Chapter 1374 The flash above Longyuan
A little later that day.
In the western part of Longyuan, mass effect shooting range.
Before the morning mist on the Gobi Desert was dispelled by dawn, Wang Hongrang's lightning protection boots had crushed the last thin frost at the entrance of the blockade line in the bomb drop zone.
He took a deep breath and moved his foot closer to the electric heating equipment next to him to dispel the coldness that spreads through the gaps in the joints—
The natural environment in the Northwest is so strange that even though it is already mid-June, frost weather around single-digit ℃ will still occur occasionally.
Once the daylight enters the temperature, the temperature will quickly rise to above 30℃.
For those of them who may continue to work for several hours or even longer, they can only choose to temporarily endure the cold.
After all, heat stroke can really kill people. "Director, it's a pity that you didn't see it with your own eyes when the bullet landed just now."
Chief of Staff Ai Xiaofeng said next to him: "I thought it was an earthquake..."
He was only in his early 30s and was still studying at the Second Artillery Engineering College in 1996. He has not participated in the last few underground nuclear tests conducted by China.
The sound and light effects of any conventional weapon hitting the target were far less gorgeous than the "Xiao Bird" this time.
Wang Hongrang smiled mysteriously after hearing this.
About three hours ago, when Xuanniao hit the target, he was indeed checking the work of each sensor in the underground control room, and did not go with the political commissar and other participants.
But these young people in front of me didn't know that there was an optical periscope left behind more than ten years ago.
Not only does not delay the observation, but the vision is wider than the platform located on the top floor of the camp office building.
But after thinking for a while, Wang Hongrang decided to keep this secret for the time being and not to destroy the other party's good mood.
Wait until the right time to reveal the truth.
"It's okay, haven't we seen that hypersonic verification bomb before..."
He replied indifferently:
"Besides, we also have a high-definition video material for the whole process. All of them are left, and there is time to watch slowly in the future."
"Tsk tsk..."
Ai Xiaofeng was indeed fooled:
"It's very different from the previous one. It's probably difficult to intuitively feel it through video materials..."
"..."
"Yes."
Wang Hongrang thought silently in his heart.
Although he was teasing the little brother's idea, he had to admit that the other party's statement was fine.
Ai Xiaofeng wanted to say something else, but Wang Hongrang suddenly raised his wrist and glanced at the Beidou timepiece on the military green dial.
The words 02:31 are fluorescently tuned on the light cyan background.
The latter's voice became serious: "Enter the target area in fifteen minutes!"
For safety reasons, personnel need to wait an hour after the end of the bomb drop. Only then can you start your homework.
In fact, in the outline, this interval is longer. It is only because the Xuanniao did not install a warhead and the special confidentiality requirements for this test that the cooling time was compressed after the evaluation.
As the order was issued, Ai Xiaofeng also curled his smile and began to check the wear of protective clothing and protective equipment with the other eleven people. The crisp sound of the metal buckle swept into the concrete protective corridor. echo of .
"Old Wang, the vibration monitoring data has come out, I am transmitting it to you."
The voice of political commissar Qiu Yijun came from the bone conduction headset in the helmet, with electronic filtering The unique rustling sound of the instrument.
On the military-reinforced computer screen in front of you, the three-dimensional geological model is reenacting the impact moment at a slow speed of thousands of times.
As the black bird's ejection penetrates the last thirty meters of concrete layer, dark red heat flows stirred Mach rings on the surface of the tungsten carbide head cone.
To ensure hit, the underground concrete fortification was still selected as the target for the first launch, and the simulated nuclear bomb silo was moved to subsequent tests.
Wang Hong asked to gently drag the mouse to peel off the geological faults of 500 meters around the simulated bounce point layer by layer.
The high temperature generated by the leading edge of the cone during the impact made the support beam of the simulated command post twist like melted chocolate, which reminded him of the first time he saw a tungsten alloy armor-piercing bomb twenty years ago. Slow-motion playback of breaking through ten-layer steel plates. "Good guy, there are dense broken belts in some areas around the path of the warhead penetrates, and the invading surface shows the rupture of radial cracks and circumferential cracks, and together with the invading surface, it forms a meter A first-level size crushing pit..."
Ai Xiaofeng's protective mask was covered with water vapor, but his voice was excited: "This is the first time I have seen the cracking of a concrete target exceeding 50%. "
Under normal circumstances , Since concrete does not have strong elasticity, a crack of about 15% is enough to think that the entire target is destroyed.
As for 50%...
Even what this number represents, we have to think specifically about it.
He could not wait to see what the target looked like at this moment.
"The shock cone formed by the wave-multiplier configuration when the end of the wave-multiplier structure increases the kinetic energy density at the end of the ballistic by 47%. Look at this--"
Wang Hongrang calls out the damage map , it can be seen that in the concrete layer represented by purple, ferocious spider-web-like cracks spread to almost every corner.
Around the invasion path, a large number of compression shear cracks appeared directly, as if the concrete in that space had never existed.
"The average vibration velocity amplitude of the sampling point on the upper surface of the structure reached 75.4m/s, and the sampling point on the lower surface was 21.9m/s. This is just a process of invasion. If you consider charging again..."< br>
Speaking of this, Wang Hongrang hesitated for a moment: "No, this destructive power is similar to the explosion process. Even if you consider charging, it will only cause a larger range of damage to the inside of the structure." Ai Xiaofeng Then he continued the conversation next to him: "Or...it can also be targeted with greater depth."
The work process of conventional ground drilling and blasting can be roughly divided into The two steps of invasion and explosion are simply to penetrate the kinetic energy to a certain extent and then detonate the charge. The principle similar to "fighting a cow across the mountain" can cause damage to the depth that cannot be directly reached.
"Big deep..."
The 30-meter depth of the target of the No. 3 shooting range is real concrete, which is at least equivalent to the standard of 70-80 meters based on ordinary soil layers.
There are only a few goals with higher specifications in the world.
Considering the range of 2,000 kilometers...
Wang Hongrang seems to have already made some guesses.
Just as I was speaking, the red warning light above the door of the protective corridor suddenly turned green, and a prompt sound began to sound from the speaker.
This is a signal that the job is allowed.
A group of twelve people opened the explosion-proof door and took a car to the interior of the target area No. 3.
No mistakes, one poem, one post, one content, one in 6, one book, one bar, one read!
Also because there is no detonation process, no large-sized cavity is generated in the underground part, and the safety factor on the surface is relatively high.
Even so, Wang Hongrang was still cautious every step he took. It took more than ten minutes to finally reach the hit point, and turned on the tactical flashlight fixed on the side of his helmet, leaning over and looking down.
"I'll go..."
A lieutenant at the end of the team was the first to express his feelings.
Following the cold white light column, the conical rupture of several meters in diameter came into everyone's eyes, like a wound in the crust pierced by the sword of the gods.
The ablation marks on the inner wall of the channel show a strange spiral pattern, which is the mark left by the injection when it contacts at a speed of Mach 10, and the air is ionized into a plasma state.
"Incredible..."
Wang Hong asked to squat and grab a handful of rock chips, feeling the slight tingling sensation from his fingertips.
For a moment, he was even a little difficult to tell whether it was because of the sharp edges of the debris or the residual heat generated by the invasion process that had not yet dissipated.
"This is completely penetrated..."
"The reinforced concrete at the edge of the crater shows molten vitrification characteristics, indicating that the instantaneous temperature is far exceeding 1500℃..."
< br>
Ai Xiaofeng judged while pressing the shutter.
At this time, no one can write slowly with a notebook, so they are recorded through audio and then summarize slowly after going back.
"Didi---"
The radiation detector of the chemical protection group suddenly beeps, and everyone subconsciously takes a half-step back.
The leader of the three-defense team, who was supposed to be just a soy sauce, quickly grabbed the monitor on his shoulder, but saw that the numbers on the reading screen did not turn into a striking red color.
"It's not nuclear contamination, and there is no part involved in this mission that involves nuclear biochemistry."
He quickly slides the data page to calm everyone's concerns:
"It should be some kind of low radioactive isotope. The decay signal...the specific function is not very clear, but it must be safe in any case." Wang Hongrang's Adam's apple moved. This is not in the test briefing he got, but now he can't care about so much.
The underground situation is still time to study, and the most urgent task now is to disguise the hit mark as a conventional ground-boring bullet.
"Determine the stability of the surrounding formation with the fastest speed, and then let the construction machinery enter!"
He pressed the encrypted communication key on the side of the helmet:
"We have a four-hour window."
When the horizon in the distance turned white, he finally heard the roar of the crawler excavator.
Three fast engineering vehicles dressed in desert camouflage are rolling over the saline-alkali land and slowly towards them.
Ai Xiaofeng watched the engineer start spraying silicate powder. These materials will form abnormal bulges around the crater, forging traces of ordinary ground-boring bombs that penetrate and explode.
Far further away, the antennas of the electromagnetic prism system are injecting interference signals into the atmospheric ionosphere, ensuring that any synthetic aperture radar sees a carefully calculated artifact.
But they can't work forever. "Is it necessary to do this?"
Ai Xiaofeng rubbed the reinforced concrete fragments at the edge of the crater, those hexagonal honeycomb structures that should have resisted the impact of nuclear explosions. It's like a wafer biscuit crushed by a child.
"The superiors still hope that the public appearance of this weapon will be a bit sudden and used to deter the new White House leader next year... and of course there are others who are ready to move."
Wang Hong asked to check the latest work of the ground penetrating radar and replied: "You also know that the ground testing of stealth fighter jets has been circulated through many channels. I want to maintain strict confidentiality around the city. It was still too difficult anyway. "
The loud noise and vibration of the crawler roller when it started working made Ai Xiaofeng almost stagger.
He held the radar bracket next to him and saw that the thermal imaging camouflage net had covered half of the target area.
These smart fabrics with miniature thermocouples are accurately reproducing the thermal residual signal from a regular ground boom test a few months ago. "In other words, is it possible for this kind of thing to participate in next year's National Day military parade?"
The first ray of sunlight really shone on the edge of the crater, and Wang Hongrang finally took off his protective helmet.
The morning breeze with the smell of nitrite swept across the gray hair in his ears, and the engineers in the distance were forging the fragments of the bullet with a laser sinter.
"This is not something I can know..."
