Abstract

To study particulate and precipitation effects on high-speed vehicles, slender projectiles were fabricated from different relevant materials and subjected to ballistic range experiments. The materials were selected for their applicability to future aerospace structures and include 625 Inconel, 2-D carbon-carbon composite, and fully-dense alumina. The ballistic range tests were carried out at Southwest Research Institute’s (SwRI) Light Gas Gun (LGG) facility to determine material suitability for future studies of the interaction of high-speed projectiles with multiphase flow fields, and required subjecting the projectiles to accelerations in excess of 70,000 G. Only the 625 Inconel projectiles survived launch during the experiment. Projectiles fabricated from 2-D carbon-carbon and from alumina shattered during launch. Schlieren, X-ray, and high-speed optical images of each projectile were collected to study the manner of flight and/or breakup of each projectile. In order to avoid failure in the future, the projectiles were totally redesigned into blunt-nosed, full-bore-rider projectiles. The new designs were analyzed using finite element analysis to increase confidence that they will survive launch during a new round of tests.
