"It's done."

 In the morning, three airplanes were completed.

 They are the exclusive planes for Reiko, Soleil, and Luna, respectively.

 The color scheme is a tricolor with a white base and red and blue stripes as accents.

 In addition, Reiko's plane has the nose and vertical tail painted in black.

 Soleil's plane has the same parts painted in gold, and Luna's in silver.

 Finally, it is time for the test flight.

 The plane takes off from the airfield behind the institute.

"We've added a warp gate for emergency escape, but don't overdo it.

Yes, father.

Yes, father.

Yes, father.

 All three of them said the same thing, climbed into the plane, and closed the windshield.



"Okay, go!"

"Yes! Engines are on! Power is good. All green.

We're taking off!

 The propulsion system is activated, and after confirming that there is nothing wrong, Reiko, Soleil, and Luna take off in that order.



"Yes, the take-off attitude is stable.

 Jin muttered with satisfaction as he looked up at the aircrafts.

 The three planes quickly disappear from sight.

"Let's go after them at the institute."

 Jin headed for the command center of the institute.

 The old man would display the images taken by the Peeper on the large magic screen here.

 Of course, you can also talk to him with .

Reiko, Soleil, Luna, how are you doing?

 Reiko reported that the three aircraft accelerated further and started to climb at an angle of 45 degrees.

 First, they started with the standard somersaults (loops).

 The loop begins with a large loop of 500 meters in diameter and gradually decreases in diameter.

 Finally, five consecutive somersaults (loops) were performed up to 100 meters in diameter.

 The speed has hardly decreased at all, and the machine is in good condition.

"It seems so."

 The next step is an aileron roll from level flight, i.e., a horizontal flight with a cone roll.

 Reiko and her teammates could handle the rotational speeds that would make a human's eyes roll with ease.

 The three planes continued to perform Immelmann turns (half somersaults, returning to a normal posture from the rear position) and split S (the reverse of Immelmann turns).

 Up to this point, the three planes are moving in perfect synchronization, as if they are connected by a thread.

 Moving on to horizontal flight, the three planes perform a knife-edge (horizontal flight with the wing at a 90-degree angle to the vertical).

 The model also cleared this test without any difficulty with stable movements.

 This proves that an aircraft based on a real aircraft design is aerodynamically superior.

 The three aircraft continued to perform a number of difficult maneuvers, all of which were successfully completed.

 This is a flight test in which Reiko, Soleil, and Luna are fitted with force-field generators that are synchronized to their respective aircrafts.

 It has nothing to do with aerodynamics, and allows any movement in three dimensions.

"Oh, that's not so bad."



 The main wings, which are used to generate lift, are an aerodynamic drag in this case, but the aircraft is able to align itself in the direction of flight, so it is not unnatural to see.

 The aircraft can easily make a very sharp turn, which may require several tens of Gs.

 Stopping in a vertical or horizontal position is also possible at will.

 And...

 And the three planes reached Mach 3, the limit of the wind shield.

 Satisfied with the better-than-expected performance, Jin greeted the three landing planes and congratulated Reiko, Soleil, Luna, and the others for their efforts.

"You did a good job, Reiko, Soleil, and Luna.

"Yes, father."

 Jin patted their heads in turn, and the three of them smiled happily.

 Jin then checked the aircraft.



"Everything seems to be in order, doesn't it?"

Read at https://w w w . m t l r e a d e r.com


"Yes, father. "Yes, father. There was nothing out of the ordinary.

"I see. Did you notice anything?

Well, the rudder seems a little off.

Read at https://w w w . m t l r e a d e r.com


"I see. Well, I'll make a double rudder and increase the angle of attack. ......"



 Since changing the size of the rudder might upset the aerodynamic balance that we had confirmed, we decided to improve the rudder mainly in terms of the angle of attack.

Read at https://w w w . m t l r e a d e r.com


 The double rudder is more effective in preventing air separation and increasing the rudder angle by bending the rudder in two steps, whereas a normal rudder bends in only one step.

 This is also used in rudders for special vessels.

 Jin completed the modification in 15 minutes.



"Okay, now I need you to do it again."

"Yes, father. I'll take care of it."

 The rudder was flown again with the improved rudder, but there was no change in aerodynamics.

 Of course, the rudder was evaluated to work perfectly.

 After landing and lining up, Jin smiles and says to the three of them.

"Okay, Reiko, Soleil, and Luna. I'll call you three acrobats ......<>."

"Thank you for naming them. ...... father, can you name the plane too?"

"Yes, that too. How about ...... hmmm ............<>?"

"So, Luft 1,2,3..."



 Reiko's plane is Luft 1, Soleil's is Luft 2, and Luna's is Luft 3.

 Thus, Reiko and her three passengers' planes were completed, and the team was formed.

 There are still many more events to come.

 Still, with the support of Horai Island and the , Jin was sure that he would be able to handle them.
