Episode 990: The Clear-Eyed Madman (15)

“So this is how this scheme came about?”

Da Vinci answered the question about fragrance by bowing his head.

“That’s right.”

“Hmm…”

Hyang, who was looking at the sketch again while listening to Da Vinci’s answer, pointed out the problem to Da Vinci.

“It seems like I’m turning this pinwheel to rise and fall, is that correct?”

“That’s right.”

“Then how are we going to move?”

“Isn’t this a flying machine? What’s the difference between a flying machine and a bhikkhu? A flying machine only needs to float and land, but doesn’t a flying machine work properly only when it flies in the direction you want? If it just floats and lands like this, doesn’t it seem worse than a self-flying bhikkhu?”

“Ah…”

“I will allow you to devise it. However, if this part is not resolved, it will only become a plaything for wealthy people. In that case, no matter how much I do, I cannot ask the emperor for permission to produce it.”

“Yes, I will keep that in mind.”

After receiving permission from Hyang, which was not permission, Da Vinci took the sketch with a stern expression and left Hyang’s office. Hyang, who was watching Da Vinci disappearing through the window, muttered with an excited expression on his face.

“Now, I wonder what solution Da Vinci will come up with. But is it possible with a steam engine?”

In the case of self-powered flight, this was possible because of the enormous size of the air sac. However, the steam engine’s thrust-to-weight ratio was a problem. Because the power output was low compared to its size, the flight speed of the self-powered airplane was not very fast. Thanks to its advantage of being able to move in the desired direction high in the sky, it was only used by the military for reconnaissance or communication.

Self-flying monks were something that could never be used for transportation and could not be used for tourism, as they were crowded out by monks. Therefore, Hyang thought negatively about the adoption of steam engines as the power engine for flying machines.

“If that were possible, I would have made it first…”

Even before the intervention of fragrance, England’s George Cayley had envisioned an ‘Aerial Carriage’ powered by a steam engine. It was a helicopter with four disc-shaped rotors and two propulsion propellers, but it ended up being a model.

In addition, there were continued attempts to use steam engines as power plants for airplanes, but they ended in failure. Eventually, the Wright brothers, who used an internal combustion engine, succeeded in flight, which led to a dramatic development in airplanes.

* * *

“….. That’s why I received the order, ‘Allow the design, but not the production.’”

“I see. There was that part.”

At Da Vinci’s explanation, Gong Yazhang nodded with a face full of disappointment.

“Then what should we do now/”

“We also have to figure out how to move. And actually make it fly.”

“Isn’t the production prohibited?”

“To be precise, you said that you would not ask His Majesty for permission to produce it.”

Gong Yajang expressed doubts about Da Vinci’s words.

“That’s what you said. is not it?’

“It’s completely different!”

“Huh?”

“Think about it! Why are we asking for production permission? Isn’t it a budget issue?”

“That’s right.”

“I have a lot of money!”

“Aha!”

Hearing Da Vinci’s words, Master Gong slapped his forehead. Among the craftsmen currently working in Area 51, the richest was Da Vinci. No, only Area 51. Rather, the person who was treated as a very wealthy person even outside was Da Vinci. Da Vinci said in a powerful voice,

“You can’t find the answer just by scribbling it down on paper! If that were possible, he would be a genius who would go down in history! Then there is one way! Even if it’s just a model, all you have to do is actually make it and check for problems!”

“So you’re going to make a model with your own money?”

“That’s right! So, will you join us?’

“of course!’

In this way, Da Vinci and Gong Yajang joined hands and jumped into helicopter production.

* * *

Da Vinci and Gong Yajang gathered in Da Vinci’s workshop as soon as they finished their daily work and put their heads together.

“To move in the desired direction, you have to push or pull. They say it does, but the conclusion is that it needs to be equipped with a propeller.”

“A pinwheel-type propeller would be better.”

“Should I put it on the front or the back?”

“Wouldn’t it be easier to control it if it were mounted on the back?”

The two people talked a lot and sketched Da Vinci. Additions and subtractions were repeated. By redrawing the tattered sketch over and over again, da Vinci’s helicopter gradually took shape.

“The problem is the propulsion engine, and the engine that turns the wind vane on the rise and fall side and the wind vane for propulsion are Should we attach a separate moving mechanism?”

Gong Yazhang shook his head at Da Vinci’s suggestion.

“Then it would become too heavy. Space is also an issue. “The engine must only go one way.”

“Then we should install a distributor.”

“That’s right.”

The ‘power distributor’ was not an unfamiliar concept to the craftsmen of the empire at this time. It had already been applied to various machines used in the empire’s textile workshops. It was because they were using it.

“Hmm… I think it would be too weak to use as a blood rope.”

“Then how about using a chain?”

“That would be fine.”

Two months passed in this way and the two met for the first time. I was able to complete the first blueprint.

“Now, let’s listen to the model!”

“That’s good! My hands were itching already!”

After looking at the blueprint they completed, the two people were satisfied and started making a model right away. After completing the model with a mainspring instead of a steam engine, the two people immediately started experimenting.

“First of all, make sure it comes up properly . Let’s check it first.”

“Okay.”

The first experiment they attempted with excitement failed spectacularly. The model they created only floated and sat down repeatedly and failed to rise properly. What was even worse was that the fuselage attached to the bottom of the pinwheel, which was responsible for rising upward, It was true that the pinwheel rotated in the opposite direction, and at a fairly fast speed.

“Why on earth?”

“Why!”

When a completely unexpected phenomenon occurred, the two were unable to find the cause and were racking their brains. As I was pondering over and over again, Field Manager Gong opened his mouth.

“In the past, when I was making a model of an electric wire that runs on a steam engine, there was something similar to this. At that time, Tae Sang-tae gave an answer and it was to make two pinwheels and make them turn in opposite directions. “How about applying it?”

“huh?’

Da Vinci, who did not properly understand Gong Yajang’s words, raised a problem:

“Then wouldn’t it just spin around in place?”

“So, the direction of the pinwheel’s wings is reversed. If this side turns to the right, it goes forward, and the other side turns to the left, and it goes forward.”

“Hoo…”

Da Vinci, who was nodding his head and making a comment to Gong Yajang’s explanation as he continued to make more hand gestures, got up from his seat. I unfolded the paper.

“If I do well, I think I’ll be able to do it, right?”

Thus began the second attempt.

* * *

The second attempt was half successful and half failure. First of all, we were able to catch the fuselage spinning. However, it still couldn’t rise properly and was shaking in place.

“I think this part is due to the lack of power in the mainspring.”

“I guess so. Hmm…”

Da Vinci’s expression was not good at all even though he nodded.

“Any problem?’

In response to Gong Yajang’s question, Da Vinci pointed to the pinwheels sticking out on the left and right sides of the model.

“I don’t like it.”

“You don’t like it?’

“It doesn’t fit the name.”

In response to Da Vinci’s answer, Gong Yazhang placed his hand on his forehead.

“Then what are you going to do? Other than that method, is there any other way to stop the fuselage from going crazy?”

“That’s true. Still, it’s not pretty. Hmm…”

The ball manager, who was stroking his chin and doing some calculations, looked at Da Vinci.

“Maybe it’s possible?”

This is how the third challenge began. Finally, on the third challenge, the two smiled brightly.

“We’ve finally overcome the crisis!”

“Hahahaha!”

The two people, laughing out loud and tapping each other’s shoulders, shouted confidently.

“Okay then. Let’s move on!”

The second hurdle was the problem of movement.

“I think the design is right…”

“Isn’t it?”

The two people stroked their chins as they looked at the properly refined and completed blueprint. The two people created it. The helicopter had a particularly special appearance, as it was a reflection of the experience accumulated from previous attempts.

First of all, the helicopter had a total of four wind vanes. To be more precise, it was equipped with two coaxial inverting rotors. It floated and lowered vertically. One is in charge of the front and the other is in charge of propulsion from behind. The two suffered from the inversion phenomenon of the rotor and fuselage, so they adopted a coaxial inversion rotor for the propulsion pinwheel.

“It certainly seems like the design was right, but was it really made properly? “You can only find out by actually making it.”

“That’s right. Because it’s impossible to control it with a model.”

– Whether real movement is possible can only be known when a person gets on board and operates it.

“Hmm…”

The two, who were pondering to find a solution, soon came up with a similar answer. .

“I should go to Taesang.”

“As expected, to Taesang…”

Seeing that the two had reached a consensus, they immediately headed to Sugang Palace with blueprints and models.

* * *

Da Vinci and Gong Ya-jang, who came to visit them, When Hyang saw the blueprint and model, an expletive came out without realizing it.

“You crazy!”

‘Why is this coming out here!’

The model submitted by Da Vinci and Field Marshal Gong resembled a helicopter made by the Russian Kamov company, and the helicopter drawn in the blueprint submitted that they actually wanted to make was the Defiant- It resembled. To be more precise, it resembled what would appear if all the shells of Defiant-X were removed.

‘So how on earth should I replace it to get a result like this!’

While Hyang, mesmerized by the unimaginable blueprint, was screaming inwardly, Da Vinci and Gong Yazang were looking at the floor with pale faces. This

was because of the swear words that Hyang had uttered.

‘You’re dead!’

‘How should I pray… Should I ask for their life unconditionally…’

While the two were fretting, Hyang looked at the blueprint once again.

‘After looking at it again, I see that there is a limit.’

There were clear limitations to the blueprints and models submitted by Da Vinci and Yajang. The limitations of the power engine were expected from the beginning, and the helicopter they designed had another limitation. – It is

possible to lift, lower and move, but fine adjustment is not possible. .

‘If that was possible, it would have already been released even after computers came out.’

“Hmm…”

After reviewing the blueprint several times, Hyang came to a conclusion.

“You two can raise your heads.”

When Da Vinci and Gong Yajang, who were just looking at the floor, looked up, Hyang grinned and continued speaking. .

“Is it just the two of us who can enjoy this fun game? I feel sorry for you. “I guess I’m kind of talented too.”
