Just like when the J-20 first started its test flight, this time the J-20's test flight of Dongchen's "Falcon" engine was not deliberately kept secret. Moreover, it can be seen from the eye-catching "Falcon" character on the engine position of the aircraft.
The country’s test flight of the J-20 this time was actually quite high-profile.
There is no martial law at the test airport, which allows reporters who have received the news to take pictures freely outside the airport, and can easily record the dexterous movements of the aircraft in the air as if they were playing in the air. The photos and videos of these scenes are spread through the Internet and the media.
After that, netizens all over the world began to discuss and argue around the new J-20. Some people believed that the J-20 already had the world’s most powerful payload capacity among fighter jets. With the support of this payload capacity, the J-20
The new facelift has a great chance of surpassing the F-22 and becoming the most powerful fighter in the world. However, some people believe that the F-22's avionics performance, stealth performance and unparalleled strike performance are inferior to the J-20 anyway.
Can't catch up.
Even the Americans think so. In their eyes, even if the J-20 has a more powerful payload capacity, it only enhances the J-20's ground attack capability and combat radius. However, it is absolutely impossible to enhance its ability to face the enemy in the air.
In terms of survivability as a fighter jet, although the F-22 lags behind the J-20 in terms of power performance, the most important thing is the F-22's undiscoverability and preemptive advantage.
However, just when Americans were still looking for a new step for themselves, Dongchen once again announced an earth-shaking event with a high profile.
That is, Dongchen is going to develop a new generation of phased array radar!
Radar is like the eyes of a fighter jet. In the era when fighter jets were just born, all air combat relied on sight distance and shooting distance. There was only one way to attack the opponent, which was to discover first and then strike. However, since radar and air-to-air combat
With the emergence of air-to-air missiles, this pattern has begun to undergo tremendous changes. The model of detecting first and then striking has fallen behind. Fighters from various countries are competing to see who can detect the opponent first and then strike first.
Under the modern air combat pattern, air combat is no longer the era of machine guns sweeping within visual range. Today's air combat really relies on radar visual range. Moreover, the accuracy of missiles is much greater than that of aircraft cannons and machine guns. This also means that who
Whoever discovers the opponent first and launches the missile first may be able to shoot down the opponent and protect himself at the same time.
The most impressive achievement of the F-22 is not its power, but its avionics performance, strike capabilities and stealth capabilities. It has achieved the smallest radar reflection surface, which also means that it has the opportunity to lurk in the opponent's radar.
It lasts longer, and his powerful avionics performance also ensures that he can discover the other party at the first time, before others have discovered him. In this case, the enemy generally cannot achieve true success with him.
In battles, one is often hit by a missile before the radar detects the opponent.
However, if the radar that Dongchen is about to develop is far superior to the F-22 radar, what will it be like?!
If the F-22's stealth capability is greatly weakened in front of Dongchen's radar, what will happen?!
Modern fighter aircraft have a far cry from their protective capabilities and strike capabilities. No matter how sturdy the aircraft is, if it is hit by an ordinary air-to-air missile, it will inevitably face the result of crashing. Even if China's air-to-air missiles are not as good as F
-22 carries anti-air missiles, but it is enough to destroy the F-22.
When Dongchen announced that he was going to develop radar, the whole world felt a burning sensation in their buttocks. This time, it may be difficult to sit still.
The Americans began to evaluate Dongchen's electronic equipment manufacturing capabilities. Based on Dongchen's current strength, they analyzed what advantages Dongchen has in the radar field. The Russians are also doing the same thing. The most difficult one is India. They
I was so worried that I couldn't sleep. All I could think about was, what kind of weapons does the United States have that can contain China's J-20 and Dongchen's radar? What kind of weapons does Russia have that can do this? And what's more?
How can I get such a weapon?
Dongchen suddenly turned to the defense industry, catching the whole world off guard.
Domestic executives are also looking forward to Dongchen at this moment. The success of the "Falcon" engine has allowed them to see the huge potential of Dongchen again. And now, Zhang Wenhao has taken root in Jiangcheng and begun to develop Dongchen's phased array radar.
And three-dimensional navigation satellites.
The waiter has a higher pursuit of phased array radar. When designing the research and development plan, the waiter said to Zhang Wenhao: "Boss, if we continue to develop phased array radar, it will no longer make much sense."
Zhang Wenhao was puzzled, frowned and asked: "Why is it no longer meaningful? Isn't phased array radar the mainstream radar now?"
The waiter nodded and said: "It is true that the current mainstream radar is true, but this kind of radar has a fatal flaw. Even if it can track more targets at the same time, the way it detects targets has not changed fundamentally.
change."
Zhang Wenhao frowned and asked, "What do you mean?"
The waiter explained: "Look, today's radars basically use radar waves as the basic means of detection. How do radar waves work? It is an electromagnetic wave that is uncontrollable when it is emitted, just like if you close your eyes
Hold a basin of water and splash it out. If you are not splashed by the water, it means that there is no obstruction around you. Once you are splashed by the water, it means that there are objects around you that block the movement of the water and bounce the water back.
Come back, right?"
Zhang Wenhao nodded and said, "Yes, what next?"
The waiter smiled and said: "Then the problem arises. The water poured out is the same as the radar waves released. We cannot control it ourselves. The radar waves touch the object and are reflected back, so that the radar can identify the other party.
If the radar waves are absorbed or interfered with and refracted and never return, wouldn't the radar be useless? Today's stealth aircraft use this principle. The radar reflective surface is extremely small, and severe refraction occurs during reflection. In this way,
Now, the projected radar waves have no information, as if they were lost in the ocean. The operating principle of radar is based on the safety criterion of not being able to receive the reflected radar waves. In this way, it is difficult for the radar to achieve true reflection.
hidden."
Zhang Wenhao couldn't help but ask: "Then what good idea do you have?"
The waiter smiled and said: "The method is very simple, that is, combine it with three-dimensional satellite navigation technology."
Zhang Wenhao thought for a moment and then asked: "Do you want to design radar waves to be controllable and measurable like the signal waves of navigation satellites?"
"That's right." The waiter smiled and said: "Boss, you are really clear. If we use this technology on radar, then the radar waves that come out will not be water poured out, but lines released. We
Being able to detect the entire route of the radar wave in real time, we can all know clearly whether it is absorbed or reflected back when it encounters an object. The simplest way is to use the precise ranging of our satellite navigation. If
The radar detection distance is 300 kilometers, so the radar waves we emit must reach a length of 300 kilometers. If, according to our calculations, some radar waves disappear when they just reach a length of 100 kilometers, then we
It can be concluded that there is an object that can absorb radar waves at a position of one hundred kilometers. If our radar waves do not run in a straight line, but turn after being refracted by a mirror-like surface, we can also detect the specific direction of its turn.
Position, in this way, the stealth aircraft will completely lose its effect. Whether it absorbs radar waves or refracts radar waves, we can easily detect its presence."
Zhang Wenhao was overjoyed and exclaimed: "This idea is so smart! If the three-dimensional satellite navigation system and radar technology are really combined, then the effectiveness of the radar will almost reach 100. The existing stealth technology,
It’s not enough to fool this smart radar.”
"That's right." The waiter nodded repeatedly and said: "In this way, the F-22 has completely lost its stealth specialty. Moreover, the most important thing is that the radar we designed has higher power and longer detection range.
This indicates that aircraft equipped with Dongchen radar can discover the opponent first and launch an attack before the opponent discovers itself."
Zhang Wenhao couldn't help but said: "This kind of radar technology is definitely a killer weapon. Its significance is much greater than that of the "Falcon" engine. If it is equipped with this kind of radar system, even our J-10 may
In actual combat, we can pre-emptively shoot down the F-22. If this radar is brought to the ground and provides guidance for our air defense missiles, the entire country's air defense capabilities will be qualitatively improved."
"Yes." The waiter nodded and said, "If we really apply this radar to all air combat and air defense fields, I think this air defense system will be the most powerful one in the world.
Not to mention the United States, even if fighter jets from all over the world come one by one, they cannot escape radar monitoring. In this case, our air defense missiles will have enough time to lock on the target, and have a powerful and stable radar as a guide.
.”
Zhang Wenhao nodded slightly. The power of the F-22 lies in its excellent stealth performance. Not only is it extremely difficult for ordinary radar to detect him, but even if it is discovered, it is impossible to keep track of him. If the angle of the F-22 changes slightly,
The radar reflection wave may be interrupted, and it takes at least several seconds or even ten seconds for a general anti-aircraft missile to lock on the target. If the radar cannot buy this time for the missile, then the missile will not be able to lock on the target at all.
, even the conditions for launch are not met.
However, once this new type of radar comes out, the entire process of the F-22 from entering the detection range to leaving the detection range will be under the control of the radar! (To be continued. If you like this work, you are welcome to come to Piaotian Literature
