之前跟其他人撕毛子出口弹药问题,

争论印度T90到底有没有能力击穿96/哈利德

所以特意去印度国防部网站搜索了一圈,

发现了一份10年的印度军方为T72和T90寻求弹药收购和技术转让进行国产的招标文件,

综合后面AMK-340A的数据来看,

毛子打靶性能缩水15%还是比较科学的,

因为换算回来480X115%=552

刚好是毛子标称的3BM42M穿深,


这样看来印度不标出AMK-339的穿深数据就很值得玩味了,

因为那东西,也就是3BM42的实际穿深,

极有可能真的只有380,

也就是说,

印度连穿深380的穿甲弹都没法自行设计生产,(2010年)




其实个人找出这个东西来的目的并不是扒印度的底,

而是针对毛子外贸最好的弹药是3BM42没有更好弹药可用这一点,

事实证明,

毛子有卖更好的弹药,


只不过这玩应也不咋地就是了,

不过同时的,

豹2前期型号连3BM42这种380穿的东西都能打穿,

也可以相应看出来西方坦克的防御到底是什么水平,

是不是只有毛子在吹了,




后附PDF文件下载,








数据里面的穿深都是2000M斜靶数据,事实上个人对所谓的什么半无限非常不感冒,

因为设计出来的穿甲弹是不可能针对于无限厚的靶板的,

对于非无限厚,

针对厚度所设计的穿透模型就是最科学有效的,

所谓的半无限,

个人看来单纯就是某些人为了给特定弹种上个DEBUFF拿出来的说辞,

没有任何意义和参考价值


另外一点就是,

对于军迷们嘴巴里非常不屑的400-500穿深的弹药,

貌似满地球也没几家能量产,

对于军迷们嘴巴里非常不屑的400-500穿深的弹药,

说豹2早期防护不行也不必

同期的T64之流防护同样好不到哪去

乌克兰内战一堆被3BM22穿了正脸
说豹2早期防护不行也不必

同期的T64之流防护同样好不到哪去

T64是60年代的设计,防护的重点在提升防破甲弹的能力。复合装甲的填充物是聚酯纤维。T64防穿大致和T72相当,防破比T72要好一个级别。
当豹2堪用的时候,苏联量产T80了吧。不过直到T80U才用上可靠的氧化铝陶瓷装甲。早期的T80A/B防穿靠的是更厚更重的装甲。
这么说来,中国89反坦克炮的120鸡血炮2000米550毫米的穿甲能力在89年也是挺流弊的。

这个嗑药120的出现,应该是TG过高估计了T72防御力的缘故吧?这水平打T80完全够用。

这叫落后应激症, 当年各种打不穿, 后来都怕了, 各种指标都一直加码。
三哥嘛哈哈


没看出是怎么得出结论的,印度寻求两款125弹药的采购生产和技术转让,一款毛子的42,编号AMK339。一款犹太人的3254M,编号340A。

长杆弹穿甲模型是根据外文资料归纳出的,这个模型实际上是国外工程师用缩小的弹和靶子实验的,根据实验值建立坐标图像,然后放大,得出某材料的弹在一定长径比下着速和(穿深/自身穿杆长度)的图像,可不是什么民科方法

噢,这么回事啊。这个归纳中那个贫铀的自锐效应考虑了吗?没看懂计算过程,好像他们只考虑了硬度。
而且好像贴吧里的结论和大神透出的所谓资料并不完全相符,尤其是在豹二的装甲厚度上。可以请教一下您对此的个人观点吗?

这么说来,中国89反坦克炮的120鸡血炮2000米550毫米的穿甲能力在89年也是挺流弊的。
这是一个中国军刊界创造的神话,别当真。

求教:贴吧里量弹芯长、装甲厚度的民科方法估计出来的坦克穿深与防穿准不准?为什么?
因为这些民科连公式都没理解就搬过来瞎算,自然不准。

长杆弹穿甲模型是根据外文资料归纳出的,这个模型实际上是国外工程师用缩小的弹和靶子实验的,根据实验值 ...
国内就没有把那个公式整明白的贴子。

弹芯长不好说,因为穿甲能力还跟着素、材质、结构、重量等等一系列因素相关。反而没有装甲好估测。
对于复合装甲来说,在一定时间内装甲技术相当的情况下,仍然是越厚的装甲防护越高。但换算均质装甲时,一定要乘以0.7-0.8的系数。也就是说99A的一米装甲,防穿大概相当于700-800毫米均质钢装甲。
所有的复合装甲防护系数均小于1,超过1常用的只有合金钢装甲和钛合金。

表都给你归纳了,直接对照表上的穿深曲线看就行了

根据公开文献,陶瓷基复合装甲配置合理的条件下防穿甲弹能力相当于1.2~1.5倍自身厚度的均匀轧制钢装甲。

如果对公示理解都错了,那算出来的表还能看吗?

都说了这个模型实际上是国外工程师用缩小的弹和靶子实验的,根据实验值建立坐标图像的,然后放大,跟公式又有什么关系?现役长杆弹的穿甲是个很复杂的过程,根本没有什么准确的理论公式可以计算

既然是经验公式那就要严格遵循经验产生的条件来使用。所以也就只能适用于均匀轧制半无限钢制靶板。不能随便推而广之的。

贫铀和钨弹在陶瓷复合装甲上也是两条曲线,而且和均匀轧制钢靶板上的情况正好相反。
