Chapter 1371 "Xuan Bird" Flying southwest
All ballistic characteristics of Dongfeng 16 are specially designed to promote this hypersonic warhead, and therefore do not meet the optimal energy utilization rate of conventional ballistic missiles. The range of the missile itself is largely limited. But now, all this has paid off.
The solid rocket engine finishes its work at an altitude of about 200 kilometers and completes the head-body separation within the next second, and formally sends the wave-body warhead into the working track.
Soup later, due to insufficient first cosmic speed, the black bird began to fall slowly under the influence of the gravity field and continued to increase its speed. At the same time, the laser gyroscope built into the flying body began to take over the navigation.
This inertial device, born during the Cold War, is still the pearl at the top of the industrial pyramid, and its drift rate under strong electromagnetic interference is only 0.0005°/h.
Until the moment he pierced into the near space, the exquisite design of the "Xuan Bird" wave body configuration finally began to show his fatal elegance.
The sharp wedge-shaped structure at the front edge of the aircraft is like a scalpel, splitting thin air into two stable oblique shock waves, completely sealing the high-pressure airflow, and forming a compression zone with the lower surface of the aircraft. Like an invisible air cushion, it increases lift efficiency several times the conventional appearance -
This is the optimal solution iterated by Chang Haonan's team from hundreds of wind tunnel tests.
While entering the upper height of the adjacent space, the speed value on the display screen of Dingxin Base finally exceeded 4,000 mark and gradually increased to an astonishing 4,080m/s.
Chang Haonan, who had been silent behind the podium, also breathed a sigh of relief and showed his first smile tonight.
"As you all see, the 'Xuanniao' aircraft has entered its first bounce cycle and has reached the preset flight speed on the upper edge of the adjacent space..."
He Turn on the microphone and introduce to the leaders and guests on the viewing table in front of me: "Please note that I do not use the Mach number description here, because in some technical data, some researchers will change the external environment by changing the To increase the Mach number corresponding to the same speed value, we directly adopted the most direct description method..."
Hearing this, the leader sitting in the center of the front row suddenly leaned forward and ran for days The fatigue brought by it was also wiped out.
It literally explains what "people feel happy when they are happy":
"It takes 4 kilometers per second, so it only takes about 8 minutes to fly over the entire 2,000 kilometers?"
This number shows the power of hypersonic weapons nakedly in front of everyone on the scene.
Even if there is a complete early warning system and transfer plan, it is impossible to complete the operation in such a short time.
"Well... Because the aircraft itself has no power, the speed of the subsequent two bounce cycles will drop slightly, but in general, it will not exceed 12 minutes..."
Chang Haonan used a telescopic antenna that he had temporarily found as a coaching stick and pointed to a countdown in the lower right corner of the large screen: "Specifically, it's 11 minutes and 05 seconds." As everyone communicated, the parameters displayed on the big screen suddenly flashed for a moment, and then disappeared at the same time.
The sudden change made all viewers experience a roller coaster-like mood, with expressions of horror or confusion.
The top bosses can still maintain their complexion, but from the subtle changes in their body posture, it is not difficult to see the shock at that moment.
"Don't worry, this is a signal interruption caused by the plasma shielding layer, very soon..."
Before he finished his explanation, the red light representing the signal connection situation turned green again, and various flight parameters The display has also been restored one after another.
Chang Haonan pointed to another screen to the workflow diagram shown:
"We set up two ion flow injection ports on the head cone and back of the aircraft, which are directed by the push of high-pressure gas Injection of high-concentration ionic liquid, combined with the deflection of the electromagnetic field, the plasma sheath corresponding to the radar-guided antenna and the data transmission antenna is accurately weakened. "
"In this way, each bomb carrier can be guaranteed. The normal operation of the system also makes use of the plasma layer to the maximum extent to shield the electromagnetic waves, giving the flying body a certain degree of radar stealth ability... Of course, this is just by the way, even if the other party relies on specially optimized equipment to complete the observation, it only depends on Speeds of more than 4 kilometers per second and unpredictable ballistics, no air defense system can perform interception. ”
"In fact, most radars cannot even be able to track stably..."
...
It seems to be to confirm his words.
When the "Xuanniao" first cut through the atmosphere, the alarm sound of the Maodao radar station almost overturned the roof of the control room -
The function of the strategic early warning radar is to use missiles An alarm was issued before the attack, and now the target it detected has even flew to the hinterland of China and is still rushing towards the radar itself.
"Polarization filtering is invalid! Doppler radial speed matching failed!"
The operator's voice was a little hoarse, and he watched the faint ghost in front of him blow into a spot on the radar screen. That's it The powerful interference caused by tearing the ionosphere with the wing tip of the wave body is therefore only speculated based on the existing signs: "It is... changing the orbit?" Liao Yongcai I don’t know what I am facing, so I find it difficult to grasp the key to the problem for a while: “Is it a false signal caused by shock wave oscillation?”
Guo Lin's reaction was much faster: "Try using dynamic beam shape... Academician Chang and others may have affected the plasma generation mode to a certain extent, allowing the shield to absorb or scatter specifically. L-band signal. "
The operator who has practiced many times completed the operation at the fastest speed, but the light spot on the screen suddenly appeared in another location flutteringly.
"Hehe..."
Guo Lin had known for a long time that it was difficult to track such a ghostly weapon based on current technology alone, but he never expected that there would be such a big gap. , so that even the landing warning cannot be accurately made:
"The bounce rails superimposed with ionization interference cannot tell which are real changes and which are interference..."
In fact, this radar has specially strengthened the anti-interference algorithm when it was designed.
But the target's too outrageous speed makes it unable to complete the solution in time, so it has to process the new flight trajectory, which completely overloads the data processing capability.
In the next 90 seconds, Guo Lin tried several new methods in succession, but he was unable to grasp the looming target. "Hu——"
He sighed a little dejectedly and decided to give up: "Use the data you have obtained so far, calculate where the landing point is."
Of course, everyone knows the coordinates of the shooting range. but since it is a simulated confrontation, this link is still indispensable. "But the data is incomplete and the fluctuation is very large..."
The operator hesitated.
"Try it..."
Guo Lin interrupted him directly:
"Anyway, we can't do anything else."
According to his instructions, Trajectory data is quickly injected into the calculation program.
No mistakes, one poem, one post, one content, one in 6, one book, one bar, one read!
A few seconds later, a result was really shown on the screen:
32°34'N, 27°53'E.
When seeing this data, Guo Lin was stunned for a moment.
It was not until I turned to look at the map next to me that I realized that this was a location roughly on the Eastern Mediterranean, which was obviously outrageous.
He suddenly thought of the classic photo introducing the booster-gliding ballistics, and took a look at the control cabinet with a wry smile.
"Why are you no longer a bit wrong? You really fall into Paris..."
...
At the same time, Chang Haonan is still in the underground command center of Dingxin Base. Continue to introduce this technological crystal that has condensed almost the entire industry's wisdom: "The control of shock wave surface interference is the core." Chang Haonan pointed to the aerodynamic model and explained:
"The micron-scale honeycomb array on the lower surface of the aircraft, by guiding the boundary layer airflow to form a longitudinal vortex, dispersing the peak of heat flow caused by shock oscillation by 30%. On the upper surface, the gradient ablation ceramic material is distributed layer by layer with an accuracy of 0.2 mm. , the outermost layer is a high temperature-resistant zirconium carbide coating, and the inner layer is a carbon/silicon carbide composite material with both mechanical and thermal insulation properties. "
"When the missile enters the apex of each bounce cycle When the bomb loading computer will use real-time heat flow sensor data , adjust the shape of the trailing edge at a frequency of 500 times per second, so that the curvature of the trailing edge of the wave body changes within 2% amplitude. - This seemingly slight adjustment can increase the lift-resistance ratio by 8%, for the next two times Jump reserves key energy, theoretically this technology can also be used in the leading edge, but the material performance cannot be supported for the time being..."
"..."
Unclearly, the Xuanniao has completed In the third jump cycle, the angle of attack suddenly deflected 65 kilometers from the ground.
With the optical observation equipment near the shooting range, it can be seen that the violent friction between the lower surface of the wave body and the air produces a continuous bright purple glow, just like the umbrella-shaped clouds formed by metal particles blowing up in the ionosphere. .
"Will such obvious reentry characteristics be more likely to be discovered by infrared detection equipment?" Jing Zhiyuan suddenly asked.
But he was destined to be unable to get an answer as soon as possible.
Because in this sentence, the dazzling flash had already pierced the ground from the top of the sky, and the huge impact force even made the optical lens several kilometers away feel a significant tremor...
This spectacular scene made the same ancient poem suddenly pop up in the minds of many people at the scene—
It is suspected that the Milky Way fell into the sky.
…
When the wave body warhead penetrated the 30-meter concrete target, Liang Yangang was using his military boots to crush the last wisp of blue smoke from the launching position.
The camouflage team is re-covering the vehicle with an intelligent camouflage net, while the electromagnetic prism vehicle is automatically cleaning the yellow sand stuck to the antenna tube.
"Circular probability error is 15 meters."
He looked at the design parameters marked on the operating manual and suddenly laughed out loud: "The error of Dongfeng 3 back then was enough to fit most of the county towns."
The convoy quickly drove away slowly At the shooting range, the east skyline was vaguely white.
In high latitudes near the summer solstice, it is always dawning very early.
Fortunately, the area where the missile brigade stayed was still a lifeless desert, with only the shadow of a sand dune slightly deeper than a few hours ago-
That was the only scar left in the digital world when the mysterious bird penetrated the iron curtain of the era.
