Regarding the J20, a fighter jet, many military fans will say they know a lot about it, whether it’s the aerodynamic exterior or the built-in bomb bay, there’s a lot of information to see the details. But in fact very little has appeared about the most secret place of the J20, that is, the internal situation of the cockpit, and there are many unknown parts of this warplane.
For example, this time in the public media, appeared in a J20 twin formation takeoff footage, in the cockpit of the pilot’s helmet on the gauges, making people feel very strange, whether this is a head display or a derivative screen display?
In this video, we can see that as the J20 takes off, on the pilot’s helmet, there is always something like a dashboard floating on the helmet, and it seems to be active, constantly moving around in the helmet’s indication, not only on the goggles, but also on the metal part of the helmet, which makes many military fans very puzzled.
And for this case, we have to first determine that this activity should be an instrument displaying flight data, and there are two possible sources, one is the instrument data inside the helmet display, and the other is the projection from the flight-derived screen display. So further analyzing these two possibilities, some speculate that this is instrument data from inside the head display, and we’re seeing it from the outside? The fact that the meter data was found to be positive rather than mirroring the opposite means that the data couldn’t have been the head display data in the helmet, otherwise it would have been the opposite mirror image. And more importantly, the display inside the headgear is not visible from the outside.
What’s more, this helmet and the last J20 propaganda used in the hand-adjusted goggles is the same, should not be a fly helmet with head display function, the black part is only goggles only. In fact, even if now has been changed to helmet display, also may not be able to see, you know the general media program report military equipment, the quoted video content may even be 1 year ago.
Having ruled out the first possibility, the most likely one comes from the diffraction screen, which is configured on many third-generation fighter jets, and is therefore normal on the J-20. The diffraction screen is actually a wide-angle holographic projection that gives the screen a larger field of view, especially for night flying, so it’s possible that the diffraction screen’s instrument content can be projected onto the helmet. What we see is actually the image captured by the cockpit recorder, which is precisely the angle at which the diffraction screen’s instruments are projected onto the helmet and captured by the recorder. This may be the reason why the instruments seem to be “alive” and keep beating on the helmet.
In fact, I believe that many military fans are also seeing this scene for the first time, and the J20 is such an advanced stealth fighter, in fact, despite the fact that it has been exposed to the public eye, there are still quite a lot of advanced aspects that are unknown to the public. In fact, this is rather a good thing, after all, the strength of the weaponry needs to be publicized, which is self-confidence as well as enhanced deterrence. But in addition to propaganda should also have their own killer mace, although the diffraction screen display is not a high-tech, but the J20 PL-15 and powerful phased array radar are actually hidden killer mace.
Overall, most of what is seen now is still the same scenes from the J20’s earlier cockpit, and the new J20 helmet should now be a new helmet with AR capabilities that can have fuselage perspective interaction. The most obvious change in the appearance of the new helmet compared to the old helmet is the smoothness above the head and the very large size of the goggle section, which is clearly evident in the comparison. Therefore, J20 is still improving every subsystem even after it has been launched, and the combat capability is still improving, so the future J20B and J20S are more worth looking forward to!
