Chapter 1371 "Bird Bird" Flying southwest
All the 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, which greatly limits the range of the missile itself.
But now, all of 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 orbit.
Subsequently, 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-riding body configuration finally began to show its 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, Lift efficiency is several times higher than conventional shapes—
This is the optimal solution iterated by Chang Haonan''s team from hundreds of wind tunnel experiments.
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 can see, the ''Xuanniao'' aircraft has entered the first bounce cycle and has reached the preset flight speed on the upper edge of the adjacent space..."
He turned on the microphone and introduced to the leaders and guests on the viewing platform in front of him:
"Please note that I do not use the Mach number description here, because in some technical data, some researchers will increase the Mach number corresponding to the same speed value by changing the external environment, so we directly adopt the most direct description method... ”
Hearing this, the leader sitting in the center of the front row suddenly leaned forward, and the fatigue caused by running around for days was wiped out.
It literally explains what "a person feels happy when he is 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 at the lower right corner of the large screen:
"Specifically, it''s 11 minutes and 05 seconds."
Just as everyone was communicating, 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 shield, very soon..."
Before he finished his explanation, the red light representing the signal connection status turned green again, and various flight parameters were also displayed one after another.
Chang Haonan points to another screen to show the workflow diagram:
"We have set up two ion flow injection ports on the head cone and back of the aircraft, and directed injection of high-concentration ionic liquids by pushing high-pressure gas. Combined with the deflection of the electromagnetic field, we will use the plasma of the corresponding parts of the radar guide antenna and the data transmission antenna to guide the plasma of the radar guide antenna and the data transmission antenna. The body sheath is precisely weakened.”
"In this way, it can not only ensure the normal operation of each bomb carrier subsystem, but also maximize the use of the plasma layer''s shielding effect on 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 Relying on specially optimized equipment to complete the observations, no air defense system can perform interceptions with speeds of more than 4 kilometers per second and unpredictable ballistics alone.”
"In fact, most radars cannot even be able to track stably..."
…
It seemed to be to confirm his words.
When the "Xuanniao" first cut through the atmosphere, the alarm from the Maodao radar station almost overturned the roof of the control room—
The role of the strategic early warning radar is to issue an alarm before the missile strikes, and now the target it detects has even flew to the hinterland of China and is still rushing towards the radar itself.
"Polarization filtering is invalid! Doppler radial velocity 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. It was a powerful interference caused by tearing the ionosphere open by the wing tip of the wave body, so it can only be based on the current situation. Some signs are speculated:
"It''s changing track?"
Liao Yongcai was not sure what he was facing, so it was difficult to grasp the key to the problem for a while:
"Or it is 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 specifically absorb or scatter signals in the L-band."
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.
“Hell…”
Guo Lin had known for a long time that it was difficult to track this ghostly weapon based on current technology alone, but he never expected that there would be such a big gap that even the landing warning could not be accurately made:
"The bouncing rails are superimposed with ionization interference, and it is impossible to tell which are real changes and which are interference..."
In fact, this radar has been specially designed to strengthen anti-interference algorithms.
But the goal is too outrageous to make it unable to complete the solution in time and needs 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 still unable to grasp the looming target. "call-"
He sighed a little dejectedly and decided to give up:
"Use the data you have obtained so far, calculate where the landing point is."
The coordinates of the shooting range are of course information that everyone knows, but since it is a simulation confrontation, this link is still indispensable.
"But the data is very incomplete and the fluctuations are very large..."
The operator hesitated a little.
"Try it..."
Guo Lin interrupted him directly:
"Anyway, we can''t do anything else."
Following his instructions, the trajectory data is quickly injected into the calculation program.
No mistakes, one song, one content, one in 6, one book, one bar, one reading!
A few seconds later, a result was actually displayed on the screen:
32°34''N, 27°53''E.
When Guo Lin saw this data, he 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 counting a bit wrong? You really fall into Paris..."
…
At the same time, in the underground command center of Dingxin Base, Chang Haonan is still continuing to introduce this technological crystal that embodies the wisdom of almost the entire industry:
"The control of shock waves attached to surface layer 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, while the inner layer is a carbon/silicon carbide composite material with both mechanical and thermal insulation properties. "
"When the missile enters the vertex of each bounce cycle, the onboard computer will adjust the trailing edge shape at a frequency of 500 times per second based on real-time heat flow sensor data, so that the trailing edge curvature of the wave body changes within 2% amplitude. —This seemingly slight adjustment can increase the lift-resistance ratio by 8%, and reserve key energy for the subsequent two jumps. In theory, this technology can also be used in the leading edge, but the material performance cannot be supported for the time being..."
“…”
Before he knew it, the Xuanniao had completed the third jump cycle and suddenly deflected the angle of attack 65 kilometers away from the ground.
With the help of 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-like 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 right away.
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 obvious tremors...
This spectacular scene caused the same ancient poem to 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 network, while the electromagnetic prism vehicle is automatically cleaning the yellow sand stuck to the antenna tube.
"The 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 was enough to accommodate most of the county towns."
The convoy quickly drove away from the shooting range, and the eastern 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.
