A week later, a strangely shaped vehicle slowly drove into the test site.
It is the first crawler tractor manufactured and assembled by the Neverwinter City Industry Department according to the full set of drawings and technical guidance provided by the Ashpot Design Bureau. Except that the chassis is the same, its appearance is completely different from that of the test product. The vehicle is surrounded by thick armor plates on all sides, which at first glance looks like a moving square box.
After it entered the center of the explosion, it stayed in front of the molten iron tower for about half an hour, then turned around and drove south along the same road.
After driving for about five kilometers, a wheeled truck approached and picked up all the people in the car, while the square box tractor was directly abandoned in the snow.
This group of people went all the way and returned to Neverwinter from Daxue Mountain the next day.
And Roland, who got the news, immediately called them into the castle.
"How is it, did you encounter any accidents?"
"Please rest assured, Your Majesty, everything went smoothly." Phyllis smiled and presented a talisman in front of him, "A-Xia quickly located the scene at that time, and our stay was shorter than expected."
"Because, because there is a specific time point, it's not too difficult," A-Xia said shyly, "Compared to other sisters, my ability to control my abilities is poor..."
"Okay, don't be humble."
"Yes, it's true..."
Roland took the talisman, but his expression remained serious. He tilted his head to look at Momo beside him, "Excuse me."
"No, your words are serious, Your Majesty." Momo stretched out his hand to cover one of his eyes, so as not to see His Majesty the King, and at the same time showed his abilities. After a while, she put down her hand and bowed to Roland, "Everyone's numbers and colors have not changed significantly, and they are basically the same as when they set off."
It was only then that Roland breathed a sigh of relief and said with a smile, "Thank you for your hard work."
"You too." The witches responded in unison.
"Meals have been prepared in the parlour, and Chaos drinks are available in unlimited quantities. Let's fill your stomach first." Looking at the delighted crowd, he shook his head with a smile. As for the Takira witches who participated in the action, they were basically regulars in the dream world, and there was no need to give any additional rewards.
Using A-Xia's retrospective ability to observe the instantaneous changes of the weapon's action at close range has always been the most relied upon improvement method for the Engineering Department. By adjusting the backtracking speed, you can clearly understand the status change trend of the target object at every moment, and most problems and mistakes can be seen at a glance.
But as said before, Sunlight is different from other weapons, especially dirty bombs that don't fully react. There will be many substances that emit deadly radiation left on the site. If you enter the site rashly, you will undoubtedly suffer a huge amount of radiation damage.
To this end, Roland did not hesitate to put the first crawler tractor prototype into it, and converted it into a radiation-proof vehicle - its left and right rear sides and the bottom plate were wrapped with multi-layer lead plates, with gold foil and beryllium sheets in the middle, and the overall thickness As much as ten centimeters, it has a high shielding effect on photons, electrons and neutron jets. And the structural weight brought by the comprehensive protection can only be carried by the steam engine driven by the power of the Rubik's Cube.
In addition, the car has its own oxygen inside, which is almost completely isolated from the outside world, avoiding the risk of radioactive dust entering the car from the ventilation channel. In order to observe the scene of the explosion, a huge leaded glass was installed in front of the car body, and the thickness reached an astonishing 30 cm.
Considering that entering and leaving the test site may cause contamination to the tracks and armor, he also specifically requested that the vehicle be replaced immediately once the personnel were sent out of the most dangerous core area, and the former was directly abandoned in the snow.
It can be said that Roland has used all the safety measures he can think of, but even so, he still finds it difficult to relax.
Fortunately, the final result showed that this observation operation was finally a complete success.
After getting the first-hand information on the scene, Roland immediately conducted research with Anna and Celine.
…
Using the time symbol to repeatedly play back the scene that was slowed down hundreds of times at that time, the defects of the No. 1 principle device gradually surfaced.
"Our explosive performance is too poor." Anna whispered.
"I can also see that the impact of the explosion does not seem to be smoothly transmitted to the 'bore of the gun'," Celine nodded, "Can you use batch detonation to improve this problem?"
"I'm afraid I don't have much hope in the short term." Roland rubbed his sore eyes. After two days of watching the actual explosion at the scene, he felt that the whole world was only blue and white.
Although he had expected the problem of explosives, he did not expect it to be so obvious.
Neverwinter City has been mass-producing double-base smokeless gunpowder. Although it is not as violent as high explosives such as Hexokin in terms of energy and detonation speed, it is enough for the army. Even if the power is lacking, it can be made up for with numbers. But put it in the principle device, and the trouble is revealed.
More than 1,000 kilograms of explosives are by no means a point on the design diagram. It is the size of a safe when stacked. In order to transmit the explosive energy to the uranium block, Roland also specially made a funnel-like lens, hoping to The impact is as concentrated as possible.
There is no problem with this idea, but the situation has already occurred before the detonation has reached this step. Because the total volume of the charge bag is too large, each point is detonated at the same time, so that the shock waves generated by the front and rear explosives cancel each other out a lot - this It can be clearly seen from the retrospective slow playback that the shock waves colliding with each other caused the entire steel lens and even the outer shell to undergo severe deformation, which means that a large amount of energy acts outside the 'bore of the gun' and pushes the uranium. The energy of the block is naturally much less.
What follows is a chain reaction.
Insufficient pressure in the chamber causes the fission to stop quickly, and most of the uranium is gasified by high temperature, which also weakens the effect of the neutron source in disguise.
"We can only find a way through other means." Roland spread his hands. If there is no electronically controlled explosion technology, it is almost impossible to excite all the explosives in sequence within a thousandth of a second, so that the front and rear shock waves overlap. Even switching to high explosives will only improve but not eradicate this problem.
He can ask the Ministry of Chemical Industry to try to study low-velocity explosives and place them in front of the lens to minimize the interaction between the explosives, but this process may require a lot of experiments to deploy, whether it can be successful or not. The most reliable way to do it today is obviously to make up for the deficiencies in detonation technology through configuration design.
"It looks like I have to work overtime again tonight." He stretched and said weakly.
"I'll accompany you." Anna smiled, "How about rewarding a black fire massage?"
"Suddenly feeling full of energy," Roland refreshed, "Is there any other reward?"
"Like which?"
"Let me think... by the way, how about the one I mentioned last time..."
Is this also the knowledge learned from the dream world...
Celine covered her slightly hot face with her main whiskers and quietly left the North Slope Laboratory.
