阻拦索

着舰钩钩住阻拦索的A-6入侵者式攻击机
未来美国海军将对升级的福特级航空母舰采用先进电磁阻拦索。

阻拦索Arresting gear)是一种安装在航空母舰飞行甲板或其它地面设施上的装置,旨在使固定翼飞机降落时能很快减速,以便在短距离内进入安全的滑行或静止状态。阻拦索一般是由特殊钢材编织制成的绳索,需要具有很高的抗拉强度方能快速吸收高速降落的飞机动能。航母一般在降落跑道的前方装配三至四根阻拦索[1][2]舰载机在航母上降落时,倘若着舰钩无法钩住阻拦索,将造成冲出跑道或无法降落等事故[3]。目前只有英国、美国、俄罗斯、中国拥有此技术。法国航舰使用美制阻拦索,印度航舰使用俄制阻拦索。

拦阻索采用的材料早期为钢缆,目前使用复合材料。其性能的好坏主要是抗疲劳强度这个参数,既拦阻索使用多少次后就必须更换。要尼米兹号航空母舰上,拦阻索使用125次就必须更换。在最新的福特级航母上,使用复合材料的拦阻索可以使用2000次。
