If I could get him, wouldn't there be more hope for the New Fight? But now Commander Song also knows that it is almost impossible to snatch Li Shuguang away. How could Commander Gu let him go? They are also old rivals.

.

But even if not, it would be good to listen to this young man’s views on the J-7 modification or the new J-7.

Mr. Song thought about it and asked: "Xiao Li, what do you think of our improved J-7? Is there any hope?"

Li Shuguang thought for a while and said: "Mr. Song, do you want to hear the truth, or do you want to be polite?"

Mr. Song chuckled and said: "Of course you have to listen to the truth. It doesn't matter if it doesn't sound good!"

Li Shuguang smiled and said: "Okay, then I will boldly express my opinion. I think any improved model of our J-7 fighter is too conservative, and the performance improvement will not be particularly large. If we really want to change it, I will

I think it is necessary to make major changes, complete changes, especially the nose air intake, which must be changed!"

Song Wencong nodded and said, "Okay, keep talking!"

Li Shuguang said boldly: "I heard that the current J-7 II fighter will introduce foreign radar avionics. In fact, our 607 Research Institute can do this now. Marconi's ranging radar is not advanced. We

The J-8 II will all use pulse Doppler radar. Do you think it is too outdated to change the J-8 II to use a ranging radar?"

Song Wencong smiled and said: "That seems to be the case. Can you tell me how to change it?"

Li Shuguang said: "Then let me tell you the truth, I think our J-7 fighter can change the air intake from the nose to the belly air intake, similar to the F16 fighter, but the design of the air inlet naturally cannot be used in the F16

Pitot tube type air inlet requires a knot

I have a preliminary design for a supersonic air inlet with a simpler structure, which is to use a bulge to replace the surrounding partitions and other structures. This will not only greatly reduce the weight, but will also be very good for the development of stealth aircraft in the future.

Of!"

Song Wencong was a little surprised and said: "You are talking about the air intake duct without a boundary structure. This is not realistic, so how can the air intake volume be controlled?"

Li Shuguang said with a smile: "So this is just a preliminary idea of ​​mine. Using a bulge should be able to meet the air intake requirements within a certain range. Of course, if you are still pursuing high altitude and high speed, let's not mention it. In this way, the air intake of the nose can be improved.

After injecting air into the abdomen, a medium-caliber fire control radar can be installed. I think that in this way, the J-7 modification can be close to the radar detection range of the F16 fighter jet, achieve the capability of beyond-visual-range air combat, and also have the ability to attack the ground."

Song Wencong said: "Then this improvement is indeed big enough, but what about other than these?"

Li Shuguang said: "Of course the avionics system also needs to be modified. You can also use a relatively low-priced dual-redundancy fly-by-wire flight control system. It is only a single-axis system. The cost will not increase too much, but the flight quality will be greatly improved.

, of course this also needs to be accompanied by modifications to the aerodynamic layout.

, the wing is changed from a large delta wing to a double delta wing, which can greatly improve the subsonic maneuverability and increase the external plug-in capability. Of course, it would be better if the engine can be changed. Use a more advanced medium-thrust turbofan engine. This is a small aircraft.

F16!"

After listening to Li Shuguang's views, everyone smiled bitterly, because these technologies are too advanced and impossible to achieve in the current aviation industry.

Song Wencong said: "Xiao Li, your idea is very good, but do you need to know what our aviation industry is like now? With so many advanced technologies, if we really want to develop them, we will not improve the J-7, but follow them.

The new Jian is the same."

Li Shuguang smiled and said: "Mr. Song, this one is still incomparable with the New J-Fighter. It should be positioned as a low-end second and a half generation fighter, or a light quasi-third generation fighter. I think such a fighter is not only our

The navy and air force are in great need of it, and foreign countries equipped with a large number of J-7 and MiG-21 fighter jets are also in great need. If they are exported by then, they will definitely be very popular!"

The idea proposed by Li Shuguang was actually the J-7 MF fighter developed by Chengdu Aircraft in the late 1990s in his previous life.

At the Zhuhai Air Show in 2000, the appearance of the J-7 MF caused a sensation at the entire air show. It can be regarded as the ultimate improved model of the MiG-21. As for the later FC1 fighter, it can no longer be said to be a modification of the J-7.

It is a truly new third-generation machine.

But it is a pity that the J-7 MF arrived too late at that time. After all, with the FC1 fighter, foreign customers no longer looked down on the J-7 MF fighter, and the domestic air force would not want such a lightweight second-generation and a half fighter.

, because the J-10 will soon be put into service, there are Su-27 fighter jets that have been introduced and made locally.

But in the 1980s and early 1990s, if the J-7 MF fighter was produced, it would definitely be very popular.

Song Wencong said: "Xiao Li, do you think we can really come up with such an advanced J-7 modification? Even if I believe your suggestion, it's hard for my superiors to believe it. Without a formal project, nothing can be done!"

Li Shuguang smiled and said: "Mr. Song, I think as long as you are willing, you will have no problem impressing the superiors with your prestige and eloquence. Only in this way can our J-7 reform truly satisfy the military and satisfy foreign customers."

, Otherwise, if we continue to toss the backward J-7, I personally think it really doesn’t make much sense. After all, if the J-7 does not make major changes, it will be difficult to adapt to the future battlefield environment. The more equipment, the greater the losses!

”

I have to say that Commander Song was a little tempted by what Li Shuguang said. He was really too conservative before, but there was nothing he could do about it. Since this young man could improve the airway of the J-8 II and fly by telex,

I also have a pulse Doppler radar, so can you help me with the J-7 modification?

Song Wencong looked at the young man with expectant eyes: "Comrade Li Shuguang, if you can help me, I think I can give it a try!"

Li Shuguang said excitedly: "Mr. Song, are you serious?"

Song Wencong nodded and said: "Of course I am serious. Why don't I want to make our J-7 fighter better? Now that the J-8 II has become so good, the J-7 reform cannot be too lagging behind!"

A deputy chief engineer of the 607th Institute said: "Then let's not consider introducing Marconi's radar avionics?"

Song Wencong said: "No, we still have to talk now, but we have to be prepared for both. Comrade Li Shuguang can help us design a miniaturized pulse Doppler radar, so we don't need Marconi's!"

Li Shuguang patted his chest confidently and said: "Mr. Song, don't worry. I'll help our 607 Institute handle the radar issue. You just need to get the military to agree to the new J-7 reform project!"
Chapter completed!
