Everyone is no stranger to talking about screen central controls. Many cars are now equipped with large-screen central controls. Even if they don’t, many friends will replace them with large-screen central controls when purchasing. It is comfortable in one word. So, military fans, have you ever heard about the large-screen central control in the cockpit of the J-20? I believe that even military fans who are familiar with the J-20 may not know much about this part. Although the J-20 has been on its first flight for 11 years, and there have been many detailed reports in recent years, its internal avionics equipment is still relatively mysterious. Recently, the large touch screen used in the J-20 cockpit was unveiled, with a size of 25 inches. It is the most advanced airborne screen currently on active fighter aircraft, far exceeding the level of similar Western models.
According to social media reports, we have seen the same type of onboard integrated display system used by the J-20. Judging from the picture, there is a large rectangular display on the entire cockpit panel, which comprehensively displays the aircraft status, electronic point map, ammunition status and electronic instruments. The system carried by the J-20 is produced by AVIC Suzhou Changfeng Electronics. It has a 25-inch touch screen display with a resolution of 2560×1600. For the small fighter cockpit, this is undoubtedly impressive. Called "huge".
The same type of screen system used by the J-20 has actually been unveiled many times at air shows this year. According to reports, the display screen installed in the J-20 cockpit not only functions as a "central control" but is also the terminal of the integrated combat system. Various data processed by the fighter's central computer will be directly displayed on the screen, and The entire screen space can be flexibly divided according to different task modes to display the most important driving data for the driver. For example, when flying at supersonic speeds in and rushing on the road in , the speed, fuel volume and arrival time can be displayed. During visual range air combat, more areas can be divided to display radar sensing data, ammunition conditions, etc.
It is worth mentioning that under the 25-inch main screen, there is also an ordinary flat-panel-sized multi-function display . The rest of the instrument equipment are also LCD displays, which have completely replaced the so-called " One level and three down” (head-up display, fire control, radar, electronic map, etc.). It can be said that this is also a reflection of the completely different levels of fourth-generation aircraft compared to third-generation aircraft. Of course, some military fans will ask, is this LCD screen stable? After all, when we usually use the touch screen of our mobile phones, there will be no response, poor contact, etc. Do we need traditional instruments to be blocked in an emergency? According to data, this kind of LCD display has high reliability, so the J-20 has canceled all backup mechanical instrument equipment and is a completely electronic and modern fighter jet.
In comparison, the LCD display level of the J-20 is also better than that of Western fighters of the same type. Among the stealth fighters, the American F22 and F35, as well as the Russian 57, the F22, which was developed earlier, uses an 8-inch LCD. The more advanced F35 only uses a 21-inch monitor with a resolution of 2560×1024, which is lower than the resolution of the J-20 screen. Although the screen area of the Su 57 is larger, it is made up of two more than 10-inch screens, which is slightly inferior in terms of system complexity and stability, and the flexibility of screen division is also required. Drop some.
Judging from the previous pictures of the F35 cockpit, this type of touch screen seems to have a problem, that is, it will leave a lot of fingerprints on it after being out and about for a long time. It is speculated that this may be left by the rough surface of the flight gloves. Many netizens are also worried that it is a pity that such a good touch screen does not have a film. They just don’t know where to apply it. Moreover, it will be very troublesome to apply it to a 25-inch screen. If there are bubbles, obsessive-compulsive disorder may be very painful.
Generally speaking, the reason why the J-20 is advanced is not simply because of its excellent aerodynamic appearance, but because each subsystem has reached the world's advanced level, ranging from the simulation of a screw to the avionics system telex equipment. If Unless the overall domestic technical level has improved significantly in the past ten years or so, it would be difficult to achieve a systematic breakthrough like the J-20.It can be said that the J-20 is the crystallization of countless hard work and sweat. The breakthrough of each subsystem may have an arduous journey. I also have deep respect for the domestic military workers.
