Aircraft Armor. Perforation Resistance Characteristics of Magnesium Alloys Dowmetal (Type FS, J-1)

Abstract

The object of this projects is to investigate the feasibility of using Dowmetal as armor in aircraft. Dowmetal, while affording resistance to perforation by small arms projectiles comparable, on a weight-per-weight basis, to that of good quality non-magnetic steel, nevertheless exhibits severe tendencies toward spalling which militate against its use as armor. The resistance to perforation of Dowmetal by cal. .30 deg M2, cal. .50 AP M2 or 20 MM. AP M75 projectiles at normal incidence and throughout the entire range of obliquities investigated (0 deg to 70) is well represented.
