Of course, the avionics display design of this flat four is not the original design of Liyun, at least at this time, the Yankees used a flat and four design scheme on the Super Tomcat fighter F-14E/F, so it is still possible to find a "father". Pen @ fun @ pavilion wWw. ｂｉｑUｇE。 ｉｎｆｏ

However, F-14E/F is not a large display made of two medium LCD splicing, this guy is directly made of a large LCD monitor, which can only be said to have a strong technical foundation is awesome, and our Republic still can't compare!

However, the use of a whole display has the benefits of a whole display, but the two-in-one splicing scheme also has its own unique advantages, which is like the debate between the side lever and the center joystick, no one can complain about where the other design is not good enough, it can only be said that the difference in industrial technology and design ideas is caused.

The introduction of the touch screen into the fighter display is definitely a unique original design, which can effectively improve the ergonomics of the cockpit, and enhance the sense of forced grid and science fiction, which makes people really feel unclear.

"The design of this cockpit is very good! It seems that it is right to let you do this heavy four avionics design before, but what I want to know most now is that in this avionics design scheme, is there a corresponding improvement in the helmet display and aiming system, and the head display we used on the J-18 is no longer enough to ensure technical advantages, how to solve this? ”

The avionics system is also very extensive, after all, the full name is called the avionics system, as long as you are electronic equipment, even the airborne radar can be counted as part of the avionics system in a broad sense, under the scope of such a division, it is not wrong to count the headset and head sight into the avionics system.

It's just that this time Yang Hui thought of the beginning, but didn't think of the end, especially when Li Yun explained the situation, it made people feel even more embarrassed, it turned out that the situation was made like this.....

This is also an expression of sudden realization: "I see, this means that the avionics system of the fourth year also adopts the subsystem subcontracting model, but this is okay, at least it can concentrate the best design and resources from the whole country, and listen to you, I also think that Hongdu's requirements are indeed right, just do it according to their requirements!" ”

In fact, the situation is not complicated, mainly because the most authoritative in China in this headset and head-aiming is definitely not AVIC Northeast, nor is it the avionics system company led by Li Yun, but as early as the eighties, it has been exposed to the headset, and the introduction of technology Hong is the best in related technology.

I think that when Hongdu cooperated with the Italian Markey company, when the two sides jointly improved the strong five, the technology used included the helmet display technology, but later due to various reasons, the improvement of the strong five was not continued, but with the establishment of the Southwest Science and Industry J-18 project at that time, Hongdu's head-mounted display technology was finally reborn on the J-18 project.

That is to say, the earliest contact in China, the earliest to carry out the independent development of related technology is to belong to the Hongdu side, after the collapse of the Soviet Union, and from the Soviet Union to carry out further head aiming technology, so that after the integration, there is the idea of upgrading the headset used in the J-18 avionics system to the head sight.

There can be such an idea, it is because it was decided that the avionics system used by the light four was improved from the avionics system of the J-18, and the avionics of the J-18 did not have the ability to aim at the helmet, it only had a certain helmet display ability, and this is just right for a multi-purpose fighter, as long as it can display the data that everyone needs.

Until the time of the Hongdu Light Four project, the helmet display used on the J-18 is definitely not enough, after all, this is a fourth-generation fighter that needs to be exported in positioning, and also has strong anti-air combat capabilities, to say that there is no helmet aiming system, it will definitely not work.

The new generation of fourth-generation aircraft must be used with a new generation of large off-axis close-range combat bombs, and the large off-axis combat bombs must be combined with head sights to really play a role, which is why we must talk about the requirements put forward by Hongdu before: the helmet aiming system they developed for the heavy four should not only be provided for the use of the heavy four, but also be able to provide them with their own development of the light four for use, and allow export.

If it is really for AVIC Southwest, the helmet aiming system is not a device that needs to be banned from export, even if it is the avionics equipment used on the heavy four, but if you want to say that the export will be exported, anyway, it uses the old generation avionics architecture used by the old J-18, and it is a generation behind in the overall design architecture, then no matter how advanced your subsystem is, it does not make much sense to not be able to exert all its combat capabilities.

As a professional avionics designer, Li Yun knows no less about the benefits and disadvantages than Yang Hui: "That's right, I also think that I can agree to Hongdu's request, anyway, the avionics architecture of the light four is our old generation of gem pillar design, and it doesn't hurt to use the latest head aiming system for it, at least we now have the latest improvement ideas and breakthroughs for the old generation of gem pillar avionics system architecture design." However, we still have two biggest problems to overcome: the complete operating system of airborne avionics and the new generation of airborne computers. ”

For the two biggest problems raised by Li Yun, one of them is directly related to the most critical operating system in the avionics system, you must know that the operating system used by the aerospace vehicle is not to install Microsoft's question and death system can be used, but must be specially designed for the special use requirements of this kind of avionics equipment.

As an embedded operating system, the on-board operating system of the fighter pursues real-time, stability and security. Internationally, it is mainly represented by the VXWORKS system of the American Wind River Company, which is widely used in the fields of communications, military and aerospace, and is used in manned combat aircraft such as F-16, F-18 and B-2, X-47 UAV and various missiles and space probes.

Even the on-board operating systems used by several fighter jets before AVIC Southwest are also pirated American Wind River products, including the 10th and J-18, and this method can only be applied to the time when the Republic's avionics design capability has not yet been fully expanded, but as far as the current heavy four projects are concerned, it is absolutely necessary to put an end to the continued use of American operating systems.

It is time to solve this problem, which is related to the development and maturity of the aerospace industry chain of the entire AVIC Southwest and even the entire Republic.

"The operating system of this fighter avionics is extremely important, and we didn't have the ability and time to solve this problem before, that's one thing, we won't say too much. But now! In my opinion, the airborne avionics operating system project of this aircraft should be set up separately as a research project, and the head office will allocate a part of it, and then you will raise some funds yourself, and I will also submit an application to the high-level of the Science and Technology Commission to see if it can be made into a key project, after all, this system is not only for combat use, but also for other types of transport aircraft, missiles, and even aerospace systems, which is a very valuable project.
