When the new J-1 project is set in Chengdu, as the big brother of the aviation industry, the 601 Institute and the 112 factory have a sense of frustration, and if the bid fails, they will not have a monetary loss, after all, they are still continuing to produce J-8 fighters, which are enough to support the operation of their factories and research institutes, and will not be like Chengdu There is always a sense of financial tension.

However, the state gave the Tianzi-1 project of the aviation industry, the third-generation aircraft, to the obscure 611 and 132 factories, and they felt frustrated, and this feeling inspired them to be even more angry and look for a breakthrough in their own projects.

This is the J-8 3 project.

They only have the J-8 on hand, and they must tap the potential of this kind of aircraft, replace it with advanced avionics, replace it with high-thrust engines, and replace it with a digital fly-by-wire system, so that this second-generation aircraft can have the performance of a third-generation aircraft, which is their goal.

After all, it's not that difficult, look at the Mirage 2000, isn't it an improvement on the basis of the Mirage 3?

The last time they went to Europe, they bought MBB's digital telex system, and after getting it, they worked day and night to transplant this system to the J-8 fighter and improve the ACT project.

This is definitely the first in the country.

After all, the hardware and software are all done by themselves, the progress of this project is very slow, and the single-axis project still needs time, and the 601 Institute has already made the ACT project in the three-axis direction, and the efficiency is definitely high enough.

Now that they've come up with it, of course everyone has to go over and visit, and they can also learn from it.

As soon as Xiao Yang said this, Qin Feng's eyes suddenly flashed with joy, that's right, if Shenyang came up with active control technology, he really wanted to go over and have a look, and he happened to be with his wife and children again, during this time, he was running back and forth, and he didn't stay with his family properly, as for what to report, when he was in Israel, he had already discussed it with Xiao Yang countless times, all kinds of data, all kinds of flight envelopes, everyone said it very seriously, so now, You can also desert yourself.

"Alright, let's go together." Qin Feng said.

Chengdu is Qin Feng's second hometown, then Shenyang should be Qin Feng's third hometown, in Shenyang, Qin Feng met his lover, and finally got together with her, however, because Qin Feng is relatively busy, he rarely goes to Shenyang later, this time, I don't know how many people will make fun of themselves.

Abducted our daughter-in-law and won't come back, where is there such a son-in-law!

Qin Feng had already been mentally prepared.

Taking the train to the north, the family returned to Shenyang, and when they arrived at home, Gu Tingting's parents were quite happy, and Xiaohutou was also like returning to his hometown, extremely excited, running around the room.

The next day, leaving the child to watch by grandma, Qin Feng and Gu Tingting, as well as other comrades, came to Factory 112.

Many people know Qin Feng, and this time, people keep coming up to talk, from the old comrades who guard the door, all the way to the runway of the factory, they are familiar everywhere.

The people here were very enthusiastic, but Qin Feng was absent-minded, and after a few words, he continued to walk inside until he saw the plane.

This is an old J-8, nose intake, on this kind of aircraft, Qin Feng has been flying for half a year, and he is familiar with everything about it, including the cabin cover that opens forward, and so on.

Mr. Gu and the others were next to the plane, and it seemed that they were preparing for takeoff.

"Hey, Qin Feng, you're here." As soon as Mr. Gu looked up, he saw Qin Feng, and he was going to tease a few words, but Gu Tingting was beside him, so he didn't say anything.

"Yes, Mr. Gu, we are here to learn." Qin Feng said: "This plane is the first one in our country." ”

When he said this, Qin Feng was also looking at the plane, the biggest difference between this plane and the previous plane in terms of appearance was the small duck wing in front of the fuselage, which was a temporary measure to achieve static instability.

The third-generation aircraft was statically unstable when it was designed, and now the modified aircraft was originally statically stable, and by adding a small canard wing in front, the lift center can be advanced, so that this kind of aircraft becomes statically unstable and more sensitive.

This is a seed, this aircraft, the country can also continue to develop more digital fly-by-wire control.

"Lao Gu, you're the first to eat crabs." At this time, Lao Zhou, the person in charge of the development team of the stabilizer who came from the test flight institute, had already come up to greet him.

"This time, we are here to learn from experience, and you have to tell us your experience without reservation, which is a major breakthrough in our aviation industry."

In the face of Zhou Jinhai's request, Gu was always very calm: "Of course there is no problem, the country has spent a lot of money to introduce this system to us, and we just want to digest and absorb it ourselves, now, let me introduce to you this system installed on our fighters, called the 634 flight control system." ”

Mr. Gu was very proud when he said this, although it was introduced from abroad, but in a short period of time, all the staff of the 601 Institute, wearing the stars and the moon, fought day and night, and finally installed this system on their own fighters, and in a short period of time, they had the ability to make the first flight, which is definitely something to be proud of, and this is also a major project for the follow-up improvement of their J-8 fighters.

Originally, it was planned to directly use the J-8-2 fighter, but this kind of fighter is currently steadily being provided to the Air Force, so they can only find a J-8 fighter that was used for test flights before, install the system, and test fly first.

"This system is quite complex, it is a three-axis four-redundancy digital fly-by-wire flight control system, mainly using a four-redundancy microcomputer as a controller, each channel, is a dual-CPU structure, at the same time, it is also equipped with a dual/double-redundancy backup simulation computer, driving eight electro-hydraulic combined servo servos connected with the seven pneumatic control surfaces of the aircraft. As a result, a variety of functions such as aircraft control stabilization, flight boundary limiting, direct force control and autopilot are realized. ”

Which of these projects does not fill the gap in the country? They are already preparing to declare this project to the state as a major technological progress project.

Now, speaking of these, Gu is always very happy, and after speaking, he said to Qin Feng: "We plan to make the first flight in the afternoon, the test pilot of the first flight will be recorded in history, Qin Feng, you are the best test pilot in China, but you haven't been a test pilot of the first flight, do you want to try?" ”
