The ups and downs of life in the Siheyuan

The ground radar operator heard the instruction, stood up and reported listlessly: "No target found."

"What? What are those three little guys in the sky? They are 12 meters long and have a wingspan of 14 meters."

"Is our radar already so bad? Didn't we say before that our Doppler radar is already equipped? That's it!"

. . . . . .

The commentator quickly spoke:

"Dear heads, Red Arrow 1 is a stealth drone. Its whole body is covered with a stealth material skin, which can effectively absorb radar waves.

At the same time, the excellent appearance design can effectively reduce the reflection of radar waves."

Stealth technology is already a hotly discussed term at the moment, and there is also research in the country, but it is just getting started.

In the 20s, America successfully developed the U-50 high-altitude reconnaissance aircraft with certain stealth capabilities, taking the lead in the field of stealth.

In 1973, America initiated a project to develop a stealth fighter, which was the F-117A.

F-117A攻击机由洛克希德公司于20世纪70年代中期开始研制，1981年首飞定型，1983年服役，1988年首次公布。

Therefore, those who have the honor to attend this appraisal meeting today are all experts or senior military officers in the aviation field.

They are very familiar with stealth technology.

It's a pity that China's current main fighter jets are still first-generation, or barely called one-and-a-half-generation fighters.

All forces are working hard to break through the third-generation aircraft.

The emergence of the Turbofan 8 has allowed everyone to see the shadow of the third-generation aircraft.

Some research institutes are thinking about improving turbofan 8 and working hard to move towards the fourth generation aircraft.

Today I was suddenly informed that the three drones in the sky were actually the famous fifth-generation aircraft.

This made the people who didn't know the inside story calm down, and there was a lot of noise.

Currently, the mainstream fighter aircraft in the world are still third-generation aircraft, and only America has called out the slogan of researching fifth-generation aircraft.

How to distinguish the differences between generations is briefly described here.

First-generation aircraft: The basic feature is high subsonic speed, a mature model based on early jet aircraft. The main weapon is the cannon. The combat mode is basically combat within visual range.

Representative models: Yak-15 fighter, Yak-17 fighter, etc.

Second-generation aircraft: The basic characteristics are high-altitude and high-speed pursuit, and they begin to be equipped with missiles as weapons, which can usually exceed the speed of sound and reach around Mach 1.3.

Representative aircraft models: John Bull's Lightning fighter, Gaul's Mirage fighter, MiG-21 interceptor, etc.

Third-generation aircraft: refers to supersonic fighter jets, with a speed of at least Mach 1.3.

It can carry multiple single-barrel weapons. The main weapon is air-to-air missiles. It has stronger ground control capabilities and also has air combat capabilities.

Representative models: F-15, F-16, MiG-25, etc.

Fourth-generation aircraft: The flight speed is still maintained above Mach 1.3. The aircraft has a wide range of models and uses, and is equipped with avionics nuclear weapons systems.

Representative models: F16, F18, MiG-29, Su-27, Mirage 2000, Tejas, J-10, J-11, etc.

Fourth and a half generations: Its performance exceeds that of fourth-generation fighters, but it does not have the stealth capabilities of fifth-generation fighters. It cannot be said to be better or worse than fifth-generation fighters, so it is called fourth-and-a-half-generation fighters.

Representative aircraft models: Su-35, Typhoon fighter, Rafale fighter, Gripen fighter, J-16 fighter, etc.

The biggest feature of fifth-generation fighters is stealth. The reflection area of ​​a huge fighter jet may be about the same as that of a small bird, making it impossible to identify it.

In addition, the fifth-generation fighter aircraft also has a high-intensity electronic station, which integrates communication, navigation and identification avionics technologies, can provide data fusion between multiple platforms and multiple sensors, and has high-bandwidth, low-interception data transmission capabilities.

Representative models: F22 and F35, J-20 fighter.

"It can't be true, I have a bad heart, you can't lie to me."

This expert heard that he was participating in a stage report meeting of an aircraft. He didn't take it seriously at first. When he saw three strange-looking aircraft, he was shocked.

When he learned that it was a drone, he was even more surprised. He didn't react for a long time.

"Our current communication technology is so powerful that we can enter the field of drones." He couldn't believe it in his heart, but there was hope.

He also participated in the reverse research of an air-to-air missile. It was not until we copied the Thunderbolt 2 that he realized the technological gap with developed countries.

I remember that we obtained an American Sidewinder air-to-air missile in 58. Although we invested a lot of manpower and material resources in reverse research.

It's a pity that our understanding of electronic technology is in a primitive state. To put it mildly, we are making slow progress, but in fact we don't understand it at all.

After learning the news, Polar Bear used P-12 medium-range missile technology in exchange for imitated air-to-air missiles.

Obviously, the technology of P-12 medium-range missile is much higher than that of Sidewinder missile.

After obtaining the missile, they quickly conducted in-depth research on it, and finally copied the K-1961 air-to-air missile in 13 and put it into mass production.

In order to maintain a good relationship with our country, Polar Bear shared the technical information of the K-13 air-to-air missile with us as promised, and provided the MiG-21 fighter jet free of charge.

After we localize it, we call it the PL-2 (PL-2) short-range air-to-air missile.

Until now, we have been learning military technology from behind each other.

He had been holding back the demonstration just now, thinking in his mind whether this was technology purchased from America.

But it was hard for him to believe in that kind of communication technology and networking technology.

This kind of technology must be the latest technology in America. How can it be exported unless they are crazy.

Now tell him that this is not only a high-tech drone, but also a TMD stealth drone.

Since it can be used as a stealth drone, the same technology can be applied to fighter aircraft.

There are many people who think like him, and they continue to seek confirmation.

The officer in charge of the ground radar had the same reaction as these people at first.

Perhaps more strongly than these people's reactions.

This is Kyoto, and their ground radar cannot detect the high-speed flying Red Arrow 1 in the sky.

The frustration that was visible to the naked eye and the radar had no response made me almost think that the radar had failed.

Now, he has long accepted it, and seeing these people's reactions makes him happy.

Under the command of the tower, the three drones landed on the runway one by one.

Before entering the hangar, he was surrounded by a crowd of people. They touched the fuselage with their hands and kept asking questions.

Some emotional people shed tears on the spot.

"We have a stealth machine! We have a stealth machine!".

"Yes, it's beautiful!"

"It can actually hold 2 tons of ammunition?"

"Yes, its flight speed can exceed Mach 2.5, its maximum cruising radius is 1500 kilometers, its maximum range is 4000 kilometers, and its maximum cruising time is more than 6 hours."

The commentator was sweating profusely and was constantly being pulled over to answer everyone's questions.

"At such a speed, once you break through the defense quickly, won't it be impossible to stop it?" Several officers were talking.

"Our little mushrooms only seem to be 1.5 tons, hehe, what if..." One of the officers was very imaginative.

"No, 1.55 tons per hour."

"It's still the same, it can be pretended." The imaginative officer's eyes lit up.

The other officers all reacted.

"It's a pity that the flight is a bit short. We are kilometers away from America."

"Hey, there are always more solutions than difficulties!"
