485 Life and Death Bomb Disposal
After Chen Fei finished speaking, he stretched out his hand in front of Lin Yuan and said, "Give me your binoculars."
Lin Yuan didn't know what he was going to do, so he had to hand over the telescope to him, Chen Fei looked at the cannonball for a while, and asked Lin Yuan: "Isn't this cannonball deliberately launched by the enemy to trap me?" ”
Lin Yuan asked, "What do you mean by that?" ”
Chen Fei said: "There are such weapons on the battlefield, such as the shells deliberately left for the enemy when retreating, these shells have been manipulated, for example: the cartridge is not filled with propellant, but the fuse of the shell, if you use these shells, it will 'boom' and blow your cannon into the sky." ”
Lin Yuan said helplessly: "They don't know that you are coming, how can they deliberately use fake shells to trap you, besides, they wouldn't have thought that we would dismantle the bomb for research, so this shell must be real." ”
Chen Fei nodded and smiled: "That's good, look at this cannonball, its head is stuck in the snow, and the back of the shell is exposed, and there are three protrusions on it, do you know what it does?" ”
Lin Yuan said: "The protrusion at the back is the bullet belt, when the shell moves in the gun chamber, the bullet belt is embedded in the rifling, which is used to guide the shell to rotate in the gun chamber; The first two protrusions are the centering part of the shell, which can be tightly attached to the wall of the bore, and the cannonball will not swing from side to side when it moves in the bore. ”
Chen Fei said: "In other words, these two places will definitely not install fuses?" ”
Lin Yuan said: "That's right, these two places are subjected to a lot of force when they are launched, so it is impossible to install a fuse here. ”
Chen Fei smiled: "That's good, then I'll go dismantle the shell." ”
Lin Yuan grabbed him and said, "You tell me your method first, if it's not reliable, I won't let you go!" ”
Chen Fei said: "If you know the structure of the shell so well, you must know that the inside of the shell is empty, and it needs to be loaded with explosives, and the manufacture of the shell, either casting or forging, must be integrated, and there will be no traces of threaded connection." ”
"And the fuse is installed in the construction of the bomb body, so there will be traces of connection outside, when I go over, first check the tail of the bullet to see if there are traces of connection on it, if not, then the position of the fuse must be in the warhead, I find the connection part of the warhead, and then unscrew the fuse, it's OK."
Lin Yuan said again: "Then what if it's a time fuse?" You go and it explodes! ”
Chen Fei smiled and said, "Don't worry, I have my own way." ”
Chen Fei then called a soldier and said to him, "Go and get me a jug of water and a wrench." ”
Soon the things were delivered, Chen Fei picked them up, carefully walked out of the bunker, slowly approached the shell, and walked to a place about fifteen meters away from the shell. At this time, Lin Yuan saw Chen Fei lying on the ground, and couldn't help but think, "What is he doing?" If he wants to crawl forward, he doesn't have to start at fifteen meters! ”
An even stranger thing happened, I saw Chen Fei lying quietly on the ground, not moving for a long time, Lin Yuan didn't know what he was doing, and when he was wondering, Chen Fei slowly stood up, approached the cannonball, and then approached the snowdrift lightly.
Chen Fei is naturally no stranger to all kinds of shells, he just lay on the ground, in fact, he was determining whether this shell used a time fuse, there is no electronic time fuse in this era, all time fuses are either controlled mechanically, or not controlled by gunpowder column burning, there will be a sound coming out.
This voice is extremely small, it is difficult for ordinary people to detect, but Chen Fei's ear voice is very sensitive, so he can detect it, which can be regarded as his unique skill, but he is not very sure, after all, there are many noises in the surrounding space, so he lay on the ground and listened for a while before he was sure that there was no time for the fuse inside.
Chen Fei then concluded that the fuse inside must be a mechanical trigger fuse, this kind of fuze is very sensitive, and even the rain hits the flying shell, and there is even the possibility of detonating the shell, since it landed and did not explode, on the one hand, because the fuse was not installed accurately enough, and on the other hand, because the snow was relatively soft, so the fuse was not touched.
Chen Feizai carefully observed the position of the cannonball in the snow and found that it was almost lying flat in the snow, which made Chen Fei very excited, so that he had enough space to remove the fuse of the bullet head. Chen Fei looked at the position of the shell and calculated where to pick up the snow so that the warhead of the shell could be exposed.
Chen Fei closed his eyes and calculated without distraction: "If you pick up one-third of the snow in the upper centering part, the body of the projectile will not move, and then move the dug snow to the position behind the warhead, you can pad the shell, and the position of the warhead fuse will be exposed." Chen Fei made up his mind and began to dig up the shells.
Chen Fei took off his gloves and felt a chill in his right hand. He gently picked up the snow on the side of the cannonball, he was also afraid that if he pushed the snow too far, the cannonball would fall directly, and then it would explode, and once such a thing happened, his life would be confessed!
Chen Fei felt that his hands were about to freeze, but he still held back the pain and dug up the snow at the head of the bullet, and the body of the bullet was supported on the snow by the centering part and the bullet belt, but the bullet head was exposed, Chen Fei thought to himself: "It seems that I am not wrong!" It worked! ”
Just when Chen Fei was happy, suddenly, the body of the projectile slid downward, Chen Fei saw it, and his head was blank with fright, in case this shell fell and hit the snow, once it exploded, he would really be finished!
However, the shell slid a few centimeters on the snow, and it was dragged by the snow again, Chen Fei let out a sigh of relief, after such a fright, the hand that was frozen and painful could not feel the pain, Chen Fei took out the kettle from his arms, he did not dare to pour it directly on the snow, afraid that if the water melted the snow, the bullet would move greatly.
So Chen Fei gently poured the water on the bomb body, the water slowly flowed down from the bomb body, piled up between the bullet body and the snow, and slowly froze, Chen Fei saw that the ice layer had accumulated a certain thickness, so he accelerated the speed of pouring water, and soon, the ice froze the bomb body and the snowdrift together.
Chen Fei looked at the thread between the fuse and the missile body, and thought, "As long as the fuse is removed from the missile body, it's done." Chen Fei took out the wrench, gently locked the edge of the fuse, and then slowly strengthened it, the thick ice froze the projectile body, and the fuse began to rotate slowly with the wrench.
This kind of fuze is very safe when the shell is not fired, because there is a set of locking structure inside, which can fix the firing pin in the fuse, so even if the cannonball accidentally falls to the ground, it will not detonate, when the cannonball rotates at high speed in the barrel, the fixing device will disengage the firing pin under the action of centrifugal force, so the fuse can be activated at any time.
Because of this, Chen Fei didn't dare to screw too fast, he was worried that once the force was too strong and the fuse was triggered, the shell would explode, but if he twisted it little by little, it would take a long time, and his hands would be exposed to the air of more than ten degrees below zero, and it was very likely that he would get frostbite!
Chen Fei endured the pain in his hand, twisted the fuse on the cannonball, and just when he thought he was about to lose it, he only felt that his hand was loosened, and the fuse "clicked", fell off the warhead, and fell on the snowdrift.
