If the competition between the three design units of the four major projects in China is a test of the system integration capabilities of the three units, then for the development and procurement of various subsystems, this is another picture, at least in terms of avionics system, AVIC Southwest has always been the most advanced in China, and there is no one. Pen @ fun @ pavilion wWw. ｂｉｑUｇE。 ｉｎｆｏ

It is no exaggeration to say that now the Republic of China dares to say that the best in avionics equipment technology is only, and it can only be AVIC Southwest, and the integration of the whole system of the heavy four still needs to compete, but in the design of the avionics subsystem is a project without too much suspense, and now the whole republic can do the avionics of the fourth generation aircraft, and can only be a professional avionics equipment manufacturing company led by Liyun.

Only the team led by Li Yun can complete a complete set of systems in China, at least they have been able to complete the Jewel Pillar avionics system similar to the early use of the F-22 fighter before this, and it can also be installed with J-18, so it is already the top in China in terms of ability and technology accumulation.

Yang Hui must have left Li Yun on the side after the meeting, and the two came to the small conference room next to them one after another, and then quietly talked about the most important avionics system design of the heavy four.

"Let's talk about the design first, after all, our 0111 plan and 611 plan are scheduled to use the avionics you provide, so the design of this set of avionics must be good enough, you can roughly talk about the design ideas, or there are better cockpit layout renderings, I would like to have a sneak peek."

If you want to look at the avionics design of the cockpit, of course, this can be, this avionics design has been issued a pre-research project a long time ago, and the avionics design is far less than the design cycle of the whole fighter design, and as long as the early technical architecture can be completed, the renderings can be made.

After sitting down, Li Yun handed over a confidential floppy disk that he carried with him, which contained general introductory information, and when Yang Hui opened this picture with curiosity and excitement, it was really .....

The first picture is just a rendering of the renderings, but the information to be expressed in this picture is absolutely eye-catching, at least the avionics design of the cockpit of this heavy four is compared with the J-18, there must be a new breakthrough, first of all, the display design of the flat three times was abandoned, and it is this flat and three down design, but it is the early standard design of the F-22 combat cockpit.

Yang Hui is very interested in this design scheme, in his opinion, this is simply the F-22 avionics transition to the F-35 stage of the two-in-one, after the adoption of such a design, the development risk of the project will definitely be well controlled, and this is an excellent fighter in the avionics design, can achieve a good balance between performance and technical risks.

After carefully reviewing the design of this avionics, the first thing to do is to give an affirmation: "This is indeed a lot of ideas!" Just this flat design, especially this large LCD monitor, is simply a stroke of genius, but I think there should be no way to make such a large military LCD screen in China now."

If you want to create a qualified military-grade large LCD display, this is still a bit of a challenge, at least in the J-18 era, there are only three small LCD displays, and that has been done after considerable efforts and investment, as for the current domestic technology to directly make F-35 kind of large military-grade LCD display, of course, there are still some difficulties to break through.

However, after Yang Hui raised the question just now, judging from Li Yun's reaction, this guy should have an idea about solving this large LCD monitor, otherwise he wouldn't have been indifferent after Yang Hui raised the question, it was obviously confident!

It wasn't until Yang Hui continued to look at another textual introduction that this guy was finally eye-opening, it turned out that the avionics design of the 90s could still be played like this, it was just 6 flying!

The ears also sounded at the right time: "Mr. Yang, you are absolutely not mistaken, in fact, the large LCD display seen in the renderings is not a single piece, but is spliced by two medium-sized LCD monitors, but we have the technical ability to achieve the "seamless splicing" of these two displays, and after a special algorithm synthesis, the two monitors can be combined to display a large dynamic image, so this is the rendering that I saw before. ”

The use of two LCD screens spliced together, in order to display large image technology, which in the last plane of 2000 is also a more mainstream new generation of military fighter display technology, such benefits can naturally effectively reduce the cost of avionics, and ensure that the display has a certain margin of tolerance, even if one of the displays is broken, there is another piece can continue to be used, so that the whole display system will not lie down immediately.

Of course, as far as the cockpit avionics designed for the heavy four are concerned, in fact, in terms of the loss tolerance rate alone, this is definitely very high, after all, the heavy four avionics design brought by Li Yun this time is not just two medium-sized screens connected into one large screen.

This is based on the technical level of the 90s and the first few years of 2000, after a comprehensive evaluation, it was decided to keep the other three down-looking displays, but these three down-looking displays are even smaller than the down-looking displays of the J-18, probably less than 7 inches.

There is already a large display that occupies the most valuable space,The placement of the other three displays is a little particular,The left and right two must be placed horizontally below the large splicing display,Probably a little above the pilot's knee,But because it is placed horizontally,Plus this is a serious heavy fighter,The cockpit space is also quite large,It can also be placed。

The display in the middle is naturally placed vertically on the central axis, that is, it is often used to place the center joystick in front of the place, and this also belongs to the bottom of the large screen, as long as the head is lowered slightly, it can still ensure that the pilot can see and operate the display in a timely and clear manner.

As for what to do with the original central joystick, there is no way, in order to ensure that there is enough space in the cockpit to place a flat four monitors, the flight control stick is helplessly placed on the side of the pilot, that is to say, the turtle finally used the legendary tall side stick.

As for who is good between the center joystick and the side joystick, it's really not good to talk about it, it can only be said that both have their own benefits, and now the heavy four need to free up the place where the joystick was placed in the past, so it must be the use of the side lever as it happens, anyway, the impact is not too great.

Therefore, when Yang Hui now sees the avionics design of the cockpit of the heavy four, he has only one idea from the beginning to the present: that is, this display screen is really damn much, and when the pilot wants to see what he wants, we are really not short of that screen resource, and we are absolutely awesome in terms of situational perception and data monitoring.

Of course, the most satisfying must be because these three 7-inch small displays use tall pressure sensing technology, that is, the touch screen technology of our later generations, but in the nineties, if you want to ensure reliability and achieve a 7-inch large screen, it must only be a monochrome display, and the so-called color touch screen is definitely impossible.

But even so, it's enough to make this heavy four-cockpit design taller, and that guy is so awesome that he has no friends. (To be continued.) )
