Why does the J-20’s helmet keep changing?

The J-20 fighter jet is my country's most advanced fighter jet. According to Russian standards, the J-20 fighter jet is a fifth-generation fighter jet. Advanced fighter jets are advanced in every aspect, including the pilot's helmet. Some people say why the pilot helmets of the J-20 aircraft always change. This is because each batch of fighter jets is different and they are always testing new scientific research results. It's like installing a computer. I've configured the host. I'll change the keyboard today and the mouse tomorrow. Is it weird?

Pilots have certain blind spots when flying. Ordinary helmets cannot meet the requirements of pilots to process multi-angle and multi-directional information at the same time. Therefore, there is an urgent need for new helmets. The J-20’s helmet display system and F The structure of the -35's second-generation helmet display system is relatively similar. The optical display system (transparent) and the shading lens (dark) are independent of each other. The pilot lifting the shading lens does not affect the normal operation of the optical display system. In the first-generation helmet display system of the F-35, the display system and the visor were integrated. If the pilot wanted to lift the visor, he had to turn off the display system, which greatly affected actual use. Therefore, the first-generation flight helmet was quickly eliminated. . Judging from this detail, the J-20's flight helmet is already relatively mature. After all, you are crossing the river by feeling the stones of Eagle Sauce, so you can avoid many detours.

The J-20 helmets currently exposed mainly include the following types:

The TK-31 helmet used by the J-20 in 1990 did not have fly eyes, but it had HMDS function . Images can be projected directly onto a screen on the helmet's visor, similar to an AR display. This helmet has accompanied the J-20 through the initial test flight stage. Another HMDS helmet for the J-20 that appeared in "Lijian". J-20 VR helmet.

The helmet is actually a combination of a 360° panoramic VR display and a helmet. The numb toad spots on the helmet are motion capture devices in movie motion capture technology. This technology is used to capture the pilot's head movements and transmit them to the visual sensors on the body. The real-time images from the sensors are then synchronized back to the glass goggle display of the pilot's helmet.

At first, the appearance of the J-20 helmet was similar to that of an ordinary flight helmet, but soon after, a new flight helmet appeared with a large number of bulges on the back of the head. At this time, they have reached the highest level in the world.

Integrate, summarize and process the collected radar, infrared, data link and other information, and the large-capacity data can be easily fed back to the pilot. Previously, human-computer interaction was mainly accomplished through heads-up displays and cockpit displays. Now, it's directly reflected in the pilot's multifunctional helmet.

The J-20’s fuselage is covered with a large number of sensors, which improves battlefield information perception capabilities. The flight helmet allows the pilot to see the entire airspace surrounding the fighter, greatly improving the pilot's vision. Without looking down at the monitor, the pilot will automatically point to the seeker of the missile he sees without having to pre-load the missile's combat capabilities. parameters, and then unlock the complex and cumbersome launch procedures, which greatly improves the overall air combat capability of the J-20.
