The military-industrial scientific research system of the academic master

After aircraft No. 41175 completed the bombing action, the radar and optical systems that were already ready actually captured the signal of the hypersonic verification bomb at the first opportunity.

But these are all indirect observations after all.

The most intuitive thing is still the human eye.

"Unit No. 15 reported that we have visually confirmed that the missile was successfully ignited!"

The pilot's voice came almost immediately after the radar station's confirmation signal.

After a few seconds, another exclamation followed:

"To be honest, this is so spectacular, just like the legendary colorful clouds..."

His voice was different from Deng Yuangang who had been reporting before, and his tone didn't sound like he was communicating with the tower.

It was probably just a conversation between the crew members, and the radio just hadn't been turned off yet.

Sure enough, someone immediately picked up the call:

"For us, isn't this thing just a colorful auspicious cloud?"

As soon as the words fell, a joyful air suddenly filled the cockpit.

"Yeah... This is probably one of the most important missions the bomber force has performed in the past forty years."

Xuan Yimin, who had just closed the bomb bay and reconfirmed that all the data was normal, also followed suit.

As a result, Deng Yuangang replied quite solemnly:

"Don't say this nonsense. No. 4251 bombed the 6A airdrop with 639 in June 1967. It's not even 40 years ago..."

Xuan Yimin couldn't help but curl his lips.

He found that although his captain's mouth was full of high-sounding stereotypes, he caught the details of the time that were only a little more than a year apart at the first time, and he was obviously very concerned about this matter.

I'm afraid I have already thought about how to leave my name in military history...

For the four crew members, their mission was completely completed when the verification bomb was successfully dropped from the bomb bay and ignited.

All that's left is a relaxing and enjoyable return trip.

However, the mission of Chang Haonan and others has just begun.

In fact, when the "Colorful Auspicious Clouds" section was mentioned, the communication channel had already been switched to the in-camera channel by Deng Yuangang who had reacted.

But the magnificent scene mentioned by the pilots made the group in the tower waiting for the final news feel a little nervous——

The reason why we chose to conduct the test after dark was not only to increase the difficulty of reconnaissance of optical satellites, but also to prevent sufficient light during the day or strong water vapor at dawn and dusk from bringing too obvious program effects to the missile.

However, everyone still underestimates the impact that aircraft will have on the surrounding environment when flying at hypersonic speeds in the atmosphere.

Looking at Chang Haonan, who was silent with his arms folded, Xing Muchun, who was responsible for the overall missile design of the First Aerospace Academy, walked slowly up to him:

"Academician Chang, the test trajectory was launched from the central part of Longyuan and hit the western part of Longyuan. This area is sparsely populated, and today is New Year's Eve. Most people will be at home at this time, so no one will notice..."

The former was actually not entirely worried about this matter. Hearing this, he shook his head:

"Weather phenomena produced at an altitude of 30,000 to 40,000 meters can basically be seen within a few hundred kilometers, and someone will definitely notice it."

Then the conversation changed again:

"But the problem is not big, at least there is no tadpole cloud or twilight effect that can directly reflect the flight speed... According to the pilot's description, it should be an irregular trail that is common during test launches of medium and long-range ballistic missiles. Even if it is spread, outsiders will We won’t know for a while what exactly we launched.”

Things like confidentiality are time-sensitive.

The test must be 100% strict to prevent others from preparing for reconnaissance in advance or even sabotaging it secretly.

After the test is completed, as long as specific performance parameters or technical details are not involved, the problem will not be too big.

After hearing Chang Haonan's final words, the rest of the people felt relieved and returned all their attention to the big screen in front of them.

After all, it is a hypersonic verification missile. Even if the acceleration-climbing process is included, in just a few words, the missile has passed the highest point of the ballistic trajectory and entered the terminal dive process.

135 seconds after the missile was launched, the liquid rocket engine, which had reached its scheduled working time, stopped running.

After 2.5 seconds, the 12 explosive bolts surrounding the projectile detonated simultaneously. The compression separation spring pushed the power section that had lost its function to separate from the warhead. At the same time, according to the principle of conservation of momentum, it gave the latter a final boost.

On the radar screen, the signal strength marked GC-X subsequently weakened, and another stronger echo was generated below it.

But soon it was divided into multiple points and gradually disappeared from the radar screen.

"Longyuan Observation Station reports that the head and body are separated and the target's flight trajectory is normal!"

The clear, strong voice of the radar operator came over the radio.

A burst of moderate applause broke out.

Even Chang Haonan also took two shots.

Although the entire test is only halfway through, it can still maintain normal flight after the separation of the head and body, which at least shows that there are no errors in the aerodynamic and structural design of the verification projectile.

After passing the highest point of the ballistic trajectory, the target speed begins to increase at a speed visible to the naked eye.

"Seeker activated!"

This time, the reporting sound came from inside the tower.

On the big screen, the green lights corresponding to the two guidance systems all lit up, proving that the missile-borne electronic equipment has gone through the tests of low temperature, vibration, high overload and high speed, and still functions reliably.

Of course, at such an amazing speed, it is already very difficult to send back some key signals.

As for what the seeker specifically captured and how to distinguish the target, it can only be deduced from the hit situation and the terminal trajectory data.

The signal detected by the radar has reached the top of the shooting range area.

Everyone present couldn't help but hold their breath.

As a result, in just a few breaths...

...

At the same time, somewhere in the western part of Longyuan.

Above the shooting range.

The high-precision inertial navigation system has been set according to the program, bringing the warhead to the coordinate position set before launch.

According to the normal control logic, the next step is to just follow the current trajectory and go straight down.

But the second missile-borne SAR radar has captured a different imaging picture.

This shooting range specially modified for this test is not just a crosshair drawn on the ground.

Instead, they used special cement and paint to lay out a variety of simulated targets with clear outlines within a radius of about two kilometers.

In the SAR's field of view, the radar reflectivity of these targets is completely different from that of the sand as the background.

In a flash, the onboard computer compared the target outline that was simplified to the greatest extent with several key feature values ​​recorded in advance.

It quickly identified the one with the most edges and corners and the highest degree of feature fitting.

But it was at the edge of the field of view.

If it continued to fly along the existing trajectory, it would obviously not be able to hit the target.

In the next 0.1 second, the SAR radar with a higher terminal priority took over the flight control system.

The two sets of orthogonal sliders located behind the seeker began to move almost at the same time, controlling the entire warhead to make small but extremely frequent attitude adjustments -

In fact, from the perspective of increasing the terminal speed alone, the separation of the head and body is not a completely necessary design.

The acceleration engine inside the warhead can be completely replaced by the main power stage with a longer working time.

But the single-stage design means that the flying body has a larger mass and requires a stronger torque to overcome inertia.

This is undoubtedly a big problem for the verification missile without a large-area rudder.

A relatively smart warhead, however, does not need to worry about these.

Under the adjustment of the orthogonal slider, the SAR radar gradually aimed the center of the field of view steadily at the "special target" it had identified.

Then, it sent the last acceleration signal to the flight control system.

The solid rocket engine at the very end ignited, ejecting a dazzling flame-

The range observation station a few kilometers away could only see a flash of light suddenly flashing in the sky beyond the field of vision.

In just a blink of an eye, the flash turned into a dazzling white line, cutting through the night from the sky, and almost straight to the ground.

The speed was so fast that even high-speed cameras could only capture an intermittent straight line.

Then, the world returned to silence.

"Bang--"

After half a minute, the deafening sound of the collision finally came.

The range observer, holding a radio communicator in his hand, stared at what was happening in front of him in amazement.

The lightning flash just now seemed to still remain on the retina...

A sentence involuntarily emerged in his mind:

"Which Taoist fellow is here to overcome the tribulation?"

It was not until a voice asking about the situation came from the radio that the observer's consciousness was brought back to reality.

"At present... the target has touched the ground, and it is confirmed that it has hit the shooting range area!"

He shouted loudly into the microphone:

"It is confirmed that it has hit the shooting range area!"
