Chapter 320 From a monthly salary of 10,000 to an annual salary of one million! Yunkun’s expansion

Bao Xiangwen was alone in the interview room.

The air-conditioning is sufficient and a bit chilly, and the lights above are exceptionally bright, yet exceptionally soft, without any dazzling feeling.

Large-screen monitors, Moss Ai second-generation speakers, projectors and other equipment are all available, and there is even a rich tea and fruit plate on the table.

A "crunch" sound!

The glass door was pushed open, and three interviewers walked straight in.

The young man in the lead was in his early twenties, tough and handsome, and wore a well-tailored suit, which made his figure look even stronger and taller.

On the left is an energetic middle-aged man with slightly concave cheeks and piercing eyes, wearing a loose casual coat.

Finally, there was a woman in her thirties, wearing a professional suit with meticulous matching of lining. It was obvious that she was an extremely rigorous person.

"Good morning, you three. I am Bao Xiangwen, the interviewer."

Bao Xiangwen took the initiative to stand up and introduced himself.

"Please sit down, you're welcome."

The other is a materials scientist with solid basic knowledge of materials science and engineering, including an understanding of material structure, performance, processing and characteristics;

Be familiar with the research and development methods of various composite materials and high-temperature resistant materials, and be able to design new materials to meet the requirements of spacecraft parts;

The last one is a rocket engineer who is familiar with various propellants, thrust control, and aerodynamics application fields.

After a long time, Bao Xiangwen read the entire material, raised his head and answered.

"60,000?! Don't lie to me. Stop talking. Weiwei is home and I have to cook."

Bao Xiangwen still showed no fear and narrated clearly and logically.

"Honey, the interview went well and I will start the job next Monday."

Under vacuum conditions, it can even reach 300 tons!

"Mr. Chen, this technology is one level more advanced than the engine design of Fengjing Research Institute.

Bao Xiangwen replied in a muffled voice that he had read job postings online. With his ability, it should be more than enough to apply for a supervisory engineer (P3) job, with a salary range between 26,000 and 32,000.

"Mr. Bao, what are your salary requirements?"

No, no, no! What I mean is that when considering whether to choose a garage or a subsidy, you don’t have to consider whether to join a job.

The wife hurriedly hung up the phone.

Since the establishment of Yunkun, this is the fourth "P5" level employee!

Chen Heyu waved his hand and said.

Bao Xiangwen was a rare arrogant person. He straightened his back, looked at the blue sky and white clouds in the distance, and said leisurely.

Third, flexibility: supplementary combustion technology allows the rocket engine to adjust the fuel ratio at different stages to adapt to different mission requirements;

Fourth, adaptability: both liquid oxygen and kerosene are common and easily available fuels, so the liquid oxygen and kerosene high-pressure supplementary combustion technology has strong adaptability and operability..."

"What? Is there such a thing?"

This is a duty that she must fulfill. Although some candidates were eloquent and eloquent during the interview, after investigation, they found that the other party had no real materials at all.

Let’s first talk about liquid oxygen kerosene high-pressure supplementary combustion, which is a core technology to improve the thrust and efficiency of rocket engines.

"But, it's really 60,000."

First, mixed cycle combustion technology is used to burn fuel and oxidant separately in different combustion chambers, and use the high pressure and high temperature generated by the exhaust gas to drive the turbine pump;

Secondly, the fully cooled cooler technology is improved to allow part of the fuel sent from the turbine pump to flow on the combustion chamber wall to cool the combustion chamber and nozzle, which can effectively reduce the temperature of the combustion chamber and thereby improve the durability and reliability of the engine.

sex;

Thirdly, the engine is designed with multi-point ignition function, so that even if ignition fails, it can still successfully carry out the mission or return safely;

Finally, strengthen the structural design, use high-strength, lightweight materials and advanced manufacturing processes to cope with the challenges of multiple launches and recovery."

Wei Guangji was the first to ask.

Chen Heyu asked casually.

With my ability, I really can’t see any problem. If I insist on it, the only problem is that the ballast capacity of the chamber is too high. With a value of 30 MPa, once the slightest foreign matter appears in the fuel, it will..."

"Thank you, sorry for the trouble."

Shi Yijia added.

After some communication, the three of them informed Shi Yijia of the interview results.

Chen Heyu picked up a pot of lemonade, poured himself a glass, took a sip, and waited patiently.

As expected of the founder of Future Technology and Shanhai Microelectronics, he is truly arrogant!

"Of course, I joined the institute in 2006 and obtained the researcher qualification in 2008. Since September 2010, I have been independently responsible for the design and development of cryogenic propulsion engines, solving problems in liquid oxygen kerosene high-pressure supplementary combustion and liquid oxygen methane engines.

, providing complete technical solutions.

From a monthly salary of 10,000 to an annual salary of one million! It only took a few days?!

Bao Xiangwen had an unreal feeling. He was dazed and asked subconsciously: "Mr. Shi, isn't the position I'm interviewing for a senior engineer in charge? Is it only a P3 level?"

Seeing the big boss nodding, Shi Yijia went straight to the topic.

In addition, according to your level, we can equip you with a three-bedroom house and a mobility scooter worth 500,000 yuan in Qindao. If you accept this benefit, the housing subsidy and transportation subsidy will be automatically canceled."

…

"Be bold and double it!"

Bao Xiangwen raised his voice, feeling a little happy and couldn't help but ask: "Can I know the name of this designer?"

Bao Xiangwen opened his mouth, hesitating and not knowing how to explain.

P5!

Pushing open the glass door of the living room, he stood on the balcony, breathing in the sea breeze, and quickly took out his mobile phone to report to his wife that she was safe.

After Wei Guangji graduated, he went abroad for further study and had been active in the European aviation industry for many years. He had little knowledge and did not understand the abusive behavior of some people.

"Of course it's no problem. After you think about it carefully, you can inform me at any time. You can also check in first during this period."

"Not bad! Take another look at this material?"

"Self-generated pressurization! Use a heat exchanger to heat methane and liquid oxygen so that the fuel in the tank pressurizes itself after continuous consumption, which can effectively avoid explosions caused by helium pressurization."

"Mr. Bao, after the evaluation of your boss, Mr. Wei, your entry level is P5. Your position is the chief engineer of the Rocket Propulsion Department. You have a probation period of two months and no discount on salary and benefits.

The wife asked curiously, and at the same time she felt pleased and proud of her husband.

"Okay, please wait a moment, I need a moment."

HR Director Shi Yijia raised a pointed question.

Two hours later, Bao Xiangwen lay on the soft sofa and looked around. The apartment covered an area of ​​120 square meters, with three bedrooms, one living room and two bathrooms, complete with furniture and appliances.

Shi Yijia understood instantly, glanced at the interview form, and the eye-catching "P5" words came into view, and her heart suddenly trembled.

Chen Heyu nodded with satisfaction and handed over a document again. This was a new engine that he had re-improved based on the Raptor engine.

Bao Xiangwen talked eloquently. When he talked about his areas of expertise, his eyes were bright and full of confidence, and his original futile energy was completely gone.

Bao Xiangwen paused for a moment and continued to add.

At the same time, aviation research institutes across the country are experiencing a wave of resignations.

Bao Xiangwen was stunned for a moment. He knew that Yun Kun's treatment was good, but he didn't expect that it would be far beyond his imagination.

“Genius design!”

"Just look at the company's arrangements."

Bao Xiangwen said frankly.

"I am extremely optimistic about Mr. Bao's abilities. If he were placed at the European Space Agency, he would be able to get a senior manager position."

With the "ding ding ding" sound in his mind, he thought for a moment and wrote "P5" directly in the interview evaluation area.

Shi Yijia said in one breath, looking at the other person with a smile.

"Sorry, I would like to ask. From your explanation, it can be seen that you have rich experience in rocket engines and fuel ratios, but why can't any of your papers be found in mainstream domestic journals?"

He had no idea that the prototype of the technical document in his hand was SpaceM's Raptor engine.

Chen Heyu raised his finger and tapped on the table.

Monthly salary is 60,000 Chinese dollars, minimum salary is 15!

With a monthly subsidy of 5,000 yuan, the annual salary directly exceeds one million!

Bao Xiangwen thanked him.

Wei Guangji told the truth without any worries.

“If you don’t consider the factors of cost and manufacturing difficulty, I have three suggestions:

First, optimize the structural design of the combustion chamber: use pre-cooled liquid oxygen-methane propellant to surround the combustion chamber wall so that it can withstand high-temperature and high-pressure combustion gases;

"I am Wei Guangji, the general manager of Yunkun Space Company, this is the big boss Chen Heyu, and the other is Shi Yijia, the director of the human resources department.

"That's right, the boss has personally transferred your rank to you! Or if you have any other additional requirements, you can give me feedback.

A suspicion arose in Shi Yijia's heart, but as a wage earner, she naturally wouldn't ask any more questions.

It usually consists of a combustion chamber and a nozzle.

Bao Xiangwen replied dryly, speaking cryptically, with a look of helplessness on his face.

Wei Guangji was greatly shocked and couldn't believe it. He turned to look at Chen Heyu, as if he wanted to ask for confirmation.

"If you don't want to do it, get out of here! If you don't do it, others will do it!"

Bao Xiangwen couldn't stop grinning.

We all have a basic understanding of Mr. Bao’s situation. You were originally a technician at Fengjing Aviation Research Institute, mainly responsible for the rocket power system. Can you talk about your previous work?"

Bao Xiangwen was overjoyed. He was always happy to be recognized. Could it be that the P3 position he was interviewing for could be promoted to another level?

"There are many ways that can be achieved in theory. If you want to reproduce it perfectly, you still need constant experiments. Let me talk about my personal views first:

The specific operation method refers to injecting liquid oxygen and kerosene into the rocket engine combustion chamber at the same time. Under high-pressure and high-temperature conditions, more combustion products will be produced, further increasing the instantaneous injection speed and thrust.

Wei Guangji looked at Chen Heyu with a strange expression. This boss of his was really an all-rounder.

Each one is a top expert in the industry!

"Is Bao Xiangwen qualified?"

Chen Heyu nodded slightly. He had read so many professional books, and it was not for nothing. Even without the system's beep, he could tell that the other party's abilities and talents were definitely impressive.

Then through the coolant circulation in the pipes, the heat will be effectively taken away and dissipated to the outside;

Chen Heyu smiled, ignored Wei Guangji, took out a stack of documents from his hand, and handed them to Bao Xiangwen.

"I don't have enough connections. Even if I produce scientific research results, I don't have the right to authorize them."

Moreover, this technology has four advantages:

First, increase the thrust: supplementary combustion technology can increase the fuel mass flow and increase the energy release of the combustion reaction, thus increasing the thrust of the rocket engine;

Second, improve efficiency: supplementary combustion technology effectively utilizes additional fuel and improves the energy conversion efficiency of the combustion process, thus improving the combustion efficiency of the rocket engine;

Bao Xiangwen was secretly impressed.

"Mr. Bao, I understand. This is an engine design plan. Can you see if there are any problems?"

Bao Xiangwen said helplessly that this joy was destined to be kept in his heart and his wife slowly accepted it.

"Mr. Bao, what's the secret?"

Bao Xiangwen thought for tens of seconds, sorted out the logical order, and interpreted the words one by one.

"Later, I will ask my administrative colleagues to take you over to check in, and you will officially join the company next Monday."

"As for the liquid oxygen methane engine, it is a rocket engine that uses liquid oxygen (LOX) and methane (CH4) as fuel.

Look, I have all my suitcases with me?"

If put into use, "Dijiang" will become the second-largest active liquid rocket engine in the world, second only to the Tianding Rocket's RD-171 (7904 kN).

Among the first three people, one is a master in the field of spacecraft design, proficient in aerodynamics, structural design and human-computer interface interaction;

Chen Heyu?

Bao Xiangwen was secretly alarmed. He had heard someone say that the initial investment in the Yunkun project was 10 billion Chinese dollars, and there would be 20 billion Chinese dollars in additional funds in the future.

"Boss, Moss AI glasses 2.0 will be officially released tomorrow at 10 a.m., 1 million pieces in stock!"

No matter how you calculate it, it is several times more powerful than the original 10,000 yuan!

"Mr. Wei, how do you feel?"

"Boom!"

"I……"

Through a fine pipe network, some unburned fuel and oxidant are guided to flow along the combustion chamber wall, absorbing the heat generated by combustion and cooling it to an acceptable temperature;

Second, efficient heat dissipation: Use a full cooler to form a thin liquid film on the combustion chamber wall to isolate unburned fuel and oxidizer from the high-temperature gas generated by combustion, avoid direct contact, and reduce heat conduction.

Chen Heyu and Wei Guangji stood up to leave, leaving Shi Yijia alone in the room.

"Will it explode? Indeed! Aluminum alloy and Kevlar materials cannot withstand it at all. So what solutions do you have?"

Big boss?

"Please!"

Bao Xiangwen pointed to the black suitcase in the corner and couldn't help laughing.

Shi Yijia explained.

Bao Xiangwen opened the document. The first A4 paper printed a structural diagram of the engine, including the combustion chamber, fuel system, oxidizer system, guidance system and cooling system, as well as turbo pump, nozzle, valves and sensors.

Shi Yijia stretched out her hand, shook Bao Xiangwen's hand, and reminded her warmly.

"I want to increase the number of rocket launches and reduce launch costs. From your professional perspective, do you have any better suggestions?"

Chen Heyu asked with a smile.

By the way, you have a wife and children, right? Medical insurance can cover your immediate family members!”

He named it "Emperor River"!

The estimated parameters are sea level thrust of 400 tons (3921kN), vacuum thrust of 452 tons (4430kN), and combustion chamber pressure as high as 32MPa.

Basic monthly salary: 60,000 Chinese dollars, quarterly bonus every three months, year-end bonus at the end of the year, minimum salary of 15;

In other aspects, there is a monthly accommodation subsidy of 2,000 yuan, a transportation subsidy of 1,500 yuan, a food subsidy of 1,500 yuan, corporate pension, and supplementary medical insurance. We will also help you purchase them all.

"So happy? Do you have a salary of 30,000?"

It was several times more luxurious than his house in Fengjing.

In terms of fuel selection, it is methane (CH4) he just mentioned. Although methane has a higher combustion temperature and lower energy density than kerosene, its advantage is that it can be combined with liquid oxygen (LOX) to produce 200 to

A terrifying propulsion force between 250 tons.

As far as I know, the American space company SpaceM uses a fuel formula that uses methane (CH4) and liquid oxygen (LOX) as fuel to drive the Raptor engine."

In the combustion chamber, liquid oxygen and methane are mixed and ignited to produce high-temperature and high-pressure combustion gases, which are then injected through the nozzle to generate thrust.

Chen Heyu became interested, put aside Wei Guangji, and asked with a smile.

The director of the institute curled his lips and looked completely indifferent. He had no idea what impact the resignation of these people would have.

…

Third, use high-temperature-resistant alloys and high-pressure-resistant materials to construct key components such as combustion chamber walls and turbine pumps to increase their ability to withstand high-temperature and high-pressure environments;"

"Give me a moment, can I think about it first?

Zhang Nan called to synchronize the latest news from the company.

"Well, I understand. Remember to do what I told you last time!"

Chen Heyu ordered.

Gentlemen, there will be no updates at 0 o'clock these two days. I'm afraid it will affect everyone's rest. Gentlemen, please go to bed early.
