Indeed, the designers present were a little convinced.

They really couldn't create such a design, but they were even more shocked later.

Li Shuguang continued: "In addition to the power system, the aerodynamic layout of our new fighter can also be further optimized, because after using the double beveled inlet, the canards will be installed on the upper edge of the inlet. The edge of the inlet

, will bring about the effect of a side wing, which is better than a simple canard wing. Of course, in this way, the positions of the canard wing and the main wing will change, and they will basically be on the same horizontal line."

"Therefore, the aerodynamic shape has changed from the original, and the coupling effect is different. But overall, the aerodynamic lift effect is higher than before, which can better improve the maneuverability of the fighter. In addition, the wing part also needs to be improved from the current simple

The airfoil is modified to a twisted wing. Although this increases the difficulty of the design, it also brings

The performance improvement will be great. In the design of the external pylon system, it can be increased to nine external pylons, three on the left and three under the wings. Two semi-buried external pylons can be added under the fuselage at the fusion point of the wing body.

With the centerline pylon on the fuselage, there are nine external pylons, which is comparable to that of an F16 fighter jet!"

The semi-embedded pylon mentioned by Li Shuguang is indeed very novel, because it is completely different from the semi-embedded pylon in the middle line of the fuselage of Qiangwujia.

The Qiang Wujia was designed to drop special tactical-level bombs, so the magazine was canceled to meet the needs, and a semi-buried external pylon was designed in the center of the belly to hang the bombs. There was no way around it because the bombs were too big.

, so after the Qiangwujia is loaded with bombs, the bottom of the missile body is very close to the ground, and it is easy to wipe the ground when taking off and landing.

The current new fighter jets have semi-buried external pylons on both sides, which carry over-the-horizon air-to-air missiles. This not only reduces aerodynamic drag, but also has minimal impact on flight performance. After all, the bombs are hung under the wings and are far away from the aircraft.

The farther the vertical axis is, the greater the impact on maneuverability when hanging bombs.

Those photos of Rafale fighter jets that are full of external plug-ins are also staged. After all, with so many external plug-ins, there is no mobility at all.

Because the F16 fighter jet has wing tip pylons, it has a total of nine external pylons. The original new fighter plan did not have this, so there will be two fewer than the F16.

Well now, Li Shuguang designed these two semi-buried external pylons, which can be on par with the F16 fighter jet.

Li Shuguang said: "Of course, if we need to increase the number of missiles, we can also build composite external pylons under the wings, and two missiles can be hung on one external hardpoint. In this case, with three external auxiliary fuel tanks, the new fighter can carry four

With six medium-range missiles and two combat bombs, the range and sustained firepower are guaranteed!"

I have to say that the optimization suggestions proposed by Li Shuguang are indeed very exciting and surprising. Compared with the original plan, it is a comprehensive improvement.

And this is not an unrealistic suggestion, it is completely achievable.

The designers are now fascinated. Li Shuguang continued: "With these external hardpoints, supporting medium-range bombs and combat bombs, our new fighter must also have a good avionics fire control system, so in this regard,

I will mention a new design architecture, which is the integrated avionics system."

Integrated avionics system, many designers are surprised when they hear this term, because it is a new term. Everyone knows that the famous third-generation aircraft in the world, such as F15 and F16 fighter jets, all use centralized and distributed avionics systems.

Electrical architecture.

This architecture was developed on the basis of the original centralized structure. The core is the digital computer, which replaced the original analog computer and formed subsystems and avionics equipment with independent functions. Through the 1553B multi-channel data bus

Cross-link and communicate with central computer.

This is already the most advanced avionics system in the world today. Unexpectedly, Li Shuguang proposed an integrated avionics system. What kind of avionics system is it?

Li Shuguang continued: "The integrated avionics system is a new architecture that needs to be based on digital signal processing technology and image technology, and realizes the sensor signals and sensor signals of each avionics subsystem through the sharing of radio frequency components and antenna calibers.

Highly comprehensive processing of data. The reason why this avionics architecture is proposed is because we are already lagging behind others. To catch up, we must focus on the future.

If we still develop the same avionics system as the F16, then by the time our new fighters enter service, it will already be the 1990s. By then, the Americans may have developed an integrated avionics system, and there will be improved models of those third-generation aircraft.

We may use a more advanced integrated avionics system, which will put us at a disadvantage. Therefore, I think it is necessary to develop and install an integrated avionics system on the new fighter!!"

There was a burst of warm applause. This time, the designers expressed their sincere respect for the avionics system proposed by Li Shuguang.

No matter whether it can be done or not, at least someone can come up with such a good idea, which is something that no one can think of.

Whether it is the fly-by-wire flight control system, the cockpit display system, or the weapons management system, they are all subsystems of the integrated avionics system.

So next, Li Shuguang simply explained the avionics system architecture he designed to everyone. In fact, Li Shuguang is not sure that he can help the 611 Institute develop a comprehensive avionics system, but he has a system, and he will definitely be able to do so by then.

After obtaining this set of technology, he has only obtained part of it, but it has far surpassed the avionics system designers of the 611 Institute.

When Li Shuguang finished speaking about his optimization suggestions, General Tu could not help but applaud and stood up and said: "Comrade Li Shuguang, listening to your lecture is better than working for twenty years. Your suggestions today are very special."

Well, I think with these optimizations, the new fighter project must belong to Chengdu Aircraft and 611."

Isn't it? This is too advanced. Compared with the J-13 designs of Shenfei and 601, it is simply not a product of the same era.

The J-13 fighter is designed to imitate the American F16 fighter. It looks more like the F16 in terms of appearance. However, the J-13 design is a low-end and cheap third-generation fighter. It may not meet the standards of a third-generation fighter in some places.< /p>

Its main technical indicators are similar to those of the F16 fighter jet. It adopts the aerodynamic layout of a side wing with leading edge maneuverable flaps and the same abdominal pitot tube inlet.

The J-13 fighter jet was originally planned to use the Spey Mk.202 military turbofan engine, but its performance was naturally lagging behind.
