Beihang Fifth Department, workshop office.

A group of students sat on the pony, and Professor Hu stood at the back of the students, looking at the blackboard.

"The flying principle of a quadcopter drone is very simple, let's start with a simple vertical take-off and landing." Qin Feng drew a cross on the blackboard, and a circle was drawn on each vertex of the cross, which was crooked and unaesthetic.

"We know that in the design of the helicopter, the offset of rotational torque is very important, and in the quadcopter UAV, the cancellation of rotational torque should also be taken into account, so the propellers on each diagonal rotate in the same direction, and the rotation direction on the two is opposite, such as in my picture, the upper left and lower right corners rotate clockwise, and the other two rotate counterclockwise. For the sake of introduction, I've named them 1, 2, 3, and 4."

1 in the upper left corner, 2 in the upper right corner, 3 in the lower left corner, 4 in the lower right corner, and all four propellers have names.

"Well, so that the whole vehicle can be dynamically balanced, the rotational torque and the gyroscopic effect are canceled out, and the good explanation for the ascent and descent is that, like a helicopter, as long as the four propellers provide more lift than gravity. I'm going to talk about how to move horizontally, which is also called yaw, for example, now I want to move to the right, what should I do at this time? ”

Everyone's eyes widened.

"I just need to increase the revs by 1 and 4!" Qin Feng continued: "Because 1 and 4 are rotating clockwise, they will get a greater torsional moment, and under the action of this torque, the aircraft will rotate in the direction of small torque, that is, the direction of 2 and 3, both of which are rotating clockwise, that is, the aircraft will move to the right, in the same way, if I increase the speed of 2 and 3, it will go to the left, and if I increase 1 and 2, it will go up, I am a plane structure, so the aircraft can move in four different directions by changing different moments." ”

This is a bit difficult to understand, and these people have to think about it.

However, Qin Feng obviously underestimated the IQ of college students, college students in this era are the real pride of the sky, and they can be admitted to Capital University of Aeronautics and Astronautics, which is not much worse than that of Capital University and Tsinghua University.

"In this way, if you want to make this quadcopter rotate, you can increase the speed of two of them to a certain extent, for example, let the torque of 1 and 4 completely exceed the reverse torque of 2 and 3, then this kind of aircraft can rotate and fly in the sky, it should be more beautiful!" A male student spoke.

"It's not just about rotating, it's about pitching or even reversing, for example, by increasing 1 rpm and dropping 4 rpm, by the same amount of change, so that the aircraft rotates around the axis on the other side! You can even keep spinning! Beautiful, I like this flying machine! A male student spoke.

Okay, I only introduced yaw, and these people summed up more ways to play? Qin Feng was very emotional, college students are college students, amazing.

This is how the quadcopter is played, flying horizontally, spinning, flipping around itself, and multiple drones forming a formation to make all kinds of cool actions. Of course, I am even more powerful, after all, I am the one who inspired them.

"In 1907, four years after the Wright brothers invented the airplane, Jacques and Louis worked with Professor Charles Richet to develop a special flying machine that was exactly like your blueprints." Professor Hu spoke: "However, after that, this kind of flying machine quickly disappeared into the long river of history because of its unstable flight. ”

Sure enough, the college students are amazing, and the professor is even more amazing, there is ink in his stomach, and he said the source of Qin Feng's design plan.

When did quadcopter drones start? It wasn't until after the nineties that some people began to study it, and in the new millennium, the technology slowly matured and was actually used, which was already after 2010.

However, if you trace back to the source, the huge quadcopter monster in 1907 was the first quadcopter.

"It's all good to say what the big guy said, but it's not easy to mature this flying machine." Professor Hu continued.

At first, he didn't think about it, but when Qin Feng introduced it, he suddenly found these from his memory, and he also saw the biggest problem with this kind of flying machine: flight control.

If you want to have different flight attitudes, you have to write different flight controllers, which is not as simple as saying a word.

"Yes, it's not an easy thing to do, but that's what we're trying to do." Qin Feng said: "We are lagging behind in many fields, no matter how hard we try to catch up, we are always running behind others, so we have to change the track, this quadcopter has not been involved in anyone for the time being, we will start to study now, then we can break out of the sky in this field!" Our Pacific Group is optimistic about this direction, even if we invest hundreds of millions, we will build this kind of aircraft and bring it to the market! I also welcome all those who have aspirations to join us. ”

Qin Feng looked at the college students below, especially the male and female classmates who had just spoken, they knew everything and obviously had their expertise in this area.

No one will know how big the market for quadcopters is, no one knows that in this field, the East is the hegemon, and now, since Qin Feng has come to this world, he has started the Pacific Group and made a lot of money, of course, he must develop all kinds of civilian products.

If others want to use it in the military, they can't do it themselves, but what our Pacific Group produces is civilian products!

"Sure enough, you young people are courageous, and your Pacific Group is really rich." Professor Hu said: "Mr. Qin, I am afraid that you are not here to ask for help or cooperate, but to dig people, right?" ”

"No, of course it's cooperation." Qin Feng said: "Professor Hu, you also know that our group is engaged in high-tech quadruped robots and human exoskeletons, which is in cooperation with my alma mater, Capital University. ”

The university is good, the university has free talents, free equipment, and various subsystems can be contracted to professors, and even as a graduation thesis topic for college students, although he said that he would invest hundreds of millions, but he still has to save money.

Of course, in order to avoid all kinds of infighting, when cooperating, the Pacific Group requires absolute control, and this cooperation must have a unified voice.

"Mr. Qin, I am willing to join this project!" The male student spoke: "My name is Liu Yang, I am a senior this year, I have been escorted to graduate school, I am thinking about what project to do in graduate school, I am very interested in your quadcopter drone project!" ”

"Mr. Qin, I am also willing to join this project." The female student also spoke: "My name is Hu Miaomiao, I am a graduate student this year, and I have been following Hu ...... Professor Bee 3, I want to develop a more advanced flying machine! ”

Speaking of this, she glanced at Professor Hu with apologies in her eyes.

Hu Miaomiao? This girl can't be Professor Hu's daughter, right? Qin Feng looked at the appearance of the two again, and was even more affirmative, this girl disliked the plane made by her father, just like a big toy, she wanted to be more advanced, she was going to kidnap Professor Hu's daughter, and the other party's mood at this time was ......

Professor Hu sighed: "Yes, our Bee 3 is relatively backward, after all, our Capital University of Aeronautics and Astronautics has limited funds, we want to tinker with advanced aircraft, and we don't have that fund, this quadcopter UAV sounds very good, if you want to join the Pacific Group, then go, I won't stop you." ”

At this moment, Professor Hu's heart was a little lonely.

"Professor Hu, what about you? Don't you want to join us? If you can come to our team, I ask you to be the leader of this aircraft company, how much research and development funds do you want, how much I will allocate to you! ”

"I'm in my fifties......"

"What's wrong with fifty? The last time I met Song Lao, he was also in his fifties, and he was still struggling on the front line, and the old man of the 201 Institute had already retired and was hired back to preside over R&D. Professor Hu, your generation was delayed when he was young, and now he should take the lead while he can still do it! Qin Feng looked at Professor Hu's face and was very sincere: "With your strength, you should definitely not just engage in a few toy-like light aircraft, if you want to do it, we will do a good job!" We plan to develop the kind of air triple jumper, at least a year can sell thousands of units, this kind of quadcopter, after the successful development, a conservative estimate can sell tens of thousands of a year, can be sold to the world, when the time comes, let all peers know that in this field, we are the strongest in the East! ”

Hu Miaomiao secretly gave Qin Feng a thumbs up, well said, it should be stimulated like this, otherwise, his father can't let go of this kind of Bee No. 3, this plane is the same as a toy, can it be used by our university professors?

Let's engage in high-tech!

"Mr. Qin, you just said that you want to jointly engage in this research and development with our Capital University of Aeronautics and Astronautics?" Professor Hu spoke.

"Yes, it will take advantage of the R&D capabilities of our university, and we will provide the funding. The R&D site can be at the university or at one of the premises provided by our group. But production definitely has to be on our side. Qin Feng said: "Moreover, if we cooperate in research and development, our Pacific Group must occupy more than 51% of the shares, these college students can join our group during their school years, become regular employees of the group, and go to college, they can no longer ask for money from home, they have to make their own money, everyone is still in school, tentatively 500 per month, and when they officially join the company after graduation, the monthly salary starts at 2,000, Professor Hu, you are the leader of the project, 5,000 per month." ”

Everyone was shocked.

College students have just graduated and joined the work, counting the 22-level salary, which is equivalent to a section-level cadre, the salary is 56 yuan, and then it will rise year by year, even if the enterprise is good, all kinds of benefits are added together, which is about 100 yuan a month.

I went to work in the Pacific Group, and I was able to get 500 a month while I was still in school! After graduation, two thousand starts, which is definitely a high salary! The 10,000 yuan households in the society are sought after, and for them, it is just half a year's salary.

Mr. Qin is a trench!

"Mr. Qin, I want to join!"

"Mr. Qin, I want to join too!" In an instant, someone shouted again, and those who were still hesitating just now did not hesitate.

In this era, it is rumored in society that it is better to build an atomic bomb than to sell tea and eggs, and many scientific researchers want to live a good life, so they have to go to the sea and become businessmen from R&D personnel, which is a huge waste! Now that Qin Feng is here, let's provide these scientific researchers with the best conditions and let them create the most advanced equipment! If you want to achieve the real development and growth of the country, you can't rely on real estate, you still have to rely on industry and technology!

Moreover, no matter how well it is said, their Pacific Group is a private enterprise, and there is no iron rice bowl, if you want college students to join, you have to open a high enough salary!

Professor Hu shook his head: "Mr. Qin, I gave me too much, I only need to take the school's salary, I can't ask for 5,000 yuan a month." ”

The old professors are all noble, Qin Feng nodded: "Okay, then the five thousand yuan a month, we will put it into a special account, which can be used as the university's project research and development fund, and if college students want to engage in invention and creation, they can apply for funds." It's called the Pacific Fund, how about it? ”

So, under Qin Feng's arbitrary arrangement, the Pacific Fund appeared, which was to improve the scientific research level of the East, and to realize the development of science and technology by subsidizing college students to engage in scientific research, and a large number of scientific research achievements emerged in the past few years.

"Mr. Qin, I need to report to the school leaders for this cooperation." Professor Hu is cautious: "After all, I am still a teacher at the school, and if the school does not agree, then I can only continue to stay in the school." ”

"The school will agree." Qin Feng is very sure: "This is a win-win cooperation, and it is for the development of science and technology in our country." Dear students, regardless of whether the school agrees to cooperate or not, you can rest assured that our Pacific Group aircraft company will be registered within this week, and you can come to work in the company. By the way, what we need to study at the moment is an algorithm, and we need to use a computer, so I will first allocate you with a batch of 386 computers. ”

"Long live Mr. Qin!" The college students cheered instantly, and even Professor Hu was envious, it is good to be rich! In universities, any project has to be approved and go through the process, because the country wants to develop the economy, many projects cannot be developed.

If the university does not agree to cooperate, should I resign and go to Mr. Qin's company? This kind of quadcopter is really attractive! Professor Hu's eyes looked at the blackboard again, and the rough-looking introduction picture was the starting point of the entire Oriental Quadcopter UAV!

"Liu Yang, Hu Miaomiao, are you free today? If you have time, go with me, I will take you to the group headquarters to see, in the future, you need to approve funds, purchase equipment and the like, you need to go to the headquarters, I will take you to familiarize yourself with the familiarity, by the way to buy a computer to arrange down. ”

"Free."

"Dad, I'm going."

Professor Hu looked at the direction Hu Miaomiao left with mixed feelings. He thought for a moment: "That's the end of today's work, you all disperse, I'll go to the office building." ”

Liu Yang and Hu Miaomiao walked outside, watched Qin Feng open the door of Santana, and sighed even more that in Capital University of Aeronautics and Astronautics, only the president can sit on Santana! This Mr. Qin is the same age as them, but he is already a successful person in society.

"Get in the car!"

"Well, Mr. Qin, where is the headquarters of our group?"

"Chocolate Mansion."

"Chocolate Mansion? I've heard that the rent over there is very expensive. ”

"Well, it's very expensive, but for our group, it's a drizzle." Qin Feng said: "You don't have to worry about money, how much is needed, how much our group allots, but we must have core technology, we are now focusing on software and algorithms, and in the future, we have the strength, we have to engage in the corresponding chips." ”

Chip! Hearing this, Liu Yang and Hu Miaomiao were stunned: "Mr. Qin, do we still want to engage in hardware?" This is the weakness of our country, and the Institute of Computing of the Chinese Academy of Sciences has given up. ”

"They gave up, here we come!" Qin Feng said: "The control of this quadcopter drone is very complicated, it needs advanced chips, if we use foreign chips, it will always be stuck by others, we have to develop our own chips, when the time comes, even if someone wants to imitate our products, they can't imitate it!" ”

Every time the Pacific Group invents a new product, there will be a large group of people who want to imitate it, which is the most intuitive in the field of motorcycles, and a group of manufacturers follow their butts, and after copycats, they pull down the price and destroy the whole market.

In the field of unmanned aerial vehicles, it is conceivable that this will also be the case, and when the Pacific Group launches advanced unmanned aerial vehicles, there will be other manufacturers who want to imitate them, and they will invest hundreds of millions or even billions of dollars, and finally be beaten by hundreds of copycats?

Of course not!

There must be independent chips, for those copycat factories, independent chips are a black box, they don't know what is inside, and of course they can't imitate it.

Moreover, this can also avoid being stuck by others in the future, and you will cut off the supply at every turn.

Now the Pacific Group can't take care of so much, it can only find a few directions to engage in research and development, and continue to develop and grow in the future, the chip project will definitely be launched, and it is not too late to catch up from the nineties.

"Mr. Qin, if you want to engage in chips, I can introduce my aunt to you, she used to be involved in chips at the Institute of Computing of the Chinese Academy of Sciences." Liu Yang spoke.

"What's your aunt's name?"

"Huang Yi."

Crunch! Qin Feng stepped on the brakes: "It's better to pick up the sun than to hit the sun, let's go now!" ”
