Helicopters are not airplanes.

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

These two types of aircraft have a proper name respectively in the field of drones. The former is called a rotary-wing drone, and the latter is called a fixed-wing drone.

The operation of rotary-wing drones is simpler. The operation of fixed-wing drones is too complicated for ordinary people to understand, and it can usually only be seen in model aircraft exhibitions.

However, from the perspective of manufacturing technology and flight technology, rotary-wing UAVs are of course more difficult.

The earliest human aircraft, apart from hot air balloons, were fixed-wing taxiing aircraft.

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

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

As the opening show, of course I have to show off my skills.

Let’s try unmanned helicopters, which are still technically blank in the domestic UAV market!

"Buzz buzz!"

The propeller rotates highly and makes a loud sound.

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

Then, the helicopter slowly took off under the cheers of thousands of Beihang students. The scene was just like the Jiuquan Launch Center.

The aircraft model exhibition held by Beihang University is considered to have the highest technical level in China, and many students will participate in the exhibition using unmanned helicopters.

The difference is that this drone is very large!

Teacher Li Derui, 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 that is fully independently developed. This aircraft

It is 3.25 meters long, 1.05 meters high, 0.6 meters wide, with a rotor diameter of 3 meters, a maximum flight altitude of 1,000 meters, a total flight time of 1 hour, a flight distance of 100 kilometers, and a maximum load of 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 and shook his head, "It should be a boast, but the flight distance and endurance should not be a big problem. 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 high."

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

"You'll graduate next year, right?"

"Um."

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

"Going to the south?"

Ma Pingshan was stunned for a moment.

Zhou Buqi nodded and said, "Definitely, by then certain businesses on the school network will also be moved to eastern Guangdong Province."

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

First of all, the south is more open, can keep up with trends, cater to the appetites of young women in the new era, and is 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 Shi Jinglin is looking for for school online group buying, which facilitates contact with suppliers and supply;

Third, the person in charge that Shi Jinglin was looking for for Weimi.com was called Zhao Ying. He was the editor-in-chief of the fashion channel of Southern Metropolis Daily. He worked in Pengcheng and had all his connections there.

For her to come to the capital to work would be like breaking her arm.

And the most important point is that Zhou Buqi has his own plans for the drone business.

By next year, DJI will appear, and the location happens to be Pengcheng.

Zhao Ying could just rely on Zhao Ying's local media connections and channel resources to help find the start-up company, and then merge it with Ma Pingshan's team.

Zhou Buqi doesn't believe in coincidences.

When so many coincidences occur, the only explanation is fate. Fate brings us together, how wonderful it is!

Ma Pingshan was in a dilemma: "I have graduated, but there are still several people in my team who have not graduated. They will have to wait until at least the year after next before they can go south."

"For emerging markets like drones, we still have to go south and look for technology overseas..."

Zhou Buqi stopped abruptly mid-sentence and froze.

Over the track and field, the unmanned helicopter performing a vertical flight suddenly lost control and swayed. Even though the operator hurriedly changed its direction and let it fly forward, trying to regain balance by relying on inertia, the drone continued to fly over.

Low, flying lower and lower...

Later, the entire body had tilted.

There was a "buzz" sound around the track and field, and it became agitated. Noises and screams spread, and the onlookers retreated one after another.

Next, a loud "bang" was heard.

The unmanned helicopter fell heavily to the ground!

Two propellers broke off and flew out.

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

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

Is this the opening show?

That's it?

Might as well let the school's model aircraft team take the field!

In the National Aerospace Model Championships in August this year, the Beihang Model Aircraft Team broke the national record in the radio-controlled model load-carrying category and won the championship!

Two of the core members are from the team at Ma Pingshan.

Look inside the venue again.

As the performance failed, 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 black 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 spinning!

The "buzzing" noise was like bursts of ridicule from classmates.

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 due to an operating error or it may have been broken. The internal wires were short-circuited, and the flames ignited and covered the entire machine in an instant.

"It's over now, completely scrapped."

Ma Pingshan shook his head with disappointment.

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

The staff came on stage again with fire extinguishers, and the situation was finally calmed down.

The host gathered his emotions and went on stage enthusiastically, saying that he wanted everyone to give the warmest applause to welcome the model aircraft team to the stage!

Ma Pingshan was not interested in the level of the aircraft model team. He pinched his chin, thoughtfully.

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

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

"What chance?"

“Opportunity to make money!”

Zhou Buqi smiled and said, "Do you understand?"

Ma Pingshan no longer looked disappointed 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 thing for the CEO of a company?"

"You said it was to make money."

"Yes, it is the ability to make money. Therefore, 80% of the CEOs of the world's top 500 companies are from sales, 15% are from finance, and only a small part are from technology. If you want to lead a company, you must have

Keen business sense.”

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

Zhou Buqi nodded and continued watching the show.

The level of the aircraft model team is quite good, and they also have a small unmanned helicopter, the shape of which is similar to the one made by the Ma Pingshan team. It is probably their discarded product.

Flying around in the air, there are no difficult flying skills, the better thing is to land smoothly.

It attracted cheers and cheers from the college students.

Next, there is the model aircraft club of Beihang University. Their technical level is even worse. They are basically model aircraft enthusiasts and do not have any advanced skills.

For example, the aircraft of the model aircraft team are placed on the runway, and then the remote control is controlled to make the aircraft taxi and take off. The aircraft of the model aircraft club are more like toys, requiring the operators to run at high speed and use their own inertia to throw them... Mistake

The rate was also high, and within a short time we had lost seven or eight planes.
To be continued...
