Magi Craft Meister

On the west side of the 'World Conference' building is the 'Academy', flanked by a research building.

One of them was "Aeronautical Research" and "Aircraft Laboratory".

"We're close to lunch, so we'll be in the lab right now"

Fione Fierce said.

The time is 11: 30 AM.

They say that if you don't line up quickly because the food is popular, the menu you're looking for will sell out.

"That's the factory, this is the lab"

The factory is a large building built of bungalows. The aircraft lab was built to lean in there.

Fione knocked on the door and was immediately opened from the inside. Looks like they've been contacted.

"I've been waiting for you," Magic Engineer "Magicraft Jazz," Sir Gin Nido!

"Hello"

There were about ten students in the lab and one elderly man who looked like an instructor.

"I'm Lower Eisker, Director of Aeronautics Research."

"I'm Zola Himmel, Deputy Director of Aeronautical Research."

"This is Ciel Ajour."

This is Ena Kouki.

"I'm Tyner Bito."

……

After each of them named themselves, they went straight into the chat.

When Jen reached the conference table at the corner of the lab as he was invited, there was a single drawing on top of it.

"This is..."

"This is the small aircraft we're considering right now."

said Lower Eisker, chief of department.

"... that's an interesting design"

That's what Jen had to say.

Anyway, what was depicted there was a double-leaf circular wing.

"I see, you did this to reduce the full length and width?

"That's Lord Jin, did you spot your intentions at a glance"

Lower Eisker impresses.

"This is going to make the left and right athletic better."

"Oh, you're right!

Fighters during World War I were mostly multileaf.

I thought Jen had read in some book that she was better at turning around because she could reduce the full width than a single leaf machine...

That is a one-sided way of capturing, and in fact, combined with the engine output, in order to secure the wing area for obtaining the required lifting force, and so on.

Engine output has risen, and during World War II, when the speed has improved, it has mostly become a metal single-leaf machine, and the speed has more than doubled.

I think you can see that large, long, and such shapes are difficult to rotate.

For this reason, "Aeronautical Research" came up with the idea of layering the circular wings in two steps and reducing the diameter.

"Normal circular wings seem to be about five to ten meters in diameter."

Deputy Chief Zola Himmel opened her mouth.

"So it affects the load, that is, the number of passengers. So, this' double-leaf machine 'assumes four people"

With four passengers, a single circular wing would have a class such as 6 to 7 meters.

Assuming 6 meters, the area is 3 x 3 x circumference rate. If the circumference rate is 3.14, it's 28.26 square meters.

What happens if we share this with two wings?

Divide half 14.13 by the circumference rate and find the square root of the further result.

The answer is about 2.12. The unit is meters, which is twice the radius, so 4.24 meters is the diameter.

In view of the reduced efficiency, this blueprint had a diameter of 4.5 metres.

The circular wings of "Taube" and "Taube Modified" look quite compact because they are seven meters in diameter.

For that matter, the overall height is about 30% higher.

"Speed is low, are you thinking?

Jen asks to confirm.

With more air resistance, it's not suitable for high-speed flight.

"That's right. It mainly assumes travel throughout and around town. specifically within" Avalon, "so"

"Well, that doesn't sound like a problem."

Easy to design if the purpose of use and the performance targeted are clear.

"We were just discussing creating a prototype and model that shrunk to a quarter."

"I see, that's good"

Jen also agreed.

The miniaturized model, influenced by hydrodynamic constants, beginning with air resistance, has different properties from the real one, but it was thought that the effect would be relatively small if it were a quarter.

"Oh, that's comforting to hear you say!

Zola Himmel said happily.

"We already have all the ingredients."

"I'm looking forward to that."

"We're finally going to work on the machining!

Jen decides to give her a tour, as Ciel Ajour says happily that she is going to be in member processing today.

"If Lord Jin will accompany you, it's a thousand manpower."

...... but Jen is not going to get his hands on it for now.

(First, take a look at the arrangement)

If there is any danger, it is not a rush to lend a hand with Reiko.

"We'll start with member machining"

The prepared light silver ingots are processed according to the drawings.

Basic machining at first.

Bars with predetermined cross sections, sheets with predetermined thicknesses are increasingly formed.

(Yeah, you're pretty skilled)

Jen grinned satisfactorily, as not only theory, but also practice seemed to be taking place.

The day ended with member processing.

Jen and Elsa are guided by Fione Fierce to the dining room for visitors.

Tomax Bartman was not there and a quiet private room was provided to allow Jen and Elsa to eat slowly alone.

Reiko holding back and Elsa sitting in the front.

It was a relaxing dinner without family water.

The dedication was of the Imperial style of Shouro, satisfactory both in quality and quantity.

Drink after-dinner tea, and indulge Jen and Elsa.

"... Brother Jin, did you have fun?

"Oh, right. I could see how those who make the times ahead were doing."

Elsa shrugs and laughs when she hears that line.

"Hehe, he's kind of like an old man"

"... right"

Jen scratched his head. And a pompous word.

"I still have something to do."

Elsa, who heard that,

"Mm, still halfway down the road.... Let's do our best?

"Right."

Jen replied with a laugh.
