Top of the big era

A helicopter is not an airplane.

One is rigid body dynamics and the other is fluid dynamics.

These two types of aircraft, in the field of unmanned aerial vehicles, have a proper term respectively, the former is called the rotor UAV, and the latter is called the fixed-wing UAV.

Rotary wing drones are easier to operate. The operation of fixed-wing UAVs is too complicated, and ordinary people can't understand it at all. Generally, they can only be seen in aircraft model exhibitions.

However, from the perspective of manufacturing technology and flight technology, it is of course more difficult for rotor drones.

The earliest human aircraft, except for hot air balloons, were fixed-wing taxiing aircraft.

Therefore, most of the aircraft model exhibitions held by Beihang are fixed-wing aircraft.

Both AVIC I and AVIC II are in-depth partners of Beihang University. Many academicians and professors in the school will provide technical support to the two state-owned enterprises, and even hold important positions.

As the opening debut, of course you have to show off your skills.

Let's try the unmanned helicopter, which is still a technical blank in the domestic drone market!

"Buzz!"

The propeller spins highly and is very loud.

The roar of the humming engine can be heard tens of meters away.

Then, under the cheers of thousands of Beihang students, the helicopter slowly lifted into the sky, and the scene was just like the Jiuquan launch center.

The aircraft model exhibition held by Beihang University is regarded as the highest level of technology in China, and many students will participate in the competition with unmanned helicopters.

The difference is that this drone is huge!

Mr. Li Derui, who was invited from the Bayi performance team, sat on the rostrum and gave a cordial explanation: "This is a load-carrying drone developed by AVIC II. It is a new model independently developed. This aircraft The length is 3.25 meters, the height is 1.05 meters, the width is 0.6 meters, the diameter of the rotor is 3 meters, the highest flight altitude can reach 1000 meters, the total endurance time is 1 hour, the flight distance is 100 kilometers, and the maximum load can be 50 kilograms..."

Zhou Buqi was stunned by this explanation.

He called Ma Pingshan over and asked him in surprise, "Is this bragging?"

"Load capacity..." Ma Pingshan hesitated for a moment and shook his head, "It should be bragging, but the flight distance and battery life should not be a big problem, and there are no technical obstacles in this area."

Zhou Buqi frowned and said: "If it's aerial photography, it must be equipped with a camera, and the load must be sufficient."

Ma Pingshan glanced at him and lowered his voice, "Under the same conditions, the load capacity of the multi-rotor must be stronger than that of the single-rotor, and the technical difficulty is also lower."

"Are you graduating next year?"

"Um."

"There are still too many restrictions in the capital. If the drone business wants to have more room for development, it still has to go south, especially close to the Hong Kong government to facilitate technical exchanges with the outside world. It will definitely not work behind closed doors."

"To the south?"

Ma Pingshan was taken aback for a moment.

Zhou Buqi nodded and said: "For sure, when the time comes, individual businesses on the Xiaonei network will also be moved to Eastern Guangdong Province."

During this period, after full communication, it was agreed that Weimi.com's team should be located in the south.

First of all, Southside is more open and able to keep up with trends, catering to the appetite of young women in the new era, and in line with the positioning of Weimi.com;

Secondly, Eastern Guangdong Province is the production base of domestic cosmetics and clothing. This is a new profit point that Shi Jinglin is looking for for group buying on Xiaonei. It is convenient for contact with suppliers and supply;

Thirdly, the person Shi Jinglin is looking for for Weimi.com is Zhao Ying, who is the editor-in-chief of the fashion channel of "Southern Metropolis Daily" and works in Pengcheng, where all her connections are.

Letting her come to the capital to work is tantamount to breaking her own arm.

And most importantly, Zhou Buqi has his own plan for the drone business.

Next year, DJI should appear, and the location happens to be Pengcheng.

Just relying on Zhao Ying's local media contacts and channel resources to help find that start-up company, and then merge with Ma Pingshan's team.

Zhou Buqi doesn't believe in coincidences.

When so many coincidences occur, the only explanation is fate. Destiny, let us walk together, how wonderful!

Ma Pingshan was in a dilemma: "I have graduated, but there are quite a few people in my team who haven't graduated yet. At least they won't be able to go south until the next year."

"The emerging market of drones still has to go to the south to find technology overseas..."

In the middle of Zhou Buqi's words, he stopped abruptly and was stunned.

Over the track and field, the unmanned helicopter performing a vertical flight suddenly lost control and wobbled. Even though the operator hurriedly changed direction and let it fly forward, trying to regain balance by inertia, the drone still flew lower and lower...

By the end, the whole body had tilted.

Around the track and field, there was a "buzz", and agitation began. There was noise and screams everywhere, and the surrounding students retreated one after another.

Next, a loud bang was heard.

The unmanned helicopter fell heavily to the ground!

Two propellers broke directly and jumped out.

Fortunately, the students all backed away and no one was hurt.

The occurrence of this scene caused an uproar in the audience!

This is the opening show?

That's it?

It's better to let the school's model airplane team play!

In the National Aerospace Model Championship in August this year, the Beihang Aeromodelling Team set a new national record in the radio remote control model load project group and won the championship!

Two of the core members are from Ma Pingshan's team.

Look at the venue again.

With the failure of the performance, the faces of the guests on the rostrum were not very good-looking, especially the leader of the second episode of AVIC, whose face was as dark as the bottom of a pot.

However, you have to deal with the aftermath!

After the drone fell, it did not fall apart, and the engine was still running!

The "buzzing" noise is like bursts of ridicule from the students.

Teacher Li Derui, who was in charge of the review, was well-informed and said calmly: "Turn off the engine first, turn off the engine."

At this time, the staff ran over from a distance and turned off the switch.

As a result, it may be an operation error, or it may be broken. The internal wires were directly short-circuited, and the flames ignited instantly, covering the whole machine in an instant.

"It's over now, it's completely scrapped."

Ma Pingshan shook his head in disappointment.

He thought he could take this opportunity to learn something, but it turned out to be a farce.

The staff took the fire extinguisher to the stage again, and at least it calmed down.

The host sorted out his emotions, and came to the stage with enthusiasm, saying that he wanted everyone to give the warmest applause and welcome the aircraft model team to the stage!

Ma Pingshan was not interested in the level of the aircraft model team, and he held his chin thoughtfully.

Zhou Buqi looked at him amusedly, "What are you thinking?"

"The level of the national team is not very good, this is our chance!"

"what chance?"

"Opportunity to make money!"

Zhou Buqi smiled, "Have you figured it out?"

Ma Pingshan lost the disappointed expression just now, and became excited, "Our unmanned helicopter has more advanced technology and more mature craftsmanship!"

Zhou Buqi asked, "Do you know what is the most important point for a company's CEO?"

"You said it was to make money."

"Yes, it is the ability to make money. Therefore, 80% of the CEOs of Fortune 500 companies have sales backgrounds, 15% have financial backgrounds, and only a small part have technical backgrounds. To lead a company, you must have Keen business sense."

Ma Pingshan understood, and quickly said: "Okay, I'll go get ready now!"

Zhou Buqi nodded and continued to watch the performance.

The level of the aircraft model team is still good, and there is also a small unmanned helicopter, the shape...is similar to that made by the Ma Pingshan team, and it is probably their outdated product.

Flying around in the air, there are no difficult flying skills, the victory is a smooth landing.

It drew cheers and applause from the college students.

Next, there is Beihang's aircraft model club. Their technical level is even worse. They basically belong to aircraft model enthusiasts, and they don't have too advanced technology.

For example, the aircraft of the model aircraft team are all placed on the runway, and then the remote control is controlled to let the aircraft taxi and take off. The planes of the model aircraft club are more like toys, requiring the operators to run at high speed and throw them out with the help of their own inertia... The error rate is also high, and seven or eight planes fell in a short time.

The students laughed and laughed, which was very interesting.

The guest commentators also made witty remarks from time to time.

The atmosphere of the aircraft model exhibition finally eased from the embarrassment at the beginning, ushering in the climax of this aircraft model exhibition.

The host came to the stage and said in the most excited and excited voice: "Next, all leaders, teachers, and students, please come and enjoy the experience of Ma Pingshan, the second brother of the unmanned aircraft system engineering of our school's flight school, and his team. Air model performances brought by the team. Since last year, Brother Ma Pingshan has led people to specialize in the hovering technology of unmanned helicopters, striving to break the technical gap in the field of domestic civilian drones, catch up with international trends, and reach the world's advanced level This project has received strong support from Xiaonei.com, and has successively invested millions of yuan in research and development, just for the advancement of science and technology in China's aerospace industry. Therefore, I call on everyone to dedicate to Xiaonei.com with the warmest applause, thank them Generosity! Xiaonei is next door, hope they can hear our thanks."

Then, there was time for applause.

It's a pity that the applause was sparse.

Some people are annoyed.

What shit host? After selling such a big pass, let us all applaud and play? Do you think it was the leader's speech?

The host is from the Propaganda Department of the Student Union, with a embarrassed look on his face.

Seeing that Ma Pingshan had already brought in two helicopters and placed them on the runway, he breathed a sigh of relief and said loudly: "Okay! Brother Ma Pingshan's team is ready. Now, please leaders, teachers, and students, enjoy today's most exciting model airplane performance together!"

On the runway, there are two unmanned helicopters, one painted red and one painted gold.

Except for the color, everything else is exactly the same.

The propellers start and take off at the same time.

The rotation speed is the same, the take-off height is the same, and even the dynamics of take-off... are exactly the same!

Teacher Li Derui from the Bayi Performance Team was stunned and opened his mouth wide.

It can't really be a model show, can it?

Just like a real performance team, the planes are arranged in an orderly manner in the air, rather than chaotic individual skills.

So far, that seems to be the case!

Both drones took off vertically to a height of 100 meters, maintaining the same distance as they did on the runway. Then, just like praying to Buddha, the two drones leaned forward at the same time, flying forward, still maintaining the same distance, and still in the same flying state.

After flying 20 meters forward, the drone on the inside slowed down, but the drone on the outside accelerated its flight speed. When the turn was completed and the two planes maintained a straight line again, the flight status returned to exactly the same.

The flight distance is still the same as before.

On the rostrum, all the leaders and teachers stood up with expressions of disbelief.

Li Derui shouted excitedly: "Good! Good! This is the most exciting performance of this air show!"
