Great Power Technology

On March 19, 20xx, the GE-9X replica engine, codenamed "Qilian", had a 48-hour countdown to ground testing.

Yes, this engine, which took 7 months to build, finally has its own name before it is about to enter the final test.

Like other domestic aero-engine series, it is also named after domestic mountains. However, when initially choosing a name, whether to choose "Qilian" or "Hengduan" actually caused some controversy.

Ye Zhou advocated choosing Hengduan. After all, in the novel, Hengduan was always possible, which sounded domineering. However, his suggestion was unanimously rejected by the decision-making team of the sedan project team because it was considered unlucky.

Qilian Qilian literally means continuous, and in its original meaning it also represents the sky. It is a perfect name for the country’s first large bypass ratio and high thrust turbofan engine, while Hengduan , it always gives people a feeling of powerlessness.

For the first time, Ye Zhou felt that these usually extremely rigorous scientific researchers occasionally had a superstitious side, but he also felt that this statement had some truth, so he readily accepted it.

This morning, he got up a little later than usual. After washing, he prepared to go to the factory to work. But as soon as he walked out, he found that Chen Hao was already waiting at his door.

"Are you up? Why did you sleep for an extra half hour because you were too lazy today? As a result, I have to wait for you here for an extra half hour."

Ye Zhou looked at Chen Hao doubtfully, and while locking the door with his backhand, he replied:

"The preparation work has basically been completed. The engine has been hoisted on the test bench. There are not many things to do, so I just slept a little longer. What's the matter, do you have anything to do with me?"

Chen Hao nodded and motioned for Ye Zhou to follow him, pointed at a Hongqi H9 parked outside the door and said:

"It's also because you shouldn't be so busy in the past two days. I won't be busy with work today. I'll take you to visit someone."

"Visiting? Who? Is it important?"

Hearing Ye Zhou's question, Chen Hao paused for a moment and then replied:

"A very important person. His name is Tian Tian. He has made lifelong contributions to the field of aviation development. He participated in the design of our Turbofan 10 and Turbofan 15. By the way, he is Tian Zhenguo's son. Do you know Tian Zhenguo?"

Ye Zhou was stunned and said nothing.

Of course he knows, he knows too well.

The figure of trekking through the snowfield will probably never be erased from his heart for the rest of his life.

Seeing Ye Zhou's expression, Chen Hao thought he had never heard of this name, so he continued:

"Tian Zhenguo was an expert in the aviation field in our country in the last century. He was mainly engaged in materials. His technical concepts were very advanced at that time, and he had always advocated using turbofans to replace turbojets. However, at that time, turbofan technology was not suitable for us. It was so difficult that his suggestions were never adopted.”

"Later there was a large meeting where we were going to finalize the direction of the turbojet. He was sent to study in the countryside at that time. In order to catch up with the meeting, he insisted on braving the snow to catch the train despite the cold weather, and ended up freezing to death. On the way."

"After he died, his son took advantage of the resumption of the college entrance examination to enter college, and then entered the aviation field like him. The rest of the information can be found online, so I won't go into details."

"In short, Tian Ye is responsible for many of our key aviation development projects, but due to confidentiality requirements, his reputation is not very good."

"Four or five years ago, he was diagnosed with lung cancer. It has been delayed until now, and he is already very weak. After asking for instructions from his superiors a few days ago, we informed him of the details about the sedan chair project, and he strongly requested to meet him. The main person in charge of the bridal sedan project, so the higher ups appointed me and you - of course, the main thing is to meet you."

"After meeting the old man later, try not to over-stimulate his emotions and keep him emotionally stable as much as possible until the Qilian engine test is completed."

Ye Zhou nodded but still didn't speak.

This was not because he had nothing to say, but on the contrary, it was because he had too much to say, but it was all stuck in his chest and he could not say it out.

After getting in the car, Ye Zhou silently looked at the passing scenery outside the window, but the scene of the snowfield flashed in his mind.

It was a vast expanse of land, the sky and the earth were all white, with neither human beings nor hope in sight.

However, the old man still embarked on the path forward without hesitation, just to fight for that slim hope.

And when his son chose to inherit his father's legacy, what did he face instead of a snowfield?

Now, this snowfield is gradually melting away, and when the high temperature of 1900 degrees Celsius bursts out from the Qilian engine combustion chamber, even the last trace of snow will be evaporated, and what will be revealed in front of you will be extremely flat, It is an extremely wide road, but this old man named Tian Ye can only take one last look at this road.

The car parked inside a secluded nursing home. Chen Hao took Ye Zhou out of the car and walked into a small building set up alone by the lake. The security guard at the door saluted the two and then led them inside. the bedroom.

There, Ye Zhou finally met this man who devoted himself to China Aviation Development.

He was already very old, with the white hair on his head sparsely covering his scalp. His face had wrinkles like ravines, his lips were dry, and his cheeks were sunken, but his eyes still exuded a look as hot as the scorching sun.

Seeing the two people walking into the room, a middle-aged man standing by his bed quickly stood up and introduced:

"Dad, this is the person you said you wanted to meet before. This is Chen Hao, Secretary Chen. Is this Ye Zhou? Chief Engineer Ye, he is also the commander-in-chief of the sedan chair project and the executive secretary of the leadership team."

After hearing his son's introduction, Tian Ye forced himself to sit up and took a few breaths before speaking:

"I heard before that the commander-in-chief of this project is very young. I didn't expect that when I met today, it was beyond my expectation. Xiaoye, are you 30 this year?"

Tian Ye's tone of voice was still calm, but his breath was obviously a little disordered. Upon seeing this, Ye Zhou quickly stepped forward and sat in front of the hospital bed, held his outstretched hand and replied:

"Old man, I am 23 this year - I will be 24 in March."

"24,24 I was already 34 when I was admitted to college. The waves behind the Yangtze River push the waves ahead. Okay! Okay! Okay!"

Tian Ye said three good words in a row, and held Ye Zhou's hand harder and harder, but his body was so weak that Ye Zhou couldn't even feel a trace of pain.

This feeling made him even more sad.

He gently patted the back of Tian Tian’s withered hand and said softly:

"Old man, don't be anxious. Let's talk slowly. We have plenty of time. I will chat with you here today."

"That's not okay! Your project team has so many things to do, how can you waste time with an old man like me! I asked you to come here today simply because I wanted to meet you, just to fulfill a wish."

"Now that we have seen him, you should go back early."

Ye Zhou smiled and replied:

"Old man, it's okay. You don't know it yet, but our sedan project is almost finished. The engine prototype has been completely assembled. In two days, it will be put on the test bed for trial operation."

"So fast??"

The old man's originally wide eyes widened again. He looked at Ye Zhou in disbelief. After coughing a few times, he continued to ask:

"How can it be so fast? I heard from comrades that your project has only been in progress for more than half a year. How come the prototype is already out?"

Ye Zhou nodded and replied:

"It has been seven months since I started working on it. Many things are ready-made, so the progress is fast."

Hearing this, the old man sighed slightly, and then said:

"It's ready. Is there any technological breakthrough?"

"Yes, mainly because the thrust has been greatly improved. On the other hand, there are also innovations in heat-resistant materials and insulation materials."

"Please tell me in detail!"

At this time, the old man completely forgot that he was telling Ye Zhou to go back early a minute ago. After moving his body to find a relatively comfortable sitting position, he looked at Ye Zhou expectantly.

Ye Zhou pondered for a moment, starting with ceramic-based fluorescent iron reinforced materials, and then explained to him step by step the star rock TBC, the matrix, and the blade drilling model. The old man nodded repeatedly and waited for Ye Zhou to stop. He opened his mouth and said:

"There are a lot of new technologies. It seems that I am really old. I have thought about these technologies before, but I just can't come up with them. It depends on you young people."

"With so many new technologies, the thrust must be improved a lot, right? I heard that you are developing a commercial product with a large bypass ratio. The thrust should be able to reach more than 30 tons?"

Ye Zhou smiled slightly and replied:

"Old man, that's conservative. Our target thrust for this project is 70 tons, and the challenge thrust is 100 tons."

“70 tons?!?”

The old man coughed involuntarily, and Chen Hao on the side quickly handed him some water. After he took a sip to moisten his throat, he continued to ask:

"Xiaoye, don't lie to me, just say how much it is! How can it reach 70 tons??"

Ye Zhou did not directly respond to his doubts, but said:

"Old man, I'll leave you in suspense first as to whether it can reach 70 tons. We will have an on-site test drive in three days, and we will be able to see the basic data by then."

"In addition, after the ground test, we will also do a high-altitude test. The data at that time will be the most accurate data. Then you will see if there is 70 tons."

The old man stared closely at Ye Zhou's eyes, as if he found that there was no trace of joking in his eyes. Finally, he sighed and said with some emotion:

"Seventy tons. I have been engaged in aviation development all my life, and I have never thought of this number. I thought I would be able to feel at ease after meeting you today. But based on what you said, I'm afraid I will have to endure a few more months."

"That's not a matter of several months, old man. After the high-altitude test run, we still have to get on the plane. After the plane is finished, we still have to mass-produce it. After the mass-production, we still have to equip it. Don't you have to wait for another seven or eight years? "

Tian Ye shook his head, with a somewhat gratified smile on his face, and then said half seriously and half jokingly:

"If I really live for seven or eight years, then I will be able to see most of the Nantianmen Project you mentioned? If I am not wrong, this project has nothing to do with you, right?"

Ye Zhou smiled and did not answer, but the old man had seen through everything from his expression.

After talking too much in a short period of time, the old man was a little out of breath. After resting for a few minutes, he continued to ask:

"Have you decided on a name for the engine you built? Is it still the name of the mountain? What is it called? Qilian? Hengduan? Nanling?"

"My name is Qilian."

Ye Zhou replied.

"Hello Qilian, hello Qilian, your name is impressive. Come on, Xiaoye, help me up. I'm in good spirits today, so I'll leave you a message."

As he spoke, the old man lifted the quilt and made a gesture to get out of bed. Ye Zhou quickly supported him, and Chen Hao quickly called the nurse to prepare the wheelchair.

Ye Zhou originally wanted to carry the old man directly into the wheelchair, but the latter glared at him, which frightened Ye Zhou and quickly stopped.

In the end, the old man supported the edge of the bed and hobbled into the wheelchair.

He took a deep breath and his body trembled slightly, but his withered hands still rolled the wheelchair firmly towards the study.

Ye Zhou slowly pushed the wheelchair behind him. The old man looked straight ahead and said intermittently:

"Xiaoye, this project of yours is good, very good. You must stick to it. Don't be proud, and don't be discouraged."

"You are going well now. However, you will definitely encounter problems in the future. Don't give up."

“Our generation is getting old, and it’s up to you young people to take the next step.”

"We have struggled for decades to open a road. When we were about to die, we discovered that the road was not opened, but only a few stones were moved."

"However, after moving a few stones, it will be much easier for you to pave the road."

"Xiaoye, I can see that it's not easy for you either. Your hair has turned gray and your eyes are darker than mine. It's been hard lately, right?"

"You keep persisting. Don't blame me. I'm afraid there's only so much I can do for you."

Ye Zhou's eyes heated up, and after a few seconds of silence, he replied in a slightly hoarse voice:

"Old man, you have done enough."

The old man said no more.

After arriving in the study, he stood up tremblingly in front of the desk, picked up the brush that had been prepared, stretched out his hand with difficulty and filled it with ink, and then gently put pen to paper.

His arm muscles have atrophied, and his strength is even so weak that it is difficult to even hang the pen, but he is still slowly and resolutely writing on the paper what is likely to be the last work of his life.

The curving handwriting extends on the paper. The strokes are neither coherent nor smooth, and no sharp edges can be seen.

However, in such a calligraphy that was inferior to that of a primary school student, Ye Zhou could clearly see the strength of an iron horse and the sharp edge that penetrated the back of the paper.

What Tian Tian wrote is a poem.

A poem about Qilian.

In front of the curtain, there are flags and drums in front of the hall, and plum blossoms can be heard everywhere in the flute.

Qin protects the Qiang captains, and the Han family goes out to the fortress with five generals.

The beacon is as bright as the moon under the Qilian Mountains, and the clouds are forming along the Wuding River.

To ask the heroes of Shuofang, how many of them made meritorious deeds at a young age?
