Fluid Filled Containments Impact by a High Velocity Bullet
Authors: ,
Abstract: High velocity fragment or bullet interaction with thin walled fluid-filled containment is investigated. Fragment subsonic motion in compressible fluid was studied being the function of the depth of perforation under the water level in case the containment was partially filled with water and partially with gas having a distinct fluid-gas interface. Approximation formulas were developed making it possible to simulate resistance and drag forces being functions of governing parameters. The developed models were validated by comparing theoretical data with results of experiments. The obtained solutions are applicable for developing concepts for effective shield design protecting from high velocity fragments.
