Chapter 1192 The Man Chasing the Wind

The neutron source can be understood as a fission catalyst. With the extra neutrons it provides, even uranium-235 below the critical mass can be split efficiently.

Theoretically, polonium and radium separated from uranium ore can be combined with beryllium to form a neutron source. There are no technical problems in this. It is purely based on the characteristic that beryllium releases a large number of neutrons when bombarded by alpha particles. It only takes effect if they are put together. All three are naturally occurring substances, and their feasibility is undoubtedly much higher than those man-made elements that are extremely difficult to maintain or require complex processes to produce.

As for Roland's final choice of polonium instead of radium, it was purely due to safety considerations - although the half-life of polonium-210 is short, it basically decays by alpha, and the yield of gamma photons is extremely low. In other words, as long as you don't eat it, it's almost as safe as uranium. Radium is different. Whether it is the radon gas produced by subsequent decay or the gamma photons emitted by itself, they are potential safety hazards that cannot be ignored. In order to avoid accidents during the experiment, the polonium-beryllium neutron source has become the most suitable choice.

In addition, beryllium also has the property of reflecting neutrons. If it is used as a shell, the efficiency of neutron utilization can be further increased. If both are used at the same time, and a sufficient amount of uranium 235 is added, even the simplest and most reliable gun-type structure can achieve good results.

Beryllium is widely found in emeralds. Such a distinctive mineral saves Akima the effort of traveling through mountains and rivers to find it. She only needs to spread the news through merchant channels and purchase it widely in the four kingdoms.

Roland is very clear about the level of technology in Neverwinter - the principle of radiant radiation is simple to say, but every 10% increase in utilization rate is a threshold, from 1% to more than 90%, which requires a lot of theoretical calculations and According to the test calibration, if the energy cannot be released with high efficiency, it will be impossible to miniaturize the weapon, and the weapons-grade uranium that was finally accumulated will be wasted. Without Lucia, the loss of refining alone would be an insurmountable peak.

But similarly, if the loss is affordable or the loss is not considered, hand-made nuclear bombs are not just a joke. The technical thresholds vary widely, but the principle remains the same. Thanks to the inherent advantages of mass-energy conversion over chemical gunpowder, even if only 1% of uranium participates in fission, its power is enough to turn the tide of the war.

In the face of this life and death battle that determines the fate of the ethnic group, he will do his best.

What's more, isn't it also a kind of romance to steal divine fire and bring humans closer to the sun in such a barbaric era?

As long as there is a chance, he is willing to give it a try.

"Very good, just keep it like this," Roland patted Lucia's head. "When all the lead cabinets are filled, the formal experiment can begin."

"Yes, Your Majesty!" Lucia said enthusiastically.

*********************

At the same time, Neverwinter City, Sky Knight Academy.

This equally huge area, located to the west of the new institute, was quiet - today was a day off for students, and most people left the campus early to enjoy the time spent with their families, but Goode was an exception.

"Go up, press the pole!"

"Crosswind, roll!"

He sat on the simulated bridge, setting the wind direction for himself, and responding according to the regulations in the "Flight Manual". The wooden poles made a squeaking sound, like an old and disrepaired watercraft. car. The temperature in the training room was quite stuffy. After practicing for a long time, his back was soaked with sweat, and beads of sweat dripped from his chin from time to time, spreading on the simple "dashboard".

It wasn't until the handle slipped that Goode stopped, leaned on the chair and took a deep breath.

After nearly half a year of study, he was no longer the ignorant layman he was at the beginning. Not only did he memorize the "Flight Manual" written by Her Royal Highness the Princess, but all the basic operations were imprinted in his mind. From being in a hurry when I first boarded the bridge, I can now operate according to commands with my eyes closed. If you give yourself an order, you don't even need to say it. Just a thought, and your body will respond immediately.

But can this make you fly?

No matter how hard he imagined it, he could not picture the scene of facing the wind in his mind. "Capture the direction and size of the wind, feel the posture and vibration of the body, and then apply operating force coordinated with it." These were the original words in the manual, but he had no idea what it felt like. Whether he pulled it gently halfway or to the end, the driver's console would not give him any feedback. As for the "instrument panel" drawn with ink lines, it was more like laughing at his efforts.

The more proficient he became, the more frustrated Good became.

Just when he was a little upset, the door of the training room was suddenly pushed open with a creak.

"You are indeed here—"

"Well, my guess is correct, right?"

Good turned around and looked at the two people who walked into the room with a little surprise - they were Finkin and Heinz from the same team, "How do you..."

"Don't you use your vacation to have fun?" Finkin whistled, "Because the fun is in the academy."

"As for you, it's okay if you don't have a family. Don't you obviously have a lovely sister?" Heinz stepped forward and grabbed his neck, "She also asked me to tell you to stop being tired, tsk tsk... so good."

Gude's expression suddenly tightened, "Wait, you two went to where I live?"

"Nonsense, otherwise where would we find you?" Finkin raised an eyebrow at him, "Her name is Rachel, right? How about introducing her to us?"

"Don't even think about it," Goode glared back.

"Do you think our conditions are not enough?" Finkin said unconvinced, "At least I still have a formal residence in Chishuihe Community!"

Good was silent for a moment, and finally shook his head helplessly and said, "It has nothing to do with you, but my sister... Rachel's own problem. You don't want to be with her."

"Why? I think she's pretty good," Heinz asked confused.

"Tell me about it?" Finkin also looked curious.

"Stop asking this," Good said angrily, "Tell me something else - what did you mean by the fun you mentioned before?"

Finkin did not continue to pester. He lowered his voice and said mysteriously, "Do you want to try a real airplane?"

Good couldn't help being stunned, "What did you say?"

"I saw it when I climbed the fence a few days ago," Finkin said with a slightly proud smile. "Several new airplanes have been transported into the airport warehouse. Although they are covered with cloth, judging from the size, they are all the same as the princess. The Unicorn flown by His Highness is similar. In other words, that is the plane prepared for us!"

"How many days ago? Why didn't you say anything then?"

"I'm not worried that you might get too excited and leak the news." He shrugged, "And today is a holiday. There are only a few people in the academy. It's a chance to sneak in and see his true face!"

"You are crazy!" Gude said in disbelief, "We cannot enter the aviation field at will without permission!"

"Those soldiers won't let you in, okay." Finkin rolled his eyes at him, "Of course we have to take another way, and it doesn't pass through the flying field."

"But……"

"We are just taking a look," Heinz also helped. "You should be able to feel it. Her Highness Tilly has been smiling a lot less recently, and her training has become much stricter. If this continues, we may have to wait. It will take a month or two to actually touch it. Compared to this simple wooden platform, don't you want to see in advance what the plane we are going to fly looks like?"

"If you don't want to go, we will take a step ahead." Finkin said with a frown.

Good hesitated for a long time, and the boring squeaking sound of the wooden pole when he was fiddling echoed in his mind, as well as the confusion of not feeling any progress no matter how hard he practiced. Finally, he bit his lip, nodded and said, "I'll go and lead the way. Bar."
