Magi Craft Meister

A plane carrying Merze.

It seemed that Gou and Rubina were motivated to recognize it again, Jen felt.

First, let's increase the area of the main wing by about 30%.

In that case, whatever the weight, the air resistance will increase.

"If I could increase the engine power by that amount....."

"No, I think it's okay to leave the maximum speed at this time."I want to emphasize those who exercise. "

In that case, maybe we can use the [Fowler Flap] to reduce the flipping (loop) radius.

"If the speed drops by 10%, the centrifugal force will also decrease..."

Well, let's slow down a little bit.

Listening as an observer, Jen felt the growth of the two exchanges.

So, sometimes I take advice and help to put the idea together.

There is also the idea of increasing the maximum speed only for a short time.

"Huh...?"

"Master Jin, is that...?"

"Come on, you two, think about it."

Y-yeah, that's right.

"Hmmm..."

It's like this.

Incidentally, one of the answers is "Use fire attribute magic only for a short time".The second is "Wind Attribute Magic" "Wind Hammer". "Part 3 is "Shorten the activation interval of the magic used in the engine".

Jen suggested that there were many other ways to do it.

How do you increase the power of the [Windblow] used in the engine?

Yeah, that's fine.

Hmm, which one is better?

Master Jin, I have one question for you.

What is it?

Yes. Um, if you use [Water Attribute Magic], you don't need heat countermeasures like Fire Attribute Magic, and I think [Power] is stronger than Wind Attribute Magic.

Yeah, I guess that's the characteristic.

But maybe [speed] won't come out, right?

Oh, Gow's right.

Water attribute magic has a large mass of water molecules, so the "power" due to its "weight" does not produce a certain "speed".

The same is true of Earth Attribute Magic (though I wouldn't try to use it as a rocket propulsion force).

It's the wind attribute that's easy to handle after all.

"That's right. However, Jin-sama's third [shortening the magic activation interval] has a limit..."

Currently, it is not shorter than 0.1 second.

Rather than a magic technical problem, it was interpreted that it would take at least that long to activate the [windblow].

"Ah, maybe..."

Huh? Did you come up with something?

”Yeah... hey, Jin-sama, it doesn't have to be one of the 'generating groups', right?”

"Oh, you noticed there."

Ah, I see.

Gou noticed that Rubina was a little late.

The point is that the "magic formula (magic formula)" for generating "windblows" should be engraved, and the "generating group" should be generated in parallel, with a time difference.

I'll reduce the vibration even more.

That's what happens.

"That's right." In that case, it is necessary to review the strength of the engine. "

Yes.

In the case of Ren, the safety factor was increased in terms of strength, so she was able to use it as it was. However, Ren decided that it was necessary to review the strength of the Goo and Rubina engines because they were lighter.

Since engine failure leads to an immediate crash, this was the only place Jen had to leave.



Following Jen's advice, Gou and Rubina decided to prototype and test the improved engine.

"Let's double the intensity."

That's good, isn't it?

"The weight is... I think it can be a little lower than double if the pressure is not applied."

"The injection nozzle part."

After all, Gou was good at these kinds of improvements, and Nen was looking at them from the side.

Rubina came up with an idea, Gou became practical, and the two of them improved their performance.

Such a combination was beginning to develop.

And that day to modify and adjust the day...... It's not like that, while drinking tea at 3 o'clock in the tea time,

"After that, I'll have you read the paper."

"......" I said.

"Is it a thesis?"

"Yes, I wrote this paper on the 'Wind Attribute Magic Rocket Engine' (tentative name), but it's still in draft."Therefore, I would like the two collaborators to read it and make corrections.... oh, Elsa has already read it and pointed out a few things. "

"... yes..."

That's what it is.

I started by having the two of us read the draft.

……

…………

Since it is not such a long paper, Gowe finishes reading in about 30 minutes and Rubina in about 40 minutes.

"... how about that?"

"Um, I know what it says, but..."

"... I don't know how to correct it..."

"Well, at first I guess so..."

Since you've probably never read a paper, I don't ask for much advanced things from the beginning, but I don't know if you don't understand the content.

After all, he is a 'collaborator'.

"... do you understand the flow of the paper?"

"Well, there's the title 'Application of Wind Attribute Magic to Rocket Engines'... and it says in the 'Summary' that the rocket engines were reproduced with Wind Attribute Magic."

"That's right. And?"

This time, I looked at Rubina and asked Jen.

Well, there was a 'Table of Contents', and the 'Preface' explained the purpose and background.

"Right. So?"

"In [hypothesis] and [theory], I touched on the mechanics of the rocket engine, the significance of using wind attribute magic there, and how to control propulsion... honestly, this was the most difficult place to understand."

I see.

Jen nodded alone.

The fact that Gou and Rubina-class talented people can't understand it is because the writing method is bad.

Although it was not specifically pointed out, Ren felt that it should be reviewed.

And then?

Now I put a question to Gou.

"It was' experiment 'and' result '. We'll talk about the prototype rocket engine here, with a detailed description of the experiment on the test bench and its data.”

Yeah, so?

"It will be 'Discussion' and 'Conclusion'.We analyze the results of the experiment to see what they mean, and we lead them to a conclusion. ”

Alright, I'll just have to say 'Acknowledgements' and 'Reference Materials'.

In the meantime, she seemed to understand only the liver of the paper, and Jen was relieved.

Alright, let's think about the 'hypothesis' and the 'theory' together.

"... yes..."

Yes.

While forgiving the reluctant Rubina, Jen recapitulated her hypothesis.
