translate by google --------------------------------------------------  这个星期天因为要参与一次电子产品及防弹器材防弹性能测试大比拼，结果不能像往年一样如常地去参观考察性文化节了。 言归正传。这次测试的物品是800M硬盘1个，光驱1个，MP3及充电器1套，80盔1个，护神防弹衣1件。 Because this Sunday to participate in a bullet-proof electronic products and equipment performance testing bulletproof big competition, the results can not be like previous years, as usual to study tour of the cultural festival. Back. The test items is one 800M disk drive, CD driver, MP3 and charger, one Type 80 Helmet, and one bulletproof vest. 出发前拍的测试物图 before the test shoot  测试现场是一个200米靶场，但测试距离被定为100米。测试枪支为81式轻机枪和56式冲锋枪。 This is a 200m range, but the test's distance were identified as 100m. Tests for the T81 light machine gun and T56 assault rifle.  测试物是放在6号靶位的右侧的。在100米只能看到硬盘和光驱的小白点，至于80盔也是一个小绿点。 Tests were placed on the 6th target is to the right of the. In the 100 meters only see the disk drive and CD driver are little white point, the T80 Helmet just a green small point.  测试结果是。80盔轻易爽两面，护神防弹衣被同时贯穿两面。护神的防护能力是5米防54式铅弹，10米防79式铅弹。现在虽然有100米，但却是7.62x39钢芯弹。所以被贯穿前后两面钢板也很正常。 Test results yes.The T80 helmet Breakdown, bullet-proof vests were at the same through. The Guarding God's protective capacity is 5m T54 pistol & lead bullets, 10m T79 submachine gun & lead bullets. Although there are 100 meters, but it is 7.62x39 Steel Core shells. So before and after running through two plate was also normal.  然而，光驱的防弹性能却比预想中好。 However, this CD driver is a good bulletproof performance than expected.  从入口面看，共有三个弹洞从这一面打入光驱，然而在另一侧只有开裂却没有出口，并且在里面倒出两个弹头。可见美军完全可以大量购入废旧光驱代替昂贵的SAPI板。 View from the entrance of a total of three bullet holes from the side into the drive, but the other side is not exports just only cracking, and two bullets inside. This shows that the U.S. army could use the CD driver to replace expensive SAPI armor plate.   然而在另一侧却没有出口，只有严重的拱起变形及一道不足以通过弹头的裂缝。 However, in the only other side with serious deformation and a crack, but not through the bullets.  我们使劲抖了几下，从光驱里倒出了半块破碎的线路板及两枚变形的弹头。 We forced a few buffeting from the CD driver, out a circuit board and two deformation of bullets.  光驱里倒出的弹头，一枚覆铜钢被甲和铅套都严重变形，另一枚铅套已经不知哪里去，而覆铜钢被甲则完全脱出和变形。但两枚的钢芯都基本保持原有形状。 two of Steel Core basic maintain its original shape.  在此，我估计可能是光驱里面的多层结构，产生了类似间隔式复合装甲的效果。当弹头洞穿第一层外壳后就开始偏航和翻滚，结果在击中另一侧的外壳时已经是呈横弹姿态，所以没有集中能量在一点上贯穿另一侧的外壳，而外壳的变形也吸收了大部分的剩余能量。从上图中也可以看出，这个变形的凸形的尺寸也与钢芯尺寸相近。（由于本人水平有限，此分析有谬误之处请不吝赐教。） 补充：光驱没有固定死也可能是原因之一。弹头在碰上第一面时光驱就可能开始翻倒或抖动，吸收了部分能量，而且移动中的光驱也会对弹头偏航产生影响。当然，距离远是另一个原因。PS：下次放到5米试试。 但是，三个进入的弹头却只有一个凸印，那么另外两颗弹头是飞去哪里呢？应该有一枚是飞出，另一枚则可能还没有打到这一面就已经停止。 严正声明：这只是一个单独的个案，由于缺乏大量的试验，不足产生足够的统计数据支持本结论。所以如果有人在防弹衣里塞光驱而被子弹打死，本人概不负责。特此声明！ Here, I guess there might drive the multi-storey structure, which will have a similar interval of the effect of composite armor. When the first shell perforated warheads began after roller yaw and results in the shell hit the other side of the time bomb is a horizontal posture, there is no centralized energy in connection runs through the other side of the shell, the shell deformation has absorbed most of the remaining energy. Also presented above can be seen from this deformation of convex and Steel Core is the size of similar size. (As my limited ability, this analysis is correct fallacy of the requests.) Added: no fixed drive death may also be one of the reasons. Shells hit the first drive on the surface, may begin overturn or jitter, absorbing some energy, the drive and moving Yaw will also have an impact on the warheads. Of course, distance is another reason. PS: The next put five meters try. However, the three entered the warheads but only one凸印, then flew another two warheads is where? There should be one is flying out, the other one could not hit on the side of this has stopped. A solemn statement: This is only a single case, the lack of a large number of tests, a lack of adequate statistical data to support this conclusion. So, if someone drives a bulletproof vest in the Cypriot was shot dead, I will not be responsible for. We hereby declare! 这枚钢芯底部的变形就极有可能是在翻滚过程中磨损其底部而产生的。 At the bottom of the Steel Core deformation is the most likely in the process of wear roller arising from its bottom.  这是光驱被打翻后，子弹从背面打入时造成的入口。 This is the drive was knock over, when bullets enter from the back entrance.  然而从侧面打入的弹头由于没有通过多层板，因此很快就从侧面穿出了。 But from the perspective incoming warheads by the absence of Multilayer, so quickly from the side piercing.  然而我不能够确定这几个洞是不是全是入口。因为上面三个进入的弹头却只倒出两枚，所以应该还有一枚弹头在偏航后从其中一个方向飞出了。 However, I can not identify these holes is not all imported. Because of the above three warheads entered swap out only two, it should have a warhead in yaw after flying from the direction of one of the.  从这里可以看看光驱里面的结构 from here can look at the structure inside  其中应该有弹头从正面穿出，把面板也打得远远的，我没捡回来。尚不清楚这枚飞出的弹头是从哪个方向进入的。 Which should have positive piercing warhead from the panel also played well, I gather not to. This flying is not clear from which direction warheads access.  另外，MP3的充电器也被打爆了，左边的三块是从防弹衣里割下的小钢片，也被轻易穿透。但是，硬盘和MP3始终未被打穿。可见，硬盘的果然是“硬”盘，而MP3没被打穿的例子也表明美军用IPOD挡子弹也应该是真实可行的。 In addition, MP3 charger was uncertain, left three bullet-proof vests, cut off from the small steel, but also easily penetrate. However, hard drives and MP3 has been partially penetrated. Clearly, the hard drive is indeed a "hard" disk, and MP3 Not partially penetrated example also shows that the U.S. army IPOD withstand bullets should also be true feasible.  真正的事实是：硬盘和MP3的防弹原理其实是“避弹”式的，每次子弹都只能打碎它下面的硬土，结果导致硬盘滚到看不见的地方，等我趁中途休息时重新竖起后，还是这样。后来改放到50米，但地势太低不易打中，还是不得不用硬土垫着，结果又是被打碎了硬土，硬盘又滚到看不见的地方了。真是神器啊………… The real fact is: hard drives and MP3 bulletproof principle is actually a "bullet-proof" of each bullet it can only smash the hard soil below, a result drives found its way into invisible places, and so I take advantage midway rest, re-erected, or so. Subsequent to put 50 meters, but not too low-lying hit, or had to use up the hard soil, is the result of the hard soil were broken, the drive also found its way into an invisible place. Really divine utensil ah ... ... 左边的钢心和脱出的包皮是在碎石堆里捡的。而右边的变形弹头和脱出的钢心及包皮是在光驱里倒出来的。 Steel heart and the left side of the foreskin extricate himself from the gravel in the Lancashire seized. Whereas the right warheads and extricate himself from the deformation of steel in the heart and the foreskin is in the inverted drive out.  |
Hahaha, i see now  I spose with all the old hard drives my brother has, i'll be able to make a full armour suit if the SHTF!   ETA I saw a bazillion broken electronics things, and assumed it was just a regular day at the range
