Magi Craft Meister

On August 8th, when the hot sun shines, Jens was coming to the village of Rihoto.

To mount and experiment with a prototyped air injector (air jet) on a ship.

"Looking forward to it!!

"Really."

Paelova Sondvik and Jed Aramordo are with us.

In the village of Rihoto, the great men have come to the big picture, so there's a fuss.

"This is, Master Administrator, welcome."

While Paellova and Jed were receiving greetings such as, Jen, Eira and Kathea moved to the dock.

Three people go around the various ships, large and small, connected there.

"Hmm, you don't have a very good ship..."

"Why don't you stop worrying about the good and bad of the ship, Jin? Why don't we just pick him a new boat as soon as we can?

"That's right, Mr. Ginn. This is only a prototype..."

The two of them told me, and Jen and I re-thought, well.

"Okay. … so let it be that way"

Jen pointed to a ship that seemed to be the newest.

"Yeah, wouldn't that be nice?

"It looks like it's a good size, and if you ask Master Paellova, you're going to have permission soon."

"Lord Jin, Lord Eira, Kathea, what do you say?

Rumor has it, Shadow, Paellova has arrived. Jed and the village chief are with us.

"Ah, yes. I wonder if that ship would be appropriate."

"Hmm, is that it?... Village Chief, what do you say? I told you the use was on the way."

"is, there is no difference"

"Okay.... Lord Jin, you can use it"

"Thank you"

"... this is, again... wow..."

"As I said..."

……

Paelova, Jed, and the village chief stared at Jen with dismay as he 'slightly' earnestly remodeled the ship.

Eira and Kathea seem pretty used to it over the last few days, at least not to the look on their faces.

"Now, all right"

Jen modified the ship with a wide range of shallow bottoms with a total length of 4 meters and a width of about 1.5 meters.

Two prototyped air injectors (air jets) were mounted on both sides of the ship.

In other words, we are going to use it as a Wind Magic Thruster instead of an Aquathruster and move the ship.

This is because it uses a magic formation rather than a magic crystal (Magic Crystal), so the control becomes a huge mess, which makes it an engine that sprays air instead of water.

In addition, it has not been possible to incorporate the junctional function of solid suction prevention.

In that regard, it would be mostly sand and dust even if it were solid in the air, because it would be ready to be fixed in case the birds or something jammed up.

Finally, a guided circuit board (plate) carved with a magic formation with the effect of "Water Avoidance Boundary" was attached to the bottom of the ship. This reduces water resistance.

"Dear Paellova, I will be commissioning the ship from this, will you be aboard?

From above the ship, Jen called out.

The ship seats five. Jen, Ayla and Kathea are on board, so we have two more people.

"Hmm, I want to ride, but I don't think Jed's gonna forgive me"

"I'm sorry, Lord Jin. We'll show you from the shore."

"Okay."

Jen sits in the center of the ship. Eira lowered her hips near the bow and Kathea at the stern, respectively.

"'Startup'!

Jen activated the wind injector (air jet). The ship moves slowly.

"Oh, it moved. It moved."

Eira shakes.

"Kathea, cut the rudder as I taught you."

"Yes."

A kachair sitting at the stern cut the rudder slightly and manipulated the ship in a direction away from the shore.

"All right, we're going to increase speed."

Because the air injector (air jet) made this time cannot be controlled in detail, the air volume is adjusted using a lever rather than an "instruction".

Either way, Jen wanted to be able to use a wire cable or a rod to operate like an accelerator.

Still, the output was considerable, allowing the ship to run at about 10 km/h against the river flow.

It seems like it could be reached around the village of Lileaz in the middle basin of the river Nocina.

"I wish I could be a little more powerful..."

The output is proportional to the input.

The input in this case is a free magic element (ether).

Jen reproduces the Magic Converter (ether converter) in a magic formation, but its efficiency ranges from one fiftieth to one hundredth when using the Magic Crystal (Magic Crystal).

"Even if I want to improve the quality of the guide board (plate), I don't have the material, and I don't think I can do any more."

"No, no, Jin, this is pretty good stuff! Look at the shore. He's looking at me like Paellova rode."

Eira has a bad mouth. If I know I can't hear you, I'm calling it off whoever it is.

Jen looked at the shore with a bitter smile.

"Oh, really.... but this guy should be improved a little bit too"

"Well, as far as Jin says so, I guess the prospects are already standing, huh?

"Sure. I'd like to increase the caliber a bit and increase the speed of the breeze that blows out"

This method cannot naturally proceed at speeds higher than those of breezing winds.

Jen therefore intended to increase the speed of the ship, so as to increase the speed of the injection.

"I'll try. …" Deformation ""

Jen widened his caliber by about 1.2 times.

This is the limit because of the combination of material thickness and strength. But.

"Ooh!?

It increased its velocity enough to feel physically.

"1.2x caliber means 1.44x in area. So the amount of air you inhale is 1.44 times higher, so the rate of injection is 1.44 times higher."

Kathea instantly calculated and said so.

"Oh. Well, I know it doesn't always work out, but I'm pretty sure it's about 1.4x."

At least, the momentum to cut the wind is clearly different.

I want to go back to the middle basin.

When Jen said that, Kathea just started calculating.

"The river flows around here as 3 km/h, and the current speed is approximately 14 km/h. The flow in the middle basin is about 15 kilometers an hour, so we have to make it a ship that can get at least 20 kilometers an hour."

"Right, not so much"

"If you do that, you want the caliber ratio to be even more than 1.2 times what it is today."

It can be seen that an area ratio of 1.25 times the caliber ratio is required at 16 divided by 20. About 1.118 in its square root if it's diameter. I said 1.2 times less efficient.

"The kachair is amazing. How can you calculate so quickly?"

Eira was impressed sitting near the bow.

"All right, let's go back"

"Yes."

Kathea cuts the rudder with one eye. It is a flat shallow bottom ship, so stability is good.

The ship, which has turned 180 degrees, now rides the stream of the river and runs at 17 km/h.

"This is a good prototype for a wind injector (air jet). And then there's piloting."

"Sounds like you need to figure out what's easier to maneuver!

"Exactly."

Jen also agreed with Eira.

Jen had never operated an actual motor boat either, so he decided to split it that it might be his own method of maneuvering, but that it would be easier to use.
