Commander Huang smiled bitterly and said: "It seems that our J-8I airborne fire control radar has a serious problem!"

Commander Gu nodded and said: "Yes, now our airborne radar, aircraft engines, and avionics weapon systems have seriously restricted the development of our fighter jets. If these problems cannot be solved as soon as possible, I am afraid that our relationship with aviation

The gap between powerful countries will become wider and wider!"

Everyone present felt deeply that aviation technology is developing rapidly now, but in China, because it has been blocked by foreign technology for so many years, it is difficult to make up for the lost time. It is not without efforts by these Chinese aviation people in the coming year.

But it is difficult to rely entirely on oneself. Basic industries have been blocked by others.

Finally, we now have the opportunity to contact the West and introduce advanced foreign technologies. However, the country does not have much money. The most important thing is that everyone knows that the next national defense construction may have to give way to economic construction.

, which means that the funding for the development of weapons and equipment will be even less, and many projects may still face the problem of being cancelled.

Will the improved J-8 model be discontinued? No one can say for sure. For example, if the Mirage 2,000 fighter jet is introduced, then the improved J-8 model or the new domestically produced J-8 fighter may not be available.

Because within the Air Force, there are actually many leaders who are opposed to independent research and development. They believe that money should be spent wisely and directly purchase advanced foreign fighters. Not only is there no risk of failure, but it can also be used quickly.

New equipment forms combat effectiveness.

Independent research and development is too difficult. If it fails in the end, the huge amount of money invested will be wasted. There are too many such things.

Take the J-8 fighter for example. Although its basic model has been finalized and mass-produced, strictly speaking it cannot adapt to the current war environment. It is a very backward fighter. The country has invested so much money.

It took more than ten years, but what we got was a backward fighter. In another sense, it was also a failed project.

The Air Force is not very satisfied with the J-8 fighter. For this reason, Chief General Gu has been banging the table with the leaders of the Air Force, but this cannot solve the problem. Now the J-8 I is still difficult to satisfy the Air Force, let alone the J-8.

Even the J-8 II is difficult to satisfy the Air Force. After all, they are all second-generation aircraft.

Now that the world is dominated by third-generation machines, why are we building so many second-generation machines? Do we serve them as food and drinks for the third-generation machines?

The two chief engineers have said this, and the radar engineers of the 607th Institute are also a little frustrated. Indeed, they also know that the airborne radar developed in the institute has performed very poorly over the years, and even the Air Force does not want to find them anymore.

, I want the 14th Research Institute of the Ministry of Ordnance Industry to develop airborne radar for Air Force fighter planes.

In comparison, the overall strength of the 14th Institute in radar technology is much stronger than that of the 607th Institute of Aviation Industry, but the 14th Institute is mainly engaged in ground radar and sea-based radar.

Qin Tao, chief engineer of the JL7 radar project of the 607th Institute, said very embarrassedly: "I'm sorry, it was our 607th Institute that held back our J-8I project. Our radar does have major problems. We

We will definitely resolve it as soon as possible, please rest assured, two chief engineers."

Chief Master Gu patted Qin Tao on the shoulder and said: "Mr. Qin, we don't mean to blame you. Everyone knows that you have tried your best. This is not a human problem, but caused by various reasons. Our

The foundation of the electronics industry is too weak, there is nothing we can do about it!"

Although these are just words of comfort, Chief Master Gu is obviously helpless.

Seeing this scene, Li Shuguang couldn't help but think that in the next lottery, he hopes to win the airborne radar technology, so that he can help the 607 Institute as soon as possible to solve the problem of airborne radar, not only for annihilation

The airborne radars of the Eight fighter jets, as well as the airborne radars of various aircraft such as the J-H-7, all need to be solved.

Life at the 607th Institute was indeed not easy. In the mid-1960s, the 607th Institute received the task of designing its own airborne interception and targeting radar 204 radar, which of course was for the J-8.

You must know that at that time, the designers of the 607th Institute had no experience with this very backward radar, and they designed and developed it while studying.

At that time, the development of Type 204 radar was also seriously interfered with, so although it was finally developed later, there were many problems.

So the JL7 radar is the same. It is more advanced than the Type 204 radar, but it is also based on it.

Li Shuguang carefully searched for the fly-by-wire flight control system technology he had obtained from the system. Unexpectedly, it also contained some simple records of airborne radar.

Maybe he can help solve the problem. Thinking of this, Li Shuguang asked eagerly: "Comrade Wang Yang, what was the main situation of the airborne radar during the test flight just now!"

Although Wang Yang thought Li Shuguang's question was strange because he was not a radar expert, after all, Li Shuguang was Chief Engineer Gu's right-hand assistant and was now responsible for fly-by-wire flight control, so he still replied: "The radar beam showed normal at first.

But in less than five seconds, the entire screen turned into snowflakes!"

Li Shuguang pondered: "The problem is probably in the circuit. Our electronics industry has a weak foundation, and many parts and components are not up to standard. Now we can only dismantle them and take a look, and maybe we can find the reason!"
p>

Indeed, now the radar can only be dismantled. Seeing that Li Shuguang knows so much about airborne radar, Commander Gu and the others couldn't help but be surprised.

Dismantling work began soon,

After opening the radome, you can see the radar antenna, which looks like a very backward paraboloid, just like the lid of a pot that receives satellite TV.

The flat-plate slot radar antenna would be advanced, but unfortunately the current Chinese electronics industry cannot manufacture it at all. Even if it can design it, it cannot manufacture it.

After disassembling the airborne radar, Li Shuguang discovered the problem. It turned out that there was indeed a problem with the circuit design. When Li Shuguang pointed it out, the radar engineers were shocked. They never thought that such a problem had not been found.

But Li Shuguang found it. Isn’t this a slap in the face?

And the slap in the face hurts a bit, but there is nothing we can do about it. That is the fact. There is indeed a problem with their circuit design.

If we want to change it now, it will indeed take a lot of time and a lot of effort, but isn't that what test flights are like? Sometimes even the whole thing is overturned and redesigned. Now only the circuit part needs to be redesigned, manufactured and installed.
