France, Paris, Town Hall, Patent Office.

Chu Yuqiang, the shopkeeper of the Dashi Garment Company, took another Ming man, and under the guidance of the staff, directly met Hubert, the director of the French Property Office.

Hubert has met Chu Yuqiang many times, because Chu Yuqiang often comes to apply for design patents for Zhu Jingyuan.

Although Chu Yuqiang is an agent, the design belongs to His Royal Highness the Prince of the Ming Dynasty, and the patent office can't deal with it casually.

Although Zhu Jingyuan didn't specifically ask for it, Chu Yuqiang felt that he should apply.

You can do without it, but you can't do without, otherwise you may be powerless when you are deliberately disgusted.

Hearing that Chu Yuqiang was coming again, Hubert directly invited them to his office and said very enthusiastically:

"Shopkeeper Chu is here again, does His Royal Highness Prince Dashi have a new design? I've got to get a good look at ......."

Chu Yuqiang came to apply for a patent, which indirectly allowed the director of the patent office to have the fastest access to the new design and stand directly at the forefront of fashion, and Hubert himself enjoyed it.

Chu Yuqiang greeted with a smile, and then directly explained his intention:

"It's also a design by His Royal Highness Prince Daishi, but this time it's not a costume design, it's an important invention.

"These two Guan Zhengping shopkeepers are representatives of Daming Airlines.

"Daming Airlines is the local industry of Prince Dashi in Daming, specializing in flying machines.

"These two people came here today to apply for an invention patent for flying machines on behalf of His Royal Highness Prince Dashi.

"Please also ask Your Excellency the Director to make arrangements."

At this moment, Director Hubert's enthusiasm was significantly reduced, and he asked quite seriously in a positive manner:

"Flying machines? Chu shopkeeper...... And about the shopkeeper, are you going to apply for some design related to the flying machine, or is it a patent for the invention of the complete flying machine itself? ”

The popularity of flying machines has always existed, but there is a lack of interest in the matter from people in the patent office.

There is even some numbness and boredom.

At this time, patent applications basically follow the principle of first invention, so it is necessary to verify and examine the actual objects.

It's not just a matter of simply submitting explanatory documents, as in later generations.

It's because the popularity of airplanes is so great, there have been related research, and many people have come to apply for patents.

But most of it feels like nonsense.

If the specific details of the design patent is fine.

For example, the flight rudder designed by Zhu Jingyuan, wire traction control, etc.

It is only necessary to show the feasibility of the specific structure.

It can be held in your hand or displayed on a table without flying.

There is also no need to fly up "up to standard".

There is no need to set flight standards.

As for the patents of the flying machine itself, it is troublesome.

First of all, they have to determine the nature of the thing, and they have to standardize the evaluation criteria for this thing.

The default conditions for the basic sample are as follows:

It is denser than air and does not float naturally, excluding airships and balloons.

It does not rely on external auxiliary forces, does not require external forces to drag and control on the ground, and excludes kites.

Able to take off on their own on flat ground, be able to fly continuously in the air and climb altitude, excluding gliders.

And it can carry at least one person.

The details of these conditions are sometimes difficult to judge accurately.

How high does it take to fly? How long does it take to fly?

Being able to move on its own after taking off in the wind, is it considered self-taking?

After being dragged to take off, let go and move on your own, does it count as taking off on your own?

The reason why it is difficult to judge is because the performance of the early aircraft is too weak.

The main reason is that the airfoil design is not scientific, and the lift obtained naturally is insufficient.

Coupled with the lack of engine power, it is not possible to run fast enough to gain wind lift.

They usually rely on a certain amount of natural wind speed to fly.

When the first aircraft of the Latt brothers were shown, they all relied on the right wind speed to take off.

Many airplanes don't have wheels, because adding wheels also adds weight to the structure, which makes it even more difficult to fly.

They can only glide on rails or sleds on grass, which in turn limits their speed.

Overall, it was very difficult to get an airplane to fly without a sufficiently light and powerful engine.

It flies low and for a short time, and has the characteristics of a kite, often with the help of the wind.

Whether they fly on their own or not is often in an ambiguous state.

It's a hassle and a lot of trouble to review and judge these things.

Inventors usually prefer lenient standards, and patent offices usually tend to favor strict standards.

Many people swear that their planes are flying.

The people from the patent office went over and asked him to show it, and he said to wait for the right wind.

Either they flew up a few tens of centimeters and fell, or they simply couldn't get up.

The patent office was tossed too much, and the interest quickly fell, and even felt bored.

Guan Zhengping, who is known as the shopkeeper of Guan, is actually a person from Daming West Factory, a man who looks ordinary.

Now acting as a representative of Daming Airlines, he smiled and said with great certainty:

"It's a complete flying machine patent, and His Royal Highness Prince Daishi's plane can continue to hover and fly.

"It doesn't need external force, it doesn't need wind power, and it can fly at an altitude of more than ten meters for more than two hours.

"We brought the plane directly here and could take off directly from the square in front of the town hall."

Hubert, president of the French Patent Office, was stunned:

"Two hours? The two shopkeepers are really not joking? ”

Guan Zhengping said with a glance:

"The identity of the Prince of Great Food is not a joke about this kind of thing.

"The Ministry of Industry has issued a patent certificate, which is included in the documents we submitted.

"We brought the plane directly over, and it was ready to be displayed on site.

"I'm sure that after the plane circled over Paris for dozens of minutes, no one would question it."

Guan Zhengping said and directly took out the prepared documents.

Hubert reacted immediately, and immediately cheered up and carefully read the documents.

Then the question was quickly raised:

"The Ministry of Industry issued the patent more than a year ago?"

The question is obvious, why did Daming issue a patent a year ago, and only now come to us to apply for it?

Guan Zhengping responded as a matter of course:

"A year ago we were at war, and when all the negotiations were over, it was the end of last year.

"And Prince Dashi is a character who pursues perfection, and this year's time has just made the plane more mature.

"That's why we're able to guarantee that the demonstration will last two hours if it's done directly over Paris."

Hubert confirmed the other's surging confidence, and after a brief moment of stunned thought, he said:

"It's despicable and reckless, if His Royal Highness Prince Da Shi's plane can really fly, we in France are very honored to be able to issue a French patent certificate to Prince Da Shi, I will arrange personnel and ask the two of you to prepare to show ......"

Hubert immediately went to call someone, and with all the censors, came to the square in front of the town hall.

There are not many people in the square at this time, but there are people coming and going from time to time.

There was a truck parked underneath the building, fully unfolded inside the compartment with a covered object.

It should be an airplane.

Hubert called the police and cleared two hundred meters of space in the town hall square and the street in front of him.

Guan Zhengping only needs 100 meters is enough, but Hubert is worried about going out, so he directly expands the range.

Pedestrians around quickly knew that someone was going to put flying machines on public display in the city center.

Some of the rich and idle Parisian citizens stopped curiously on the side of the road, stretched their necks and waited to watch the excitement.

The planes brought by Guan Zhengping were parts shipped from Daming itself, mainly the engines brought by Daming.

Assembled on the outskirts of Paris, secretly tested on the outskirts, and then pulled directly to the town hall.

Although the aircraft was redesigned and re-purpose-made, the shape was the most original, if not more primitive.

If it were placed directly on the ground, modern people might not imagine that it was an airplane.

There are only a few aluminum alloy frames for the body, plus canvas for the wings and rudder surfaces, which are fixed and pulled with steel wires.

Zhu Jingyuan deliberately asked for this production.

With the exception of the basic ability to ensure continuous flight, all other functions have been reduced and simplified as much as possible.

This makes it easy to disassemble and assemble at any time, and it is also convenient for relevant personnel to carry and transport parts.

It also minimizes the possibility of useful information being discovered by outsiders.

The size of the fuselage was also reduced, the wingspan was reduced from more than ten meters to nine meters, and the weight was reduced to three hundred and sixty kilograms.

The maximum power of the engine was increased to 64 horsepower, which was mounted directly on the nose along with the propeller.

The transmission structure and a propeller were omitted.

There is a chair on the engine that allows people to sit and fly the plane.

The amount of fuel carried was increased as much as possible, not just for the purpose of completing the display, but also for another purpose.

On the upper and lower sides of the two wings, there is a seal script spray painting, which is the trademark of the big food clothing firm.

It will float over Paris for two hours.

Hubert, the head of the French Patent Office, with the examiners of the patent office, watched several of Guan Zhengping's subordinates unfold the plane, and the expressions on his faces were a little subtle.

Zhu Jingyuan's plane looked even cruder than the other planes that came to test.

It can be said to be crude to the extreme.

The proportion of wings is also smaller than that of most aircraft.

And it also has three wheels and a seat, which is an extra waste of weight.

As a rule of thumb, it shouldn't be able to fly.

But the people of Daming Airlines swore that they did not dare to question Daming's, especially the design of Prince Dashi.

So I could only wait patiently for the show.

Guan Zhengping's craftsmen quickly completed the commissioning, because they had already flown outside the city.

The pilot tester said hello and sat directly in a chair in the middle of the plane's wings, and the support staff started the engine.

In the sudden smoke, the plane began to glide on the ground.

When he saw this scene, Hubert was stunned for a moment, as if he had thought of something:

"Loaded wheels keep moving? Got a longer run? Is this the right direction? ”

Before his words fell, several staff members around him also realized the problem and thought they had found a certain direction.

"If you don't have wheels to slide, you can't take off and land on the normal ground, and the friction on the ground will definitely reduce the speed......

Then they didn't discuss a few words, and the plane in front of them was already floating.

From the start to the departure from the ground, the plane was most likely less than twenty meters, and did not even run out of the compound of the town hall.

What's more, after the plane flies, it climbs upwards very naturally.

It doesn't have the feeling of being shaky, heaving, and ready to fall at any moment as other testers used to be.

It is as if the aircraft is not being tested and demonstrated, but in a very natural way of everyday use.

Hubert and the surrounding staff all froze their expressions.

Everyone tilted their heads and watched as the plane took off and circled over the city hall.

Then he flew a figure 8 in the sky and began to fly down the street in front of the town hall.

When the plane was getting farther and smaller, Hubert reacted reluctantly and shouted:

"O my God! It's really flying! ”

The shouts around him also came and went.

"This is a real flying machine!"

"There is no doubt that no one will question it!"

"He's really flying, really flying like a bird!"

"The things that used to be foolish were all **!".

"Sure enough, Daming Technology is the first in the world!"

In front of the city hall, passers-by who were restricted to the surrounding area, and pedestrians on both sides of the street, also saw the planes flying overhead.

Just above the building on the side of the street, at a height of more than ten to twenty meters.

After a brief pause, these pedestrians also let out a series of exclamations and cheers.

"Flying machines!"

"It's really a flying machine!"

"They really flew!"

The shouting that started from the town hall seemed to form a wave, which spread along the street with the sound of airplanes.

Zhu Jingyuan's small plane is very slow in the plane, and the cruising speed is only more than 100 kilometers per hour.

However, compared to the carriages and cars on the ground, it is already beyond the speed of the limit.

And now there is no airspace control, and there are no other counterparts in the air, so you can fly as you want.

However, the pilot still remembered Chu Yuqiang's arrangement, flying on the bustling streets, flying on the streets of the aristocratic district.

The planes swept over the streets of Paris, allowing more and more Parisian citizens to see the planes in the sky.

Citizens who had not received the news at all before were shocked and dazed when they saw the plane.

But it doesn't stop them from cheering.

Human beings have finally taken flight on their own, and the joy of this event itself is something that all human beings can share.

As the planes continued to fly, the aristocratic tycoons of Paris began to see the planes and noticed the figures under the wings.

It was the picture on the button of their clothes, and it was said that it was actually the emblem of the Ming Empire, which made them quite proud.

Now seeing this badge flying into the sky, all the people who have similar emblems on their clothes also feel honored.

It seems that the operator and builder of an aircraft bearing such an insignia are his companions.

I have to say that Chu Yuqiang's publicity plan is very advanced, which directly raises the user's heart.

This is the same as many advertisements for brands that do not directly promote products, but only promote technology and taste.

It may not directly increase sales, but it can make users feel worthwhile.

Although I spent 200,000 yuan on clothes, I can't tell what is good except for the special design.

But this dress is high-end, and the style is different.

At the same time, the fifty-nine-year-old Duke of Orleans, saw the plane in the sky.

Then subconsciously asked his son Louis Philippe next to him:

"Is this a flying machine successful? That is the family's logo on it? Who financed this invention? ”

Thirty-three-year-old Philippe, the only king of the Orleans dynasty in French history.

I was also stunned when I looked at the emblem in the sky, and when I heard my father's question, I subconsciously raised my arm.

pinched the buttons of the cuffs of the slim suit, and showed it to his old father quite complacently:

"This is the emblem on the authentic Ming style formal attire, and it is said that this is the emblem of the imperial family of the Ming Empire......"

The Duke of Orleans was stunned:

"The emblem of the Ming royal family? Now the nobles of France have the emblem of the Ming Dynasty, and the sky of Paris also has the emblem of the Ming Dynasty, has France become a vassal state of the Ming Dynasty? ”

Philip's expression was immediately embarrassed, Dad, don't talk if you can't speak.

On the other hand, when the plane came to the sky above the French Academy of Sciences, it triggered a new round of cheers.

Lagrange, Laplace, and other researchers were alerted by their assistants to see planes flying in the sky.

"This is a flying machine, could it be that Daniel Bernoulli Jr. has succeeded?"

"According to his calculations, it would take more power to get his plane flying."

"So he managed to get the engine from Daming, and he should be able to succeed."

"Bernoulli's plane is different from this one, and this wing has the emblem of the Ming Dynasty!"

"The emblem of the Ming Dynasty? Is this the occupation of Paris by the forces of the Ming Dynasty! ”

"The war ended last year, and you haven't read the newspapers!"
