Time flies.
In the blink of an eye, three days have passed.
Chengdu, Shuangliu Airport, the top international airport in Southwest China.
As the largest international top airport in Southwest China, with an average daily passenger throughput of more than 100,000, Shuangliu Airport is at its busiest at all times.
The flights or planes belonging to different airlines are like an endless stream, rising and falling, majestic and majestic.
Dragging his suitcase, holding a ticket in his hand, Zhou Hai, wearing a simple light blue shirt and shorts, stood in the spectacular lobby of Terminal 2, with a high-spirited face and a faint smile like a spring breeze.
With eyes wide open, everyone stood in line quietly waiting to check in.
Destination, the capital!
In these three days, Zhou Hai lived a happy and beautiful life.
On the first day after receiving the school bonus, Zhou Hai went to the vegetable market to buy a full 30 kilograms of beef, spending more than 900 yuan, and ate a nutritious and delicious super beef meal.
Later, Zhou Hai added not only beef, pork, chicken and fish to his recipes, but also vegetables and fruits containing various vitamins and nutrients to fully supplement the body's needs.
The days are comfortable and at ease.
Yesterday, I filled out my college entrance examination application choices, which were approved in advance. My first choice was the Air Force Aviation University, and my second choice was the Lianda Naval Academy. The remaining four fields were left unfilled.
Today, Zhou Hai received a bonus of 100,000 yuan from the Old City Education Bureau on his bank card.
Have money in hand and a strong waist.
Zhou Hai did not hesitate to abandon his original plan of running a regular-speed train, and with a wave of his hand, he bought an economy-class ticket from Chengdu to the capital on China Southern Airlines, spending a cool 1,860 yuan.
1,860 yuan is equivalent to sixty pounds of beef.
To be honest, after buying the ticket, Zhou Hai's heart ached a little.
Considering that this was his first time flying, the pain in Zhou Hai's heart disappeared.
Standing quietly at the back of the team, Zhou Hai was getting ready, and he was already slightly looking forward to it.
"Zhou Hai, you didn't even tell me before you left?" At this moment, a familiar voice suddenly came from behind, his words were clear and full of resentment.
After hearing this, Zhou Hai turned around with a smile like a spring breeze and stared at Zuo Xue, who stood as graceful as an orchid in front of him: "I told you, I sent you a text message three hours ago, but I know you are very busy, so I didn't." disturb."
She wears a light white dress, white shoes, and a cute Korean-style bun with fluffy hair that falls slightly on the side of her face. She has a delicate face with a round of light makeup, which perfectly highlights her beauty.
"Hey, this girl is so beautiful. This boy is so lucky."
A middle-aged woman standing in line to check in was stunned for a moment when she looked at Zuo Xue, who was wearing a light white dress.
"You know, I'll come over even if I'm busy." A slight smile appeared on Zuo Xue's face, and his eyes were clear and bright with a hint of agility.
Zhou Hai smiled and shook his head, looked at Zuo Xue in front of him, and said softly: "Thank you, the time is coming, I should go."
After saying that, he was about to turn around and check the tickets.
It was late, and there were only a few minutes left before the last check-in time before the flight took off.
"Why don't you give me a hug before we say goodbye? I like something more romantic." Just when Zhou Hai was about to turn around and leave, Zuo Xue stared at him and shouted softly.
Zhou Hai froze for a few seconds, then turned around and looked at Zuo Xue, who had a smile on his face.
"Then, be more romantic." Taking a deep breath, Zhou Hai smiled slightly and walked towards Zuo Xue.
Zuo Xue's smile continued, and the two of them gently opened their hands and held each other in each other's arms.
Hugs, warmth.
The romance before parting belongs to the romance between friends.
After a gentle hug, Zuo Xue trembled in her heart, with a forced smile on her face, and waved goodbye: "Be safe, Zhou Hai."
"Goodbye, Zuo Xue, I'll contact you later." Zhou Hai waved his hand with a carefree expression, turned around and walked towards the ticket gate.
Check in and board the plane.
Seeing off, farewell.
To Zuo Xue, it seemed that he was the only one left in the huge terminal.
"May you be well."
Quietly watching Zhou Hai's retreating figure, Zuo Xue stood on the spot and murmured softly.
Zhou Hai left the terminal building slowly, entered the airport along the boarding gate, and boarded the scheduled flight.
This flight was a China Southern Airlines A330-300 medium-to-long-range wide-body passenger aircraft numbered MU3578.
"Groan!"
Soon after, with the roar of two Pratt & Whitney PW4168 high-bypass aviation turbofan engines, there was a roar that echoed through the sky. The flight, which had received permission from the tower to take off, slowly taxied into the main airport under the control of two civil aviation pilots, the first and second officer. track.
The high-performance wear-resistant tires rolled at high speed and came into close contact with the airport's main runway. As the power output of the two aviation turbofan engines became higher and higher, the take-off speed of the entire flight continued to increase.
"Buzz!"
As the fuselage bumped slightly, the A330-300 medium-to-long-range wide-body passenger aircraft dressed in red head and white body, like a noble and proud white swan, jumped slightly, broke away from the constraints of the main runway of the ground airport, and pointed straight into the blue sky in the distance.
"Feeling average."
Zhou Hai, who was sitting in the economy class cabin by the window, felt a little disappointed after experiencing the entire process of taking off a commercial airliner.
Slow, smooth, slightly bumpy, nothing like you expected.
If the engine can be operated at full load to output power, the passenger plane can take off at high speed, climb at a large angle, or even flip and fly upside down, the ticket price will definitely be worth it.
Of course, Zhou Hai knew that his crazy idea would not be realized.
If such a situation were to happen, and there was no cover for reasons such as aircraft malfunction, the captain and co-pilot would probably be inundated with complaints from passengers and verbal abuse from leaders. They would be laid off and have their driving licenses revoked as the lightest punishments.
Zhou Hai threw away some crazy thoughts in his mind and looked around. Every passenger was either chatting or sleeping. Several others were pale and seemed to be about to vomit. There were three young people resting with their eyes closed next to them. , one male and one female.
After casually looking at it, Zhou Hai withdrew his gaze, took out the books he carried with him, and read them silently.
"Fundamentals of Parallel Programming for Computational Aerodynamics" is one of the advanced books in the field of aerodynamics. The main aspects of this book are: starting from the basic assumptions, deriving computational aerodynamics in more detail. The equation form and solution process suitable for programming in the coordinate system.
Briefly summarized, as the name suggests, it uses mathematics to perform in-depth and detailed calculations of aerodynamics and derives it programmatically.
The author of this book is Liu Wei, a senior professor of aerodynamics, and it is published by the National Defense Industry Press.
The entire book is full of dazzling formulas and verification processes. It is complex and tedious, but it only touches the surface and does not go deep into the core. Many important things are missing.
