Secondary Damage to Aircraft by Ricocheted Small Arms Projectiles and Fragments

Abstract

Under certain conditions of oblique impact against aircraft structures, small arms projectiles (or fragments thereof) ricochet, thereby causing damage to adjoining structures, components, or personnel. This report describes terminal ballistics of caliber .30 AP M2 and 7.62-mm ball M59 projectiles striking 0.375-inch-thick 2024-T351 aluminum and 0.25-inch-thick Ti- 6Al-4V alloy plates over ranges of obliquity and velocity. Effects of these factors upon potential for secondary damage are assessed. Principles for design of aircraft structures to reduce vulnerability to ricochet damage are proposed.
