轧压均质装甲

轧压均质装甲英文:Rolled Homogeneous Armor;德文:gewalzte homogene Panzerung),缩写成“RHA”,又简称为均质装甲是为钢板之理论基础象征,RHA做为一种基数,用于对照军事装甲车之效能。

变革

直至第二次世界大战结束,大部分坦克的装甲形式以及其它装甲车辆均覆盖着钢板。若要增加车辆的防护,即意味着要增加更厚的钢板,而厚重的装甲相对的也减低了其机动性。从那时以来,一些形式的装甲开始发展出混入一些空气、陶瓷或是贫铀(depleted uranium,简称DU)于钢质之中。在现代化武器攻击下,更大的撞击力量与更高的温度切割冲击,传统的轧压均质装甲已不敷使用,遂由更高等级的装甲取代,而测量单位也跟着有所改变。

更新的装甲估量数被称做“等效轧压均质装甲(Rolled Homogeneous Armor equivalency,简称RHAe),其做为一种粗略估计的单位,或是被炮弹穿透的能力,或是其装甲形式的保护能力,这些不一定是使用钢材。但是,因为各装甲间形式、质量金属以及分工组装等不同,RHAe是否能有效的比对不同形式装甲,仍有许多争议性。

规格

当前美国陆军所使用,RHA钢板产品有军用标准MIL-A 12560[1],而最新标准则使用有MIL-A 46100[2][3][4]。这些非常相似,但实际上在美国钢铁协会(AISI)英语American Iron and Steel Institute的钢板等级中,不同于标准高强度钢材合金4340,虽然其械制造与合金非常的相似。[5]
