Magicraft Meister Part 3

"Hmmm, what about using the tip-tail wing in this format?"

Jin shouted.

"What do you mean, Jin-sama?"

Rubina asked.

"Well, when you fly in the sky, there will be a lot of air turbulence behind the wings, called . That's why airplanes have the wings and tail fins mounted slightly offset from each other.

"Oh, I see."

"So you're saying that the turbulence created behind the tail wing would affect the main wing?"

Rhodes understood what Jin meant.

"That's right. That's why tail-less planes have their advantages."

Jin did not have a thorough training in aeronautical engineering, aerodynamics, or fluid mechanics. He has only acquired fragmentary knowledge in the process of building models.

On the other hand, his knowledge is quite practical.

However, since it is for <, I was not sure how much it would be applicable to the actual machine.

"Then, this is the way to go.

Jin picked up another sheet of paper and folded it quickly.

This time, it was a standard triangular paper plane.　This one is a standard triangular paper airplane.

Incidentally, there is a hang glider with a similar shape.

"It's called a delta wing, and this shape is also good for speed," he says.

On the other hand, it is also suitable for flying as a paper airplane. In other words, it has a wide speed range," Jin said.

Since the wing area can be made large, the wing loading (weight per unit wing area) can be reduced, and stability at low speeds can be ensured.

"I'd like to go with this."

Rubina was the first to agree.

"Yes, I think it's a good idea.

Rhodes agreed.

"Okay, let's work on this.

Jin spoke his conclusion.

In a rough way, the world has magic, so it is possible to make some difficulties.

However, it is certain that designing in accordance with the laws of physics will be more efficient.

The design of the system is the same as the design of the system in the past.

"So, this is your research?

"It is important to experiment with models.

Jin and his colleagues made origami airplanes of various shapes, flew them, observed them, and ...... experimented with them.

"We're not going supersonic, so the angle doesn't have to be very steep."

The angle of recession should be about 60 degrees, and Jin wants to make an equilateral triangle as a plane shape.

"Yes, that's right. It seems to be well-balanced as a shape.

"Maybe it could be a little longer horizontally.　About 45 degrees."

"In that case, it would be a right-angled triangle when viewed from ...... above. That's not so bad.

Jin and his team repeated this kind of exchange.

In Horai Island, Reinhardt was also following this trend.

He has never been interested in vehicles, but the <<1st Marikka Cup>> seems to have set his blood boiling.

I think I'm going to try to build one for myself. ...... Leela, help me."

"Yes, Mr. Reinhardt."

Leela is an automaton with wisteria-colored hair, created by Reinhardt.

Normally, she acts as an assistant, but when she puts on her armor, she becomes a .

Though he has never shown himself as a except for test runs. There was no need.

Reinhardt took his own pace and built the aircraft at his own leisure.

In the end, Jin and his team's prototype was built.

In the end, Jin and his team's prototype became a delta-wing aircraft with a 45-degree recession angle.

From above, it looks like a right-angled isosceles triangle, but with the wingtips cut off and an auxiliary wing attached vertically, it looks like a chunky chess board or a home base that is a little too short.

"This is how stable the model was, wasn't it?"

"Yes, that's right."

The model was made of fabricated light silver, and although it started out about 30 centimeters long, by the time of the final experiment, it was 2 meters long, almost half the size of the actual model.

Reiko threw it to the ground to see how it glided.

"Well, let's make three units with the same basic configuration.

Jin said.

"Oh, and only the final adjustments will be made by each of us?

"That sounds interesting."

Rubina and Rhodes agreed.

The first step, however, is design.

There is no formula for determining the required values, so there are many rules of thumb to be followed.

The wing area is to be determined based on the assumed weight of the aircraft (including passengers), but this is not a problem since there is a wealth of precedent data.

Strength was not much of a problem, since the use of 64LBE for structural materials facilitates strengthening.

However, the bare strength was sufficient, as Jin checked it.

"And then there's the control system.

Since it is a tailless aircraft, it has elevons on the wings and a rudder on the vertical tail.

"We should also add thrusters for low-speed flight.

"Yes, that's right."

These will be operated from the cockpit using wires.

"Have you decided on the size of the propulsion system and the blow engine?

Rhodes asked Jin.

"Of course. We'll make a generous design here.

Rhodes said, "I will design and build it myself.

"Then, the cockpit area will be the next step.

Rubina insisted that some consideration be given to comfortability, and neither Jin nor Rhodes had any objections to this.

"We're going to spend a certain amount of time in the cockpit."

Jin also wants to minimize vibration and shock during landing.

Such a structure has already been conceived, and it is just a matter of making adjustments after the aircraft is built.

The prototype was completed the next day.

Reiko's test flight was a success.

We did it!

We did it.

We did it.

The first prototype was saved at the request of Rubina and Rhodes, because they had built it themselves.

Because it was the best thing they had ever made, they wanted to keep it as it was for a long time as a souvenir.

Once the product is made, it remains as a <, so the time and effort required to make the same product is less than one-tenth of the original. The more mass production is done, the more effective it becomes.

This time, we are going to make three identical machines, adjust each of them, and compare them with each other.

That is something that Jin is looking forward to.

"Reinhardt is building something, too.

< and is just half a day, so they are sleeping and waking according to their respective days and nights, so they don't know each other's situation very well, but that is where <> comes in.

Through the old man, Jin and Reinhard knew each other's situation, albeit briefly.

Jin said, "If we are going to compete, it would be nice to do it in Hale.

Jin said,

"That's good."

"That's a good idea!

Rubina and Rhodes agreed.
