Research On Damage Effects Of Chemical Submunition Payload By Kinetic Kill Vehicle Impact

Direct hit-to-kill technology relies on the high kinetic to destroy the payloads of theincoming ballistic missile and significantly reduce the risk for the safety of strewn field,providing an efficient solution to intercept and destroy the incoming ballistic missilewarhead especially in the midcourse phase. This dissertation analyze the damage effect ofchemical submunition payload subject to kinetic kill vehicle （KKV） through thecombination of numerical simulation and ground-based experiment, The results can providea useful guide for direct hit-to-kill vehicle configuration design, intercept trajectory arrangeand ballistic missile damage assessment.The equivalent model for the typical ballistic missile warhead carrying chemicalsubmunition payload as well as the typical kinetic kill vehicle are built based on theconfiguration and performance of payload and vehicle. The influence of endgameencounter parameters and dimensions of KKV on damage effect of payload is analyzedthrough AUTODYN-3D code which reveals how mechanical behavior affectedsubmunition damage mechanism. Moreover, with an explosively-formed penetrator whichis a solution to the difficulty in accelerate the projectile in anti-missile damage experiment,the ground-based experiments to investigate the lethality effects of the simulated chemicalsubmunition payloads subjected to the high velocity penetrator impact are performed. Theexperimental data which implicit the relationship between impact position, impact angle,diameter of penetrator-formed device and damage effect of payload is obtained. Theexperiment results verified the reliability of simulation.
