Abstract:

The object is to investigate the feasibility of using Dowmetal as armor in aircraft. Dowmetal Type FS, while affording resistance to perforation comparable, on a weight-for-weight basis, to that of good quality non-magnetic steel armor, nevertheless exhibits severe tendencies toward spalling which do not justify its use as aircraft armor. The resistance of perforation of Dowmetal Type FS by ca. .30 AP M2, cal. .50 AP M2 or 20 MM, AP M75 projectiles at normal incidence and at obliquities of 60 degrees or less is well represented.
