I saw Li Jue's whole body "swish" and he suddenly stood up from behind his desk, staring intently at Qian Bingqiong in front of him.
In extreme shock.
He didn't even notice that the ink bottle in his hand was knocked over on the table:
"That medium rare... No, that Han Li said he could knock down U2?"
Qian Bingqiong first slowly straightened the ink bottle, then picked up a rag and wiped it, and then said:
"Yes, and I would like to add that Han Li's so-called taking down the U2 reconnaissance plane was not just as simple as shouting a few slogans."
"He not only gave some brand-new technical ideas, but also explained the general principles to me and Director Ye."
Say it.
Qian Bingqiong also introduced Xu Yun's ideas to Li Jue.
"...."
Li Jue was stunned for a while after hearing this, and he was still a little unbelievable:
"Build an airship to send artillery shells into the sky, use weather Doppler radar to detect the trajectory, and then use ultra-wideband proximity fuses to track the target..."
"This...what exactly is in Han Li's mind?"
Hear this.
Qian Bingqiong, who was sitting opposite Li Jue, couldn't help but nod.
Li Jue's last words actually represent Qian Bingqiong's inner thoughts.
How did Han Li's brain grow?
How did he come up with such an idea that was wild but seemed feasible?
If the concept of "brain hole" hadn't existed these days, Qian Bingqiong would probably complain that Xu Yun's brain hole was so big that it was like a hole in his neck.
At the same time, what makes Qian Bingqiong's mood slightly complicated is...
To know.
One of the purposes of his coming to Base 221 this time was to find an opportunity to observe Xu Yun's abilities as entrusted by Liu Bosheng.
So today after learning that Ye Duzheng wanted to talk to Xu Yun.
He then offered to go with Ye Duzheng as a boilermaker to visit this old acquaintance who was already well-known in the senior management.
The result was unexpected.
Xu Yun first exposed the mathematical fact that the world is nonlinear through communication with Ye Duzheng, and informed him that he should vigorously develop computers.
Then after U2 appeared, an even more shocking plan for shooting down the U2 reconnaissance plane was thrown out.
Really, if you look at it one more time, you will explode.
True.
At this point, the possibility of Xu Yun being an enemy agent can be completely ruled out.
After all, it is impossible for any enemy agent to use so many important technologies to make a name for himself, not to mention that many of these technologies are even better than the research and development progress across the sea.
But on the other hand.
The mystery surrounding Xu Yun has become even thicker...
No matter which angle you look at it.
The behemoth behind Xu Yun should be far more than just the so-called Fengling Yueying Sect.
After a while.
It was Li Jue who came to his senses first and said to Qian Bingqiong:
"Okay, Comrade Bingqiong, we might as well put Han Li's personal situation aside for now. The higher authorities will definitely take action in this regard."
"After all, there are problems that we are all aware of, and it is impossible for higher-level departments to not think of them - their channels are much more efficient than ours."
"So now let's talk about Han Li's plan first. Comrade Bingqiong, how feasible do you think his plan is?"
"If the feasibility is indeed high, then we should report it to the capital immediately."
"No matter where Han Li got his theory, as long as we can defeat U2, it won't be a loss for us!"
Qian Bingqiong obviously thought of this too.
I saw him thinking for a moment and then quickly said:
"Old Li, you should also know that the fall of a cannonball involves very complex ballistic calculations, which is not a problem that can be solved in an hour or two."
"Obviously, this link can only be solved after the project team is formally established, so what we can currently verify are mainly some links in non-mathematical fields."
Li Jue nodded in agreement.
Back then, he once went to a certain domestic missile research and development department and walked through the door. He felt blinded instantly after seeing the densely packed calculation papers.
This kind of calculation requires a lot of manpower and material resources, and is obviously not something that can be easily verified.
Then Qian Bingqiong paused and continued:
"Lao Li, I made a brief plan before. At present, there are three key technical level issues that we can verify and compare."
"They are the theoretical analysis of ultra-wideband proximity fuzes, the material issues of the airship capsule, and whether meteorological Doppler radar can detect the aircraft trajectory while changing the wave frequency."
"I have asked some comrades to lead a team to verify the theory of the ultra-wideband proximity fuze. As for the latter two, I need you, Lao Li, to coordinate."
Li Jue was suddenly startled:
"Am I going to show up?"
But he reacted immediately.
Too.
Qian Bingqiong is currently just an 'inspector' from the capital, and Li Jue himself must speak out about administrative matters within the base - this is a rule set by the base at the beginning of its establishment.
After realizing this, Li Jue stopped procrastinating.
I saw him immediately shouting outside the house:
"Xiao Zhou, come in!"
.........
Half an hour later.
The ninth branch of the base.
221 Base Chemical Laboratory.
The location of the chemical laboratory is located south of the ninth branch of the base, which is considered a relatively remote area - this is to prevent chemical accidents from causing too many secondary losses.
Its appearance looks like two ordinary workshops connected together, not even as conspicuous as Ye Duzheng's meteorological center.
But in fact.
This laboratory is responsible for the R&D and production of the base's main chemical materials, and is considered the core R&D center for the base's chemical products.
In a sense.
This laboratory is somewhat similar to the staff hospital at the base:
They are all unusual components of the base, but they are indispensable. At the same time, the internal equipment configuration is also very advanced.
Just like the staff hospital has X-ray machines, ECG monitors and returned overseas Chinese experts like Lin Yu.
The chemical laboratory also has a lot of advanced equipment, and the person responsible for these equipment and personnel management is Liu Youcheng, a senior expert who is also a national expert.
But at this moment.
This elder, later known as the founder of free radical chemistry in China, was looking at the assistant He Guozhong in front of him in surprise:
"Xiao He, what did you say?"
"Director Li wants us to mix local donkey epidermal mucus and benzoquinoline, and then let it stand to observe the subsequent phenomena?"
He Guozhong also scratched his head in confusion and answered honestly:
"Yes, this is the news personally sent by Comrade Zhou Cai, Director Li's assistant, and they hope that we can give a reply as soon as possible."
Liu Youcheng:
"...."
To be honest.
He suddenly felt like turning the table over.
To know.
He was depressed just now because the high-temperature silicone paint produced in his laboratory was affected by U2 and could not be applied in time to detonate the laboratory station and was forced to be scrapped.
As a result, a mysterious instruction suddenly came from the factory, asking them to study some local donkey mucus?
Moreover, the amount of mucus collected and tested is quite large, plus the manpower to prepare benzoquinoline...
This means that within a few hours, at least 80% of the members of the entire laboratory have to stop what they are doing.
Li Jue has had many interactions with Liu Youcheng, and he doesn't seem like someone with weird hobbies...
"...."
After a while.
Liu Youcheng rubbed his temples helplessly and sighed:
"Forget it, Xiao He, maybe the organization has some new plans, we can just cooperate."
"In this case, you go ahead and tell everyone to stop what they are doing."
"Comrades with odd-numbered work numbers are going to collect donkey epidermal mucus and gather downstairs. Comrades with even-numbered numbers are preparing benzoquinoline in the laboratory."
"In addition, Qiao Wei's group is not included. Their research project is very important. Don't let this matter affect their research."
He Guozhong's expression suddenly became serious:
"clear!"
ten minutes later.
Liu Youcheng led more than thirty gay men and women with different expressions in a grand manner out of the workshop and went straight to the donkey shed at the base.
There are seven donkey sheds in base 221 managed by the livestock sideline team.
Among them, the donkey shed closest to Liu Youcheng is located about two kilometers southeast of the laboratory.
When Liu Youcheng and everyone arrived at the donkey shed.
Gonpot, who was the captain of the base's livestock sideline team at the time, had been waiting here for a while.
Gonpot is one of the few ethnic minority members in the base and an aborigine of the Jinyintan Grassland. He was appointed deputy captain of the Haiyan County Animal Husbandry Brigade a long time ago.
After his fellow tribesmen all moved away from the Jinyintan grassland.
Gonpot and his wife, who were experienced in animal husbandry, stayed here under the persuasion of the organization and took charge of matters related to the base's animal husbandry sideline business.
In the days when resources are most scarce.
It was Kampot and the others who took care of the cattle and sheep of the livestock team day and night, so that the workers at the base could occasionally taste some meat.
"Comrade Kampot, I'm sorry to keep you waiting."
After arriving at the donkey shed.
Liu Youcheng immediately stepped forward to shake Gonpot's hand and said apologetically:
"We encountered a strong burst of sand and dust on the way here, so we took shelter from the gust of wind on the roadside, so we arrived a little late."
Gongpo's face had a blush common among Tibetans. He was short, dark-skinned, and looked honest and simple.
Hearing this, he quickly smiled, waved his hand, and said in slightly jerky Chinese:
"It's okay, it's okay, don't take it to heart."
Say it.
Gongbu turned around again, pointed to the donkey shed behind him and said to Liu Youcheng:
"Director Liu, the organization has informed me in advance that I have already arrived at the donkey shed for the donkeys you want."
"There are a total of twenty-four donkeys in the donkey shed, and each donkey is tied to a separate slot. You can do whatever you want to do boldly."
Upon hearing this, Liu Youcheng thanked Gongpo and then followed him to the donkey shed.
As Kampot said.
These donkeys have been carefully tied in the shed by Gongfu at intervals with notches, and there is a fence between each donkey.
The fence blocks the donkey's view, making it easier to operate.
After entering the donkey shed.
Liu Youcheng glanced around the shed subconsciously, and suddenly stopped at the far left corner of the donkey shed, pointing to the location and asking:
"Comrade Kampot, what's going on with that donkey over there?"
Kampot took advantage of the situation and looked around.
I saw a strong local donkey tied to the position pointed by Liu Youcheng.
If donkeys also have good looks, Liu Youcheng feels that this donkey can be called Wang Xingang among donkeys.
But what attracted Liu Youcheng was not the appearance of the donkey, but because...
Many areas on this donkey's body are covered in large patches of bald spots, as if someone had neatly picked it up several times.
"Oh, ask this donkey."
Gonbu smiled upon seeing this, put his hands behind his back like a little old man, and explained:
"This is a donkey brought by a comrade named Xie Yu in the base from his hometown of Zhenjiang. I heard that their ancestors served some high official, and this donkey is the breed left by that high official. It is much stronger than ordinary donkeys.
"
"It turns out that some foreign student came to the hospital at the base some time ago with an injury. Rumor has it that his surname is Niu, and his name is steak. His usual taste is very strange."
"It is said that he eats with donkey hairs every meal, and he has to stuff a few donkey hairs into his mouth to eat a piece of cornbread, so the hospital has to send someone to knead the donkey hairs every day."
"After coming and going again, this donkey is like this."
Liu Youcheng:
"...."
have to.
Weird things happen every year, but today there are especially many.
However, this surprise was fleeting, and Liu Youcheng quickly turned his mind to business.
He took a deep breath and greeted the people around him:
"Comrades, let's start working!"
Liu Youcheng just finished speaking.
The laboratory members behind him divided into groups of three according to the predetermined rules and walked towards the donkey shed.
The local donkeys in the donkey shed have become docile donkeys after a long period of domestication, and they are not afraid when they see Liu Youcheng and others approaching.
There was even a donkey saying hello.
After arriving at the donkey trough.
Each group first selected the donkeys in turn, and then...
I took out the razor and started shaving.
no way.
This time Liu Youcheng and his colleagues aimed to collect 300 ml of apical secretion, which is about the size of a bottle of Jiaduobao in later generations.
If you want to collect mucus, you obviously have to shave off all the donkey hair first.
So it's very fast.
Donkey sounds of various tones rang out in the donkey shed:
"Ohhhhh——"
"Uh-huh-huh-"
"Amiya——"
...........
Not long after Liu Youcheng and others scraped donkey hair to collect mucus.
The hinterland of the Badain Jaran Desert.
Qingshui Base 14.
A J-6A...or a fighter jet that should be called Dongfeng 103 in this era also quietly flew high into the sky from the base.
The J-6A is a copycat of Mao Xiong’s MiG-19 fighter, and it is also the first supersonic fighter developed by China.
Although according to the historical trajectory.
The current J-6A has only completed test flights and identification and acceptance, and will not be officially put into production in a few years.
However, as the first experimental training base of the Chinese Air Force, Qingshui 14 still has several basic J-6A aircraft.
At this moment.
The pilot of this J-6A, Chen Pingsheng, was skillfully operating the fighter jet to slide out of the runway, while at the same time transferring data with the tower:
"Dongguai Dongguai, what is your fuel status? Please report it."
"Status 4.5, no overload."
"Received, received, is the radar status normal?"
Chen Pingsheng glanced at the detection radar panel on the dashboard:
"No abnormalities in dual bands, received signal code 5674,,."
"The parameters are normal and the airspace status is normal. You can fly up. I wish you a smooth mission."
"Thanks."
After hanging up the communication.
Chen Pingsheng pulled the joystick.
On the other hand, he glanced at the tower on the ground with some confusion.
half an hour ago.
The political commissar of the base suddenly found Chen Pingsheng and informed him that he had a flight mission to complete.
Although in the original plan, there was no flight plan for the base today.
But in Chen Pingsheng's twelve years of flying career, such sudden accidents were not uncommon.
So he wasn't too surprised at first.
But the following instructions from the political commissar left him a little confused:
The base required him to drive the Dongfeng 103 to "circle around" the West China Sea area, turning on the fire control detection radar throughout the process, but there was no interception target or test flight target.
The only requirement is that after the fire control detection radar is sensed, it immediately contacts a radio receiving point in a special band.
And report [detection radar has detected fire control lock], and then return.
It can be said like this.
Chen Pingsheng has never encountered such a weird instruction since he first got on the plane.
But as the saying goes.
It is the duty of soldiers to obey orders.
Therefore, although there were some doubts in his heart, Chen Pingsheng immediately carried out the order.
So this flight took place.
The Badain Jaran Desert is the third largest desert in China, and the straight-line distance to the border of Xihai Province is about 800 kilometers.
The flight range of the J-6 is 1,690 kilometers, which is a bit difficult to fly.
However, Chen Pingsheng’s J-6 today does not carry weapons, and is also equipped with a 760-liter auxiliary fuel tank, so the actual flight range can reach 2,200 kilometers.
This is actually nothing.
Wait a few more years.
The rabbits will also modify this thing into a version that can carry two auxiliary fuel tanks...
And just when Chen Pingsheng was flying at a speed of about 700 kilometers per hour as required.
Base 221 hundreds of kilometers away.
Ye Duzheng and Sun Junren were standing next to the weather Doppler radar at the base, looking at the screen in front of them solemnly.
Not long ago.
After discussion between Li Juezai and Qian Bingqiong.
We decided to conduct an internal test of the ‘hardware’ part of Xu Yun’s plan first.
That is to check the authenticity of the two most basic steps: donkey mucus and detection track.
If any one of these two links goes wrong.
Then Xu Yun's plan has no practical feasibility.
Among them, the local donkey mucus is relatively simple, but the radar detection track is relatively complicated.
Of course.
It's just relatively complicated.
After all, although the rabbits cannot arrange for U2 to fly to Xihai Province immediately, it is not difficult to reproduce the preset situation of U2:
Just find a fighter jet that can also detect fire control radar signals.
After all, the essence of Xu Yun's plan is to completely scan the aircraft's flight trajectory without revealing the fire control radar band.
As for airborne radar that can detect fire control radar signals, rabbits these days...or in other words, there is basically no shortage of several major powers in the world - this is a technology that existed at the end of World War II.
After all, there is nothing special about this type of detection radar itself. They only need to detect special wave bands such as three millimeter waves.
Therefore, under the coordination of Li Jue.
Qingshui Base 14 immediately dispatched a J-6A fighter jet to cooperate with the base's operations.
A few minutes passed.
Lin Yu, Sun Junren's student, walked quickly to his side.
Lin Yu first glanced at Ye Duzheng, and then said to the two of them:
"Yuan Sun, we just received news from the main factory, saying that Director Liu Youcheng and his colleagues have completed the mucus standing experiment."
"After preliminary testing, the donkey's apical secretion fluid and benzoquinoline can indeed form a highly malleable colloid, which should theoretically meet the requirements for an airship's capsule."
"..."
After hearing what Lin Yu said.
Sun Junren couldn't help turning his head and looked at Ye Duzheng. They both saw the excitement and...
dignified.
I'm excited because with the release of Liu Youcheng's results, the feasibility of Xu Yun's plan has increased by one point.
Dignity is because...
Today, the pressure is completely tilted towards detecting the trajectory of fighter jets.
If the radar detection is successful.
This means that there are no obvious technical difficulties in terms of technology except for artillery shells.
But if the test fails...
That means all previous efforts will be in vain:
Everyone was so excited, the plane took off in vain, and the donkey's hair was plucked in vain.
And when Sun Junren and Ye Duzheng were silent.
In a tent not far away.
A liaison officer from the Secrecy Front suddenly poked his head out of the tent and said:
"Director Ye, Academician Sun."
"According to the radio information just received, the straight-line distance between the target fighter and the base is within 500 kilometers!"
Swish——
The liaison officer just finished speaking.
Ye Duzheng and Sun Junren turned their heads at the same time and said in unison to Bao Zheng at the operating table:
"Xiaobao, turn on the phone quickly!"
heard this instruction.
Baozheng immediately pressed a button.
After a while.
stop--
The weather Doppler radar, which had been reassembled after U2 passed through, made a startup sound again.
But it's different from usual.
This time, the wave frequency emitted by this meteorological Doppler radar is relatively longer...
l band.
As we all know.
in the radar industry.
The radar operating frequency is divided into several bands, and the order from low to high is:
High frequency (hf), very high frequency (vhf), ultra high frequency (uhf, also called p), l band, s band, c band, x band, ku band, k band, ka band, u band, v
band and w-band.
Among them, the band of the fire control radar is generally the range after the c-band, so the c-band, x-band, and ku-band are not just some small talk...
The higher the frequency, the shorter the wavelength.
The wavelength of hf can even reach hundreds of meters, while the w-band is only a few millimeters.
The L band is also the wavelength of the earliest radar, which means the first letter of "long" in English.
Later, engineers developed a radar with a wavelength of 10cm, which was defined as s-band.
s is the first letter of "short", which means short wave.
Later, radar with a wavelength of 3cm appeared.
This kind of radar is specially used for fire control targeting, so it is called X-band.
x is the "center" from the sight, and also represents a certain point on the coordinates.
The shorter the wavelength, the higher the resolution.
for example.
When people watch short movies, they often have a choice of resolutions, from 360p, 480p to 720p, 1080p and 4k.
Different network conditions and playback equipment have the ability to playback different definitions.
What about the fire control radar?
It is equivalent to a mobile phone with high Internet speed and high configuration.
It can play 4k quality video clearly. With this quality, you can clearly see many details in the picture - such as the shiny oil on the face of Thai pants.
But ordinary detection radar can only see 360p images.
In this situation.
It will be very difficult for you to see certain details clearly.
but......
With the emergence of the one-dimensional imaging method proposed by Xu Yun, some variables have occurred in the above situation:
This is equivalent to Xu Yun optimizing the built-in hardware of the mobile phone so that it can achieve 1080p picture quality when playing 480p pictures.
True.
Although there is still a gap between 1080p and 4k, many obvious details can still be seen clearly.
Then under the watchful eyes of Ye Duzheng and others.
The L-waves emitted by the weather Doppler radar penetrate the clouds instantly, and the strong penetration brought by the long waves makes them fly very far away in an instant.
Flying, flying.
Some of them encountered L waves...
The J-6 fighter piloted by Chen Pingsheng.
The wavelength of the L wave of 300mm and the wave frequency of 2ghz appear to be "harmless to humans and animals", and successfully passed the J-6's fire control monitoring radar.
And quickly transmitted the fighter's information back to Factory 221.
One minute later.
Didi didi——
As a prompt sounded.
On the operation screen in front of everyone, a set of information quietly appeared.
This information contained 17 cross-section points, and Baozheng quickly transcribed them and translated the data.
length:
14 meters.
high:
4 meters.
Maximum width:
9 meters.
Flight speed:
723.5 km/h.
It is clear.
It is not difficult to see from this parameter.
This is definitely a fighter jet or reconnaissance aircraft in flight.
See this situation.
Sun Junren quickly came to the screen again.
I only see this moment.
On the 20x20 screen in front of them, there was a small green dot flashing slowly.
The dot flashes once each time.
A large number of location information parameters will pop up, and you can get the specific values with a little calculation:
"The flight altitude is 7753.4 meters, the range is 28.6 degrees west to north, and the straight-line distance is 458.98 kilometers..."
"The flight altitude is 7456.9 meters, the range is 27.9 degrees west to north, and the straight-line distance is 421.10 kilometers..."
"The flight altitude is 7777.7 meters, the range is 28.3 degrees west to north, and the straight-line distance is 367.42 kilometers..."
Sun Jun's Tong Kong suddenly shrank.
A few seconds passed.
He turned to look at the liaison officer who was standing at the entrance of the tent, but who had actually been paying attention to the internal communication equipment of the tent.
Just as he met Sun Junren's eyes.
The liaison officer quickly shook his head.
What he meant was obvious - the detection radar on the J-6 did not retrieve the L-wave signal, otherwise the pilot would have definitely contacted him.
that's all.
As the radar values were broadcast, a clear fighter jet flight path appeared in front of everyone.
300 kilometers.....
200 kilometers.....
100 kilometers.....
50 kilometers......
Half an hour later.
A fighter jet flew slowly over Sun Junren and others without changing its course the entire time.
"...."
Wait until the plane disappears from sight.
Sun Junren, who had been silent the whole time, turned his head blankly and looked at Ye Duzheng beside him for a long time.
Immediately afterwards.
Both eyes burst out at the same time...
One light.
One way...
He was able to shoot down U2 without using any hands or feet...
Dawn!
