The two stood on the top of a sand dune a thousand meters away. Cheng Chao, among them, held an AWP sniper rifle in his hand, aiming at a dead tree trunk a thousand meters away.
"It is now full southeast wind, wind force 3, wind speed 6.5 meters per second, minute angle 7."
Chen Chen reminded him at the side, "After you fire, don't look at the results. Immediately turn your back and hide behind the sand dunes. Do you understand?"
"OK."
Although he didn't understand what Chen Chen meant, Cheng Chao still nodded without any objection.
Chen Chen put on a pair of sunglasses, with only his head exposed on the top of the dune, and was ready to escape, "Okay, you can shoot!"
Chen Chen's performance made Cheng Chao a little panicked. He simply knelt on the top of the sand dune and aimed firmly at the pendant a thousand meters away.
boom!
Following the sound of a gunshot, Cheng Chao immediately turned around and jumped off the sand dune without even looking, imitating Chen Chen's actions and lying down to protect his head.
Then, the two of them waited for more than ten seconds with their eyes wide open.
Emmmmm…
Nothing happened.
Cheng Chao smiled sheepishly, then returned to the sand dune and started a new round of shooting.
boom!
There was another gunshot.
In order to prevent his eyes from blinking, Cheng Chao first turned his head and glanced into the distance with his peripheral vision. When he saw that he still missed, he continued with the third round of shooting...
boom!
boom!
boom!
…
This lasted for five minutes, and three magazines were shot out just by the bullet range. Just when he was a little numb, a white light suddenly flashed in front of his eyes.
Suddenly, Cheng Chao understood something. He turned his head without thinking and jumped off the sand dune immediately!
Behind the dunes, Chen Chen only felt a flash before his eyes. The sky suddenly became brighter, and then three seconds later, a deafening sound came!
boom!
With the deafening sound, Chen Chen felt an almost exhausted shock wave coming, and the huge impact blew away the sand on the top of the dune!
That was the shock wave formed after the powerful explosive exploded!
Suddenly, the two of them were splashed with yellow sand and were almost buried in it.
This shock wave came and went quickly. After a few seconds, Chen Chen lifted his head from the sand, took off his glasses and shook his head vigorously, then opened his mouth and poured water into his ears.
The huge sound made both of them tinnitus.
Not only that, when Chen Chen looked into the sky, he even found a regular circular pattern above his head. Threads of clouds gathered in the sky and circled the city. The center was empty and extremely eye-catching.
This power...
Chen Chen suddenly felt bad. This thing really shouldn't be used as an energy storage device, but should be used as a bomb. And he hung this bomb around his neck for half a year.
After climbing over the sand dunes again, Chen Chen saw that the dead tree where the "Galaxy Pendant" was hung was long gone. Not only was the tree gone, but the land was also gone.
Only a huge crater with a depth of tens of meters and a radius of one hundred meters appeared on the surface.
"Only about a hundred meters?"
Seeing this scene, Chen Chen couldn't help but frown.
The scope of the deep pit was only one-fifth of the expected size. In other words, a sniper bullet only excited about 4-5 tons of TNT energy in the 'Galaxy Pendant'.
That is one-fifth of the internal energy.
AWP uses 12.7×99mm rifle bullets. The known warhead mass is 46.01 grams, the initial velocity is 850m per second, the terminal velocity is 0, and the action time of the warhead hitting the 'Galaxy' is about 0.01 seconds. According to The momentum theorem can be obtained as (N-mg)t=0-(-mv), N=mg+mvt.
In other words, when the bullet hits the "galaxy pendant", the force acting on the galaxy pendant is about 4000N. If it is divided by the contact area, the pressure can be easily calculated.
And it is these forces and pressures that inspire the power of the four tons of TNT explosives inside the galaxy pendant.
Well, it’s very intuitive.
Thinking of this, Chen Chen walked towards the pit and finally found the undamaged galaxy pendant in the pit.
Sure enough, even if the energy is stimulated, they can still remain unscathed. Although I don't know how the aliens in the movie stimulate the internal energy, it is obvious that impact stimulation is also a method of stimulation.
Thinking of this, Chen Chen already knew what he was going to do next.
As long as you find someone to make an electrical device that can charge the galaxy pendant, you can charge it 24 hours a day. Even if you have to take the USB flash drive away with something in the future, you can use the galaxy pendant instead of the USB flash drive, so that no electricity will be generated. waste on.
As for absorbing electricity and wanting to stimulate it, that's even simpler.
Chen Chen only needed to refer to the car engine and first install and fix the galaxy pendant in the combustion chamber. Then when the machine started, the piston would automatically hit the pendant.
With each impact, energy will be excited. This energy will push the piston back, and at the same time, the connecting rod of the piston will again give the force for the next impact due to inertia...
Infinite loop.
The only difference between this kind of engine and a car engine is that it replaces fuel excitation with the way that the piston strikes the pendant to excite energy, and gets rid of the fuel supply.
And by adjusting the force with which the piston hits the pendant, the amount of energy the pendant excites can also be controlled.
Not only that, Chen Chen also thought of another use for the galaxy pendant.
If only a small amount of energy is retained in the pendant and installed on the detonating device, doesn't it mean that only a small piece of explosive is needed to detonate all the energy in it
This is undoubtedly a very powerful bomb. Just like just now, the force of only 4000N can reach ten times the power of the Tomahawk missile. It is simply a must-have prop for killing people, stealing goods, and traveling at home.
The most important thing is that this prop only weighs 20 grams, and I can take in many of them for backup...
Thinking of this, Chen Chen quickly returned to the research center and began to draw the design drawing of the engine.
In order to stimulate as much energy as possible at one time, Chen Chen designed the engine into a multi-cylinder form, with each cylinder reaching a diameter of two meters. He replaced the fuel chamber with an impact chamber and eliminated the air intake and fuel injection ports. , even the spark plug was completely abandoned.
After drawing the design, Chen Chen called Qian Wenhuan and asked him to contact Germany to see which engine manufacturer could manufacture the engine he designed.
As for the leakage problem, there is no need to worry, as long as Chen Chen claims it is a handicraft and a hobby, after all, in the eyes of those people, this kind of engine is simply unknown and has no possibility of use.
They didn't know the existence of the galaxy pendant, let alone think that there was a material in the world that could stimulate energy by just impact. The key was that this material would not be damaged when the energy was excited.
