The God of Wealth starts with doing whatever you want

BJ.

Xu Yun originally planned to have a few days of carefree fun before going back, but unexpectedly received a call from Zhao Weiguo that afternoon.

"Comrade Xu Yun, there will be a groundbreaking ceremony for a new model demonstrator aircraft at Chengdu Aircraft Industry Group at 8:00 AM tomorrow."

Academician Chen and his team would like to invite you over for a visit, as a formal introduction as a 'special technical advisor.'

Xu Yun hesitated for a moment, then agreed.

He knew that this was not just a simple visit, but a gesture to announce to the entire aviation industry that such an excessively young yet unfathomable technical advisor had joined the company.

The next morning.

A military transport plane took off from Beijing West Suburbs Airport, carrying Xu Yun and three academicians to Chengdu.

Inside the cabin, Academician Chen Wenyuan was still discussing the engineering details of the "high-frequency micro-amplitude oscillation flap" with Xu Yun.

"Mr. Xu, our materials institute has already begun the first round of trial production of the material processing parameters you provided."

Academician Wang Zhenguo interjected, "However, there's a question: when do you add the rare earth elements you mentioned, before rolling or during the annealing process?"

Add it in two batches.

Xu Yun pulled up the process flow chart on the plate and explained: "The first time 70% of the total amount is added during smelting, the purpose is to distribute it evenly in the matrix."

The remaining 30% is added a second time, before the final annealing, using surface penetration technology, specifically for in-situ generation of the interface transition layer.

"Wonderful!"

Wang Zhenguo slapped his thigh excitedly and said, "This way, we can ensure overall performance while precisely controlling interface characteristics!"
How could I not have thought of that…

Academician Li Weimin, however, was more concerned about electronic systems, saying, "Mr. Xu, our chip institute has completed the front-end design of the neuromorphic chip you designed and is preparing for tape-out."

However, regarding the manufacturing process, are you sure the existing 7nm production line is truly compatible?

"Only three key steps need to be adjusted."

Xu Yun said, "The alignment accuracy during photolithography needs to be improved by 0.3 nanometers, the thickness control of the deposition process needs to be precise to the atomic level, and the cleaning process after etching needs to be changed to the special solution I specified."

All the specific parameters are here.

The three academicians sat around the tablet, taking notes as attentively as elementary school students in class.

The transport plane pilot glanced back from the cockpit and couldn't help but whisper to the co-pilot, "Goodness, those three are titans of our aviation industry, why are they being so polite to that young man?"

The co-pilot lowered his voice and said, "I heard he's an extraordinary person; even Zhao** personally received him."

As for their background... that's highly classified, so let's not ask.

Two hours later, the plane landed at a military airport in Chengdu.

Several black sedans had been waiting for a long time and drove directly into the heavily guarded Chengdu Aircraft Industry Group factory area.

Deep inside the factory area, outside a newly built giant factory building, hundreds of people have gathered.

There were technicians in overalls, senior military officers with general stars on their shoulders, and many more elderly experts with graying temples but piercing eyes.

When Xu Yun stepped out of the car accompanied by three academicians, all eyes turned to him.

Surprise, curiosity, scrutiny, doubt... a mix of emotions mingled in the air.

Academician Chen Wenyuan was the first to walk to the temporary stage and take the microphone.

"Comrades, before the ceremony begins, please allow me to introduce a special guest."

He stepped aside to gesture for Xu Yun to come forward, and said in a loud and solemn voice, "This is Comrade Xu Yun, who has been formally appointed by the Equipment Development Department as the 'Chief Technical Advisor' for our military's new generation stealth fighter project!"

A low murmur arose from the audience.

too young.

This was everyone's first reaction.

Xu Yun looked to be no more than twenty-seven or twenty-eight years old, and standing among a group of expert officers whose average age was over fifty, he appeared particularly out of place.

"I know what everyone is thinking."

Academician Chen Wenyuan continued, "Three days ago, when Academician Wang, Academician Li, and I first met Comrade Xu Yun at the Xishan Guesthouse, we had the same thoughts."

but……"

He paused, his gaze sweeping across the room, and said loudly, "After eight hours of technical questioning, we three old guys have to admit that in many areas of aviation technology, Comrade Xu Yun has already taken the lead over us, and even over the world!"

Beside him, Academician Wang Zhenguo took the microphone, his tone even more excited.

"Comrade Xu Yun's proposed gradient nanocrystalline composite material scheme has increased the fatigue life of my country's aerospace materials by five times!"
His adaptive plasma stealth coating reduced the radar cross-section of fighter jets by two orders of magnitude!
There are also neuromorphic chips, eddy current active control technology... each one is a revolutionary breakthrough!

In his concluding remarks, Academician Li Weimin succinctly stated: "I can say with certainty that the addition of Comrade Xu Yun will shorten the development cycle of my country's new generation of fighter jets by at least three years and improve performance indicators by at least one generation."

This is a historic opportunity!

The endorsement from these three titans gradually quelled the doubts from the audience, replacing them with shock and curiosity.

Xu Yun walked to the microphone and, without much small talk, got straight to the point.

"Thank you for the kindness of the three academicians, and thank you for the trust of all my comrades."

I'm standing here today not to prove how great I am, but to tell everyone that we are about to usher in a completely new era.

He brought up his tablet and projected the image onto the large screen behind the podium.

That was a holographic 3D model of a new generation of fighter jets, with smooth lines, a unique aerodynamic layout, and those exquisitely crafted internal structures.

"This is not a fantasy, but a blueprint that has been fully verified theoretically and is about to become a reality."

Xu Yun's voice was calm yet powerful: "Within three months, the first batch of test parts will roll off the production line; within six months, the verification machine will be fully assembled; and within a year, we will see it take to the skies!"

There was thunderous applause.

This time, there was no more doubt, only shock and anticipation.

The groundbreaking ceremony was simple, with no ribbon-cutting, no firecrackers, only the roar of dozens of precision machine tools starting up simultaneously at the chief engineer's command.

The sound was like the breathing of a giant beast awakening.

After the ceremony, a leader walked up to Xu Yun and said with a kind smile, "Chief Engineer Xu, I am Liu Zhenguo from the Air Force Equipment Department."

I heard that you not only understand design, but also have unique insights into overall systems?

"Perfect timing! We have a few other projects underway, and I was wondering if you'd be interested in... offering some guidance?"

The words were spoken politely, but Xu Yun understood the underlying meaning.

This is to see just how "good" he really is.

The three academicians exchanged glances, and Chen Wenyuan laughed, "Old Liu, are you testing our Chief Engineer Xu?"

"How dare I! How dare I!"

Chief Liu waved his hand repeatedly, but the expectation in his eyes could not be hidden as he said, "It's just a few self-developed new equipment pieces. I'd like Chief Engineer Xu to help me check them out and see if there are any details we've overlooked."

Xu Yun smiled slightly and said, "Commander Liu, you're too kind. It's my honor to learn from you and visit."

Therefore, the original return trip was temporarily adjusted.

Accompanied by Chief Liu and three academicians, Xu Yun began a "visit and guidance" tour of several classified projects of Chengdu Aircraft Industry Group.

The first stop was the drone research and development center.

Inside the huge workshop, three uniquely shaped drones are being assembled.

With a wingspan of over twenty meters, it adopts a rare joined-wing configuration and the fuselage surface is covered with a special matte coating.

"This is an improved version of the 'Dark Sword', a high-altitude, long-endurance stealth drone."

The project leader, a middle-aged expert in his forties, proudly introduced the project: "It has a maximum service ceiling of 25,000 meters, an endurance of 48 hours, and a full-band stealth design, enabling it to perform reconnaissance, surveillance, and even ground attack missions."

Xu Yun walked around the drone, his gaze lingering for a moment on the connection between the wing and the fuselage.

"Is the composite material skin joined to the titanium alloy frame using traditional bolt connections?"

The person in charge was taken aback: "Yes, is there a problem?"

"It's not a big problem, but it can be optimized."

Xu Yun squatted down and pointed to the connection, explaining: "Bolt connections can cause stress concentration. In high-altitude and low-temperature environments, the difference in the thermal expansion coefficients of different materials can lead to fretting wear, and long-term use may cause fatigue cracks."

He pulled up his tablet and quickly drew a simple diagram.

"It is recommended to use a 'gradient transition connection'—adding three transition layers between the composite material and the titanium alloy:"

The first layer is a woven layer of composite materials and metals, the second layer is a flexible adhesive layer, and the third layer is a shape memory alloy compensation layer.

This ensures connection strength while eliminating thermal stress, increasing lifespan by at least three times.

The workshop was completely silent.

Several young technicians gaped, while the person in charge quickly took notes, then suddenly looked up and asked, "Chief Engineer Xu, what are the specific material proportions and process parameters for this transition layer...?"

"I'll send it to you later."

Xu Yun stood up and pointed to the drone's air intake with a smile.

"And here, although the S-shaped air intake can shield the engine blades, the bending angle is too large, which will cause airflow separation and affect engine efficiency."

It is recommended to adjust the second bend from 35 degrees to 28 degrees, and to add a miniature vortex generator array to the inner wall.

He brought up a complex airflow simulation on the tablet, where the red and blue streamlines clearly showed the difference before and after optimization.

"With this modification, the total pressure recovery coefficient can be increased by 4.2%, and the engine thrust can be increased by about 3%."

The person in charge was completely convinced.

He shook Xu Yun's hand repeatedly, saying, "Chief Engineer Xu, you have such a sharp eye! We've been debating these two issues for half a year without reaching a conclusion, and you saw through them at a glance!"

Chief Liu and the three academicians looked at each other and smiled, their eyes full of smugness that said, "I told you so long ago."

The second stop was the aircraft engine test stand.

Through the thick observation window, a massive turbofan engine was running at full speed, its blasts of heat distorting the air.

"This is an improved version of the 'Taihang', with a thrust of 14.5 tons and a thrust-to-weight ratio of 8.2, which has reached the international advanced level."

The chief engineer of the engine was an elderly man with gray hair.

He spoke with a heavy Northeastern accent, saying, "But during our tests, we found that the high-pressure turbine blades would experience high-frequency vibrations under extreme conditions. We revised the vibration reduction design three times, but the results were not ideal."

Xu Yun stared at the rapidly spinning turbine, his mind already automatically analyzing the system.

[Target of Inspection: High-Pressure Turbine Assembly for Aircraft Engines]

[Problem Diagnosis: The first-order bending mode of the blade is coupled with the excitation frequency of the combustion gas, causing resonance]

[Solution: Adjust the internal cooling airflow channel layout of the blades, change the structural stiffness distribution, and shift the natural frequency by 12%]

"Is the cooling channel for the blades a traditional serpentine circuit?"

Xu Yun asked.

"Yes, from the leaf root to the leaf tip, the S-shaped direction ensures uniform cooling."

The chief designer answered.

"That's where the problem lies."

Xu Yun brought up a three-dimensional cross-sectional view of the blade on the flat plate.

"The stiffness distribution of the serpentine loop is uniform, which causes the natural frequencies of different parts of the blade to be too close."

It is recommended to change to a 'variable stiffness design', with denser cooling channels at the blade root to increase stiffness;
The middle section of the leaf was modified into a wavy channel to reduce stiffness; the leaf tip was further reinforced.

He quickly drew out a new channel layout that looked like a string of carefully arranged pearls.

"At the same time, a set of miniature piezoelectric actuators is added at the blade root platform to monitor vibration in real time and apply reverse damping force."

With this two-pronged approach, the resonance problem should be solved.

The chief designer stared at the blueprints for a full minute, then suddenly slapped his thigh and exclaimed, "Brilliant! Variable stiffness design... How come I never thought of that!"

This not only solves vibration problems but also optimizes stress distribution and improves blade life!

He turned to his assistant and shouted, "Quick! Notify the design team to hold a meeting immediately! Remodel according to Chief Engineer Xu's plan!"

The third stop was the airborne weapons laboratory.

A dazzling array of missiles, bombs, and pods were displayed on the exhibition stand, ranging from traditional air-to-air missiles to the most advanced stealth cruise missiles.

"This is our latest achievement, the 'PL-21' ultra-long-range air-to-air missile."

A young expert wearing glasses explained, "It has a range of over 300 kilometers, uses a dual-pulse solid rocket motor, and features active radar + infrared composite guidance. It is capable of 'fire-and-forget' and multi-target attack." Xu Yun picked up a scale model of the missile and carefully examined the miniature wing surfaces on its body.

"Grate rudder?"

"Yes, the new generation of missiles all use grid rudders, which have high aerodynamic efficiency and fast response speed."

The young expert said confidently.

“The grille rudder does have advantages, but you’ve overlooked one problem.”

Xu Yun pointed to the edge of the control surface and said, "At high Mach numbers, the gaps in the grid will generate shock wave oscillations, which will not only increase drag but also cause the missile to baffle, affecting guidance accuracy."

He brought up the aerodynamics simulation software, entered a few parameters, and the screen immediately displayed the complex wave system formed by the repeated reflection of shock waves between the grids.

"It is recommended to add a 'micro vortex generator' inside the grille—a 0.2 mm high micro-turbulence plate at the entrance of each slit."

This allows for the formation of stable vortices within the gap, suppressing shock wave oscillations, reducing drag by 7%, and improving control precision by 15%.

The young expert was stunned.

After a long pause, he murmured, "Micro-eddy current generator... How come we didn't think of such a simple idea..."

"And a guidance head."

Xu Yun put down the model and continued, "Is the beam scanning mode of the active radar mechanical or electronic?"

"Electronic phased array antenna."

"So, have you compensated for the mutual coupling effect between the antenna elements?"

"...it compensated for the basic part, but..."

"not enough."

Xu Yun shook his head and brought up a complex electromagnetic field calculation interface.

"When a phased array antenna is scanning, the mutual coupling between elements will change with the scanning angle, resulting in beam distortion and sidelobe elevation."

A full-band, full-angle mutual coupling database needs to be established, and real-time compensation needs to be performed in signal processing.

I can provide this algorithm, which can increase the detection range by about 8% and improve the anti-interference capability by one level.

The young expert was speechless and could only frantically take notes.

Fourth stop, fifth stop, sixth stop...

From avionics systems to flight control software, from stealth coatings to ejection seats, Xu Yun could pinpoint problems precisely wherever he went and propose ingenious improvement solutions.

He didn't just talk in generalities; he went into the specifics of material proportions, structural parameters, and algorithm logic.

Some of the suggestions even overturned traditional design concepts, enlightening even veteran experts who had been studying for decades.

The group following Xu Yun on the tour grew larger and larger, from the initial dozen or so people to the later dozens, and finally almost all the technical backbone of the entire factory came after hearing the news, crowding every workshop and every laboratory.

They looked at the young man, their eyes shifting from initial doubt to surprise, then to admiration, and finally to utter worship.

"This isn't just a tour guide...this is a technological revolution!"

An elderly expert with white hair exclaimed, "I've worked in aviation for forty years, and I've never seen such a comprehensive, insightful, and knowledgeable expert!"
How old is he? Twenty-eight? Twenty-nine?

"I heard he's self-taught."

Someone nearby whispered.

"Self-taught? If this is self-taught, then all of us with formal training can retire!"

The visit lasted a full six hours.

When Xu Yun walked out of the last laboratory, it was already getting dark.

General Liu personally handed over a bottle of water and exclaimed, "Chief Engineer Xu, I've truly had my eyes opened today."

It's no exaggeration to say that the suggestions you made this afternoon are worth more than our entire year's research and development investment!

The three academicians nodded in agreement.

Chen Wenyuan laughed and said, "Old Liu, do you believe me now? Our Chief Engineer Xu is a real treasure."

"I believe it now, I completely believe it!"

Commander Liu shook Xu Yun's hand and said sincerely, "Chief Engineer Xu, please don't hesitate to ask if you need anything in the future! The Air Force will definitely give you its full support!"

Xu Yun took a sip of water to moisten his slightly dry throat.

He looked around at the experts and technicians who were still having a heated discussion, and at the equipment in the workshop that represented the country's highest level of industrial development. Suddenly, an idea came to mind.

An idea he had been thinking about for a long time, but never had the chance to realize.

"Commander Liu, I have a favor to ask."

Xu Yun put down the water bottle, her tone serious.

"Tell me! As long as I can do it, I won't hesitate!"

Commander Liu patted his chest confidently.

Xu Yun's eyes lit up as he looked at the faint outline of fighter jets visible in the hangar in the distance.

"I want to... pilot a fighter jet myself."

The air suddenly became quiet.

Chief Liu was stunned, as were the three academicians, and all the experts and technicians who hadn't yet dispersed were also stunned.

Piloting a fighter jet?
A technical expert with no flight training is going to fly a fighter jet?
"Chief Engineer Xu, this..."

Commander Liu looked troubled and said, "Fighter piloting is no joke. It requires long-term professional training. Overload training alone takes several months, not to mention the operation of complex avionics systems, air situational awareness, and emergency response..."

"I know."

Xu Yun nodded, still smiling firmly, and said, "But I have studied the flight manual and simulated the operating procedures."

Moreover, I can start with a two-seater aircraft, piloted by an experienced pilot.

He paused, then added, "I just want to experience firsthand what it feels like to actually fly the technologies I designed."

This has irreplaceable value for subsequent improvements and optimizations.

That makes perfect sense.

It is indeed a pity for an aircraft designer to never have personally flown the aircraft he designed.

Commander Liu hesitated.

He looked at the three academicians, and Chen Wenyuan pondered for a moment before saying, "Old Liu, Chief Engineer Xu's safety must be guaranteed."

However, if it's just a trial flight, there shouldn't be any major problems under the instructor's constant monitoring.

and……"

He lowered his voice and said, "Chief Engineer Xu's contributions to our aviation industry deserve this treatment."

Wang Zhenguo and Li Weimin also nodded in support.

After thinking for a long time, Chief Liu finally gritted his teeth.

"Okay! I'll arrange it! But there are a few conditions."

First, we must fly two-seat trainer aircraft;
Second, the instructors must be top-notch ace pilots;

Third, the flight training is limited to basic operations and no aerobatic maneuvers are allowed;

Fourth, if the instructor deems it dangerous, the plane must return to base immediately.

"no problem!"

Xu Yun smiled, his smile filled with youthful excitement.

The news spread that evening, causing a sensation throughout the entire base.

"Have you heard? Chief Engineer Xu is going to fly a plane!"

"Really? Isn't he a tech guy?"

"A technical genius! He stunned all our experts this afternoon! Now he wants to experience flying firsthand, and Commander Liu has given him special permission!"

"Which one is it flying? J-10S? J-16?"

"It's definitely the J-10S two-seat trainer jet, which is relatively mild."

Who is the instructor?

"Who else could it be? Our base's ace, the Golden Helmet winner, Li Hao!"

"Captain Li? Good heavens, that's top-of-the-line!"

Meanwhile, at the base's flight simulation center.

Xu Yun was sitting in the J-10S full-motion simulator, receiving emergency training.

The flight instructor, Li Hao, is a capable man in his early thirties with over 3000 hours of flight time and a two-time winner of the "Golden Helmet" air combat competition.

He watched Xu Yun skillfully operate the dashboard, a hint of surprise flashing in his eyes.

"Chief Engineer Xu, have you worked with flight simulation before?"

"I've played with some civilian simulation software myself."

While adjusting the head-up display parameters, Xu Yun replied, "However, the operating logic of military aircraft is indeed much more complex."

"More than complicated..."

Li Hao pointed to the dense array of switches: "The fire control system alone has twelve modes, the radar has eight scanning methods, and the electronic countermeasures have six contingency plans."

Normally, pilots need two years of training before they can fly solo, but you only did it one night…

"I'll try my best to remember."

Xu Yun smiled, and the system in his mind began to operate.

[Flight operation skills loading...]

[Importing J-10S full system simulation data...]

[Emergency response plan generated...]

[Muscle memory enhancement begins...]

An invisible stream of knowledge flooded into Xu Yun's mind, and his fingers gently caressed the control lever and throttle lever, a strange sense of familiarity welling up within him.

It's as if... he has flown hundreds of times.

After two hours of emergency training, Li Hao's expression changed from doubt to shock.

"Chief Engineer Xu, are you sure this is your first time operating a real fighter jet?"

"This is my first time using a simulator."

Xu Yun's answer was perfectly flawless.

"But your operational proficiency... has already surpassed that of many junior pilots."

Li Hao shook his head and didn't ask any more questions: "See you at the airport at nine o'clock tomorrow morning. Remember to follow my instructions in the air and do not operate on your own."

"clear."

Xu Yun solemnly agreed.

Xu Yun slept exceptionally well that night.

He dreamed that he was piloting a fighter jet, soaring freely among the blue sky and white clouds, and that the technologies he had designed himself were performing perfectly in flight.

Reality is about to be even more amazing than dreams.

The next morning, at the Chengdu Aircraft Industry Group's test flight base.

The sun was shining brightly, and the sky was cloudless.

A J-10S two-seat trainer jet with a yellow-green paint scheme sat quietly on the runway, where ground crew were conducting final checks.

Wearing a custom-made anti-G suit and a flight helmet, Xu Yun walked toward the fighter jet accompanied by Li Hao.

The area was surrounded by people.

Three academicians arrived, Chief Liu arrived, the factory's experts and technicians arrived, and even many pilots rushed over upon hearing the news, all wanting to see how this young chief engineer would fly a fighter jet! (End of Chapter)
