What does it feel like for a person to jump 29 times in a row in three days?

Well, standing in the glass elevator, Wu Xiaoqing has the urge to jump down at any time.But every time he had the urge, he would look behind him.

Well, the coach is not here, so don't dance yet.

This is like subconsciously checking whether there are hoops on your feet before jumping bungee jumping.

"Mr. Wu? Do you smoke?"

"Oh..." Wu Xiaoqing subconsciously reached out to pick it up, but waved his hand again, "No, no."

The other party obviously saw Wu Xiaoqing's subtle psychological activities: "Are you quitting?"

"I haven't smoked a few... I can't talk about quitting."

"Then I won't be greedy for you anymore." The other party also put away the cigarette case.

After the elevator door opened, the other party took the initiative to lead the way.The car stopped at the entrance of the hotel, the other party drove the car himself, and Wu Xiaoqing sat in the co-pilot.When the car started, Wu Xiaoqing asked the time: "How long will it take?"

"Half an hour, soon."

"Well, drive slowly, don't be in a hurry," Wu Xiaoqing said, "Has the information been released? Let me take a look."

"It should be sent... Well, why don't I rush."

"No, no, no," Wu Xiaoqing turned on the phone, and saw clearly that there was an email in the mailbox, "It's here, drive hard, I'll check the information."

The car suddenly fell silent.

Wu Xiaoqing opened the email, and the content inside was like a bible to Wu Xiaoqing—it was all in English.

Wu Xiaoqing may not even be able to recite the 26 English letters smoothly.

Fortunately, the English on the mobile phone, after being translated by the search and rescue team and through the glasses, directly becomes a large paragraph of Chinese.

But even in Chinese, Wu Xiaoqing had a hard time reading it. Not to mention understanding the meaning of the whole article, just a single word or word in it can make Wu Xiaoqing's whole head bewildered. ——For a junior high school student to read a thesis of a doctorate in aerospace in the United States, it is indeed a bit cruel to the brain.

"You bought the patent from the United States?"

"This is the basis, and we improved on this basis. The paper has not been published yet, and once it is published, it cannot be kept secret. The patent belongs to our factory."

"Are you supplying exclusively to the aerospace sector?"

"Correct."

"Not confidential?"

"No secrets involved. Many things in the aerospace field are now commercialized. Even rocket engines are not secrets. Doesn't the United States still have SpaceX? It is better than the government. Ours is no problem, at most it is just Compatible."

"What is the difference between your technology and that of the Americans?"

"Well, the battery life is standardized, and it can be increased or decreased as needed..."

"...Well...Let's put it this way, American-made products are custom-made products from the factory. It is a bit troublesome to fill it up once and refill it when it runs out."

"They use high-pressure nitrogen. The advantage is safety. The disadvantage is that it is too troublesome to charge and release, and the battery life is short."

"It is very troublesome to increase the endurance of nitrogen cylinders. They cannot share one gas port, because they are high pressure and are prone to failure. This severely limits the time and scope of space operations."

"Our products are standardized, and the principle is to generate gas by chemical reaction. The compound itself is not nitrogen, and there is no requirement for storage, so it is much more convenient."

Although the other party is just a business manager, when it comes to specific technologies, he still speaks clearly.

Of course, even if he babbled nonsense, it wouldn't affect the effect.

Wu Xiaoqing was already lost in the sky when he was halfway through speaking.

"By the way..." Probably aware of Wu Xiaoqing's distraction, the manager changed the subject: "Can I ask, what unit do you work for? Is it a government order?"

"Oh, no," Wu Xiaoqing said, "It's for making movies."

"Make a movie? Don't you use props to make a movie? Is it necessary to use such an expensive real thing?"

"Space movies, buy a batch of real goods as props, the texture is stronger."

"Props are okay, but the environment can't be simulated, right?"

"Hehe." Wu Xiaoqing smiled.

"Sorry, look at my mouth..."

"However, you guys are really awesome," the manager gave Wu Xiaoqing a thumbs up and said, "Just four backpacks are worth millions, and your crew is really willing to pay."

"Movies, you're not afraid of burning money," Wu Xiaoqing said, "Anyway, it's the investor's money. But you can't discount the quality a little bit, and the director may actually send your equipment to space to shoot a few shots."

"No, don't worry. Whether you are making a movie or actually going on a rocket, we guarantee that there will be no mistakes in the things that come out of our factory. It is stated in the contract-if you are worried , we can also find the insurance company.”

"That's unnecessary. Domestic insurance companies probably don't do this either."

"It's okay to go abroad. If there is an insurance company, we can also give a little discount on the price-this can be used for publicity..."

While speaking, the car arrived at the place.

It was an industrial area in Ningzhou. The car finally drove into a factory called Jingye Chemical. Wu Xiaoqing followed the manager out of the car and walked all the way to the office building.

Wu Xiaoqing’s impression of the chemical plant is still in a chemical park near Dayang Village—the pungent smell can be smelled everywhere, and sometimes at night, when the wind direction is wrong, people will be awakened by the smell.

However, the chemical industry here is obviously very different. There is no peculiar smell in the air. Along the way, you can't see those huge pipes and reactors, and you can't even see a smoking chimney.

After walking into the meeting room, Wu Xiaoqing took the initiative to ask: "Can you give me a computer? I want to see the design drawing."

The computer was quickly brought over, and Wu Xiaoqing quickly opened a software on the desktop and the attachment file in the email just now according to the prompt of the search and rescue team.After opening it, he saw a complex three-dimensional structure appearing in the software.

Wu Xiaoqing, the commander of the search and rescue team, rotated the picture and enlarged certain parts.Just as Wu Xiaoqing was awkwardly operating the interface of the unfamiliar software in front of him, a stranger's voice came from behind him: "Select first, then hold down the left button and drag."

Wu Xiaoqing turned around and saw a thin middle-aged man.She doesn't look very good, with bumps on her face and wearing a pair of glasses.

"Mr. Wu, hello, I'm Xu Chang, the designer of this backpack."

"Oh, hello, please sit down."

"Aren't you going to look at the product first?" Seeing Wu Xiaoqing's blunt movements just now, Xu Chang felt that he couldn't talk about anything in front of the computer. ——I heard from Manager Qian that the young man in front of me is still the boss of the company—then it is even more impossible to have any common language.Xu Chang is not good at persuading customers with his mouth, data and physical demonstrations are his strengths.

"No hurry," Wu Xiaoqing stretched out his hand and pointed to the design drawing on the computer, "If your model is made bigger, how will you solve the problem of stability?"

"How big?"

"Two tons, how about it?"

Xu Chang watched Wu Xiaoqing's eyes change several times: "Two tons? Is it used to transport goods?"

"The transporter."

"That efficiency is not cost-effective."

The product Wu Xiaoqing is looking at now is used in space. It is a jet backpack for astronauts to use when they are acting alone outside the space station. Generally, it can carry a maximum of a dozen kilograms.If there is an important task to go out of the warehouse, it will be hundreds of kilograms at most-this amount is already quite a lot.Continuing to increase this number can certainly increase the maneuvering distance and range of astronauts outside the cabin, but the efficiency has also begun to be greatly reduced-most of the propulsion power is wasted on the propellant itself, not on the astronauts.

"Only look at the range, not the efficiency. Two tons is the basis. If you add more, your design model will have a big change...from a backpack type to a flying carpet type."

"Flying carpet type?" Xu Chang stared at his design drawing for a while, and soon understood Wu Xiaoqing's meaning, "Yes, yes...Actually, rockets can also be used."

"The stability of the rocket type is a big problem. At present, your control accuracy is difficult to achieve."

Although Wu Xiaoqing said the words word by word from his own mouth, he didn't understand what these words really meant.

However, Wu Xiaoqing could see that after he had finished speaking, the designer on the opposite side looked at him eagerly, then took the computer in front of him, and started to draw a new picture in front of him. design sketches.

"The idea is probably like this, but the specific data needs to be optimized by you. How long will it take for you to get something like this out?"

"If this design is used, every backpack... no, every flying carpet! This name is better! The weight will exceed four tons... Does the rocket have so much spare payload?"

"The load of the rocket is not important, we are just here to make a movie, the effect is the first."

Xu Chang patted his head: "I forgot that you are making movies... Yes, the weight is not important, but the effect must be top-notch. In space, this thing can definitely be regarded as a Ferrari!"

"It is indeed a Ferrari...the price is probably more expensive than a real Ferrari."

Manager Qian, who picked Wu Xiaoqing over, also sat next to him at some point, and immediately took over the conversation after hearing this: "No, Mr. Wu, let me do the math, such a... um, a gravity-free flying machine, the cost is not high. It will exceed 200 million."

"Oh, this is more than 30 times heavier than the original requirement." But the price is only less than six or seven times more expensive.

"That's not how the price is calculated... The main cost is the airway design and the gas storage tank. If these things are made into a backpack, they will be more expensive than a car. Made into a car... well, the flying carpet This model can also relax a lot in terms of material requirements.

Wu Xiaoqing nodded and said, "Then... that's it for today. How long does it take for the design drawings to come out? I'll take the drawings and ask someone to do an analysis. After passing them, we can sign the contract."

Xu Chang thought about it seriously: "A week... I haven't had much contact with it before, so I don't know the bottom line."

"It's a little longer." Wu Xiaoqing looked at the subtitles, and his expression suddenly changed—this shows that the search and rescue team will soon be able to arrange them to perform new tasks.

"Five days!" Manager Qian, who was always paying attention to Wu Xiaoqing's face, immediately made a decision: "Working overtime, I should be able to get out."

"Just a week... don't worry," Wu Xiaoqing said, and then he took out a small card from his pocket and handed it to the other party, "This is my business card. After the design drawing comes out, I will contact you as soon as possible." Get in touch, anytime."

Half an hour later, Manager Qian, who had just sent Wu Xiaoqing out of the factory, returned to the conference room. Seeing that Xu Chang was still staring at the design drawing on the computer, he patted him on the shoulder: "What's wrong? Is there any problem?" ?”

"No, no." Xu Chang shook his head, but his eyes still did not leave the design.
