Magi Craft Meister

Yeeeee!

Rubina's moody voice echoed through the workshop.

Since Ren was developing the "Maggi Rocket Engine" that reproduced the ancient technology at any moment, it was just a tiny hint.

It seems that he said he wasn't going to be angry with me because he was an adult anymore...

If you ask Amanda, her grandmother, she is still a child.

Aside from that, Rubina and Gow worked together to build a prototype engine.

It is a cylinder with a diameter of 5 cm and a length of about 10 cm, and it is shaped like a "pencil cap" with one end blocked in a hemisphere.

It was like the basic shape of a rocket engine.

I want to engrave the [Windblow] magic formula here, but what should I do?

"It's difficult... I think it's a good place to experiment and determine the optimal position."

There are two suggestions for engraving places.

One is a hemispherical tip.

The other is the inner circumference of the cylinder.Experiments will also determine which part of the inner periphery is good.

From the results, they were all one now.

Hmmm, I thought it would give me a little more power.

"That's right.... I think it's the combustion chamber of the engine... [expansion chamber]... I'd like to write it in the center of it."

"Gou is right." It looks like the most efficient place around here. "

"...... I think I'll have to draw it into the spherical [Generator] and support it with three or four support brackets."

"I see... let's do it."

Since the results of the first experiment were not as good as expected, the two of them lowered their tension slightly, but they proceeded with the work.

Elsa, who watches over them, smiles and thinks that she is still a child, even though her mood is fierce.

While Elsa was watching, they built a second prototype engine.

And experiments.

"... I did it!"

It's more powerful than the last time, isn't it?

"I think if you adjust it, it will still go up."

Yeah.

So I decided to give Elsa a little advice.

"The 'occurrence group' in? However, I think the air flow will be smoother if the nozzle side is conical rather than spherical."

Ah, I see! Thank you, Elsa-sama!

Let's do it now.

Nh, do your best.

With Elsa's advice, the two of them managed to take the form of the [new Maggi rocket engine] by lunch that day.



After lunch, Jen finished writing the draft report and confirmed the progress with the two of them.

Rubina makes an impressive report.

Hmm, you're doing pretty well.

“In the afternoon, do a detailed output test!”

"Okay, I'll be there for that."

Yeah, look, Jin-sama!

After moving to the wind tunnel chamber, Nin immediately began the experiment.

"Oh, that sounds good."

Isn't that right?

It's an honor to have you here!

Even from Jen's eyes, the prototype engine made by Gou and Rubina was good.

"If you're going to score, it's 95 points."

I feel like it's a very high score, but where's the negative?

"Did you name the inside..." "Occurrence Group" "?"Because the cross-sectional shape of the support bracket that supports it is round

"Ah...! I should have streamlined the cross-section too!"

"That's right. The other one is the surface roughness inside the engine."Because it's a prototype, it's a little coarse, isn't it? "

“Oh, I see. It's better not to interfere with the flow of air as much as possible.”

“You just need to know that. If you look at the whole thing, you'll pass without complaining."

We did it!

Rubina leaping and rejoicing, and Gou looking happy.

Shall we skip the model loaded with this?

I'll do it! I'll make a [Nile]!!

Praised by Jen, Rubina was very enthusiastic.

Rubina and Gou took her to the workshop.Let's make a plane.

Ah, wait!

Meltze followed.

Even though I can't use engineering magic, it seems that it's quite fun to just look at it.

Rubina and the others are making the "Nile" series, so it's probably a delta wing.You can expect a lot of success this time.

Jen is also looking forward to it.

"Good job, Elsa."

”Nnh”

Then Jen took Elsa, who had supervised both of them, to work.

After a break, I'll try to build the new Maggie Rocket Engine.

"Looks like Brother Jin."

The two of them went back to the mansion and had a little early tea time.

Daiki, Kokona, and Amanda were among them.

The tea is fried tea, and the tea soup is yakinikan.

Jin-sama, is she all right?

Amanda seemed a little worried, but Jen replied with a smile.

"Don't worry about Rubina. I'm growing up to be a good engineer.And while you're here, I want you to be a good daughter. "

"That's what I'm worried about the most... she's a little grumpy."

That's why you can stay here and get in touch with a lot of people.

"Can I stay here...?"

"I don't care. Hey, Daiki, Kokona"

"Of course, it's been a lot of fun every day, isn't it, you?"

"That's right, too. Rubina and Melze became good friends with Gou."

Daiki and Kokona were words with a soft smile that I could tell from the bottom of my heart.

"Thank you..."

That's what Amanda did.



Well then, let's do it for me.

I thought it was in the workshop underneath Reuzart, but because it was so narrow there, Jen was transferred to Penglai Island for a moment.

I'll be back by nightfall, and I've asked the old man to contact me like that.

What do you want to start with, Father?

Yeah, let's start with my prototype.

Gou and Rubina put together some theories, so there's no problem.

It has a diameter of 5 centimeters, a length of 10 centimeters, and a cylinder that is hemispherical at one end.It was the same as the Gows.

Gou and I made the [Generator], but I don't want to make it.

In the first place, when you release the "windblow", it does not release from the palm of your hand.

In general, [Windblow] is a phenomenon that occurs about five centimeters away from the source of the magic element (mana) in the palm of my hand.

In other words, there are parameters that determine the location and direction of occurrence.

It is terrible to demand that the two [Magic Engineer] [Magic Craft Jazz] do not do that.

Therefore, it was Jen who did not mention that point earlier.

Well, I wonder how much propulsion I can get.

After creating the prototype in 5 minutes, Nin sets it on a test bench and starts measuring the propulsive force.

All right, [Startup (start)].

The prototype engine spewed out the wind.

Alright. I knew it wasn't an explosion, so the power generation was slow.

Just like that, Jen gradually increased her output.

"It's finally a prowess test..."
