Determination of Impact Parameters

Abstract

This research program was conducted to establish the deceleration environment experienced in the nose and tail fuze wells of the MK82 for bomb impacts into sand targets. The study was conducted for warhead impact velocities of 600, 900, and 1100 ft/sec and impact angles, from the vertical, from 20 to 70 deg. The contractor's Two-Dimensional Impact and Penetration Computer Program was utilized to establish the time history of the loads applied to the MK82 during the impact and penetration event. This loading environment was then applied to a mathematical structure model of the MK82 to establish the deceleration environments experienced by both fuzes during the penetration event. The results of this analysis indicated that the flexibility characteristics of the warhead have a large influence upon the fuze well deceleration environments and generated deceleration magnification factors as high as 1.8.
