The first thing Jin asked was the most basic of basics.

"You know the principle of a rocket engine, don't you?"
"Yes, I do."

Jin then decided to explain about the rocket engine he had found.

We must put this to practical use!

"The problem is the supply and control of the mana. ...... and the fact that it's an explosion means that it has a lot of propulsive force, so it won't be good at low speeds."
"The heat resistance of the engine is also important since it uses fire magic.

Arnold added to Jin's explanation.
"That is true. But this will contribute to increasing the speed of the aircraft!"

Jin is also hopeful that this could be an alternative propulsion system to the <

However, as noted earlier, he speculated that it might not be good at low speeds.
(Well, in that case, I suppose we could find a way to release the pressure of the explosion.)

There were several possible ways to do this.
The combustion chamber of a rocket engine ...... explosion chamber? Make an appropriate hole in ...... to release the pressure in other directions than the direction of the jet.

Wrap the explosion with a boundary to reduce the force.
Variable jet aperture (narrowing the aperture increases the jet velocity and widening the aperture decreases the jet velocity).
The following is an example.

Jin advises.
"I think it would be better to use an airship for the experimental plane. How much propulsion can be obtained by how many explosions, and repeat the process.

The control data is stored in magi crystals and can be applied.
Of course, control will be left to a special control core.

"Well, is it impossible for the pilot to control it directly?
"I don't think so in the beginning."

It was thought that if enough control data could be gathered, a conversion table could be constructed to produce output in response to throttle, which would make maneuvering much easier.

Somewhat surprisingly, Arnold is not very good at writing reports.
When Jin went to Arnold's room to go to the dining hall for dinner, he was struggling with the report paper in front of him.

Arnold stood up, leaving his report unfinished.

While research reports need to be written in a well-structured manner so that nothing is left out, reports are a little different.
