Impact Fuze Performance in Snow (Initial Evaluation of a New Test Technique),
Abstract
Snow greatly reduces the effectiveness of impact-fuzed projectiles. In order to obtain maximum effectiveness in a winter battlefield environment, design of new fuzes and evaluation of current equipment requires detailed knowledge of the snow penetration event. Fuze performance data under various impact conditions can be obtained by both direct and reverse ballistic test procedures. In the direct test the fuzed projectile is subjected to realistic launch accelerations, but the test presents problem in accurately locating the point of impact and requires telemetry to obtain data from onboard transducers. The reverse ballistic technique, where the target is fired into a stationary projectile, has the advantage of allowing instrumentation in the projectile to be directly wired to recording equipment. However, this technique is difficult to utilize with snow since this material cannot sustain the high acceleration loads involved. (Author)
