Chapter 2443: Primary product

Now, the glass cockpit has become very popular. Various data can be displayed on the lower-view display below, and the pilot can mobilize it when needed. However, these data can only be seen by bowing their heads. In fierce air combat , The pilot must not have that time.
In this way, the advantages of the HUD came out. In the cockpit revolution, the HUD came out first. All kinds of data are projected onto the small piece of glass in front through the CRT. This glass is transparent and does not block the line of sight. I can see all kinds of data needed for flight and battle, and after it comes out, it is very popular.
Even with the development of domestic military aircraft, the original J-7M project started with the modification of the cockpit HUD, and this HUD has also undergone many developments and changes, and there have been technological advances in the fourth generation. On the plane, it finally disappeared.
It is not as easy for pilots to look at this screen as to look at the goggles on their own helmets. If the data is directly superimposed on the goggles, it will naturally be easier!
However, this is not easy!
You know, the current cockpit head-up display is based on the principle of projection. There is a TV-like device below that directly projects the data on the glass of the head-up display. However, if it is the goggles on the helmet, then There must be no equipment to project, it must be the glass that can display it.
If you want a piece of glass to be able to show itself, but also to transmit light, after all, you have to look at the outside world, and the degree of light transmission must be strong enough, otherwise the long-distance targets, those dim targets, may not be seen. In this case, this piece of glass can definitely be done in the world of science fiction.
However, Han Guo's technology has done it. If this glass wants to achieve this effect, there is only one technology, which integrates liquid crystal display devices. This technology is definitely the most advanced in China.
Of course, even relying on domestic technology to develop this kind of equipment is a huge challenge. Up to now, the yield of this kind of device is still very low. To be precise, there is only this helmet at present, the cost of which exceeds Two hundred thousand! This is just a helmet.
However, as the technology matures in the future, the cost will definitely come down. Now, the entire cockpit equipment has also been adjusted, and the program has been updated to be compatible with this system.
"I have tried it on the simulator and it works very well. With this helmet, I am no longer interested in flying other planes." Chen Rui said.
A helmet was bought for Chen Rui. As an excellent pilot, Chen Rui was advancing with the times. Of course he saw the convenience that this helmet brought to air combat.
It can be said that with this helmet, it is more convenient to abuse opponents.
"What data can this helmet display?" Qin Guan asked.
Hearing Qin Guan's question, Chen Rui immediately replied: "There can be various flight parameters, weapon information, external target data, etc., and everything needed for air combat is available, and even the HUD is not needed now. "
Especially when displaying data, the symbols that jumped out on the black glass are really the same as those in the science fiction world.
Qin nodded his head in view: "It seems that it is the most advanced method of the helmet display system."
what? When they heard Qin Guan say this, several other people wanted to jump up and made such a tall device. They thought Qin Guan would be shocked. After all, Qin Guan never proposed this idea. It's all for everyone to think about. While waiting for the turbofan fifteen and the vector nozzle, we have to do something else, update the avionics, that is what we are best at.
Who would have thought that in Qin Guan, it was actually the most primitive?
"If I stepped on it correctly, this will definitely integrate helmet aiming." Qin Guan said.
Song Lao nodded. Since it can be displayed, there is no problem in aiming. Moreover, the most exciting thing is that the pilot’s head is turned, and the crosshair of the helmet display system presses the target, so that the target can be locked. It can be said that it is many times more advanced than that of Xiong Country.
But this also brings a new problem, that is, the helmet must be dedicated to someone. The shape of each person's head is different, the position of the eyes is different, and the position of the pupil is also different. Therefore, each person's head must be measured. , The high cost of making special helmets may have discouraged the Air Force. It is not yet luxurious enough.
"Then, even if it has the most basic functions, it must not be able to display the screen until now?"
"Of course it's impossible, how can it be?" Song Lao said.
If you want this lens to display basic data, it’s not easy to embed those basic liquid crystal cells inside. Now, if you want to display the picture, you have to have all the goggles, and the particles have to be fine. It has to be transparent, which is absolutely impossible.
"Yeah, it's probably choking right now. I can only wait for the future. With the development of our technology, the screen will be displayed. At that time, the field of vision of our pilots will not be blocked by the fuselage."
For pilots, the blind spot of vision is very large. The previous three-piece windshield was like looking out from the small iron windows of a prison. The current bubble cockpit is already very tall and has a wide field of vision, but it is basic Blind spots still exist. For example, you cannot see what is under the wing, which has been blocked.
Qin Guan said that he could not be blocked by the fuselage. Song Lao hasn't reacted yet. Chen Rui has already figured it out: "Brother-in-law, you mean, let's install some cameras on the fuselage?"
Sure enough, young people are still smart. This camera, more than one, a large number of cameras, constitute a distributed synthetic aperture system to achieve an omnidirectional field of view. When the pilot's head is turned, the corresponding images are transmitted, so that the pilot can Like being able to see behind the obstruction, the blind spot can be ignored.
However, this kind of camera is not simple, light, sturdy, and has a high degree of imaging. It depends on the continued development of electronic technology!
If all of these can be achieved, then the current helmet display system is indeed primitive enough, and Song Lao secretly thought in his heart, if you can think about it, if you dare to think, it is definitely not President Qin.
"Of course, these may take ten or twenty years to achieve. We are now able to develop this helmet display system, which is already ahead of the entire era. It is the crystallization of the hard work of our technicians and is worthy of praise." Qin Guan said : "Of course, if we want to use existing technology to continue to make breakthroughs, I think we may have to start with voice input."
