Super Weapon Exchange System

What are the weaknesses of the Tomcat fighter?

To be precise, this is not the weakness of the Tomcat fighter, but the common weakness of all pulse Doppler radars.

The working principle of pulse Doppler radar is not complicated. When the radar emits a fixed-frequency pulse wave to scan the air, if the Doppler radar encounters a moving target, there will be a frequency difference between the frequency of the echo and the frequency of the transmitted wave, which is called Doppler frequency.

If it is a fixed target on the ground, then this is a certain value, and it can be eliminated in the radar processing system.

What are the benefits of this?

Before the advent of pulse Doppler radar, ordinary monopulse radars could not detect low-altitude flying targets, because there are so many undulating ground, various buildings, etc., all reflecting radar waves on the radar screen. , It is definitely a snowflake.

Only by filtering out these ground signals can the target be accurately found. In this way, the aircraft that are trying to cover the terrain at ultra-low altitude can be picked out.

This principle is very convoluted. If you have been on a train, when the two trains meet, or on the platform, watching the train enter the station and hearing the train's whistle.

In the distance, the train came all the way, but when it gets closer, the sound will change and become higher. This phenomenon is the Doppler phenomenon. It is because the frequency of the sound changes when the train passes.

After talking for a long time, pulse Doppler radar is very powerful, but it is also flawed and sometimes misses the target. For example, he could not find or attack an enemy aircraft that was flying in the same direction and at the same speed as him. At the same time, he could not attack a target perpendicular to his aircraft. At this time, the target would be the same as a stationary target on the ground. Filtered out.

In this case, you have to switch to PSTT mode, single pulse, without Doppler function, it will not be filtered out.

However, this will take time.

At the same time that Cross in the rear cabin was changing, Chen Rui had already flew out of the cloud group in a fighter plane.

Just now, he was inside the cloud. When the rudimentary radar warning receiver of the MiG 21 found that there was radar wave scanning, he flew out, and at the same time, he flew to the direction perpendicular to the opponent's heading. .

As a result, the other party could not lock Chen Rui.

This is a common tactic in air combat, but it absolutely requires the superb skills of the pilot, because it must be just right to fly vertically. This is completely the instinctive response of the pilot.

However, this also means that the MiG 21 is gradually moving away from the opponent, how can it be close?

Of course, it is a half turn and then fly backwards.

Just like the ancient sailing era, can sailing boats only sail downwind? Of course not. For the experienced old sailors, it is completely possible to grab the wind boat. At this time, the boat is definitely not going against the wind, but by taking a zigzag back and forth route and then going against the wind.

Now, after turning half a circle, the course remains the same, and the course of the opponent is still perpendicular, but the distance is approaching, so flying back and forth repeatedly, forming an S shape, also called a serpentine turn. This technique, In the old hands, that is of great value.

In later generations, some backward planes rely on this kind of maneuver to break through the long-range protective net that the Eagles are proud of, and directly kill them.

Chen Rui is like this now. He made a serpentine turn, and he has successfully reached the opponent's eyes.

If your sword is not long enough, take a step forward! Even in this era, the bayonet in the air is still useful. When your aircraft is not advanced enough, use tactics to make up for it!

Inside the tower, the Yingguo people have gradually become silent from the shock just now. They watched the state on the screen and watched Chen Rui, relying on the spirit of not afraid of death, actually killed Tomcat. Their mood was complicated. .

Up to now, the Tomcat fighters have been suppressed. They have not even had a chance to turn the radar into PSTT state and re-lock it, it is already close!

Even if the Tomcats can lock their opponents in the end, the MiG 21 is still a glorious defeat. In this competition, until now, the Tomcats have not gained the upper hand, and it has already failed.

Han is a terrible country, and their pilots are not afraid of death! At the beginning, in the sky of Goryeo, they were like this. The newly born Han Air Force frightened the navy and air force of the Eagle State.

Such an air force is worthy of admiration.

It is useless to slap other people's flattery. Only when you prove yourself with strong strength can you win the respect of others, just like now.

As for General Zhang, he was already overjoyed.

As long as he was not locked out immediately, Chen Rui would have given the Air Force a face, and now? Chen Rui played around the Eagles.

Just now, the Eagles praised their fighters so smartly. What happened? Can't even beat the MiG 21!

"After you go back, give Chen Ruiji first class!" General Zhang said. This time, Chen Rui definitely made a great contribution.

This is also very beneficial to the next negotiation. How much do you want to sell for your Tomcat with this ability? We can also beat the country with the J7.

"Yes, transfer him to Kong 1 Division." Another general on the scene said.

"Hmph, this good seedling, you still want to grab it, he belongs to our Kong 3rd division."

The air force generals of the Han State were all excited at this time, and fierce battles continued in the sky. Although they could only be seen on the radar screen, the scene was also very exciting.

Two fighters, almost head-on, flew across, what's next?

Of course it was turned. Whoever turns fast can chase behind the other's ass.

Just now, I was bitten by the MiG 21 for a long time. If I can't get it back, it will be too shameful! Now, when the two sides passed by, Brown immediately pulled the rod and kicked the rudder, the wings were fully extended, ready to make a big circle, and quickly turn to the back of the opponent.

At this time, Cross behind, also temporarily gave up operating the radar, but looked out the window. In an instant, he screamed again: "He is climbing!"

That's right, after the two sides crossed over, Chen Rui did not hover horizontally like Brown, but climbed straight up!

Chen Rui turned on the afterburner, and the MiG 21 began to climb lightly.

Seeing this scene, Brown was also anxious at once, he suddenly opened the afterburner, then pulled the operating lever, and then climbed while circling.

But then, there was a sound of vibration from his tail, and when he felt the shaking of the body, he knew that the trouble was serious.

The engine is down again!
