A week later, a strangely shaped vehicle slowly drove into the test explosion field.

It is the first tracked tractor assembled by the Winterfell Industry Department based on a complete set of drawings and technical guidance provided by the Ashtenbus Design Bureau.Except for the same chassis, its appearance and test products have been judged to two things.The vehicle was surrounded by thick armored plates, which at first glance looked like a moving square box.

After it entered the blasting area, it stayed in front of the melting tower for about half an hour, then turned the car and headed south along the original road.

About five kilometers away, a wheeled truck approached and picked up all the people in the car, while the box tractor was abandoned in the snow.

These people turned around all the way, and the next day they returned from the snow-capped mountains to the winter city.

Roland, who received the news, called them into the castle for the first time.

“There was no accident, right?”

"Rest assured, your majesty, all is well."pherys smiled and presented a letter to him, "Asha quickly positioned the picture at the time, and we stayed shorter than expected."

"Because, because there is a specific time point, so it is not difficult," Asha Piao said somewhat shyly, "than other sisters, my control of ability is poor..."

"Well, don't be humble."

“Yes, it is true...”

Roland took the seal, but the look was still serious.He looked up at Momo, "Please."

"No, you have spoken, your majesty."Momo reached out to cover one side of his eyes, lest he see his majesty, and at the same time exerted his powers.A moment later, she put down her hand and bowed to Roland, "the number and color of all have not changed significantly, and are basically the same as when they set out."

Only then did Roland relax and smile, "Work hard, you guys."

“You as well.”The witches echo.

"The living room is ready for meals, chaotic drinks are available in unlimited quantities, everyone fill their stomachs first."Looking at the happy people, he smiled and shook his head.As for the Tachira witch involved in the action, she is basically a frequent visitor to the dream world, and there is no need to give any additional rewards.

Using Asha's backwardness ability to observe the instantaneous changes in the role of weapons at close range, has always been the most relied on by the engineering department to improve the means.By adjusting the backtracking speed, you can clearly understand the status change trend of the target at every moment, and most of the problems and leaks can be seen at a glance.

But as has been said before, the glow of the sun is different from other weapons, especially the dirty bombs that have not fully reacted.There will be a lot of radioactive substances left at the scene, and if it enters, it will undoubtedly be damaged by a huge amount of exposure.

To this end, Roland was willing to put the first crawler tractor prototype into it, and converted it into a radiation-proof vehicle - its left and right back and bottom plates are wrapped in multiple layers of lead plate, sandwiched in the middle of gold foil and beryllium, the overall thickness of up to ten centimeters, so that it has a higher shielding effect on photons, electrons and neutron jets.The structural weight of the comprehensive protection is only the power of the magic Cube power-driven steam engine.

In addition, the vehicle has its own oxygen inside, which is almost completely isolated from the outside world, avoiding the risk of radiation dust entering the car from the ventilation channel.In order to observe the scene when the explosion occurred, the front of the car is equipped with a huge lead glass, and the thickness of the body has reached a staggering 30 cm.

Considering that the entrance and exit test explosion site may cause the track and armor to be attached to the contaminated object, he also deliberately requested that the vehicle be replaced as soon as 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 can think of the security measures are used out, but even so, he is still difficult to let go.

Fortunately, the final results show that this observation operation is finally a complete success.

After getting the first-hand information at the scene, Roland immediately conducted research with Anna and Celine.

...

The use of time stamps repeatedly played at that time slowed down hundreds of times the backstage scene, the defects of the No. 1 principle device also gradually surfaced.

"Our explosives are too bad."Anna whispered.

"I also saw that the impact of the explosion did not seem to be successfully transmitted to the 'gun's", "Sierin point, "can you use batch detonation to improve this problem?""

"I'm afraid there's not much hope for a short time."Roland rubbed some sour eyes, and after two days of watching the explosion record of the scene, he felt that the whole world was only blue and white.

Although the problem of explosives was expected, he did not expect it to be so obvious.

Winterfell has been mass-produced are double-based smokeless gunpowder, although it is not as fierce as high-explosive drugs such as black sozojin in energy and explosion speed, but it is enough for the army.Even if the power is insufficient, it can be compensated with quantity.However, when placed in the principle device, the trouble is revealed.

More than a thousand kilograms of explosives is by no means a point in the design, it stacked up to have a safe so big, in order to make the explosion of energy to the uranium block, Roland also deliberately made a funnel-like lens, hoping to bring the impact as much as possible together.

There is no problem with the idea, but the detonation has not yet reached this point has occurred, because the total volume of the drug package is too large, and each point is detonated at the same time, so that the shock waves generated by the front and forth explosives cancel each other a lot - this can be clearly seen from the back and slow, the shock wave hitting each other makes the whole steel lens, and even the shell has undergone a drastic transformation, which means that there is a lot of energy acting outside the "gun", and the energy of the uranium block is naturally much less.

Then there’s the chain reaction.

Insufficient pressure in the load causes the fission to stop quickly, and most of the uranium is gasified at high temperatures, which also weakens the effect of the neutron source.

"You can only find another way."Roland nodded.Without electronic explosion control technology, it is almost impossible to excite all the explosives in one thousandth of a second, making the shock wave before and after.Even if it is replaced with high explosives, it will only improve and not eradicate this problem.

He could allow the chemical department to try to study low-speed 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, and whether it can be successfully said.Today, the most reliable approach is obviously to make up for the technical shortcomings of the detonation technology through the configuration design.

"I've got to work overtime again tonight."He reached out and said weakly.

“I will be with you.”Anna smiled, “How about rewarding a black fire massage?”

"Suddenly it felt full of energy," Roland's spirited, "is there any other reward?"

“Like what?”

“Let me think... right, how was that last time...”

This is also the knowledge learned from the dream world.

Celine used the Lord to cover her slightly hot face and quietly left the North Slope Laboratory.
