"Thank you, Jin-sama, Reiko, for your help!"

"Thank you, Jin and Reiko!"

Despite the Magi Detonation rocket engine explosion, there were no injuries.

This is thanks to the shield that Reiko deployed.

Reiko's reaction speed is the only reason why we were able to avoid it.

There was also a large hole in the roof of the laboratory, and the pressure blocked by the <> was thought to have escaped to the ceiling.

Onlookers had also gathered around the room after hearing the loud noise, and Arnold and Chelle were busy explaining and apologizing to them.

Arnold and Chelle were busy explaining and apologizing to the onlookers.

"...... I didn't think I had used it for experiments many times."

Jin is sorry, too,

"No, no, Jin-dono is not responsible at all. It was all our fault. I'm very sorry.

Roar Eisker, formerly of the Aeronautical Laboratory, and Rasnath Heilbronn, formerly of the Gor Institute, bowed their heads as the two people responsible for the experiment.

"It's true. Your father would have been in danger if I had not taken care of him.

"I am so sorry."

Reiko was furious, and Lois Eisker and Rasnat Heilbronn bowed their heads again.

Although no one was injured in this accident, it was a serious accident that could affect the prestige of the <>.

It is necessary to clarify the cause of the accident and to take appropriate countermeasures.

At the same time, it is necessary to increase the safety measures of the experimental facilities here.

A task force was set up before noon that day to deal with such a series of issues.

Of course, Jin is also participating in the task force as a consultant, giving advice on the construction of wards.

<, it would be unreasonable to hold Arnold, who took office today, accountable, so he was not blamed this time.

Still, Arnold said,

"I must reflect on what I could have done to point out the dangers and to manage safety," he said.

He said.

Gough and Rubina, as well as Eira, Gromma, Cachea, and most of the other members of the were working on the analysis of the .

Reflection and countermeasures are important, but we must not stop moving toward the future of technological progress.

"It's very clear when you put it in a graph like this."

"Goh is right. Knowing these characteristics will help us in our design work.

Horizontal axis: input, vertical axis: output. The graph shows how much propulsive force is obtained for the given magical force.

"Now we just need to see if we can expand this to a per-unit value," Jin said.

Jin said.

"Per unit, Jin-sama?

"Yes. The power output, the propulsive force, will depend on the size of the engine, won't it?

Yes, that's right.

"That's why we can't simply compare a Magi Detonation rocket engine with a Magi Aero rocket engine."

"Oh, I see. It makes no sense to simply compare a large engine with a small engine."

"That's what I mean."

For the purpose of comparison, it is easy to summarize them by some common terms.

"Then, let's divide by <>.

"That's the way to do it."

The "aperture" is the size of the jet.

Dividing by this means the output per unit area (or per unit aperture), which makes comparison easier.

Specifically, the output can be expressed as or <>, which makes comparisons meaningful.

The series of calculations for such a process will be omitted, but a recalculation of the characteristics was performed as suggested by Jin and his colleagues.

According to the calculations, the <> has a diameter of 30 cm and a power output of about 100 kN (10200 kgf = 1,200 kgf). 10200kgf = 1 0.2tf), so the output per unit caliber ...... meter in diameter is approximately 1 100kN (112tf).

The weight is about 42 kg, so the output per kilogram is about 2.38 kN (0.24 tf). The weight is about 42 kilograms, so the output per kilogram is about 2.38 kN (0.24 tf).

> has a diameter of 50 cm and a power output of about 300 kN (3,600 kgf = 30.6 kgf). The engine is about 300 kN (3,600 kgf = 30.6 tf) with a diameter of 50 cm. The power output per unit diameter is approximately 1200 kN (30.6 tf). The output per unit diameter is approximately 1200 kN (122 tf).

The weight is quite heavy, about 200 kg including cooling system, so the output per kg of engine weight is 1.5 kN (0.15 tf). This means that the output per kilogram of engine weight is 1.5 kN (0.15 tf).

In this way, it is interesting to note that the output of the <> and the <> are reversed in terms of caliber and weight, and this is due to the weight of the engine.

By the way, the engine of F-15 has a diameter of about 1 meter and a weight of 1500 kg. The thrust is 23450 pounds (= 10.6t f = 104 kN).

Therefore, the output per kilogram of engine weight is 0.07 kN (= 0.007 tf). This shows how heavy the engine is.

"You can see it clearly this way, can't you?"

"Right?"

"<> is light, isn't it?"

"That's its greatest advantage."

"The Magi Detonation rocket engine is a little heavier."

"I wonder if it could be made lighter if it were used only for short periods of time and not cooled."

Or if it's not manned.

"That's exactly how missiles were used when they were first discovered."

"In the end, the <>, which follows the principle but is manned, is better suited for airplanes."

Jin, who has been watching from the sidelines, thinks that it is amazing, in a sense, that no one has suggested the development of <> here.

There are still dangerous monsters such as Sea Dragon and Death Serpent, and they will invade the sphere of human existence.

In such cases, missiles are supposed to be effective weapons.

However, the members of the <>, whether they are aware of it or not, do not seem to be considering the conversion of the missiles into ...... weapons, at least for the time being.

Jin was relieved to see that the researchers of the , which aims at peaceful use of technology, are not considering the use of the technology for weapons at least for the time being, although that is a dangerous aspect.

Meanwhile, the <> was also putting systems in place.

Of course, it is the management system of the <> and the newly discovered mines.

The activities in the mines are particularly active here.

After all, it is a mine of the rare metals < and .

Incidentally, the < mines we found along the way seem to have a slightly lower priority. The market price of lead is so low that it's no wonder.

"So now we have done our part."

Rhodes and his team are holding a launch party for the temporary base, which is to be pulled out tomorrow.

Kondak, thank you for your hard work.

"I'm sorry, Kondak." "Yes, I am. I feel like I've been taken advantage of.

That's how much they depend on you.

I guess that's one way of putting it.

It was a pleasant party.
