Magi Craft Meister

"Hmm, how about using the tip tail in this format?

Jen spoke up.

"What do you mean, Master Jin?

Rubina asks.

"Yeah, when I fly in the sky, behind my wings, I say 'turbulence', and the air disturbance grows big and small and occurs. That's why the plane is mounted slightly off the main wing and tail."

"Oh, yeah."

"If you do, the turbulence that could be behind the tip tail will affect the main wing, right?

Rhodotos guessed what Jen wanted to say.

"That's right. That's why tailless aircraft have a lot of advantages."

Jen did not properly complete aeronautical engineering, aerodynamics, or hydrodynamics. I just purchased fragmented knowledge in the modeling process.

But on the other hand, the knowledge is quite practical.

Nevertheless, it is for the 'model', so there was an ambiguity as to how far it would work for the actual machine.

"Then, this way"

Jen takes another piece of paper and folds it quickly.

What's next, standard? is a triangular paper plane.

Incidentally, hang gliders also have shapes that are close to this.

"Delta wings, but this shape is also suitable for speeding."

On the other hand, it is also suitable to fly as a paper plane. I mean, the response speed range must be wide, Jen said.

Since the wing area can be taken large, the wing surface weighting (fuselage weight per unit wing area) can be reduced, thus ensuring stability at low speeds.

"I want to go with this."

Rubina was the first to agree.

"Yeah, wouldn't that be nice?"

Rhodotos also agreed.

"All right, then let's study it on this line"

Jen speaks the conclusion.

In a rambling way, I can handle some impossibility because it's a world with magic.

but it is still definitely more efficient to design in line with the laws of physics.

"So, this is research?

"Experimenting with models is important."

Jens had experimented with making origami planes in various shapes and observing them when flying.

"I'm not giving you supersonic speed, so the angle doesn't have to be so steep."

Jen wants to make the retraction angle about 60 degrees and try to triangle it as a planar shape.

"Right. It seems to be well balanced as a shape."

"Wouldn't it be a little longer on the side, like, 45 degrees?"

"In that case... is it a right angle triangle from the top? Still not bad."

Those were Jens who would repeat those exchanges.

Even in Penglai, Reinhardt was on this stream.

He wasn't very interested in the vehicle system, but the "1st Malika Cup" seems to have blood rolling.

"I think I'll build my own fuselage, too.... Leela, help me"

"Yes, Master Reinhardt"

Leela, is an automatic doll made by Reinhardt with vine hair (Automata).

Usually as an assistant, he became a 'black knight' by wrapping his armor around him.

Nevertheless, besides commissioning, I've never revealed myself as a 'black knight'. Because I didn't have to.

Reinhardt, at my pace, relaxed and built the fuselage.

In the end, Jens' prototype became a delta wing with a retreat angle of 45 degrees.

From the top, it's a right angle two-sided triangle, but it looks like a sloppy chess comma or an undersized home base because it cuts off the tip of the wing and has an auxiliary wing perpendicular to it.

"This is how stable the model was."

"Right."

Even when it came to the model, it was made by processing light silver, starting with a size of about 30 cm long, but by the time of the final experiment it was two meters long and nearly half the size of the actual machine.

I asked Reiko to throw this and see how the skies were doing.

"Yeah, let's build three planes with the same basic configuration."

Jen said.

"Oh, so you just do the final adjustments on your own?

"That sounds interesting"

Rubina and Rhodotos also agreed.

Design first, though.

There is no formula to give the required figures, so there are many parts to be decided by the rules of thumb.

The wing area will be combined with the assumed fuselage weight (including passengers), but this is not a problem as there is a wealth of precedent data.

As for strength, this was not as problematic either, as 64 light silver can be used for structural materials to facilitate reinforcement.

Though, Jen checks, so the strength of the vegetables was enough.

"Then the pilot."

Because of the no-tail range, the main wing has Elevon (Elevator + Elron), while the vertical tail has Ladder.

"Think about low speeds and put a thruster on it"

"You will be."

These shall be able to be operated from the cockpit using wires.

"Have you decided how much propulsion and blowing engine (blow engine) to use?

Rhodotos asked Jen.

"Of course. We'll design this place sparingly."

Jen intends to make his own design and production.

"Then around the cockpit."

Rubina insisted that she also wanted to think of the habitability somewhat, and neither Jen nor Rhodotos differed from it.

"I'll be riding for some time."

Jen also wants to contain vibrations and shocks on landing.

Such structures are already conceived together, and all that is left is enough to try and make and adjust.

The prototype was completed the next day.

The test flight by Reiko was also a success without any problems.

"You did it."

"I did it."

"You did it"

The first aircraft thus created will be 'preserved' due to the mere wishes of Rubina and Rhodotos.

Because 'it's the supreme dish we've created ourselves, so we want to keep it as a memorial for good as it can be done'.

Once made, it stays as a 'design base (template)', so less than a tenth of the time it takes to make the same object. The more mass-produced it is, the more effective it will be.

This time, three planes are to be made of the same object, adjusted with each, and compared.

That's what I'm looking forward to as Jen.

"Reinhardt's making something, too."

The jet lag between "Onogoro Island" and "Penglai Island" is just half a day, so when we're asleep to suit each day and night, we don't know much about each other's situation, but there it is, "Old Master".

Through you, Jen and Reinhardt had an easy but grasp of each other's situation.

"If you want to compete, you can do it with Hale."

to Jen's words that

"Nice."

"Fine, that!

and both Rubina and Rhodotos agreed.
