Chapter 1231 Kuangbiao fell from the sky for me
After aircraft No. 41175 completed the bombing action, the radar and optical systems that had been ready actually captured the signal of the hypersonic verification bomb at the first time.
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 sigh followed:
"To be honest, this is so spectacular, just like the legendary colorful 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 the crew members, and the radio just hasn't had time to be turned off.
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 happy air suddenly filled the cockpit. .
"Yes... This is probably one of the most important missions that the bomber force has performed in the past forty years."
The bomb bay has just been closed and the data has been reconfirmed Normal Xuan Yimin also said.
As a result, Deng Yuangang replied quite solemnly:
“You can’t say this nonsense. No. 4251 bombed the 6A airdrop of 639 in June 1967, and it has not been 40 years yet. ..."
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 was 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 a 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 is left is a relaxing and pleasant 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 of people 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 is from Long Launched from the central part of the country, it hit the western part of Longyuan. This area The domain is already 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 that occur 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 topic changed:
" But the problem is not big, at least there is no tadpole cloud or tadpole cloud that can intuitively reflect the flight speed. Or the twilight effect... According to the pilot's description, it should be an irregular contrail that is common during test launches of medium- and long-range ballistic missiles. Even if it is spread, outsiders will not know what we are launching for a while. "
Confidentiality is time-sensitive.
Before the test, it 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 sentences, 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 brought the last blast to the latter. 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 reported that the head and body were separated and the target's flight trajectory was normal!"
The clear and powerful voice of the radar operator sounded on the radio.
A burst of moderate applause sounded.
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 sets of guidance systems all lit up, proving that the missile-borne electronic equipment has passed the test of low temperature, vibration, large overload and high speed, and still functions reliably.
Of course, at such an astonishing speed, it is already very difficult to be able to send back some key signals.
As for what exactly the seeker captured and how to distinguish the target, we can only deduce it based on the hit situation and terminal ballistic data.
The signal detected by the radar has reached above the shooting range area.
Everyone present held their breath involuntarily.
As a result, in just a few breaths...
...
At the same time, somewhere in the west of Longyuan.
Over the shooting range.
The high-precision inertial navigation system has been programmed to bring the warhead to the coordinate position set before launch.
According to the normal control logic, you only need to plunge directly according to the current trajectory.
But the second set of missile-borne SAR radar has captured a different imaging picture.
The shooting range specially modified for this test is not just a crosshair on the ground.
Instead, special cement and paint were used to lay a variety of simulated targets with clear outlines within a radius of about two kilometers.
In the SAR field of view, the radar reflectivity of these targets is completely different from that of the background sand.
In the blink of an eye, the missile's computer compares the most simplified target profile with several key characteristic values that have been recorded in advance.
I quickly identified the one with the most edges and corners and the highest degree of feature fitting.
But it is at the edge of the field of vision.
If you continue to fly according to the current trajectory, you will obviously not be able to hit the target.
Within the next 0.1 seconds, the SAR radar with higher terminal priority took over the flight control system.
Two sets of orthogonal sliders located behind the seeker head start moving almost simultaneously, controlling the entire warhead to make small but extremely frequent attitude adjustments -
In fact, from the perspective of increasing the terminal speed , the 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 greater mass and requires stronger torque to overcome inertia.
This is undoubtedly a big trouble for the verification projectile without a large area rudder.
A relatively smart warhead does not need to worry about these.
Under the adjustment of the orthogonal slider, the SAR radar gradually pointed the center of the field of view steadily at the "special target" it identified.
Then a final acceleration signal was sent to the flight control system.
The solid rocket motor at the end ignited, ejecting a dazzling fire light——
The shooting range observation station a few kilometers away could only see a sudden flash of light in the sky outside the field of vision. A ray of light.
In just the blink of an eye, the flash turned into a dazzling white line, cutting through the night from the sky, almost straight to the ground.
The speed is so fast that even high-speed cameras can only capture an intermittent straight line.
Then the world returned to silence.
"Bang——"
After half a minute, the deafening impact sound came belatedly.
The range observer, radio communicator in hand, stared dumbfounded at what was happening.
The thunder-like flash just now seemed to still remain on his retinas...
A sentence involuntarily emerged in his mind:
"Where is the road? Are you going to survive the disaster here?”
It wasn’t until the voice asking about the situation came from the radio that the observer’s consciousness returned to reality.
"The target...the target has touched the ground, it is confirmed to hit the shooting range area!"
He shouted into the microphone:
"It is confirmed to hit the shooting range area!"
