J-20 As the first fifth-generation stealth fighter independently developed by my country, the J-20’s equipment is in service. It not only fills the gap in the field of fifth-generation stealth fighters in my country, but more importantly, the J-20’s equipment is in service and also improves our country’s air defense strength. significantly improved.
Since the J-20 was put into service in batches in 2017, although officials have disclosed many details of the J-20 more than once or twice, the internal details of the aircraft's cockpit and the world's first rotating and everted combat bomb bay have never been disclosed. Never really made it public. So although the J-20 has been in service for many years, what does the inside of the cockpit look like? What are the internal details of the combat bomb bay? The outside world can only "speculate" by referring to similar models or official reports through some other channels.
However, recently, as the J-20 batch equipment entered service for five years, officials also disclosed many details about the J-20’s cockpit and combat bomb bay for the first time.
1. Advanced cockpit:
Since the J-20 has been put into service in batches, although the outside world has analyzed the positioning of the J-20 and the achievements of my country's advanced avionics system, it is boldly speculated that the cockpit of the J-20 should have long abandoned the three-piece cockpit of F22 The small-size monochrome display screen is initially the same as the American F35 stealth fighter , which uses a single or two large-size full-color LCD displays. In addition to being able to display more parameters and status at the same time, such a larger display screen has a better display effect than a small display screen, allowing pilots to see real-time data more intuitively and make timely decisions. Carry out corresponding maneuvers and flight.
But speculation is still speculation, and doubts have never been absent. When the outside world was speculating on the internal layout of the J-20 cockpit, there was already a certain view on the Internet that the American F35 cockpit uses a single 21-inch full-color LCD screen because the F35 directly cancels the holographic diffraction system, so there is Larger space and more needs set up a larger full-color display .
However, the J-20 still retains the holographic diffraction system, so it is unlikely that it will use a single large-size display. In addition to the fact that once a single display fails, it will not be as reliable as a dual display. The existence of the J-20's holographic diffraction system will also occupy a larger internal space, which in turn will make the size of the single display screen installed inside it not too large.
Indeed, in terms of reliability, once a single display screen fails, the entire system display interface cannot interact with the pilot in real time. Unlike dual displays, the probability of simultaneous failure is very low. Even if one fails, the other can still display in real time without affecting normal flight.
However, judging from the official information released this time, the J-20 cockpit does not use dual display screens, but uses a whole large-size display screen. Its size is much larger than the 21 inches of the American F35. According to the J-20 20's cabin interior space, the size of this large-size display is at least about 25 inches. At the same time, there are no separate buttons around the display, which means that it is likely to use touch and voice control modes, plus a larger The display screen not only displays better effects, but also displays more parameters at the same time, which is more conducive for pilots to observe the flight status and other parameter changes of the fighter aircraft in real time.
And in previous official reports, it was also disclosed that in addition to the large-size full-color display screen in the J-20 cockpit, it also benefits from the use of side stick control mode, so the pilot also has a separate tablet computer between his legs. A slightly larger display screen, this medium-sized display screen not only makes it easier for pilots to observe data changes during super-maneuvering flight, it can also serve as a backup for the large-sized display screen at special times.
And it is rumored that the 25-inch large-size display screen equipped on the J-20 was specially customized by Suzhou Changfeng Electronics, a subsidiary of AVIC, for the J-20 and other stealth fighters. In addition to being the largest among all current fighters, It is also the lightest, highest resolution and most integrated display among the large-size LCD screens equipped on global fighter aircraft.
Internal details of the combat bomb bay:
When the J-20 is officially put into service, although the official has taken the initiative to disclose many details of the J-20's combat bomb bay, judging from the previously officially announced combat bomb bay details, basically only the details can be seen In order to increase the target search range of the PL-10E infrared combat bomb, the J-20 cleverly adopts a rotating and everted missile pylon design. This way, when the J-20 and the enemy aircraft enter into close combat, the infrared combat bomb can be extended in advance. Outside the bomb bay, the door can still be closed, which will not increase wind resistance and destroy the stealth effect.
However, judging from the recent official details, thanks to the larger body size of the J-20 itself, although its combat bomb bay currently only carries one PL-10E infrared combat bomb on one side, the one-sided The internal space of the fighting bomb bay can be clearly seen to be very large.
Moreover, the design of the J-20's rotating and outward-turning rotating missile pylon is very advantageous. Its rotating arm is very long, but at this stage, only one missile launch pylon is installed, and this size and space can completely set up three missile launchers at the same time. A missile pylon can be installed on the upper side of the existing missile pylon. Another missile pylon can also be set side by side. In addition, the rotating pylon and the bomb bay door can also be designed to extend the warhead position like the F22. "Tilted missile launch mode" with the tail still inside.
In this way, the single-side combat bomb bay can mount 3 Thunderbolt 10E infrared combat bombs at the same time. A J-20 stealth fighter can attack 6 enemy fighters at the same time, or launch two bombs to at least shoot them down with a greater chance of winning. 3 or more enemy aircraft. Of course, the combat bomb bay of the J-20 is so radically set up. However, with the larger main bomb bay space of the larger fuselage, it can also mount at least 6 PL-15 ultra-long-range air-to-air missiles at the same time, or at least Mounting 24 small-diameter guided bombs is not a problem.
