A week later, a strange-looking vehicle slowly drove into the test explosion site.
It was the first crawler tractor manufactured by the Ministry of Industry of Neverwinter based on the complete set of blueprints and technical instructions provided by the Gray Pot Design Bureau. However, other than the chassis being the same, its appearance was completely different from that of the experimental product. The vehicle was surrounded by thick armor plates and looked like a moving square box at first glance.
After driving into the explosion zone, it stopped in front of the melted iron tower for about half an hour before turning around and driving south along the original road.
After driving for about five kilometers, a wheeled truck approached and picked up all the people on board, while the square box tractor was directly abandoned in the snow.
This group of people traveled all the way and returned to Neverwinter from the Great Snow Mountain the next day.
Upon receiving the news, Roland summoned them to the castle immediately.
"How was it? Did you encounter any accidents?"
"Please rest assured, Your Majesty. Everything went smoothly." Phyllis smiled and presented a sigil to him. "Summer quickly located the scene at that time. We stayed longer than expected."
"Because, because there was a specific time, it wasn't too difficult," Summer said shyly. "Compared to the other sisters, my ability to control my ability is considered poor …"
"Alright, don't be modest."
"It's, it's true …"
Roland took the sigil, but his expression was still solemn. He tilted his head to look at Momo beside him. "Sorry to trouble you."
"No, you're too kind, Your Majesty." Momo reached out to cover one of her eyes to avoid seeing His Majesty. At the same time, she displayed her ability. After a while, she put down her hand and bowed to Roland. "Everyone's number and color haven't changed significantly. It's basically the same as when we set off."
Only then did Roland let out a sigh of relief. He smiled and said, "Thank you for your hard work."
"You too," the witches replied in unison.
"Meals have been prepared in the reception hall. Chaos Drinks are available in unlimited quantities. Please fill your stomachs first." Roland looked at the joyful faces of the witches and shook his head with a smile. As for the Taquila witches who participated in the operation, they were basically regulars in the Dream World, so there was no need for any additional rewards.
Using Summer's backtracking ability to observe the instantaneous changes when the weapon was in action had always been the most reliable improvement method of the Engineering Department. By adjusting the backtracking speed, he could clearly understand the state of the target at every moment. Most of the problems and loopholes could be seen at a glance.
However, as mentioned before, the Glory of the Sun was different from other weapons, especially the dirty bomb that had yet to fully activate. There would be a lot of materials that emitted fatal radiation left in the area. If one were to enter rashly, they would undoubtedly suffer from a large amount of radiation damage.
For this reason, Roland did not hesitate to put the first tractor prototype into the project and modified it into a radiation-proof vehicle. Its left, right, rear, and bottom were wrapped with multiple layers of lead plates, sandwiched in the middle with gold foil and beryllium sheets. The overall thickness was up to ten centimeters, making it highly shielded against photons, electrons, and neutron jets. Only the steam engine powered by the Magic Cube could handle the structural weight of the comprehensive protection.
In addition, the car was equipped with oxygen and was almost completely isolated from the outside world, preventing the risk of radioactive dust entering the car through the ventilation channel. In order to observe the scene of the explosion, a huge lead-containing glass was installed in front of the car. The thickness of the glass was an astonishing 30 centimeters.
Considering that entering and exiting the Explosion Test Field might cause contaminants to stick to the tracks and armor, he specifically requested that once the personnel were sent out of the most dangerous core area, they should immediately change vehicles and abandon the former in the snow.
It could be said that Roland had used all the safety measures he could think of, but even so, it was still difficult for him to relax.
Fortunately, the final result showed that the observation operation was a complete success.
After getting the first-hand information from the crime scene, Roland immediately started researching with Anna and Celine.
…
Using the Sigil of Time to replay the scene that had been slowed down hundreds of times, the flaws of the No.1 Principle Device gradually surfaced.
"Our explosives are too weak," Anna said in a low voice.
"I can also see that the impact of the explosion didn't seem to be transmitted to the gun barrel." Celine nodded her main tentacle. "Can we use batch detonation to solve this problem? "
"I'm afraid there's not much hope in a short time." Roland rubbed his tired eyes. After watching the explosion live for two days in a row, he felt that the whole world was only left with blue and white colors.
Although he had expected the problem of explosives, he did not expect it to be so obvious.
Currently, Neverwinter had been mass-producing double-base smokeless gunpowder. Although it was not as powerful as RDX and other high explosives in terms of energy and explosive speed, it was enough for the army. Even if it was not powerful enough, it could be made up with quantity. However, when it was put into the principle device, the problem was revealed.
More than a thousand kilograms of explosives was definitely not a point on the blueprint. When stacked, it was as big as a safe. In order to transmit the explosive energy to the uranium, Roland specially made a funnel-like lens, hoping to concentrate the impact force as much as possible.
There was no problem with this idea, but before the detonation reached this step, there was already a problem. Because the total volume of the explosives was too large, and every point was detonated at the same time, the shock waves produced by the explosives in front and behind offset each other. This could be clearly seen from the slow-motion playback. The colliding shock waves caused the entire steel lens and even the outer shell to be severely deformed, which meant that a large amount of energy acted on the outside of the 'gun barrel'. Naturally, the energy used to move the uranium was much less.
Then, there was a chain reaction.
The lack of pressure in the gun barrel caused the fission to stop quickly. Most of the uranium was vaporized at high temperature, which indirectly weakened the effect of the neutron source.
"We can only find another way," Roland said with his hands spread out. Without electronic explosion control technology, it was almost impossible to ignite all the explosives in a thousandth of a second and cause the shock waves to overlap. Even if they replaced it with high explosives, it would only improve but not eliminate this problem.
He could ask the Ministry of Chemical Industry to try to develop low-speed explosives and place them in front of the lens to minimize the impact between the explosives as much as possible. However, this process would probably require a lot of experiments, and it was hard to say whether it would succeed or not. Now, the most reliable way was obviously to make up for the shortcomings of the detonation technology through the configuration design.
"It seems that I have to work overtime tonight," he said weakly as he stretched.
"I'll be with you," Anna said with a smile. "How about a Blackfire massage as a reward?"
"I suddenly feel full of energy." Roland was refreshed. "Is there any other reward?"
"Like what?"
"Let me think... Oh, how about the one I mentioned last time..."
Is this also the knowledge I learned from the Dream World...
