摘　　要：战机及其配装的发动机在战场执行任务时,不可避免地会遭遇敌方防空武器的威胁,终端威胁对施加损伤起关键作用。针对发动机(飞机)在战场执行攻击任务时可能遭遇的不同类型威胁,重点对终端威胁作用机理和威胁模式开展分析。从终端威胁产物杀伤机理(威胁机理)出发,描述了穿透物、破片、燃烧物质、爆炸冲击波、高能激光和生化制剂等常见终端威胁产物的输出特性。在此基础上,对航空发动机典型7大部件遭受的威胁模式开展分析,给出了相关威胁模式可能给各大部件带来的损伤模式。上述威胁分析结果可供发动机及部件易损性分析时借鉴,也可供发动机生存力或易损性设计参考。Fighter jets and their equipped engines are inevitably threatened by enemy air defense weapons when performing missions on the battlefield,and terminal threats play a crucial role in causing damage.For different types of threats that engines(aircraft)may encounter during attack missions on the battlefield,analyses were focused on terminal threats'damage mechanisms.Starting from the dam⁃age mechanism of terminal threat output(threat mechanism),the output characteristics of common terminal threat outputs such as penetra⁃tors,fragments,incendiary materials,blast shock waves,high-energy lasers,and biochemical agents are described.On this basis,analyses were conducted on the types of threats faced by seven typical components of aircraft engines,and the potential damage modes that these threats may cause to each component are presented.The above threat analysis results can be used as a reference for engine and component vulnerability analysis,as well as for engine survivability or vulnerability design.
