To be honest, after receiving Rebecca's revelation, Gawain instantly realized that this little "repulsion trick" was simply the biggest surprise that the world had given him: simple, low consumption, stable, and effective. not bad.
Anyone who has contact with magic organs will be familiar with this basic magic: whether it is a magic door that opens automatically or something else, as long as there is a structure in the mechanism that needs to be pushed, it will definitely There will be a "repulsion trick", and how much power can it output? As a spell, its power depends entirely on how much magic power you can provide and the performance of the magic material itself. In Gawain's opinion, its conversion efficiency is extremely high: the door of the mountain treasure house is made of heavy purple steel. Cast, a single door weighs several tons, and the ancient mechanism that controls the opening and closing of the door can operate easily with almost no mechanical optimization. Of course, this is because the ancient Gondor Empire has black technology, and the magic crystal they purified The performance is terrible, but the contemporary "bad products" are not bad either. Magic traps that can push boulders all over the ground are not too rare!
As for all these magic mechanisms, their use of the repulsion magic circle is actually quite primitive and clumsy - it is the route of flying bricks with great force. In the spirit of using force to produce miracles, the repulsion magic circle is used to push hard, almost. He never considered using things like lever gears for optimization...
So Gawain has high expectations for the magic engine. He believes that even if he uses cheap materials to build the engine, then The power things can provide will also be incredible.
After the "piston version" of the magic engine was discussed, he thought of further using the repulsion array without waiting for Rebecca and Hetty to complete the transformation of the drawings and detailed demonstrations. , extended to a structure similar to an electric motor.
A motor composed of a stator and a rotor naturally has additional advantages: its structure is relatively simple, and the failure rate is greatly reduced; when it starts, the "repulsion point" on the rotor can directly operate at full load, and the starting torque It is very large, unlike the piston engine which lacks starting torque and needs to wait for the speed to increase before the torque can reach the maximum; its volume can be compressed to a very small size, and it has a higher volume efficiency ratio when it also uses the magic network to supply energy. ; Thanks to the particularity of magic technology, the "rotor-type magic energy engine" does not require brushes or a "toggle device" for frequently switching rune triggers, which not only reduces the failure rate but also improves It extends the overall life of the machine (because there are very few wear parts), which is quite cost-effective...
But it also has obvious shortcomings - regardless of the advantages and disadvantages of electric motors and internal combustion engines on the earth, just from "this Starting from the technology of "World", the rotor-type magic energy engine in Gawain's conception needs to have a large number of "repulsion points" distributed throughout the shell to ensure the balance and continuity of the afterburning process, and placing so many independent magic arrays Together, it is necessary to ensure that they cannot interfere with each other, that the output is accurate and consistent, that the distance from the rotor is accurate, etc. In this way, the technical difficulty of the engine's mechanical structure is reduced, but it is improved in the formation.The difficulty in drawing, and the latter... The technical talents required are more difficult to cultivate. A little more complexity in this aspect will cause much greater trouble than a little more complexity in the mechanical aspect.
But no matter what, this idea is extremely tempting, and it is impossible for Gawain to give it up.
So he took a blank piece of paper from the side and quickly sketched a sketch under the curious gazes of Amber, Rebecca and Hetty.
A ring-shaped shell, an internal rotor with many inclined blades (repulsion objects), and many symmetrically distributed repulsion arrays on the shell...
Its structure is so simple .
"This is..." Hetty raised her eyebrows and spoke curiously and hesitantly.
Gao Wen put down his pen and said with a little excitement: "The second generation machine."
The three people present except him were stunned for a long time. After that, Amber looked at Gawain like a monster: "How did you get such a brain?"
"Don't insult my ancestors!" Rebecca immediately became angry when she heard this and copied it. After picking up the staff, she put the tip of the staff on Amber's forehead, but then she turned around and asked, "Ancestor, how did your brain grow?"
Gawain: "..."< /p>
It wasn’t until two seconds later that Rebecca realized what she was doing. She quickly put away her staff and apologized honestly: “I’m sorry, Ancestor, I was out of my mind again…”
” No, that's not the problem." The half-elf lady, who survived the crisis of being shot by an iron rod, was not at all at ease. She stared and continued to exclaim, "We haven't even finished discussing your first generation sketch here, and you actually The second generation was created easily? And it doesn’t look like it was born from a biological mother in terms of principle or structure... I’m afraid you have a lot of sketches waiting in your mind, right? ” p>
Gawain almost choked with a mouthful of saliva into his bronchus: Is this guy a coincidence?
“It’s just an immature idea.” He quickly stopped his expression that was about to collapse and looked at Hetty, who was thinking more carefully. “The principle is very simple. What do you think is feasible? "Like this?"
"It is indeed much simpler. Theoretically it is very feasible...but it may not be easy to do in practice." It's exactly the same as the article envisioned, "A large number of repulsive magic arrays are arranged together, and they are also arranged in this symmetrical and close arrangement. They are almost specially prepared for magical resonance. They will 100% interfere with each other. Whether they can move after being activated is a question."
"What if the diameter is enlarged so that the distance between each 'repulsion point' is also enlarged?"
"...The feasibility is still not high, I can understand you means that these repulsion points must be continuously 'relayed' in order to push the rotating part in the middle with maximum efficiency, so their distance is limited no matter how far they are. Rather than extending the distance, it is better to find a way to add a magic-forbidden structure between the magic circles. shield interference, but thisIn this case... the cost would probably be terrifying. ”
Gawain immediately twitched the corner of his mouth with toothache: Forbidden magic materials, even the cheapest ones are precious metals in magic materials. If they are really used in mass-produced machines, then even if he dies on the spot. Let people bury them, and Rebecca and Hetty can't afford it even if they collect tickets for people from all over the country to visit... What kind of ridiculous metaphor is this?
"Then do it when you have spare time? Let's study a prototype, which can be considered as a technical accumulation." Gao Wen sighed, "First of all, we need to get the piston prototype machine. Most of its parts can be hand-made by Hammer and his apprentices. It is relatively difficult. Part of the machine and the repulsion mechanism are handed over to the new rune craftsmen. Remember, don’t consider the cost of the first machine. As long as it can run safely and stably, we will succeed - and it doesn’t even matter if we sacrifice some performance on this basis. question. ”
Hetty and Rebecca left with a lot of drawings. Considering the administrative pressure on the former, Gawain gave Rebecca the main task of manufacturing the magic engine prototype, and Hetty Ti Ze still only provided some technical support, which once again made Rebecca extremely happy.
After they both left the tent, Gawain gathered up the remaining drawings and handed them over. He asked Betty, who was squatting on the ground nearby and practicing writing seriously with twigs: "Put them away. By the way, I asked the carpenter to make a small desk for you. It will be delivered to your tent in the evening. By the way, there is also a set of stationery and some white paper - save it. "
Betty took the sheepskin bag containing the drawings and was stunned for a moment, then showed a very happy expression, bowed hard and almost threw herself forward: "Thank you, sir~! That's so kind of you! ”
The little maid almost jumped away.
Gawain looked at the little maid’s jumping back with a smile on his face, and couldn’t help but smile and shake his head. He shook his head, and the look in Amber's eyes became strange: "I'm surprised, you are so busy all day long, and you still have time to take care of this silly girl like this... Could it be that this is your real hobby? Ugh - it's popular for guys like you to attack your own maid... Ouch, it hurts! "
Gawain pinched Amber's ears hard and said angrily: "What's the habit? I just like that child's hard work, eagerness to learn and progress, can't you keep your mind clean? "
Amber rubbed her ears and looked at Gawain angrily: "Don't you always say that I have a clean mind? "
Gawain: "...I mean your mind is completely blank and you have no knowledge or skills! ! ”
“Huh? Didn’t you praise me for a long time? ! "
Gawain glanced at this embarrassing half-elf and walked towards the tent door.
As expected, Amber couldn't restrain her curiosity and followed her: "What are you going to do? Want to eat something delicious secretly? Take me one! "
Gawain waited for Amber to catch up and then said casually: "Go and have a heart-to-heart talk with that big iron ball.It has been lying in the tent for so long, so it should be willing to say something to me. "
As soon as Amber heard this, he immediately lost interest: "Oh, then I won't go..."
Gawain fished it out easily, and then caught it in his arms again Wo was ready to take him away.
But this time he failed: Amber, who had been tortured once before, had already escaped into the shadows the moment he was caught, and Gawain felt his hand. As soon as the room was empty, the half-elf thief had already ran more than ten meters away.
"Go and talk to Qiu~" Amber shouted proudly from a distance, "I'll go have a meal with Betty." ~~"
Gawain glanced at this "nominal guard" who had his own way of doing things, waved his hand and turned to leave.
In front of the special tent in the south of the camp, Gawain asked the guard Regarding the metal ball: “What’s going on with that guy in the tent? "
"No," the conscientious soldier straightened up and replied, "We have been guarding here, and the ancient magic device stayed in the tent and had no intention of going out. ”
Ancient magic device, this is Gawain’s explanation to the soldiers who witnessed the metal ball. Now it seems that this explanation has been accepted by them.
After casually encouraging the soldiers who were standing guard carefully, Gawain stepped into the tent.
The metal ball was floating in the center of the tent, about half a meter above the ground, looking like a sci-fi fantasy. Suspension device.
But this sci-fi ball said nonchalantly: "Oh my god, I thought you just left me here and forgot about it!" There were only a group of dull-witted soldiers standing guard around. Either that annoying little old man came in, or that female human who liked to wear a red dress came over. They were both very boring. Let me tell you, if I, Qiu, didn’t value my commitment, I would have left early this morning..."
Gaowen ignored Qiu’s nagging and went straight to the latter: "I’m here to talk to you today. Let's chat, let's confirm one thing first - you are probably not from here... are you? ”
