In　order　to　study　the　penetration　ability　of　long　rod　projectile　into　non-explosive　reactive　armor,　a　numerical　simulation　model　of　long　rod　projectile　penetrating　into　non-explosive　reactive　armor　at　different　target　angles　is　established　by　using　LS-DYNA　software,　and　the　influence　of　different　target　angles　on　the　penetration　process　of　projectile　is　analyzed.　Through　the　analysis　of　simulation　results,　it　is　known　that　when　the　target　angle　reaches　40　°,　the　impact　of　the　target　plate　on　the　projectile　body　is　the　most　serious.　When　the　target　angle　is　between　30　°　and　40　°,　the　damage　degree　of　the　projectile　body　is　much　greater　than　that　below　30　°　with　the　change　of　the　angle.　©　COPYRIGHT　SPIE.
