打到的那个位置入射角大于30度。

| d**e 发帖数: 1124 | 5 OK, 研究了一下wot wiki, 大概搞清楚了,但还有些疑问。分两个部分考虑:
1.穿深
The base stat of your tank's gun and Shell are used as the basis for this
calculation.
距离很重要:At 100m, you will have 100% of your Shell penetration, but this
decreases linearly down to 80% at 500m.
还有随机的因素:Next, the penetration value is modified by Gaussian
distribution with an upper limit of +25% and a lower limit of -25%. In other
words, your Shell may have an actual penetration value of 75% - 125% of the
displayed value (without range figured).
那在50米,267mm的穿深蛋,75%的随机后仍然有200mm的effective penetration.
2. 装甲
120mm的装甲,其实120mm是极值,不是平均值。但是,每个值都没有包括armor slope,
所以,带有slope的armor真实的effective armor会大于120mm. 而且,因为射入的角
度,也会有影响。需要考虑shell normalization.
引自wot wiki:
The "IS" tank, as well as the majority of vehicles, do not have homogeneous
front/side armor. "IS" armor should be understood as "up to 120/90 mm of
armor" respectively.
如果考虑armor slope的话:
T-54s frontal armor (120mm) which sits at a 30 degree slope is effectively
about 1/cos(20 degrees) = 1,064x thicker or 127,7mm effectiveness (remember
that shell normalization reduces slope angle from 30 to 20 degrees). That
armor, however, is also sloped to the side as well, so effective armor can
be as high as 220mm.
这里我没搞明白怎么从120mm到了220mm. 难道说,front + side 装甲叠加,然后再加
slope? T54是120/80/45 front/side/rear. (120+80)x1.064=212mm 仍然没到220mm
,不是特别明白。
最后,我认为比较正确的算法:
1. shell normalization
攻击角度大概30度,normalization 加10度,所以最终是40度
2. effective armor
= 120/cos(20)/cos(50)=198.6mm
第一个cos(20)是armor slope因素
第二个cos(50)是入射角和shell normlization的因素(90-40=50度)
3. effective penetration
因为在100米以内,没有距离的penalty. 加上+-25%的随机因素,effective
penatration的range应该是200mm到333mm之间。
最后结论应该是打穿。
