摘要
为提高固定翼飞机的战斗生存能力,提出了一种飞机易损性评估的计算机仿真方法。建立了破片式战斗部作用下的飞机易损性评估模型,该模型主要包括飞机目标描述、毁伤场模型分析、弹目交汇分析、飞机关键部件分析、部件毁伤评估、毁伤树模型等内容。该模型具有以下优点:在弹目交汇过程中考虑了战斗部和目标的速度及方位的影响;在关键部件分析中考虑了部件冗余对易损性评估的影响。以上两方面使易损性评估更能反映实际情况。以此模型为基础,运用VC++开发了飞机易损性评估仿真软件(ATVASS)。并以某固定翼飞机目标为例,用ATVASS软件进行了易损性评估,得到了该飞机在破片式战斗部作用下的易损性规律及改进意见,对飞机防护和生存力的设计具有指导意义。
To improve survivability of fixed wing aircrafts, a simulation method is presented about aircraft vulnerability assessment. A vulnerability assessment model of the fragmentation warhead to the aircraft target is established. This model includes the description of aircraft targets, the damage field model of warheads, the meeting analysis model of aircraft and warhead, the analysis of critical components, the damage assessments of components, the damage tree of aircraft targets. The developed model has the following advantages： taking account of the velocity and azimuth in the meeting model of aircraft and warhead ; taking account of the effect of redundant components on the vulnerability assessment. The above advantages make vulnerability assessment more realistic. Based on the above vulnerability assessment model, an aircraft target vulnerability analysis software called ATVASS （aircraft target vulnerability assessment simulation software） is developed by VC ＋＋. Simulation experiments about a fixed wing aircraft vulnerability assessment impacted by a fragmentation warhead are done with ATVASS. Some suggestions are given to optimize the design of aircrafts. ATVASS is helpful to the disign of aircraft survivability and defence.
