Soon, Guo Wenchang and the French test pilot got off the plane.

Chief Master Gu and the others eagerly stepped forward to chat with Guo Wenchang to learn about the performance characteristics of the Mirage 2,000 fighter jet. After all, although it was just a test flight, as a professional test pilot, Guo Wenchang can definitely draw many conclusions.<

/p>

At this time, Commander Gu was also scared into a cold sweat, because judging from the experience Guo Wenchang said, the J-8 II fighter was already far behind the Mirage 2,000 fighter before it was designed. No matter how it was improved, the J-8 II

No fighter can be a match for the Mirage Two Thousand Fighters, not even two against one or even three against one.

This also made Commander Gu feel very distressed. He had no choice but to make the J-8 II as powerful as the Mirage Two Thousand. Even if it only reached 70% of the combat performance of the Mirage Two Thousand, it was impossible. After all,

The generation difference is there.

This is just the result of the first test flight experience. There are still many projects that have not been experienced, such as airborne fire control radar and avionics weapon systems.

For Li Shuguang, he had known this for a long time, so he was not that shocked. No matter how the Phantom 2,000 was not good in front of other third-generation aircraft, it was not comparable to the J-8 II fighter.

How can the J-8 II fighter be improved so that it can be compared with the Mirage 2,000 fighter? Li Shuguang thought of the later FC-1 Xiaolong fighter. Isn't it the ultimate improved model of the J-7 fighter?

Of course, the improvement of the Xiaolong fighter can almost be said to be a redesign, and it actually has nothing to do with the J-7 fighter.

After all, in terms of aerodynamic layout, the Xiaolong fighter is no longer the conventional delta-wing layout of the J-7 fighter, but has become a conventional side-wing layout unique to third-generation aircraft, and its maneuverability has made a qualitative leap.

There is also the engine. The Xiaolong fighter uses an advanced medium-thrust turbofan engine, which is not comparable to the old turbojet engine installed on the J-7 fighter.

In addition, there are changes in the avionics weapon system. The Xiaolong fighter jet uses advanced airborne radar and has strong beyond-visual-range air combat capabilities. Later batches even used active phased array firepower.

Control radar, it is not comparable to ordinary third-generation functions.

The onboard weapons of the Xiaolong fighter are also very advanced. The Lightning Ten air-to-air missile is an advanced medium-range air-to-air missile developed by China. Its performance is comparable to the AM120B air-to-air missile. These are more advanced than the Magic missile equipped on the Mirage fighter.

Therefore, in later batches, the combat capability of the Xiaolong fighter surpassed that of the Mirage 2,000 fighter. Of course, because the engine thrust is smaller, the Xiaolong fighter is only inferior to the Mirage 2,000 fighter in terms of mounting capacity.<

/p>

So later, Bati used Xiaolong fighter jets to fight against Asan's Phantom 2,000 fighter jets, often gaining an advantage.

Thinking of this, Li Shuguang knew that the J-8 fighter jet would be comparable to the Mirage 2,000 fighter jet unless it was completely improved like the Xiaolong fighter jet. But from now on, this is unlikely, because in this case it will be the same as the new J-8 fighter jet.

Repeated.

It’s just a difference between a single engine and a twin engine, because the J-10 fighter developed by Chengdu has a canard layout and a large delta wing.

Seeing that Li Shuguang seemed to be thinking about something, General Master Gu asked: "Xiao Li, what are you thinking about?"

Li Shuguang woke up from his thoughts and said quickly: "Ah, I was just thinking about how our J-8 II fighter can get close to the Mirage Two Thousand Fighter!"

Chief Master Gu smiled and said: "Oh, it's a good idea to have such an idea like yours, but it seems impossible at the moment!"

Li Shuguang nodded and said: "Yes, it is impossible at present, but our J-8 II will definitely continue to improve, so it will be possible by then. I think only by analyzing the J-8 fighter's aerodynamic layout, body structure, and aviation

Only by completely redesigning the electrical system can it be possible to compete with the Mirage 2,000 fighter jets."

Chief Engineer Gu said approvingly: "Xiao Li, you are right. You can only start over from scratch. Just like the Mirage 2,000 fighter jet. Isn't it also modified from the Mirage 3 fighter jet?"

Indeed, the Mirage 2000 and Mirage 3 are similar in appearance, both using a tailless delta wing layout, but the difference between the two is still a bit big, especially internally.

First of all, the difference in appearance between the Mirage 2000 and the Mirage 3 is the design of the front windshield and canopy of the cockpit. The Mirage 2000 is a one-piece windshield popular in third-generation aircraft, while the Mirage 3 has a three-piece windshield. Of course, there are also

Above the air duct, the Mirage 2000 has a deflector. At the wing-body connection, the Mirage 2000 adopts a wing-body fusion design, while the Mirage 3 has the same wing-body design as the J-7 and J-8, with the wings directly inserted into the aircraft.

The body is the same.

On the leading edge of the wing, the Phantom 3 has an old-fashioned fixed twisting sawtooth structure, while the Phantom 2000 has a leading edge flap that can deflect downward, which means that the maneuverability is greatly enhanced.

Neither the J-7 or J-8 fighter jets have leading edge flaps.

And the tail nozzle is also very different. The Mirage 3 fighter jet has a tail design of the second-generation aircraft, and the engine is basically wrapped in the fuselage. However, the tail nozzle of the Mirage 2000 fighter jet engine is entirely outside the fuselage.

The internal changes are even greater. The engine of the Mirage 2,000 fighter jet is a generation more advanced and is a turbofan engine, while the Mirage 3 is a turbojet engine, and its thrust is only two-thirds of the Mirage 2,000.

Another one is the avionics weapon system. The Mirage III fighter jets do not have beyond-visual-range air combat capabilities. Only later improved models equipped with Doppler radars have this capability.

Li Shuguang remembered that the J-8 II fighter later had a major improvement model, that is, the J-8 III fighter. Chief Engineer Gu added a pair of small wings to it on the sides of the air intake, so that it became a three-sided wing.

Aerodynamic layout enhances maneuverability.

At the same time, the fuselage has also been shortened by dozens of centimeters, and the engine has been replaced with a turbojet 14 engine. You must know that this turbojet 14 engine, codenamed Kunlun, is a very important model. However, although the indicators of this engine are very advanced, there are some problems.

There were few problems, which also caused the J-8 III fighter to have two major accidents during test flights and was later dismantled.

Kunlun engine is known as the most advanced turbojet engine in the world. Its thrust per unit windward area is the largest among turbojet engines, close to that of turbofan engines.

Unfortunately, this engine did have too many problems. On May 20, 1999, prototype 05 of the J-8 III fighter jet crashed due to a fire in the Kunlun engine during a test flight, which directly led to the end of the J-8 III project.
