Super Weapon Swap System

Compared with the original male cat fighter, the biggest feature of the J-11 fighter is the replacement of the Spey engine. This engine is a genuine second-generation turbofan engine with low thrust to weight ratio, but the focus is on stability. At the same time, due to problems in design, it leads to high-altitude weakness. These are congenital defects and cannot be changed.

Now, domestic engine manufacturers are making joint efforts to build the three generations of engines as much as possible, but this is definitely not a day's work. Even the J-10 fighters have to make do with the Spey engine first, resulting in a certain gap between the performance of the J-10 fighters and the world's leading level.

Of course, it is also beneficial. The performance of this engine is quite stable and there will be no surge problem of the original tf30 engine.

Now, after taking off, the two J-11 fighters have entered the normal route.

"Attention, turn on the radar, PDS mode." Chen Rui shouted to the radar officer in the rear cabin.

PDS, pulse Doppler search, is the most commonly used method of male cat fighter radar. Now, this J-11 fighter uses not the original awg-9 radar, but its own imitation model. Like the original, due to its radar aperture of up to one meter, the performance of this radar is very strong. The original awg-9, The search distance of more than 300 meters for bombers such as TU-95 is realized.

As for this kind of radar produced by Han country, it also realizes such a search distance. In fact, if the power is increased, the search distance will increase. However, it is not necessary to do so. The improvement made by Han country mainly lies in the post-processing device to make its brush rate faster and its ability to identify targets stronger. It is useless to deliberately pursue a longer distance.

Now, when two fighters turn on the radar together, it is enough to cover a large area of the airspace in front. Under the abnormal radar, this fighter has almost become an out and out early warning aircraft.

The two fighters kept flying south along the route.

"Find an unknown target!" shortly after turning on the radar, there was a display on the fighter's screen. With the cry of the radar officer, Chen Rui immediately felt that his adrenaline was constantly secreted. He came and finally came. He had been training, landing and taking off. He was bored. Now, someone finally came!

Chen Rui is very excited.

"Go to pdstt mode," Chen Rui continued.

Just now, PDS mode was used, which is a state of working in pulse mode and using Doppler effect. At this time, it's just search. The so-called search means that the radar can only obtain the target azimuth information without other parameters.

In short, that is to say, when the radar officer sees it, he can shout and find the target!

It's just to find the target, but there are no other parameters. It's like a flashlight. In a flash, there is a dark shadow in the distance. I only know that there is, and I don't know anything else.

After finding the target, it is necessary to quickly turn to pdstt mode, that is, pulse Doppler single target tracking.

At this time, the radar will change the scanning mode and aim all radar beams at a target. At this time, with the continuous reflection of radar waves, all kinds of data of the target will be complete.

"Distance 150, altitude 6000." the radar officer shouted immediately after changing mode.

The target has flown 150 kilometers, more than 200 kilometers, no more than 300 kilometers from the base. However, the ground radar of the base did not find the target. What does this mean?

It must be a big guy!

Chen Rui opened the afterburner with the light generated by excitement in his eyes: "attention, 192, attention, 192, intercept with me!"

192 is Wang Hongwei's radio code. Except that Chen Rui can call ghost on the radio, most pilots call digital numbers.

"192 copy," Wang Hongwei shouted.

The tails of the two J-11 fighters burst out a blazing flame. As the fighters opened the afterburner and accelerated, the variable swept wings began to sweep back in unison. This action is pleasing to the eyes.

The key to the imitation of the male cat fighter is the variable swept wing. Xiong Guo adopts the steel structure, which brings the weight gain of the system and offsets the advantages of the variable swept wing, while Ying Guo adopts titanium alloy. The welding of the titanium alloy wing box is the most key, and Qin Guan finally got the technology after a lot of effort.

Now, the J-11 fighter opens its afterburner and flies towards the target airspace at high speed. If it is not reluctant to throw away the auxiliary fuel tank, the fighter will soon reach Mach 2.35. Now, it can only rush to the airspace where the target appears at Mach 2.

Chen Rui's eyes are sharp in the distance. If it is in war, he can shoot down the other party with air-to-air missiles at this distance, but now it is peacetime. Therefore, he must fly over, get close, observe visually, and even get close to and expel the other party's aircraft.

This kind of mission is very dangerous. During the cold war, the bear country and the eagle country often played this trick, and Lao maozi was often unexpected, and even used collision tactics to directly hit the target.

Air fire can have a terrible chain reaction, but impact doesn't count.

Chen Rui's eyes were sharp. He saw the reflection of the target 30 kilometers away. At a distance of 15 kilometers, he finally recognized the shape of the target.

The target is a large aircraft with a single wing. From this feature, we can exclude the TU-95 bomber or TU-95 reconnaissance aircraft of Xiong Guoren, and so on.

This kind of aircraft is similar to the P-3 antisubmarine aircraft, but it looks bigger. There are two turboprop engines on both sides. Is it the eagle people who make trouble?

Although we have a good relationship with the eagle people, there is still a trend of resisting the Han Army in the eagle army. They regard the Han Army as a threat. However, the army does not interfere in politics. They only listen to the president.

Closer, closer, Chen Rui finally saw the fairing towering out on both sides of the other party's fuselage. When he saw the fairing, Chen Rui immediately recognized it: "black duck, it's the black duck of Xiong people! It must have taken off from monkey country, grandma's, 192192, come with me!"

Although Chen Rui has not participated in the front-line combat cruise for a long time, Chen Rui still knows the aviation equipment of various countries in the world, especially Xiong Guo, which is still in opposition to his own side. Chen Rui knows every weapon and equipment of Xiong Guo very well.

Therefore, Chen Rui quickly ruled out the judgment of P-3. There is only one possibility, that is, Xiong Guoren's black duck electronic reconnaissance aircraft!
