"The speed of the plane when it touches the ground cannot be reduced to zero, so there will be an impact on the plane and the crew," he said.

"Hopefully they'll take it softly. ...... Can't we do something with common wind magic?"

"Yes. How about using toward the ground just before it hits the ground?

Would that work as an air cushion?

"What do you think, Jin-sama?"

 Jin thought it was not so wrong to ask me if the idea was right or wrong here, and said his thoughts.

"I don't think it's a bad idea. is the same magic we use for the engine, so it's not that special."

"Yes, it is!"

"If you are interested in ......, I would like to experiment with it."

"Then, think about how to conduct the experiment. If possible, it should not be something that can only be done on Horai Island.

"What do you mean?"

"Well, even if it's impossible to do it in Reuthert's house, I'd like to do it on <> or <>...... preferably in a workshop that's reasonably well equipped and can reproduce it if we take our time. I guess."

You mean a common method of experimentation.

"Yes, yes."

 Jin explained that it was meaningful to think about such an experimental method in order to leave a signpost for those who would follow in his footsteps.

 Understanding this, the two men pooled their wisdom and began to think of ways to conduct the experiment.

"How about we build a tower ...... and drop the experimental machine from it, and use a before it touches the ground?"

"Why don't we drop them from the bridge instead of building a tower?"

"Oh, in that case, there is water below, so the experimental machine will be less damaged.

 These are all quite useful opinions.

"Maybe we should start with a one-half to one-fifth scale model.

"Okay, but how do you know when to activate the <>?"

"It's an experiment, so I guess we could start it wired."

"I guess so. ......"



 Observer Jin thinks that the two of them are a good match after all.

 In the end, it was decided to <><< from the bridge>>.

 After repeating these tests and acquiring data, they came up with the idea of using an experimental plane of similar size to the actual model and dropping it from a high altitude in an <>.

"Yes, that could be done at least with <>.



 Jin thought that the necessary data could then be made available to the public.

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



 Then, even if the workshop could not conduct large-scale experiments, it would be possible to mount an < based on the data.

 Alternatively, <> could be provided by <> and other major workshops.

 We should not use this in the first place, because it should be very rare .......

 We will try to experiment with it first.

 Discussion is suspended.

 Jin decided that Goh and Rubina must be getting bored by now.

 And it seems that he was right.

"Well, I made a gauze that is almost the same size as the Nile VIII, is that okay?

"Yes, it's good."

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



 Rubina made an experimental plane for us. This time, since it was on Hourai Island, the size was 1/1 for the experiment.



"Jin-sama, how about this?

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





 Then, I had Goh prepare a magic tool that generates <>.

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



 Combining the two, we conduct an experiment in place of <>.



 This time, we will suspend the craft from <>, descend at a speed of 20 km/h, and use <> just before the craft touches the ground.

 A G-meter was also attached to the cockpit to record acceleration.



"Free fall is a bit tough, isn't it?"

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





 If we ignore air resistance, the fall speed will reach 20 km/h at 1G of gravity after 0.56 7 seconds.

 It would be impossible for a human being to manage.

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



 Therefore, <> is also impossible.



"We'll have to use a crane and lower it down at 20 kilometers per hour, won't we?"

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



"That's right."



 Now that we have an alternative plan, we can start the experiment.

 < using a rope made of highly flexible . The length of the rope is 100 meters.

 The machine is then lifted up for 50 meters, and after standing still, descends at a speed of 20 km/h. The machine is then suspended by a rope made of flexible .

 The magic tools on the experimental machine will be activated by you only this time.

 The reason is that he can turn on the magic tools by using <>.

 Jin, who was looking at the equipment, was thinking that it might be wired if it is for general use.

 As Jin was thinking about this, he was brought back to himself by the sound of the aircraft suddenly braking due to a < that occurred.

"Oops."

 About 100 meters away, the experimental plane has landed safely.

 Goh and Rubina are just now running to it.

 Jin also joined the experimental plane a little later.



"Well, it looks pretty good.

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


Nothing is broken.



 Goh and Rubina are satisfied after examining the machine.

"What about the G-meter?"

"Oh, yes, yes.

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


"The value is ......3.1G!



 Jin pointed out, and the two checked the G-meter in the cockpit and shouted.

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




"Well, I guess that's about right."


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


 The G-force meter was a little higher than that, but it would be more than twice that if they hit the ground, depending on whether they hit a rock or a soil.



"The point is that the acceleration value is how long it takes for a 20 km/h vehicle to stop."

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


"That's right. ......"



 Since the timing of the < would probably change somewhat, we continued the experiment.

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


 As a result, the lowest value of 2.8G was obtained when using <> at an altitude of 3 meters, which again slightly increased the safety.

 After the experiment was over, we had another discussion in the laboratory.

"There is an idea to use a flap from the anterior edge in addition to the Fowler flap," he said.

"That would complicate the structure.

I can make a one-off without any problems.

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


"Yes, that's true."



 If we put too many complicated mechanisms or special technologies in the aircraft, it will not be suitable for the general public, so we need to keep it in moderation.

"If possible, I'd like it if we could glide down close to the ground and use an air cushion to make an emergency landing.


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


 Goh said with a sigh.



"Yes, that's right. Then, wouldn't it be better to make the main wings a little bigger?"

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


"Well, that would reduce the maximum speed and change the performance of the plane.



 Rubina countered Jin's suggestion.

"That's right. But safety is the highest priority, isn't it?"

"Yes,......, that's right,......."

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


"Then let's try to increase speed and mobility while ensuring safety."

"Yes,......, that's right,......."

"You're going to fly with Mertzsche on board, right?"

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


"Yes!



 Rubina and Goh seemed to be convinced by Jin's persuasion.

 Once again, the production time begins. .......
