Chapter 26 Paste the Wings

Chapter 26 Paste the Wings
Zhu Jingyuan was extremely speechless. He came to the palace, but his main quest was not completed, but the side quest started.

The old emperor suddenly wanted to go to the consortium, most of which was based on his own advice and arranged the direction of the consortium's reform.

What Zhu Jingyuan could do was to follow his father and Zou Shangshu, say goodbye to Cao Junji and others, and leave the palace and take a carriage back to the Ministry of Industry.

No matter what the old emperor had in mind, he had to get the plane out first. Anyway, he also needed the patent for the plane.

So after arriving at the Ministry of Industry, Zhu Jingyuan asked Director Wang Lai for directions, and went directly to the office of Li Rui, who was in charge of aircraft design.

In a room the size of a classroom, there are eight desks facing each other on the walls on both sides. The layout looks like an ordinary middle school teacher's office.

Li Rui was lying on a large table drawing drawings, surrounded by several officials wearing the clothes of the Ministry of Works.

The officials noticed that Zhu Jingyuan came in. Although they didn't know Zhu Jingyuan's identity, they all recognized the robes of the emperor's grandson and bowed to say hello.

"Don't be too polite..."

Zhu Jingyuan hurriedly bowed his hands to return the salute, and at the same time explained his purpose, and walked quickly to Li Rui's side:
"I'm here to find Director Li. I'm the creator of the new wing and controller. Director Li, how is the progress now? Can I test it today?"

After hearing Zhu Jingyuan's voice, Li Rui glanced back slightly, got up to say hello, and explained:
"I report to Your Highness, I have completed the design drawing here immediately, but the modification of the test machine will also take time, mainly because the entire wing needs to be redone..."

Zhu Jingyuan immediately waved his hand and said:

"No need to redo, just put the skin on the underside of the wing."

Li Rui and the surrounding officials were stunned:
"Put it on?"

Zhu Jingyuan nodded directly and said:

"Yes, the key to obtaining lift is the relatively rounded bulge on the top of the wing and the relatively flat and smooth bottom, which is all it takes to have this shape.

"As for which shape of the bulge has the greatest lift, it's a matter of detail in the pursuit of the limit in the future.

"The wings of the aircraft you originally tested should all be like slices cut from the edge of a hollow barrel, right?

"Now put the open cut batter below, change it into a solid column shape and cut the slices to test.

"It's not too late to complete the test as soon as possible, first to make sure it can really fly, and then to slowly determine the optimal wing shape.

"With certain feasible goals, everyone will be more motivated."

Li Rui thought about it, and it was indeed the case:
"Okay, okay, let's try this first..."

Li Rui sat down and continued to draw the drawings, finishing the last remaining point.

Zhu Jingyuan was a little anxious, so he asked his father to borrow a car, preparing to take himself and Li Rui to the test site of the Ministry of Engineering with the drawings.

Zhu Jianyan hesitated again and again, and finally went with him.

There are many test sites in the Ministry of Industry, which are scattered in and around the capital city and in other places according to the danger, degree of confidentiality, and the type and scale of the required site.

The danger of flying machines is average, and the degree of confidentiality is not very high, but the required site is relatively large, and it was selected in the large outdoor test field in the west of the city.

Zhu Jianyan's driver drove and carried Zhu Jianyan, Zhu Jingyuan, and Li Rui to the test site.

Li Rui joined the person in charge of the test site and took Zhu Jingyuan and his son to the warehouse where the flying machine test equipment was stored to check the original test planes.

The earliest test aircraft, and the later mature aircraft, are very different in appearance.

From the era of World War I to modern times, the basic structure of most aircraft has a typical vertical fuselage, plus horizontal wings.

Coupled with the horizontal tail, vertical tail, and various forms of engines, the overall design tends to be unified.

However, the early test aircraft did not have a fixed shape at all, not to mention the three major directions of flapping wing, rotor wing and fixed wing.

Therefore, in this warehouse, there are large birds that are suspected to be able to flap their wings, a hanging basket with a giant bamboo dragonfly on its head, and a round frame with multi-layered wings in the middle.

However, the largest number are those supported by metal frames, with one, two or even three or four layers of flat wings superimposed.

In fact, this change has shown that their design has gradually moved in the right direction.

Those involved in the design and experiment should have discovered a certain rule that a purely deployed horizontal and vertical fixed wing is the simplest design that can provide lift.

But they haven't found the right answer, and they're still trying to figure out the right wing shape.

Those wings are mostly just wings, no serious fuselage.

A small number of them have a fuselage, and most of them have a bird-like head and fan-shaped tail, but the head and tail are immobile, and they look more like a giant kite.

Most of them have only two stacked wings, with an engine tied to the middle and two propellers tied to the front, but the size and wing structure are not exactly the same.

The two young craftsmen in their 20s who were in charge of the warehouse here followed Li Rui and looked at the things in the warehouse. One of them said enthusiastically:
"Mr. Li, what are you doing today, flapping or rotor?"

The craftsmen here also know that Li Rui does not really approve of fixed-wing aircraft, and relatively speaking, he is more supportive of rotorcraft and flapping-wing aircraft.

In fact, most people have this view. The flapper is compared to the flight of birds, and the gyrocopter can refer to the bamboo dragonfly, which is sure to be able to fly.

The fixed wing can only be gliding, in order to fly like a kite, it needs to be light enough to meet the wind strong enough.

As a result, today's Li Rui answered expressionlessly:

"Tested the fixed wing today, but it needs to be modified first. Then you can find two people to come over and prepare the materials according to my drawings."

The two craftsmen were a little surprised. How did Mr. Li measure the fixed wing?Can that thing really fly?

But they just work, and the master of the experiment says what to measure, so just prepare what is needed.

The two craftsmen left with the drawings, and Li Rui turned to Zhu Jingyuan and his son:

"Your Majesty, among the existing fixed-wing test machines here, there are five sets that are relatively reasonable and proper.

"The main difference is the wing size, the weight and power of the engines used.

"What standard do you think is more appropriate for the renovation?"

When Zhu Jingyuan heard this question, he suddenly had another curiosity:

"Mr. Li, what is the maximum power of the engine that can be installed on the shield car and the plane now?"

This question is actually a bit sensitive. If an ordinary person asks this kind of question, Li Rui will not be able to answer it, or he will not answer the correct data.

But Zhu Jingyuan is obviously not an ordinary person, especially when Li Rui thought of Zou Bingtai's arrangement, he directly explained the situation:
"The current maximum power of the engine mounted on the shield car should be around [-] horsepower.

"In fact, it can also be installed on the plane, but its weight is too heavy for the plane, which may cause the plane to not fly at all.

"In our actual test, the engine installed on the aircraft has a maximum power of [-] horsepower.

"Of course, the plane never flew in the end..."

Zhu Jingyuan blinked, and felt so pitiful when he heard it. His family car in his last life had nearly [-] horsepower, and this tank only had [-] horsepower.

But is the horsepower of this world the same unit as the original horsepower of yours?It seems really...

It was one of the power units in the "Daming Metric" unit system that was appointed by Emperor Shizu.

One horsepower is 75 kilogram force meters per second, which is the same as the original world metric horsepower.
