Magi Craft Meister

The first thing Jen heard was the basics of the basics.

You know how rocket engines work, don't you?

It's okay.

Then Ren decided to explain the [rocket engine] she found this time.

"Until now, rocket engines thought of had gained thrust by using the expansion of air due to" combustion. "But the rocket engines I found this time were explosive. "

……

"Causing small explosions intermittently and turning them into propulsion.In my calculations, I think we can get three to five times the propulsion of the "combustion type" that has been studied before. "

Oh!

That's amazing!

This must be put into practical use!

The faces of "Aeronautical Research" were suddenly motivated.

Jin-sama, please tell us what's ahead of you.

"Yeah.... This explosion is magical, so you don't need fuel or oxygen."Just supply "Free Magic Element (Ether)" or "Magic Element (Mana)", so there is no need for fuel tanks, and the overall structure can be simplified. "

That's true.

"The problem is the supply and control of magic elements (mana)."... and since it's an explosion, you probably don't like slow speeds because of the high propulsive power. "

Since we use fire attribute magic, the heat resistance of the engine is also important.

Arnold also supplemented Jen's explanation.

"It will be that way." But this will help speed up the plane! ”

I'm sure it will be.

Even Ren is hopeful that it may be a replacement for the "Magic Jet Engine".

However, as I just warned, I was speculating that I might not be good at slow speeds.

(Well, in that case, maybe we should think of a way to relieve the pressure of the explosion.)

There were several ways to do it.

Rocket engine combustion chamber... explosion chamber?...... drills appropriate holes to release pressure outside the blast direction.

Cut the blast with the barrier and sharpen the force.

Make the caliber of the injection opening variable (increase the injection rate by squeezing, decrease the injection rate by widening)

and the like.

It was a future-proof technology.

"It looks like it's difficult to control..."

[Aeronautics Research] department manager Lower Eisker muttered as he framed his arms.

We'll need to repeat the experiment on the ground to retrieve the control data, and then use the experimental machine to retrieve the data…

Jen gives advice.

"I think it would be better to use an airship for the experiment."It's a repetition of how much propulsion you can get with how much explosion. ”

The control data is stored in magic crystals (magic crystals) so that the application is effective.

Of course, control will be left to the dedicated control nucleus (control core).

Hmm, can't the pilot directly control it?

I guess not at first.

Since the power characteristics of the Maguijet engine are linear, direct control was possible, but Ren believes that the Maguijet engine (tentative name) is unlikely to work well.

It was thought that if enough control data was collected, a conversion table could be constructed that could output output according to the throttle, and that would make it much easier to operate.

“Very well, let's use Lord Jin's advice and gather the data carefully.”

I want you to do that.

"In that case, it may be better to collaborate with Go Research on the control core part of the control data."

This is why Aeronautical Research has decided to jointly develop the Maggi Rocket Engine (tentative name) with Go Research.



It was such an evening that I decided to stay at Avalon's accommodation.

Reiko is relaxed, but Arnold must write a 'report' to the Cellulore Kingdom.

What was a little surprising was that Arnold wasn't very good at writing reports.

When Jen visited Arnold's room to go to the dining room for dinner, he was struggling in front of the report form.

"Arnold, this is going to be tough..."

"Oh, Jin. I'm not good at this..."

For now, why don't you go to the cafeteria?

"Oh, that's right..."

Arnold, who was invited by Jen, stood up with the written report.

Anyway, I've always been bad at writing reports.

"Hmm, I think I understand a bit."...... Cher, Arnold, have you really written your report? "

"Yes, as you say."

I knew it.

I also remembered Jen.

The study report needs to be written with a firm overall structure in mind so that it does not fall out, but the report is slightly different.

In the company where Nin was in modern Japan, when he went to a technology exhibition such as "○○○Shaw", he was supposed to report it in a report, but the boss who received it would dispose of it without even looking at it.

When she learned that, Jin learned to unwillingly and appropriately let go... "

Besides, Jen gives Arnold one piece of advice.

"Chel, can you help me?"

and.

To Cher?

"That's right. Cher's brains are amazing."Memory and composition are more than human beings.Arnold would know better. "

"If you say so, then so be it."But this is my job.... "

"Even Cher was made by Arnold.The work Chel did was as good as Arnold's. Hey, Cher? "

Yes!

In response to Jen's inquiry, Cher, who was standing behind Arnold as he came along, replied vigorously.

Oh, I see. Well, let me ask you something.

Yes, I'll take care of it!

It was Cher who replied vigorously at any moment.



What Jen said was a big win.

After dinner, Arnold, who had asked Cher for a summary, stared at the report, half surprised and half joyful.

Lady Arnold, it's over.

In the first 15 minutes of writing, a report covering 10 sheets of A4 paper was completed.

You were early, weren't you?

There is absolutely nothing wrong with the content.

Arnold was relieved to be able to file his report tomorrow.
