Chapter 598 Air Raid? Air Raid!

Sure enough, the group started chatting as they ran.

A group of people here are discussing how to generate nanosecond-level pulse signals to achieve accurate measurement of the target's height.

On the other side, they were discussing how to process the echo signal from the antenna, how to amplify, filter, or mix it...

Ugh, the same old trick again? Hmph, Dr. Lan Ying has used this on me countless times. Can't you guys come up with a different approach?

Jiang Xia inexplicably recalled his experience of eavesdropping in a disguised underground laboratory of the Academy of Sciences, and couldn't help but chuckle twice.

But the chuckle was immediately interrupted by a violent cough.

Don't get me wrong, this isn't some little ahoge trying to attract attention. Following the cough, you'll see it's actually a thin, frail researcher.

Unlike others, he not only wore a mask while running, but also ran a considerable distance away from the crowd, and the violent coughing sound came from him.

Hey buddy, wearing a mask while running when you have a cold? Are you trying to live too long?

And you guys, this guy is coughing so badly he can't breathe, and you don't even go to help him!

Jiang Xia looked at the researchers who had slowed their pace with dissatisfaction. In an instant, thoughts of passive-aggressive behavior, being excluded because she didn't fit in, and so on flooded her mind:

"Tsk! As expected, the more knowledge you have, the more indifferent you become! Your comrades are almost lying on the ground, aren't you going to help them?"

"Don't misuse your mask-making tips!"

After muttering to himself, Jiang Xia quickened his pace, shouting at the man as he walked, "Comrade! Take off your mask right now! You're having trouble breathing!"

Unfortunately, Jiang Xia, filled with righteous indignation, overlooked the grief in the researchers' eyes and their surprise at seeing him approach the man.

"Don't! Don't come here!"

The researcher, wearing a mask, saw Jiang Xia approaching and quickly reached out to stop her. She struggled to move her legs, which were squatting on the ground, to keep herself away from the crowd.

"What...what happened?!"

Jiang Xia was dumbfounded, and was pulled away by Xiao Mo who rushed over.

"he……"

"He has tuberculosis! The teacher won't let us near him!"

Oh, no wonder. Tuberculosis has claimed the lives of countless historical figures, both in China and abroad. For a long period, no one could do anything about it.

"Sickly ghost, sickly ghost," this slightly insulting term was originally used specifically to describe people who suffer from this disease.

Uh, right, even the famous Lin Daiyu was called a sickly devil by her brother Jia Baoyu, wasn't she?

Even in later generations, there were specialized tuberculosis hospitals conducting research on this stubborn disease.

It wasn't until the mid-80s, when the World Health Organization (WHO) and the International Union Against Tuberculosis and Lung Disease (IUATLD) promoted the establishment of standard chemotherapy regimens and adopted combination therapy, that the cure rate for tuberculosis was increased to over 90%.

In the past, tuberculosis was even called "the cancer of the poor," and it was common for this disease to turn entire families into impoverished households.

……

"Teacher? No way! You mean, the one who got tuberculosis is Teacher Zhongyi!" Jiang Xia's eyes widened. No wonder he left so early, so that's why.

"Yeah! The teacher is sick and won't let us get close to him, but we can't do without him when it comes to radar!"

"So while everyone was running laps, the teacher would listen in from a distance to understand the problem that needed to be solved, and then go back to study it on his own..."

Comrade Xiao Mo took two deep sniffles and burst into tears.

"This... this radar has gone up into the air! But once it's up there, we find that its ability to handle ground clutter is terrible! As soon as the Tu-4 flies even a little low, the radar screen is full of clutter, and it can't capture any enemy information at all!"

"The teacher is so worried. He's coughing like this but he still doesn't want to go to the hospital. Every time we try to persuade him, he says that getting this disease is fate, and since going to the hospital won't cure it anyway, it's better not to waste time. He also said that he wants to figure out a way to deal with the noise before he dies, otherwise he won't be able to die in peace!"

Jiang Xia nodded and turned to look at Secretary Liu, who was also grieving.

"Hey bro! Go ask the old military doctors at Peking Union Medical College Hospital if they have isoniazid, rifampin, ethambutol, or pyrazinamide."

Secretary Liu nodded, took out a notebook and asked Jiang Xia to write down these difficult-to-pronounce characters before going to find the phone number as Jiang Xia instructed.

"Hmm, you mean you've already test-flown that Tu-4 that was dismantled into eight pieces?"

While waiting for Secretary Liu's reply, Jiang Xia looked at the middle-aged man who was still squatting on the ground coughing, and her heart clenched.

"Yes! There are too many problems, not just with the radar, but even the machine itself has issues!"

Is there a problem?

That's amazing!

"Structural vibration? And the plane is also veering off course? And there's a tendency to yaw and roll after takeoff?"

Jiang Xia continued to watch the middle-aged man with concern, watching him struggle to take off his mask, take a couple of deep breaths, and then quickly put it back on, before continuing to cough.

"Hey! How did you know about these problems!"

Hmph, how would I know? Of course, it's what those rough men of later generations said when they were explaining it to the flowers of the motherland.

These guys were so afraid that the young talents would forget the sacrifices of their predecessors that they practically disassembled the prototype and explained it to them.

Therefore, Jiangxia not only knew about the problems with the aircraft, but also knew that the modified aircraft lacked a user-friendly human-machine interface and relied on manual plotting and voice communication to report air situation information.

"One more question, was the one you loaded onto the plane domestically developed or from the Russians?"

"The Alliance's Conus! It's just a copy we made. But we used a reed relay, so it's much smaller. The only problem is the noise issue is too annoying!"

Jiang Xia nodded again, "That makes sense. It seems that apart from the earlier timing and minor technical changes, it's not much different from the original KJ-1."

"Jiang, how did you know the plane would have so many problems?"

Well, aside from the explanations given by those rough men from later generations, Jiang Xia also used a scanner when he first saw that big guy, so he knew the details of that plane perfectly!

Just as Jiang Xia was trying to find an excuse to cover it up, she noticed a bright red bloodstain on the middle-aged man's mask.

It started as a small spot, but as he coughed, the red color slowly spread, eventually staining half of his mask!

Heart……

it hurts!

Just as Jiang Xia was about to rush to help the person up, Xiao Mo suddenly darted out from beside her.

"Master!" A long, mournful cry rang out, like the cry of a cuckoo.

Along with the shout, a low-frequency vibration sound, like an old engine running under overload, came from somewhere.

It then transitioned into an alternating "Awoo—Awoo—" sound, which sounded like both the roar of a wild beast and the mournful wail of a siren, and was extremely penetrating.

"Air raid siren!"

"Get to the air-raid shelter quickly!"

The middle-aged man, with a sudden burst of strength, stood up abruptly, pointed at Xiao Mo, and shouted, "Don't come any closer! Quickly take the comrades into the air-raid shelter!"

"Master!"

"Come on!"

Xiao Mo wiped away her tears, turned around and pulled Jiang Xia into a dark hole.

As Jiang Xia ran, he turned his head repeatedly, watching the middle-aged man kick several researchers who were trying to move the machines placed on the open ground, urging them to leave quickly.

The middle-aged man, meanwhile, was pulling on the cable ties on the equipment, struggling to drag them to another location all by himself.

Air raid?

How dare they!
