Magi Craft Meister

81-07 Engine prototype

At dawn, on March 3rd.

Arnold will remain a temporary instructor at Avalon for about a week.

Jen decided to return to Penglai once.

At that time, I will stop by the celluloid kingdom and tell Arnold that I will be the instructor, and I will hand over a report summarizing what has happened so far.

Well then, Arnold, I'll see you later.

Yeah, thanks, Jin.

I can be contacted by my "Friend's Bracelet" if necessary, so I have to do this kind of separate action.

I don't have to worry about it because it comes with Chel.

Thank you for taking care of me, Jin-sama.

"See you, Jin! Come visit me once in a while!"

Yeah, I'll see you then.

Lower Eisker and the other members of Aeronautical Research and Eila are all over the place, and Jen embarks on Hurricane.

While watching the 'Hurricane' float towards the sky in the morning,

Someday, I want to build an airplane that can fly faster than Lord Jin's [Hurricane].

And Lower Escar was all alone.



Hurricane Jin arrived in Esaias, the capital of the Cellulore Kingdom, in an hour.

The familiar Balloon Squadron quickly gave me the air route, so I could land with ease.

Welcome, Jin-sama.

And Prime Minister Dyne was greeted.

“Since Arnold is going to be a temporary instructor at Avalon, I have the report and the previous report.”

"Oh, thank you."

That's why Jen moves to the small conference room and submits the report.

"Hmm, I see... you've been doing a lot of things in this short period of time. That's right, Jin-sama."

The prime minister glanced at the report once it was closed.

Temporary instructor, right?

That's right. He's going to give a lecture on what was going on at the time of the [Magic War].

“I see. So will you send some people from my country?”

"I think that's good."

A high-speed airship made in the Kingdom of Cellulose arrives at Avalon in about three hours.

There is also a way to connect with the transfer magic circle, but it was not realized for security reasons.

Currently, only the "Avalon" (including the World Guard) facilities have transfer routes. (Excluding Phnom Penh Island Relationship)

There is no law, but it is self-regulatory.

(Oh, I wonder if this time could be shortened by [Maggie rocket engine (tentative name)].)

It was Jen who had such hope.

After a few other exchanges, Jin resigned from the royal castle.

Both the Prime Minister and the King seemed to be very busy right now, so they took care to stay out of the way.



...... is before the founding, and Jen wants to study the [Maggi rocket engine (tentative name)] herself.

So he hurried back to Penglai Island and took it to the workshop.

As usual, my assistant is Reiko.

"First, let's make it exactly as it was... or as it was over there."However, in one-tenth of a centimeter

It's an engine that uses explosive magic, so it's Jen who gets cautious.

"The material also uses Adamantite to ensure sufficient strength."

"Okay.... what do you use explosive magic for?"

"I see... first of all, I wonder if it's the [Firebomb]."

After deciding the specifications, Ren and Reiko proceeded with the work and completed the prototype engine in about 30 minutes.

Combustion chamber or explosion chamber (?), the jet, the conductor for supplying magic elements (mana), and the "Firebomb" magic formula (magi formula) engraved inside the explosion chamber.

The spout has a caliber of 5 centimeters and a total length of 15 centimeters.

Secure this to the test bench in the workshop.

This test bench is designed to measure the thrust of these thrusters and is made by Magi Adamantite.It can withstand thrust up to about 10 tons.

To be even more cautious, it is necessary to deploy a strong physical barrier (solid barrier) around the experiment.

You'll have to keep a record of your behavior. [M]

Reiko acts as a substitute for the control core.

Reiko had decided that her processing power would be too much.

Well then, let's start it up (start).

In response to the magic key word (keyword), "Magi rocket engine (tentative name)" came into motion.

"Whoa?"

A red flame is blowing from the spout.

The thrust meter mounted on the test bench indicated 200 kilometers.

"Two hundred kilos at this size."Amazing... can you stabilize Reiko at 100 kilometers? "

"Yes, Father."

Since it was the first control, there was a time lag of about 2 seconds, but the thrust meter display was almost stable at 100 kilometers.

Alright, now let's increase the output bit by bit.

"Yes, Father."

With Reiko's control, the thrust gradually begins to increase.

The flame coming out of the spout also starts to grow longer and longer...

"150 kilometers, 200 kilometers, 250 kilometers, 300 kilometers, 350 kilometers, 400 kilometers..."

The jet flame was about 50 centimeters.The color also turns from red to yellow, and the temperature can be seen to be increasing.

"If you go to 500, 550, 600 kilometers... Reiko, keep it that way until 1000."

"Yes, Father."

The Maggi Rocket Engine (tentative name), which has increased its output almost linearly (linearly), maintains a thrust of 1000 kilometers.(this is equivalent to about 9800 N)

After holding for 10 minutes, Ren ordered a sudden stop.

"Stop (Stand still)"

The flame goes out at once and the "Maggi rocket engine (tentative name)" stops.

Jen immediately checked each part.

"The temperature is... 1100 degrees Celsius." It's still expensive. "

Since the main body of the engine is Adamantite and the test bench is Magi Adamantite, there is room for the melting point, but Ren thought that thermal measures would be necessary to mount this on actual aircraft such as balloons and airships.

"The output is enough." Reiko, how about control? "

"Yes, Father." I tried it, but a small explosion at 0.2 second intervals is more difficult to control than a medium explosion at 1 second intervals, but the output is stable. "

"I see.... Old Man, have you noticed anything?"

"Yes, Master (My Lord). I'm concerned about the flames emanating from the spout."Flammable materials will ignite. "

That's for sure.

That said, Ren doesn't care much because he remembers the image of an anime robot flying while jetting flames from a rocket engine mounted on his back when he was at the facility.

Rather, I think that's what a rocket is.

That said, there is no doubt that heat is likely to be a necklace to popularize it.

"Let's think about it again."

First of all, it is a phenomenon called "explosion".

Rapid chemical reaction with destructive power.It is said in the dictionary that the volume increases with gas, sound, heat, and light.

This time I used "Firebomb".

This is a magic that changes the magic element (mana) into sound, heat, light, and rapidly expanding gas.

The magic element (mana) that changes into sound, heat, light, and gas disappears in a few seconds (or loses its physical properties).

From here on, let's see if we can use some more efficient magic.

[Magic Engineer [Magic Craft Jazz]], Jin started the study...
