Not to mention the various chain reactions produced by Pakistan after the conflict on the northern border and the Soviet Union, nor the excitement of the southwest science and industry after learning the news.

In the view of Southwest Science and Industry, the battle that occurred in Pakistan was completely expected, and when Pakistan wanted to deploy the Annihilation Sect 7A to the northern border, everyone more or less guessed that there would be friction with the Soviet Union.

Now there are still many things to do in the southwest science and industry, first of all, the J-74 and J-75 jointly developed with the 0611 Institute, the development progress of the two fighters is very fast, and there are many similarities, such as cockpit avionics, air refueling tubes, landing gear improvements, etc.

After the two sides worked overtime to develop these aspects, they were completed half a month ago, and the latter was to do their own things, and Chief Engineer Yu and his technical personnel were making special improvements required by the Navy in accordance with the Navy's research and development standards.

In accordance with the requirements of the navy, the aircraft should be equipped with the C801 air-launched anti-ship missile, which has been developed, to guide naval weapons, and to resist the high-salt and high-corrosive environment at sea

At the same time, the improvement of the J-7 is deepening, and at the same time, presided over by Yang Huihe, coupled with the cooperation of the team sent by Northrop, the new dual fighter developed based on the Northrop YF17 has also entered the early technical scheme design.

"Our large-scale strip wing technology verification aircraft project is divided into two parts, the optimization design of the edge wing airfoil can start now, and the demonstrator uses our current Jianjiao 7A. As for the issue of the telex system, as you said not long ago, we don't understand this thing, and now we can leave it alone and have someone to deal with it. ”

Yang Hui said this very simply. Since you don't know about telex, don't worry about it so much. Honestly do your own big side strip wing technique.

Fortunately, the Americans also understand better, and the Northrop top brass has set the tone. What else? Honestly do what you do, and in the end, if there is a problem, it is also borne by the high-level.

"It's no problem at all, the technical information of our side strip wings is disclosed to each other, and it has been proved that there is no gap in technology between our two sides, and now we only need to partially modify the airfoil according to the Jianjiao 7A aircraft you provide."

Partial modification of the airfoil? Yang Hui smiled, the current Jianjiao 7A fighter is actually a double delta wing aircraft, and it needs to be equipped with large side strip wings. Yang Hui can only say: the airfoil is ready to be redesigned.

As for the template of the airfoil, Yang Hui has long had a plan, and the super seven jointly developed by Chengfei and Grumman in his previous life is a typical side strip wing and trapezoidal wing design. The only difference from the current one is that the shape of the side wing has changed somewhat, but the shape of the main wing can be copied completely.

You don't see the Thunder Dragon fighter of later generations, and when it was developed, it used a large-sided strip wing design, but the main wing has not changed much from the super seven main wing more than ten years ago.

So: "No, no, it's not a partial modification of the wing, in order to more effectively match the large side strip wing design." It is also closer to the aerodynamic shape of the main wing of the YF17, and we decided to completely modify the main wing of the demonstrator aircraft as well, using a cut delta wing with a small sweep angle. ”

The small swept angle cuts the delta wing, the name sounds a bit esoteric and obscure. But as the name suggests, this is a typical trapezoidal wing, which is actually a cut-out delta wing with a small sweep angle.

Yang Hui's proposal is very good. Northrop's team of pneumatic technicians had nothing to say, since the main contractors were willing to modify the airfoils. To better simulate the aerodynamic characteristics of the YF17's wing, Northrop will not object. At most, it's just a little bit of a way to provide Northrop's trapezoidal wing technology.

To be honest, the trapezoidal wing technology really has no technical content, and Northrop is also happy to sell cheap favors, in this red republic attaches great importance to favors, Northrop has now learned this hand.

"Modify the main wing to a trapezoidal wing design, this is also a good plan, we Northrop is naturally quite in favor, and even I can make the decision to provide Northrop's trapezoidal wing technology to you free of charge."

This atmospheric appearance, it really looks like there are some partners between them, Yang Hui nodded with satisfaction when he heard this, people are willing to provide the technology for free, what reason do they have to refuse? If you refuse, it is a crime against the country and the people.

Favors really don't work well in Southwest Science and Industry, especially when it comes to business, there is nothing to talk about in favors, how to do it.

Northrop is willing to come up with trapezoidal wing technology, Yang Hui will not refuse, no matter what, Northrop's technology still has some reference significance, and it is still very good to take a look.

"That's the best, we're going to have a much faster wing design, which is a great benefit for both of us, and I have to thank Northrop for the high winds."

Pretending to be excited, it seems that he has been moved to death by Northrop's small benefits, Yang Hui himself feels that he is pretending to be a little too much, is it really good to deceive our American friends in this way?

Not to mention the rest, Yang Hui got along quite harmoniously with a team of pneumatic engineers sent by Northrop, the atmosphere was very friendly, the sycophants were very well shot, and there was also a small gain: trapezoidal wing technology.

At the same time, 0611 in the southwest of the republic also took action. and Southwest Science and Industry jointly developed the common technology of J-74 and J-75 fighters, and because of the difference in technology in the later period, the 0611 technical team returned to 0611 with technical data.

But another team of technicians has just prepared, bringing together all the 0611 fly-by-wire flight control technicians, and the whole team also has more than a dozen people, ready to support the brother unit.

It is also an aviation scientific research unit in the southwest region, and if the brothers are in need, of course, they must be duty-bound and stick a knife in both sides, even if these people are still working on the key tele-flight control technology of the No. 10 project, they must be dispatched to support it.

Chief Designer Song looked at this team of people, the old and the young still looked quite coordinated, and the fault was not too serious.

"I won't talk about the specifics, everyone has known it for a long time, in a word: for the sake of fraternal units, but also for ourselves, we must not let the Americans look down on us, and remember over there that we are all from the Southwest Airlines of the motherland."

Yang Wei in the team looked at these and silently didn't speak, this should be the second time he went to his old classmate's territory, but he didn't expect that in the entire dormitory back then, Yang Hui is now the most human-looking, and now he is hooking up with the Americans, which is really interesting.

Thinking of Yang Hui, Yang Wei remembered the conversation between Yang Hui and himself when he was still in school, and now both of them are impacting this big difficulty.

"Good boy, I didn't expect you to come out to work in a few years, now I will take one step at a time, step by step, and get the fly-by-wire flight control technology out of the beginning, I can only be a pawn for you this time."

Shaking his head with a smile and leaving with the team, this is a good opportunity to test the development of fly-by-wire flight control for himself, which is really interesting.

At the same time, in the distant Western University of Technology, Yang Wei's graduate tutor, a professor who was responsible for developing the Jianjiao 7A analog fly-by-wire stabilization system, also received the invitation letter and looked excited.

"Li Yun, get ready, we are going on a business trip to an aviation unit in the southwest, this time the opportunity is rare, I think this time I am afraid that the old monsters of various schools will have to pass, we must hurry."

It is after Yang Wei that Li Yun is called, another highly accomplished and talented technical talent in fly-by-wire flight control technology, and what is even more gratifying is that Li Yun has also learned computer software programming technology and is quite proficient.

Learn two technologies at the same time, and be proficient in everything, the last one of Western University of Technology was an undergraduate a few years ago, and it is said that which high-achieving student is now in Southwest Science and Technology (to be continued......
