The rookie team of Dream Science and Technology Building, Wang Yinan decided to stay up with them for a few more days, if there are those who can't withstand the pressure and loneliness to quit, they don't force it, the big waves are sweeping the sand, and those who are left should be dead-eyed, and it will be easier to train in the future.

Determining the direction of future computer investment, Wang Yinan felt that he had no ability to change anything, and deep down, he did not feel that it was a mistake to choose the direction of quantum computers, "just a little later in the time to produce results", Wang Yinan said to himself, "Maybe ten or twenty years later, a new generation of computers will be born in their hands."

As a vague leader in superconducting computers, Wang Yinan talked about using the low power consumption of superconductivity and some physical effects to improve the existing architecture through two phone calls with Professor Li of the National University of Defense Technology.

For the two-day meeting, the two also reached a tacit understanding, we will not interfere with the choice of the direction of quantum computers at the overall level, but how can eggs not be put in one basket, but also to maintain sufficient investment in the traditional architecture.

On this afternoon, after taking an open class at Imperial Capital University, Imperial Capital University has a tradition of open classrooms, and even people from outside the university can come in to listen to the lectures at any time, and Wang Yinan's class is the most popular course among students, and there is no one, so every time Wang Yinan's lecture is arranged in the largest lecture hall, it is not an open class but also an open class.

Wang Yinan came to the carving time, Zhou Hui had been waiting for him unhappily for a long time, Wang Yinan coaxed for a while, Zhou Hui was still sullen, "I've been bored lately, and there is no notice, so you can't spend more time with me?" ”，

Wang Yinan had an idea, maybe he could do this, "Then let's go out and play, there is a gift for you",

"Okay, okay, where are you going? What gift? Zhou Hui asked,

"Let's go to Jinling first, gifts, it won't work if you say it, follow me and see how a miracle is born", Wang Yinan said very confidently,

After all, the main members of the laboratory are in N University, or in Jinling, and Wang Yinan really needs to run is Wang Yinan himself, the imperial capital has a direct high-speed rail from Jinling, more than three hours by car, it is still very convenient.

After coming to Jinling, Wang Yinan first accompanied Zhou Hui to climb the Purple Mountain, to see the weather of the ancient capital of the Six Dynasties, and in the evening, he ate the famous duck blood vermicelli soup in Jinling, as well as the soup dumplings of the Dingshan Hotel, Zhou Hui was full of praise for eating, it seems that the Jiangnan woman is still more suitable for the taste of Jiangnan.

Wang Yinan originally asked Zhou Hui to go back to rest by herself, but she had to follow her to the laboratory to see, saying that she wanted to know how the gift was born, Wang Yinan always said that it was still early and it was useless, so the two of them came to the superconducting motor laboratory of N University together.

When Wang Yinan and Zhou Hui came to the superconducting motor laboratory located in a small science and technology park next to N University, it was already dark, and the laboratory was still in full swing, after all, this is the laboratory of N University alumni and Abel Award winners, and Wang Yinan has always been generous in terms of salary, has face, and is engaged in Bluestar's leading black technology.

The person in charge of the laboratory is called Shen Wei, a master's tutor in his thirties at N University, and he can be regarded as a typical young and promising person, he has been waiting at the door for a long time, and when he saw Wang Yinan and Zhou Hui, Shen Wei hurriedly greeted him, "Professor Wang, the superconducting wire you sent is really easy to use."

Shen Wei took the two of them through the laboratory, Wang Yinan waved his hand to the busy students, said "hard work", and came to the innermost part of the laboratory, in front of a half-assembled motor, several young looking students, were testing a coil wound by a quarter, "This is a high-power superconducting motor, through the results of supercomputing simulation, the final torque and speed will far exceed the best products on the existing market", Shen Wei introduced,

"The most important thing is that the wrapping characteristics of the magnetic field lines are particularly good, and so far, the test value is almost exactly the same as the theoretical value, so we are ready to modify the design scheme later, which can further reduce the overall weight of the superconducting motor."

"Can the torque meet my requirements", Wang Yinan asked,

"Don't worry, only high, not low",

With enough torque, larger propellers can be driven at high altitudes to reach higher speeds, so that stratospheric prowlers can fly more easily.

Wang Yinan looked at the future high-power superconducting motor with satisfaction, which was smaller than he imagined, "How about power consumption", Wang Yinan asked,

"There's no way to estimate it now", Shen Wei said, "but it's definitely very low", after speaking, Shen Wei took out a small cylinder the size of a thumb like offering a treasure, "You can try this to know."

Wang Yinan's eyes lit up immediately, "This is the gadget I asked you to make?" ”，

"Yes, miniature superconducting brushless motor", after speaking, Shen Wei put a bamboo dragonfly on the middle shaft of the small cylinder, and then connected the red and white wires at both ends of the small cylinder to the 12V stacked battery, and then put the small cylinder in a slightly larger shell and semi-fixed, of course, he did not forget to connect a governor in series, "When I tested it for the first time, I didn't connect to this governor, I ran directly at full speed, and I almost didn't hurt anyone", Shen Wei still had palpitations when he said it.

Shen Wei handed the governor to Wang Yinan, "Come on", Wang Yinan took it, thought about it, and handed it to Zhou Hui, "Did you play with bamboo dragonflies when you were a child?"

"Hmm", Zhou Hui nodded, "Slowly turn clockwise to increase the speed, remember not to turn too fast",

Zhou Hui slowly turned the governor, accompanied by a buzzing sound, the bamboo dragonfly rotated, with the increase of current, the bamboo dragonfly turned faster and faster, and finally flew in the air with the small cylinder below, that is, the superconducting brushless motor.

"I heard a very small sound," Wang Yinan said, "mainly wind noise, we didn't test it with bamboo dragonflies, and there was no sound at all," Shen Wei said.

After playing for a while, Zhou Hui returned the governor to Shen Wei, "This is your gift, it's too much", Zhou Hui didn't give Wang Yinan any face,

"Yes or no, this is part of the gift, but only a small part," Wang Yinan replied.

"The gift is born from scratch, little by little, tomorrow we should go to the next stop, that is, the paradise of the entire Blue Star manufacturing industry, Huaqiang, it is not an exaggeration to say, as long as you want to get something, in Huaqiang can be made for you."

"What's the torque of this little thing?" , Wang Yinan asked Shen Wei, "XXX Nm at 5,000 rpm",

Wang Yinan picked up his mobile phone and dialed the phone number of Chief Teacher Yang of 116 Institutes, "Chief Master Yang, I am Wang Yinan",

"Yes, I'm in Jinling, the turbine shape you asked me to calculate last time, is there a result?"

"The result is that the two-stage turbine should have the highest compressed air efficiency and the smallest noise, but the specific shape depends on the performance of the drive motor, mainly torque," said Mr. Yang.

"In terms of performance, you can design it according to the data of XXX Nm at 5,000 rpm."

"I'm X, such a good data, is it using a superconducting coil?"

"Of course, the big guy's data hasn't come out yet, but you just look forward to it", Wang Yinan said proudly,

"Then wouldn't it be easy for our drones to fly to 30,000 meters, and the payload could also be improved", Chief Yang began to calculate.

"You can enjoy yourself slowly, after calculating the shape of the two-stage turbine, you can directly send the CAD drawings and structural strength requirements to this mailbox", Wang Yinan gave Chief Yang an email address, "Can you do it tonight", Wang Yinan asked,

"Your business must be done, and you have to finish working overtime until the early hours of the morning before you can leave", Chief Engineer Yang casually assured,

"Anyway, what are you going to do, such a small size, it doesn't look like it's used on an aircraft."

"Hehe, keep it secret, you'll know when the time comes", after speaking, Wang Yinan hung up the phone.

After chatting with Chief Master Yang, Wang Yinan then dialed the phone,

"Mr. Lu, I'm Wang Yinan",

"The turbine is two-stage, the detailed CAD drawings and structural strength requirements will be sent to your mailbox before going to work tomorrow, the size of the motor you wait", Wang Yinan beckoned, called Shen Wei over, held down the phone and asked in a low voice, "What is the diameter of the little guy?" "Diameter 1.5 cm, length 1 cm", Shen Wei replied,

Wang Yinan picked up the phone and continued, "The length of the motor is 1 cm, the diameter is 1.5 cm, do you hear clearly?"

"I'll repeat the requirements for the module again, and you can see if there are any questions," Wang Yinan said.

"The size of each module is a rectangle of five centimeters by eight centimeters, and the thickness is about two centimeters, and the modules can be freely spliced together to form a whole",

"A two-stage turbine and an electric motor are installed in the middle of the module, and the air intake can be on top of the module, or on the front and rear of the module, and the air inlet can be simply shielded to prevent foreign objects from damaging the turbine."

"Except for the necessary structural framework, the other parts of the module are filled with polymer batteries, which is required to be as light as possible, and how much battery capacity is required," said Wang.

"It is best to make it configurable, how much is the highest, how much is the lowest, and it can be flexibly handled when it is used",

"It's easy, it's too easy for you, but the second half of the module is a big challenge."

"Yes, of course I know it's very difficult, I won't look for you if there is no difficulty, I can do it directly in my garage, no, you are also the most expensive manufacturer in the whole Huaqiang, you get what you pay for",

"I know that the entire Blue Star, except for the Lanxiang Technical School, where the dragon is missing, is the best in your technical strength."

"Yes, there are 160 small tubes in the lower part of each module, that is to say, one every 0.5 centimeters, and the orientation of these small tubes can be adjusted individually",

"Yes, the maximum inclination angle of the front and back, left and right should not exceed 30 degrees."

"What, it's too difficult, well, then no more than twenty-five degrees",

"What, you need a chip on the module, otherwise you can't get it", Wang Yinan thought for a while,

"Okay, it's a prototype system anyway, don't consider the cost for the time being, even if you add an X86 up, I'll admit it",

"No, in this case, do you want to add an industrial control bus", Wang Yinan said,

"It has to be added, otherwise the modules can't be addressed?" ，

"Okay, you're experts in this area, how long will it take for me to listen to you?" ，

"Not for a week, I'm going back to the imperial capital for a meeting in a week, so I don't have time to do this",

"Three days at most, you have done a good job in this, rest assured that the large list of mass production in the future, I guarantee that it is also yours", Wang Yinan was busy drawing a big pie on the opposite side.

To put it mildly, the other side finally agreed to take out something within three days, Wang Yinan turned to Shen Wei, "Within three days, make a hundred gadgets, no problem, right?" ”，

"No problem", Shen Wei looked relaxed, "The most important thing I need here is a scientific research dog",

"That's okay, call me when you're done and ask someone to send it to me, I'll take this first", Wang Yinan put the small motor with the bamboo dragonfly into his pocket.

Seeing that Zhou Hui was already waiting impatiently, Wang Yinan didn't care about cheering up the younger brothers and sisters, so he hurried back to the hotel with Zhou Hui.

"By the way, what are you doing in such a big battle", Zhou Hui still couldn't help but ask,

"Confidential", Wang Yinan replied very badly,

Of course, soon he got his wish.
