171 Night low altitude penetration defense

At 7:30 p.m. on that day, Chen Fei and his teammates got into the fighter plane on time and completed all the preparations.

"Call the Yangtze River, the dragon is ready, request to take off!" Chen Fei said in the channel.

"The runway has been cleared, the dragon can take off!" The voice of the tower commander came from the channel.

Hearing the affirmative command, Chen Fei slowly pushed the throttle lever, then loosened the brakes, glided, turned, and went on the runway.

Because it was night, the night was very rich and it was pitch black everywhere, and only the lights on the track could provide guidance for everyone's running, so everyone was very careful.

Of course, the members of the Shenlong Squadron have become familiar with the night take-off and landing. Everyone is not afraid of the night take-off and landing under complex weather conditions, not to mention that the weather conditions are very good tonight, so although everyone is careful, they are actually quite relaxed.

"Dragon, you can take off!" The voice of the tower commander rang in the channel.

Chen Fei was the first to slid, so he answered after hearing the command, and then began to push the throttle valve. He directly pushed the throttle lever to the afterburner position. Tonight, all the fighters were full of weapons and the take-off weight was very high, so even if the afterburner chamber was opened, the speed of the plane did not increase quickly. You must wait patiently until the end of the runway before pulling it up.

After a while, the J-10 D flew up and soon disappeared into the dark night. Only the navigation lights at the tail and the blue flames at the micro-spout were still flashing.

The second, the third, the fourth...

Six fighter jets of the Shenlong Squadron took off one after another. After reaching a certain height, they flew in formation, turned together and flew towards the attack route.

The navigation lights at the tail of the Dragon Squadron and the flashes of the blue tail nozzle soon disappeared from the view of the tower!

The tail flame of the US F22 is red, while the tail flame of the J-20 and J-10 D is blue. Some people once said that the performance of the J-20 lags behind the F22 based on this point.

The color of the tail flame is different. Is it really because the engine is lagging behind?

First of all, the color of the engine tail flame is actually related to the temperature. Generally, when the temperature generated by the engine is around 2,000 degrees Celsius, the engine tail flame will turn into sky blue, and when the temperature generated by the engine is around 1,000 degrees Celsius, the engine tail flame is orange-red. Therefore, the blue tail flame represents the high temperature of the engine, and the high temperature also proves that the thrust is greater. But this does not mean that the J-20 engine is better than the F22 engine. We see that the F22 produces a red tail flame, because the aircraft does not turn on the afterburner. If the afterburner is turned on, the color of the F22's tail flame is actually blue.

Secondly, the color of the tail flame is related to the position of the engine combustion chamber. When the combustion chamber is close to the nozzle, the temperature of the engine nozzle is higher, and the tail flame is mostly blue. If the combustion chamber of the engine is close to the air inlet, the temperature of the nozzle is lower, so the tail flame is mostly red.

Russia's engines have a combustion chamber close to the nozzle. my country's engines adopt Russian-made engines, so the engine combustion chamber is also close to the nozzle, so the tail flame is blue. The advantage of this structure is that it can make the fuel burn more fully. The structure of the American-made engines and my country's engines is different, so the color of the tail flame is also different.

So the exact point is that the tail nozzle of Russian-made engines is generally blue, while American-made engines are generally red.

Finally, some additives will be added to the aviation fuel used by aircraft in various countries. When the fuel is burned, the additives will react chemically, and sometimes it will cause the color of the tail flame to change. Of course, the additives added by various countries are state secrets and the outside world cannot know.

Therefore, the difference in tail flames of the J-20 and F-22 is actually caused by various reasons. The color of the tail flame cannot tell the performance of the engine.

The Dragon Squadron began to fly in formation. After entering the attack route, the voice of the tower commander sounded for the last time.

"Divine Dragon, adjust the frequency XXXXX, contact the Yellow River, accept its command, wish you success and finish."

"Understand, adjust the frequency XXXXX, it's over." Chen Fei and other team members ended their contact with the tower, adjusted the communication frequency into place, called the early warning aircraft, "Yellow River, Shenlong report, accept your command."

Soon, the early warning plane replied, "Shenlong, adjust the course of 24, enter the attack route as planned, and it is completed."

"I understand! Adjust the course two hundred and four!" Chen Fei confirmed the order.

There is no early warning plane at Pingchuan Base yet.

Of course, this is actually a big deal for Zhang Yunlong. The superiors mean to build a first for use for the base. If the performance is a little behind, the problem of existence or not is solved first, and then the problem of advancedness or not is solved. However, Zhang Yunlong directly refused. He wanted to get it in one step, and he wanted to have a 500 air police officer.

The Air Police 500 is our army’s most advanced early warning aircraft, and he wants this!

Therefore, he coordinated with another base tonight and asked for support temporarily.

Of course, the local military has actually made many requests to request their early warning aircraft to join the base, but Zhang Yunlong was very domineering and refused directly. His meaning was very clear. Since our army was asked to take charge of the Pingchuan base, the key weapons and equipment and command systems must be mine, and the key command must also be listened to. As for ground staff and some irrelevant work, they can be handed over to the local area. After all, it is a joint operation. If you don’t do anything for others, it will not reflect the unity and our sincerity.

However, Zhang Yunlong was very persistent in the early warning aircraft.

Of course, there is no doubt that this action tonight will definitely become a bargaining chip for him to ask for benefits from his superiors. He must be pitiful to his superiors, Chief, look, for such an important action tonight, we don’t even have an early warning plane, and I have to borrow it from my brothers based on my personal relationship. If this is spread, it will be so embarrassing. What do the local troops think of us?

Chen Fei also has some understanding of Zhang Yunlong's temperament.

But to be honest, he still agrees with Zhang Yunlong very much. After all, the Air Police 500 is really delicious!

The first official debut of the KJV 500 was at the 2015 military parade.

At that time, our country had equipped two early warning aircraft, namely the Air Guard-2000 and the Air Guard-200, which both reached the world's advanced level.

Through comparative analysis, we found that the "KJV 500" early warning aircraft is only weaker than the "KJV 2000" early warning aircraft in terms of flight speed and range. However, the "KJV 2000" carrier platform is foreign, and its development will only be subject to others. The "KJV 500" early warning aircraft platform is completely domestic and can be produced in large quantities at any time.

In addition, the performance of the KJW 500 has improved a lot. Its maximum search distance for high-altitude targets is 450 kilometers, and the maximum search distance for sea targets is 350 kilometers. It can search and track 300 targets at the same time.

In addition, the radar of the Air Guard 500 Early Warning Aircraft uses an advanced black technology that is only fully mastered by China - digital array radar technology. The digital array radar technology is two generations higher than the mechanical scanning of the US Early Warning Aircraft and one generation higher than the phased array scanning radar of the Chinese Air Guard 2000 and the Air Guard 200. The Air Guard 500 Early Warning Aircraft uses digital radar components to replace the original analog radar components, which increases the radar's detection accuracy and detection distance while reducing the radar's weight.

Through the above data, we know that although the "KJV 500" is not as good as the "KJV 2000" in range and speed, it has advantages in many aspects. The overall performance reaches and exceeds the "KJV 2000", and it is the most advanced early warning aircraft made in China.

However, it was not the KJV 500 who directed Chen Fei and the others tonight.

"Shenlong, check the main hydraulic pressure lifting instrument and wing status indicator. Finished!"

The early warning aircraft issued a reminder.
Chapter completed!
