Super Weapon Exchange System

The Eagles are too big.

In the flight show just now, they calculated it. In fact, their engines are not powerful, and the thrust-to-weight ratio of the whole machine in combat is only 0.7. However, the Eagles only filled 1 ton of fuel for the flight show. For a Tomcat fighter that can load six tons of internal fuel, this is almost a good fuel.

When the air show was over, the engines were all turned off, that was all the fuel had been consumed, and this kind of action was simply and neat.

If they fill up the fuel, they will definitely not be able to do that kind of action, because their engine is not powerful, and the Tomcat fighter has been dragged down by the Tf30 engine.

And now, it is to confront the exercise.

Perhaps, for the Eagles, this flight confrontation is not a confrontation at all, it is just flying over, finding the target, locking it, and then returning.

In this case, 1 ton of fuel is more than enough. Now, their body may be filled with more fuel, but it is impossible to exceed 2 tons at most.

In this case, Chen Rui is given a chance. Even if Chen Rui does not show up, he will just hold them back. As long as they are not found, Chen Rui can be invincible. The Eagles will have to be due to lack of fuel. And had to return.

Isn't it silly if a soldier goes to the battlefield without enough ammunition and food?

Qin Guan had already begun to feel more confident. As for the scholars and Xiang Jing behind Qin Guan, they were not even worried.

Qin Guan wants to make tricks, who can prevent them?

Others don't know, Xiucai and Xiang Jing know it. It is normal to tease others with Qin Guan's methods.

However, Qin Guan hadn't really thought about it that way.

The exercise airspace is too far away. Even Qin Guan’s mental point scanning system cannot scan hundreds of kilometers at will. If this scan continues, how many mental points must exist?

Even if it can scan, the processor can’t keep up. That’s right, now Qin Guan has felt more and more that this thing in his brain is almost the same as a computer, or it’s upgraded from time to time and crashed. Now, The processor performance is certainly not powerful enough.

Chen Rui has disappeared from Qin Guan's mental point scanning system, and now the two energetic Eagle pilots have also taken off.

"Prepare to turn on the radar, PDS mode." At this moment, as soon as he flew up, Brown said calmly to the radar officer behind.

For an airborne radar, many military fans care about the detection range. They think that the farther they are, the more powerful they are. In fact, of course this is not the case. For any radar, you must first pay attention to its working mode.

Talking about detection distance out of the working mode is to be rogue. There are many working modes of AWG-9, among which the most commonly used is PDS (PulseDopplerScan) mode: pulse Doppler search.

As the name suggests, this is a search mode that works in pulse mode while using the Doppler effect.

As a search, AWG-9 can only obtain the target position information, but no other parameters. In short, in one sentence, it is used to see if there is a target in the 65-degree airspace ahead, nothing more; even if the target is found, Unable to launch an attack.

In this mode, its detection range is the farthest.

How far is it?

In the introduction to Han, the terrible detection range of this radar of more than 300 kilometers is such a model.

Of course, it is also related to its detection target. The detection effect at this distance refers to a large bomber like Tu-95.

For a small and flexible fighter such as the MiG-21, the detection effect is lower.

Even if it is low, it can detect about 200 kilometers, and the planned confrontation airspace is only 200 kilometers away.

So, as long as they fly together, they can find the target, and then they can catch up, change to lock mode, and lock each other!

It's easy. This is the advantage of generation difference.

Brown at the front is very relaxed, and Cross at the back also began to operate the complex AWG-9 radar.

The reason for the need for two-seaters is that the operation of this radar is very complicated, and only a dedicated radar officer can be competent, especially when guiding the Phoenix missile, which requires dedicated manpower.

A bright line circled the screen, but nothing appeared.

"No target was found." Cross said.

not found?

Hearing the answer from his companion, Brown was still very confident at this time. He pushed the lever and slightly changed the position of the nose.

Because the Doppler mode is used, if the target and itself are flying vertically, the angle between the two tracks is 90 degrees. At this time, the radar will filter the target as clutter.

Just push the nose of the aircraft a little to change the direction, and at the same time, as the fighter flies forward, the distance is constantly decreasing.

I can definitely find it.

Cross opened his eyes wide and continued to observe on the radar screen.

(This radar screen is a common name, and its scientific name is a 25.4cm diameter cathode ray tube tactical information display.)

The screen is very clear, and you can see a shining light spot. It is a civil airliner. The transponder has automatically answered it. At the same time, there is also a civil aviation route. They fly in this airspace every day. Familiar.

And apart from that civil airliner, there is no other target, on the sea?

Impossible, your radar has already turned on the Doppler mode, and it can be detected in clutter even on the sea.

"PS mode, you must find it!" At this time, Brown was already a little anxious.

Can not find the target, that is the most terrible, which means that oneself will be attacked at any time!

PS mode, (PulseScan): Pulse search, this mode removes the Doppler effect and only works in a state of pulse mode.

In this state, most airborne radars have, and even some of the only functions of backward radars.

It is also a search. It can only obtain the target position information without other parameters. At the same time, the detection range is greatly reduced, which is about a discount to PDS.

However, it has an advantage. It avoids some blind spots of the PDS mode, such as the target at the same direction and the same speed, the target across the track, etc. If you can't find it in the PDS mode, then try this mode!

The PS mode is used to fill the blinds of the PDS, now they must find the target!

Following Brown's order, Cross quickly adjusted the radar and switched to PS mode. He looked at the radar screen expectantly, hoping to find out.

However, he was disappointed. What about the goal? The other party won't get lost anymore, flew to another place, right?
