Two methods of ejection from tactical aircraft are commonly used: jettisoning the canopy prior to seat travel, and ejecting through a closed canopy. This report compares the ejection injury experience of Naval Aviation in each mode during January 1977-August 1990. During that period, 336 through-canopy and 580 canopy-jettison ejections were accomplished. The former group sustained 10.7% fatal injuries, and only 17.0% egressed injury-free. By comparison, the latter cohort incurred only 4.7% fatalities and fully 31.9% egressed without injury. Analysis of patterns of injuries confirms higher G-forces in through-canopy ejections, resulting in not only more injuries, but more severe injuries. In spite of these findings, we discuss the compelling tactical and financial reasons to consider through-canopy systems.
在座椅弹出前抛弃座舱盖，以及通过封闭座舱盖弹射。本报告比较了1977年1月至1990年8月期间海军航空兵在每种模式下的弹射受伤情况。在此期间，完成了336次穿盖弹射和580次抛盖弹射。前一组的致命伤发生率为10.7%，只有17.0%的人弹射后未受伤。相比之下，后一组的死亡率仅为4.7%，有整整31.9%的人弹射后未受伤。对受伤模式的分析证实，穿盖弹射时的重力加速度更高，不仅导致更多受伤，而且伤势更严重。尽管有这些发现，但我们讨论了考虑穿盖系统的令人信服的战术和财务原因。
