As part of the Advanced Shield Phenomenology Program, conducted from 1987 to 1989, a study of the effects of oblique impact on hypervelocity shield damage was performed. The specific threat used was an aluminum cylinder with a mass of 1.75 grams and a length to diameter ratio of one. Incidence angles of 30{degree}, 60{degree}, and 90{degree} were studied. The same layered shield assembly was tested at the different incidence angles. Testing was performed at the Arnold Engineering Development Center, Arnold Air Force Base, Tullahoma, Tennessee. Hydrocode analysis of the interaction of the projectile with the front plate was performed for each of the different incidence angles. 10 refs., 23 figs., 3 tabs.
