Compared with the original Tomcat fighter, the biggest feature of the J-11 fighter is that it is replaced with a Spey engine. This engine is an authentic second-generation turbofan engine. The thrust-to-weight ratio is not high, but the emphasis is on stability. At the same time, Due to design problems, the altitude is weak. These are congenital defects and cannot be changed.

Now, domestic engine factories are working together to try to build the three generations of engines as much as possible, but this is definitely not a day’s work, even the J-10 fighter must first make do with the Spey engine, leading to the J-10 fighter. There is still a certain gap between its performance 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 frequent surge problems of the original TF30 engine.

Now, after the two F-11 fighters took off, they 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, this is the most commonly used method of Tomcat fighter radar, and now, this F-11 fighter does not use the original AWG-9 radar, but its own imitation model, and Like the original version, due to the radar diameter of up to one meter, the performance of this radar is very powerful. The original AWG-9 has achieved a search distance of more than 300 meters for bombers such as Tu-95.

As for this kind of radar produced by Han Guo, the search distance is also realized. In fact, if the power is increased, the search distance will be increased. However, this is not necessary. The improvement made by Han Guo mainly lies in The processing device in the later stage makes its refresh rate faster and its ability to identify targets stronger. It is useless to deliberately pursue longer distances.

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

The two fighters continued to fly south along the route.

"Unidentified target found!" Not long after the radar was turned on, the screen of the fighter was displayed. Following the shout of the radar officer, Chen Rui immediately felt that his adrenaline was constantly secreted. Here, finally It's here. It's been training, landing, taking off, and it's boring. Now, someone has finally arrived!

Chen Rui was very excited.

"Switch to PDSTT mode." Chen Rui continued to shout.

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

Simply put, it means that when the radar officer sees it, he can shout and find the target!

It only found the target, but there were no other parameters. It was like a flashlight. With a flash, there was a dark shadow in the distance, only knowing that there was, and nothing else.

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

At this time, the radar will change the scanning method and aim all the radar beams at a target. At this time, as the radar waves continue to reflect back, the target's various data are complete.

"The distance is one hundred and five, and the altitude is six thousand." The radar officer shouted immediately after switching modes.

The target has flown 150 kilometers, which is more than 200 kilometers away from the base, not more than 300 kilometers. However, the ground radar at the base did not find the target. What does this show?

It must be a big guy!

Chen Rui's eyes were filled with excitement, and he opened the afterburner without hesitation: "Attention, 192, attention, 192, intercept with me!"

192 is Wang Hongwei's radio code name. Except for the nickname that Chen Rui can call ghosts on the radio, most pilots call numbers.

"192 received." Wang Hongwei shouted.

Fiery flames emerged from the tails of the two F-11 fighters. As the fighters turned on afterburner and accelerated, the variable swept wings also began to sweep backwards. This action was pleasing to the eye.

The most important thing for the imitation of the Tomcat fighter is this variable swept wing. The bear country uses a steel structure, which brings the weight of the system and offsets the advantage of the variable swept wing. The Eagle country uses It is titanium alloy. The welding of this titanium alloy wing box is the most critical, and it is also the technology that Qin Guan spent a lot of effort to finally acquire.

Now, the F-11 fighter is powered on 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 the speed of Mach 2.35, but now, it can only be at a speed of Mach 2. Rush to the airspace where the target appears.

Chen Rui’s eyes were looking sharply into the distance. If it were during the war, he could shoot down the opponent directly with air-to-air missiles at this distance, but now it’s peacetime, so he must fly over. Depending on the observation, even approaching and driving away the opponent’s aircraft.

This kind of task is very dangerous. During this Cold War, the Xiong and the Eagle countries often played such tricks, and Lao Maozi often unexpectedly used impact tactics to directly knock down the target.

Fire in the air will bring a terrible chain reaction, but the impact does not count.

Chen Rui's eyes were sharp. He had seen the reflection of the target 30 kilometers away, and at a distance of fifteen kilometers, he finally recognized the shape of the target.

The target is a large aircraft with a single wing. Based on this feature, the Tu-95 bomber or Tu-95 reconnaissance plane that is the bear countryman can be excluded.

This kind of aircraft is similar to the P-3 anti-submarine aircraft, but it looks larger. There are two turboprop engines on both sides. Could it be that the Eagles are making trouble?

Although they have a good relationship with the Eagles, there is still a trend in the Eagles to boycott the Han. They regard the Hans as a threat. However, the army does not interfere in politics. They only listen to the president.

Closer, closer, Chen Rui finally saw the towering fairings on both sides of the opponent's fuselage. When he saw the fairing, Chen Rui immediately recognized: "The black duck belongs to the bear countryman. Black Duck! Must have taken off from Monkey Country, grandma's, 192, 192, come with me!"

Although Chen Rui has not participated in the first-line battle cruise for a long time, Chen Rui still knows the aviation equipment of various countries in the world, especially the Xiong State, which is still in opposition to his own. Chen Rui knows every type of weapons and equipment.

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