Otoko Nara Ikkokuichijou no Aruji o Mezasa Nakya, ne?

Finally, the prototype of the manned hot air balloon was completed.

It took me a while to interrupt the manufacture of rubber protectors, boots, etc. that I would pay the Knights in the middle of development, but I don't think I had a choice but to do a good job testing them on drones, etc. and I needed more than a year after ordering the development.

There's not much wind for you today.

Waiting for the sun to set, he climbed Mount Velos with production reps Diane and Luke, plus about a dozen Knights.

Folded hot air balloons, gondolas, etc. weigh quite a bit.

Hot air balloons are huge with a diameter of about six meters, and the weight of the balloon portion made of rubber pull cloth is about 50 kg.

It is already quite elongated even if folded to the limit, its shape and softness make it quite difficult for one or both of us to carry mountain paths.

Because only the balloon portion cannot be disassembled to maintain airtightness, it is just enough weight to require a single carriage.

Today's first test is the one I try unattended, but I've done the test myself many times already, and this is the second time I've ever hit a test using this balloon.

If there seems to be no problem with the first test, I'm going to drop it off immediately and give it a try first.

Upon climbing to the middle abdomen, he arrived at the test departure site, where he had repeated scatter tests on a drone.

Assemble the balloon quickly.

That said, connect the lower part of the balloon with the gondola and tightly tie a rope about 150m long to the lower part of that gondola.

And the other side of the rope ties into a stay anchored to a big stump left near the center of the vacant land.

There are other similar stumps on all sides of the square to deter rotation and safety, against which it ends with a slightly longer rope stretched from each corner of the bottom of the square gondola.

The gondola is about 1 m deep, so that an empty opening comes at the bottom of the balloon about 2 m high from its bottom surface.

"Is that really what flies through the sky?

"I said fly. Last time Barts or Mirinda went, she flew..."

"Heh."

"But he said he hadn't caged that before..."

"You said the captain was going to be in that cage."

"What about flying?

"You idiot, it's easy to tell the formation of the opponent during the war, and you can build a very expensive object everywhere. This guy is amazing."

Knights members expanding balloons whisper as they follow Diane and Luke's instructions.

The work itself was not that difficult, so it was done immediately, and the next thing I knew, I had the soil packed in a small hemp bag containing about 10 Kg of soil in about one bag.

The number is the same as in previous tests, 20.

……

…………

Even though Diane and the others were there, the time to assemble and deploy for the first time was just over 40 minutes, because it was Wright's ninth witchcraft plus a few decades.

This is my first time connecting with Gondola, but it hasn't taken me ten minutes to do so.

Therefore, whoever is asked to do the work is more or less the same.

If you get used to it, you're going to be able to do less than 15 minutes in total.

"Ready."

At the end of the day, Value, who finished checking the dirt bag tied to the side of the gondola, looks back and says:

The Vice Knights Value has also taken part in all the drone tests that have been done so far, so I have not let them touch the actual work after the first one.

The test also includes measurements of prep time by those who touch the balloon for the first time.

"All right, here we go"

When I said that, I stuck my right hand into the balloon opening at the end of the gondola, which was shaped to put me to sleep on the side.

……

Bashu ~!

The balloon swelled more and more with quite a few noises, and rose less than a minute later.

At the behest of the Values and Dianes, the Knights attach to the Gondola and wake the Gondola as the balloon rises.

I'm creating hot air with level four wind magic and fire magic and releasing it as I add and subtract it, but I'm getting used to it, too.

Of course, the diameter of the balloon is 6m, so even level four wind magic can be done to pamper in an instant, but I won't do it, or I can't.

I used to try that on my first drone, a balloon test about 2m in diameter, but the balloon did swell in one shot, but it ripped.

It's usually caused by the use of elemental magic that would be fine because of the big holes in it.

From the second test, which I challenged by reflecting on it, to the present day I have tried to release heat at a constant rate by making the release rate considerably less and more pleasant.

The temperature of the air emitted is about 100°C.

Especially since I'm the one who can know the magical magic in the magic precisely digitally, I can just say 100°C or something.

It feels like a little hot sauna, so it's not unbearable for anyone to do it at this temperature.

I just calculated the diameter of the balloon so that it could rise quite a bit at this temperature.

The weight of the balloon + the weight of the gondola + the weight of the passenger + the weight of the ballast is considered to be about 300 Kg.

The breakdown is 50Kg of balloons, 100Kg of gondolas and various sorts of socks, my weight without armor 80Kg, and likewise the weight plus ballast of Guine without armor (about 140cm tall).

The monkey calculation that the temperature of ambient air starts to float at about 104°C when calculated at 20°C on the evening of this period, with atmospheric pressure of 100,000 Pa, the average molecular weight of air of 29 g/mol, and the gas constant of 8314, but even if the figures could be accurately measured, they would vary from 104°C to around a few °C, and that's fine.

But the truth is that people weren't really put on board because they were scared until they succeeded in several unsupervised experiments because of the assumption that the composition of the air, atmospheric pressure, etc., was the same as Earth.

It should be noted that there is no precise thermometer, so there is little to be said about the details, but it seems that the composition of atmospheric pressure and air is somewhat different from that of the Earth.

Maybe the molecular weight of the air is a little more than that of the Earth.

After all, is there a mixture of strange ingredients?

Though it may just be that there is less nitrogen and hydrogen with low molecular weight (which can be ignored because it is originally very low) and more oxygen, carbon dioxide and argon with high molecular weight in comparison.

Especially since this is even a story that consists of assuming gravity is the same as Earth, I think it's more likely that gravity is different... maybe both are different.

That's right, the balloon is totally up and floating almost directly above the gondola.

All you have to do is use Flames Lower's magic carefully to warm up the air in the balloon.

Now we're holding Gondola down for ten, but it's time.

Let go of one hand at a time and count to five with the flames of Flames Lower stretched to about the center of the balloon where there are four left.

I walked away from Gondola and let the four of them get their hands off me.

The balloon, whilst subtly rocking left and right, was fastened to the earth, floated and floated.

"" "Oh!

It immediately began to rise at a good rate.

I rush to jump onto the rope that was stretching from directly under the gondola.

No, a total of one or two from around the gondola, I could have jumped on the ballast that was tied with strings and draped, but that one's a thin string, so I thought if I jumped, I'd cut it.

and soon the rise stopped and this time moved on to a rather slow decline.

And the soles of my feet touch the earth.

However, I don't feel like I'm stepping too firmly on the ground.

I guess because the moment my feet come into contact with the ground, my weight will be dispersed between the ground and the balloon.

What doesn't rise is that the overall weight of the balloon, including mine, is slightly outweighed by the buoyancy of the balloon.

Something to blow even a little strong wind would easily drag you down.

I called three Knights who looked lighter than me and let them hold the rope in my place.

There is a bottom surface of the gondola floating about three meters above their head.

I let the three of them pull the rope, slowly lowering the balloon.

Everyone stopped by and held me down on the edge of Gondola without me having to tell them.

I still have more than eight ballasts, so I'll let that go inside the gondola additionally.

Now I think it's roughly 80KG, so it's pretty much with me on it.

And of the ballast that was tied around the gondola, he made me throw away the contents of two bags that were diagonal.

There must be two ballast bags of buoyancy in the balloon right now.

"All right, take your hands off me one by one slowly"

The balloon rose, fuzzy, and now it's time to start making slow rises.

Is the speed of rise about 20 cm per second?

Good thing this is a windy day.

Looking up for a while, the rise stopped at about 15m altitude, and after about 30 seconds, it moved on to a slow decline this time.

The temperature of the air inside the balloon must have dropped.

Damn, it looks like we need to do some temperature-regulation, and we're going to need quite a bit of getting used to it...

I want a temperature sensor or something... something that wouldn't come out conveniently in the labyrinth or something?

I guess not.

I've never heard of anything like that.

That's right, and when the balloon comes down, we'll try to get it up in the air again.

We need to check the strength of the connecting cord, etc.

No, of course it's been confirmed, right?

But I've only done tests on the ground, and I'll still need tests on the ground.

Darlings Palace.

Great Hall.

About once every two to three months in the Kingdom of Davis, a ball hosted by the King is held, and tonight is that day.

"With that being said, there seems to be less people in the military tonight."

"Oh, sure if you ask me..."

As usual, about 20% of the participants are occupied by senior military officials, but on this day, none of those in a high position in the military participate as one, mostly civilians and unarmed nobles.

"There have been several sudden supply and escort plans recently, and the military have been running to them these days... Didn't you know Viscount Yamil or Baron Doge?

"This, my Lord Count Garca. It's shabby.... Regardless of the sudden replenishment plan, when it comes to the convoy plan, was it also a huge victory on the front line somewhere?

"I haven't heard those stories either..."

The nobles began their conversation with those who were not here.

"No, I'm not sure I'm saying it either...... You just heard those rumors. Tonight I walked over to the ball for confirmation about them... and apparently the rumors are true."

"Hmm. But I also don't hear about the army's massive collection of food and other supplies..."

"... No, the wheat price movement has been a little odd here lately. Even when the wheat from summer pruning begins to appear, the price drop is slight..."

The cereal consumed primarily as food for the army is wheat.

Typically, the majority of them are paid in kind as taxes.

The surplus is often returned to the market through chambers of commerce in and out, with winter sprinkled wheat leaving around April in the Kingdom of Dabus, a temperate climate close to the subtropics, and spring sprinkled wheat is harvest time from summer to autumn.

Therefore, it is normal for wheat prices to be on a downward trend from about May to about November, and it is around this time of year that prices fall the most.

"There's no story out there that some chamber of commerce is buying up big mouths, and buying a little bit from various chambers of commerce?

"Maybe that's why it's hard to fall, but why?

"This was... something on the front line"

"That's what I thought. I joined in to get some information."

"I see."

"With that said, Your Excellency's eldest son, aren't you an adult next year? My second daughter, who will be an adult next year, has also been brought here today, and if you don't mind introducing her..."

"Oh, let me introduce you to my oldest daughter too"

"Ha. Ok...... oh my son, you're dancing with some courtier now. When that's over..."

Gabagaba was also a good place, not just in the Kingdom of Davis, but in this era of aus, such as information management and control, as on the medieval planet.

"All right, get your hands off me"

The balloons that put me on float soundlessly as the Knights let go of their hands that were holding Gondola to keep her from rising.

At that moment, I felt the golden balls shrink with Hyun.

I didn't feel it when I cling to the rope in the test earlier, but things are different.

It's been decades. I totally forgot, this feeling.

But that's a flash, too.

Balloons began to rise more and more.

The altitude immediately exceeds 10 m and quickly reaches about 20 m.

The trees around the test departure site are passing by.

After two test flights with drones today, we conducted manned flight tests as planned.

"You rock quite a bit..."

Looking at the lower boundary, the solitaire leaked.

Unlike what it felt like to be watching from the bottom, the gondola hanging with the eight outlines connected to the balloon actually feels like it's shaking slowly to flutter a bit because the center of gravity isn't exactly stopping by.

The whole balloon just doesn't spin because of the wind, but I wouldn't say the ride is very comfortable.

Send your gaze around.

Earlier on, the sky was still subtly bright, even though the sun had completely set.

Is it the city lights of Beglitz that are blurring in the north?

Other than that, the ground is almost dark, no matter where you look, and the location of the city or village is not well known.

If it's this dark, it's probably because nowhere but Beglitz's restaurant and drinker still lights up the lights.

Somehow, I get the feeling of a dull upward force.

I unwrapped one sandbag that was loaded on Gondola and dumped the contents outside.

Did I hit the guys downstairs?

Mmm.

Lifting power returned.

He then looks up over his head and stretches the flames rower fire inside the balloon.

Slightly later the balloon began to rise even more forcefully.

"Like this..."

I'm surprised you're going up too steeply to exceed the strength of the rope you're tying to the stump on the ground.

Altitude 40m.

Though the middle belly of the mountain, there is no fear at all that it is still about this high.

Is it because it's dim?

There began to be voices downstairs with Values and Dianes giving instructions to the Knights.

I guess it made him start pulling near the quadrilateral stump so that the rope for suppressing the rotation of the balloon wouldn't get lazy or tangled.

Changing the orientation of the body in the gondola is quite shaky, but to this extent the fishing boat is more shaky so it is not a problem at all.

"If this is... you two or so can switch places sufficiently..."

Mm-hmm.

Somehow, but I feel like I'm losing my upside again...

One more time, I released the ballast.

The balloon regained its ascending power once now.

While doing so, it finally seemed to reach the rope's limit altitude, and the balloon rocked heavily this time.

"Wow!"

Drop your hips and grip the edge of Gondola desperately.

For a while, Gakungakun kept shaking, and the shaking subsided in one minute.

I feel very little about the transverse wind, so even if it is flushed, it is not a big deal.

A peek directly below reveals what looks like a test departure site a little further away.

... but it's far from spectacular because it's getting darker and darker.

I'm telling Mizuchi to do a flight test at this hour, so would you be looking up at this one from the mansion by now?

Because of this, I had also chosen a windless evening for all the unmanned flight tests I had done in the past, but I could never see it because I had made it to an altitude that did not exceed the top of the mountain even at the first glance.

Well, I didn't even put a gondola on the test before, and the balloon part of the balloon is black, so if it starts to get dark, it'll be hard to see.

It's better than it looks bad, and I can say it's just fine because I'm after it originally, but it's a shame you can't show Mizuchi my first flight to remember.

A slow breeze stroked his cheeks while Gondola made a squeaky noise.

Since the endurance testing of ropes and connections has been repeated sporadically, there is no strong anxiety.

But scary things are scary.

It would be about 120-40 m in altitude.

With this level of altitude, even if I jumped, I really think I could use wind magic to land without any major injuries.

But scary things are scary.

"Should I not tie a rope poorly?

Let me put it that way, whatever the altitude, the path is windy.

In the worst case scenario, Dabus will fly you away.

If we're going to fly without rope, we're going to do it in the mountains north of the territory, like Mount Weed and Mount Bashkel, or we're going to have trouble earning altitude, but that's what we're going to have to do around the middle of the territory.

Hmm?

The wind?

That's right.

Ultimately, I don't have enough magic power (MP), like me or Mizuchi, because I want to be able to operate with just normal people.

Tests that give some thrust to balloons, such as my use of wind magic in certain directions, are scheduled for next time.

Well, the test is a success.

It's time to get off.

I opened the mouth of an empty hemp bag for the ballast and soiled it out.

At this level, even the magic of the earth is easy for people who can use it at level three.
