The prototype was piloted by Sky 1 to test its maneuverability.
The prototype was at sea, and after gaining enough altitude, it was ready to begin.
"Okay, let's start with a loop."
Jin is watching the loop on the monitor installed in the control tower.
The old man took this picture with his "Peeper" telescope.
"Whoa!"
Jin stared at the screen intently.
The prototype does a big somersault first.
No problem at all.
It continued to do a series of somersaults (loops).
The radius gradually decreases.
"Yes, it feels good."
The thrust-to-weight ratio of the prototype is well over 1.
In other words, the prototype has enough thrust to easily make a vertical ascent without any lift from the wings.
This also means that there is no danger of stalling and crashing.
"Okay, now let's turn horizontally."
After the vertical somersault (loop), the next test is the horizontal turning force test.
Again, the prototype showed stable maneuvering.
Other maneuvers such as Immelmann turns, split-S, horizontal rolls, and vertical rolls were also performed, but no abnormalities were observed.
"Okay, that's enough. Come back."
.
The prototype performed just as Jin had expected.
* * * * *
Jin decided to talk to Sky1 directly after his return and make the final modifications and adjustments.
"So, what do you think? Did you notice anything?"
"Yes, Master. If we use it, the control stick is a little light.
"I see."
As a golem, Sky Squadron is more than a dozen times stronger than a human.
Then perhaps a little more weight would make them easier to handle.
What else?
I pulled the clouds off the wingtips at very high altitude.
"I see. So there's turbulence. Should we keep it in this case ...... or should we try to eliminate it?"
Turbulence is not only a bad thing, but it is less likely to cause separation than laminar flow, and there are even methods to intentionally create turbulence at the trailing edges of the wings.
However, Jin has decided to eliminate turbulence.
The reason is that this plane is a rocket plane, not a jet plane.
It does not need wings to fly in the sky.
However, in the air, wings are effective, so they have been added as a minimum requirement.
"Are there no more wings?"
Yes, nothing in particular.
Okay.
Jin is now working on the improvements suggested by Sky1 one by one.
The turbulence generated at the wingtips will be corrected by experimenting in a wind tunnel.
"Maybe we should change the shape of the wingtips."
After that did not help much, he added wingtip plates, and it worked well.
The final modifications and adjustments were completed.
Finally, it was time for the mass production prototype.
In Jin's case, the prototype can be converted directly into a mass production prototype.
"Father, aren't you going to give it a name?"
"Huh? "Well, let's see... ......"
Reiko tells Jin to start thinking of a name.
Since we are going to mass-produce it, we should decide on a name for it instead of <>.
"Then let's name the new rocket plane ."
Swallow. It is because it is likely to reach the highest speed among the Horaijima's planes in atmospheric flight with normal engines (with the use of the force field generator, the spaceship will probably be the top of the list).
"Yes, sir."
Sky 1 also tested the production prototype of < and assured him that all the problems had been solved.
"Okay, let's get a hundred of these ready for Skye Squadron."
The aircraft is not a spaceship, but it can enter space on conventional engines.
It is 15 meters long, 9 meters wide and 5 meters high. It can accommodate up to four people, including the pilot.
It can use a laser cannon, a magic cannon (Magi Cannon), a paralyzing gun (Paralyzer), a magic bomb (Mana Bomb), and an electromagnetic induction radiator.
Equipped with a force field generator.
It is also equipped with a warp gate for emergency escape.
"Now is ready. Now all that's left is the engine for the spread."
What will happen if this is fitted with a popular engine?
That is the last test.
* * * * * * * * * *
Let's just write the result, it was successful.
That's true, because it was just a matter of reducing the power of the rocket engine.
"This is the one for the public."
There is no warp gate for escape. Instead, the crew will carry their own escape (personal transporter) (only for those related to Horai Island, this will not be open to the public).
"What about armaments? ...... Shall we make it possible to refit the armaments?"
We have decided to make the armament retrofittable.
This is not a fighter but a multi-role aircraft.
It will be used for public display of Horai Island's strength.
The reason why Jin is so concerned about publicity is because he intends to unveil it at <> in the near future.
"I'm also looking forward to seeing what the Aeronautics Laboratory will make. Oh, and we should introduce them to as well. ...... and ......"
Then he realized that he had left Erza, Goh, Rubina, and Meltze at Loisart.
"......how irresponsible it is not to show your face once ......"
There was a good reason for this, and when one incident was cleared up, the next one called for Jin ......, so I never left them irresponsible, but for them, the reason didn't really matter, and they must have thought they were left alone. However, Jin reflected that they would have felt neglected regardless of the reason.
So, Jin decided to go to Leuthart first thing tomorrow morning, local time.
"Let's go to ...... and show them < just in case."
So, Jin decided to use the mass production prototype as it is.
In that case, the pilot would be either Reiko or Hope.
I decided to have both of them pilot the prototype at least once, so I asked Reiko to pilot the prototype first.
Naturally, Reiko showed us how to control with her own hands.
Next was Hope.
Hope is another gem of Jin's work.
As expected, she was able to ride <> at will, much to Jin's satisfaction.
