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

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

Well, the coach isn't there, so don't jump yet.

It's the same as subconsciously looking for hoops on your feet before jumping a bungee jump.

"Mr. Wu? Do you smoke? ”

"Oh......" Wu Xiaoqing subconsciously reached out to pick it up, but waved his hand again, "Don't smoke, don't smoke." ”

The other party obviously saw Wu Xiaoqing's subtle psychological activities: "In the ring? ”

"I haven't smoked a few either...... There is no precept. ”

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

After the elevator door opened, the other party took the initiative to lead the way in front. The car was parked at the door of the hotel, the other party drove in person, 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, open it slowly, don't be in a hurry," Wu Xiaoqing said, "Has the information been sent?" Let me see. ”

"It should have been posted...... Well, I'll rush it. ”

"No, no," Wu Xiaoqing opened his mobile phone and clearly saw that there was an email in the mailbox, "It's here, you drive well, I'll take a look at the information." ”

There was a sudden silence in the car.

Wu Xiaoqing opened the email, and the content in it was a book from heaven to Wu Xiaoqing - it was all in English.

Wu Xiaoqing is estimated to not even memorize the twenty-six English letters.

Fortunately, the English on the mobile phone, after the translation of the search and rescue team, through the glasses, directly became a large section of Chinese.

But even in Chinese, Wu Xiaoqing is quite difficult to read, not to mention understanding the meaning of the whole article, just the individual words and words in it can make Wu Xiaoqing's whole head cloudy. - Asking a junior high school student to read a doctoral dissertation in aerospace is indeed a little cruel to the brain.

"You bought the patent from the United States?"

"That's the foundation, and we're improving on that. The paper hasn't been sent yet, and if it does, it can't be kept secret. The patents are our own. ”

"Are you specifically supplying to the space sector?"

"Yes."

"Not secret?"

"It's not secret, now a lot of things in the aerospace field are commercialized. Even if it's a rocket engine, it's not a secret, doesn't the United States still have a spaceX? It's better than the government. We're even more fine with this, at most it's just a match. ”

"What's the difference between your technology and the Americans?"

"Well, the range is standardized, and you can increase or decrease the ...... as needed"

“…… Not...... Let's put it this way, what the Americans make is the factory's customized goods, which are full at one time and can only be flushed again when they are used up, which is a bit troublesome. ”

"They use high-pressure nitrogen, which has the advantage of safety, but the disadvantage is that it is too troublesome to flush and discharge, and the battery life is short."

"It is very troublesome to increase the battery life of nitrogen cylinders, and they cannot share a gas port, because it is high pressure and it is easy to fail. This severely limits the time and scope of space operations. ”

"Our products are standardized on the principle that gas is produced by chemical reactions. The compound itself is not nitrogen, and there are no storage requirements, so it is much more convenient. ”

Although the other party is just a business manager, when it comes to specific technologies, he still talks about the first thing.

Of course, even if he talks nonsense, it won't affect the effect.

Wu Xiaoqing was already out of the world halfway through his words.

"By the way......" probably noticed Wu Xiaoqing's distraction, and the manager changed the subject: "Can you ask, what unit are you from?" Is it a government order? ”

"Oh, no," Wu Xiaoqing said, "for filming." ”

"Making a movie? Don't you all use props when making movies? Is it necessary to use such an expensive real guy? ”

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

"It's okay to say that the props can't be simulated in the environment, right?"

"Huh." Wu Xiaoqing smiled.

"I'm sorry, but I have a lot of mouths......"

"However, you guys are really," the manager gave Wu Xiaoqing a thumbs up, "Just four backpacks, it's millions, and your crew is really willing to pay." ”

"Movies, don't be afraid of burning money," Wu Xiaoqing said, "Anyway, it's the investor's money." But you can't discount the quality at all, and the director may really send your equipment to space to shoot a few shots. ”

"No, don't worry. Whether you are making a movie or really getting on a rocket, what comes out of our factory, I guarantee that nothing will go wrong. It's all written in the contract – if you're not sure, we can go to the insurance company. ”

"That's not necessary, and domestic insurance companies probably don't do this."

"You can also find foreign countries, and if you have an insurance company, we can also give a little discount on the price - this can be used for publicity......"

As he spoke, the car arrived at the place.

It was an industrial zone in Ningzhou, and the car finally drove into a factory called Jingye Chemical, and 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 stuck in a chemical park near their village of Dayang — pungent smells everywhere, and sometimes at night, when the wind is not in the right direction, people will be woken up by the smell.

However, the chemical industry here is obviously very different, there is no smell in the air at all, and along the way, you can't see the huge pipes and reactors, not even a smoking chimney.

After walking into the conference room, Wu Xiaoqing took the initiative to ask, "Can you give me a computer?" I'd like to see the blueprints. ”

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

Wu Xiaoqing, the commander of the search and rescue team, rotated the picture and enlarged some 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: "You have to select it first, and then hold down the left button and drag." ”

Wu Xiaoqing turned around and saw a thin middle-aged man. The appearance is not very good, the face is pitted, and he is wearing a pair of glasses.

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

"Oh, hello, please take a seat."

"Why don't you go and see the product first?" Xu Chang saw Wu Xiaoqing's blunt action just now, and felt that he couldn't talk about anything in front of the computer. - Listening to Manager Qian say that the young man in front of him is still the CEO of the company - it is even more unlikely that there is any common language. Xu Chang is not good at convincing customers with his mouth, and data and physical demonstrations are his strengths.

"Don't worry," Wu Xiaoqing stretched out his hand and pointed to the design drawings in the computer, "Your model, if it becomes bigger, how to solve the stability problem?" ”

"How old?"

"Two tons, how's that?"

Xu Chang looked at Wu Xiaoqing's eyes and changed several times: "Two tons? Is it used to transport goods? ”

"Transporting people."

"That's not cost-effective."

The product that Wu Xiaoqing is looking at now is a jet backpack used by astronauts in space outside the space station when they act alone, and they generally carry a maximum of more than a dozen kilograms. If there is an important task out of the warehouse, it is at most hundreds of kilograms - this amount is quite a lot. Continuing to increase this number will certainly increase the distance and range of astronauts outside the capsule, but it will also begin to be less efficient – most of the propulsion power is wasted on the propellant itself, not on the astronauts.

"Just look at the range, not the efficiency, two tons is a basis. If you add more, your design model will be overhauled...... From a backpack type to a flying carpet type. ”

"Flying carpet?" Xu Chang stared at his design for a while, and quickly understood what Wu Xiaoqing meant, "Yes, yes...... Actually, rockets can too. ”

"The stability of the rocket type is a big problem, and it is difficult for you to do the control accuracy at the moment."

Although the words came out of Wu Xiaoqing's mouth word by word, he didn't understand what these words really meant.

However, Wu Xiaoqing could see that after he said these words, the designer opposite looked at him eagerly, and then took the computer in front of him and began to draw a new design sketch in front of him.

"The idea is probably like this, but the specific data needs to be optimized. It's going to take you a long time to get something like this. ”

"If you go by this design, every backpack ...... No, every flying carpet! The name is better! It will weigh more than four tons...... Does the rocket have so much excess load? ”

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

Xu Chang patted his head: "I forgot that you guys are doing movies...... Yes, the weight doesn't matter, but the results are definitely top-notch, and in space, it's definitely Ferrari-class! ”

"It's a Ferrari indeed...... I'm afraid the price is even more expensive than a real Ferrari. ”

Manager Qian, who took Wu Xiaoqing, didn't know when he was also sitting next to him, and immediately took over when he heard this: "No, Mr. Wu, I calculated it, such a ...... Well, a gravity-free aircraft will not cost more than two million. ”

"Oh, that's more than thirty times heavier than the original request." But the price is less than six or seven times more expensive.

"That's not how the price is calculated...... The main costs are airway design and gas storage. If these things are made into a backpack, they are more expensive than making a small car. Make a car ...... Well, the flying carpet is a model that can also relax a lot in terms of material requirements.

Wu Xiaoqing nodded, and said, "That...... That's it for today, how long will it take for the design drawings to come out, and I will take them to someone for analysis, and after they are passed, we can sign the contract. ”

Xu Chang thought about it seriously: "A week...... I haven't had much contact with it before, and it's a bit bottomless. ”

"It's a little longer." Wu Xiaoqing looked at the subtitles, and his face suddenly changed - this shows that the search and rescue team will soon be able to arrange for them to carry out a new mission.

"Five days!" Manager Qian, who always paid attention to Wu Xiaoqing's face, immediately clapped: "If you work overtime, you should be able to get out." ”

"Just for 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 comes out, contact me as soon as possible, no matter when." ”

Half an hour later, Manager Qian, who had just sent Wu Xiaoqing out of the factory, returned to the conference room, and saw that Xu Chang was still in a daze at the design drawings on the computer, and patted him on the shoulder: "What's wrong?" Any questions? ”

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