By the time the Entity List fever subsides, it will be almost the end of September.
Zhou Yan originally planned to go there temporarily and pick up his old classmates who were already on vacation. However, he never thought that Lao Yan Yan Wentao would start calling on the 26th, asking him to come over and help.
However, by the time the airline contacted us about the route, it was already the night of the 27th, so we could only leave on the morning of the 28th.
But as soon as he arrived at the departure hall with his wife, another call came after him.
"Fortunately I haven't boarded the plane yet!" Zhou Yan took out his phone and took a look. It was an old acquaintance Yang Yuning calling.
"Hey, Lao Yang, what's the matter with calling so early?"
"Zhou Yan, do your company's flights fly to Jincheng?" Yang Yuning asked Zhou Yan, who was confused by the question. He was stunned for a while before replying, "This is possible!"
"Don't bother me. An old colleague of mine, a teacher at our school, has an elderly man at home who is critically ill. He has not bought a ticket and needs to rush to Jincheng immediately. Can you arrange some seats there?"
"How many people?" Zhou Yan raised his head and glanced in the direction of the tarmac.
"Four, a family of four!"
"There happens to be a flight to Jincheng Zhongchuan Airport. It takes off at 9:30 and goes to the VIP waiting room of T2 terminal."
He hung up the phone, glanced at his curious wife, and smiled: "There is a teacher at school who needs to go to Jincheng for something urgent. He didn't buy a ticket, so Yang Yuning came to find him..."
People were coming and going in the terminal hall, one plane after another took off, and one plane after another landed.
At around 8:50, Zhou Yan's cell phone rang again in his pocket.
"Hello, hello, I'm already here..."
As he said that, the caller waved his hand.
"I saw it," Zhou Yan waved to the figure waving outside the door, "Come in quickly!"
When he walked in, Zhou Yan discovered that the person taking the "lobby" was an acquaintance, Professor Hu Zhongxuan, who teaches space physics at Shouhang.
"Teacher Hu!"
"Teacher" in the university is not just someone you call casually. When Zhou Yan said "teacher", Hu Zhongxuan on the other side was a little surprised: Mr. Zhou, a rich man from Shouhang, had actually studied in his own department.
"Zhou Yan, I didn't expect that the acquaintance Lao Yang mentioned was you..."
The two of them were just about to exchange a few words when the ground staff suddenly walked in: "Mr. Zhou, the Goose Airlines flight took off early. Is it going to take off early here too..."
"Teacher Hu, let's talk after we get on the plane. Give me your luggage..."
Except for the departure hall, Hu Zhongxuan found that the boarding process here was different. After the ground staff's commercial vehicle picked up the passengers, they went straight to the plane.
After seeing the plane clearly, Hu Zhongxuan was a little surprised. He looked at Zhou Yan, who was sitting in the co-pilot: "Zhou Yan, you... we..."
"My partner and I happen to be going to Jincheng..."
After boarding the plane, Hu Zhongxuan found that the decoration of the plane was far from the legend: it was not splendid, nor did it have high-end furniture decoration, it was completely comfortable.
"There are just six of us. Let's take any seat. We are about to take off. Fasten your seat belts first..."
After the flight became stable, a group of people unbuckled their seat belts at the captain's prompt.
"By the way, Teacher Hu, have you had breakfast?"
"Eat..." Hu Zhongxuan casually picked up the magazine on the bookshelf, took a glance at it, and found that it was a foreign aerospace journal, and there were signs of flipping.
"Ruoshu, go to the kitchen to get some drinks and snacks." Zhou Yan looked at the journal in Hu Zhongxuan's hand with a smile, "This is for the first half of September, the second half of the journal has not been mailed yet..."
"You have a wide range of knowledge..." Hu Zhongxuan opened the magazine and browsed it briefly, and found that there were heavy traces of reports about rocket recovery. After thinking about it, he raised his head and looked at Zhou Yan with a smile, "What do you think of Iron Man?"
Recycling rocket project?”
"It feels a bit indifferent," Zhou Yan smiled, "According to the Tsiolkovsky equation, the final speed of the rocket is proportional to the ratio of the initial and final speeds. Reserving a part of the fuel for recovery will inevitably affect the rocket.
Promote efficiency..."
"But..." Hu Zhongxuan smiled and nodded, "The mainstream conclusion at the wedding is that it is quite cost-effective to sacrifice part of the speed in exchange for an economical model that can be reused..."
"Then why not recycle it after the rocket boost is over and the fuel is exhausted?" Zhou Yan was happy, "You know, the safety of recycling will be higher at this time..."
"This is impossible, I have no motivation..."
Yes, it's exactly what you guessed.
"Just install a positioning and deceleration device and capture it before landing..." Zhou Yan smiled and said his solution, "Or improve the hydrodynamic properties of the rocket body and let it land in a specific area..."
Hu Zhongxuan smiled and nodded: "It is indeed a good idea."
"Of course, in my personal opinion..." Zhou Yan smiled and picked up the drink and handed it to Hu Zhongxuan's son and daughter, "Come and have a drink."
"Thank you brother!"
"Thank you brother!"
"In the future, for interstellar travel with the planet as the station, rockets should be abandoned. After all, from the surface of the planet to the synchronous orbit, the economics of this thing are too poor."
"Orbital elevator?"
Zhou Yan was a little surprised: "Teacher Hu, have you ever studied this?"
"The prerequisite for large-scale interstellar immigration should be the geosynchronous orbital elevator." Hu Zhongxuan opened the conversation, "Although the orbital elevator project is huge, the real technical problem is only the weighing materials of the elevator. How to ensure that
The material can withstand the weight of an elevator that is 300,000 kilometers long.”
"Erect the anti-gravity mechanism in sections," Zhou Yan thought carefully. "Hall thrusters are used in outer space, magnetic levitation is used in the atmosphere, and the load-bearing body will most likely be a composite material based on carbon fiber..."
"I heard that you built a carbon fiber factory in the cloud?" Hu Zhongxuan's eyes lit up, "What level can it reach?"
"Only at the aviation level," Zhou Yan looked at the young lady and the girl who were feasting with a smile, "Only when the technology matures in the future will it be possible to further improve the quality..."
This chapter is not over yet, please click on the next page to continue reading! "Alas..." Hu Zhongxuan sighed, "Alas, speaking of which, I have to thank you!"
Zhou Yan was confused by this sentence: Where did Xie come from?
"During the Mid-Autumn Festival, I gave my mother a Yunmai wristband. I didn't care about it at first. When I checked the data a few days ago, I found something wrong, so I sent my mother to the hospital..."
Hu Zhongxuan let out a long sigh.
"This investigation revealed that there is a problem. There are problems all over the body, middle stage lung cancer, nephritis..."
"Oh," Zhou Yan nodded thoughtfully, "The heart, liver and brain should be fine, right?"
"Well..." Hu Zhongxuan nodded, "What a blessing among misfortunes!"
"Lung cancer in the middle stage and nephritis still have a high chance of recovery. Don't worry too much. Besides, if you are worried about the medical level in Jincheng, you can take my aunt to the capital..."
"Thank you for your good advice!" Hu Zhongxuan thought for a while, "I heard from Yang Yuning that Yunmai also does medicine?"
"Mainly medical devices, quantitative and qualitative Chinese medicines and Chinese patent medicines!"
"Someone needs to do these basic things..." Hu Zhongxuan said with deep emotion.
"Well," Zhou Yan nodded and thought for a while, "Teacher Hu, I plan to sponsor a competition in our school."
"what match?"
"Regarding the design of the future space living space," Zhou Yan thought for a while, "it is roughly divided into three groups. The first group is the space station, the second group is the large space living circle, and the third group is the alien planet ecosystem...
…”
"This proposition..." Hu Zhongxuan smiled bitterly and shook his head, "Although Xinghan and Qingyan are not short of money, you can expand such a high proposition..."
"Sooner or later, someone needs to do it, even if it's just to popularize science..."
Hu Zhongxuan didn't take it seriously.
Although Zhou Yan is known as a rich man within Beijing Capital Airlines because he has sponsored many scholarships, no one will look down upon him, especially after being included in the entity list: to be able to open such a large business, no matter the technical investment,
