Chapter 1231: Kuang Biao fell from the sky for me

After aircraft No. 41175 completed the bomb dropping action, the radar and optical systems that had been ready in advance actually captured the signal of the hypersonic verification bomb in the first time.

But these are indirect observation methods after all.

The most intuitive is still the human eye.

"Unit 15 reports, we have visually confirmed that the missile has been successfully ignited!"

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

After a few seconds, another exclamation followed:

"To be honest, this is so spectacular, just like the legendary seven-colored auspicious clouds..."

The voice was different from that of Deng Yuangang who had been reporting before, and the tone did not sound like he was communicating with the tower.

It should just be a conversation between crew members, and the radio just happened not to be turned off in time.

Sure enough, someone immediately took over the conversation:

"Isn't this thing like a colorful cloud to us?"

As soon as the words fell, a happy atmosphere suddenly filled the cockpit.

"Yes... This is probably one of the most important missions the bomber unit has carried out in the past forty years."

Xuan Yimin, who had just closed the bomb bay and reconfirmed that all the data were normal, also said this.

As a result, Deng Yuangang replied quite seriously:

“这话可不能乱讲，4251号轰6甲空投639是在1967年6月，到现在可还没过40年呢……”

Xuan Yimin couldn't help but curl his lips.

He found that although his captain's words were full of high-sounding clichés, he immediately grasped the detail of the time difference of only a little more than a year, and it was obvious that he cared about this matter very much.

I'm afraid he has already thought about how to leave his name in military history...

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

All that remains is a relaxing and joyful return trip.

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

In fact, when the part about "Colorful Auspicious Clouds" was mentioned, Deng Yuangang had already reacted and switched the communication channel to the internal channel.

However, the magnificent scene mentioned by the pilots made the people in the tower who were waiting for the final news feel a little nervous.

The reason why the test was chosen to be conducted after nightfall was not only to increase the difficulty of optical satellite reconnaissance, but also to avoid the abundant light during the day or the abundant water vapor at dawn and dusk causing overly obvious program effects on the missile.

However, everyone still underestimated the impact of aircraft 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 in charge of missile overall design at the First Academy of Aerospace, walked up to him slowly:

"Academician Chang, the test ballistic missile 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 it is unlikely that anyone will notice..."

The former was not actually worried about this matter at all, and shook his head when he heard this:

"Weather phenomena occurring at an altitude of 30,000 to 40,000 meters can basically be seen within a radius of several hundred kilometers, so someone will definitely notice it."

Then he changed the subject:

"But it's not a big problem. 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 more common in the test launch of medium- and long-range ballistic missiles. Even if it is leaked, outsiders will not know what we launched for a while."

Things like confidentiality have a time limit.

The test must be 100% strict before it is conducted in order to prevent others from making reconnaissance preparations in advance or even sabotaging it secretly.

After the test is completed, as long as it does not involve specific performance parameters or technical details, the problem will not be too serious.

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

After all, it is a hypersonic verification missile. Even taking into account the acceleration and climbing processes, in just a few words, the missile has passed the highest point of its 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 working.

After 2.5 seconds, the 12 explosive bolts surrounding the projectile body detonated simultaneously, compressing the separation spring to push the ineffective power section away from the warhead, and at the same time, according to the law of conservation of momentum, providing the latter with a final boost.

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

But soon it split into many and gradually disappeared from the radar screen.

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

The radar operator's voice came clear and strong over the radio.

A not-so-enthusiastic applause broke out.

Even Chang Haonan followed suit and clapped twice.

Although the entire test has only been completed halfway, it can still maintain normal flight after the separation of the head and body, which at least shows that there is nothing wrong with the aerodynamic and structural design of the verification missile.

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

"Seeker activated!"

This time, the report 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 had withstood the tests of low temperature, vibration, high overload and high speed, and still functioned reliably.

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

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

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

Everyone present couldn't help but hold their breath.

As a result, within a few breaths...

……

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

Over the shooting range.

The high-precision inertial navigation system has been programmed to bring the warhead precisely to the coordinate position set before launch.

According to normal control logic, all you need to do next is stab directly down along the current trajectory.

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

The shooting range, which was modified specifically for this test, is more than 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 sandy background.

In a split second, the onboard computer compares the target outline, which has been simplified to the greatest extent possible, with several key feature values ​​recorded in advance.

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

But it is at the edge of vision.

If it continues to fly along the current trajectory, it will obviously fail to hit the target.

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

The two sets of orthogonal sliders located behind the seeker began to move almost simultaneously, controlling the entire warhead to make small but high-frequency attitude adjustments.

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

The acceleration engine inside the warhead can be completely replaced by the main power section 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 that does not have a large rudder area.

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

With the adjustment of the orthogonal slider, the SAR radar gradually aligns the center of its field of view steadily toward the "special target" that it has identified.

Then, a final acceleration signal was sent to the flight control system.

The solid rocket engine at the very end ignited, emitting a dazzling burst of fire.

The observation station at the shooting range a few kilometers away could only see a sudden flash of light 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 sky from the sky and almost straight to the ground.

The speed is so fast that even a high-speed camera can only capture a discontinuous straight line.

Then, the world fell silent again.

"boom--"

After a full half minute, the deafening crash finally came.

The range observer, holding a radio communicator in his hand, stared in amazement at what was happening before his eyes.

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

A sentence involuntarily emerged in his mind:

"Fellow Daoist who is here to transcend the tribulation?"

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

"The target has touched the ground, confirmed to have hit the shooting range!"

He shouted into the microphone:

"Confirmed to hit the shooting range area!"
