On Yawing Motion, Velocity Decay, and Path Deflection of Projectiles Penetrating Cavitating Media

Abstract

Simultaneously flashed orthogonal radiographs were measured to obtain the spatial location and angular orientation of a projectile penetrating gelatin and soil. A methodology that pools the measurements from several firings is developed. As a result of this pooling, the continuous nature of the yawing motion, velocity decay and path deflection ca be inferred. Further, the drag, lift and overturning moment can be obtained as functions of instantaneous yaw.
