readx;? Zhang Nian saw her staring at herself, and wondered, "What's the matter, Sister Dong?"

Jin Dong'er's eyes paused, and she was amazed, and said, "Xiao Nian, I found that your chest seems to be bigger than before, so you have to have a b." Pen "Fun" Pavilion www.biquge.info"

After taking a bath, I went to my good sister's room, her room was next to it, and naturally I didn't care, I just put on a wide nightdress, empty, her breasts were very soft, in fact, she was very soft, and she was swaying with the movement.

Zhang Nian was ashamed: "Sister Dong will laugh at me, you are only big." ”

After saying that, he fled.

Jin Dong'er lifted her skirt and looked at it, but she was not too happy, she reached out and touched two more handfuls, and said, "Well, it's true that I'm bigger and broad-minded." ”

The interview for the next day is still scheduled in the afternoon, Liu Chen has a habit, after getting up in the morning, his thinking is divergent, he prefers to be free and easy, and he doesn't want to arrange standardized things.

However, he still came to the Jiangning West Road Boss e-commerce headquarters, Cao Rong looked at him and said with a smile: "Yesterday, a group of people didn't go back to sleep, they all worked on the floor in a room next to the laboratory, and now they are working again." ”

"So enthusiastic about work?"

"Yes, seeing that they fought so hard as soon as they came, I didn't dare to be lazy. ”

Liu Chen thought for a while and said: "Now that the fourth and fifth floors are empty, you might as well transform them into dormitories, no one has a relatively independent space, enthusiasm is good, and it is difficult to last if you don't control the rhythm, just use partition cabinets and soundproof cotton, fast, and there is no pollution." ”

"Okay, I'll do it right away. ”

Fang Zhigao hurriedly walked over, the whole person was full of joy, saw Liu Chen, and hurriedly said: "Mr. Liu, I was looking for you." ”

"Yes, the enthusiasm is mobilized. ”

"Hehe, probably every Jiang University engineering man has the potential of geek, last night we had a meeting to discuss, and unanimously decided to develop a model airplane ************ first, one to run in the division of labor of the team, and the other to make up for the shortcomings, Jiang University is still far from here, can you solve the accommodation problem?"

"I want to go together, I have asked Cao Rong to renovate the third and fourth floors, and I can move in tonight, but I think this place is still too noisy, and it may not be conducive to research and development in the long run, and I will start looking for places around me recently. Liu Chen said that Jianghai land is now very expensive, it is not realistic to establish a super logistics center, it is best to take land from nearby, Kuncheng is a good choice, close to Jianghai, and the current development has just begun.

"There's one more thing. Fang Zhigao scratched his head, "I accidentally told you out, several little cubs are clamoring to see you, what do you think of this matter?"

Liu Chen doesn't want others to question anything based on his age, he can't prove it when he meets people, he went to the United States for half a year, and he deeply felt one thing, Americans generally agree that geniuses are different when they are young, so it is taken for granted that young people are outstanding.

And Huaxia, how to say it, there is no hair on the mouth, and if you don't do things well, young people are always considered to be frizzy and can't do good things, and in officialdom politics, this obviously applies.

But in the ever-changing world of science and technology, super gods are often young people, energetic, not too tired to work 20 hours a day, fast to accept new things, strong brain vitality, amazing efficiency, and most importantly, can focus, and have a strong desire to transform the world.

"Then let's go and have a look, Xiao Qian is there too, right?"

"Here, this kid has a hand, is very sensitive to algorithms, and took the lead in solving a few small problems, and a group of high-achieving students from Jiangda are very convinced. ”

Liu Chen and Fang Zhigao came to the laboratory on the third floor together.

Inside was the sound of heated discussions.

"The calculation of rotor aerodynamic parameters is very complex, and the results require high accuracy of the sensor and poor adaptability to the environment. ”

"Mechanistic modeling can reduce the computational cost of parameter identification, and parameter identification can further improve the accuracy of the model. ”

"The lift and moment of the rotor are analyzed by using the leaf element theory, and the dynamic model of the platform mechanism is established by using aerodynamics and Newton's Euler equations, and then the identification tool is used to identify the aerowork parameters with large uncertainties in the frequency domain. ”

Liu Chen saw that there were two built ************ on the middle platform, a model built with a wire shelf, and the motors and rotors were fixed at the four corners. ”

When everyone saw Fang Zhigao coming, they all shouted respectfully.

"Head of the house. ”

"Brother Fang. ”

"Boss. ”

Obviously, Fang Zhigao's technical strength is enough to convince the public.

"Who is this?" muttered to himself, and discussed a few words softly.

Obviously, none of them had seen Liu Chen.

He Qian happily walked over and said, "Brother, you're here, we're working on a small plane, it's fun." ”

Accounts differ and opinions vary.

Shi Sen also looked over curiously.

Fang Zhigao solemnly introduced: "This is our President Liu, and his technical and scientific research attainments are unfathomable. ”

"Not really. Li Lin couldn't help but blurt out directly.

Sure enough, when everyone saw Liu Chen so young, they all showed expressions of disbelief.

Accustomed to it, Liu Chen didn't care about it, and asked Fang Zhigao: "Can the quadrotor fly?"

He blushed and said, "Not yet, it's very complicated, involving the control strategy of the four motors, the remote control, and the communication between each other." ”

"It's so complicated, let's fly first. Liu Chen had a faint smile on the corner of his mouth, measured the weight of the small plane, saw that there was still a little space on the whiteboard, recorded it, started the power supply, and the four stepper motors rotated, increasing the power until the whole plane fluttered and was in a critical state, and the voltage and current values were measured with a multimeter.

Everyone stopped and watched his movements, and during the interview, everyone knew that there was an interviewer with a very poisonous mouth, and when he nagged, Fang Zhigao laughed and said, That's not me, it's all our Mr. Liu asked.

Everyone is holding their breath in their hearts.

Seeing that the person who asked him was so young, he was even more unconvinced and deeply suspicious.

Liu Chen naturally knew what they were thinking, so he didn't care, and then drew a block diagram of a typical PID control on the whiteboard, calculated the parameters according to several measured quantities, and then turned his head and asked Fang Zhigao: "51 for the control chip?"

"Well, there are too many PLC pins, the peripheral circuits are complex, there are very few peripheral circuits of 51 pieces, and they can also directly drive the stepper motor, which is very light in weight, otherwise the power of such a small stepper motor is not enough. Fang Zhigao said and opened the 51 development environment on the computer.

Everyone looked at it curiously, and said in their hearts, can it be done or not? Don't move to a stone and hit yourself in the foot.

Liu Chen held the mouse and quickly dragged it down to check. (To be continued.) )
