Super Weapon Exchange System

The radar did not find anything, neither at high altitude nor at low altitude. Brown's eyes looked outside. In this airspace, there seemed to be nothing.

"The pasqueflower called the tower, and the pasqueflower called the tower. No target was found. Maybe the opponent is not in the drill area."

Hearing this sound, the entire tower was also strange, and there was also nothing on their radar screen.

After the opponent takes off, it is flying at ultra-low altitude. That is definitely to avoid being detected by radar. But now, if the opponent is not in the exercise area, it can almost be determined that you are winning. You can't even find the exercise area. The technology is too bad, right?

At this time, on the base's radar screen, the flight of the civil aviation airliner was gradually approaching the pasque-flower fighter.

what happened?

The Han National Air Force is also suspicious. Just now, Chen Rui went up in a huff. After going up, where did he hide?

Many people think that the sky is quite clear, and there is a radar to search for the target. It seems that you can't hide it at all. However, for a skilled pilot, just like a sniper, learn to use various conditions to camouflage himself.

Like now.

Qin Guan had already guessed something, there was a smile on his face.

The Air Force Commander General Zhang turned his head and glanced at Qin Guan. Qin Guan nodded calmly at him, so General Zhang guessed something.

Yes, although we are not as well equipped as humans, our pilots are always the best in technology. Our pilots also have their own set.

During the confrontation exercise, the base can only make judgments. Now, the pasqueflowers can’t find the target. Ordinarily, it can be determined that the pasqueflowers have won. But now, they are all in doubt. If they win in this way, it would be too simple. ?

Could it be that the civil airliner is weird?

Brown was in the sky, relying on his eyesight, to quickly search. At this time, in the sky, the passenger plane was flying head-on, in the direction of the sun's rays. He put down his goggles and looked at the four-engine The large passenger plane is flying over his head.

This kind of aircraft is the common Boeing 707, nothing special.

and many more!

At this time, the opponent's flight altitude and speed were right, so white trajectories were drawn in the sky.

In the clear sky, you can see that when a jet plane is flying at high altitude, one or several long "white smoke" will appear behind the fuselage, commonly known as "aircraft smoke."

Of course, in addition to performance, jet aircraft will not emit smoke casually. This is a special cloud system formed by condensation of water vapor after the exhaust gas discharged from the aircraft is mixed with the surrounding air. It is called in aviation flight circles and aviation meteorology. Aircraft wake.

According to the causes, airplane wakes can be divided into exhaust wakes, aerodynamic wakes and convective wakes. The exhaust gas trail can be divided into exhaust gas condensation trail and exhaust gas evaporation trail. The most common is exhaust gas contrails,

When an airplane is flying, a large amount of fuel is consumed, and the water vapor and part of the heat generated are discharged out of the airplane body with the exhaust gas, enters the atmosphere, and rapidly mixes with the surrounding air to form a contrail.

Not all mixed gases will condense, which depends on the temperature, humidity and atmospheric pressure of the ambient air itself. When an airplane wakes, the air temperature is mostly between minus 41 degrees Celsius and 60 degrees Celsius.

For civil aviation, it doesn't matter if there is such a trail, but for fighter jets, it should be avoided as much as possible.

What if it is a combination of fighter jets and civil aviation airliners?

A Boeing 707, four engines, in the air, there will be four wakes, these four wakes will overlap in the backward diffusion to become a wide wake, but now, there are five wakes!

That's right, it is five wakes, combined together, one of the wakes is obviously lower than the four of them.

What does this show?

Below the passenger plane, there is a small plane, because the other party flies too close, so only one target can be displayed on the radar screen!

On the AWG-9 radar, the resolution is quite high. If a target is displayed on this radar, it means that the other party is almost flying against the belly of the passenger plane!

That's right, Chen Rui did just that.

When Chen Rui knew that he couldn't win by relying on his own small plane, he could only use the surrounding environment to conceal himself. Otherwise, he would be locked by radar when he could not get close to the opponent at all.

How to use it?

Either it is pasted on the sea surface and integrated with the waves on the sea surface, but it may still be detected by high-precision radar using the Doppler effect.

So, just after he flew in, when he saw the smoke of the passenger plane in the distance, he immediately had an idea.

Move up!

At this time, his flight had left the search range of the base radar, he was tightly attached to the passenger plane, and when he flew back again, the base radar could not find him.

Compared with the Boeing 707, the MiG-21 is quite compact. Its tall vertical tail is almost next to the belly of a civil airliner, flying in the sky of 10,000 meters.

This requires extremely sophisticated technology. The MiG 21 is hydraulically controlled. As long as the hand shakes a little, the vertical tail of the MiG 21 may cut the belly of the Boeing 707.

However, Chen Rui was strolling leisurely. Although he did not fly the MiG 21, the J-7 flew a lot. The flight quality of the two is almost the same, and both require the skill of the controller.

Now, under the belly of the Boeing 707, he saw the Tomcat fighter in the airspace below and knew that the other party was looking for him. Now, the opportunity has come!

Chen Rui pushed the joystick and got off the Boeing 707. Goodbye, babysitter!

The MiG-21 is small and flexible, and now Chen Rui, with the help of the Boeing 707, has gone around behind the Tomcat fighter.

When the MiG 21 detached from under the belly of the Boeing 707, the radar wave reflected by it was also displayed on the base radar.

Inside the tower, a radar operator shouted in surprise: "The passenger plane separated a target, the MiG 21! God, he was hiding under the passenger plane!"

Suddenly, people nearby looked at the radar screen one after another, looking at the small bright spot, which was flying towards the Tomcat's back in a swift posture, like a tiger descending a mountain.

"Trust our friends, now we will treat the confrontation drills in the sky fairly." Qin Guan's voice is loud. Although the eagle language is not particularly fluent, he still allows others to hear clearly. Hey, if you want to If you remind the pilots in the sky, cheating is too shameless, right?
