Magi Craft Meister

Jin explains the purpose of the visit to everyone.

"I heard that a new invention was made at Gorgon, so I came here."

I see.My ears are fast. "

It was Eira who impressed me.

"Well, I don't know the contents at all, but what kind of invention is it?

"What, is that so?... that's it. "

What Eira pointed out was a balloon.

At first glance, it looks like a helium balloon with no freaks.... but...

"Father, that balloon looks a little more buoyant than a helium balloon."

"Yes, ma'am, I think you're right."

Reiko and Hope saw through the particularities of the balloon.

"Oh, that's right.Yes, that balloon boosted our buoyancy.Not hydrogen, of course. "

Hmm?

Typically, balloons are filled with airframes that are lighter than air.

By the principle of Archimedes, the buoyancy of the "difference in specific gravity between air and gases in the balloon" multiplied by the "balloon capacity" can be obtained.

Hydrogen is the lightest gas to be filled, but since it is flammable and has caused major accidents on Earth in the past, helium was used as the next best gas.

"Gases that are not helium or hydrogen?No, there's no such thing.What if... maybe it's a 'vacuum'?

"Awesome! Jin, you got it!Sasuka is "Magic Engineer Magikraft Jazz"!

"Oh no... it was just a guesswork... I see, a vacuum..."

Hydrogen and helium also have a "weight", so the amount of buoyancy drops.

In other words, a "vacuum" with nothing is the lightest.

However, if the vessel is vacuumed, atmospheric pressure 1 atmosphere = 1013 hectopascals of pressure will be applied and the lower strength vessel will collapse.

However, containers with a strength that can withstand one atmosphere are "heavy".The more I can't float...

Therefore, a container that withstands a pressure of one atmosphere while vacuuming the interior... If the balloon has developed an "airbag", it would definitely be a "new invention".

"Maybe... 'Physical barrier'!

"Again! That's right, Jin!!

I admire Ella, but if there is a real example in front of me, Jen can imagine it.

But Ella and the others who came here on their own were just as good.

"Oh, there's a real example, and if you give me a hint, I can imagine."

"No, it's not."

It was Jen who was told by Ella.

"Anyway, I used the Magic Team to deploy the physical barrier into the airbag and let the air out."

"Haah... that's a great idea.You wouldn't have thought about it anyway.... "

"Well, it would be easier for a gin to build an aircraft with more performance than a balloon.I don't think it has anything to do with that idea. "

"Hmm... I guess so..."

Magic Engineer Magikraft Jazz also had a bit of a problem.

Anyway, now the prototype balloon is floating in the sky.

It looks like Golem is on board.

"A lightweight golem developed for balloon maneuvering.Reaction speed, visual acuity are important, power is low. "

"Isn't that nice?It gives you performance specific to your application. "

Jin also looked up at the balloon.

The propulsion method seems to be "injection thruster (jet thruster)".

"The next challenge is not to apply it to balloons, but to airships."

"Problem with flight speed."

That's what I'm talking about.

At present, the speed of the balloon is about 20 kilometers per hour.It's about the speed of a bicycle.

Spherical airbags have high air resistance, making them difficult to speed and susceptible to wind.

"Hmm... why don't you flatten it instead of elongating it?

Huh?

It is easier to make a pancake than to make a "physical barrier" a cigar.All you have to do is combine the two dish-shaped boundaries... the convex direction is up and down...

It was thought that the air resistance would be greater than the cigar type, but smaller than the sphere.

In addition, the pancake type seems to have good stability.

"I see, there's room for reflection.Thank you, Jin. "

"No, I'm glad it helps.By the way.... "

Jin confirms the most important thing... 'safety'.

"What about the stability of the physical barrier?

If this is an airbag filled with light gases, it will take time for the air to escape (unless the airbag is large and torn).

However, in the case of a border, if the magic supply is cut off, it will disappear, and the airbag will be instantly punctured.

If that happens... it's a crash.

"There are two systems of barrier generators in the Magic Formation."

I see.

Do not let air pass through, withstand 1 atmosphere pressure.

There are only two essential functions, so there is little free magic (ether) consumed.Also, there is no fluctuation.

That's why we can do it in a magical way.

If you have two systems, even if one is stopped, the other is working, so there will be no crash.

"Magic Formation" is super lightweight, so even if you install two systems of the same thing, it hardly adds to the weight.

"If we're going to make it bigger and increase the number of passengers, we're going to make it from three to four."

"That's reassuring.... and the pancake-type just now could be used as a parachute in times of emergency... "

I can't say for sure because there is a relationship between area and weight, but Jen said that Ella was impressed.

"No, no, it's amazing that you can list those benefits right away.It was helpful. "

I'm sorry.

That said, the balloon slowly descended and landed safely.

The non-Ella members who were talking to Jin rushed there and started checking a lot.

"Does Ella have to go?

Jin said that Ella shook her head.

"If I don't go alone, I won't miss it.Besides, it's more meaningful to talk to Jin. "

"I'm honored to hear that."

While doing so, the checks seemed to have been completed, and the rest gathered at Jen's place.

"Mr. Jin, I apologize for the delay in greeting you."

Roar Ayker, director of the Aeronautics Laboratory, greets first.

"Jin-san, I'm out of time.Let us know what you think later. "

This is Lasnart Heilbronn, Director of the GOR Laboratory.

He also greeted Zola Himmel, deputy director of Aerospace Research, and other acquaintances such as Kratos, Ragle Gutan, and Kumir.
