Chapter 364 The Fighter Jet Heat Dissipation Problem, Huang Qingyao Wants to Compete

After confirming their identities, everyone went up to the top floor of the east wing, led by a hotel staff member.

Wang Rui, Zhang Yue, and Cai Wei, having returned from the Northwest, were more vigilant. They called the security personnel to bring out the detection equipment and scanned all the rooms. Only after confirming that there were no problems did they begin to choose their rooms.

After some discussion, everyone tacitly agreed to reserve the suite with the best view and two bedrooms for the two big spenders, Lin Dong and Xu Qingling.

After everyone was assigned to their rooms, they began packing their belongings, changing clothes, and getting ready to go out and have fun.

Lin Dong went into the room, changed into a swimsuit with shorts and a T-shirt that Xu Qingling had bought, and took out his confidential laptop.

Connect the portable external Beidou high-throughput satellite communication module, use Beidou secure communication to remotely access the secure satellite port of Chengdu Aircraft Industry Group's internal network, and then log in to Wang Xingguo's email.

Dingdong had just logged into my email when several new emails popped up, thanks to the 500Mbps communication module.

[Chengfei Cai Engineer]: Engineer Wang, please check the preliminary test data for the latest confirmed aerodynamic layout —

Lin Dong moved the mouse and clicked on the attached data table, a file of about 3 GB, and waited about 1 minute for it to download.

beep

The moment the attachment finished downloading, the network detected that it was not Chengdu Aircraft Industry Group's internal network, and a password box and 60 automatically popped up.

A file time lock for seconds.

Lin Dong calmly entered a password, the password box disappeared, and a large amount of data appeared. He quickly scanned it with the mouse.

Lin Dong thought for a moment, then asked Wang Xingguo about his standby status and quickly replied, "It's acceptable. This plan, along with the previous approved plan, will be used to create a model for in-depth wind tunnel testing."

There are also plans to be submitted to the technical department to determine the conductivity continuity of the canopy coating, as well as the serration treatment plan at the frame joints, and to have Engineer Wei do a full RCS calculation for the entire aircraft.

The J-20S features a rear cockpit, and the changes to the fuselage structure may create new radar scattering sources. The entire aircraft's RCS must be retested and calculated to ensure its multi-spectral stealth performance.

[Chengfei Engineer Huang]: Engineer Wang, this is the latest power supply and heat dissipation solution. We feel like we've reached the end of the road, but the test results still fall short of the J-20S's performance requirements by 28%.

"A 28% difference — power supply and heat dissipation are really damn bad."

Lin Dong saw the next email from Engineer Huang, shook his head, downloaded the attachment, entered the password, and viewed the specific design structure and test data.

Modern fighter jets have increasingly more avionics and greater power.

To complete the research and design of power supply and heat dissipation systems within the limited space and weight of a fighter jet is a challenge that has even exceeded [a certain level].

The design difficulty of the fuselage aerodynamic shape.

According to statistics from China's five major aircraft manufacturers.

In today's fighter jet development projects, the development costs of power supply and heat dissipation systems alone can consume 40% of the total development costs.

However, power supply is the foundation of operation, and heat dissipation is the foundation of combat; these are core issues that cannot be bypassed.

If the heat dissipation is inadequate, the avionics of the fighter jet will easily reduce power and frequency due to overheating. The most vivid example is the distributed pod design of the American Growler.

Originally, six aircraft could take on one J-16D fighter jet. If they could hold out for a while, they could figure out the frequency hopping pattern of the J-16D and then win by ganging up on it.

However, due to the enormous heat generated by gallium arsenide, coupled with the poor heat dissipation of the distributed design, the heat accumulation in the pod led to a reduction in power and frequency, which allowed the J-16D fighter jet to fight back and kill six of them.

"This data has reached the system's limit."

Lin Dong scanned the test data, pondered for a few seconds, and quickly replied: "Scrape down the current system design and start from scratch, abandoning the current distributed heat dissipation design."

By integrating the cooling systems of auxiliary power, emergency power, environmental control, flight, fire control, and engines into a central, unified integrated thermal management system, the system efficiency can be significantly improved and the system weight reduced.

We then contacted the electronics company to optimize the distribution and arrangement of the gallium nitride active phased array radar, increasing the heat dissipation area and reducing the heat dissipation burden.

If they don't understand, just give them these papers and say that I, Wang Xingguo, relayed them to them.

Finally, we contacted 624 and asked them to improve the exhaust pipe of the WS-15 engine.

Five months ago, they studied the WS-19 engine and, in order to further reduce its infrared signature, developed a technology that "injects cold air from the high-temperature exhaust gas flow in the tail nozzle for cooling".

"Let's improve the 624 and use it in the WS-15 engine to reduce the heat generation of the WS-15 engine, and also further reduce the engine's infrared signature."

Lin Dong quickly provided a complete set of improvement ideas, attached relevant papers, and pressed the send button.

After sending the email, Lin Dong finished dealing with two other minor issues in the emails. Just as he was about to log out of his email, shut down his computer, and end his workday, Huang Gong replied to his email.

[Chengfei Engineer Huang]: Engineer Wang, the unified central cooling solution involves a very complex system design and control model. Even slight flaws in the hardware and software design can easily lead to localized heat buildup, causing reduced equipment power and damage.

If you thoroughly understand the material covered in these two months, you'll be able to design a basic, practical central cooling solution.

First, develop the system solution. If there are overheating issues during testing, then gradually improve and optimize it. Don't say it can't be done before you've even started!

Lin Dong sent the email, ignored Huang Weibing's reaction, logged out of his email and remote connection, and checked the time.

"Thirteen minutes, today that guy Huang wasted a few extra seconds of time —"

Lin Dong muttered something to himself, unplugged the Beidou satellite communication module, shut down his laptop, and ended his work for the day.

Just then, the door clicked open.

Xu Qingling, wearing a one-piece swimsuit, opened Lin Dong's room door and walked in, holding her phone.

"Dongdong, are you done with your work?"

Seeing that Lin Dong had already closed his notebook, Xu Qingling asked, "Are Yao Yao and the others almost done changing their clothes?"

"Come here, let me take a look."

Lin Dong looked at Xu Qingling in her swimsuit and immediately smiled and waved.

"Does it look good? I bought it the other day when I went shopping with Yao Yao and the others."

Xu Qingling obediently walked over and turned around in front of Lin Dong.

Standing at 1.7 meters tall, she already possessed a graceful figure in her second year of high school. As her skirt fluttered, her hair, tied behind her back, also swayed.

"Great, it looks very good."

Lin Dong nodded firmly, put the notebook away, and suddenly grabbed Xu Qingling's hand, pulled her close, and kissed her.

"oops!"

Xu Qingling leaned against Lin Dong, gritted her teeth, and warned weakly, "If you attack me like that again, I'll bite you—"

"Then we won't launch a sneak attack."

Lin Dong smiled and leaned down to kiss Xu Qingling again on the lips.

Xu Qingling blushed and glared, but seeing Lin Dong's shameless appearance, she had no choice but to urge him, "Let's go out, or they'll have to wait."

talking.

Xu Qingling pulled Lin Dong outside, walking quickly, afraid that he would attack again.

"Qingling, Lin Dong, have you finished? I saw there's an infinity pool by the sea here—" Just as the two reached the suite door, Huang Qingyao knocked on the door.

"They're here!"

Xu Qingling quickly responded, opened the door and went out. Huang Qingyao, Li Tao and others were already waiting in the corridor.

"What were you doing in the room just now? Why were you taking so long?"

When Huang Qingyao saw Lin Dong and Xu Qingling come out, she glanced at them and immediately leaned over to gossip, asking, "And why is Qingling blushing?"

"Single dog, don't ask so many questions."

Lin Dong replied bluntly, glancing at the people in the corridor.

The girls seemed to have made a pact: Huang Qingyao, Xia Ran, Su Yue, and Jiang Caiping all wore one-piece dress-style swimsuits. Apart from the different fabric and slightly higher skirts, the overall style was not much different from their usual dresses.

Feng Mei, Luo Xiaomei, and Lu Qiong, the three adults, had a more open style, with sleeveless swimsuits, but the overall style was still conservative, unlike the two-piece narrow fabric swimsuits that could be seen on the beach outside the window.

As for Li Tao and the others' swimsuits, they were the same as Lin Dong's.

A pair of waterproof capri shorts paired with a waterproof T-shirt—simple and understated.

"They've left, they've gone down."

Seeing that everyone had arrived, Lin Dong took Xu Qingling's hand and walked towards the elevator, saying, "This hotel has a seaside infinity pool. We can go there for a swim and have some drinks."

If you want to go into the sea, bring a lifebuoy. Don't go in alone. Rui, you guys are coming back from the Northwest, so go out and call for security personnel.

"understood."

Wang Rui responded from the front: "We're not going out—we just arrived here, and the spies haven't even realized what's happening yet."

"Big spender, what are your plans for the next few days?"

Huang Qingyao leaned closer again and asked Lin Dong, "Are there any special perks?"

"What else can we do? Go swimming for a while, then have a barbecue on the beach in the evening."

Tomorrow, after you wake up, a yacht will arrive, and everyone can go out to sea for two nights. You can go deep-sea fishing, ride jet skis, go diving, and when you come back, you can go sailing, water skiing, and sunbathing. — If you want to go out for other activities, you can go together; I won't arrange that.

Lin Dong looked at Huang Qingyao and said, "It's a deal, if you get tanned after a few days of playing around, don't blame me."

"Hiss, a yacht heading out to sea?"

Huang Qingyao nodded excitedly, "For the sake of the yacht, I won't complain about getting a tan."

"Yes, but the yacht only has five double rooms and two single rooms. If there aren't enough rooms, you'll have to sleep on the sofa," Lin Dong nodded.

"I'll sleep on the sofa?"

Huang Qingyao immediately protested, "No way, that's not fair! Whoever loses the competition later sleeps on the sofa!"

"What kind of competition? Drinking?" Lin Dong glanced at the guy.

"I don't drink alcohol, and I'll be swimming, freestyle!"

Huang Qingyao explained her competition plan: "But we need to eliminate the physical differences between men and women, and based on the world record difference in performance between men and women, the men's scores should be calculated at 90%!"

"Yo!"

Lin Dong immediately smiled: "You've even checked the world swimming records, you seem very confident."

"Of course—"

Huang Qingyao was determined to avenge her previous humiliation of drinking in Lin Dong's hometown during summer vacation, and confidently declared, "I was a first-grader..."

I learned to swim, and I go swimming every summer.

But as soon as she finished speaking, Xu Qingling couldn't bear it and turned her head away, and Xia Ran also turned her head away, too ashamed to look at her.

"Xiao Dong, the rest of us don't need to sleep!"

At this moment, Wang Rui, Cai Wei, and Zhang Yue overheard the conversation, exchanged excited glances, and exclaimed, "We have sea fishing gear! The three of us can fish all night long!"

"Brother Rui, let's play for a bit."

Lin Dong looked at Huang Qingyao, who had a confident expression, and said with a smile, "You said it, if you lose, you sleep on the sofa."

"Anyone who goes back on their word will have to keep Wangcai company." Huang Qingyao didn't back down at all. "Wouldn't that mean you won't be punished?"

"roll!"
