Abstract

Solid obstacles close to (but not in) the flight path of supersonic projectiles influence the flow field and thus possibly the projectile trajectory, even if no contact between projectile and obstacle occurs. In order to qualitatively clarify the basic characteristics of such projectile/obstacle interactions, an initial investigation comprised of two different sets of experiments has been conducted: live rounds were fired from a rifle so that they passed over a flat plate at distances between 0.8 and 2.5 projectile diameters in the first set of tests, followed by a second set where a stationary projectile model was placed in a supersonic wind tunnel to replicate the flow fields of the live range experiments. Time-resolved monochrome schlieren visualization was used as the primary diagnostic tool in the first set of experiments, while singleshot color schlieren images were obtained in the wind tunnel tests.
