Acoustic Directivity Patterns for Army Weapons. Supplement 2

Abstract

Acoustic directivity patterns are given for the Abrams tank (M1-E1) 120-mm main gun. Two types of ammunition were tested: the high-explosive anti- tank training practice round (HEAT-TPT), and (2) the kinetic energy or SABOT round. These data supplement the pattern data presented in CERL Technical Report N-60. They have been included in the weapon directivity load module of BNOISE 3. 2 and made available to users of the Integrated Noise Contour System (INCS). An investigation of the problem posed by sonic boom (ballistic wave) concluded that it should be considered in evaluating the environmental impact of tank ranges for the HEAT-TPT round. If an impact is predicted, measurements specifically designed to study the ballistic wave at long ranges should be performed.
