Chapter 572 U2 falls! ! ! ! (Part 2)
"."
In the combat center.
As the liaison officer's words rang out.
The entire tent instantly became audible.
But soon.
Li Jue clapped his hands excitedly and took the lead in breaking the silence:
"Great, these thieves are finally here!"
Li Jue's slap was like a start switch, making the atmosphere at the scene immediately lively again:
"Yeah!"
"Yes, but now that TMD is here, I haven't had a good sleep these days!"
"You should be able to beat it in this chapter"
"What a fool, kill these **************** turtles and grandsons!!!"
"Second Battalion Commander, where is your damn Zai Pelli Ao cannon?! Pull it out and prepare it!"
Lao Guo on the other side seemed relatively calm.
I saw him touching his chin, pondering for a moment, and analyzed:
"Oh? Is it a straight line? Is it Route 1?"
"It seems that our plan is indeed not revealed, or those U2s are still very confident in themselves."
"Otherwise, if they were a little wary, they wouldn't fly over so arrogantly."
"Hey, after all, people fly high, so that's understandable."
Master Qian shook his head slightly, looked around with an emotional expression, and said:
"But being behind now does not mean that we will always be behind. Maybe in a few decades, we will be in full opposition to superpowers in the field of armaments?"
"For example, aircraft, and radio - if the leader on the other side wants to reward the troops through the radio, but our radio is connected to the call during the call, and he is greeted by the sentence "This is the Chinese Air Force, the picture should be very interesting."
Hear this.
Lao Guo was slightly startled, then recovered and laughed:
".Aha, that's really interesting."
After a while.
Lao Guo suddenly thought of something again, his expression straightened, and he said to Qian Wushi and others:
"By the way, Lao Qian, is the Zhuxian Platform now in the air?"
Qian Wushi nodded without hesitation and pointed to the door:
"Of course, you were already in the air when you went to find Comrade Han Li - the airship has been on standby these days and can be put into combat at any time."
"The operation console is on the other side of the tent, so I guess you didn't notice it when you came - Comrade Baozheng and the others are in charge of this."
Lao Guo was slightly relieved.
Mentioned earlier.
The airship's ascent height is 5 meters per second, about 300 meters per minute, and the fastest is about 400 meters.
In other words.
It would take at least two hours to reach an altitude of 40,000 meters.
Therefore, the airship must start immediately as soon as it receives the information, so that the subsequent calibration time is taken into account in order to catch up with the last meal.
Then Lao Guo took Xu Yun out of the tent and came to the operating table of the weather Doppler radar.
Sure enough.
At this moment.
Baozheng had already led Lin Yu and others to the operating platform and began to observe the lift-off status of the Zhuxian platform.
Upon seeing this, Lao Guo quickly walked to Baozheng and asked him:
"Xiaobao, what's the height of the airship?"
Baozheng glanced at the screen in front of him and quickly reported a number:
"11451.4 meters, this is the data updated thirty seconds ago."
"In order to avoid the impact of radio on the airship as much as possible, we did not use the update frequency of every five seconds during the experiment this time."
"After all, in theory, although this frequency will not have a significant impact on the airship, it can even be said to have no impact at all, but stability is the priority in everything."
Lao Guo nodded in agreement.
Perhaps it is due to the stable genes hidden in the blood of the Chinese nation.
Rabbits will pursue absolute stability in almost all projects, even exaggerating to an almost metaphysical level.
For example, an airship ascends to the sky.
Normal situation.
Even if the electromagnetic waves in different bands are placed on Andromeda, they will not interfere with the airship, even if it is coupled interference.
But whether it was Qian Wushi or Sun Junren, they still chose to reduce the update frequency.
The reason is just four words:
Afraid of accidents.
Actually.
The base's means of stabilizing pressure at this time is far more than just an update frequency.
If you look further away.
You will also find that many places in the base are still being 'skinned' as usual before U2 arrives:
This is because in case the missile launch fails, the true identity of the 221 base must not be revealed.
no way.
The last guy who said that I had the advantage was already on the other side of the river.
Considering the possibility of failure in everything, this is not pessimism, but a sign of stability.
The same is true for Xu Yun in later generations.
When he was writing the book "The Empire of Technology Begins with the Elimination of Cockroaches", he had already thought of the ending of the next book and the beginning of the next book
that's all.
With everyone's attention, time passed slowly minute by minute.
The height of the airship is also getting higher and higher.
All around the operating table, only Baozheng's voice sounded every half a minute:
"Height 15,367 meters! Offset 0.14%! Main and auxiliary cabin pressure ratio 0.93! Upper stress shear coefficient 2.31!"
"Height 26899 meters, offset 0.15%! Main and auxiliary cabin pressure ratio 0.93! Upper stress shear force coefficient 2.31!"
"Height 34,452 meters, offset 0.17%! Main and auxiliary cabin pressure ratio 0.95! Upper stress shear force coefficient 2.32!"
Xu Yun noticed.
For the same parameters, the accuracy reported by Baozheng this time was much higher than that on the day of the experiment.
It's obvious.
During this time, Mr. Wang and the others made another optimization for the airship.
How dare you do this at such a critical moment
Artists are bold
An hour and a half later.
Baozheng's voice suddenly rose a little higher:
"Report, the airship has arrived at the preset location, and the current altitude is 40,281 meters!"
"After radio calibration, all module parameters are normal!"
Hear this.
The atmosphere at the scene finally became a little more relaxed.
Of course.
Just a little.
After all, the most critical part of ‘Zhu Xian’ has not been completed yet.
After a while.
Wow——
The tent in the combat center was suddenly opened from the inside, and Yu Da came out holding a few pieces of paper.
I saw him quickly coming to Lao Guo and talking to him in a low voice.
Lao Guo raised his eyebrows when he heard this, took the calculation paper and looked at it for a while, then nodded approvingly.
Then he turned back to Xu Yun's wheelchair, patted the back of the wheelchair, and said to Xu Yun:
"Comrade Han Li, get ready, we will set off in three minutes."
"Let's go?"
Xu Yun was slightly startled and asked subconsciously:
"Director Guo, U2 will be arriving in an hour or two. Where are we going now?"
Lao Guo still held the back of the wheelchair with both hands, thought for a moment, and explained:
"Comrade Han Li, you have studied abroad, you should have seen an opera performance, right?"
Xu Yun was a little confused, but he nodded slightly:
"Seen it."
Forget about the opera performance.
In later generations, he even spent RMB 500 to go to Wu Bai's concert and sang Wu Bai's songs to Wu Bai live.
Then Lao Guo drew a schematic diagram of an area in the air with his hand and said:
"Then you should know that opera performances charge different ticket prices based on location, such as private rooms, back rows, front rows, etc."
"If we use an opera as an analogy, our base here is at most in the middle, maybe even a little further back - after all, it is impossible for the plane to explode when it passes directly over the base, that would be too dangerous."
"And where we are going now is the front row, which is where U2 will fall."
Xu Yun:
"????"
Immediately afterwards.
He suddenly realized something.
He suddenly turned his head and looked at Da Da on the side.
Da Ze scratched his head shyly and explained with a smile:
"Comrade Han Li, haven't we already preliminary grasped U2's flight path in the past hour? It's basically the same as before."
"So I made a simple summary based on the data sent back by the J-5 fighter jets, and then made a calculation based on the movement trajectories of the waveriders of our four Zhuxianjian missiles."
"Finally, a model was built to find a point where theoretically three fighter jets could be seen falling at the same time."
"It's a small skill, it's not worth mentioning. All you need is your hands."
Xu Yun:
"."
After a while.
He suddenly sighed quietly:
"Made, there is a hook"
As everyone knows.
in missile science.
When the target flight data and missile parameters are known, it is not particularly difficult to calculate the location where the object fell.
That is, the speed of the missile, the initial position of the target and missile, the speed of the target and the time when it was shot down are known.
Combine these parameters with the speed of the missile and the position at launch to establish a system of equations, and solve the system of equations to obtain the length of the missile's motion curve.
Then the velocity (v1, v2) and acceleration (a1, a2) of the missile in the vertical and horizontal ground directions can be calculated to calculate the target's position when it was shot down.
Finally, by combining the target's flight speed with the collision angle, we can deduce the location where the target fell - this collision magnitude does not need to consider air resistance.
This calculation process is not to mention super calculated.
In the future of 2023, some big guys can really rely on written calculations and mental calculations to arrive at results.
But the premise of the above sentence is
Missiles are ordinary missiles.
Things like waveriders
Put it this way.
Let’s not talk about missiles, which are easily reported, but about aircraft.
The landing area of an ordinary Shenzhou series aircraft when returning to Earth is generally about 1,200 square kilometers.
That is to say, the returner will probably fall at any point within this range.
And what about the Chang'e-5 spacecraft that uses waverider technology?
The estimated land area when it returns to Earth is
20,000 square kilometers.
That's right.
Twenty thousand kilometers.
It is 16 times that of the Shenzhou series.
To know.
This is the accuracy achieved by the top supercomputing simulations of rabbits in later generations.
Suddenly.
Without warning, a once-famous sentence on a military fan forum emerged in Xu Yun's mind:
No one in the world can calculate the ballistics of Qian 5th Division, unless he is called.
Yu Min.
to be honest.
This sentence was actually quite controversial in later generations.
But Xu Yun didn't expect that in this copy, he would actually witness this answer with his own eyes.
At the scene, it was true, I was the wheelchair.JPG.
A few minutes later.
Lao Guo, Qian Wushi, Xu Yun and others who were ready got into three jeeps one after another and began to drive toward the landing point calculated by Yu Min.
Of course.
The number of people in the on-site tour group this time was not very large, and they were basically all relevant persons in charge who had no command tasks or technical support.
Radio experts like Sun Junren and base leaders like Li Jue naturally have to stay in the base at this time.
Other than that.
Accompanying Lao Guo and the others were two security squads, mainly responsible for security work.
Although the probability of an accident is very low, rabbits will never allow such a risk to exist - after all, who knows if there are any wild boars and wolves in the wild?
More than fifty minutes later.
Thorny——
The jeep stopped steadily beside a mountain col.
This is the shady side of a hillside about fifty meters high. There are no trees around, only a few short weeds.
The ground was hard, dry soil that seemed to have been dried by the sun.
After parking the car.
The security team quickly got out of the car and started to be vigilant.
Some soldiers suddenly and silently found a stone, and disappeared behind the stone as if wearing an invisibility cloak.
Some soldiers quickly occupied a certain high point to ensure the broadest view.
Other soldiers moved down a telegraph machine and began to communicate with the base.
"Everyone, we left the base at 10:12 in the morning, and it is now 11:05."
Lao Guo turned over his wrist, glanced at the display on his watch, and said:
"According to U2's flight speed, which is 700 kilometers per hour, it should pass over the base in more than half an hour."
Hear this.
Everyone also nodded solemnly.
In about half an hour, the results of this exam will be released.
And it’s different from the percentage system.
There are only two results for this exam:
Shoot down three U2s, full score.
If you lose any one or more, you will fail the test directly.
At this moment.
Xu Yun's mood was also restless.
It's a coincidence.
When he was writing novels in his previous life, he also wrote a plot in which three U2s flew to the mainland.
At that time, a reader once said:
[Nonsense, how could there be three reconnaissance planes flying to the same place at the same time? Who has done such a thing since ancient times? 】
first.
The first airplane in human history appeared in 1903. The history of airplanes is as short as that of a country across the sea. How can we talk about ancient times?
Secondly.
Not to mention how many times London was surveyed by reconnaissance planes during World War II. Let’s take a look at some recent examples.
May 14, 2020.
Mao's Kaliningrad was scouted by two E-3ASentryAWACS and a BeechcraftRC-12XGuardrail for four hours at the same time. The distance between them was only 200 meters apart.
And the U2 reconnaissance aircraft itself.
in the original history.
Now, two years after this period, on July 12, three U2s set off at the same time to conduct a reconnaissance of the Fengman Power Plant.
At that time, the other side thought that the Fengman Power Plant was actually a secret base for enriching uranium, so they immediately dispatched three U2s at the same time.
Although the rabbits at that time had the ability to shoot down U2, the actual success rate was not that high. U2 would still perform more than ten missions a year.
This incident was recorded in the county annals of Junbo and Jiangcheng City. The original description is:
[Three U2 reconnaissance planes flew over the power plant three minutes and four minutes apart respectively].
So the whole question above is wrong. (I don’t know why, but every time I write about military affairs, a bunch of people come out to criticize me. I welcome corrections on some parameters and theoretical errors. I have corrected many mistakes in the past, but don’t take it for granted. Okay)
His eyes returned to reality.
After arriving at this hillside.
Everyone waited patiently.
at the same time.
The radio station is also constantly reporting relevant information about U2:
"U2 has entered the weather Doppler radar monitoring range, with speeds of 724 km/h, 727 km/h, and 722 km/h!"
"The three U2s are about two kilometers apart. One is in the lead, and the other two are on the flanks. The three are flying in a △ pattern!"
"The three U2s are currently 372 kilometers away from the attack point and are expected to arrive in about thirty minutes!"
At this moment.
Whether it's a hillside or a 221 base.
Between two o'clock, only Baozheng's clear voice continued to sound:
"322 kilometers!"
“279 kilometers!”
“241 kilometers!”
“188 kilometers!”
“126 kilometers!”
“70 kilometers!!!”
When the count comes to within 100 kilometers.
Bang bang bang——
Xu Yun suddenly heard his violent heartbeat.
However, he didn't seem to care, just staring in the southeast direction.
"50 kilometers!"
“33 kilometers!”
Suddenly.
Mr. Wang, who was looking into the distance with a telescope, suddenly took a deep breath and said in a deep voice:
"Coming!"
Swish——
In an instant.
Everyone raised their telescopes.
Sure enough.
I only see this moment.
Somewhere to the southeast of the crowd, three black planes suddenly appeared.
From a height perspective, they are about 15,000 meters.
At the same time.
Baozheng’s voice still continues:
“27 kilometers!”
"24 kilometers!"
“20 kilometers!!!”
The moment Baozheng said the word 20 kilometers.
Wang Lao, Qian Wushi, Yu Min, and Xu Yun almost shouted in unison:
"Launch!!!"
at the same time.
Inside the 221 base.
Qian Bingqiong and Li Jue also ordered together:
"Launch!"
Pat-
Liu Guangrong, then the head of the base garrison, heard this and pressed a certain launch button without hesitation.
Phew——
A certain launch command, together with the characteristic parameters of the three aircraft, were sent from the radar antenna and instantly transmitted to the Zhuxian Sword Array platform at an altitude of 40,000 meters.
Ka——
After receiving radio instructions.
The metal fasteners controlling the missile were loosened.
Bang.
The 50-gram detonating charge in the first stage inside the missile exploded instantly, giving the Zhuxianjian missile, which already had a certain inclination, a little horizontal kinetic energy.
Then under the influence of gravity.
The missile began to fall diagonally downward.
Normally.
The detonating charge of this amount is very small and can only allow the missile to glide for a period of time.
Soon it will lose horizontal speed, start to fall freely, and finally fall to the ground with a thud.
But
This missile is different.
With a waverider structure, it formed a shock wave that remained in the body 7 seconds after it fell.
Whenever the missile is about to become a free fall.
The shock wave will be like a spring, gently flicking the missile to the right when it is about to be stretched straight.
that's all.
The missile floated slowly in the air, and abruptly drew an image of the inverse proportional function of K>0 in the first quadrant in the air.
at the same time.
After receiving the characteristic values transmitted with the radio, the three missiles quickly divided into three directions during their fall.
True.
At an altitude of tens of thousands of meters, it is impossible for them to lock on the target's location from the beginning. This is simply unrealistic.
But
The location where they landed in advance happened to be on the path that the three planes must pass.
As long as the two parties are close to a certain distance, these three missiles can accurately lock on their partners.
Thirty-eight thousand meters.
Thirty-two thousand meters.
Twenty-four thousand meters.
Nineteen thousand meters
at the same time.
Li Nanping, who was taking photos of Base 221, suddenly felt an indescribable sense of crisis in his heart.
This is a unique instinct possessed by an old pilot, derived from the experience of war.
This instinct is hard to explain scientifically, but it does exist.
Li Nanping relied on it to avoid certain death four times.
Could it be that there are fighter jets appearing around?
Li Nanping first quickly glanced at the airborne radar, and after finding that there was nothing above, he decided to trust his sixth sense.
So
A second passed.
He then started to lift up to the flying height with all his strength.
Although the vertical capability of the U2 is not as good as the MiG series, it is a reconnaissance aircraft developed for reconnaissance after all, and its life-saving ability is unquestionable.
So it's quick.
The height of U2 rose straight up to nearly two thousand meters.
See this situation.
While Li Nanping breathed a sigh of relief, he also began to have enough energy to observe the situation outside the window.
But what made him frown was.
At this time, there were neither fighter jets nor fire control radar vehicles in the surrounding high altitudes.
Could it be
Is it really my own misjudgment?
Just when Li Nanping was hesitating whether to descend back to the original height.
Somewhere high in front of him.
A white smoke trail suddenly appeared in the high sky where there was no sign or any obstruction by clouds and fog.
Like.
Missile tail flame? !
Just for a second when Li Nanping was slightly lost in thought.
On both sides of the first tail flame, two similar lines of white smoke suddenly appeared.
Judging from the targets they attack.
It seems
It was the three U2s of myself and the captain!
Is this a missile?
That's not right.
How could any missile fall from the sky?
Moreover, the fire control radar did not respond before. More importantly, the tail flame did not appear until now?
Of course.
This thought was fleeting, after all, this was not the time to think about this.
After coming back to his senses.
Li Nanping's first reaction was
Stretch further!
After all, no matter where these three missiles appeared from, at least their trajectory must follow the basic laws of physics.
That is to say, as long as you avoid the most basic landing points, the missiles will not threaten your safety.
Think of this.
Li Nanping suddenly felt extremely grateful for his decision to take off early.
He looked pityingly at the two captains below and shook his head slightly.
Sure enough.
Lu Xiliang and Yang Shiju below quickly noticed the oncoming missiles, and the aircraft began to take off at the same time.
But due to location issues.
No matter how high they increased, they seemed to be within the missile's hit range.
See this situation.
Li Nanping couldn't help but raise his eyebrows and sighed to himself:
Captain, I will burn incense for you today next year. Leave your sister-in-law to me to take care of you. You can go with peace of mind
There is no doubt about it.
The hands of the rabbits today are obviously some unknown new technology.
Although he lost two U2s, the information he brought back was enough to avoid punishment and get promoted.
And just when Li Nanping had this idea in his mind.
Not far away.
The missile that seemed to be about to miss his position suddenly heard two subtle buzzing sounds on its warhead.
Immediately afterwards.
The missile's air rudder clicked to change the injection angle, and at the same time, the second stage, which was the propellant occupying 80% of the volume of the combustion chamber, began to burn violently.
Within one second.
The missile suddenly drew a beautiful arc in the air, abruptly changing its original flight course.
It cut through the sky like a golden lightning, and instantly turned into a long line of fire, heading straight for Li Nanping!
The air was instantly torn apart by violent explosions, and the roar that filled the sky seemed to tear the entire sky into pieces.
See this situation.
Li Nanping's pupils suddenly shrank.
Subconsciously, I wanted to twist the handle of the ejection skydiving.
Click——
The handle made a crisp sound, however.
The seat didn't move at all.
Click, click——
Li Nanping dragged it twice more, but the seat still didn't respond.
Suddenly.
In Li Nanping's mind, the figures of foreigners who checked the status of fighter jets before each departure appeared.
Think of this.
Li Nanping couldn't help but his eyes were splitting, and he roared:
"Johnson, I'm so stupid!!!"
The next moment.
Accompanied by a loud bang.
The missile accurately hit the U2 fuel tank, and the huge U2 reconnaissance aircraft was instantly blown to pieces.
Debris fell like raindrops, amidst the bloody storm
There was dead silence.
at the same time.
On the hillside.
Look at the three groups of fire appearing in the sky above your head.
Everyone at the scene was silent at first, and they were all in a daze.
But soon.
Lao Guo took off his hat and threw it heavily into the sky:
"Three U2s, not one missing!!! Success! We succeeded-!!"
"From now on, no one can come to our house in a big way. Long live the Republic!!!"
