Chapter 572: U2 fell! ! ! ! (Down)

Chapter 572 U2 Falls! ! (Down)

“.”

In the combat center.

Following the words of the liaison officer.

The entire tent instantly became the smell of needles falling.

But soon.

Li Jue clapped his hands excitedly, breaking the silence first:

"Great, these sun thieves are finally here!"

Li Jue's slap was like a start switch, and the atmosphere on the scene immediately became lively again:

"Great!"

"Yeah, but tmd is here, I haven't slept well these days!"

"It should be possible to finish this chapter"

"It's numb, kill this group of **** grandchildren!!"

"Second Battalion Commander, where's your **** Pelio Cannon?! Pull it out and prepare it!"

On the other side, Lao Guo seemed relatively calmer.

He touched his chin, pondered for a moment, and analyzed:

"Oh? It's a straight line? That's route one?"

"It seems that our plan is indeed not revealed, or those U2s are still very confident in themselves."

"Otherwise, as long as they are a little bit on guard, they won't be able to fly over like this swaggeringly."

"Hey, after all, they fly high, which is understandable."

Fifth Master Qian shook his head slightly, looked around with emotion, and said:

"But being behind now doesn't mean we will always be behind. Maybe in a few decades, we will overtake others in all aspects of armaments?"

"It's like an airplane, or a radio—if the leader on the other side wants to use the radio to reward the army, but our radio is connected to it during the call, the head-on will say that this is the Huaxia Air Force, and the picture should be very interesting."

Hear this statement.

Lao Guo was startled for a moment, then laughed when he came back to his senses:

“.Aha, that’s really interesting.”

After a while.

Old Guo suddenly thought of something again, his expression straightened, and he said to Fifth Master Qian and the others:

"By the way, old Qian, is the Zhuxian platform lifted up now?"

Fifth Master Qian nodded without hesitation, and pointed outside the door:

"Of course, when you went to look for Comrade Han Li, it was already in the sky—the airship has been on standby these days, and it can be put into combat at any time."

"The console is on the other side of the tent, so I guess you didn't notice it when you came—Comrade Bao Zheng and the others are in charge of this."

Old Guo heaved a sigh of relief.

Mentioned earlier.

The ascent height of the airship is 5 meters per second, about 300 meters per minute, and the fastest is about 400 meters.

In other words.

It takes at least two hours to ascend to an altitude of 40,000 meters.

Therefore, the airship must be started as soon as it receives the information, so that the time-consuming follow-up calibration can be counted 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.

as expected.

Right now.

Bao Zheng had already brought Lin Yu and others to the console, and began to observe the lift-off status of the Zhuxian platform.

Seeing this, Lao Guo walked quickly to Bao Zheng's side, and asked him:

"Xiaobao, how high is the airship?"

Bao Zheng glanced at the screen in front of him, and quickly reported a number:

"11451.4 meters, this is the data updated 30 seconds ago."

"In order to avoid the influence of the radio on the airship as much as possible, we did not use the update frequency of once every five seconds during the experiment this time."

"After all, in theory, although this frequency will not have too obvious impact on the airship, it can even be said that it will not have any impact at all, but stability is the main thing in everything."

Old Guo nodded in agreement.

Perhaps it is due to the prudent gene hidden in the blood of the Huaxia nation.

Rabbits will pursue an absolute stability in almost all projects, even exaggerating to a point of almost metaphysics.

For example, the airship ascends to the sky.

normal circumstances.

Electromagnetic waves of different frequency bands are unlikely to interfere with the airship even if they are placed on Andromeda, even if it is coupling interference.

But whether it is Qian Wushi or Sun Junren, they still choose to reduce the update frequency.

The reason question is four words:

Fear of accidents.

Actually.

The base's stabilizing means at this time is far more than a simple update frequency.

If you look away a little bit.

Many parts of the base will also be found, and at this time they are still undergoing 'skinning' as usual before U2 arrives:

This is in consideration of the fact that if the missile launch fails, the true face of Base 221 must not be revealed.

no way.

The last guy who murmured that I had the advantage had already gone to the opposite bank by this time.

Thinking of failure in everything, this is not pessimism, but a steady performance.

It is the same with Xu Yun of later generations.

When he wrote the book "Empire of Science and Technology Begins with Elimination of Cockroaches", he already thought of the ending of the next book and the beginning of the next book

that's all.

Under the attention of everyone, the time passed slowly every minute and every second.

The height of the airship is getting higher and higher.

Around the entire operating table, only Bao Zheng's voice sounded every half a minute:

"The height is 15367 meters! The offset is 0.14%! The pressure ratio of the main and auxiliary compartments is 0.93! The upper shear force coefficient is 2.31!"

"The altitude is 26899 meters, the offset is 0.15%! The pressure ratio of the main and auxiliary cabins is 0.93! The upper shear force coefficient is 2.31!"

"The height is 34452 meters, the offset is 0.17%! The pressure ratio of the main and auxiliary compartments is 0.95! The upper shear force coefficient is 2.32!"

Xu Yun noticed.

For the same few parameters, the accuracy reported by Baozheng this time is much higher than that of the day of the experiment.

It is clear.

During this time, Mr. Wang and the others made another optimization for the airship.

How dare you do this at this juncture?

Artists are bold

An hour and a half later.

Bao Zheng's voice suddenly raised a bit:

"Report, the airship has arrived at the preset position, and the current lift-off altitude is 40281 meters!"

"After radio calibration, all the parameters of each module are normal!"

Hear this statement.

The atmosphere at the scene finally became a little more relaxed.

Of course.

Just a little.

After all, the most critical "Zhu Xian" has not been completed yet.

After a while.

Clah—

The tent in the combat center was suddenly lifted from the inside, and Da Da walked out with a few pieces of paper.

I saw him walking quickly to Lao Guo's side, and talked to him in a low voice.

Old 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 around and came to Xu Yun's wheelchair, patted the back of the wheelchair, and said to Xu Yun:

"Comrade Han Li, get ready, we will leave in three minutes."

"Set off?"

Xu Yun was startled slightly, and subconsciously asked:

"Director Guo, U2 will arrive in about an hour or two. Where are we going now?"

Old Guo still supported 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?"

Xu Yun was a little confused, but he nodded lightly:

"Seen."

Not to mention opera performances.

In later generations, he even spent five hundred to see Wu Bai's concert, and sang Wu Bai's songs live for Wu Bai to listen to.

Then Lao Guo drew a schematic diagram of the area with his hands in the air, and said:

"Then you should know that opera performances will charge different ticket prices according to the location, such as private room, back row, front row, etc."

"If we use an opera as an analogy, our base here is at most a middle position, and maybe even a little behind. After all, it is impossible to let the plane explode when it passes directly over the base. That would be too dangerous."

"And the place we are going now is the front row, which is where U2 will fall."

Xu Yun:

"?????"

Immediately after.

He suddenly realized something.

Suddenly turned his head and looked at the larger than that.

Greater Than scratched his head shyly, and explained with a smile:

"Comrade Han Li, haven't we already grasped the flight path of U2 in the past hour, and it is 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 trajectories of the waveriders of our four Jade Sword missiles."

"Finally, a model was established, and a theoretical point where three fighter jets could be seen falling at the same time was found."

"Small tricks are nothing, as long as you have hands."

Xu Yun:

“.”

After a while.

He suddenly sighed faintly:

"Mad, there is a hang"

Well known.

In missile science.

In the case of known target flight data and missile parameters, it is not particularly difficult to calculate the falling position of the object.

That is, the known missile speed, the initial position of the target and the missile, the speed of the target and the time when it was shot down.

Combine these parameters with the velocity of the missile and the position when it is launched into a system of equations, and solve the equations to obtain the length of the motion curve of the missile.

Then import the velocity (v1, v2) and acceleration (a1, a2) of the missile in the vertical and horizontal ground directions, and the position of the target when it is shot down can be calculated.

Finally, by combining the speed of the target with the angle of impact, the location where the target falls can be deduced—this level of collision does not need to consider air resistance.

This calculation process is not to mention super calculation.

In the future 2023, some bigwigs can really get the results by pen and mental calculation.

But the premise of the above sentence is that

Missiles are ordinary missiles.

Something like a waverider

Let's put it this way.

Let’s not talk about missiles, which are easy to report, let’s talk about aircraft.

The landing area of ordinary Shenzhou series aircraft when returning to the earth is generally about 1200 square kilometers.

That is, the returner will probably fall at any point in this range.

What about the Chang'e-5 spacecraft that uses waverider technology?

Its projected land area when it returns to Earth is

20,000 square kilometers.

Exactly.

20,000 kilometers.

It is 16 times as much as the Shenzhou series.

To know.

This is the accuracy of the rabbits' top supercomputer simulations gathered by later generations.

Suddenly.

In Xu Yun's mind, without warning, a sentence that was once famous on a military fan forum in later generations emerged:

No one in the world can calculate the ballistic of the fifth division of Qian unless he is called .

Yu Min.

to be honest.

The controversy of this sentence in later generations is actually quite big.

But Xu Yun didn't expect that in this copy, he actually witnessed the answer with his own eyes.

On the scene, it's true, I'm the wheelchair.JPG.

After a few minutes.

Old Guo, Qian Wushi, Xu Yun and others who were ready got into three jeeps one after another, and began to beeping towards the landing point calculated by Yu Min.

Of course.

The number of on-site sightseeing groups this time is not very large, and basically they are all relevant persons in charge who have 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.

Accompanied by Lao Guo and the others, there are two guard squads who are mainly responsible for security work.

Although the probability of accidents is very low, the rabbits will never allow this kind of risk to exist—after all, who knows if there are wild boars and wolves in the wild?

More than fifty minutes later.

Prick—

The jeep parked steadily beside a mountain depression.

This is a shady side of a small hillside about 50 meters high, with no trees around, only a few short weeds.

The earth is hard dry soil, which seems to have been dried by the sun.

After parking the car.

The security squad quickly got off the car and set up vigilance.

Some soldiers found a stone suddenly and silently, and disappeared behind the stone as if wearing an invisibility cloak.

Some fighters quickly occupy a certain high point, ensuring the widest view.

Some soldiers moved down a telegraph and began to communicate with the base.

"Everyone, we left the base at 10:12 in the morning, and it is now 11:05."

Old Guo turned his wrist, glanced at the indication of the 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 statement.

Everyone also nodded heavily.

In about half an hour, the results of this test will be released.

And different from the percentile system.

There are only two results for this exam:

Shoot down three U2s, full score.

Run away any one or more, directly fail.

Right now.

Xu Yun's mood was also restless.

Coincidentally.

When he was writing a novel in his previous life, he also wrote a plot of three U2s flying to the mainland.

At that time, a reader once said:

【Nonsense, how could three reconnaissance planes fly to one place at the same time? Since ancient times, who has done such a thing? 】

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 since ancient times?

Next.

Not to mention how many times London was sent to reconnaissance planes at the same time during World War II, let's give some modern examples.

May 14, 2020.

Da Mao’s Kaliningrad was reconnaissance by two E-3ASentryAWACS and a BeechcraftRC-12XGuardrail at the same time for four hours, and the distance between each other was only 200 meters.

And the U2 spy plane itself.

In the original history.

Now, on July 12, two years later, 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 carry out 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 at intervals of three minutes and four minutes respectively】.

So the entire text of the above question is wrong. (I don’t know why, every time I write about the military, a bunch of people come out to argue. I welcome corrections on some parameters and theoretical mistakes. I have also corrected a lot of mistakes before, but don’t say such things for granted. bar)

The line of sight returns to reality.

After arriving at this hillside.

Everyone waited patiently.

at the same time.

The radio station is also constantly reporting the relevant information of U2:

"U2 has entered the monitoring range of the weather Doppler radar, and the speeds are 724 km/h, 727 km/h, and 722 km/h!"

"The distance between the three U2s is about two kilometers, one is in the lead, the other two are on the flanks, and the three are flying in a △ shape!"

"The three U2s are currently 372 kilometers away from the attack point and are expected to arrive in about 30 minutes!"

Right now.

Whether it is a small hill or the 221 base.

Between two points, only Baozheng's clear voice continued to sound:

"322 kilometers!"

"279 kilometers!"

"241 kilometers!"

"188 kilometers!"

"126 kilometers!"

"70 kilometers!!"

When the count comes within 100 kilometers.

bang bang bang—

Xu Yun suddenly heard his own violent heartbeat.

But he didn't care about it, just staring at the southeast direction.

"50 kilometers!"

"33 kilometers!"

Suddenly.

Wang Lao who was looking into the distance with a telescope on his side suddenly took a deep breath, and said in a deep voice:

"coming!"

唰—

In an instant.

Everyone raised their binoculars.

as expected.

I saw this moment.

Somewhere to the southeast of everyone, three black planes suddenly appeared.

Judging from the height, they are about 15,000 meters away.

at the same time.

Bao Zheng’s voice continued:

"27 kilometers!"

"24 kilometers!"

"20 kilometers!!"

The moment Bao Zheng said the word 20 kilometers.

Old Wang, Fifth Master Qian, Yu Min, and Xu Yun shouted almost in unison:

"Launch!!"

at the same time.

In base 221.

Qian Bingqiong and Li Jue also ordered together:

"Launch!"

Pata—

When Liu Guangrong, who was in charge of the garrison at the base at the time, heard the words, he pressed a certain launch button without hesitation.

Whoosh—

A certain launch command, together with the characteristic parameters of the three aircrafts, were sent out from the radar antenna and transmitted to the Zhuxian Sword Array platform at an altitude of 40,000 meters in an instant.

ka—

After receiving radio instructions.

The metal fixture controlling the missile was loosened.

Boom.

The 50-gram primary explosive in the first stage of the missile exploded instantly, giving the Jade Sword missile, which already had a certain inclination angle, a little horizontal kinetic energy.

Then under the action of gravity.

The missile began to fall diagonally downward.

Normally.

The equivalent of the primary explosive is very small, and it can only allow the missile to glide for a period of time.

Soon it will lose its speed in the horizontal direction, start to fall freely, and finally land with a snap.

but

This missile is different.

Having a waverider structure, it formed a shock wave that did not come off the body in the 7th second after falling.

Whenever the missile is about to go into free fall.

The shock wave will be like a spring, flicking the missile that is about to be stretched straight to the right.

that's all.

The missile floated slowly in the air, forcibly drawing an image of an 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 the fall.

Indeed.

At an altitude of tens of thousands of meters, it is impossible for them to lock the position of the target from the beginning, which is simply unrealistic.

but

The place where they landed in advance happened to be on the only way the three planes had to pass.

As long as the two sides are close to a certain distance, the three missiles can accurately lock their partners.

Thirty-eight kilometers.

Thirty-two thousand meters.

24 thousand meters.

19 thousand kilometers

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 leaned on it, and had escaped death four times.

Could it be that there are fighter jets appearing around?

Li Nanping first glanced at the airborne radar quickly, and decided to trust his sixth sense after finding that there was nothing on it.

A second passed.

He began to pull up the flight altitude with all his strength.

Although the U2's vertical capability is not as good as that of the MiG series, it is a reconnaissance aircraft developed for reconnaissance after all, and its life-saving capability is beyond doubt.

So fast.

The height of U2 has risen straight up by nearly 2,000 meters.

See this scenario.

While Li Nanping breathed a sigh of relief, he also began to have the energy to observe the situation outside the window.

However, what made him frown was.

At this time, there were neither fighter jets nor fire control radar vehicles in the surrounding high altitude.

Murphy

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.

In the high sky, where there was no sign or the slightest cloud and fog, a white smoke trail suddenly appeared.

It's just like.

Missile tail flame? !

It was within a second that Li Nanping was in a trance.

On both sides of the first tail flame, two similar white smokes suddenly appeared.

Judging from the target of their attack.

seems

It is the three U2s of myself and the captain!

Is this a missile?

Not right.

Which missile fell from the sky?

And the fire control radar didn't respond before, and more importantly, the tail flame didn't appear until now?

Of course.

This thought is only fleeting, after all, right now is not the time to think about it.

After regaining consciousness.

Li Nanping's first reaction was

Re-stretch height!

After all, no matter where these three missiles appeared from, at least their trajectories must follow the basic laws of physics.

That is, as long as you avoid the most basic landing point, the missile will not threaten your safety.

Think here.

Li Nanping was suddenly very grateful for his decision to take off early.

I saw him look at the two captains below with pity, and shook his head slightly.

as expected.

Lu Xiliang and Yang Shiju below also noticed the oncoming missile soon, and the aircraft also started to lift off at the same time.

But due to location issues.

No matter how high they go, they seem to be within range of the missiles.

See this scenario.

Li Nanping couldn't help raising his eyebrows, and sighed secretly:

Captain, I will burn incense for you on this day next year. Let me take care of my sister-in-law. You can go with peace of mind.

no doubt.

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 this idea popped up in Li Nanping's mind.

not far away.

The missile that seemed to be about to pass by under him suddenly had two subtle buzzing sounds from the warhead.

Immediately after.

The air rudder of the missile clicked to change the injection angle, and at the same time the second stage. That is, the propellant that occupied 80% of the volume of the combustion chamber began to burn violently.

Within a second.

The missile suddenly crossed a graceful 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 a violent explosion, and the roar seemed to tear the entire sky into pieces.

See this scenario.

Li Nanping's pupils shrank suddenly.

Subconsciously, I wanted to twist the ejection skydiving handle.

click—

The handle made a crisp sound, however.

The seat did not move at all.

click, click—

Li Nanping dragged and tugged twice, but the seat still did not respond.
