army, after all, your planes are sold to other people's families, and now you dare to grab business with others?

Among the people who know more clearly about stealth coatings, Yang Hui is not the only one, and the other three fourth-generation aircraft aerodynamic design engineers are also more aware of this problem, and they all nodded and said that they don't have to worry too much about this point, and they can start the design work with confidence.

In the end, after more than a week of discussion, it can be regarded as a preliminary design plan and requirements for the light four within the company, and agreed to the plan proposed by Chief Engineer Lu.

It is also after the collective wisdom of a group of people that another country after the United States has carried out the development of stealth fighters, and even the light four program is directly the world's second stealth fighter officially put into development. (To be continued.) )
