Magi Craft Meister

The next morning I spent the night on Onogoro Island.

"Father, what are your plans for today?

Reiko asked Jin, who had rinsed his mouth and washed his face.

"Hmm, that's right... I'm going to build a small machine with the promised Magic Eye, and then I'm going back to Penglai when I see the finals."

"Okay."

Before that, Jen intended to have Rubina and Shu's airframes seen up close.

But first, breakfast.

This morning's offering is Japanese-style.

Porridge, plum dried, kombu tenancy, deep-fried and green onion miso soup, melon fillet, new incense.

Yeah, this plum dried is delicious.

Supa De Shu

"Tenancy tastes good."

It's well simmered.

Breakfast was for Jin, Reiko, and Marika.However, I didn't eat Reiko, so I was asking for a replacement or pouring tea.

Oh, it was delicious.

It was delicious.

Jin and Malika are satisfied with their brown rice tea.

"We'll go see Rubina and Shu's planes in a little while."

"Yes"

Both planes must be in the hangar of the airfield where the finals took place.

The second finals start at 9am.It is 7: 30 in the morning.I don't have much time.

"Jin-san, Marika, thank you for waiting."

Trihart Randall, the caretaker, arrived there.

"Oh, I've been waiting.Let's go. "

The movement is instantaneous because it is a "transfer gate".

Ah, Jin-sama, Marika sama

"Welcome!"

Rubina and Shu greeted me at the airport transfer gate.

"Now, look!And point out more and more bad things!I can't today, but I'll fix it by next time!!

"Rubina's always positive."

"That's what I do."

"Ha ha!"

Go to the hangar with that conversation.It seems that this area also serves as a light maintenance dock.

"Ooh."

Inside, Jin is impressed.

There were two planes in the middle.

The total length is about eight meters.Quite compact.

A pilot golem stood beside him.This one is as tall as an elementary school student and small.

"What is this regulation?

"The total length is 7 meters or more and the width is 8 meters or less, and the total height is not specified.Magic jet propulsion engine (Magijet engine) drive.Up to two propulsion engines.The pilot was a golem... "

There are detailed regulations, but Jin hasn't asked yet.

Of the regulations, 7 meters or more were assumed to be air warfare.

"I see, it's a big disadvantage to fight in the air on top of that..."

The bigger the target, the easier it is to get shot.

"So, Jin-san, how about that?

"Hmm, that's right... Rubina's airframe is 85 points and Shu's 80 points."

"That's tough....."

"It's tough....."

"Ah, let me tell you, even if I made it myself, it doesn't score 100 points.Even Reiko's body is 95 points.... my daughter scored 120 out of 100. "

It is Jen's theory that progress and development will stop if the score is full.

And I want to be a challenger forever.That is the creed of Mercy.

"... I see.Eighty-five is a pretty good grade, then. "

"Well, why am I five points lower?"

"Yeah, I'm going to give you a quick explanation."

First of all, from Shu's "Thunderlight", Jin began to praise it.

I lost the point on the horizontal tail.

"What do you mean?

"From the front, it's at the same height as the main wing, right?

"Yes, I was thinking of reducing the air resistance a bit...."

"Because of that, the horizontal tail is not working.Poor exercise, isn't it?... of course, a little, but... "

Ah, yes.

"That's because the horizontal tail enters the air turbulence generated by the main wing."

From the rear end of the main wing, a turbulence of air called turbulence occurs and flows backwards.

Since the horizontal tail is in the disturbance, Jin commented that the horizontal tail... the elevator (elevator) is not working well.

"I see...."

"I feel like I told someone before in the model airplane competition... didn't I thoroughly..."

In addition, Jin explained that it is better to conduct wind tunnel experiments using models at these times.

A wind tunnel experiment is an experiment that artificially creates a flow of wind, keeps it as if the aircraft were flying, and investigates the occurrence of air resistance.

It is not limited to aircraft, but is also used in vehicle body design.

"A wind tunnel experiment... I see"

"Trihalt, can you make it somewhere?

Jin talked to Trihalt, the caregiver.

"Yes, Jin-sama.I think it is possible.I'll arrange it later. "

"Please, I'll send the details to Testa."

"Thank you."

Wind tunnel experiments have also been conducted in Penglai.With that data, we can quickly create an experimental wind tunnel on Onogoro Island.

"Another point to reduce is that the upper and lower corners are too large."

I knew it.

Since the retraction blade itself has an upper and reverse angle effect, it is too strong for stability when applied at the same upper and reverse angles as the straight blade.

For this reason, Jen saw that it was causing the mobility to decline.

"I'm no better than an amateur in aerodynamics."

In fact, Jen built an aircraft with engine power that could be said to be excessive, and there was no point in forcing it to fly...

"I think we should fix that."

"Okay."

"Jin-san, what's mine?

Ah, next is Rubina's Nile IV.

Yes!

"The overall design is good.That's right. "

"Thank you!

Jen himself is not good at designing, so he appreciates Rubina in that regard.

"However, the actual Delta wing machine is slow and the lift is small, right?

Ah, yes.

If origami planes are large, the air density will sufficiently support the plane, but this is not the case when it comes to the actual plane.

At takeoff and landing, a large pick-up angle (angle of the main wing with respect to the direction of flight) is required.

"I was a model when I came out of the tournament, so I was able to get enough lift even with the size of" Nile ", but that wasn't the case when it came to the actual machine, was it?

"Yeah... yes..."

"I was a Golem pilot around here, so I landed dangerously."

Jin said that if you were a human, you would probably fail to land about three out of ten times.

That's the point.

"I see....But I don't know what to do... "

"It's also a wind tunnel experiment, where the same delta wing changes the angle of the leading edge, changes the cross-sectional shape, and so on."

"Ok!

I was talking to both of them, and I wanted to participate more and more.

Later, as promised, Ren used Reiko and Malika as assistants so that they could relay the fighting from the air, and he created three small airships with "Magic Eyes" attached to them.
