Chapter 3317

The bomb was made temporarily, so it was in a hurry, so many things were replaced, such as the air pressure sensor. The real air pressure sensor is actually quite a complicated thing, but the device used in this device is actually not a pressure sensor at all.

This so-called air pressure sensor is actually a syringe like syringe, but its inside is vacuum. Once the internal pressure of the oil cylinder is released rapidly, the external pressure of the oil cylinder will not be affected. There are two copper plates at the bottom of the vacuum cylinder. There is a gap between them, so that there is no connection between them, that is, there is no electricity. This state means that the surrounding environment is still a vacuum. The bottom of the piston is covered with a copper sheet. Once the external air pressure recovers, the piston will be pressed into the bottom of the air cylinder. Then the copper plate contacts the two copper contacts at the bottom of the cylinder at the same time, and the circuit is connected. And once the circuit is connected, the air pressure is restored, and the bomb detonates.

This design is very simple, but it is quite deadly, because the speed of air pressure recovery is very fast, and the piston is super sensitive. Therefore, as long as ordinary people open the oil tank, it will inevitably cause an explosion. But now frost and snow have sealed the top of the tank, so even if the lid is opened, air will still not be able to enter the tank, so that the air pressure trigger will not start. As for dismantling it This is the simplest. Just pull out the piston.

Without the barometer, frost and snow scanned again anxiously to confirm that there was only one barometer, and then the ice layer on the surface was removed.

After the air pressure recovered, the bomb did not explode because the barometer was no longer working. Now the shell of the bomb has basically failed, we are confident and bold to cut the whole oil tank wall directly, so that the bomb is completely exposed in front of us.

Intuitively, the structure of the bomb is quite complex, and there are very precise pipes outside, and these pipes are the main design that can't remove the wires.

The other side actually jammed the bomb into a set of pipes. In addition to the barometer outside, the inside of the pipe is filled with something similar to grease. It doesn't conduct electricity, and it can shield electromagnetic fields and dissipate heat.

All the lines used by the bomb are sealed in this pipe, and the grease filling inside the pipe is the second insurance, because once we open the pipe, the oil pressure inside the pipe will disappear. Without oil pressure, the bomb will be immediately detonated by a trigger device. Therefore, the pipeline filled with grease is also a kind of anti disassembly design.

Of course, we don't want to dismantle the pipeline, but we want to attack the bomb directly.

Because the magnetic field shielding device has failed, it is impossible to completely shield our electromagnetic induction ability by relying on the shielding of grease itself. Further scanning of the interior confirmed that the bomb's internal detonators were ultimately connected to four batteries.

Modern bombs, as long as they are not ignited on the spot, must be electrically initiated. In fact, modern high-end explosives are quite safe. Many military explosives will not be detonated even if they are thrown into the fire. It is necessary to use an arc generated by a strong current to detonate this kind of bomb at a high temperature of several thousand degrees in an instant.

This kind of design has many advantages, the biggest advantage is safety, it won't explode without any reason. However, their disadvantage is very uniform, that is, the need for electric current to detonate.

The electric current needed to detonate a bomb is not too much. A button battery the size of a dollar coin is enough to detonate the primary explosive. Then the series initiation method of explosive detonating explosive can detonate any explosive of any specification.

The bomb's internal structure is more complex, so it uses four sets of batteries, one of which is the main battery, which is directly a lead-acid vehicle battery. The other three batteries are all the same lithium batteries, which seem to have been removed from some kind of remote control. After all, this kind of battery with positive and negative electrodes on one side belongs to special battery, which is not very common.

The solution we came up with to solve this bomb is on these four batteries.

There are too many protection designs on the bomb. If we crack them one by one, it will take too long. And the surrounding enemies are not in a daze, they have begun to attack us. It's just because the electromagnetic barrier composed of Jingjing and XiaoLongNu protects us, so the bullets can't threaten us for the time being. However, such a hard to carry each other's attack can not last long, after all, those outside are not miscellaneous soldiers, their equipment is very good.

Because we are in a hurry, we need a simple and direct way to solve the bomb, so the final solution we think of is stealing electricity.

No matter how complicated the bomb is, it must need electric current to start the bomb. Even for a nuclear bomb, the initial detonation requires electricity. There is no mechanical bomb, but at least this is not. What we need to do is to drain all the batteries that can be discharged inside the device. As long as the battery is dead, no matter how many initiating devices we trigger, the bomb will not detonate, because there is no electric current to detonate the bomb.

The reason why we plan to steal electricity rather than cut short the wire is mainly because there is oil pressure in the series pipe, so we can't react faster than the current when we cut it down. Therefore, before cutting off the current, it will inevitably lead to the explosion of the bomb. In addition, the bomb has several lines. If it cannot be cut off at the same time, it can not guarantee that the bomb will not detonate. Even though the speed of our dragon clan is very fast, and the behavior can be synchronized, this synchronization is only superficial synchronization, and there must be some gaps in the details. These wires must be cut off synchronously to ensure that the bomb will not be detonated, and the error interval between them should not be less than the time that the current in the circuit inside the bomb runs through all circuits. The speed of electricity is the same as the speed of light. The total length of the circuit in the bomb will not exceed 100 meters. Imagine how long it will take for the current to complete this distance. Obviously, we can't cut all the lines at the same time in such a time, so this method is not feasible.You can cut down the power, but you can't steal the wires.

There is no voltage detection system in the bomb. Therefore, if we discharge the battery, the bomb itself will not react in the process of gradual drop in voltage. When the voltage drops to a stable voltage output of the regulated capacitor, the detonating device of the bomb may be connected to the initiation circuit, but the remaining power in the battery will be in any case It's not enough to detonate a bomb. In this way, the bomb is completely abandoned.
